SUMMARY s- 1 INTRODUCTION/BACKGROUND The Carlsbad Municipal Water District (CMWD) and Carlsbad Sewer District (CSD) propose to implement the Water and Sewer Master Plan Updates. This DraFt Program Environmental Impact Report (EIR) addresses the potential environmental consequences of the updated Master Plan projects. The CMWD and CSD are responsible For the respective maintenance, operations, and management OF water distribution and sewer collection systems in the City OF Carlsbad (City). Each District proposes to implement an update to their Master Plan For the provision OF inhastructure services throughout the City. The Water Master Plan and Sewer Master Plan represent comprehensive programs For the phased and orderly development of water and sewer utilities for future needs OF the City. They consist OF individual capital improvement projects to construct new facilities and modifjr or expand existing Facilities that would be needed to implement the Master Plan Updates. The CMWD Board OF Directors is the decision-malung body For the CMWD. The Carlsbad City Council is the decision-making body for the CSD. Together, CMWD and CSD will be Co-Lead Agencies in preparing this Program Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act of 1970 (CEQA) statutes (Cal. Pub. Res. Code, 21000 et seq., as amended) and implementing State CEQA Guidelines (Cal. Code Regs., Title 14, 15000 et seq., 1998). s-2 PURPOSE AND SCOPE OF REPORT The purpose OF this Program EIR is to assess and disclose potential impacts to the physical environment associated with construction and operation OF the proposed updates to the Water and Sewer Master Plans. This document provides program-level, and in some cases project-level, information for consideration by decision-makers and the general public. This Program EIR focuses on the 10 issue areas OF Aesthetics; An Quality; Biological Resources; Cultural Resources; Geology and Soils; Hazards and Hazardous Materials; Hydrology and Water Quality; Land Use and Planning; Noise; and Transportation/Traffic. Other issue areas, including Public Services and Recreation, are not evaluated in detail in Chapter 4.0 OF this Program EIR and are addressed as required by CEQA in Section 6.4 (EFfects Not Found to be Significant). July 2003 31 94-04 s-I Carlsbad Water and Sewer Master Plan Updates - Program EIR Summary Chapter 2.0 describes the project in detail, including the project’s objectives and characteristics. Chapter 3.0 provides the existing environmental setting. The Environmental Analysis section of the Program EIR (Chapter 4.0) addresses each relevant issue in detail by describing existing conditions, discussing potential impacts and their significance, and proposing mitigation measures to avoid or reduce identified significant impacts. The mitigation measures will be incorporated into a Mitigation Monitoring and Reporting Program (MMRP) to be adopted by the Districts as conditions of approval for the project. Cumulative impacts are assessed in Chapter 5.0, and other considerations required by CEQA are discussed in Chapter 6.0. Alternatives to the proposed project are addressed in Chapter 7.0. Chapter 8.0 identifies the list of preparers, and Chapter 9.0 provides the references used in the preparation of this document. s-3 ENVIRONMENTAL PROCEDURES UNDER THE CALIFORNIA ENVIRONMENTAL QUALITY ACT This Program EIR has been prepared by the CMWD and CSD in accordance with the requirements of CEQA and the State CEQA Guidelines, as amended. An EIR is an informational document that is designed to inform decision-makers, other responsible or interested agencies, and the general public of the potential environmental effects of a proposed project; to examine and implement methods of eliminating or reducing any potentially adverse impacts; and to consider alternatives to the project as proposed. While CEQA requires that major consideration be given to avoiding environmental damage, the lead agency(ies) must balance adverse environmental effects against other public objectives, including economic and social goals, in determining whether and in what manner a project should be approved. To identify key issues and concerns relevant to the scope of the Program EIR, the Districts encouraged participation in the environmental review process from public agencies, special interest groups, and the general public. A major component of this process is public scoping. Scoping is a process designed to determine the breadth of issues to be addressed in the Program EIR. The aspects of the public scoping discussed in this section include the Notice of Preparation (NOP) and areas of controversy identified as a result of public scoping. Notice of Preparation The State CEQA Guidelines include requirements for an early and open process to determine the scope of issues that should be addressed prior to implementation of a July 2003 3 1 94-04 [&AASSOCIAl%S,*INC.I Carlsbad Water and Sewer Master Plan Updates Program EIR s-2 c Summary proposed action (State CEQA Guidelines, 15082 and 15083). The Districts initiated the scoping process on April 28, 2003 through issuance of an NOP that included distribution to the State Clearinghouse (SCH) at the California Office of Planning and Research. The SCH monitors compliance of state agencies in providing timely responses and assigned state identification number (SCH #2003051014) to this EIR. The NOP is included in Appendix A. The NOP provided notification to all federal, state, and local agencies involved with funding or approval of the project, and to other interested organizations and members of the public, that an EIR will be prepared for this project. The NOP was intended to encourage interagency communication concerning the proposed action and provide sufficient background information about the proposed action so that agencies, organizations, and individuals could respond with specific comments and questions on the scope and content of the Program EIR. The Districts held a 30-day public review period to solicit comments on the NOP, beginning on April 28 and ending on June 1, 2003. Appendix A contains the eight comment letters received in response to the NOP. Use of the Program EIR A Program EIR will be used to analyze the first-tier effects of the Master Plan Updates. First-tier EIRs typically cover issues in a broad generalized level of analysis. A Program EIR is typically used for an agency program or series of actions that can be characterized as one large project. Typically, such a project involves actions that are closely related geographically (Cal. Code of Regs., Title 14, 15168(a)(l)), for agency programs (§ 15168(a)(3)), or as individual activities carried out under the same authorizing statutory or regulatory authority and having generally similar environmental effects which can be mitigated in similar ways (5 15168(a) (4)). Program EIRs generally analyze broad environmental effects of the program with the acknowledgment that site-specific environmental review may be required for particular aspects of portions of the program when those aspects are proposed for implementation (5 15168(a)). Once the Program EIR is prepared for the Master Plan Updates, subsequent (or second- tier) activities within the program must be evaluated to determine whether an additional CEQA document needs to be prepared. When the subsequent activities involve site- specific operations, the City would use a written checklist to document its determination whether the environmental effects of the operation were covered in the Program EIR. If July 2003 31 94-04 s-3 Carlsbad Water and Sewer Master Plan Updates Program EIR Summaw the Program EIR addresses the program’s effects as specifically and comprehensively as possible, many subsequent activities could be found to be within the Program EIR scope and additional environmental documentation would not be required (s 15168(c)). If a subsequent activity would have effects that are not within the scope of the Program EIR, the City of Carlsbad would need to prepare a new Initial Study leading to either a Negative Declaration, Mitigated Negative Declaration, or an EIR. Subsequent CEaA documents would incorporate by reference the general discussions from this broader Program EIR, primarily concentrating on the issues specific to the action being evaluated. At the time the Initial Study is performed, the appropriate responsible agency or agencies would be identified. Such agencies would be noticed of the City’s intention to implement or approve the project at the time of public noticing of any such intent to approve or implement the project. The Initial Study is prepared to analyze whether the subsequent project may cause any significant effect on the environment that was not examined in the Program EIR and whether the subsequent project was described in the Program EIR as being within the scope of the Program EIR. If the lead agency, based on the Initial Study, determines that a proposed subsequent project would have no additional effect on the environment that was not identified in the Program EIR and that no new or additional mitigation measures or alternatives may be required, the lead agency is to make a written finding based upon the information contained in the Initial Study that the subsequent project is within the scope of the project covered by the Program EIR. Additional procedures for analyzing second-tier projects are described in Section 4.0. s-4 AREAS OF KNOWN CONTROVERSY Commentors on the NOP expressed concerns about potential impacts to energy resources, archaeological resources, impacts to water supply resulting from a proposed seawater desalination project, biological resources including wetlands, sensitive plant and animal species, and impacts to the Agua Hedionda Lagoon. These concerns have been identified as areas of known controversy. July 2003 31 94-04 S-4 Carlsbad Water and Sewer Master Plan Updates Program EIR Profcrrto~I Team 1.7 Compkx Prqrctr Summary s-5 PROJECT OBJECTIVES The CMWD and CSD propose to implement the Master Plan Updates in order to: 0 0 Increase capacity as necessary; 0 0 Reduce maintenance costs. Make facility improvements on aging wastewater infrastructure; Facilitate identified expansion needs; and In addition, in the case of the CSD, a project objective is to reduce the potential for wastewater overflows. S-6 PROJECT LOCATION The project site is located in the northern part of San Diego County within the City of Carlsbad as shown in Figure 2-Y. All project components would be located within the Districts’ boundaries, with two exceptions, as shown in Figure 2-2 (refer to Chapter 2). A proposed water line upsize at the eastern end of Palomar lrport Road (component 26) would be located within the City of San Marcos, and the abandonment of nine water wells is proposed (component 32) near Foussat Road within the City of Oceanside. s-7 PROJECT CHARACTE RlSTl CS The 2003 Master Plan Updates for Water and Sewer were assembled using the following assumptions, data, and methods: Inventorying data of existing facilities; Examining water billing records for existing development; Employing the City’s Growth Management Database for future development projections; Applying unit factors for anticipated demand; Using models for future infrastructure needs and sizing; and c Calculating fees derived based on estimated construction costs July 2003 31 94-04 s-5 - Carlsbad Water and Sewer Master Plan Updates Program EIR Profernowl Teonv for Campla Rqccu Summarv The Master Plan Updates consist of multi-year studies For Facility improvements within the Districts, and identifjr inhastructure needs to accommodate demands From Future development through City buildout. The plans include a review OF existing and projected Flows, capacity analyses, existing conditions assessment, Capital Improvement Program (CIP), and revisions to the sewer and water connection Fee programs. They would establish a connection Fee program to Fund buildout water and sewer infrastructure identiFied as part OF the planning process. Therefore, three actions are included in the overall project: adoption OF the two Master Plan Updates and adoption OF the connection Fee program. The connection fee program would result in economic effects in that it would update the Fee structure used to obtain Funds For capital projects. As such, the connection Fee program is not subject to CEQA and will not be discussed in the EIR. However, CEQA requires that the lead agencies make Findings For certification OF the project, particularly because the project requires an amendment to the City’s Municipal Code. Accordingly, the City would make Findings for the connection Fee program exemption in the Final environmental documentation. S-8 AFFECTED ENVIRONMENT The environmental setting For the proposed Master Plan Updates includes all 84 project sites within the Cities OF Carlsbad, Oceanside, and San Marcos in the northern portion OF San Diego County, California. The environmental setting is described in terms OF its general characteristics in Chapter 3.0. The environmental setting For each issue area is discussed in more detail in Chapter 4.0 OF this document. s-9 ENVIRONMENTAL IMPACTS AND CUMULATIVE IMPACTS The analysis OF each environmental issue area in Chapter 4.0 includes a description of the existing conditions within the project study area; the criteria For determining signiFicance; an evaluation of how the speciFic resources would be affected by implementation OF the proposed project; program-level mitigation measures to reduce significant impacts; and residual impacts after mitigation. The study area lies within the Cities OF Carlsbad, Oceanside, and San Marcos. ReFer to Figure 2-1 for a vicinity map. The evaluation in Chapter 4.0 is organized generally by the category of environmental effect anticipated by a certain project component. July 2003 31 94-04 I 1 “IIx 16. ASSOCIATES, 6C.l Carlsbad Water and Sewer Master Plan Updates Program EIR S-6 Summary Approach to Impact Analysis The Water and Sewer Master Plan Updates include a total of 84 project components. The analysis contained in this Program EIR is considered to be a first-tier level of analysis for the Master Plan Updates. Impacts are summarized in Tables S-1 and S-2. The data in these tables has several uses. Primarily, Tables S-1 and S-2 are used to identi@ those components that would require additional CEQA review, and as described in Section 1.3, additional CEQA review could take the Form of a Negative Declaration, Mrtigated Negative Declaration, or EIR. Accordingly, Tables S-1 and S-2 also identi@ the project components that would not result in environmental eFfects as a result of construction or operation. These project components would not necessitate additional, second-tier (or project-level) environmental review, as their effects have been adequately assessed in this Program EIR. Tables S-1 and S-2 are designed to serve as a guide for the evaluation of each project component as it comes forward for approval or implementation. Tables S-1 and S-2 are based on known conditions and an evaluation of probable future conditions. Since future conditions may change, the First step in environmental review of future projects under this Program EIR should be to ascertain if future conditions are different from present assumptions, and to determine if environmental review has already been accomplished. For example, where pipelines are assumed in this Program EIR to be located in street rights-of-way, this first check should include affirming the assumption. Conditions evaluated at this stage for any change could include sizing, location, site disturbance, or other factors. If conditions are as assumed, City stafF shall use the following procedure to establish mitigation on a project-specific basis For all issues where the potential for mitigation requirements is indicated. 0 Each project shall be reviewed to determine if local environmental review has been carried out by the local land use jurisdiction as part of a project for which the local land use jurisdiction was the lead agency under CEQA. IF local review was carried out under CEQA, the City will determine if that review For each issue was sufficient to meet the City’s requirements. If so, further environmental review by the City shall not be required. If further environmental review by the City is required, the City shall review project plans to determine if there is a potential for the project to have a significant July 2003 31 94-04 s-7 Carlsbad Water and Sewer Master Plan Updates. Program EIR Pmfcrrla~l Teams fm Cmpla Prqrct. - Summary effect on the environment using the Tables S-1 and S-2 as a guide, but with the possibility of changed future conditions in mind. 0 Where indicated, environmental review of subsequent projects with the potential for a significant effect or effects shall include the applicable studies, surveys, coordination, or other procedures specified in Chapter 4 of this Program EIR. Biological or cultural resource surveys or jurisdiction coordination for traffic issues, for instance, may be needed to establish project-specific conditions and mitigation measures. Where project-specific studies or other information indicate that significant effects would result and feasible mitigation be implemented to reduce the effect to a level below significance, a Mitigated Negative Declaration may be prepared for the project under review. If project-specific studies indicate that any significant effect would result that cannot be mitigated to a level below significance, a separate project-specific EIR shall be required to address any potential significant effects. Refer to Section 1.3 for more information on assessing first- and second-tier impacts of future projects. Summary of Impacts and Mitigation Tables S-1 and S-2 present potential environmental impacts, and mitigation as applicable, for all Water Master Plan and Sewer Master Plan components within the scope of this Program EIR. Projects are identified in the first column by their reference number, which corresponds to the EIR text and Figure 2-2. The second column identifies the projects by their name. The remaining columns summarize the anticipated level of environmental effect categorized by CEQA issue area, and describes mitigation if necessary. It is anticipated that each project will be evaluated by City staff when appropriate to begin design, approval, and implementation. The mitigation identified in Tables S-I and S-2 is the process to be followed by City staff in evaluating the project at that time. The tables are intended to guide City staff in subsequent environmental assessment of each project, and an Environmental Initial Study will be performed for each project as it is brought forward for implementation. Many of the projects will be carried out as part of private development (mostly residential) projects for which the City has already July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR s-a ProflrrloMl Team for C0mPlU PI0,lCII Summary conducted, is in the process of conducting, or will conduct in the future, separate environmental review. Additional information on the evaluation process is described in the introduction to Chapter 4.0. Based on the analysis in Chapter 4.0 and Section 6.4, the projects identified in the Master Plan Updates were not found to have potentially significant impacts on Aesthetics; Air Quality; Agricultural Resources; Energy Resources; Land Use and Planning; Population and Housing; Public Services; Recreation; or Utilities and Service Systems. As such, these issue areas are not shown in Tables S-4 and S-2. In addition, some issue areas are not shown in Tables S-4 and S-2 because for that issue area, all project components will require site-specific studies, or the specific project components requiring additional studies cannot be determined at this program level of analysis. For Geology and Soils, all project components will require site-specific geotechnical studies for engineering and design, which would determine the actual level of environmental impact to geology and soils. For impacts to paleontological resources, specific locations of potential impact would be those locations considered to be high- to moderately sensitive in paleontological resources. This specific information would become available at the time of grading. Only those considered to be high- to moderately sensitive in paleontological resources would require additional investigation. For Hazards and Hazardous Materials, additional project-level analysis is required to determine the significance of potential hazard effects for all project components. Since hazardous materials sites are subject to changing conditions; e.g., closure of known sites, discovery of new hazardous materials sites, site leakages, and/or remediation of existing sites, it is not appropriate to make a significance determination at this program level of analysis. Details on the known hazardous materials locations would need to be investigated at the project level of analysis for individual project components to determine the specifics on location, type, and status of hazardous materials sites that may be affected. For environmental issue areas, there would not be environmental im cumulative impa Program EIR.

July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates * Program EIR S-I 8 Pr"fm,O"'71 r<om 10, Contplez pro,<<Cc i i Summary I S-10 OTHER CONSIDERATIONS REQUIRED BY CEQA Significant Environmental Effects Which Cannot be Avoided if the Proposed Project is Implemented The Program EIR evaluated the proposed project with respect to Aesthetics; Air Quality; Biological Resources; Cultural Resources; Geology and Soils; Hazards and Hazardous Materials; Hydrology and Water Quality; Land Use and Planning; Noise; Transportation/ Traffic; and Utilities and Service Systems. As described in Chapter 4.0, potentially significant impacts would occur for the issue areas of Biological Resources; Cultural Resources; Geology and Soils; Hazards and Hazardous Materials; Hydrology and Water Quality; Noise; and Transportation/Traffic. As discussed in Chapter 4.0, mitigation measures would reduce impacts for all of these CEaA issue areas. With mitigation, the residual impact is less than significant for all issue areas. Significant Irreversible Environmental Changes Which Would be Caused by the Proposed Project Should it be Implemented Water and sewer infrastructure components, once constructed, may be considered permanent. Occasionally facilities are abandonedhemoved or upgraded once operation has resulted in the deterioration of their working condition. The systems for which water and sewer facilities are a part are integrally dependent on all their worlung components. Should components become deteriorated, malfunction or obsolete, replacement must occur. Because the implementation of many projects within the Master Plan Updates would be implemented far into the future and because implementation and timing may affect land use decisions, adoption of the Master Plan Updates would leave the commitment of resources open in the future. -. The project components would support existing and planned growth within the City and Districts’ service areas. Where impacts are significant as defined by CEQA and the City, this Program EIR includes a process to identify and mitigate such impacts. Having said this, impacts such as changes in the visual appearance of a setting or hillside due to a pump station installation would be considered an irreversible change. Implementation of pipeline facilities within sensitive biological areas also may result in irreversible change to the hydrologic and biological environments of these sensitive areas. - - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR s-19 Summary Construction of all project components would be carried out according to all applicable engineering standards to reduce, as much as possible, accidents related to offsite runoff during or post-construction. It should be noted that accidents From both human and naturally caused situations can compromise the integrity of best management practice mitigation measures. For example, a severe storm of unprecedented level could impact the area; precautions included in the project to prevent damage from occurring as a result of this type of severe event may be compromised. Depending on the type of disaster and the resources impacted, significant irreversible environmental commitments of resources may occur. However, there will likely be mitigation programs which can partially mitigate for large, unForeseen disasters. Following engineering standards set out in the Master Plan Updates is the best defense against an unforeseen event and thereFore an unforseen commitment of resources. Construction of water and sewer facilities involves the relatively permanent consumption of building materials such as pipeline components, wood for stability structures and energy for digging and earthmoving tasks. These resources, although at some extent in the long-term may be recycled, are considered to be permanently consumed. This type of commitment OF resources is neither unusual nor unexpected given the nature of the Facilities and is generally understood to be the tradeoff for benefits the system provides to the community. Growth Inducing Impact of the Proposed Project Induced growth is that which exceeds the planned growth and results from new developments that would not have taken place in absence of the project. Growth inducement impacts can result in accelerated economic or population growth, or the construction of new housing, that either directly or indirectly resulted from building a project. Section 15126.2(d) OF the CEQA Guidelines requires that EIRs discuss whether a proposed project could: - “...Foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding environment. Included in this are projects which would remove obstacles to population growth (a major expansion of a waste water treatment plant might, for example, allow for more construction in service areas). Increases in the population may tax existing community service facilities, requiring July 2003 31 94-04 [&ASSOCIAT%,-INC.( Carlsbad Water and Sewer Master Plan Updates - Program ElR s-20 Summary construction of new facilities that could cause significant environmental effects. Also (the environmental analysis must) discuss the characteristics of some projects which may encourage and facilitate other activities that could significantly affect the environment, either individually or cumulatively. It must not be assumed that growth in any area is necessarily beneficial, detrimental, or of little significance to the environment.” The proposed project is a multi-year master plan for facility improvements within the CMWD and CSD. The Master Plan Updates include a review of existing and projected flows, design criteria, capacity analyses, existing conditions assessment, and CIP. The improvement projects detailed in the CIP range hom minor projects such as manhole replacements, to major infrastructure improvements such as replacement of a sewer main and installation of a new water reservoir. The CIP includes 84 improvement projects to be built by 2020. Generally, growth-inducing projects possess such characteristics as being located in isolated, undeveloped or underdeveloped areas, necessitating the extension of major infrastructure (e.g., sewer and water facilities, roadways, etc.), or those that could encourage “premature” or unplanned growth (Le., “leap-frog” development). While infrastructure improvements, like those planned in the Water and Sewer Master Plans’ CIPs, raises the issue of growth inducement, the proposed project is not considered to be growth inducing because the proposed project would not provide additional long-term employment opportunities, no residences are planned as part of the proposed project, and no extension of services beyond that currently planned for in respective planning documents (e.g., City of Carlsbad General Plan) is associated with the proposed project. In calculating flow projections for the project, the Master Plan Updates relied on recent regional population projections published by SANDAG. The ultimate wastewater flow projections were based on existing unit flow generation rates which were then applied to SANDAG 2020 population projections. Therefore, the CIP wastewater projects would not generate additional population or cumulatively exceed official regional or local population projections. In addition, because no unplanned growth would be served by the project, the project would not remove an obstacle to growth. The facilities in the proposed Master Plan Updates are community service facilities, serving an urban inhastructure necessary to support economic and population growth. Their size and capacities are predicated on the projected growth that relates to the type of land use and the SANDAG population estimates and projections (SANDAG 2020 July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR s-21 Pmfernonal TIOM fm CmnPlu Proiccu Summaw CitiesKounty Forecast). For that reason, the facilities in the Master Plan Updates do not induce growth guided by the City’s planning documents. Effects Not Found to be Significant The CEQA Guidelines (5 15128) require that the environmental document include a brief discussion of various environmental issues that were determined not to be significant. This Program EIR addressed all probable or foreseeable possible effects of the proposed project. Based on the discussions presented in Chapter 4.0, effects were not found to be significant for the following issue areas: Aesthetics; Ax Quality; and Land Use and Planning. Based on the public scoping process for this project (refer to Section 1.3.1), the following issue areas were not considered to be areas of controversy, and were not addressed in Chapter 4.0 of the EIR. Hence, an evaluation of Agricultural Resources, Energy Resources, Population and Housing, Public Services, Recreation, and Utilities and Service Systems, those issues not addressed in Chapter 4.0, is offered in Section 6.4 of this Program EIR. S-11 ALTERNATIVES Three alternatives to the proposed project are described in Section 7.0 of the Program EIR and summarized below. For the Master Plan Updates that are the subject of this Program EIR, alternative locations are not possible. However, the Master Plan Updates are comprised of individual improvement projects and there are or may be possible variation in the size, phasing, location, and implementation of many of the individual projects, especially in the later phases. For these reasons, no alternative location for the project is considered, but a discussion of the variability of individual project alternatives, in the context of the existing and planned system, is included. No Project Alternative Under the No Project alternative, the proposed Water and Sewer Master Plan Updates would not be adopted by the City of Carlsbad. This does not mean, however, that the facilities in the Master Plan Updates or other facilities based on development and need in the city, would not be constructed. All projects in the Master Plan Updates could be constructed or implemented on an individual project basis whether or not the Master Plan Updates are adopted. Potential environmental impacts identified in this Program EIR would still be likely to occur. This alternative would, however, deprive the City of July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR s-22 Summary Carlsbad of a valuable planning tool, and one that is informative for those interested in the City’s future plans and facilities. Most of the projects in the Master Plan Updates are intended to remedy deficiencies that were identified in the modeling of the City’s water and sewer systems or to correct problems or potential problems in the operation of that system. If the Master Plan Updates were not adopted, the deficiencies and potential problems would remain and would still require remedy through, in most cases, the improvement projects that make up the integrated programs in the Master Plan Updates. Likewise, the new projects in the plans are predicated on the improvements needed to make the system adequate to serve the City’s planned future growth. Under the No Project alternative, the same improvements would likely be brought forward for approval as individual projects, but in piecemeal fashion and not as an integrated program that had been evaluated as a single environmental project. In addition, the No Project alternative would deprive the City of the opportunity to streamline environmental review of future projects through the use of the Program EIR and subsequent updates. For these reasons, the No Project alternative offers no environmental advantages in either procedures, impacts, or public information over the proposed Master Plan Updates. Planning and Land Use Alternatives The Water and Sewer Master Plan Updates were developed using the best available information on population growth; proposed, planned, and forecast growth and development; means of effluent disposal; requirements and recommendations for peak flows, volumes, and facility capacities; and other factors affecting future City water and sewer utilities planning. The planning period for the Master Plan Updates is long-term, extending to 2020, and almost all the factors in such long-range planning are to some degree uncertain. Most land use planning, until projects are implemented as buildout of the City proceeds, is subject to change for a variety of reasons. Thus, the Districts’ staff will continue to monitor factors likely to affect land use in the City and identify changes that could affect the forecasts and assumptions used to develop the improvement programs in the Master Plan Updates. Most of the projects in the Master Plan Updates are upgrading and modification of existing facilities. In such cases, the location of the project is usually fixed. Nonetheless, adjustments are possible because the Master Plan Updates are guiding documents rather than rigid templates. July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR S-23 Summary Flexibility in the implementation of the Master Plan Updates will occur at a specific project implementation level. Partly as a result of the mitigation program in this Program EIR, evaluation of the individual projects in the Master Plan Updates can occur at the stage of project approval or implementation. Given the speculative and to some degree uncertain nature of future conditions, this process is the only practical way to assure that feasible alternatives to each project, if desirable or necessary, are developed. As an example, if development plans approved for a given area change the street pattern in that area, the location of pipelines projected in the Master Plan Updates may change. If density or type of development in a given area changes, the storage capacity needed to serve that area, and thus the size of water reservoirs may change, and the capacity of sewer collection facilities may also change. Individual project review in the planning stage is the only time an informed decision on such matters can occur. Environmentally Superior Alternative As analyzed in Section 7.4, the No Project alternative would not result in reduced environmental effects when compared to the proposed project. The proposed project would result in the same or less impacts when compared to the No Project alternative because of its comprehensive program to identify, avoid, and minimize impacts to environmental resources in the overall study area. As such, the proposed project is considered to be the environmentally superior alternative.

The existing Water Master Plan and Sewer Master Plan were adopted by the City of Carlsbad in 1990 and 1992, respectively. The current project represents an update to both of these planning documents. This Draft Program Environmental Impact Report (EIR) addresses the potential environmental consequences of the updated Master Plan projects. The CMWD and CSD are responsible for the respective maintenance, operations, and management of water distribution and sewer collection systems in the City of Carlsbad (City). Each District proposes to implement an update to their Master Plan for the provision of infrastructure services throughout the City. The Water Master Plan and Sewer Master Plan represent comprehensive programs for the phased and orderly development of water and sewer utilities for future needs of the City. They consist of individual capital improvement projects to construct new facilities and modify or expand existing facilities that would be needed to implement the Master Plans. (Note: Once constructed, the facilities remain as a part of the Master Plan; they do not get removed from the Master Plan once built.) The CMWD Board of Directors is the decision-making body for the CMWD. The Carlsbad City Council is the decision-making body for the CSD. Together, CMWD and CSD will be Co-Lead Agencies in preparing this Program Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act of 1970 (CEQA) statutes (Cal. Pub. Res. Code, $, 21000 et seq., as amended) and implementing State CEQA Guidelines (Cal. Code Regs., Title 14, 5 15000 et seq., 1998). 1.1.1 Carlsbad Municipal Water District The CMWD water service area covers approximately 85 percent of the City and includes an area of approximately 32 square miles. Primary land uses in the service area include industrial, residential, and agricultural uses. All of CMWD’s water is supplied through four San Diego County Water Authority (SDCWA) treated water aqueduct connections. The CMWD is totally dependent on the SDCWA supply for potable water needs. Storage is provided by 11 enclosed reservoirs, one reservoir not in use, and one dam (Maerkle Dam). July 2003 31 94-04 1-1 Carlsbad Water and Sewer Master Plan Updates - Program EIR Profenlad TIOW 10. Complu Proiec~r 1 .o Introduction CMWD’s water distribution system includes over 230 miles of distribution mains 6 inches in diameter and larger. The water mains begin at each of the four SDCWA connections and move westward. In addition, four booster pump stations exist in the CMWD system, although one is inactive. Other components within the CMWD system include pressure reducing stations, a number of water wells, a hydro generation facility at Maerkle Reservoir, and two disinfection facilities. 1.1.2 Carlsbad Sewer District The CSD, previously known as the Carlsbad Sanitary District, provides sewer service to the Carlsbad area. Portions of the City’s existing conveyance system date back as far as 1929. The CSD wastewater service area covers approximately 70 percent of the City limits. Sewer service to the southeast corner of the City is provided by the Leucadia Wastewater District (LWD), and the Vallecitos Water District (WVD) provides service to the Meadowlark area along the eastern City limit. The service area is comprised of five major drainage basins, which extend from approximately the eastern service area boundary, and drain west to the coast and ultimately to the Encina Water Pollution Control Facility (WPCF). These sewage drainage basins are defined by the existing and planned interceptors within the City of Carlsbad. In addition to the gravity interceptors, a number of lift stations are required to convey wastewater flows to the Encina WPCF. 1.2 PURPOSE AND SCOPE OF REPORT The purpose of this Program EIR is to assess and disclose potential impacts to the physical environment associated with construction and operation of the proposed updates to the Water and Sewer Master Plans. This document provides program-level, and in some cases project-level, information for consideration by decision-makers and the general public. This Program EIR focuses on the 10 issue areas of Aesthetics; Air Quality; Biological Resources; Cultural Resources; Geology and Soils; Hazards and Hazardous Materials; Hydrology and Water Quality; Land Use and Planning; Noise; and Transportation/ Traffic. Other issue areas, including Public Services and Recreation, are not evaluated in detail in Chapter 4.0 of this Program EIR and are addressed as required by CEOA in Section 6.4 (Effects Not Found to be Significant). July 2003 31 94-04 1-2 Carlsbad Water and Sewer Master Plan Updates - Program EIR Profmiond Team for ComnpLr Ploreru 1 .o Introduction Chapter 2.0 describes the project in detail, including the project’s objectives and characteristics. Chapter 3.0 provides the existing environmental setting. The Environmental Analysis section of the Program EIR (Chapter 4.0) addresses each relevant issue in detail by describing existing conditions, discussing potential impacts and their significance, and proposing mitigation measures to avoid or reduce identified significant impacts. The mitigation measures will be incorporated into a Mitigation Monitoring and Reporting Program (MMRP) to be adopted by the Districts as conditions of approval for the project. Cumulative impacts are assessed in Chapter 5.0, and other considerations required by CEaA are discussed in Chapter 6.0. Alternatives to the proposed project are addressed in Chapter 7.0. Chupter 8.0 identifies the list of preparers, and Chapter 9.0 provides the references used in the preparation of this document. 1.3 ENVIRONMENTAL PROCEDURES UNDER THE CALIFORNIA ENVIRONMENTAL QUALITY ACT This Program EIR has been prepared by the CMWD and CSD in accordance with the requirements of CEQA and the State CEQA Guidelines, as amended. An EIR is an informational document that is designed to inform decision-makers, other responsible or interested agencies, and the general public of the potential environmectal effects of a proposed project; t,o examine and implement methods of eliminating or reducing any potentially adverse impacts; and to consider alternatives to the project as proposed. While CEaA requires that major consideration be given to avoiding environmental damage, the lead agency(ies) must balance adverse environmental effects against other public objectives, including economic and social goals, in determining whether and in what manner a project should be approved. To identify key issues and concerns relevant to the scope of the Program EIR, the Districts encouraged participation in the environmental review process from public agencies, special interest groups, and the general public. A major component of this process is public scoping. Scoping is a process designed to determine the breadth of issues to be addressed in the Program EIR. The aspects of the public scoping discussed in this section include the Notice of Preparation (NOP) and areas of controversy identified as a result of public scoping. 1.3.1 Notice of Preparation The State CEQA Guidelines include requirements for an early and open process to determine the scope of issues that should be addressed prior to implementation of a July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 1-3 Pro}uwnal Teanu fov Complrr Prqecu 1 .o Introduction proposed action (State CECA Guidelines, 5 15082 and 15083). The Districts initiated the scoping process on April 28, 2003 through issuance of an NOP that included distribution to the State Clearinghouse (SCH) at the California Office of Planning and Research. The SCH monitors compliance of state agencies in providing timely responses and assigned state identification number (SCH #2003051014) to this EIR. The NOP is included in Appendix A. The NOP provided notification to all federal, state, and local agencies involved with funding or approval of the project, and to other interested organizations and members of the public, that an EIR will be prepared for this project. The NOP was intended to encourage interagency communication concerning the proposed action and provide sufficient background information about the proposed action so that agencies, organizations, and individuals could respond with specific comments and questions on the scope and content of the Program EIR. The Districts held a 30-day public review period to solicit comments on the NOP, beginning on April 28 and ending on June 1, 2003. Appendix A contains the eight comment letters received in response to the NOP. 1.3.2 Use of the Program EIR A Program EIR will be used to analyze the first-tier effects of the Master Plan Updates. First-tier EIRs typically cover issues in a broad generalized level of analysis. A Program EIR is typically used for an agency program or series of actions that can be characterized as one large project. Typically, such a project involves actions that are closely related geographically (Cal. Code of Regs., Title 14, 5 15168(a)(l)), for agency programs (5 15168(a)(3)), or as individual activities carried out under the same authorizing statutory or regulatory authority and having generally similar environmental effects which can be mitigated in similar ways (5 15168(a)(4)). Program EIRs generally analyze broad environmental effects of the program with the acknowledgment that site-specific environmental review may be required for particular aspects of portions of the program when those aspects are proposed for implementation (5 15168(a)). Once the Program EIR is prepared for the Master Plan Updates, subsequent (or second- tier) activities within the program must be evaluated to determine whether an additional CEaA document needs to be prepared. When the subsequent activities involve site- specific operations, the City would use a written checklist to document its determination whether the environmental effects of the operation were covered in the Program EIR. If July 2003 31 94-04 1-4 Carlsbad Water and Sewer Master Plan Updates . Program ElR 1 .o Introduction the Program EIR addresses the program’s effects as specifically and comprehensively as possible, many subsequent activities could be found to be within the Program EIR scope and additional environmental documentation would not be required ($ 15168(c)). If a subsequent activity would have effects that are not within the scope of the Program EIR, the City of Carlsbad would need to prepare a new Initial Study leading to either a Negative Declaration, htigated Negative Declaration, or an EIR. Subsequent CEQA documents would incorporate by reference the general discussions from this broader Program EIR, primarily concentrating on the issues specific to the action being evaluated. At the time the Initial Study is performed, the appropriate responsible agency or agencies would be identified. Such agencies would be noticed of the City’s intention to implement or approve the project at the time of public noticing of any such intent to approve or implement the project. The Initial Study is prepared to analyze whether the subsequent project may cause any significant effect on the environment that was not examined in the Program EIR and whether the subsequent project was described in the Program EIR as being within the scope of the Program EIR. If the lead agency, based on the Initial Study, determines that a proposed subsequent project would have no additional effect on the environment that was not identified in the Program EIR and that no new or additional mitigation measures or alternatives may be required, the lead agency is to make a written finding based upon the information contained in the Initial Study that the subsequent project is within the scope of the project covered by the Program EIR. Additional procedures for analyzing second-tier projects are described in Section 4.0. 1.4 AREAS OF KNOWN CONTROVERSY Commentors on the NOP expressed concerns about potential impacts to energy resources, archaeological resources, biological resources including wetlands, sensitive plant and animal species, and impacts to the Agua Hedionda Lagoon. These concerns have been identified as areas of known controversy and are analyzed in Chapter 4.0 (Environmental Analysis). In addition, comments were received expressing the desire for coordination with the San Diego County Water Authority (Authority) and Poseidon Resources, who is proposing a water desalination plant in the City of Carlsbad. Commentors expressed the need to - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates * Program EIR 1-5 - P,ofurtonol Born fm Campla Pm,crrr 1 .o Introduction analyze the potential environmental impacts of the proposed desalination project (including its impacts on water supply). However, it is beyond the scope of this EIR to analyze the potential desalination facility for several reasons. As one of the largest proposed desalination projects on the U.S. West Coast, it is uncertain whether the project would ever be constructed due to its location adjacent to sensitive coastal resources and high cost. The project considers several alternatives for pipelines and pump facilities throughout the City of Carlsbad and in adjacent jurisdictions, although the location and sizing of these facilities has not yet been decided. To determine impacts on water supply, more precise information on the proposed routing and size of these lines would be required. Also, it is unknown at this time whether the proposed desalination project would co-mingle desalinated water with other drinking water in the same pipelines, or whether new and separate pipelines would need to be constructed by the Authority. Further, the proposed desalination facility plans are still subject to change in the near future, making it infeasible €or the Water and Sewer Master Plan Updates EIR analysis to remain current with the desalination facility plans. For these reasons, the project is considered to be highly uncertain, both in its totality and in the specific facilities which would be required (e.g., pipelines, pumps, other associated facilities). Thus, it would be infeasible to adequately analyze the desalination facility in this Master Plan program-level document. The desalination project is currently being analyzed in a separate project EIR being prepared by the Authority. Project-specific information regarding the size, location, and nature of the desalination facility including potential impacts to water supply, and appropriate alternatives will be analyzed in that document. 1.5 CONSULTATION AND COORDINATION The CMWD and CSD are the co-lead agencies for this proposed project and have been coordinating with the following agencies and organization: California Regional Water Quality Control Board (San Diego, Region 9) City of Oceanside City of San Marcos U.S. Fish and Wildlife Service California Department of Fish and Game San Diego Archaeological Society Native American Heritage Commission California Of€ice of Historic Preservation California Department of Transportation, District 11 July 2003 3 1 94-04 1-6 Carlsbad Water and Sewer Master Plan Updates * Program EIR Profcrrlaml Teanu for Coniplu Proleu c 1 .o Introduction - 0 SDG&E 0 Encina Wastewater Authority c 0 San Diego County Water Authority 0 Vallecitos Water District c Agua Hedionda Lagoon Foundation 0 Leucadia Wastewater District July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 1-7 P.of.mo"d Teeom for ComplP Pm,ectA 1 .o Introduction THIS PAGE INTENTIONALLY LEFT BLANK July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 1-8 P,oferrwriol Tram io, Coniplcx Prqrclr CIlAPl€R 2.0 PROJ€CT D€SCRIPTION .- This chapter provides a description of the proposed project, the environmental effects of which are evaluated in Chapter 4.0 of this EIR. The project objectives and project location are described in this chapter, followed by a description of project characteristics and a summary of project approvals that would be required. 2.1 PROJECT OBJECTIVES The CMWD and CSD propose to implement the Master Plans in order to: 0 Make facility improvements on aging infrastructure; 0 Increase capacity as necessary; 0 0 Reduce maintenance costs. Facilitate identified expansion needs; and In addition, in the case of the CSD, a project objective is to reduce the potential for wastewater overflows. 2.2 PROJECT LOCATION The project site is located in the northern part of San Diego County within the City of Carlsbad as shown in Figure 2-1. All project components would be located within the Districts’ boundaries, with two exceptions, as shown in Figure 2-2. A proposed water line upsize at the eastern end of Palomar Airport Road (component 26) would be located within the City of San Marcos, and the abandonment of nine water wells is proposed (component 32) near Foussat Road within the City of Oceanside. 2.3 PREVIOUS MASTER PLANS Master planning for water and sewer infrastructure has been conducted previously in the City. The current plans represent updates to previous master planning documents. Summaries of recent Water and Sewer Master Plans are provided below, followed by a description of the current updates. 2.3.1 Previous Water Master Plans The original Water Master Plan was approved in 1990 and prepared by MacDonald- Stephens Engineers. A subsequent update, prepared in 1997 by ASL Consulting Engineers, revised and updated population projections, City planning criteria, and specific project July 2003 31 94-04 2-1 Carlsbad Water and Sewer Master Plan Updates Program EIR Camp Pendleton -Miles FIGURE City of Carlsbad Water and Sewer Master Plans Vicinity Map 2.0 Project Description development plans. The 1997 Master Plan Update identified the facilities required to serve existing and projected potable water demands within the service area and adjacent areas of influence. The 1997 document was not formally adopted by the City of Carlsbad, and as such, the recommendations made in the 1997 Update have been incorporated into the current 2003 Master Plan Update and are evaluated in this Program EIR. 2.3.2 Previous Sewer Master Plans 1987 Master Plan of Sewerage The 1987 Master Plan of Sewerage was prepared by Wilson Engineering and was the first plan prepared in accordance with City of Carlsbad Growth Management Plan. In 1987, the majority of development in Carlsbad was along the coastal strip and was predominantly residential. The population of the 1987 study area was estimated at 39,000, and the ultimate population was projected to be 95,700. In 1987, the ultimate average flow from the City of Carlsbad was projected to be 13.41 million gallons per day (mgd). 1992 Master Plan of Sewerage The 1992 Master Plan of Sewerage was prepared by Wilson Engineering and was an update of the 1987 Master Plan. By 1992, the population of the study area had increased to 65,000 and the ultimate population projection had increased to 130,000. Development was starting to progress inland and the percentage of commercial/industrial development had increased since the last Master Plan. The projected population growth curve first developed in the 1987 Master Plan was revised to increase more rapidly through the year 2000, and then flatten out to an annual growth rate of approximately 1 percent from the year 2000 to buildout. In 1992, the ultimate average flow projection was increased slightly from the 1987 projection to an estimated flow of 13.84 mgd. A CEaA Negative Declaration was prepared for this document, addressing the environmental effects of the Master Plan of Sewerage. 1997 Sewer Master Plan Update In 1994, the City of Carlsbad adopted a new General Plan. The 1997 Sewer Master Plan Update, prepared by Carollo Engineers, incorporated the revised 1994 land use and population projections from the new General Plan. Because ultimate population projections were reduced only slightly from those used in the previous plan, an updated capacity analysis of sewer interceptors was deemed unnecessary. The 1997 update addressed capacity analyses for various sewer trunk lines and the Encina WPCF. July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 2-5 PP oftss-l Team for Conplu Protects 2.0 Project Description Similar to the 1997 Water Master Plan Update, the 1997 Sewer Master Plan Update was not Formally adopted by the City OF Carlsbad. The recommendations made in the 1997 Master Plan Update have been incorporated into the current 2003 Master Plan Update and are evaluated in this Program EIR. 2.4 PROJECT CHARACTERISTICS The 2003 Master Plan Updates For Water and Sewer were assembled using the Following assumptions, data, and methods: 0 Inventorying data OF existing Facilities; 0 Examining water billing records For existing development; Employing the City's Growth Management Database for future development projections; Applying unit Factors For anticipated demand; Using models For Future inhastructure needs and sizing; and Calculating €ees derived based on estimated construction costs The Master Plan Updates consist of multi-year studies For facility improvements within the Districts, and identiFy inhastructure needs to accommodate demands €rom Future development through City buildout. The plans include a review OF existing and projected Flows, capacity analyses, existing conditions assessment, Capital Improvement Program (CIP), and revisions to the sewer and water connection Fee programs. They would establish a connection Fee program to fund buildout water and sewer inhastructure identified as part of the planning process. ThereFore, three actions are included in the overall project: adoption OF the two Master Plan Updates and adoption OF the connection Fee program. The connection fee program would result in economic effects in that it would update the Fee structure used to obtain Funds For capital projects. As such, the connection Fee program is not subject to CEQA and will not be discussed in the EIR. However, CEQA requires that the lead agencies make findings For certification OF the project, particularly because the project requires an amendment to the City's municipal code. Accordingly, the City would make findings For the connection Fee program exemption in the Final environmental documentation. July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 2-6 - 2 .o Project Description 2.4.1 2003 Water Master Plan Update The 2003 Water Master Plan Update (DUDEK 2003) evaluates the existing CMWD water distribution system and its ability to meet project demands. Since the most recent Master Plan Update in 1997, a substantial number of residential, commercial, and industrial developments have been constructed and future development has been identified in the City’s 2001 Growth Management Database. The 2003 document presents an update of CMWD’s Water Master Plan for the planning period between 2001 and buildout of the District’s service area, which is anticipated to occur by 2020. Based on the condition of many existing facilities, CMWD reviewed all infrastructure within the service area to identify necessary improvements to existing facilities, capacity improvements, and expansion needs. As stated in Section 1.2.1, the CIP developed in the 1997 Update is included in the 2003 Master Plan Update effort. CIP projects (or project components) of the Water Master Plan include: 0 Installation of 20 new water mains; Replacement or improvements to 5 existing water mains; Installation of two new water storage tanks, and improvements to one existing reservoir; Installation of four new pressure reducing stations (PRS), and conducting capacity improvements to one existing PRS; Installation of one new pump station and increasing the capacity of two other existing pump stations; 0 One new intertie upgrade; 0 Abandoning nine water wells; and Fire flow improvements at 14 locations. These components are shown in Figure 2-2 and briefly described below. The project components are detailed in Table 2-1, including their location, description, and project type.

As such, many of the water pipelines and water mains have been previously documented in separate CEQA documents such as EIRs, mtigated Negative Declarations (MNDs), or Negative Declarations (NDs) as part of those development projects (refer to Figure 2-3). A number of mixed use and residential development projects proposed by other parties have included water line upgrades and capacity analyses as part of those projects, in order to analyze whether adequate water supply would be available to their proposed developments. As such, a number of water lines have been discussed and analyzed in separate CEU documents, which are available for review at the City of Carlsbad Planning Department. As indicated on Figure 2-3, the dashed lines indicate water lines that have been previously addressed in a separate CEQA document, or are currently being reviewed in a separate CEQA document. These include facilities that will be provided or have already been installed by private developers as part of various developments. The solid lines indicate pipelines that are proposed as part of the 2003 Master Plan Update. Table 2-2 provides additional detail regarding prior or current environmental review of pipelines shown on the map. Water Storage Two new water storage tanks are proposed to accommodate water supply needs. The First tank, component 27, is proposed at the existing water tank farm along Black Rail Road near its intersection with Poinsettia Lane. This tank would be approximately 175 feet in diameter, 56 feet high, and would be the fourth tank at that facility. The proposed tank would be the same size as the three existing tanks, approximately 8.5 million gallons. The second proposed water tank, component 28, would be a 15-million-gallon facility at Maerkle dam to supplement existing dam storage. It is proposed to be buried and would be approximately 350 feet wide and 110 feet high. 3 July 2003 31 94-04 2-1 2 - Carlsbad Water and Sewer Master Plan Updates Program EIR Profririoml Teanu for Canpl~ Pmptr 1 I 1 1 I 1 1 1 I 1 1 I 1 I I 1 1 1 1 2 .o Project Description TABLE 2-2 RELATED ENVIRONMENTAL DOCUMENTATION FOR WATER LINES INCLUDED IN CMWD'S WATER MASTER PLAN .ime Green Wanilla 'ink Calavera Hills Master Plan EIR 98-02 CT 00-02 Robertson Ranch LFMP Zone 14 CT 02-1 6 MP 02-03 Cantarini-Holly Springs ElRs LFMP Zone 15 CT 00-1 8 CT 00-21 Road; and two detention basins in the Calavera Creek watershed.

However, due to a more immediate need to prevent potential flooding and related issues, the City wanted to avoid delay and is currently preparing a separate EIR for this project. Pressure Reducing Stations A PRS provides a method of serving water between different pressure zones, from a higher pressure zone to a lower. Four new stations are proposed under the 2003 Master Plan Update. The size of the pressure reducing stations has not yet been determined, but each would be approximately 8 by 12 feet and could possibly be located underground. The facilities would include sump pumps and pressure reducing valves. Two of the stations (components 6 and 35) would be located within the Calavera Hills Master Plan area, near future Cannon Road east of El Camino Real. The third PRS (component 21) is planned for the southeast part of the City along El Fuerte Street, and the fourth (component 1) is located near future Marron Road in the northern section of the City. Also, one existing PRS (component 30) is proposed to be upsized with increased capacity to supply new development in the 375 zone. This PRS is located east of El Camino Real just south of the Cantarini-Holly Springs residential development projects. Pump Stations One new pump station (PS) is proposed as component 20. It would be located at the southeast corner of the El Camino Real/Palomar Airport Road intersection. The pump station would include three pumps and would roughly be 15 by 20 feet in size. Two PS projects (components 29 and 37) would involve conducting capacity improvements to existing stations. Component 29 is required for emergency supply from Maerkle Dam, and component 37 would also include installation of an emergency generator and other onsite improvements. 2.4.2 2003 Sewer Master Plan Update The 2003 Sewer Master Plan Update (DUDEK 2003) represents an update of the CSD’s Sewer Master Plan for the planning period between 2001 and buildout of the District’s service area (anticipated by 2020). In summary, the 2003 Update includes tasks to - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 2-1 8 - Pmfesrtml Taw for Cmplu Pmrrrta 2 .o Praiect Description document existing facilities, project ultimate average wastewater flows, estimate existing and ultimate peak flows, and develop a computer model to perform an existing and ultimate system capacity analysis. The outcome of these analyses is a recommended long- term CIP for improvement of existing wastewater collection and treatment facilities. The 2003 Update also recommends a sewer connection fee to finance the recommended facilities. In the 2003 Master Plan Update, ultimate sewer flow projections are based on the City’s recently compiled Growth Management Database, which projects the number of additional single and multi-family units and the number and size of non-residential buildings at buildou t . The 2003 Sewer Master Plan Update is to include capacity improvements to the existing sewer collection system’s wastewater interceptors. The components of the 2003 plan would involve rehabilitation or replacement activities for existing sewer pipelines and forcemains, improvements to existing lift stations, and removing several lift stations. Refer to Figure 2-2 for the location of these proposed facilities. The previously prepared Master Plan (Carollo 1997‘) addressed improvements and capacity analyses of trunk sewers, and capacity summary of the Encina WPCF. No CEaA documentation was prepared for the 1997 report; as such, the Program EIR will address the effects of implementing the projects recommended in the 1997 study, as well as impacts resulting from implementation of the 2003 Master Plan Update. Table 2-3 shows the proposed projects to be implemented as part of the 2003 project. Vista/Carlsbad Interceptor Capacity Improvements As shown in Figure 2-2, projects proposed in the 2003 Sewer Master Plan Update’s recommended improvements include those related to the VistaKarlsbad Interceptor. The 2003 Update recommends replacement of existing interceptor lines with new 42-inch lines and replacing a parallel forcemain. These activities would all be conducted within existing alignments in roadways; no new lines are proposed. The existing Buena Vista Lift Station forcemain (component 30) consists of parallel 24- and 16-inch diameter pipelines for most of its length. It is recommended that a new 24- inch diameter forcemain replace the 16-inch main and parallel the existing 24-inch main for its entire length. In addition to increasing the station capacity, the new parallel forcemain would reduce peak velocities and increase reliability.

At this program level of analysis, it is assumed that several lift stations would be physically removed rather than abandoned. As subsequent project-level plans become more defined, the CSD may determine to abandon some of the lift stations. Removal is generally a more impactive process on the environment than is abandonment, and as such, this Program EIR will analyze the worse-case scenario for purposes of environmental analysis. As part of the removal process, additional sewer lines are necessary to be installed in the immediate area surrounding the Gateshead, Villas, Woodstock, and La Golondrina lift stations to connect the sewer system to residential development projects. Other Lift Station Improvements Identified in the 1997 Master Plan A detailed survey of the sewer lift stations with respect to the condition, code compliance, standby power, and capacity was performed as part of the 1997 report. A summary of the recommended improvements that have not yet been constructed is provided in Table2-3 and shown on the map on Figure 2-2. All of the recommended improvements would be installed within the footprints of the existing lift stations. Encina Water Pollution Control Facility Projects The 2003 Update includes a sewer connection fee update. The connection fee update includes 11 projects that would be implemented separately by the Encina Wastewater Authority (EWA) as lead agency. As one of six EWA member agencies, the City of Carlsbad is responsible to contribute their cost share of the proposed sewer projects, which would be funded through the connection fee program. The EWA projects are provided in this document to disclose the complete project description of the 2003 Update; however, EWA as lead agency is responsible for conducting separate environmental review for these projects.

A phased CIP has been developed to plan for future water and sewer system improvements. In general, construction would proceed in three individual phases, with the final phase being completed in the projected buildout year of 2020. In the first phase, improvements to the existing water and sewer distribution system will be implemented, including water pipeline projects recommended to improve fire flows and meet redundancy criteria and lift station improvements. Replacement of older water mains and additional capacity improvements are also included. The second phase involves emergency water supply projects, and improvements required to supply the entire distribution system from Maerkle Dam. Included is a new pump station to supply the eastern parts of the City and capacity improvements at the existing Maerkle Pump Station. Also included are transmission main improvements that will be installed with the construction of Cannon Road and College Boulevard, and a transmission main (Water Master Plan component 15). Phase I11 would consist of improvements recommended for the final CIP phase including construction of additional water and sewer pipelines, pressure reducing stations, and operational and emergency storage facilities. Capacity improvements are recommended that would be constructed with commercial/industrial development in various areas throughout the City. These three CIP phases should provide the Districts with a long range planning tool to keep up with growth and provide for expansion of the water distribution system in an orderly manner. It is noted that phasing for recommended improvement projects may be accelerated or deferred as required to account for changes in development schedules, availability of land or rights-of-way for construction, funding limitations, and other considerations that cannot be predicted at this time. 2.5 APPROVALS REQUIRED AND INTENDED USES OF THE EIR The decision to implement the Master Plans is within the purview of the City of Carlsbad City Council, which acts as the decision-making body for both lead agencies.

Comnplu Pr0,ectJ p CHAPT€R 3.0 €NVIRONM€NTAL S€lTING The environmental setting for the proposed Water and Sewer Master Plan Update project includes all 84 project sites, predominantly within the City of Carlsbad in the northern portion of San Diego County, California. Two components are located in other neighboring jurisdictions (within the Cities of Oceanside and San Marcos). The environmental setting is described in this chapter in terms of its general characteristics. The environmental setting for each issue area is discussed in more detail in Chapter 4.0 of this document. The City of Carlsbad is a coastal jurisdiction bordered generally on the north by the cities of Oceanside and Vista, on the east by Vista and San Marcos, and on the south by Encinitas. Approximately 68 percent of the City is undeveloped, with the remainder being developed with a variety of land uses. Of the developed areas, 55 percent is residential uses, 17 percent is commercial and/or industrial uses, and another 17 percent is comprised of open space uses. The remaining 10 percent of the developed areas consists of public uses and utility right-of-ways. The majority of existing commercial development within the City is located along El Camino Real, immediately south of Highway 78, and south of Cannon Road along 1-5. In addition, existing commercial uses predominate the City’s downtown along with numerous hotels and service stations along Interstate 5 (1-5). Industrial land uses are primarily concentrated within the City’s centralized industrial corridor which surrounds Palomar Arport and extends in a broad band generally to the eastern and western City limits. Major roadways in the study area include Interstate 5 (1-5) which runs north to south along the coastal corridor, and State Route 78 (SR-78) and Mission Avenue (SR-76), which provide inter-regional access, moving vehicles through or around the study area. The City of Carlsbad’s transportation system is generally meandering, due to the presence of natural topographic constraints (e.g., steep hills, lagoons). Portions of the I- 5 freeway and SR-78 bring regional traffic into and through the City. Several of the City’s existing major arterials also carry through traffic as well as local traffic. The City of Carlsbad contains three primary arterial roadways including El Camino Real which runs north and south through the center of the City, Palomar Airport Road which runs east/west through the center of the City, and Rancho Santa Fe Road which runs along the southern and easterly boundary of the City. The topography of the study area is very diverse, consisting of inland hills as well as coastal bluffs adjacent to the Pacific Ocean, inland terrain of valley, hill, and ridge formations ranging in elevation from sea level to 600 feet above mean sea level. July 2003 31 94-04 3-1 Carlsbad Water and Sewer Master Plan Updates Program EIR 3.0 environmental Setting - Hydrologically, the study area is located within the San Diego Hydrologic Region, which drains west into the Pacific Ocean. The San Diego Hydrologic Region encompasses approximately 3,900 square miles and is further subdivided into 11 major watersheds. The project components occur in the Carlsbad Watershed. The Carlsbad Watershed occupies approximately 210 square miles, extending from Lake Wohlford on the east to the Pacific Ocean on the west and from Vista on the north to Cardiff-by-the-Sea on the south. This watershed includes the cities of Oceanside, Carlsbad, Encinitas, Vista, and Escondido. The watershed is drained by Buena Vista, Agua Hedionda, San Marcos and Escondido creeks and contains four coastal lagoons, including Buena Vista, Agua Hedionda, Batiquitos and San Elijo lagoons. , - The areas of the City nearest the coast are in the California Coastal Zone.

The Draft HMP was approved by the California Coastal Commission in June 2003. With the other participating jurisdictions, Carlsbad will submit its plan to the U.S. Fish and Wildlife Service (USFWS) and California Department of Fish and Game (CDFG) to support applications for permits and authorization to incidentally “take” listed threatened or endangered species or other species of concern. “Take authorizations” issued by the wildlife agencies through the MHCP will allow for otherwise lawful action, such as land and infrastructure development, that may incidentally take or harm individuals of a species or habitat of such species in exchange for conserving the species inside the preserve system.

A brief description OF visual resources is given followed by the visual impact analysis. 4.1.1 Existing Conditions The City of Carlsbad is aesthetically characterized by a mixture of natural and urban landforms. The natural environment is made up of diverse landforms, rock outcrops, plants and animal resources, natural colors and hues and panoramic public views of the horizon, foothills, lagoons, and the Pacific Ocean. The natural scenic landscape includes rugged coastal bluffs, several expansive low lying coastal lagoons, and numerous valleys and small canyons surrounded by rolling foothills. The urban environment includes historic buildings, landscaping, signage/monuments, and works of art. There is no dominant architectural theme throughout the City; however, there is a concentration of older Victorian style structures in the northwestern portion of the City and many Spanish and Western Ranch style buildings in the southeastern portion. The industrial portion of the City is characterized by large industrial parks nestled into the hills with a variety of glass/concrete office, manufacturing, and warehouse buildings. The topography is also diverse. Along the coast, there are low sandy beaches and high coastal bluffs. From the coast to 1-5, the land is relatively level, sloping upward to the east. East of 1-5, the land becomes generally more hilly, with steeper slopes. The broad floodplains of the three lagoons within City boundaries (Buena Vista, Agua Hedionda, and Batiquitos) spread between hills on either side. Throughout the City are water and sewer utilities facilities. Cylindrical steel or concrete water reservoirs are scattered through the City, and in the neighborhoods where they are located, many are familiar parts of the urban scene to residents. The largest aboveground facilities include the Encina WPCF near the coast along 1-5, Maerkle Dam in the eastern portion of the City, and Lake Calavera Reservoir to the northeast. City of Carlsbad Scenic Corridor Guidelines In 1988, the City prepared Scenic Corridor Guidelines to identify roadways and transportation routes within the City to be designated as scenic corridors, and to suggest July 2003 31 94-04 I&ASSOCumS, INC.1 Carlsbad Water and Sewer Master Plan Updates Program EIR Professtonnl Teanu fm Cmplu Prq~rts 4.1-1 4.1 Aesthetics methods to preserve and enhance the character of those corridors (City of Carlsbad 1994). According to the City’s Circulation Element (1994), Carlsbad has adopted four categories of scenic corridors. Transportation routes with potential corridor status are identified below; however, currently, El Camino Real is the only designated roadway within the City for which a set of development standards have been adopted. Community Theme Corridors. These connect Carlsbad with adjacent municipalities and present the City of Carlsbad to persons entering and passing thought the community. Community Theme Corridors include El Camino Real, Carlsbad Boulevard, Palomar Purport Road, La Costa Avenue, and Melrose Drive. Community Scenic Corridors. These roadways interconnect major subareas of the present and planned Carlsbad community. They include College Boulevard, Cannon Road, Carlsbad Village Drive, Faraday Avenue, 1-5, La Costa Avenue, Olivenhain Road/Rancho Santa Fe Road, and Poinsettia Lane/Carrillo Way. Natural Open Space and Recreation Corridors. These offer spectacular views of waterscapes, landforms, wildlife, and the Pacific Ocean, and include Adams Street/Park Drive, Batiquitos Drive, and Jefferson Street (the portion adjacent to the Buena Vista Lagoon). Railroad Corridor. This corridor presents the City to people passing through by rail, on the Atchison, Topeka, & Santa Fe (AT8rSF) Railroad. 4.1.2 Significance Criteria As stated in Section 4.0, the criteria for determining significance are based on Appendix G of the CEQA Guidelines. A significant aesthetic or visual resources impact would occur if the proposed project is determined to: 0 Have a substantial adverse effect on a scenic vista; Substantially damage scenic resources, including, but not limited to trees, rock outcroppings, and historic buildings within a State scenic highway; 0 Substantially degrade the existing visual character or quality of the site and its surroundings; or July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.1-2 4.1 Aesthetics 0 Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. 4.1.3 Impact Analysis Implementation of the majority of water and sewer components would require temporary disturbance of the project sites to access pipelines and components. Most projects are below-ground installations and would have no visual effect when completed in existing road rights-of-way. In addition, most of the project components are maintenance or improvement projects for existing facilities and property. The large majority of projects proposed under the Master Plans would not result in permanent visual effects. Implementation of the project components would predominantly take place in public roadways, where visual disruption is llkely to be noticeable. The potential construction- related visual impacts could result from grading, pavement removal, trenching, stockpiling of excavated soils, construction materialdequipment storage, and backfilling of trenches. Visual disturbance from construction is short term in nature, and the City has included commitments in the project design to restore road surfaces, in both public and private rights-of-way, to their pre-existing visual condition or better (refer to Table 2-5). The water and sewer master plans include components that might be located outside existing road rights-of-way, or in landscaped areas or where there is native vegetation. In these cases, visual effects could be potentially significant unless vegetation that is removed is replaced, or in the case of natural areas, revegetated to blend with adjacent natural areas. The visual character of the project area and its surroundings would not be adversely affected once construction is completed and the disturbed surfaces are restored to pre-existing visual conditions. Also, some facilities will be designed as parts of private development projects in the development plans subject to City review. In those cases, environmental review of the facilities may be conducted as part of the overall CEQA review of project plans by the City. The modifications proposed to various PRS and PS facilities in the Water Master Plan would involve short-term rehabilitation and upgrade activities. Similar to construction activities on the underground pipeline segments, visual impacts would be short-term and would not result in long-term significant effects to visual resources. New PRS facilities are not anticipated to result in significant visual effects, largely due to the small size of these facilities (approximately 10 by 12 feet), and proposed location July 2003 31 94-04 4.1-3 Carlsbad Water and Sewer Master Plan Updates - Program EIR Aesthetics within existing urban environments. In addition, it is possible that these facilities could be placed underground, which would be determined at the project level of review, thereby totally reducing any long-term visual effect. The new 15 million gallon storage tank to be sited adjacent to the existing Maerkle Reservoir (component 28) is proposed to be buried. Adjacent residential areas in the Ocean Hills community within the City of Oceanside and community south of Shadowridge Drive in the City of Vista would be exposed to the visual impacts of construction, but once construction is complete, no long-term visual impact would result since this component would be underground. Also in that area would be component 29, which is the proposed capacity improvements to the existing Maerkle Reservoir PS. Because the PS is existing, the incorporation of additional facilities at that site to implement the capacity increase is not expected to result in a new land use in the area, and would be visually consistent with the utilitarian appearance of the reservoir and PS. Impacts would be less than significant. Similarly, the new PS proposed at the southeast intersection of El Camino Real and Palomar Airport Road (component 20) would not result in significant visual effects. This project would include three pumps and would be roughly 15 by 20 feet in size. Because PS facilities typically resemble ordinary buildings, even very large pump stations, once constructed, usually are unremarkable features in the landscape for most viewers. Along public. roads, many motorists and area residents may pass them several times daily and remain unaware of their presence. Given the lack of adjacent sensitive receptors and suburban nature of this large, busy intersection, it is not anticipated that construction of the PS at this location would result in a significant visual effect. Nonetheless, the PS appearance can be enhanced by exterior treatment and landscaping, as identified as a project design feature in Table 2-5. Component 33 involves improvements to the existing reservoir at Lake Calavera. The project would replace outlet tower valves and piping, and re-grade the bottom of the reservoir. The re-grading of the reservoir bottom would result in short-term visual effects during construction only, and the replacement of existing features is not expected to result in a significant visual effect. Impacts would be less than significant. - - The removal of the 10 lift stations as part of the Sewer Master Plan Update would involve short-term demolition activity, but once complete, the effect of removing these aboveground infrastructure facilities would be a visual benefit. Improvement projects at 8 sewer lift stations would consist of short-term construction activities that, once - July 2003 31 94-04 4 1-4 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.1 Aesthetics complete, would not result in significant visual impacts. Slightly relocating the existing Agua Hedionda Lift Station (component 32) would not result in significant visual impacts since the project would be located within the existing property boundary and would be similar in nature to the existing facility. c There are no State scenic highways in the project study area (Caltrans 2003); therefore, no impacts would occur. Although the City has its own Scenic Corridor Guidelines, it is anticipated that due to the nature of the project, motorists would not be able to view project construction for any substantial length of time. Any project-related lighting would be short-term and would not remain after the construction period. New light sources associated with the project would be regulated by local ordinance and are not expected to result in an intrusion to the surrounding area. Surface coatings and materials applied to all new structures are not anticipated to result in substantial glare impacts. - - c Although some of the aboveground projects would be located near scenic vistas in the City, these facilities would be designed to protect those vistas (as described in Table 24) such as the use of vegetative screens, fencing, and paint. In some locations where sensitive vistas would be affected, the City has taken additional measures in the past to reduce aesthetic effects. These included incorporating additional design considerations and structural improvements, such as designing lift stations to look like a home rather than an industrial facility. The City would continue to investigate alternative visual buffering and design features to reduce significant impacts on a case-by-case basis. Consequently, the large majority of project components would not result in significant long-term visual impacts. c - - One aboveground project, proposed in the Water Master Plan, has the potential to result in a higher level of visual effects. The visual effect of aboveground structures is dependent on the visibility of the project site; the degree of landform alteration required to implement the project; the size, bulk, color, and prominence of the structure; the number and proximity of viewers; and the landscaping, screening, or enclosures used to mask visually undesirable features. Installation of the new water storage tank (component 27) would result in the introduction of a new aboveground feature into the visual landscape. Typically, reservoirs must be of imposing bulk to hold the volume of water required. Reservoirs are most often cylindrical steel structures, and are situated higher in elevation than most of the surrounding landscape and development, which increases their visibility. While reservoirs can be highly visible features, viewer reactions to them are often mixed. Reservoirs are 31 94-04 July 2003 Carlsbad Water and Sewer Master Plan Updates Program EIR 4 1-5 4.1 Aesthetics familiar features of the landscape in almost all urban, suburban, semi-rural, and rural parts OF San Diego County and many residents of Carlsbad are familiar with these structures near their homes. As such, their presence in the landscape is familiar. For some viewers, however, they are perceived as intrusive, utilitarian elements at odds with the rest of the visual landscape. Component 27 would be visible from adjacent sensitive receptors, particularly the residential areas stemming From Corte Orchidia and Black Rail Road (Encantata). This tank would be approximately 175 Feet in diameter, 56 feet high, and would be the Fourth tank at that facility. The proposed tank would be the same size as the three existing tanks, approximately 8.5 million gallons. As such, there would not be a new land use being introduced to the site. Additionally, as is the case with the existing tanks, vegetative screening would be incorporated into the project, as would using fencing or walls, which would help soFten the appearance OF the new facility. Overall, visual impacts resulting From component 27 would be less than significant. 4.1.4 Mitigation Measures No significant aesthetic efFects have been identified; no mitigation measures are necessary. 4.1.5 Residual Impacts After Mitigation There are no residual visual impacts.

Regulatory authority for air quality in San Diego County exists at the federal, state, and local levels and includes the Federal Environmental Protection Agency (EPA); the California Ar Resources Board (ARB); the San Diego Air Pollution Control District (APCD); and the San Diego Association of Governments (SANDAG). SANDAG, comprised of City and County governments, has only advisory authority. However, SANDAG has the primary responsibility to provide long-range, regional growth and transportation planning and to include air quality considerations in its planning efforts. The EPA has overall authority for maintaining and improving the nation’s air quality as mandated by the Federal Clean Ar Act of 1970. Since enactment OF the Act in 1970, a series of federal and state legislation has been enacted to enhance the quality of air. As a result of this legislation, federal and state pollutant concentration standards have been derived. These standards are designed to protect those people most susceptible to respiratory stress (known as sensitive receptors). Also as a result of the legislation, air quality management districts have been established to measure pollutant concentrations in their air basins and monitor their conformance with federal and state standards. If an air basin does not meet the established air quality standards, the responsible air quality district must prepare an air quality plan to show how the standards will be attained. The San Diego Air Basin (SDAB) is classiFied as a “serious” non-attainment area €or both federal and state standards for ozone (smog). The SDAB also exceeds the state standard for airborne particulate matter PM,,. Management of the air quality in the SDAB is under the authority of the APCD. The APCD has prepared a Regional Air Quality Strategy (RAQS) to comply with state and federal legislation and to attempt to address attainment of both state and Federal air quality standards. National Ambient Air Quality Standards (NAAQS) were established in 1971 for six pollution sources. States have the option to add other pollutants, require more stringent compliance or to include difFerent exposure periods. Those standards currently in effect in California are shown in Table 4.2-1.

Sources of Pollution. Nitrogen oxides (NO,) and reactive organic gases (ROG) are the two precursors to photochemical smog formation. In San Diego County, ROG and NO, are largely emitted from mobile (cars, ships, planes, heavy equipment, etc.) sources (San Diego Air Pollution Control District, 1999). Air Quality Management Planning. Due to the existing air quality in San Diego, more specifically the exceedance of baseline pollutant levels, the APCD is required to develop measures for which pollution control will occur. These measures and several other components of the attainment process are contained in the regional air quality management plan developed jointly by the APCD and SANDAG. Several regional air quality plans have been adopted throughout the 1980s and 1990s under the title Regional Air Quality Strategies (RAQS) . Modifications, improvements and updates to earlier RAQS have resulted in the 1998 version of this report. In 1988, the California Legislature enacted the California Clean Air Act (CCAA). The CCAA requires that each air quality region complete a clean air plan to address compliance with state standards as well as their less stringent federal partners. A basin plan was therefore developed and adopted in 1991 that predicted attainment of all national standards by the end of 1997 From pollution sources within the air basin. - 31 94-04 July 2003 Carlsbad Water and Sewer Master Plan Updates Program EIR - 4.2-2 Profcrsiond Team for Cmpb Pm~~tr c c - 4.2 Air Quality A plan to meet the federal standards for ozone was developed in 1994 through an update of the 1991 State Plan. This local plan was combined with those from all other California non-attainment areas with serious (or worse) ozone problems to create the California State Implementation Plan (SIP). The SIP was adopted by the ARB in late 1994 and EPA in mid-1996. In 1999, the SDAB was downgraded from the list of regions suffering from a “severe” ozone problem to a “serious” ozone problem. The proposed project relates to the SIP and/or RAQS through the land use and growth assumptions that are incorporated into the air quality planning document. These growth assumptions are based on each city’s and the County’s general plan. If a proposed project is consistent with its applicable General Plan, then the project presumably has been anticipated with the regional air quality planning process. Such consistency would ensure that the project would not have an adverse regional air quality impact. The proposed Water and Sewer Master Plans relate only minimally to the RAQS. Emissions from the project are almost entirely exclusive to construction. Except for control of construction dust relating to PM,, production, there are no measures in the RAQS that relate directly to the proposed project. The RAQS for SDAB do not specify significance thresholds for air pollutants generated during construction. Therefore, this analysis uses guidelines published in the South Coast Ar Quality Management District (SCAQMD) CEQA Air Quality Handbook. The proposed project would contribute emissions of PM,, from construction-related dust, and emissions of CO and NO, from diesel-powered equipment. 4.2.1 Existing Conditions The study area, encompassing parts of the City of Carlsbad, and minor parts of the Cities of Oceanside, and San Marcos, is located within the SDAB, and enjoys a Mediterranean climate characterized by warm, dry summers, mild winters, and infrequent rainfall. The principal climatic features include the Pacific semi-permanent subtropical ridge with a shallow marine layer and pronounced low-level inversion, along with the cool California current that moderates temperature variations. Air quality within the basin generally rates from fair to poor. Dispersion of air pollutants is relatively limited, owing to low mixing heights, low-level temperature inversions, and light wind speeds. Local air quality within the study area is degraded by subsidence and radiation inversions. Subsidence inversions occur during the summer months as descending air associated with the Pacific High pressure cell contacts cool marine air. The boundary between the two air layers represents a temperature inversion which traps pollutants. The radiation inversion July 2003 3 1 94-04 4.2-3 4.2 Air Quality develops on winter nights when air near the ground cools by heat radiation and air aloft remains warm. The shallow inversion layer between these two air masses can trap vehicular pollutants such as carbon monoxide and oxides of nitrogen. As this air layer moves eastward it becomes progressively more polluted. This situation is further complicated as trapped hydrocarbons (mobile source emissions) and oxides of nitrogen (stationary and mobile source emissions) react in the presence of sunlight to form photo- chemical smog. Local sources of air pollutants are mostly related to transportation, with vehicular emissions being the primary concern. The APCD currently maintains monitoring stations in Oceanside and Escondido. Historical records from these stations show that the level of ozone pollution in the region periodically exceed €ederal standards. As a whole, the SDAB has been designated as a “non-attainment area” for air pollutants such as ozone, suspended particulates, and reactive hydrocarbons. The ambient air quality summary for the period of 1996-2000 is shown in Table 4-22 4.2.2 Significance Criteria Thresholds for determining significance is based upon Appendix G of the CEQA Guidelines. A significant air quality impact would occur if the proposed project is determined to: Conflict with or obstruct implementation of the applicable air quality plan; Violate any air quality standard or contribute substantially to an existing or projected air quality violation; Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors); Expose sensitive receptors to substantial pollutant concentrations; or Create objectionable odors af€ecting a substantial number of people.

Thresholds for Construction Emissions Specific criteria €or determining whether the potential air quality impacts of a project are significant are set forth in the SCAQMD's CEQA Air Quality Handbook. The following CEQA significance thresholds for construction emissions have been established by the SCAQMD: 0 0 0 2.5 tons per quarter or 75 pounds per day of ROC 2.5 tons per quarter or 100 pounds per day of NO, 24.75 tons per quarter or 550 pounds per day of CO July 2003 31 94-04 16rASSoCLATES* INc.1 Carlsbad Water and Sewer Master Plan Updates .

Standards for localized Criteria Pollutants 0 0 California State one hour CO standard of 20.0 ppm California State eight hour CO standard of 9.0 ppm The significance of localized project impacts depends on whether ambient CO levels in the vicinity of the project are above or below state and federal CO standards. If ambient levels are below the standards, a project is considered to have significant impacts if project emissions result in an exceedance of one or more of these standards. If ambient levels already exceed a state or federal standard, then project emissions are considered significant if they increase one hour CO concentrations by 1.0 ppm or more or eight hour CO concentrations by 0.45 pprn or more. 4.2.3 Impact Analysis Consistency with Air Quality Plans Section 15125(B) of the CEQA Guidelines contains specific reference to the need to evaluate any inconsistencies between the proposed project and the applicable air quality July 2003 3 1 94-04 I& ASSOCIATES, mc.1 Carlsbad Water and Sewer Master Plan Updates - Program EIR P~ofrrrionnl Timu for Conylu Projects 4.2-6 4.2 Air Quality management plan. Transportation Control Measures (TCMs) are part of the RAQS. The RAQS and TCM plan set forth the steps needed to accomplish attainment of state and federal ambient air quality standards. The California ARB provides criteria for determining whether a project conforms with the RAQS which include the following: 0 Is a regional air quality plan being implemented in the project areat Is the project consistent with the growth assumptions in the regional air quality plant The project area is located in the San Diego Air Basin, and as such, is located in an area where a RAQS is being implemented. The project is consistent with the growth assumptions of the City’s General Plan and the RAQS. Also, all CMWD and CSD facilities are subject to and designed to conform with APCD Rules and Regulations governing stationary and mobile sources. Because the Master Plans have been formulated on the basis of local land use planning and regional growth and population forecasts, and because all facilities proposed are subject to regional air pollution control measures, the Master Plans are consistent with regional plans to improve and maintain air quality. Therefore, the project is consistent with the regional air quality plan and will in no way conflict or obstruct implementation of the regional plan. Air Quality Standards Ax quality impacts will result primarily from short-term construction activities, emissions from vehicles used by the sanitation districts’ employees, and the operation of other power-consuming city facilities. Standard equipment used for the rehabilitation and replacement of pipelines can include dozers, rollers, dewatering pumps, backhoes, loaders, delivery and haul trucks, and other equipment. The equipment to be found at any one time on a given construction site varies with the type of project. Short-term impacts will also result from dust generated by surface disturbance to construct the project. Such dust potentially will be a soiling nuisance to parked cars, landscaping/ vegetation or other surfaces. Heavy equipment (mainly diesel-powered) will generate exhaust emissions from on-site activity and hauling of excess dirt offsite, pipe and other construction materials. These impacts are generic to pipeline construction and construction of related facilities. A discussion of these impacts is provided below. All other impacts associated with construction, relative to combustion emissions and fugitive dust, would also be applicable to the project. - July 2003 31 94-04 4.2-7 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.2 Air Quality Fugitive Dust The California ARB estimates that each acre under construction disturbance generates about 100 pounds of total suspended particulates (TSP) or dust per day, if no dust control measures are implemented. Dust control measures, such as frequent watering and periodic street washing near construction access, as required by San Diego APCD rules and City of Carlsbad code requirements, can reduce the dust generation rate by approximately 50 percent. The PM,, fraction for TSP is typically less than half. For purposes of this analysis, a one-acre disturbance site was presumed to generate 30 pounds o€ TSP and 25 pounds o€ PM,, when the site is under active disturbance when “standard” dust control measures are utilized. During construction, it was determined that the active disturbance area on any given day would be no more than approximately 200 feet by 30 feet at any given site, or 0.14 acre. Daily regional PM,, emissions would be approximately 3.5 pounds per day for each area of construction. Even if multiple segments were under construction, the PM,, emissions would still be substantially less than the significance threshold of 150 pounds per day. PM,, emissions resulting from project construction would therefore be considered less than signi€icant. However, the PM,, levels in the SDAB are above the state standard; therefore, while PM,, emissions during construction are short-term and less than significant, measures are required to minimize the generation o€ airborne dust to the maximum extent feasible. These measures, including the application of dust control agents and the use of tarps on soil hauling vehicles, have been incorporated into the project by design, as shown in Table 2-5. No further measures would be required. Dust deposited on parked cars, outdoor furniture or other exposed surfaces from construction related activities including the hauling of excavated materials from the site may create a soiling nuisance. EPA studies have shown that the zone of impact for heavy soiling nuisance extends 50 feet or less from the activity (EPA 1995). Where construction occurs within 50 feet of sensitive receptors, soiling nuisance would occur. Project design features included in Table 2-5, such as halting grading operations during periods of high winds, would ensure that effects would be less than significant. No additional measures would be required. .. July 2003 31 94-04 ~~~~~~ ASSOC~~S~ mC.1 Carlsbad Water and Sewer Master Plan Updates Program EIR Profrrrimlrl Temu for Complu Rorrru 4.2-8 Air Quality Combustion Emissions Equipment exhaust emissions are negligible due to the limited equipment necessary to complete the proposed construction. Exhaust from construction activities would not result in substantial concentrations of pollutants, either locally or regionally. Total daily construction activity impacts from equipment exhaust and fugitive dust cannot be specifically calculated at this program-level of analysis; however, given the type of project, it is likely that impacts would not exceed identified significance thresholds, and would be less than significant. However, the 0, and PM,, levels in the SDAB are above national and state AAQS; therefore, while combustion emissions during construction are short-term and less than significant, project design features have been incorporated into the project to reduce effects to the extent feasible (Table 2-5). No additional measures would be necessary. Additional concerns during construction include traffic delays that may occur as a result of construction vehicles interfering with existing traffic flow, and potential truck queuing near sensitive receptors. Detours, delays and congestion from potential lane closures or slow moving vehicles may cause vehicular emissions of CO and ROG to increase. With an effective traffic control plan (as described in Table 2-5 and Sections 2.3 and 4. YO of this EIR) air quality impacts would be maintained at a level below significance (see Section 4.2.4 below). With implementation of the required dust abatement and exhaust pollution minimization measures found in the project design features (see Table 2-5), emissions associated with project implementation will be further reduced to a level below significant. Implementation of these measures will reduce proj ect-related emissions to a level below significant by controlling construction-generated respirable particulate matter (PM,,) through dust abatement procedures and controlling construction-generated 0, and NO, through proper maintenance of construction vehicles and traffic/construction vehicle management. Long-term emissions associated with travel to and from the project will be minimal. Although air pollutant emissions would be associated with the project, they would neither result in the violation of any air quality standard (comprising only an incremental contribution to overall air basin quality readings), nor contribute substantially to an existing or projected air quality violation.

The proposed project would represent a contribution to a cumulatively considerable potential net increase in emissions throughout the air basin. As described above, however, emissions associated with the proposed project would be minimal. As supported by the preceding discussions, given the limited emissions potentially associated with the proposed project, air quality would be essentially the same whether or not the proposed project is implemented. The proposed project’s contribution to the cumulative impact is not meaningful, and impacts would be less than significant. Sensitive Receptors As noted above, the proposed project would not result in substantial pollutant emissions or concentrations. While sensitive receptors (eg, schools or hospitals) exist in the vicinity of most of the project components, project design features to limit emissions and dust would help to maintain impacts at less than significant levels. The construction of the proposed project could generate fumes from the operation of construction equipment, which may be considered objectionable by some people. Such exposure would be short-term or transient. In addition, the number of people exposed to such transient impacts is not considered substantial, and odor impacts during construction of the project components would be less than significant. The proposed underground water and sewer lines and improvements include few above ground structures. Manholes are proposed in several project components. The manholes would be sealed and opened only for maintenance or service to the line; therefore, potential odors would be minimized, and effects would not be significant. Other aboveground structures that can typically result in odor emissions are sewer lift stations, which are vented to the atmosphere. Two existing sewer components, numbers 1 and 12, currently emit odorous levels of hydrogen sulfide gas, resulting in complaints from adjacent sensitive receptors. The proposed projects would include facilities to ameliorate the odor issues by installing an activated carbon adsorption odor control system. Also, odor control measures would be included in all sewer lift station projects. Odor impacts are not expected to be offensive to a substantial number of people, and would be less than significant. - July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.2-10 - c c I 4.2 Air Quality ~~ 4.2.4 Mitigation Measures No signihcant air quality impacts were identified. 4.2.5 Residual Impact After Mitigation Residual impacts to air quality would be less than significant.

The evaluation of potential impacts of implementation of the proposed project components on those biological resources has been made utilizing existing resource databases and knowledge of design requirements and construction methods. The following discussion includes a description of the methodology of analysis, the results, and conclusions in terms of potential impacts, analysis of significance, and proposed mitigation. The description of existing biological resources is largely based on information in the Carlsbad Habitat Management Plan (HMP) (City of Carlsbad 1999). Resources consulted in the analysis of potential biological resource impacts include vegetation community mapping provided by the City of Carlsbad (Carlsbad 1998), sensitive species data occurrence provided by California Department of Fish and Game (CDFG 2002) and San Diego Association of Governments (SANDAG 2002), and reserve planning information provided from the Carlsbad HMP. No field verification was conducted as part of this analysis. 4.3.1 Existing Conditions Carlsbad is situated along the Pacific Coast in northern San Diego County, California. The coastal portions of Carlsbad are largely developed; however, natural vegetation communities remain in and around the three coastal lagoons and on some of the higher, steeper-sloped, inland portions of the City. Vegetation Communities Natural vegetation communities cover approximately 8,758 acres (36% of the City’s total area). The remainder of the City is agricultural lands (approximately 1,812 acres), disturbed lands (approximately 1,251 acres) or developed lands (approximately 12,749 acres). Figure 4.3-1 illustrates the distribution of vegetation types. Natural communities present within the project area include the following general types: grassland, sage scrub, chaparral, woodland, riparian, marsh, and other wetland types. Below is a brief description of each. July 2003 3 1 94-04 ASSOCL4mS, wc-1 CaTsbad Water and Sewer Master Plan Updates Program EIR Profnrimol Tennu /or Cmiplu I’rajecu 4.3-1 4.3 Biological Resources Grassland Both native and non-native grasslands occur within the City, occupying approximately 1,807 acres within Carlsbad. Native grassland is characterized by perennial bunch grasses such as needlegrass (Nassella spp.) and herbaceous annuals and perennials. This habitat type is often associated with clay soils and frequently occurs as open patches within coastal sage scrub. Non-native grassland is characterized by non-native grasses such as wild oats (Avena spp.), bromes (Bromus spp.), and others (e.g., Gastridium ventricosum, Vulpia spp.). Other species present in this habitat type include telegraph weed (Heterotheca grandiflora), fascicled tarweed (Deinandra fasiculata) , doveweed (Eremocarpus setigerus), Russian-thistle (Salsola tragus), black mustard (Brassica nigra), and tocalote (Centaurea melitensis). Non-native grassland is not considered a sensitive habitat; however, in a few locations it may be a significant resource for raptor foraging, may support sensitive plant species, and may serve as a habitat linkage. Sage Scrub Sge scrub types within Carlsbad include maritime succulent scrub, Diegan coastal sage scrub, and coastal sage scrub-chaparral scrub. Approximately 3,315 acres of sage scrub exist within the City. Maritime succulent scrub includes a variety of succulents, such as fish-hook cactus (Adammilaria diuica), coast cholla (Opuntia profifera), shore cactus (Opuntia littoralis), California desert thorn (Lycium californicum), cliff-spurge (Euphorbia misera), bladder-pod (Isomeris arborea), and several species of dudleya (Dudleya spp.), mixed with typical Diegan sage scrub species. Diegan coastal sage scrub is a drought-deciduous community comprised of aromatic shrubs and subshrubs with a diverse understory of annual and perennial herbs, perennial and annual grasses, and grass-like plants. It occurs primarily on dry south-facing slopes and hillsides or on clay-rich soils adjacent to chaparral or upslope from riparian woodlands. Carlsbad, the largest remaining tracts of Diegan coastal sage scrub are found in the vicinity of Lake Calavera, southeast of Agua Hedionda Lagoon, and near Rancho Santa Fe Road. Coastal sage scrub-chaparral scrub is a transitional community between coastal sage scrub and chaparral types. July 2003 31 94-04 Carlsbad Water and Sewer Master Pian Updates - Program EIR 4 3-2 Biological Resources Chaparral Chaparral habitat in the City has been grouped into two categories: undifferentiated (including southern mixed and chamise chaparral) and southern maritime chaparral. There are approximately 989 acres OF undifferentiated chaparral in Carlsbad. Southern mixed chaparral is a fire- and drought-adapted community composed of a variety of woody shrubs, many of which are “stump sproutersl’ that regenerate rapidly from underground undamaged tissues following fires or other ecological perturbation. It is a heterogeneous community type (i.e., the dominant shrubs vary from site to site). Chamise chaparral is a community where chamise is the overwhelming dominant plant. These chaparral types have a patchy distribution throughout the City, occurring on more mesic north- and west-facing slopes, alternating with coastal sage scrub, grasslands, and oak woodlands. Southern maritime chaparral is simiIar to southern mixed chaparral but occurs on sandstone. It is the most limited chaparral type in distribution, particularly in Carlsbad, and is characterized by several endemic shrubs, including Del b.4ar manzanita (Arctostaphylos glandulosa ssp. crassifolia), wart-stemmed ceanothus (Ceanothus verrucosus), coast spice bush (Cneoridium dumosum), and Nuttall’s scrub oak. In Carlsbad, the major stands of southern maritime chaparral are located northeast of the junction of Palomar Airport Road and El Camino Real; east and west of El Camino Real between Palomar Airport Road and Alga Road; slopes above Green Valley; and east and west of El Camino Real between La Costa Avenue and Olivenhain Road. Woodland Two woodIand types occur in the City: oak woodland and eucalyptus woodland. There are approximately 29 acres of oak woodland and 257 acres of eucalyptus woodland in Carlsbad. Oak woodland, as discussed here, is dominated by coast live oak (Quercus agrifolia), with scattered individuals of other tree species. Eucalyptus woodland is a non-native community. It is dominated by various species of planted eucalyptus (Eucalyptus spp.) that survived around old dwellings or in entire groves (e.g., the Hosp Grove). Although this habitat supports no sensitive plant or wildlife species, it is often used for nesting by raptors and other birds or roosting by bats. July 2003 31 94-04 4.3-5 Carlsbad Water and Sewer Master Plan Updates Program EIR Pmfertaonsl Teom fov Compk Rojrcu 4.3 Biological Resources Riparian kparian types within the City include riparian scrub, riparian woodland, and riparian Forest. Riparian habitats are considered sensitive under Federal and state wetlands regulations and policies. There are approximately 572 acres OF riparian habitat in Carlsbad. As used herein, riparian scrub includes several natural and semi-disturbed wetlands communities, including mule Fat scrub, southern willow scrub, and baccharis/tamarisk scrub. These communities occur along river courses and seasonally nioist drainages. Characteristic areas OF riparian scrub occur: along El Camino Real south OF Batiquitos Lagoon; extending east From the mudflats at the eastern end of Agua Hedionda Lagoon (e.g., Macario Canyon); and along the northern portion of the City south OF Highway 78 in Buena Vista Creek. As used herein, riparian woodland includes sycamore-alder riparian woodland and other riparian woodland. Sycamore-alder woodland is an open to moderately closed, winter deciduous, broadleaFed riparian woodland, dominated by well-spaced western sycamore (Plantanus racemosa). Sycamore-alder woodland is uncommon, occurring primarily in the Sunny Creek area and along a narrow drainage south OF Lake Calavera. kparian Forest, as discussed here, includes southern coast live oak riparian Forest. This type is dominated by coast live oak, with scattered individuals OF other tree species, such as western sycamore (Platanus racemosa), willow (Salk spp.), and Mexican elderberry (Sambucus mexicams) . Marsh Marsh and wetland habitats in Carlsbad include southern coastal salt marsh, freshwater marsh, the unvegetated mud flats and open water areas OF estuaries, and several other aquatic habitat types. All marsh habitats are considered sensitive and are regulated under Federal and state regulations and policies. There are approximately 1,466 acres of marsh habitats within the City. Southern coastal salt marsh is a wetland community that develops in low, Flat estuaries at the mouths OF rivers and streams. Tidal inundation or excessive evaporation results in highly saline conditions around the margins OF lagoons, and it is under these conditions that salt marshes develop. Within Carlsbad, salt marsh habitat is present surrounding July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4 3-6 4.3 Biological Resources portions of Batiquitos Lagoon and Agua Hedionda Lagoon. The habitat type also occurs in limited amounts around Buena Vista Lagoon. _- Freshwater marsh occurs in drainages, seepages, and other perennially moist low places. This community is characterized by perennial, emergent monocots 2-3 m (6-10 feet) tall, such as cattails (Typha spp.) Patches of this habitat are present at the upper ends of Buena Vista, Agua Hedionda, and Batiquitos lagoons, where a mixture of plants of salt and freshwater habitats is encountered. Smaller freshwater marshes grow around the perimeter of Lake Calavera and within riparian scrub communities. Other Wetlands Types Other wetland and aquatic types include disturbed wetland, estuaries, freshwatedopen water, vernal pools and cismontane alkali marsh. Disturbed wetland is not a native plant community. It typically occurs where the natural wetland vegetation has been degraded by mechanical activities or invaded by weedy, nonnative species. Estuarine habitat consists of a semi-enclosed body of water that has a free connection with the open ocean and within which seawater is measurably diluted with fresh water derived from land drainage. This aquatic habitat lacks vascular vegetation and includes lakes, ponds, and reservoirs. Excluding the three major coastal lagoons (Batiquitos, Agua Hedionda, and Buena Vista), the largest open water area in the City is Lake Calavera. There also are a number of smaller natural or artificial ponds throughout the City. Vernal pools are a highly restricted, unique wetland habitat type that contains high numbers of endangered, sensitive, and endemic plant and animal species. This type occurs in several scattered locations throughout the City on marine terraces. Areas in Carlsbad classified as cismontane or alkali marsh are typically disturbed riparian Freshwater marsh that have changed in vegetative character due to agriculture or other disturbance. Plant species found in these locations are often those associated with salt marsh, as well as exotic or weedy species. Areas of cismontane alkali marsh along portions of Encinitas Creek and in the vicinity of natural springs and seeps.

Below is a brief Sun Diego Thorn-rninf (Acanfhominfha ilicifolia) San Diego thorn-mint is federally threatened and state endangered and is restricted to distribution to San Diego County and northern Baja California, Mexico (CNPS 2001; USFWS 1995). In San Diego County, the species is known from Carlsbad and San Marcos south to Sweetwater and Otay Mesa, and east to Alpine (Beauchamp 1986; USFWS 1995).This species is an annual plant that may experience dramatic yearly fluctuations in population size and detectability. The species requires a clay soil substrate, and appears to require particularly a micro-habitat within that general category. It is susceptible to local extirpation by catastrophic fire and surface disturbance (City of Carlsbad 1999). Del Mar Manzanita (Arctostaphylos glandulosa ssp. crassifolia) This federally endangered species occurs on sandstone terraces and bluffs and is associated with southern maritime chaparral. This burl-forming, fire-adapted shrub occurs on sandstone terraces and bluffs in southern maritime chaparral. Individuals are typically long-lived. Del Mar manzanita is restricted to San Diego County and northwestern Baja California, Mexico (CNPS 2001; USFWS 2002). Two major populations of this species have been identified in Carlsbad, in the vicinity of Agua Hedionda Lagoon and Green Valley/Olivenhain (City of Carlsbad 1999). I Thread-leaved Brodiaea (Brodiaea filifolia) This federally threatened, state endangered species generally occurs in heavy clay soils in grasslands or vernal pools. Thread-leaved Brodiaea is known from Los Angeles, Orange, hverside, San Bernardino, and San Diego Counties (CNPS 2001). This species generally occurs in heavy clay soils in grasslands or vernal pools. It is an herbaceous perennial from a corm, and often reproduces asexually by producing corm offsets. A total of ten populations are believed to occur in Carlsbad (CNPS 2001). Warf-stemmed Ceanothus (Ceanothus verrucosus) This species is a federal species of concern and is associated with southern maritime chaparral and southern mixed chaparral. It also forms nearly monotypic stands in some I. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.3-a e 4.3 Biological Resources inland locations. Wart-stemmed ceanothus is limited to western San Diego County and Baja California, Mexico (CNPS 2001) .This evergreen shrub is a highly fire-adapted species whose fire response mechanism is seed germination from a persistent seedbank after exposure to intense heat (CNPS 2001). Del Mar Mesa Sand Aster (Corefhrogyne filaginifolia var. linifolia) Del Mar Mesa sand aster is a federal species of concern and San Diego County endemic that occurs along bluffs or brushy slopes near the coast from Carlsbad southward to Point Loma. This perennial sub-shrub occurs on sandstone terraces and bluffs in southern maritime chaparral and coastal sage scrub. Individuals typically are relatively short-lived. The species probably is an obligate seeder rather than a vigorous stump-sprouter, and may invade disturbed soils readily. Sun Diego Goldensfar (Muilla clevelandii) This federal species of concern generally occurs in heavy clay soils in grasslands. San Diego Goldenstar is endemic to San Diego County (CNPS 2001) where it has been reported from Carlsbad, San Diego, Rancho Bernardo, Poway, and Otay. This species generally occurs in heavy clay soils in grasslands (CNPS 2001). Nuttall's Scrub Oak (Quercus dumosa) Nuttall's Scrub Oak is a federal species of concern and has a disjunctive distribution that includes Santa Barbara, Orange, and San Diego Counties (CNPS 2001). This fire-adapted shrub occurs on sandstone terraces and bluffs in southern maritime chaparral, southern mixed chaparral and coastal sage scrub. Individuals are typically long-lived. Sensitive Animal Species Sun Diego Fairy Shrimp (Branchinecfa sundiegoensis) San Diego fairy shrimp are federally endangered and are usually found early in the season after winter and spring rains in vernal pools on mesas, in roadside ditches, and in shallow (< 30 centimeters) tire ruts (Simovich and Fugate 1992). Hatched eggs incubate at temperatures ranging from 10 to 15 "C. This species occurs in vernal pools from coastal Orange County to northern Baja California, Mexico, from near the coast (Orange County, Camp Pendleton) inland to Ramona (Simovich and Fugate 1992; Brown, Wier and Belk 1994; USFWS 1997). July 2003 31 94-04 4.3-9 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.3 Biological Resources Orange-throated Whiptail (Cnemidophorus hyperythrus beldingi) Orange-throated whiptail is a California species of concern. They are most often associated with open sage scrub habitats with a vegetative cover of about 50%, but are also found in ruderal areas, open chaparral, riparian scrub, and oak woodlands. Orange- throated Whiptail is locally common within its range in the extreme southwest corner of California, which includes parts of Orange, Rwerside, and San Diego Counties, and northern Baja California at elevations below 2,800 feet. Belding’s Savannah Sparrow (Passerculus sandwichensis beldingi) Belding’s savannah sparrow is a state endangered species and is restricted to salt marsh, mud flat, and low coastal strand vegetated habitats. This salt marsh sparrow is distributed along the coastline from Santa Barbara County south to northern Baja California. Salt marsh habitats within Agua Hedionda and Batiquitos lagoons contain major populations of this species. California Least Tern (Sterna antillarum browni) The federal and state endangered California least tern requires coastal beaches and salt flats for colonial breeding and intertidal and estuarine waters for foraging. The colonially breeding species is distributed along the coast from San Francisco Bay to Baja California. Estuarine and salt marsh habitats within Buena Vista, Agua Hedionda, and Batiquitos lagoons support major populations for the California Least Tern. Coastal California Gnatcatcher (Polioptila californica californica) This species is closely associated with coastal sage scrub habitat, especially below 950-foot elevation, and on slopes less than 40 percent (ERCE 1990b; Ogden 1992b; 1993b) and is listed as federally threatened. Within Carlsbad, the number of existing coastal California gnatcatcher pairs fluctuates seasonally and from year to year, based on weather, fires and a number of other factors. Based on current information, estimates of the total coastal California gnatcatcher population in Carlsbad range from 100 to 150 pairs. Light-footed Clapper Rail (Rallus longirosfris levipes) This subspecies is restricted to coastal salt marshes of southern California and is listed as federal and state endangered. Salt marsh habitat associated with Buena Vista, Agua I- July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.3-10 - P~ofcnmI Teom for Canpla Prolecu 4.3 Biological Resources Hedionda, and Batiquitos lagoons have been identified as critical locations for the this species . Southern California Rufous-crowned Sparrow (Airnophila ruficeps canescens) The Rufous-crowned sparrow is a state species of concern and occurs primarily in coastal sage scrub and has declined as a result of habitat loss. Rufous-crowned sparrows occur particularly on steep, rocky slopes with sparse brush intermixed with grassland. Due to the overlap of habitat use by the rufous-crowned sparrow and California gnatcatcher, it is assumed that other rufous-crowned sparrows are located within coastal sage scrub habitat. Least Bell’s Vireo(Vireo bellii pusillus) This migratory songbird breeds mostly in willow-mulefat-dominated riparian woodlands. It is restricted to riparian woodlands in southern California, with the majority of breeding pairs in San Diego, Santa Barbara, and kverside Counties, and is listed as federal and state endangered. No major populations or critical locations have been identified for this species in the planning area. However, in 1998 a new population was discovered in the Agua Hedionda Creek west of El Camino Real (Varnus, 1997). Yellow-breasted Chat (Meria virens) This California species of concern occurs in riparian woodlands and is considered an indicator species for potential least Bell’s vireo habitat and is an uncommon summer resident of riparian woodland/scrub of coastal plain and foothills of California. It is known from several locations along major riparian corridors in the City (City of Carlsbad 1999). Regional Resource Planning Context As a participant in the Natural Communities Conservation Program (NCCP), Carlsbad has prepared a Draft HMP which proposes a comprehensive, citywide program to identify how the City, in cooperation with federal and state wildlife agencies, can preserve the diversity of habitat and protect sensitive biological resources within the City while allowing for additional development consistent with the City’s General Plan and its Growth Management Plan. In so doing, the HMP is intended to lead to citywide permits and authorization for the incidental take of sensitive species in conjunction with private development projects, public projects, and other activities which are consistent with the July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.3-1 1 ProfcrrlaMl Tern p Complu Pm,ctJ 4.3 Bioloclical Resources Plan. These permits would be issued under the U.S. Endangered Species Act, the Based on existing distribution of vegetation communities and sensitive species, Focus Planning Areas (FPAs) were identified in the HMP. The FPAs were further broken down into HMP cores and linkages. Eight core FPAs that are connected to one another and to habitat areas outside the City by a variety of linkages and wildlife movement corridors have been identified. These areas served as a basis for biological planning for the establishment of the proposed preserve system. Certain naturally vegetated areas in the City are too small, edge-effected, or isolated to be considered biological core or linkage areas, but are nonetheless important to preserve design or the conservation of particular species. These areas are designated as Special Resource Areas (SRAs). Conservation of land within the City is implemented as either a 1) existing hardline, 2) proposed hardline, or 3) standards area. The existing hardline preserve areas include both publicly owned land and privately owned land that has been committed to habitat conservation as a result of existing open space regulations, past development approvals or other actions. The proposed hardline represents a number of proposed public and private projects which have submitted proposed hardline conservation design for inclusion in the HMP and the preserve system. Upon approval of the HMP, these proposals will obtain the same conservation status as the existing hardline areas. Take of habitat will be authorized for the remaining portions of the projects. For some key properties within the City which have not submitted proposed hardline designs for inclusion in the preserve system at this time, the HMP includes conservation goals and standards which will apply to future development proposals in these areas (i.e., standards areas). The goals and standards have been arranged according to the Local Facilities Management Zones (LFMZs) to which they apply. 4.3.2 Significance Criteria For purposes of this evaluation, a project component may have a significant effect on the environment if: July 2003 31 94-04 ____~ ~~AssocIATEs~ INc.I Carlsbad Water and Sewer Master Plan Updates - Program EIR Pmf..rionol Teanu fo.

In general, project components were found to either: Have been previously analyzed and evaluated under CEQA by a separate development project (e.g., Kelly Ranch, Calavera Hills); c Have no potential for impacts to biological resources due to a location completely July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR - 4 3-13 PrafzrmMi Tcomr fm Complu Pioiicts 4.3 Biological Resources within a currently urbanized area; Have limited potential for impacts to biological resources mainly due to the existence of known habitats or species adjacent to the proposed project component location; or Have potential for impacts to biological resources due to the existence of known habitats or species within and around the proposed project component location. The potential €or a project component to result in impacts to biological resources was evaluated based on both existing mapped resources and the potential €or resources to develop. Thus, project components which were found to not have a potential to impact biological resources were only determined as such because o€ their location within extensively developed areas. Project components identified as having a potential €or impacts to biological resources are required to have a biological survey report prepared pursuant to CEQA. The discussion of each of these project components below will also provide recommendations €or €ocused surveys. The recommendations €or focused surveys are based on existing mapped resources in the vicinity of the project site. The need €or these surveys should be re-evaluated as updated and more detailed in€ormation is collected from processing o€ the individual project components or from other adjacent development projects. Fi€ty-eight of the project components would not result in significant biological resource impacts based on this program level of analysis. The majority o€ these €acilities are located in existing disturbed areas including road rights-o€-way. The €allowing is a description of the 26 project components that would result in potentially signi€icant impacts to biological resources. These determinations are also summarized in Tables S-I and S-2. Each of these components occurs within or adjacent to known sensitive habitat or species localities and most are within designated standards or hardline conservation areas. As such, implementation of each component identified below has the potential to directly or indirectly affect a sensitive resource and/or a€€ect the establishment of an e€€ective regional preserve system. Wafer Masfer Plan Components Component I - Watermain & PRS Marron Road to Tamarack This proposed watermain (6,600 €eet long) lies within areas mapped as coastal sage scrub and riparian scrub.

Recommended focused surveys include project-level vegetation mapping, wetlands delineation, California gnatcatcher, and spring rare plant surveys. Component 7 7 - Watermain from Terminus of Component 70 to Maerkle Reservoir This watermain, totaling 4,100 feet, would be located in areas of fragmented coastal sage scrub within existing agricultural operations and more consolidated coastal sage scrub south of the reservoir. The project would transverse proposed standards and existing hardline conservation areas. Recommended focused surveys include project-level vegetation mapping, California gnatcatcher and spring rare plant surveys. Component 7 7 - Watermain, Poinseftia Lane from Skimmer Court to Blackrail Road Water component 17 includes installation of a 4,500-foot watermain in the future extension of Poinsettia Lane. The alignment transverses maritime succulent scrub, coastal sage scrub, and oak woodland habitats. Sensitive species known to occur in this area include the federally-listed endangered Del Mar manzanita, California gnatcatcher, Del Mar Mesa sand aster, and Nuttall’s scrub oak. This area is also a proposed standards area under the Draft Carlsbad HMP. Recommended focused surveys include project-level vegetation mapping, California gnatcatcher, wetlands delineation, and spring rare plant surveys. Component 7 9 - Watermain, Aviara Parkway from Plum Tree to Sapphire Drive This proposed watermain would be approximately 3,100 feet long and would cross some fragemented habitat in the eastern portion of the alignment. This habitat is mapped as coastal sage scrub supporting numerous sensitive species including the federally-listed endangered San Diego thorn-mint, California gnatcatcher, and southern California rufous- crowned sparrow. The habitat in this area contains designations for standards and existing hardline conservation areas. As such, recommended focused surveys include project-level vegetation mapping, California gnatcatcher and spring rare plant surveys. Component 20 - Pump Station at El Camino Real and Palomar Airport Road Although this project component is located at a major road intersection, there would be potential impacts to biological resources if the project is sited adjacent to or within extant habitat near the intersection. Habitats existing in this location include coastal sage scrub, southern maritime chaparral, and southern mixed chaparral. No other resources or HMP designations are recorded for this area. However, given the mapped vegetation July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.3-15 Proftuwd TIOW lor Coniplu Proiccu Biological Resources communities, recommended focused surveys include project-level vegetation mapping, California gnatcatcher and spring rare plant surveys. Component 22 - Watermain, Along Carlsbad Boulevard From Avenidu Encinas South This project, although situated entirely within the right-of-way of Carlsbad Boulevard, is sited adjacent to the nesting locations for the Cali€ornia least tern and western snowy plover. Indirect construction noise impacts could occur to nesting species as a result. The future biological analysis would need to include a noise assessment and appropriate mitigation, such as seasonal restrictions on construction, adequate buffer areas, or project design features. Component 28 - Water Reservoir adjacent to Maerkle Reservoir This water reservoir project is located in an area known to support coastal sage scrub and annual non-native grasslands. California gnatcatchers are also known from this area. There are no HMP conservation designations likely to af€ect this project component. Recommended €ocused surveys include project-level vegetation mapping, California gnatcatcher and spring rare plant surveys. Component 29 - Pump Station Improvements at Maerkle Pump Station - - Although this project component includes improvements to an existing PS facility, the PS is located within an annual non-native grassland but adjacent to coastal sage scrub. AS California gnatcatchers are also known from this area. No HMP conservation designations have been proposed for this area. Recommended focused surveys include project-level vegetation mapping, California gnatcatcher and spring rare plant surveys. such, expansion of the facility may affect existing biological resources. - - Component 30 - Gross Pressure Reducing Station Improvements - This facility is located within agricultural and disturbed habitat areas with no known occurrence of sensitive species. However, the area is a proposed standards area under the Draft Carlsbad HMP. Therefore it is recommended that focused surveys include project- - level vegetation mapping and potential sensitive species assessment. - Component 32 - Foussat Road Well Abandonments July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.3-16 Prohrnmd Born fm Compla Rorirtr 4.3 Biological Resources This well abandonment project is located in the City of Oceanside within areas mapped as annual non-native grassland. Occurrences of sensitive species are limited to the adjacent San Luis Rey kver and include riparian species such as the federally-listed endangered least Bell’s vireo, and yellow-breasted chat. Furthermore, the project is located within Offsite Mitigation Zone I under the Draft Oceanside Subarea Plan of the MHCP. This zone allows for development but does have specific mitigation requirements for permanent impacts to habitats including annual non-native grassland. As such, the project should be evaluated to determine appropriate methods of reducing potential adverse indirect impacts on adjacent sensitive riparian habitats. Recommended focused surveys include project-level vegetation mapping and potential sensitive species assessment. The project is currently being investigated by the City in a Mitigated Negative Declaration. Component 33 - Calavera Reservoir Improvements The Lake Calavera Reservoir supports numerous sensitive biological resources including coastal sage scrub, southern mixed chaparral, oak woodland, open water, and riparian scrub habitats. Sensitive species recorded for this area includes the California gnatcatcher. Much of the habitat associated with the reservoir is within an existing hardline conservation area and is a designated mitigation bank. As such, proposed improvements would need to be evaluated with focused surveys to include project-level vegetation mapping, vernal pool assessment, least Bell’s vireo, California gnatcatcher, and spring rare plant surveys. Component 34 - Oceanside Interfie Upgrade This proposed upgrade is within an area mapped as annual non-native grassland. The area does not have any documented sensitive species occurrences or HMP conservation designations. However, the project should be evaluated within project-level vegetation mapping and potential sensitive species assessment. Sewer Master Plan Components Component 2 - North Agua Hedionda Interceptor Rehabilitation - West Segment This project is currently under evaluation at the EIR level with project-specific vegetation mapping, wetlands delineation, and focused sensitive species surveys. The project has the potential to affect coastal sage scrub, coastal salt marsh, intertidal habitat, California gnatcatcher, and an existing hardline conservation area. Recommended focused surveys July 2003 3 1 94-04 4.3-17 Carlsbad Water and Sewer Master Plan Updates Program EIR PmfrsriDnal Tiom for Complu Pmlrcti 4.3 Biological Resources to be included in the EIR evaluation include proj ect-level vegetation mapping, wetlands delineation, California gnatcatcher, potential sensitive shorebird species assessment, and spring rare plant surveys. Component 3 - North Agua Hedionda Interceptor Rehabilitation - East Segment This project component has also undergone project-specific evaluation. In mid-2003, the City filed a Notice of Exemption for this project. By design, the construction methods are to avoid all impacts to sensitive biological resources. As part OF the Exemption, CDFG issued a set of conditions that must be met during the construction phase. Component 4 - North Agua Hedionda Trunk Sewer This project involves construction OF 5,000 Feet OF gravity sewer pipeline adjacent to coastal sage scrub supporting California gnatcatcher. The adjacent habitat areas also contain standards and existing hardline conservation designations. As such, the project should be evaluated with Focused surveys including project-level vegetation mapping and California gnatcatcher. Component 5 - North Batiquitos Interceptor Rehabilitation This interceptor sewer would be located on the north shore OF Batiquitos Lagoon where existing mapped resources include coastal sage scrub, maritime succulent scrub, eucalyptus woodland, CaliFornia gnatcatcher, Belding’s savannah sparrow, California least tern, western snowy plover, CaliFornia adolphia, and wart-stemmed ceanothus. In addition, the lagoon habitat is designated as an existing hardline conservation area. Recommended focused surveys include proj ect-level vegetation mapping, wetlands delineation, California gnatcatcher, potential sensitive shorebird species assessment, and spring rare plant surveys. Component 9 - Home Plant Lift Station This lift station is located in a developed area but is adjacent to coastal sage scrub within an existing hardline conservation area. Although no sensitive species are known From this area, recommended focused surveys include project-level vegetation mapping and potential sensitive species assessment. Component 70 - La Costa Meadows Sewer Extension - This lift station removal and installation of 600 feet of gravity sewer occurs in an area July 2003 31 94-04 Carlsbad Water and Sewer Master Pian Updates * Program EIR 4.3-1 8 - PmfcrslaMl Tcomr im Campla Rorrcu 4.3 Biological Resources supporting coastal sage scrub habitat. Although it appears that the sewer can be constructed in the El Fuerte Street right-of-way, the street is surrounded by coastal sage scrub with recorded sensitive species including San Diego thorn-mint and orange-throated whiptail and an existing hardline designation. As such the project should be evaluated for potential direct and indirect impacts utilizing project-level vegetation mapping, California gnatcatcher, and spring rare plant surveys. Component 7 3 - Various Sewer Line Refurbishment/Replacement Implementation of these project components shall be conducted such that each proposed work area is adequately evaluated for potential sensitive habitat and species occurrence prior to initiation of work. Methods for impact avoidance and reduction shall be implemented during refurbishment and replacement procedures. These avoidance and impact reducing measures may include hand clearing of vegetation to stumps versus mechanical clearing for access, application of erosion control measures utilizing native seed mixes or existing biomass, and general employee training and awareness of sensitive biological resources. Component I4 - Vista/Carlsbad Interceptor Reaches VC 7 and VC2 This project includes the rehabilitation of over 9,000 feet of pipeline and 25 manholes. The pipeline currently transverses coastal sage scrub and riparian scrub habitat along Buena Vista Lagoon. Known sensitive species in this area include California gnatcatcher, least Bell’s vireo, and various raptor species. The lagoon is mainly within an existing hardline conservation area, but standards areas are also designated along the sewer alignment. Recommended focused surveys include project-level vegetation mapping, wetlands delineation, California gnatcatcher, least Bell’s vireo, and spring rare plant surveys . Component 7 6 - Vancouver Lift Station This project component includes removal of an existing lift station and construction of 300 feet of gravity sewer. The project appears to only affect annual non-native grassland within a standards area. No sensitive species are recorded from this area. Recommended focused surveys include project-level vegetation mapping and potential sensitive species assessment. - Component 22 - North Batiquitos Lift Station July 2003 3 1 94-04 4.3-1 9 - Carlsbad Water and Sewer Master Plan Updates Program EIR Pmfrsm~I Teanu fm Complex Piaim- 4.3 Biological Resources The lift station is located away from the riparian and tidal portions of the Batiquitos Lagoon but is in an area where coastal sage scrub and annual non-native grassland are mapped. The area is within an existing hardline conservation area and is known to support California gnatcatcher. As such, recommended focused surveys include project- level vegetation mapping, California gnatcatcher, and spring rare plant surveys. Component 23 - Carlsbad Trunk Sewer This proposed 2,000-foot pipeline may affect southern mixed chaparral and coastal sage scrub within existing hardline and standards areas. California gnatcatcher and California adolphia are known to exist in this location. Recommended focused surveys include project-level vegetation mapping, California gnatcatcher, and spring rare plant surveys. Component 28 - Vista/Carlsbad Interceptor Reaches VC3 This sewer line runs along the southern edge of Buena Vista Lagoon and as such has the potential to impact coastal sage scrub and riparian scrub supporting California gnatcatcher. The line also transverses existing hardline conservation areas. Recommended focused surveys include project-level vegetation mapping, California gnatcatcher, and spring rare plant surveys. Component 29 - Buena Vista Lift Station Upgrade This lift station is located on the southeast shore of Buena Vista Lagoon. Adjacent resources include freshwater marsh and mapped localities of California least tern, light- footed clapper rail, several raptor species, and California gnatcatcher. This area is also designated as an existing hardline conservation area. Recommended focused surveys include project-level vegetation mapping, wetlands delineation, California gnatcatcher, potential sensitive shorebird species assessment, and spring rare plant surveys. Component 30 - Buena Vista Lift Station Forcemain This project component is located within the same area as Component 29 described above. As such recommended focused surveys are the same and include project-level vegetation mapping, wetlands delineation, California gnatcatcher, potential sensitive shorebird species assessment, and spring rare plant surveys.

Existing habitats in this area include coastal sage scrub, coastal salt marsh, and eucalyptus woodland. No sensitive species are recorded for this area; however, it is within an existing hardline conservation area. Recommended focused surveys include project- level vegetation mapping, wetlands delineation, California gnatcatcher, potential sensitive shorebird species assessment, and spring rare plant surveys. 4.3.4 Mitigation Measures The 26 project components found to have a potentially significant impact to biological resources require mitigation measures. The determination of final mitigation for each project component shall first consider the project design features identified in Table 2-5. htigation would then follow the guidelines discussed below but also shall be based on project-level resource evaluation. The project-level evaluation would be more detailed and may result in a finding of no significant impact, and in that event, would not require mitigation. However, at this program level of analysis, each of the components identified as having a significant impact to biological resources would require mitigation. Following proj ect-level resource mapping and identification of precise implementation methods and location, significant adverse impacts to biological resources can generally be avoided or mitigated through incorporation of one or all of the following measures: 0 Avoidance and minimization of impacts through project redesign or implementation of construction restrictions including seasonal restrictions (these measures would likely need to be ensured through construction monitoring adjacent to sensitive resource areas); 0 Conservation of like habitat near to project impact area through dedication of a conservation easement and management endowment; and/or Enhancement, restoration, and/or creation of habitats affected by the project with methodologies approved by the City and resource agencies. Project impacts and resultant mitigation requirements will be evaluated under CEQA, the Porter-Cologne Act, federal Clean Water Act, the California Fish and Game Code, the state and federal Endangered Species Acts, and the Natural Communities Conservation Act. Impacts to jurisdictional wetlands are regulated by two state agencies and one federal 3 1 94-04 4.3-21 July 2003 Carlsbad Water and Sewer Master Plan Updates - Program EIR Profcuionnl Bans for Complu Prolecv 4.3 Biological Resources agency: the Regional Water Quality Control Board (RWQCB), CDFG, and ACOE, respectively. Authorization OF impacts to jurisdictional wetlands occurs through issuance of a Section 401 Water Quality CertiFication and/or Waste Discharge Requirement by RWQCB, Streambed Alternation Agreement by CDFG, and Section 404 Nationwide or Individual Permit by ACOE. Each OF these agencies implement a policy OF “no net loss” OF jurisdictional wetlands and thereFore require that all permanent impacts be mitigated through the creation OF lke habitat at a ratio OF at least 1:l. Impacts are often mitigated through a combination OF wetlands creation and enhancement at a combined ratio between 2:l and 5:l depending on the rarity or sensitivity of the habitat as well as temporal loss. Currently, Take Authorization For listed species proposed For coverage under the Carlsbad HMP has not been issued, therefore projects which may impact any state or federally listed species must obtain permit authorization From the resource agencies. The permit authorization may occur through Section 4(d), Section 7, or Section 10(a) by USFWS, or Section 2080.1 or 2081 by CDFG. Section 4(d) is reserved For impacts to coastal sage scrub under the Interim Habitat Loss Permit guidelines. These guidelines allow For take OF five percent OF coastal sage scrub habitat From the time OF NCCP enrollment until Take Authorization is granted through an approved Subarea Plan (Le., HMP). Section 7 is the authorization mechanism where another Federal agency is involved in the project. Typically this agency is the ACOE. Section 10(a) is employed when authorization is granted through a Habitat Conservation Plan (HCP) For the aFfected species. In cases where the species afFected is both state and federally listed, CDFG is consulted throughout the process but only issues a 2081 Consistency Determination. IF the species is only state listed, CDFG must issue a 2080.1 take authorization. Take Authorization thresholds are diFFerent For the various permit methods described above, but generally involve the avoidance and minimization OF impacts and mitigation For unavoidable impacts. For most species, mitigation occurs in the Form OF habitat conservation and/or restoration (where temporary impacts would occur). This habitat conservation must be like habitat supporting an equal or greater number OF species than that impacted by the project. Any Take Authorization will likely include evaluation of the project in the context of the proposed HMP such that implementation OF the project does not preclude assemblage of the reserve. Once Take Authorization has been issued for the HMP, impacts to covered species may be permitted without consultation OF the resource agencies. The HMP may contain conditional coverage for species and therefore the project would need to be evaluated under the conditions to determine if take is in Fact authorized. These conditions may July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates. Program EIR 4.3-22 4.3 Biological Resources include whether or not the species’ locality subject to impacts is within or outside a designated conservation area, whether specific siting criteria have been implemented to reduce potential impacts, and whether seasonal avoidance is being proposed. Although take may be authorized by the HMP, mitigation may still be required on a project-level basis. This mitigation will likely involve dedication of open space within the identified reserve area and/or enhancement of habitats within the reserve. 4.3.5 Residual Impact After Mitigation Implementation o€ the suggested mitigation measures would reduce impacts to less than significant.

Prqertr 4.4 Cu I tu ra I Resources 4.4 CULTURAL RESOURCES The purpose of this cultural resource section is to assess general cultural resource conditions and identify potential cultural resources within the vicinity of water and sewer master plan components. Paleontological resources are also addressed. The cultural resource information used in this analysis is from the May 2003 City of Curlsbud Water and Sewer Muster Plans Cultural Resource Buckground Study prepared by Gallegos and Associates for this Program EIR (Appendix B). Detailed references to specific previous studies used to prepare the Cultural Resources Study can be found in that appendix. Cultural resource field reconnaissance work was not performed For each master plan component as part o€ this Program EIR. The Cultural Resources Study included archaeological record and data review of the project areas to determine the recorded patterns of cultural resources within the study area boundaries. From this information and current aerial photographs of the project locations, assessments could be made regarding the potential for cultural resources within the general vicinity of pipelines and Facilities. This information also indicated where existing development has precluded the possibility of any cultural resources. A record search was conducted at the South Coastal Information Center at San Diego State University and Gallegos & Associates library. The record searches principally focused on the locational information for recorded sites. The data from the Information Center was transferred onto the project maps to assess possible conflicts with proposed master plan components. The data was also compared to the project aerial photograph series to determine where recorded archaeological sites were destroyed by previous development. No surveys were conducted for this Program EIR, principally due to the number of projects and miles of project components. As such, this section will identify those project components that would require additional cultural resource investigation when more detailed project design information becomes available. 4.4.1 Existing Conditions/Setting Cultural Resources The City of Carlsbad has a very rich and extensive record of prehistoric activity. A summary of the historic setting of previous populations is presented below; Appendix B contains a complete description of the historic setting, as well as a complete set of references cited in this section. July 2003 31 94-04 4.4-1 Carlsbad Water and Sewer Master Plan Updates Program EIR Profetrtrmol Team for Complu Proiccu 4.4 Cultural Resources Background - Prehistory The body of current research of prehistoric occupation in San Diego County recognizes the existence of at least two major cultural traditions, discussed here as Early Period/Archaic and Late Period, based upon general economic trends and material culture. Within San Diego County, the Archaic generally spans the period from 10,000 to 1300 years ago, while the Late Period spans from 1300 years ago to historic contact. The Historic Period covers the time from Spanish contact to present. Early Period/Archaic The Early Period/Archaic, for this discussion, includes the San Dieguito and La Jolla complexes, which are poorly defined, as are the interrelationship between contemporaneous inland, desert, and coastal assemblages (Gallegos 1987). Initially believed to represent big game hunters, the San Dieguito are better typified as a hunting and gathering society. These people had a relatively diverse and non-specialized economy in which relatively mobile bands accessed and used a wide range of plant, animal, and lithic resources. Movement of early groups into San Diego County may have been spurred by the gradual desiccation of the vast pluvial lake system that dominated inland basins and valleys during the last altithermal period. This hypothesis is supported by the similarity between Great Basin assemblages and those of early Holocene Archaic sites in San Diego County. Several researchers recognized the regional similarity of artifacts and grouped these contemporaneous complexes under the nomenclature of either the Western Pluvial Lakes Tradition or the Western Lithic Co-tradition (Bedwell 1970; Davis et al. 1969; Rogers 1939; Warren 1967; Moratto 1984). The origin of coastal populations and subsequent interaction between the coastal population and Great Basiddesert groups is a subject of some debate (Gallegos 1987). Whatever their origin, the first occupants immediately exploited the coastal and inland resources of plants, animals, shellfish, and fish (Moriarty 1967; Kaldenberg 1982; Gallegos 1991; Kyle et al. 1998). The development of a generalized economic system indicates that the San Dieguito and related groups can be placed within the general Archaic pattern. Archaic cultures occur within North America at slightly different times in different areas, but are generally correlated with local economic specialization growing out of the earlier Paleo-Indian Tradition (Willig, Aikens and Fagan1988). Archaic cultures are often represented by more diverse artifact assemblages and more complex regional variation than occur in Paleo- I July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.4-2 _- 4.4 Cui t u ral Resources Indian traditions. This is generally thought to have resulted from the gradual shift away from a herd-based hunting focus to a more diverse and area specific economy. The earliest sites are found near coastal lagoons and river valleys of San Diego County. These sites are the Harris Site (CA-SDI-149), Agua Hedionda Sites (CA-SDI-210/UCLJ-M- 15 and CA-SDI-10695), Rancho Park North (CA-SDI-4392/SDM-W-49), and Remington Hills (CA-SDI-11069), dating from 9500 to 8000 years B.P. The northern San Diego County coastal lagoons supported large populations, circa 6000 years ago, as shown by the numerous radiocarbon dated sites adjacent to these lagoons. After 3000 years ago, there is a general absence of archaeological sites in north San Diego County to circa 1500 years ago. This reduction in number of archaeological sites can be attributed to the siltation of coastal lagoons and depletion o€ shellfish and other lagoon resources (Warren and Pavesic 1963; Miller 1966; Gallegos 1985). Archaeological sites dated to circa 2000 years ago are €ound closer to San Diego Bay, where shellfish were still abundant and may well represent what can be considered the end of the La Jolla Complex (Gallegos and Kyle 1988). The La Jolla and Pauma complexes, which are identified as following the San Dieguito Complex, may simply represent seasonal or geographic variations of the somewhat older and more general San Dieguito Complex. Inland La Jolla occupation sites have been reported in transverse valleys and sheltered canyons (True 1959; Warren et al. 1961; Meighan 1954). These non-coastal sites were termed “Pauma Complex” by True (1959), Warren et al. (1961), and Meighan (1954). Pauma Complex sites by definition have a predominance of grinding implements (manos and metates), lack shellfish remains, have greater tool variety, seem to express a more sedentary occupation, and have an emphasis on both gathering and hunting (True 1959; Warren 1961; Meighan 1954). Archaic sites from 10,000 to 1300 years ago within San Diego County include coastal habitation sites, inland hunting and milling camps, and lithic quarry sites. Material cultural assemblages during this long period are remarkably similar in many respects. These deposits may well represent a process of relative terrestrial economic stability and presumably slow cultural change. Though various culture traits developed or disappeared during the long span of 10,000 to 1300 years ago, there is a clear pattern of cultural continuity during this period. Late Period During the Late Period (circa 1300 to historic contact), a material culture pattern similar to that of historic Native Americans first becomes apparent in the archaeological record. The economic pattern during this period appears to be one of more intensive and efficient July 2003 31 94-04 4 4-3 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.4 Cultural Resources exploitation OF local resources. The prosperity OF these highly refined economic patterns is well evidenced by the numerous Kumeyaay/Dieguefio and Luiseiio habitation sites scattered over San Diego County. This increase in Late Period site density probably reFlects better preservation OF the more recent archaeological record and a gradual population increase within the region. ArtiFacts and cultural patterns reflecting this Late Prehistoric pattern include small projectile points, pottery, the establishment of permanent or semi-permanent seasonal village sites, a proliFeration OF acorn milling sites in the uplands, the appearance of obsidian From Obsidian Butte, and interment by cremation. Many of the Late Prehistoric culture patterns in southern CaliFornia were shared with groups along the eastern periphery OF the region. Even in the most recent periods, the Native Americans of southern California incorporated many elements OF their neighbors’ culture into their own cultures. This transFerence and melding of cultural traits between neighboring groups makes positive associations OF archaeological deposits with particular ethnographically known cultures difficult. This is particularly true of the groups within San Diego County. Though significant differences exist between Luisefio and Kumeyaay/Dieguefio cultures (including linguistic stock), the long interaction OF these groups during the Late Period resulted in the exchange OF many social patterns. Archaeologists must rely heavily on ethnographic accounts OF group boundaries as recorded during the historic period, although it is not known how long these boundaries had been in place or the validity OF these boundaries as presently reported. The project area Falls within Luiseiio territory as defined by Kroeber (1925). As a result OF contact with Spanish, Mexican and American settlers, Native American populations were decimated by resettlement and disease. Presently, Native Americans are found throughout San Diego County, especially within the 17 San Diego County reservations. Historical Background An abbreviated history OF Spanish, Mexican and American settlement in San Diego County is presented, taken from Gallegos et al. 1993, for the purpose OF providing a background For discussion OF the presence, chronological significance and historical relationship OF historical resources within the project area. The history OF San Diego County is commonly presented in terms OF Spanish, Mexican and American political domination. A discussion OF historic land use and occupation under periods of political rule by people of European and Mexican origin is justiFied on the basis OF characteristics associated with each period, when economic, political and social activities were inFluenced July 2003 3 1 94-04 4 4-4 Carlsbad Water and Sewer Master Plan Updates Program EIR Prafruio~l Timu fm Compk Project. 4.4 Cult u ra I Resources by the prevailing laws and customs. Certain themes are common to all periods, such as the development of transportation, settlement, and agriculture. Robinson (1979) provides a comprehensive account of public and privately owned land in California, with a discussion of laws, activities and events related to the development of the State. Spanish Period (7 769- 7 82 7) The Spanish Period represents: exploration; establishment of the San Diego Presidio, and the San Diego and San Luis Rey missions; the introduction of horses, cattle, and agricultural goods; and, a new method of building construction and architectural style. Spanish influence continued after 1821, when California became a part of Mexico. Under Mexican rule, the missions continued to operate as in the past, and laws governing the distribution of land were also retained for a period of time. Mexican Period (7 82 7 - 7 848) The Mexican Period includes the initial retention of Spanish laws and practices until shortly before secularization of the San Diego fission in 1834, a decade after Spanish rule. Although several grants of land were made prior to 1834, vast tracts of land were dispersed through land grants offered after secularization. Cattle ranching prevailed over agricultural activities and the development of the hide and tallow trade increased during the early part of this period. The Pueblo of San Diego was established and transportation routes were expanded. The Mexican Period ended as a result of the Mexican-American War. American Period (7848 to Present) The American Period began when Mexico ceded California to the United States under the Treaty of Guadalupe Hidalgo. Terms of the treaty brought about creation of the Lands Commission, in response to the Homestead Act of 1851, that was adopted as a means of validating land ownership throughout the state through settlement of land claims. Few Mexican ranchos remained intact because of legal costs and lack of sufficient evidence to prove title claims. Much of the land that once constituted rancho holdings became available for settlement by immigrants to California. The influx of people to California and the San Diego region was the result of various factors, including the discovery of gold in the state; the conclusion of the Civil War; the availability of free land through passage of the Homestead Act; and, later, the importance of the county as an agricultural area supported by roads, irrigation systems, and connecting railways. The growth and decline July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.4-5 4.4 Cultural Resources OF towns occurred in response to an increased population and the economic boom and bust cycle in the late 1800s. Paleontological Resources The Following discussion presents those rock Formations considered high to moderately sensitive in paleontological resources. Unnamed Pleistocene Terrace Deposits The Coastal Plain Province OF San Diego County is characterized by a “stair-step” sequence OF elevated marine terraces (uplifted sea floors) and associated marine and non- marine sedimentary covers. These deposits show a direct correlation between elevation and geologic age; the lowest terraces are the youngest, and the highest terraces are the oldest. These deposits consist primarily of poorly indurated claystones and Friable sandstones which Form a sedimentary veneer. The unnamed Pleistocene terrace deposits often consist OF a basal nearshore marine stratigraphic unit and an upper non-marine stratigraphic unit. The basal unit has produced large and diverse assemblages OF marine invertebrate Fossils such as mollusks, crustaceans, and echinoids as well as sparse remains OF marine vertebrates such as sharks, rays, and bony Fish. The upper unit has produced sparse remains OF terrestrial mammals such as camel, horse, and mammoth. It is unclear whether the terrace deposits represent nearshore marine or non-marine units discussed above. In either case, no Fossils are reported From these exposed terrace deposits. Based on the sedimentary origin of these deposits and the published fossil record, they are assigned a moderate resource sensitivity. Unnamed Pleistocene Lagoonal Deposifs This interbedded unit OF poorly consolidated dark-gray claystone, siltstones, and clayey sandstones underlies the unnamed Pleistocene terrace deposits. These deposits have a patchy distribution. Estuarine mollusks have been reported From Pleistocene lagoonal deposits occurring in the north San Diego County region. Geotechnical testing resulted in the discovery OF Fossil plant material in these lagoonal deposits. The recovery of leaves of terrestrial plants and shells OF estuarine mollusks From these deposits suggests a moderate resource sensitivity rating. - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4 4-6 - Pmfrrria~l Tern (m Caplcr Pml~cu 4.4 Cultural Resources Sanfiago Formation fiddle Eocene sedimentary rocks in north San Diego County have been assigned to.the Santiago Formation, with three members (“A,” “B” and “C”) recognized in the Encinitas- Oceanside area. Member “B” of the Santiago Formation consists largely of green and gray, very fine- to medium-grained, arkosic sandstone, with common calcite-cemented concretions and frequent interbed of multi-colored clayey sandstone and claystone. Member “B” of the Santiago Formation has produced well-preserved vertebrate fossils from numerous localities in Carlsbad and Oceanside including snakes, turtles, opossums, insectivores, bats, primates, rodents, carnivores, tapirs, brontotheres, rhinoceros, uintathere, protoreodonts, leptoreodonts, and oromerycid artiodatyls. The mammalian fauna is especially significant as it contains a mosaic of archaic and advanced species, and serves to document an important period in mammal evolutionary history. Also recovered from Member “B” deposits are the remains of various types of marine and estuarine mollusks. Fossils of terrestrial vertebrates have been found in the Santiago Formation which include the remains of extinct rhinoceros, carnivores, tortoise, brontothere, tapirs, and rodents. To the west, this formation grades upward into a shallow marine environment containing fossil clams, snails, sea urchins, sharks, and batray teeth. Member “B” of the Santiago Eormation is assigned a high paleontological resource sensitivity. 4.4.2 Significance Criteria The project components would have a significant effect related to cultural resources/paleontology if it would: Cause a substantial adverse change in the significance of a historical resource as defined in CEaA Guidelines 515064.5; Cause a substantial adverse change in the significance of an archeological resource pursuant to CEQA Guidelines $15064.5; Disturb any human remains, including those interred outside of formal cemeteries; or July 2003 31 94-04 4 4-7 Carlsbad Water and Sewer Master Plan Updates Program EIR Pmferiiml Tenmu fm Complol RopU 4.4 Cultural Resources Water Project Site Type Component Number Site Number Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature. Condition 4.4.3 Impact Analysis Cul tu ra I Resources The literature review and record search identified 87 previously prepared cultural resource studies conducted within or immediately adjacent to the project study area. Based on these studies, a total o€ 63 cultural resource sites have been identified within the study area. Of the 63 sites, 9 sites were identified as not significant, 4 sites were identified as significant, 48 sites were identified as unknown site status, and 2 sites were identified as unknown site status for portions of the site. Of the 63 sites, a total of 33 sites have been recorded within the Water Master Plan Update study area, and a total of 34 sites have been recorded within the Sewer Master Plan Update study area. Data gaps include the unevenness of the archaeological record and varied quality of the previously recorded cultural resource database. A list of the known cultural resource sites that would be potentially affected by various project components in the proposed Master Plan Updates are identified in Tubles 4.4-JI and 4.4-2 below. As such, the project components listed in the tables below have the potential to result in significant impacts to cultural resources. Detailed information on each of these sites is available in Appendix B of this EIR. In addition, Tubles S-4 and S-2 summarize the cultural resource impacts and mitigation €or each project component within the proposed Master Plan Updates.

Specific locations of potential impact would be those locations considered to be high- to moderately sensitive in paleontological resources. It should be noted that specific information would become available at the time of grading. Construction of new facilities may disturb fossil-bearing geological strata in almost any location in the city. Pipelines are generally constructed in road rights-of -way or existing easements where strata have already been disturbed, so that the potential for intact fossils representing signifcant paleontological in€ormation is low. The same condition will prevail at sites of lift stations, reservoirs, and pump stations where prior construction has extensively disturbed the underlying earth materials. 4.4.4 Mitigation Measures Cultural Resources Survey, testing, and mitigation programs (where necessary) are recommended for the cultural resources sites with undetermined site status and are based on CEaA and City of Carlsbad Guidelines. For undeveloped lands, these consist of the project components July 2003 3194-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.4-12 Profenionnl Teomr fm Camplor Rorer~ 4.4 Cultural Resources which have not been previously surveyed, and due to the high sensitivity of prehistoric sites near lagoons, all project components within one-half mile of a lagoon. For all sites located within undeveloped land, surface collections should be used to determine the site limits and areas of artifact concentrations in order to ascertain placement of test units and shovel test pits (STPs) and/or backhoe trenches. Excavation units (1 x lm) should be those areas where ground stone, fire-altered rock, or a concentration of flaked material occur. Backhoe trenching is recommended at those sites where deep subsurface deposits (i.e., historic privies or dumps or subsurface prehistoric deposits) are possible. For all sites located within developed land, a monitoring program is recommended during construction. Monitoring is recommended for sites that have been previously addressed as to mitigation of impacts through a data recovery program, as additional unknown buried deposits may still be present. For the historic sites, the test program should include a literature/historic files review, mapping of any remaining structures, and mechanical backhoe trenching when applicable for determining the location of historic dumps. fitigation through data recovery and all reports should follow City of Carlsbad Guidelines (1980). The following recommended mitigation measures would reduce impacts identified above in Section 4.4.3 to less than significant. 1. 2. 3. 4. Obtain permission from private landowners to survey the fields and yards in order to determine presence/absence of cultural resources. If cultural resources are located then mitigation measure [2] is recommended. Test those sites that have not yet been tested so a determination of significance can be made. If the resource is determined to be significant, mitigate through avoidance. If avoidance is not feasible, then mitigation through a data recovery program (see mitigation measure [3]). If site avoidance, the preferred mitigation measure, is not feasible, then a data recovery program should be completed to recover a large enough sample of cultural material so that information of importance in addressing regional research questions will not be irretrievable lost through impacts. Provide a qualified archaeological monitor during construction so that buried cultural resources can be identified in the field. Upon identification, the resource should be tested (mitigation measure [2]) to determine significance with appropriate mitigation measures as necessary. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.4-13 4-4 Cultural Resources Monitoring Program An additional mitigation measure is intended For many sites within the study area that are located within developed areas. For these sites, a monitoring program, rather than a test program, is recommended iF construction is to occur within or adjacent to the site.

Paleontological Resources 1. Projects that may impact paleontologically sensitive areas (Le., formations that have been assigned high or moderate paleontological resource sensitivity), will require paleontological monitoring onsite during all phases of initial and subsequent cutting of undisturbed formational sediments in order to make salvage collections of any invertebrate, vertebrate or paleobotanical fossils that are encountered or unearthed. 2. Collected fossils shall be cleaned and/or prepared to a point of identification, and then curated to museum standards (cataloging of locality and specimen data, numbering, identification, labeling) before being deposited in an appropriate public facility (or facilities) that can provide permanent archival storage (so that specimens are available for future scientific study). A report detailing the mitigation shall be prepared, even if negative, which will include necessary maps, graphics, and fossil lists to document the paleontological monitoring program. 3. Paleontological monitoring will be required for all exposures of the Santiago Formation and of Pleistocene marine terrace and estuarine deposits. A museum collections and records search will precede any field work, in order to more precisely define any areas that might need particular attention during monitoring of construction related activities. Monitoring is not necessary in areas mapped as granitic (tonalite, gabbro) or metavolcanic rock. 4. These general guidelines shall be followed when planning for a project component which requires paleontological monitoring: a. The paleontologist or paleontological monitor shall attend any preconstruction/pregrading meetings to consult with City/District staff and the excavation contractor. 31 94-04 July 2003 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4 4-20 c c c 4.4 Cultural Resources b. The paleontologist or paleontological monitor shall be onsite full-time during excavation into previously undisturbed formations. The monitoring time may be decreased at the discretion of the paleontologist in consultation with the City/District. c. If significant fossils are encountered, the paleontologist shall have the authority to divert or temporarily halt construction activities in the area of discovery to allow recovery of fossil remains, and shall immediately contact the City/District. The determination of significance shall be at the discretion of the paleontologist. d. Construction activities in the area of discovery shall resume upon notification by the paleontologist that fossil remains have been recovered. The paleontologist shall be responsible for preparation of fossils to a point of identification and submittal of a letter of acceptance from a local qualified curation facility. The paleontologist shall record any discovered fossil sites at the San Diego Natural History Museum. e. Within three months foIIowing termination of the paleontological monitoring program, the contractor shall provide a monitoring letter report (with appropriate graphics) to the City/District summarizing the results (even if negative), analyses and conclusions of the above program. 4.4.5 Residual Impacts after Mitigation Cultural Resources. With the implementation of the mitigation measures identified in Section 4.4.4, impacts would be reduced to less than significant. Paleontological Resources. identified in Section 4.4.4, impacts would be reduced to less than significant. With the implementation of the mitigation measures July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.4-21 4.5 Geology and Soils 4.5 GEOLOGY AND SOILS The purpose of this section is to assess general geologic conditions and identify potential geologic impacts, geotechnical hazards, and effects to mineral resources in the project areas. The information used in this analysis is general in nature and is derived from the most readily available information found in applicable resource and planning documents. Site-specific geotechnical analyses were not performed for the project areas. General geologic and soil resource conditions were researched through the use of reports and data produced by the California Department of Conservation (DOC), the California Geological Survey (CGS, formerly the Division of Mines and Geology), San Diego State University Geology Department, the City General Plan (1994) and associated General Plan Master EIR (1994), the City and County of San Diego online geographical database (www.SanGIS.org), and the U.S. Department of Agriculture Natural Resource Conservation Service (NRCS, formerly the Soil Conservation Service). A complete listing of these references is included in Chapter 9.0. 4.5.1 Existing Conditions Soils The study area contains seven general soil associations as indicated by the San Diego County Soil Survey (1996). Soils associations are useful for developing a general idea of the soils in an area and for determining the value of an area for certain uses. The following discussion outlines these soil classifications. 1. Marina-Chesterton Association: This association consists of somewhat excessively drained to moderately well drained loamy coarse sands and fine sandy loams that have a subsoil of sandy clay over a hardpan. This soil type is located between sea level and 400 feet above mean sea level and occurs on grades of 2 to 15 percent (NRCS 1973). 2. Salinas-Corralitos Association: This consists of moderately well-drained to somewhat excessively drained clays, clay loams, and loamy sands on alluvial fans, on 0 to 9 percent slopes. 3. Cieneba-Fallbrook Association (Very Rocky) : These soils are excessively drained to well-drained coarse sandy loams and sandy loams that have a sandy clay July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.5-1 ProferszawI Temm fov Complex Rqec~ 4.5 Geology and Soils loam subsoil over decomposed granodiorite. These soils occur between 200 and 3,000 Feet above mean sea level and occur on 9 to 75 percent slopes. 4. Exchequer-San Miguel Association: Rocky, well drained silt loams over metavolcanic rock, typically on 0 to 30 percent slopes. 5. Diablo-Altamont Association: Well drained clays are the major characteristic OF this association, normally Found on 5 to 15 percent slopes. 6. Diablo-Las Flores Association: This association consists OF well drained clays and moderately well drained loamy Fine sands that have a subsoil OF sandy clay. These soils occur between 100 and 600 Feet above mean sea level and occur on 9 to 30 percent slopes (NRCS 1973). 7. Las Flores-Huerhuero Association: This association consists OF moderately well-drained loamy Fine sands to loams that have a subsoil OF sandy clay or clay; 9 to 30 percent slopes. Faults and Seismic Hazards The study area For the Master Plans is located within seismically active southern CaliFornia. Although this region in known to be akin to seismic events, there are no known Faults within the area, and no Alquist- Priolo Special Study Zones have been identiFied (City OF Carlsbad 1994). The primary OFF-shore Faults include the Coronado Bank, San Diego Trough and San Clemente systems. The main Fault system in western San Diego County is the Rose Canyon Fault which originates in Mission Bay, drops OFF into the Pacific Ocean at La Jolla Shores and then runs north along the coast to Oceanside. Several smaller faults exist on the San Diego Mesa, largely within the City OF San Diego. These faults include the Texas Street Fault, the Fortieth Street Fault, the La Nacion Fault and the Florida Canyon Fault. Regional fault systems, including the San Jacinto, San Andreas and Elsinore Faults are located to the east and north of the study area (Kern 1989). Liquefaction and dynamic settlement OF soils can be caused by strong vibratory motion resulting From seismic activity. Research and historical data indicate that loose, granular soils are susceptible to these eFFects, while the stability OF most silty clay and clay soils is not adversely aFFect by vibratory motion. Among granular soils, finer textured varieties are most susceptible to liquefaction than coarse-grained types, and soils OF uniForm grain size are more likely to liquefy than well-graded materials. There are limited areas in the July 2003 31 94-04 4.5-2 Carlsbad Water and Sewer Master Plan Updates Program EIR PmfmrlowI Team fm Complp ROJLCU 4.5 Geolow and Soils City which are considered potentially subject to liquefaction, including areas west of El Camino Real, the areas in and around lagoons, and along the beaches (City of Carlsbad 1994). Mineral Resources - The Surface Mining and Reclamation Act of 1975 requires the State Board of Mining and mineral deposits of statewide or of regional significance. The process involves classification and designation. Classification inventories select mineral commodities within a defined study area. These are areas where adequate information indicates that significant mineral deposits are present or where it is judged that a high likelihood for their presence exists. Designation identifies deposits of regional or statewide significance which are available from a land use perspective. The CGS characterizes mineral potential according to their Mineral Resource Zone (MU) categories. Areas classified as MRZ-1 are considered to have little likelihood of containing significant deposits suitable for production as high-quality aggregate. Areas classified as MRZ-2 have a high likelihood that significant deposits of PCC grade aggregate exist. Areas classified as MRZ-3 are areas containing aggregate deposits, the significance of which cannot be evaluated from existing data or available information. And finally, MU-4 denotes areas where not enough information is known to determine if mineral deposits are present or if they are significant. These areas do not fit into any other MRZ zone (CGS 1996). Geology and the State Geologist to prepare mineral resource reports that designate - - The majority of the project study area is located in a MRZ-3 zone (CGS 1996). Also, a portion of the study area immediately south of SR78/College Boulevard intersection that extends toward Lake Calavera, is designated as MRZ-2. This zone consists of the South Coast Materials Company Carlsbad Quarry. This MRZ-2 zone indicates the presence of significant mineral deposits or the high likelihood that they exist. Mmeral resources within the City of Carlsbad are no longer being extracted and utilized as exploitable natural resources. There are several abandoned gravel pit operations within City limits, and two abandoned salt evaporation ponds; one is near the south shore of the Buena Vista Lagoon and the other one is north of La Costa Avenue near the eastern perimeter of the Batiquitos Lagoon (City of Carlsbad 1994). 4.5.2 Significance Criteria The project components would have a significant effect related to geology and soils if it would: July 2003 31 94-04 4.5-3 4.5 Geology and Soils Expose people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving: (i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault (based on the Division of Mines and Geology Special Publication 42); (ii) Strong seismic ground shaking; (iii) Seismic-related ground failure, including liquefaction; or (iv) Landslides; Result in substantial soil erosion or the loss of topsoil; Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or oFf-site landslide, lateral spreading, subsidence, liquefaction, or collapse; Be located on expansive soils, as defined in Table 18 - 1-B of the Uniform Building Code (1994), creating substantial risks to life or property; Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater; Result in the loss of availability of a known mineral resource that would be of future value to the region and the residents of the State; or Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan. July 2003 31 94-04 4.5-4 Carlsbad Water and Sewer Master Plan Updates Program EIR Geology and Soils 4.5.3 Impact Analysis At this program level of analysis, the actual level of impact cannot be determined. That is, project components would require site-specific geotechnical studies for engineering and design, which would determine the actual level of environmental impact. These future geotechnical investigations will describe site-specific conditions and suggest mitigation measures for the issues outlined in this Program EIR section. As such, impacts would be presumably reduced to less than significant at the project level once detailed project data can be assessed and mitigation measures are implemented. No unmitigable significant effects are anticipated. More detailed analysis follows. Potentially significant construction-related impacts associated with the Master Plans include encountering unstable soil and rock conditions and exposure of oversize rock material during grading. The design of each project component would be accompanied by a geotechnical evaluation that would indicate if such hazards were present. If the geotechnical study so indicated, the proposed facility site would be relocated to a nonhazardous area. The specific soil types each project component will impact at this time are unknown. Assuming a site-specific geotechnical study is completed, additional information regarding content, expansiveness, stability, potential for subsidence and compactibility will be determined during project planning and design. Appropriate mitigation measures would be incorporated into the design to reduce the potential for significant effects. Also, septic tanks or alternative wastewater disposal methods are not proposed as part of the Master Plans. For this program level of analysis, impacts would be less than significant. During the construction of proposed Master Plan components, erosion could be accelerated which could undermine slopes, create siltation of surface waters, and expose and damage underground facilities. All construction must be performed in accordance with the requirements of the Carlsbad Grading Ordinance, which requires the control of erosion during construction and the stabilization of all disturbed surfaces upon completion of construction. It is not anticipated that the project would result in substantial soil erosion or significant losses of topsoil. July 2003 3 1 94-04 4.5-5 - Carlsbad Water and Sewer Master Plan Updates Program EIR Geolow and Soils Faults and Seismic Hazards The study area is located within seismically active southern California. Master Plan components are not anticipated to traverse known faults associated with the Rose Canyon Fault System. Additionally, due to the project design feature in Table 2-5 which requires that all project components be constructed in accordance with Uniform Building Code requirements related to protection against seismic instability, subsidence and liquefaction hazards and stability impacts would be less than significant. The proposed project components may be locally subject to seismically induced secondary effects related to liquefaction, lateral spreading, local subsidence of soil, and vibrational damage. Pipelines are replaced or rehabilitated typically by trenching and backfill, underground. The pipe is supported on bedding material, and at least six to eight inches of clearance is left between the pipe and trench walls. Suitable granular pipe zone material is placed around and on top of the pipe. Backfill must consist of suitable material, free of organic material, debris, and large rocks. This construction method absorbs energy during seismic events and relieves susceptibility to ground motion that would cause rupture of the pipe. Because of the construction specifications described above, impacts associated with seismic hazard are not considered significant. The two Master Plans include a number of sizable new facilities, pump stations, pressure reducing stations, and reservoirs. City engineering requirements implemented during the planning and design of such facilities require a thorough geotechnical evaluation before final plans are approved. Recommendations for remedial action, if needed, that are identified in the geotechnical report must be implemented by the construction contractor. This process is designed to avoid the potential for significant seismic and geological hazards associated with such facilities. Reservoirs may pose a potential threat to surrounding areas in a seismic event. However, for seismic events of the most common intensities, aboveground reservoirs usually do not rupture but, if ground movement is sufficient, move about as a unit on the building pad. Damage to offsite areas from ruptured reservoirs has been a rare event in southern California in recent decades. Construction of these reservoirs is preceded by a geotechnical study intended to identify the maximum intensity of ground acceleration most likely to occur at a given locality (the “maximum credible event”), and the reservoir is designed to resist damage in such an event. Steel reservoirs are designed to meet the seismic safety standards of the American Water Works Association, and concrete reservoirs are designed to meet the seismic safety standards of the Structural Engineering Association of California. c July 2003 3194-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.5-6 - 4.5 Geology and Soils Mineral Resources No project components are located within designated MRZ-1 or MRZ-2 zones. The South Coast Materials Company Carlsbad Quarry and associated MRZ-2 zone are located east of and away from project components. There would not be impacts to the known aggregate resources associated with the quarry. The remaining components of the Master Plans are all located within MRZ-3 zones. Due to the necessity of perForming a site-specific geotechnical investigation, additional information regarding the unknown content OF MRZ-3 zones will be explored at the time of project-specific detailed planning and engineering studies. Due to the general nature of information available at this program level of analysis, impacts are anticipated to be less than significant. 4.5.4 Mitigation Measures No significant geology and soils impacts have been identified; mitigation measures are not required. 4.5.5 Residual Impact After Mitigation Impacts would be less than significant.

No Environmental Site Assessments (Phase I or 11) were conducted for - - The project has the potential to cause different types of hazards and hazardous materials impacts. These potential hazards include natural hazards such as those associated with development OF a project component in high fire hazard areas. Other potential hazards are related to human activities. These hazards include the potential for leaks or spills o€ raw sewage From pipelines or sewage conveyance Facilities, potential For leaks or spills OF petroleum fuels during construction and operation of the project, and the potential For disturbance of a site containing hazardous materials. The project also has the potential to cause hazards due to its proximity to the McClellan-Palomar Airport in the City of Carlsbad. - Hazardous Materials and Hazardous Material Sites According the City’s General Plan Master EIR (1994)’ approximately 75 percent of registered hazardous substances in the City are located at gas stations and auto-related businesses. All gas station are located on land which is commercially designated on the General Plan. Smaller scale auto service uses such as body shops and repair shops are generally located along State Street. Other small scale uses such as dry cleaners, medical/dental oFFices and veterinary clinics use and produce extremely small quantities of hazardous materials and waste annually and are also distinguished largely through the City’s commercially designated land use areas. The large-scale use of hazardous materials is well defined in the community, and is restricted primarily to industrially allocated land in business parks surrounding the airport and west of 1-5 along Avenida Encinas. The majority of these uses are either related to semi-conductor production or the biotech industry. Additionally, small-scale aviation- related businesses (which may store aviation Fuel) are located near McClellan-Palomar Airport. The only industrial business operating on land without an industrial General Plan designation is the South Coast Asphalt Company on Haymar Road. This business uses quarrying and road surFace materials. - July 2003 3194-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.6-1 - 4.6 Hazards and Hazardous Materials Utilities, such as San Diego Gas and Electric (SDGE) and the Encina WPCF, use some hazardous materials in their operations but they do not directly manufacture or dispose of hazardous materials as their primary purpose. These sites are designated Public Utility on the General Plan and Zoning Maps. There are two former waste disposal facilities located in the City. The first site is adjacent to the south side of McClellan-Palomar Airport. This site was used for disposal of household waste between 1962 and 1975. No hazardous materials have been identified at the site, and it was closed and capped by the County of San Diego in accordance with Title 14 of the California Code of Regulations. The second site is located in the far northeastern corner of the City, and was also used for the burning of municipal waste. The site has not been operational since 1961 and has since been redeveloped (City of Carlsbad 1994). There are no known illegal dumps with hazardous materials within the City. The construction phase of the proposed project would involve the transport of gasoline and other fuels to project sites for the sole purpose of equipment fueling. Transportation of hazardous materials is overseen by the County of San Diego Department of Health Services. c Airport Safety Hazard McClellan-Palomar Airport is located approximately four miles southeast of the Carlsbad Village Area and is a general aviation, publicly owned airport facility. SANDAG acts as the Airport Land Use Commission (ALUC) for the San Diego region under 1970 state legislation and is charged with developing airport Comprehensive Land Use Plans (CLUP). In cooperation with the County of San Diego, SANDAG has prepared a CLUP for the McClellan-Palomar Airport in order to ”identify areas likely to be impacted by noise and fright activity created by aircraft operations at the airport, ’‘ and “preclude incompatible development from intruding into areas of significant risk resulting from aircraft takeoffs and landing patterns, ’’ (1994 CLUP p. 5). The CLUP identifies Arport Influence Areas. These are areas adjacent to airports which are likely to be affected by noise from aircraft operations at the airport. Within the larger Airport Influence Area, other operational areas, such as the Flight Activity Zone (FAZ), are also identified which reflect specific aircraft operational overflight patterns as outlined in Federal Aviation Administration (FAA) regulations. The Airport Influence Area represents the outer boundary of the ALUC’s planning and review authority and is July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4 6-2 4.6 Hazards and llazardous Materials primarily concerned with development compatibility issues associated with noise impacts and aircraft impacts in the airport vicinity. The FAZ for the McClellan-Palomar Airport was determined based upon noise, flight hazards, and obstruction criteria in accordance with the CalTrans Division of Aeronautics 1983 Airport Land Use Planning Handbook. This handbook includes several examples of airport safety zone shapes based on accident potential. The McClellan-Palomar Airport’s FA2 is identified as containing potential operational flight activity hazards and ”’areas which should be held free from intensive development” (1994 CLUP p.12). In turn the CLUP defines ”intensive development’’ as residential of more than 10 dwelling units per acre, “including high rise development and all uses which involve the assembly of large groups of people (more than 100)” (1994 CLUP p. 12-13). Several project components are located within the McClellan-Palomar Arport’s FAZ as delineated by the CLUP, and several project components are within two miles of the airport. Wildfire Hazards The project components would primarily be located within developed areas and roadways; however, portions of the proposed project are located within and adjacent to open space areas with potentially flammable materials such as brush, grass or trees. 4.6.2 Significance Criteria The project components would have a significant effect related to hazards and hazardous materials if it would: Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials; Create a significant hazard to the public or environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment; Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school; 0 Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or environment; - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.6-3 - PIO~~ISIOMI Trow for Carnph Propu 4.6 Hazards and Hazardous Materials 0 For a project within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area; 0 For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or worlung in the project area; Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan; or Expose people or structures to a significant risk of loss, injury or death involving wildland Fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands. 4.6.3 Impact Analysis Hazardous Materials and Hazardous Material Sites Impacts due to release of hazardous materials during the construction and operation of project components would be less than significant with incorporation of the project design features described in Table 2-5. More detail on types of hazards impacts is given below. During the operational stage of the proposed project, pipe rupture or lift station failure could result in spillage OF raw sewage, and exposure of the public and the environment to health hazards. However, the pipelines would be constructed with polyvinyl chloride (PVC) pipe, which is highly resistant to rupture. In addition, pump stations included as part of the project are designed with safety features, including an emergency generator in case of electrical failure, and sufficient sewage detainment capacity in the event of generator and/or pump mechanism failure. This would allow time for repair and/or emergency conveyance of the sewage. Should emergency leaks or spills occur, the Sewer Prevention and Response Plan for the CSD will be implemented. The storage of chemicals and use of petroleum Fuel will be required for stationary engines present at some of the pump stations during operation of the proposed project. The use, storage, transportation, and disposal of these substances is regulated by the County Department of Hazardous Waste Management, and will be conducted according to all applicable state, federal and local regulations. The adherence to statutory standards and practices of the proposed project components will reduce the risk of an explosion or July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.6-4 4.6 Hazards and Hazardous Materials release of hazardous substances to the environment due to an accident or upset conditions. Also, no use of extremely hazardous materials such as gaseous chlorine or other chemicals is proposed; therefore, impacts would not be significant. Although the City has relatively few known hazardous materials sites, there is the possibility that unknown sites exist. Also, while some water and sewer master plan facilities would be located within a quarter mile of existing schools, no hazardous emissions would occur (more information on emissions is described in Section 4.2, Air Quality). However, additional project-level analysis is required to determine the significance of potential hazard effects for all project components. Since hazardous materials sites are subject to changing conditions; e.g., closure of known sites, discovery of new hazardous materials sites, site leakages, and/or remediation of existing sites, it is not appropriate to make a project-level significance determination at this program level of analysis. Details on the known hazardous materials locations would need to be investigated at the project level of analysis for individual project components to determine the specifics on location, type, and status of hazardous materials sites that may be affected. The analysis would include a discussion of whether any project component would be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. Accordingly, a project design feature to prepare site-specific hazardous materials analyses has been incorporated in Table 2-5 to ensure impacts remain at a less than significant level. Airport Safety Hazard As discussed above under Existing Conditions, several project components would be located within the Palomar-McClellan Airport Influence Area and FAZ. The project does not involve any construction or long-term operational features that would result in an airport safety hazard for people residing or working in the project area. Activities at Palomar-McCIellan Airport would be unaffected by the proposed project. Impacts would be less than significant. Emergency Response Plans As noted above, the use, storage, transportation, and disposal of hazardous materials is regulated by the County Department of Hazardous Waste Management, and will be conducted according to all applicable state, federal and local regulations. The adherence to statutory standards and practices of the proposed project components will reduce the risk of an explosion or release of hazardous substances to the environment due to an accident or upset conditions. In order to reduce the potential for construction trafFic conflicts July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.6-5 I -. 4.6 Hazards and Hazardous Materials which may include emergency evacuation plans, a traffic control plan would need to be developed as part of the project,, as described in Table 2-5 (also see Section 4.10, Transportation/Circulntion). With the prescribed traffic control plan and adherence to applicable regulations, the project would not significantly impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Wildfire Hazards Due to the undeveloped nature of land and potentially flammable materials such as brush, grass or trees surrounding several project components, construction would pose a slight risk of wildland fires. There is a project design feature listed in Table 2-5 to prepare a brush management plan and to disseminate fire safety information to construction crews would help to ensure impacts would not be significant. As such, the project would not expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands. 4.6.4 Mitigation Measures No significant impacts have been identified; mitigation measures are not necessary. 4.6.5 Residual Impacts after Mitigation Impacts would be less than significant. July 2003 31 94-04 4 6-6 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.7 Hydrology and Water Quality 4.7 HYDROLOGY AND WATER QUALIN The purpose of this section is to assess general surface water hydrology and water quality conditions and identi€y potential hydrology and water quality impacts in the project areas. The information used in this analysis is general in nature and is derived from the most readily available information found in applicable resource and planning documents. Site-specific hydrology reports or drainage studies were not performed for the project areas. The general surface water hydrology and water quality conditions of the project area were based on review of the Water Quality Control Plan for the San Diego Basin (State of California 1994), City of Carlsbad General Plan (1994) and General Plan Master EIR (1994), and the City and County of San Diego online geographical database (www.SanGIS.ord for floodplains. Aerial photography provided by Aerial Access 2002 , and vegetation cover created for the Multiple Habitat Conservation Program (SANDAG 1995) were also reviewed to determine existing land cover and vegetative cover, respectively. A complete listing of these references is included in Chapter 9.0. 4.7.1 Existing Conditions Hydro logy The project components are located within the San Diego Hydrologic Region, which drains west into the Pacific Ocean. The San Diego Hydrologic Region encompasses approximately 3,900 square miles and is further subdivided into 11 major watersheds. The Carlsbad Watershed occupies approximately 210 square miles, extending from Lake Wohlford on the east to the Pacific Ocean on the west and from Vista on the north to Cardiff-by-the- Sea on the south. This watershed includes the cities of Oceanside, Carlsbad, Encinitas, Vista, and Escondido. The watershed is drained by Buena Vista, Agua Hedionda, San Agua Hedionda, Batiquitos, and San Elijo lagoons (Figure 4.7-4). The Carlsbad Watershed is comprised of the following six drainage basins: Loma Alta, Buena Vista Creek, Agua Hedionda, Encinas, San Marcos, and Escondido Creek. The project components occur within the Buena Vista Creek, Agua Hedionda and Encinas drainage basins. A few of the Marcos Creek and some of the major project components are located near the Buena Vista, Agua Hedionda, and Batiquitos lagoons. - The project components occur primarily in the Carlsbad Watershed. -_ - Marcos, and Escondido creeks and contains four coastal lagoons, including Buena Vista, - - project components are located near Buena Vista Creek, Agua Hedionda Creek, and San - - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.7-1 - 4.7 Hydrology and Water Quality One of the project components (component 32) is located within the San Luis Rey Watershed, located immediately north OF the Carlsbad Watershed (Figure 4.7-1). This watershed is drained by the San Luis Rey kver. Component 32 is located within the Lower San Luis drainage basin. Floodplains The Federal Emergency Management Agency (FEMA) has mapped special Flood hazard areas which include land subject to the 100-year flood. A 100-year Flood is deFined as an area OF land that would be inundated by a flood having a 1 percent chance OF occurring in any given year (http://www.Fema.p;ov, - accessed April 2003). The 100-year flood is the standard used by most Federal and state agencies and by the National Flood Insurance Program (NFIP) For floodplain management and For flood insurance purposes. Several project components would cross areas located within the 100-year floodplains OF Buena Vista Creek and Agua Hedionda Creek (Figure 4.7-1). Water Quality The goal OF the Regional Water Quality Control Board (RWQCB) is to preserve and enhance the quality OF water resources in the San Diego Region For the beneFit OF present and future generations (RWQCB 1994). In accordance with the federal Clean Water Act, the RWQCB adopted a Water Quality Covltrol Plan (1994) which recognized the regional differences in existing water quality, the beneficial uses OF the region’s ground and surface waters, and local water quality conditions and problems. As identified in the Water Quality Control Vista Creek, Agua Hedionda Creek, San include the following: Plan, the designated beneficial uses For Buena Marcos Creek, and San Luis Rey kver may 0 Municipal and domestic supply Agricultural supply Industrial service supply 0 Contact water recreation 0 Non-contact recreation 0 Warm freshwater habitat 0 WildliFe habitat 0 Rare, threatened and endangered species July 2003 31 94-04 )&ASSOCIATES, mC.1 Carlsbad Water and Sewer Master Plan Updates Program EIR Prafeirlonol Teams /or Complrr Pmj& 4.7-2 c c c 4.7 Hydrology and Water Quality Beneficial uses for Buena Vista, Agua Hedionda, and Batiquitos Lagoons may include the following: 0 0 0 0 0 0 0 0 0 0 0 0 Navigation Contact water recreation Non-contact recreation Commercial and sport fishing Estuarine habitat Wildlife habitat Rare, threatened and endangered species Marine habitat Aquaculture Migration of aquatic organisms Shellfish harvesting Warm freshwater habitat Regulatory Considerations The principle federal law regulating surface water quality is the 1972 Clean Water Act. The Clean Water Act sets up a system of water quality standards, discharge limitations, and permits. Under Section 404 of the Clean Water Act, the USACOE regulates discharges of dredged or fill material into waters of the U.S. Activities that may result in the dredge or fill of waters of the U.S. require issuance of a Section 404 permit from the aACOE. Under Section 401 of the Clean Water Act, a state water quality certification must be obtained whenever an application for a federal permit for discharge of pollutants into waters of the U.S., such as a Section 404 permit, is submitted. The Section 401 certification requires any activity affecting waters of the U.S. be in compliance with all applicable water quality standards, limitations and restrictions. Division 7 of the California Water Code, commonly referred to as the state Porter-Cologne Water Quality Act, is the principal state law enacted to establish requirements for adequate planning, implementation, management, and enforcement for the control of water quality. This act established a regulatory program to protect water quality and beneficial uses of all state waters. The act also established the State Water Resources Control Board (SWRCB) and RWQCB as state agencies responsible for water quality control. For the San Diego Hydrologic Region, water quality is regulated by the RWQCB, Region 9 of the SWRCB. July 2003 31 94-04 4 7-5 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.7 Hydrolow and Water Quality Conformance with the Clean Water Act and Porter-Cologne Water Quality Act is required for any discharges, including erosion, into waters of the U.S. through compliance with the SWRCB’s NPDES General Construction Permit. Issuance of a NPDES Permit requires preparation of a Notice of Intent with the SWRCB and development of a SWPPP and monitoring program that incorporates applicable BMPs. Construction activity would also be subject to the erosion control requirements set forth in the City’s Grading Ordinance. Other applicable regulations include Sections 1601-1603 of the California Fish and Game Code. The CDFG regulates wetland areas as defined by the Fish and Game Code. A Section 1601/1603 Streambed Alteration Agreement is required from CDFG whenever CDFG jurisdictional wetlands are altered or fish or wildlife resources are adversely affected. Additional information related to wetlands is found in Section 4.3, Biological Resources. 4.7.2 Significance Criteria The project components would have a significant effect related to hydrology and water quality if it would: Violate any water quality standards or waster discharge requirements; Substantially deplete groundwater supplies or interfere substantially with ground water recharge such that there would be a net deficit in aquifer volume or a lowering of the local ground water table level (i.e., the production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted); Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site; Result in impacts to groundwater quality; Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site; July 2003 31 94-04 Carlsbad Water and Sewer Master Pian Updates - Program EIR 4 7-6 - Profeniowl Teanu fm Gmpla Rqcm 4.7 Hydrolow and Water Quality 0 0 0 0 0 0 0 0 0 0 0 0 Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the flow rate or amount (volume) of surface runoff in a manner, which would result in flooding on- or off-site; Create or contribute runo€f water, which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; Otherwise substantially degrade water quality; Place housing within a 100-year flood hazard area as'mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map; Place within 100-year flood hazard area structures, which would impede or redirect flood flows; Expose people or structures to a significant risk of loss injury or death involving flooding, including flooding as a result of the failure of a levee or dam; Result in inundation by seiche, tsunami, or mudflow; Result in increased erosion (sediment) into receiving surface waters; Result in increased pollutant discharges (e.g., heavy metals, pathogens, petroleum derivatives, synthetic organics, nutrients, oxygen-demanding substances and trash) into receiving surface waters or other alteration of receiving surface water quality (e.g., temperature, dissolved oxygen or turbidity); Result in changes to receiving water quality (marine, fresh or wetland waters) during or following construction; Result in increases in any pollutant to an already impaired water body as listed on the Clean Water Act Section 303(d) list; or Result in the exceedance of applicable surface or groundwater receiving water quality objectives or degradation of beneficial uses. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates 9 Program EIR 4 7-7 Hydrology and Water Quality 4.7.3 Impact Analysis This section presents the evaluation of potential impacts to hydrology, floodplains, and water quality as a result of implementation of the Water and Sewer Master Plans. A number of project design features that would help minimize the effects of the project on water quality and hydrology are included in Table 2-5. Potential impacts to hydrology, floodplains and water quality were evaluated by overlaying the project components with the San Diego Hydrologic Basin Planning Area Map (RWQCB 1994), aerial photography, MHCP vegetation cover and the SANDAG digital coverage for floodplains. For this program level of analysis, a qualitative assessment of the potential impacts to water resources was conducted. As future project- specific information comes forth for individual project components, subsequent analyses pursuant to CEQA will be conducted that may incorporate a quantitative evaluation of impacts. Water Quality and Drainage For project components that occur in developed areas, such as roadways, no new additional runoff into local drainages is anticipated upon completion of project construction. During construction, runoff and sedimentation into nearby drainages would be minimized and avoided through incorporation of project design features described in Table 2-5, such as the use of gravel bags as erosion control measures. For project components that would cross wetland areas, impacts to water quality could occur as a result of runoff and sediment transport during construction activities. Incorporation of project design features described below would minimize impacts to water quality to less than significant. Construction and operation of a number of project components may require dewatering in pipeline trenches in order to place inhastructures underground. Dewatering of groundwater may result in potential impacts to surface water quality due to the unknown chemical makeup of groundwater. Dewatering and discharge activities are subject to water quality guidelines outlined by the NPDES administered by the San Diego RWQCB. In addition to dewatering, stockpiling of soil removed during construction of trenches may result in sediment-laden runoff from construction sites. The increase in total dissolved solids, minerals and other inorganic materials may enter local drainages and exceed water quality standards. July 2003 31 94-04 -- Carlsbad Water and Sewer Master Plan Updates Program EIR 4.7-a Pmfcrrionol Team fm Complu Propc c 4.7 Hydrolorn and Water Quality Because violation of water quality standards may occur during dewatering, discharge, and trenching associated with construction of project components, impacts to water quality are considered potentially significant. As stated in Section 4.7.1, there are a number of project components located adjacent to the Agua Hedionda Creek and Lagoon, and the Buena Vista Lagoon. These water bodies are identified on the SWRCB’s 2002 Section 303(d) List of Water Quality Limited Segments. Under Section 303(d) of the 1972 Clean Water Act, states, territories and authorized tribes are required to develop a list of water quality limited segments. These waters on the list do not meet water quality standards, even after point sources of pollution have installed the minimum required levels of pollution control technology. The project components under both master plans that have the potential to affect the 303(d) water bodies are identified in Tables S-1 and S-2 and would result in potentially significant impacts to water quality. Hydrology and Groundwater The proposed project involves both minor improvements such as manhole replacements and major improvements sucn as replacement of a sewer main. The construction and operation of the proposed project would not use groundwater and would not directly affect groundwater levels. Dewatering, a method which pumps groundwater into either a surface water body or directly into a stormwater drainage system, may be required to prepare sites for placement of proposed pipelines and other underground facilities; however, the potential impact to groundwater would be temporary and would not substantially deplete groundwater supplies. Also, the amount of groundwater that would be directed to stormwater drainage systems would not exceed capacity for those systems. Impacts to hydrology and groundwater supplies would be less than significant. Floodplains Several project components are located in the 100-year floodplain, as defined by FEMA, and would continue to cross the 100-year floodplain with implementation of improvements to project components. The proposed project involves replacement of manholes, sewer mains and modifications to pump stations and pipelines. No housing is proposed as part of the project, therefore no impacts to housing as a result of flooding would occur with implementation of the proposed project. It is unlikely that the project components occurring within the 100-year floodplain would impede or redirect flow because the majority of the project components would be placed underground. All areas July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.7-9 Prof..rlonnl Team for C0rnPl.X P.a,.ctr 4.7 Hydrology and Water Quality within the floodplain would return to pre-construction contours. The flood capacity would not be altered as a result of the proposed project. Floodplains impacts would be less than significant. Based on this program level of analysis, impacts would potentially occur to all project components located within the 100-year floodplain, as defined by FEU. The potentially significant impacts would be associated with the loss of any project components as result of the scouring action by a flood. Implementation of the mitigation measure described in Section 4.7.4 would reduce potential impacts to below a level of significance. Dredge and fill activities that occur within a floodplain would require the appropriate permits from the ACOE, CDFG and RWQCB. Additional mitigation measures may be required as part of those permits and these site-specific measures would be developed once project level information is assembled for a project component. Other Impacts The project would not result in an increased potential for inundation by seiche, tsunami, or mudflow. Implementation of the master plans would not affect the potential for these events to occur; impacts would be less than significant. 4.7.4 Mitigation Measures Implementation of the following mitigation measure will reduce the likelihood of a loss of a structure within a floodplain during a flood event. For projects proposed with the 100-year floodplain, a scour analysis of the floodplains associated with Buena Vista and Agua Hedionda creeks shall be completed during final project design to determine the likelihood for washout of a pipeline or project facility during a flood event. Design and construction specification of the pipeline will incorporate recommendations from the report to ensure that potential impacts from scouring do not comprise the integrity of the pipeline. The list of projects located within the 100-year floodplain is found in Tables S-1 and S-2. In addition to incorporation of project design features shown in Table 2-5, mitigation measures described below shall be implemented in order to reduce impacts to water quality to less than significant. 31 94-04 4.7-1 0 July 2003 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.7 Hydrology and Water Quality Dewatering activities will be conducted in accordance with standard regulations of the RWQCB. A dewatering permit will be obtained. 0 Discharge of groundwater will require a NPDES General Storm Water Permit that will include provisions for implementation of BMPs to reduce potential water quality impacts. 0 Material stockpiled during construction shall be placed such that interference with onsite drainage patterns will be minimized or avoided. During rain events, stockpiles shall be covered with impermeable materials such as tarps in order to allow flow from the construction site to occur without excessive sediment loading. Potential water quality impacts to 303(d) listed water bodies (Agua Hedionda Creek and Lagoon, Buena Vista Lagoon) will be assessed as part of project-level water quality analyses for each individual project component with a potential to affect these water bodies. The list of project components that would potentially affect the 303(d) water bodies is found in Tables S-1 and S-2. c 4.7.5 Residual Impacts After Mitigation All impacts are mitigable to a level below significance by implementation of the measures listed in Table 2-5 and in Section 4.7.4; the residual impact is less than significant.

The land use analysis of existing land uses was based on a review of land use maps, aerial photographs, and limited site visits. Planned land use information was obtained from applicable planning documents of the affected jurisdictions. A review of the City of Carlsbad’s files pertaining to planned or recently proposed projects within the project study area was also conducted, and City planning staff were consulted. c I c Aside from impacts to the existing and planned land uses analyzed by this section, a number of additional land use related topics are addressed elsewhere in this Program EIR. Aesthetics is discussed in Section4.1; Au Quality issues are described in Section 4.2; Noise is discussed in Section 4.9, and Traffic issues are discussed in Section 4.10. - c 4.8.1 Existing Conditions c c c - Land use planning and development approval is guided by federal, state, and local governmental agencies and their adopted policies and ordinances. Each jurisdiction is responsible for maintaining a quality environment for its citizens and users through adoption of long-range planning documents. These documents contain goals, policies, implementation procedures, and regulatory controls to guide and enforce conformance. The most common guide used by local jurisdictions to define land use patterns is the general plan. Land use elements of general plan documents typically contain those policies and maps governing land use compatibility within the jurisdiction. All zoning within a jurisdiction must be consistent with the plans, programs, and policies of the general plan. The proposed project includes multiple components that are geographically dispersed, predominantly located within the City of Carlsbad. For illustrative purposes, Figure 2-2 shows the general location of project components in relation to the affected jurisdictional entities. The applicable jurisdictions and their adopted planning documents are discussed below, with an emphasis on the policies contained in the respective community facility and land use elements. - Existing Land Use The City of Carlsbad is a coastal jurisdiction bordered generally on the north by the cities of Oceanside and Vista, on the east by Vista and San Marcos, and on the south by Encinitas. Approximately 68 percent of the City is undeveloped, with the remainder being developed with a variety of land uses. Of the developed areas, 55 percent is July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates * Program EIR 4.8-1 4.8 Land Use and Planning residential uses, 17 percent is commercial and/or industrial use, and another 17 percent is comprised of open space uses. The remaining 10 percent of the developed areas consists of public uses and utility right-of-ways. The majority of existing commercial development within the City is located along El Camino Real, immediately south of Highway 78, and south of Cannon Road along 1-5. In addition, existing commercial uses predominate the City's downtown along with numerous hotels and service stations along the 1-5. Industrial land uses are primarily concentrated within the City's centralized industrial corridor which surrounds Palomar Airport and extends in a broad band generally to the eastern and western City limits. The majority of developed areas located immediately north of Palomar Arport in the Carlsbad Research Center and at the 1-5 and Poinsettia Lane interchange consist of mixed industrial/commercial uses. The majority of open space land is composed of three major lagoons located within the City, including Buena Vista, Agua Hedionda and Batiquitos and their associated tributaries. Other major open space areas include Calavera Lake and the Veteran's Memorial Park site. Dispersed Civic activities such as schools, parks, city buildings and storage yards are located throughout the City. Regulations and Planning Policies The Growth Management and Public Facilities Section of the City's General Plan Land Use Element contains goals and objectives, which outline the City's desire to ensure the timely provision of public facilities, and maintenance of its existing facilities, which will adequately serve the projected population and preserve the quality of life of residents. For example, policies within this Element of the General Plan require the City to ensure pipeline capacity will meet demand, as determined by the CMWD and CSD, concurrently with development, and cooperate with other jurisdictions to ensure the timely provision of water distribution and sewage disposal capacity. The Public Utility and Storm Drainage Facilities Section of the City's Circulation Element also contains relevant policies for the provision and maintenance of water and sewer infrastructure. These policies include maintaining master plans for the expansion of local water and sewer facilities, coordinating the planning and construction of public utilities with existing public utilities in adjoining neighborhoods, and ensuring continued coordination between the City and special utility districts and public utility companies operating in Carlsbad. Son Diego County Multiple Habitat Conservation Program As described in Section 4.3, the MHCP is a regional effort conducted in conjunction with Section 10a of the Federal Endangered Species Act and the California Natural Communities Conservation Planning Act and is the framework for development of a - July 2003 31 94-04 Assoc~~s~ mC.1 Carlsbad Water and Sewer Master Plan Updates Program EIR Pwf<m'7"d TenM for cmnplpr P,O,SCU I 4.0-2 - c c c c c 4.8 Land Use and Planning regional habitat preserve for many increasingly rare plant and wildlife species in northwestern San Diego County. The MHCP is a multi-jurisdictional planning effort which has included the cities of Oceanside, Vista, San Marcos, Escondido, Encinitas, Carlsbad, and Solana Beach. Each city is tasked with developing a sub-area plan in order to set about policies and regulatory mechanisms to carry out the goals outlined in the regional MHCP. Other Applicable Regional Plans The project’s consistency with other applicable regional plans are analyzed in the respective section of this Program EIR. These include the SANDAG Congestion Management Plan and Regional Transportation Plan, which are addressed in Section 4. IO; the Regional Ar Quality Strategy (refer to Section 4.2); and the RWQCB Basin Plan for the San Diego Basin (as identified in Section 4.7). 4.8.2 Significance Criteria The proposed project would have a significant effect on land use if it would: Physically divide an established community; Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect; or Conflict with any applicable habitat conservation plan or natural community conservation plan. 4.8.3 Impact Analysis The Master Plans include both major and minor project components, including facilities for water storage, water distribution and sewer collection that interact with local land uses in a number of ways. Most of the projects included in the Master Plans fall into two major categories. The first category includes below-ground facilities such as pipelines which are installed in easements or rights-of-way and do not have local land use effects of significance after installation or rehabilitation, except when maintenance is required. The second category includes more visible improvements such as water storage reservoirs, pump stations, and lift stations, which can be built partially or completely aboveground. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.8-3 Prafcu~onol Temu /or Cmplu Prqccrr 4.8 Land Use and Planning Pipelines, and to a lesser extent other water and sewer infrastructure, are installed in public rights-of-way in existing or planned roads as much as possible. During construction and if maintenance is necessary, there are potential indirect impacts associated with traffic and possible conflicts with other utilities. Impacts may also occur in areas where pipelines are installed in public street rights-of-way or to natural resources where pipelines leave public street rights-of-way to connect, for instance, to reservoirs or pump stations. As shown in Figure 2-2, a majority of proposed facility improvements will be rehabilitated or constructed either on public property already developed with similar facilities, or, in the case of pipelines, within existing public roadways and utility rights-of-way. In some cases, pipelines may be routed in private or easement roads that provide access to private property and residences. Construction for either installation of new facilities or rehabilitation of existing components can affect access and the grade or surfacing of the road. Therefore, as part of the project design features, the Districts will be required to conduct the work in such a way that reasonable access is maintained throughout and to restore road surfaces, in both public and private rights-of-way, to their pre-existing condition or better (refer to Table 2-5). Development and rehabilitation of the master planned facilities may occur in areas where sensitive natural or cultural resources are present. It is the policy of the Districts that wherever such impacts from projects within the scope of the Program EIR may occur, they will be mitigated to a level below significance. General mitigation guidelines are established in this Program EIR and are to be followed on a project-specific basis as discussed in the Biological Resources, Cultural Resources, and Geology and Soils sections of the document. These mitigation measures are designed to reduce the potential impacts to below a level of significance. The water components located near the Maerkle Reservoir (components 28 and 29) are proposed to be constructed on undeveloped land, designated Open Space in the Carlsbad General Plan. The Open Space designation does not preclude these necessary utility/infrastructure facilities. Also, these facilities would be similar to the existing Maerkle PS and reservoir, and would be consistent with the existing land use and would not conflict with the Open Space designation. Component 28, the proposed reservoir, would not be visually intrusive since it is proposed to be buried adjacent to the existing reservoir. Enlarging the existing Maerkle PS (water component 29) would not alter the existing land use of the site. Land use impacts would be less than significant.

Although the existing easterly section of the road is not built, the watermain would be co-located within the future road, and land use impacts would be less than significant. Also, a number of large water lines are proposed within future roads that are being developed as part of other development projects in the City (as shown in Figure 2-3 and described in Section 2.4). These include components 6, 9, 10, 12, 13, 14, 15, and 23. Since these facilities would be installed within future roads as part of those projects, they would be compatible from a land use perspective and impacts would not be significant. Further analysis is provided as part of the individual CEaA reviews as identified in Table 2-2. The proposed site for water component 20, the proposed pump station at the southeast corner of Palomar Anport Road and El Camino Real, is designated Governmental Facility in the City General Plan. The project would be consistent with this designation and impacts would be less than significant. The new water reservoir proposed adjacent to the existing D-3 reservoir (component 27) would be located in a residential area, and due to its proposed siting adjacent to similar infrastructure uses, land use impacts would be less than significant. The proposed sewer lift station abandonments and improvement projects would not result in any long-term land use conflicts. Lift station improvement projects would not result in an alteration of the existing or planned land use. Similarly, removal of a lift station would result in land being cleared of the aboveground facility and would not result in land use effects. For water component 32, located within the city of Oceanside, the abandonment of nine water wells near Foussat Road is currently being reviewed in a separate CEaA document (City of Carlsbad 2003). Within the City of San Marcos just east of Carlsbad, water component 26 is located within the Palomar Anport Road right-of-way and due to its proposed location, is unlikely to conflict with any land use plans of the City of San Marcos. Potential conflicts with utilities, including natural gas lines or electrical conduits, are identified in the engineering and design stage of all projects. The Districts, policy is to coordinate all construction, repair, and maintenance activities with any other utility owner whose facilities may be affected in the planning stage. Potential impacts are mitigated to the greatest extent feasible and to a level below significance by this policy.

Complex Koirru Land Use and Planning land Use Compatibility The City retains authority for existing infrastructure and planned capacity improvements to support all designated land uses in the City of Carlsbad General Plan. The CMWD and CSD facilities are necessary infrastructure elements for all types of development. The Water and Sewer Master Plan Updates were developed after a careful survey of existing development, planned development, General Plan designations, and other land use planning features and documents. As a result, the projected phasing and intensity of future improvements are based on the most up-to-date land use information available. The Master Plans were designed to provide the City with orderly plans for the development of water utilities to meet the present and future needs of the City as reflected in the General Plan. The plans are therefore consistent with and provide a blueprint for implementing the policies related to water and sewer infrastructure expressed in the General Plan Land Use and Circulation Elements. As described in Section 4.8.1, these policies mandate the orderly development of adequate water utility facilities to meet existing needs and future growth requirements. The Master Plan Updates are intended by the CMWD and CSD to implement the policies of the General Plan Land Use Element in an integrated fashion, and have been designed to be consistent with the General Plan. From a standpoint of local land use designations and zoning, all project components in the Master Plan Updates are either compatible with local land use regulations or would be compatible, subject to use permit limitations. The projects would not physically divide an established community; once construction is complete, the linear pipeline projects would not be noticeable. Land use impacts would be less than significant. Additionally, as discussed in the TransportatiordTraffic section, potential impacts for traffic will also be mitigated to the greatest extent feasible by coordination with the affected planning departments, as well as all other agencies with jurisdiction over the project. Where work is done in public street rights-of-way, project design plans will be required to conform with the most current edition of the Caltrans Traffic Control Manual. Further, all traffic control plans shall be designed in accordance with Caltrans’ Manual of Traffic Controls for Construction and Maintenance Work Zones. Adherence with these project design features will ensure that traffic-related land use impacts do not breach a level of significance (refer to Table 2. I). The coastal zone for the City of Carlsbad is located west of El Camino Real. As portions of the proposed project are located in this area, they have the potential to affect the July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.8-6 Profcsstmd TIOW for Cmnplu Prqrcrr c c c 4.8 Land Use and Planning Coastal Zone, and some activities will be subject to a Coastal Development Permit (CDP). Since Carlsbad has an approved Local Coastal Program (LCP) as of 1996, the City acts as the local permitting authority for the issuance of CDPs for projects located within its Coastal Zone, with a few exceptions. There are “exclusionary areas” where the state retains permitting authority. For example, Agua Hedionda Lagoon lies outside of Carlsbad’s permitting authority, and projects in its vicinity would require a CDP from the State California Coastal Commission. All projects in the Carlsbad coastal zone will require review for consistency with the LCP and California Coastal Act prior to issuance of a CDP. The future required review and issuance of CDPs would ensure that infrastructure projects, particularly those located outside of public rights-of-way or property or in sensitive areas, will be consistent with the LCP; individual components would require this review on a project-by-project basis to ensure that impacts would be less than significant. For other development approvals by local jurisdictions outside the City of Carlsbad but within the Districts’ service areas, project design engineers are required to coordinate the design with the City. These projects might also require discretionary permits. Future potential land use impacts that might result from a need for necessary infrastructure improvements would be evaluated at the time of project design and review. The projects proposed in the Master Plan Updates would not conflict with any existing general plan, coastal plan or any other land use plan or policy. Consequently, no adverse impact to land use planning would result from implementation of the Master Plans. 4.8.4 Mitigation Measures No mitigation measures are required beyond those identified in the Biological Resources, Cultural Resources, and Geology and Soils sections of this document. 4.8.5 Residual Impact After Mitigation Land use impacts would be less than significant.

CmnPIU Pro,.cu c 4.9 Noise 4.9 NOISE c This section will provide existing noise guidelines information and analyze the proposed project’s consistency with these guidelines. Noise is defined as unwanted or undesired sound. Sound levels can be measured fairly easily, however, the variability is subjective and physical response to sound complicates the identification of noise impacts. The basic terminology and concepts of noise are described below. Noise is generally defined as unwanted sound. The noise environment in the City of Carlsbad is characterized by various levels of natural, man-made, and mechanical noise generated from airborne, mobile, and stationary sources. Sound (noise) levels are measured in decibels (dB). Table 4.9-1 depicts common sound levels for various noise sources. Community noise levels are measured in terms of the A-weighted sound level. The A-weighted scale adjusts the measured sound levels to generally correspond with the way the human ear responds to sound. All sound levels discussed in this section are A-weighted. TABLE 4.9-1 TYPICAL SOUND LEVELS MEASURED IN THE ENVIRONMENT AND INDUSTRY Civil Defense Siren (100 ft.) Normal Conversati Table contents compiled through various sources. See references Section 9.0. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Pronram EIR 4.9-1 4.9 Noise Additional units of measurement have been developed to evaluate the long-term characteristics of sound. The equivalent sound level or Leq, also referred to as the average sound level, is a single-number representing the fluctuating sound level in dB over a specified period of time. It is a sound-energy average of the fluctuating level and is equal to a constant unchanging sound of that dB level. People are generally more sensitive and annoyed by noise during the evening and nighttime. Therefore, another noise descriptor used in community noise assessments, termed the Community Noise Equivalent Level (CNEL) was introduced. The CNEL scale represents a time-weighted 24-hour sensitivity during the evening (7:OO p.m. to 1O:OO p.m.) and nighttime hours (10 p.m. to 7 a.m.) by adding five and ten decibels, respectively, to the average sound levels occurring during these hours. 4.9.1 Existing Conditions According to the General Plan (1994), the primary noise-sensitive land use in the City of Carlsbad is residential land use. Libraries, churches and some passive parks and recreation areas also represent noise sensitive land uses. Traffic represents the most significant noise source in Carlsbad. Interstate 5 has the greatest existing and projected roadway noise emissions. In addition, 1-5 impacts the greatest number of existing dwellings. Additional noise sources located within the city include: Palomar Auport, located west of El Camino Real, just north of Palomar Airport Road; the AT&SF Railroad, which runs parallel to the coastline through its 6.5 mile length in Carlsbad; and motor boats which utilize the Agua Hedionda Lagoon. Noise generation is minimal or limited in the exclusively residential portions of the City, and in rural or undeveloped areas. City of Carlsbad General Plan The primary goal of the Noise Element of the Carlsbad General Plan is to achieve and maintain an environment which is free from objectionable, excessive or harmful noise (City of Carlsbad 1994). It establishes goals, objectives, and policies to help mitigate existing and future environmental noise levels from sources within and adjacent to the City, and provides policies and action programs to implement the goals and objectives. Noise Control Ordinance The City of Carlsbad does not have a comprehensive noise ordinance. However, Chapter 8.48 limits hours of construction to normal weekday working hours. Specifically, construction noise is not allowed after sunset any day; before 7:OO a.m. uFeekdays; before - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4.9-2 - ProfrrrnonaI Porn io, Campla Pm~rcu Noise 8:OO a.m. Saturday, Sunday, and on seven holidays. The City enforces the California Penal Code Section 415 when annoying noise occurs. Also, the City has a Noise Guidelines Manual (September 1995) with which projects must be consistent. 4.9.2 Significance Criteria The following criteria are used to determine the significance of an impact: Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance or applicable standards of other agencies; Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels; A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project; A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project; For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels; or For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels. 4.9.3 Impact Analysis Potential noise impacts are commonly divided into two groups; temporary and long-term. Temporary impacts are usually associated with noise generated by construction activities. Long-term impacts are associated with impacts on surrounding land uses generated from operation and maintenance of the project related facilities. The construction noise specifics of the various phases of the project warrant additional analysis by technical noise studies prepared in accordance with the applicable CEQA guidelines. July 2003 31 94-04 4.9-3 Carlsbad Water and Sewer Master Plan Updates * Program EIR fioferwmd TIOM fm Cornpler Projrtu Noise Short-term acoustic impacts are those associated with construction activities necessary to implement the proposed facilities. Associated noise levels will be higher than the existing ambient noise levels, but would subside once construction is completed. Two types of noise impacts should be considered during the construction phase. First, the transport of workers and equipment to the construction areas will incrementally increase noise levels along the roadways leading to and from the project areas. Second, the noise generated by the actual on-site construction activities will be audible to adjacent sensitive receptors. The highest noise levels associated with construction typically occur with earth moving equipment which includes excavating machinery (backhoes, bulldozers, excavators, trenchers, front loaders, etc.) and road building equipment (compactors, scrapers, graders, etc.). Noise levels at 50 feet from earth moving equipment typically range from 73 to 96 dBA (Bolt, Beranek, and Newman 1971). Construction equipment noise typically has a drop-off rate of 6 dBA per doubling of distance (Le., at 100 feet, noise levels associated with the earth moving equipment would be approximately 67 to 90 dBA). Construction and rehabilitation efforts for the project components would result in noise impacts to various types of sensitive receptors including, residences, businesses, schools, and libraries. The associated construction activities would increase the ambient noise levels above existing conditions, which could be perceived as annoying to sensitive receptors in the area. However, this impact is temporary and would disappear once construction is completed. Provided that all construction activities do not conflict with the Carlsbad Noise Control Ordinance, no significant impacts would result from construction. Construction activities are not anticipated to exceed the noise standards of affected jurisdictions. To help minimize the impacts of construction the City shall provide public noticing for their proposed construction activities, and will appoint a public liaison who will respond to concerns of neighboring residents about noise and other construction disturbance (refer to Table 2-5). The projects within the two Master Plan Updates were evaluated for the potential to generate significant noise that would affect nearby sensitive receptors. Some of the projects (e.g., the new PS proposed with water component 20), while potentially resulting in increases in ambient noise levels, are not located in areas adjacent to sensitive receptors. One project, sewer component 12, involves reducing noise and incorporating odor control measures. Of the projects in the two Master Plan Updates, the following have the potential for significant noise impacts on nearby receptors: July 2003 31 94-04 Carlsbad Water and Sewer Master Pian Updates Program EIR 4.9-4 Pmfcriionnl Tmmr for Complu Projects Noise c c New water reservoir next to existing D-3 Reservoir (water component 27) 0 New water reservoir adjacent to the existing Maerkle Reservoir (water component 28) Maerkle Pump Station Capacity Improvements (water component 29) 0 Calavera PS Upgrades (water component 36) Lift station upgrades at the Terramar, Villas, and Gateshead Lift Stations (sewer component 7) 0 Home Plant Lift Station Improvements (sewer component 9) Agua Hedionda Lift Station Improvements (sewer component 32) South Agua Hedionda/Kelly Ranch Lift Station (sewer component 34) New pump or lift stations and expansion or improvement of existing pump or lift stations beyond present plant boundaries should be evaluated in the design stage to assure that sensitive receptors are not significantly affected (that is, above 60 dBA CNEL) and applicable engineering mitigation is required if necessary. Noise impacts from construction activities would be minimal within industrial and manufacturing districts, as these areas do not contain sensitive receptors and their associated ambient noise levels are generally high. Similarly, project related construction noise would have no impact within Open Space areas, as these areas are located in remote locations and devoid of sensitive receptors. However, the associated noise could potentially affect wildlife species which utilize the affected Open Space areas for habitat or migration. Construction-related noise impacts to wildlife are discussed in Section 4.3, Biological Resources. No significant noise related impacts would occur within industrial, manufacturing or open space areas as a result of short-term construction activities. Operation of the project facilities would not create a significant impact on any sensitive receptors with regard to noise. Once constructed, the pipeline segments would not result in any noise impacts as the fluid flow of water or sewage within an underground pipeline would not be audible. Noise levels are not anticipated to exceed the limits expressed in the City’s Noise Guidelines Manual. Occasional maintenance and emergency repair July 2003 31 94-04 4 9-5 Carlsbad Water and Sewer Master Plan Updates Program EIR Prafririonol Team fm Complex Projrcta 4.9 Noise activities will generate some additional noise; however, these activities are sporadic in nature and do not occur at the same location For long periods OF time. Typically, pump stations and lift stations OF the types proposed in the Master Plan Updates do not produce high levels of operational noise. PS Facilities are most likely to produce perceptible noise off the facility site, with the source of noise being the motors used to power the pumps. In normal operation, the pumps are powered by electric motors, and pumping stations are typically housed in masonry enclosures, which are eFfective in attenuating noise. The Districts also attempt to assure that an adequate area around their pumping stations and other Facilities buffers the facilities from nearby sensitive receptors, such as residences to ensure that noise does not exceed the Noise Guidelines limits. In some cases, the City provides additional noise mitigation in those Facilities. Also, pressure-reducing stations do not typically produce any noticeable noise outside of the structure. Therefore, no long-term operational noise impacts are anticipated to occur as a result of the project. The project’s potential to result in excessive groundborne vibration to sensitive receptors would need to be assessed at the individual pro] ect-level review. Groundborne vibration can occur in areas adjacent to pump stations. In addition, some Facilities may require blasting activities during construction, which may also result in vibration effects. Although a number OF the proposed project components would be located within the McClellan-Palomar Arport Land Use Plan, the project would not expose people residing or working in the project area to excessive noise levels. The construction of the facilities in the airport vicinity would be short-term and would not contribute to a long-term noise eFfect. Additional information regarding the Airport Land Use Plan is described in Section 4.6. 4.9.4 Mitigation Measures - , The projects designated For a noise study in Tables S-1 and S-2 shall be evaluated in the design and environmental Initial Study phases to determine if potential noise impacts in excess of City Noise Control Ordinance limits or the City’s Noise Guidelines Manual would result. If such a potential exists, a noise study shall be conducted including recommendations for mitigation. Mitigation shall be designed to assure that noise produced by operation of the Facility shall not cause the limits in the Noise Control Ordinance or Noise Guidelines Manual to be exceeded, and any such mitigation shall be required as part of the project.

The following analysis provides information on the existing area roadways, and identifies current lane configurations, average daily traffic (ADT) volume, roadway capacity, and level of service (LOS). Roadway capacity has been defined as the maximum number of vehicles that can pass over a roadway during a given period of time under prevailing roadway and traffic conditions. The maximum capacity is determined from roadway factors (such as right-of-way widths, lateral clearance, shoulders, surface conditions, alignment and grades) as well as traffic factors (such as vehicle composition, distribution by lane, pealung characteristics and traffic control devices, intersections, etc.). Capacity is usually given as the hourly service volume at the upper limit of LOS, which indicates the maximum number of vehicles that could be expected to travel a section of roadway in a day. 4.1 0.1 Existing Conditions The City of Carlsbad’s transportation system is generally meandering, due to the presence of natural topographic constraints (e.g., steep hills, lagoons). Portions of the I- 5 freeway and SR-78 bring regional traffic into and through the City. Several of the City’s existing major arterials also carry through traffic as well as local traffic. The City of Carlsbad contains three major arterial roads including El Camino Real which runs north and south through the center of the City, Palomar lrport Road which runs east/west through the center of the City, and Rancho Santa Fe Road which runs along the southern and easterly boundary of the City. Most City streets are paved with curbs and gutters, and water and sewer pipelines are usually located in public street rights-of-way for easy access and maintenance. Private roadways and easements are also sometimes used to provide access to the various water and sewer facilities. Where construction occurs in public right-of-way, the City has standardized procedures for regulating traffic during construction projects. The procedures are based on the accepted engineering principles and practiced cited in the Caltrans Traffic Control Manual for traffic safety and control in construction work zones. These procedures include traffic schedules, signage, lighting, lane configurations, and lane markers. July 2003 31 94-04 4.10-1 Carlsbad Water and Sewer Master Plan Updates - Program EIR 4.1 0 Transportation/Traffic 4.1 0.2 Significance Criteria A project is considered to have a significant impact on the operation of a roadway segment or intersection when one OF the Following occurs: Cause an increase in traFFic, which is substantial in relation to the existing traffic load and capacity OF the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections); Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency For designated roads or highways; Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks; Substantially increase hazards due to a design Feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., Farm equipment); Result in inadequate emergency access; Result in insufficient parking capacity; ConFlict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turn-outs, bicycle racks). 4.1 0.3 Impact Analysis Traffic Generation Most OF the proposed Facilities, once installed, would require idrequent site visits by maintenance stafF. The project would predominantly result in short-term traffic effects during construction of the various project components. The short-term eFFects would require additional review once detailed project construction plans become available. Impacts were generally evaluated For portions OF the proposed project that would require construction within existing streets. The operational phase OF the proposed project would generate minimal traffic required For routine maintenance and emergency repair. Some increase in traFFic would result From maintenance activities in the Form OF employee trips -- July 2003 3 1 94-04 4 10-2 - Carlsbad Water and Sewer Master Plan Updates Program EIR Proferrlannl Team 10, Caiplu Pm~rcu c c c c c c c 4.1 0 Transportation/Trafc and the delivery of supplies, but these would be overall minor activities when compared to the existing circulation system. The proposed project would not result in long-term impacts to traffic. Traffic will be generated during project construction. The primary sources of construction traffic would be workers, delivery of materials and removal of excess material. Typically for pipeline projects, approximately 8 to 12 construction workers are expected on a daily basis for each segment of pipe being constructed and/or rehabilitated, and an average of 4 trucks per day to and from the site is anticipated for delivery and removal of materials. Project construction within study area roadways would consist of excavation, pipeline construction, backfilling and repaving. A typical pipeline construction area is approximately 30 feet wide and would progress at a rate of approximately 200 feet per day. Multiple project components may be constructed simultaneously. Construction of all project components, creation of staging and storage areas, and installation of facilities such as PRS components will take place, in part, in existing public street rights-of-way, along with the use of construction equipment. Potential impacts include disruption of traffic from lane closures, detours, increased truck and other construction-related traffic, and disruption of access to local businesses and residences in some cases. These types of impacts may affect local circulation during the short-term course of construction activities. Short-term construction traffic would require implementation of a traffic control plan (TCP). The project TCPs would need to be developed in accordance with City of Carlsbad and Caltrans traffic control guidelines and would need to specifically address construction traffic, traffic safety measures, and use of signage and flag personnel where necessary (refer to Section 4. j0.4). The construction traffic-related specifics of the various phases of the project warrant additional analysis by technical traffic survey/studies prepared in accordance with the applicable CEQA guidelines. Overall, short-term traffic impacts are considered potentially signifcant. This conclusion would be more fully explored by the project-specific technical traffic studies prepared at later design phases for each project, as necessary. Refer to Section 4.10.4 below for a description of traffic mitigation measures. Air Traffic Patterns The project does not involve any changes in air traffic patterns, and does not involve construction of facilities that would have the potential to impact air traffic patterns. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4 10-3 Profmzmal Team fm Complu Prolcctr 4.10 Transportation/Trafc Please refer to Section 4.6, Hazards and Hazardous Materials for additional information on air traffic safety. Impacts would be less than significant. Hazards Construction activities would require lane closures which could result in short-term impacts to traffic patterns and result in temporary traffic congestion and potential traffic hazards. Construction of the various components would also cause temporary disruption of access to residences and businesses along the construction route. Consequently, portions of the affected roadway links may require detours or flagger assistance to maintain acceptable operation of the roadways, and access to all properties. Closing or altering access to individual properties, lane closures, and subjecting any portion of existing roadways to notable increases in construction traffic are considered potentially significant, and mitigation is required. Construction of sewer component 30 (the Buena Vista Lft Station forcemain) would involve encroachment within the right-of-way of 1-5. Altering access or interfering with a public facility such as Caltrans’ interstate freeway system is considered a potentially significant impact; therefore, mitigation is required. Emergency Access The project’s effects on emergency access and emergency response plans is analyzed in Section 4.6.3; the project would not result in inadequate emergency access, and impacts would be less than significant. Parking Effects Construction of the individual projects would result in some short-term parking needs by workers at the sites. No portion of the projects would resuIt in long-term parking needs by maintenance crews or others. Because relatively few vehicles are necessary, and because most parking needs would be short-term during construction only, impacts to existing parlung capacity are not anticipated to be significant. Consistency with Other Plans and Policies Supporting Alternative Transportation SANDAG’s Congestion Management Plan (CMP) was adopted on November 11, 1991, and is intended to directly link land use, transportation and air quality concerns through July 2003 3194-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 4 10-4 c - c 4.10 Transportation/Traffic level of service performance. Local agencies are required by statute to conForm to the CMP. The CMP requires an enhanced CEQA review For all large projects that are expected to generate more than 2,400 ADT or more than 200 weekday peak hour trips. Since the project is calculated to generate less than these amounts, this level OF review is not required of the proposed project and the project is consistent with the goals of the CMP, and impacts would be less than significant. Similarly, SANDAG has produced a 2020 Regional Transportation Plan (RTP) in April 2000 that identiFies those projects needed to improve transportation significantly over the next 20 years. The RTP sets four key objectives; speciFically, average time to get to work (24 minutes or less), number OF miles of deFicient segments in the freeway system (29 miles or less), number of transit riders (minimum 400,000 trips per day), and increase in transportation revenues (65 percent increase). The RTP contains plans and policies to improve mobility in the region by recommending new facilities and the expansion OF transit services, programs to manage travel demand, and changes to local land use policies. The proposed project, although temporarily disrupting traFFic flow on regional roadways during construction, would not conflict with overall goals of the RTP, and impacts would be less than significant. 4.1 0.4 Mitigation Measures Tables S-I and S-2 identify the project components that would require the following mitigation meas ures . 1. The Districts will obtain an encroachment permit from respective local and state authorities, as required prior to the commencement of the construction phase within the affected right-OF-ways. This process will include submittal OF project plans, review OF plans by the respective authorities, possible revisions OF the plans relative to concerns brought Forth by the issuing agency and issuance OF the respective permit. Potential permitting agencies include Caltrans, North County Transit District (NCTD), Cities, and the County OF San Diego. All roadway features (signs, pavement, delineation, roadway surFace) and structures with the State right-OF-way shall be protected, maintained in a temporary condition, or restored. 2. A TCP shall be prepared prior to construction and implemented For all affected roadways. The TCP shall be prepared in accordance with Caltrans Manual OF Traffic Controls for Construction and Maintenance Work Zones [1996 (Revision 2) edition], and with the City of Carlsbad’s trafFic control guidelines. It will be July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates 4 10-5 Program EIR 4.10 Transportatlon/Traffic prepared to ensure that access will be maintained to individual properties and businesses, and that emergency access will not be restricted. Additionally, the TCP will ensure that congestion and delay of traffic resulting from project construction are not substantially increased and will be of a short-term nature. The TCP will show all signage, striping, delineate detours, flagging operations, and any other procedures which will be used during construction to guide motorists safely through the construction zone and allow for a minimum of one lane of travel. The TCP will also include provisions for coordinating with local emergency service providers regarding construction times and locations of lane closures as well as specifications for bicycle lane safety. The limits of construction work area(s) and suggested alternate traffic routes for through traffic will be published in a local newspaper periodically throughout the construction period. In addition, the construction contractor or the Districts shall provide not less than a two-week written notice prior to the start of construction by mailing to owners/occupants along streets to be impacted during construction. During construction, the Districts shall ensure that continuous, unobstructed, safe and adequate pedestrian and vehicular access to and from public facilities such as public utility stations and community centers will be provided, and to commercial/ industrial establishments. If normal access to these facilities is blocked by construction alternative access shall be provided. Should this occur, the Districts shall coordinate with the businesses or each facility’s administrators in preparing a plan for alternative access. During construction, the Districts shall maintain continuous vehicular and pedestrian access to residential driveways from the public street to the private property line, except where necessary construction precludes such continuous access for reasonable periods of time. For example, when a given pipeline segment is initially being excavated, access to individual driveways may be closed during the course of a workday. Access shall be reestablished at the end of the workday. If a driveway needs to be closed or interfered with as described above, the construction contractor shall notify the owner or occupant of the closure of the driveway at least five working days prior to the closure. Methods to maintain safe vehicular and pedestrian access include the installation of temporary bridge or steel plates to cross over unfilled excavations. Whenever sidewalks or roadways are removed for construction, the contractor shall place - July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates * Program EIR 4.10-6 - Pioferr~onnl Teom tor Complu Pmpr.

The TCP shall include provisions to ensure that the construction contractor’s work in any public street does not interfere unnecessarily with the work of other agencies vehicles, such as emergency service providers, mail delivery, school buses, waste services, or transit vehicles. 3. During project design, the Districts shall coordinate with each jurisdiction, as well as its own transit division which may be affected by the project to determine the exact limits OF project construction. All work proposed within the State right-of- way shall be dimensioned in metric units.

Section 15355 of the CEaA Guidelines defines cumulative impacts as “...two or more individual environmental effects which, when considered together, are considerable or which compound or increase other environmental impacts.” Cumulative impacts may result from individual effects of a single project or the effects of several projects that are developed within a particular window of time. The discussion of cumulative impacts is guided by the standards of practicality and reasonableness. Two methods may be used to evaluate cumulative impacts: a) a list of past, present and probable future projects (Cal. Code Regs., Title 14 §15130(b)(l)(A); or b) a summary of projections from a planning document which describes or evaluates regional conditions ((Cal. Code Regs., Title 14 §15130(b)(2)(B)). For this analysis, the projection method is used. Projections are based on SANDAG year 2020 population projections and the City of Carlsbad General Plan Land Use Element density projections. The implementation of the CIP projects of the Water and Sewer Master Plans would primarily involve expansion and rehabilitation of existing facilities as well as construction of new facilities. This Program EIR evaluates the potential effects of these projects and recommends mitigation measures to be implemented after subsequent, project-level environmental review, where necessary, at the time of approval of each project. The Master Plan Updates propose a program of phased improvements keyed to the City’s growth and include recommended upgrades and new facilities to meet the projected needs of the City. Cumulative effects of the Program EIR can be considered in relation to the environmental effects of all development throughout the City. In the discussion in Section 5.2 below, cumulative effects are considered for the issues discussed in Chapter 4 of this PEIR. 5.2 ANALYSIS OF CUMULATIVE IMPACTS Aesthetics The City of Carlsbad is a predominantly residential community with a coastal and mixed development atmosphere. This visual landscape consists of a mixture of urban uses, infrastructure, and hillsides. As Carlsbad continues to develop, the appearance of the City July 2003 3194-04 Carlsbad Water and Sewer Master Plan Updates - Program EIR 5-1 Pmfrmonnl Team /or Complex Prqecu Cumulative Impacts will continue to change to a more urbanized landscape. Cumulative impacts related to aesthetics for the CIP projects are not considered significant, since they are expected features in the developed landscape, are mostly underground, are modifications to existing facilities, and would receive design review for conformance with community aesthetic standards in future environmental documentation and/or project design review. Ai r Q u a I i ty Except in cases of point-source pollution and rare traffic-related air pollution “hot spots”, air quality must be considered on a cumulative, air basin-wide basis. Strategies for the control of both point-source and mobile pollution generation are the responsibility of the APCD. APCD rules and regulations apply uniformly throughout the District and the rest of the air basin and to all potential sources of pollutant emissions. Thus, air pollution control is applied on a cumulative basis. As noted in Section 4.2, Air Quality, the proposed Master Plans are consistent with the growth assumptions of the regional air quality plan and incorporate all feasible and available air quality control measures through regulation by APCD. Also, the RAQS is based on development as planned under the applicable general plans. The Master Plans are consistent with the planned development as identified in the City of Carlsbad General Plan; therefore, the project is consistent with the RAQS. Cumulative effects would be less than significant. Biological Resources The project components in the Master Plans are intended to serve growth in the City of Carlsbad, and are required as infrastructure in support of existing and planned future growth in the City. Water and sewer facilities have an initial impact on biological resources where they are located in undeveloped areas, but are usually low-activity facilities after construction. They may, therefore, be compatible with surrounding biological conservation in many situations. The Master Plan facilities are, however, intended to serve development in the City and should be considered together with the effects of development on biological resources in the assessment of cumulative effects. - The City’s environmental review process for all development projects, including water and sewer facilities, requires an assessment of impacts and appropriate mitigation where there is a potential for an effect on biological resources. The process includes the surveys and biological resources technical reports if necessary. Mitigation is accomplished in standardized ways, and for some impacts, such as effects on endangered species and wetlands, follows the procedures required by resource agencies such as the USFWS and - identification of such potential effects in an environmental Initial Study and subsequent .- July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 5-2 5.0 Cumulative Impacts CDFG. Effects on resources such as wetlands and state and federally listed species also require permits from the resource agencies. As described in Section 4.3, the City is participating in the MHCP, which is intended to mitigate for the biological impacts of planned growth through the creation of a new process for the issuance of federal and state permits and other authorizations under federal and state law. The City of Carlsbad is developing its own Subarea Plan (the Habitat Management Plan) within the MHCP framework. The end result of the MHCP planning process is to provide a regional conservation plan to mitigate the cumulative effects of growth in the region. Cumulative impacts of Water and Sewer Master Plan projects occurring in the MHCP focused planning areas would be cumulatively significant considered together with other development projects in the City and region, due to temporary losses in habitat value. Mitigation would be accomplished through the assessment and mitigation of project- specific impacts as individual components of the Master Plans are implemented and, when the MHCP is implemented, through a regional conservation plan in cooperation with CDFG, USFWS, and other cities in the area. The City of Carlsbad HMP will address cumulative biological effects as part of the MHCP process; however, until that document is implemented, cumulative impacts would be significant and would remain unmitigated. Cultural Resources Many areas within the City are known to be rich in cultural resources. The City requires an evaluation of cultural resources as a part of environmental review for land development projects needing discretionary approval from the City. As part of that review, all cultural resources sites would be evaluated for importance and, if found to be significant, either preserved or mitigated by the recovery of all relevant scientific information represented by the site. The same procedures are followed by other agencies whose projects may affect cultural resources in the City, such as Caltrans and SDGE. Section 4.4, Cultural Resources, established similar mitigation requirements for all Master Plan components that may impact cultural resources. Because this uniform policy is designed in each case to reduce impacts on cultural resources to below a level of significance on site-specific basis, cumulative impacts would be less than significant. Geology and Soils Geologic/soils hazards associated with cumulative development within the City would be evaluated on a site-specific basis. Geologic and soils impacts and required mitigation 31 94-04 5-3 July 2003 Carlsbad Water and Sewer Master Plan Updates Program EIR P~ofm~mual r..mr for comnpler Pro,.<.tr would be evaluated on the respective properties and projects on a project-by-project basis through the use of geotechnical reports and Phase I Site Assessments. Therefore, with implementation of recommended mitigation measures on a project-by-project basis, no significant cumulative geologic/soils impacts are anticipated. Hazards and Hazardous Materials Cumulative hazards and hazardous materials impacts and any potential mitigation would be evaluated on a project-by-project basis as minimal information is available at this program level of analysis. With implementation of recommended mitigation measures in Section 4.6, Hazards and Hazardous Nlaterials, and project-specific mitigation measures identified on a case-by-case basis, no significant cumulative hazards and hazardous materials impacts are anticipated. Hydrology and Water Quality Runoff from project construction areas would contribute an incremental increase in flows within the Buena Vista and Agua Hedionda Creek basins and would combine with increases attributable to adjacent developments. Total runoff in the creek basins would be short-term and would be cumulatively considerable. Project-by-project BMPs, including completing scour analyses for projects within 100-year floodplains and obtaining dewatering permits from RWQCB, would reduce sediment loads and downstream erosion to less than significant. In addition, compliance of all future projects with applicable federal, state and local regulations for stormwater and construction discharges would reduce cumulative impacts to water quality to a level below significance. The Master Plan Update projects would not substantially increase the amount of impervious surfaces and would not result in cumulative hydrologic impacts as a result of increasing cumulative runoff volumes. 31 94-04 5-4 July 2003 Carlsbad Water and Sewer Master Plan Updates Program EIR - Pmfcsswnsl Born 1.7 Complex Rqtc~ 5.0 Cumulative Impacts land Use and Planning Facilities and improvements proposed in the Master Plan Updates are based on growth and population projections derived from SANDAG population estimates and projections. In the course of preparing the Master Plan Updates, existing, proposed and designated land uses were used to generate the capacity data for the modeling of the systems that revealed deficiencies and indicated the need for improvements or new facilities. The location, capacity, and phasing of projects in the Master Plan Updates conform to existing and planned uses overall. The Master Plan Updates projects do not affect land use in the affected jurisdiction, but are designed to match the necessary infrastructure for wastewater in support of the land uses. Adoption of the Master Plan Updates, when considered together with the general plans and other planning for the affected jurisdictions, would not result in significant land use impacts, but would support the jurisdictions’ existing land uses, and development in conformance with applicable general plans. No significant cumulative land use impacts would occur with the proposed Master Plan Updates. Noise As development increases in the City, some increase in ambient noise levels is inevitable, with localized effects. This increase would be due primarily to traffic noise, as roads are constructed to serve new development, and to point sources of noise, such as manufacturing operations, auto repair shops, power tool use at residences and businesses, and a host of other activities associated with urban and suburban life. Some wastewater projects would contribute incrementally to this general pattern, especially during short- term construction activities. The City’s Noise Ordinance and Noise Guidelines Manual are designed to control the exposure of residents to excessive levels of noise. All CIP projects with a potential for long-term noise production would be evaluated for excessive noise generation and mitigation would be applied on a project-specific basis. Combined with regulation and attenuation of other sources consistent with the Noise Ordinance and Noise Guidelines Manual, the proposed Master Plan Updates’ contribution to cumulative noise impacts would be less than significant. July 2003 31 94-04 5-5 Carlsbad Water and Sewer Master Plan Updates - Program EIR Prof~irionnl Teonu bv Compla Propu 5.0 Cumulative Impacts Transportationflraffic As discussed in Section 4. IO, Transpurtution/Truffic, the proposed project components in the Master Plan Update would contribute to short-term impacts to traffic circulation on local roadways. Potentially significant cumulative traffic circulation impacts could result over the short-term if multiple projects were under construction simultaneously and in the same general location. Short-term traffic impacts caused by construction of the projects proposed within the study area would result from street closures, increased truck traffic, and disruption of local traffic to residences and businesses. As the CIP projects would be phased over a 20-year period and would not proceed simultaneously, it is anticipated that cumulative short-term impacts to project component roadways could be mitigated to a level of less than significant through coordination and implementation of traffic control plans at the time of construction with the City Engineering Department (for impacts to City roads) and with the planning entities for the Cities of Oceanside and San Marcos (for impacts to roads within their respective jurisdictions), Encroachment permits are required for all construction affecting public rights-of-way. This permitting process is the control point for the maximum possible reduction of cumulative traffic impacts, and is designed to reduce direct and cumulative impacts to below a level of significance. Utilities and Service Systems The proposed project components in the Master Plan Updates would not result in additional demands on utilities and services. Service providers have adopted plans to respond to future demands with system improvements. These plans are periodically updated based on both individual provider’s projections and SANDAG population forecasts. Therefore, this project in combination with other projects in the area would not have a significant cumulative impact on utilities and service systems.

As described in Chapter 4.0, potentially significant impacts would occur for the issue areas of Biological Resources; Cultural Resources; Geology and Soils; Hazards and Hazardous Materials; Hydrology and Water Quality; Noise; and Transportation/Traffic. As discussed in Chapter 4.0, mitigation measures would reduce impacts for all of these CEQA issue areas. With mitigation, the residual impact is less than significant for all issue areas. 6.2 SIGNIFICANT IRREVERSIBLE ENVIRONMENTAL CHANGES WHICH WOULD BE CAUSED BY THE PROPOSED PROJECT SHOULD IT BE IMPLEMENTED Water and sewer infrastructure components, once constructed, may be considered permanent. Occasionally facilities are abandoned/removed or upgraded once operation has resulted in the deterioration of their working condition. The systems for which water and sewer facilities are a part are integrally dependent on all their working components. Should components become deteriorated, malfunction or obsolete, replacement must occur. Because the implementation of many projects within the Master Plans would be implemented far into the future and because implementation and timing may affect land use decisions, adoption of the Master Plan Updates would leave the commitment of resources open in the future. The project components would support existing and planned growth within the City and Districts’ service areas. Where impacts are significant as defined by CEaA and the City, this Program EIR includes a process to identify and mitigate such impacts. Having said this, impacts such as changes in the visual appearance of a setting or hillside due to a pump station installation would be considered an irreversible change. Implementation of pipeline facilities within sensitive biological areas also may result in irreversible change to the hydrologic and biological environments of these sensitive areas. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 6- 1 6.0 Other Considerations Required by C€QA Construction of all project components would be carried out according to all applicable engineering stan’dards to reduce, as much as possible, accidents related to offsite runoff during or post-construction. It should be noted that accidents from both human and naturally caused situations can compromise the integrity of best management practice mitigation measures. For example, a severe storm of unprecedented level could impact the area; precautions included in the project to prevent damage from occurring as a result of this type of severe event may be compromised. Depending on the type of disaster and the resources impacted, significant irreversible environmental commitments of resources may occur. However, there will llkely be mitigation programs which can partially mitigate for large, unforeseen disasters. Following engineering standards set out in the Master Plan Updates is the best defense against an unforeseen event and therefore an unforeseen commitment of resources. Construction of water and sewer facilities involves the relatively permanent consumption of building materials such as pipeline components, wood for stability structures and energy for digging and earthmoving tasks. These resources, although at some extent in the long-term may be recycled, are considered to be permanently consumed. This type of commitment of resources is neither unusual nor unexpected given the nature of the facilities and is generally understood to be the tradeoff for benefits the system provides to the community. 6.3 GROWTH INDUCING IMPACT OF THE PROPOSED PROJECT Induced growth is that which exceeds the planned growth and results from new developments that would not have taken place in absence of the project. Growth inducement impacts can result in accelerated economic or population growth, or the construction of new housing, that either directly or indirectly resulted from building a project. Section 15126.2(d) of the CEaA Guidelines requires that EIRs discuss whether a proposed project could: “...foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding environment. Included in this are projects which would remove obstacles to population growth (a major expansion of a waste water treatment plant might, for example, allow for more construction in service areas). Increases in the population may tax existing community service facilities, requiring construction of new facilities that could cause significant environmental July 2003 3 1 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 6-2 - Profisaionol TL~U 10, Complu Pmpco 6.0 Other Considerations Required by C€QA c c I c c effects. Also (the environmental analysis must) discuss the characteristics OF some projects which may encourage and facilitate other activities that could signiFicantly affect the environment, either individually or cumulatively. It must not be assumed that growth in any area is necessarily beneficial, detrimental, or OF little significance to the environment.” The proposed project is the City of Carlsbad Water and Sewer Master Plan Updates, which is a multi-year master plan For Facility improvements within the CMWD and CSD. The Master Plan Updates include a review OF existing and projected flows, design criteria, capacity analyses, existing conditions assessment, and CIP. The improvement projects detailed in the CIP range from minor projects such as manhole replacements, to major infrastructure improvements such as replacement of a sewer main and installation OF a new water reservoir. The CIP includes 84 improvement projects to be built by 2020. Generally, growth-inducing projects possess such characteristics as being located in isolated, undeveloped or underdeveloped areas, necessitating the extension OF major infrastructure (e.g., sewer and water facilities, roadways, etc.), or those that could encourage “premature” or unplanned growth (Le., “leap-frog” development). While infrastructure improvements, like those planned in the Water and Sewer Master Plans’ CIPs, raises the issue OF growth inducement, the proposed project is not considered to be growth inducing because the proposed project would not provide additional long-term employment opportunities, no residences are planned as part of the proposed project, and no extension OF services beyond that currently planned For in respective planning documents (e.g., City OF Carlsbad General Plan) is associated with the proposed project. In calculating flow projections for the project, the Master Plan Updates relied on recent regional population projections published by SANDAG. The ultimate Flow projections were based on existing unit flow generation rates which were then applied to SANDAG 2020 population projections. ThereFore, the CIP projects would not generate additional population or cumulatively exceed official regional or local population projections. In addition, because no unplanned growth would be served by the project, the project would not remove an obstacle to growth. The facilities in the proposed Master Plan Updates are community service facilities, serving an urban infrastructure necessary to support economic and population growth. Their size and capacities are predicated on the projected growth that relates to the type of land use and the SANDAG population estimates and projections (SANDAG 2020 Cities/County Forecast). For that reason, the facilities in the Master Plan Updates would not induce growth guided by the City’s planning documents. July 2003 31 94-04 Carlsbad Water and Sewer Master Pian Updates Program EIR 6-3 6.0 Other Considerations Required by C€QA 6.4 EFFECTS NOT FOUND TO BE SIGNIFICANT The CEQA Guidelines (5 15128) require that the environmental document include a brief discussion of various environmental issues that were determined not to be significant. This Program EIR addressed all probable or foreseeable possible effects of the proposed project. Based on the discussions presented in Chapter 4.0, effects were not found to be significant for the following issue areas: Aesthetics; hr Quality; and Land Use and Planning. Based on the public scoping process for this project (refer to Section 4.3.4), the following issue areas were not considered to be areas of controversy, and were not addressed in Chapter 4.0 of the EIR. Hence, an evaluation of Agricultural Resources, Energy Resources, Population and Housing, Public Services, Recreation, and Utilities and Service Systems, those issues not addressed in Chapter 4.0 of this Program EIR, follows. Agricultural Resources Agriculture is an important resource in Carlsbad. The City has several agricultural policies in place that are intended to support agricultural activities while planning for the possible future transition of the land to more urban uses consistent with the policies of the General Plan and the Carlsbad LCP. The City’s LCP protects agricultural lands from the premature conversion to more urban land uses by establishing programs which require mitigation for conversion of agricultural property to urban uses. As stated in the Open Space and Conservation Element of the City’s General Plan, it is the City’s intention to support and utilize all measures available to secure agricultural land uses for as long as possible prior to development, and to promote the long-term economic viability of agricultural uses. However, the projected pattern of development in Carlsbad is such that the extensive areas generally required for economic agricultural operations are unlikely to be available in the long-term. In many cases, the agricultural use of property is an interim or transitional use due to economic factors and the ultimate development potential of a parcel. There are only a limited number of areas within the City that are considered to possess important farmlands as defined by the California Department of Conservation. The City consists mainly of Urban and Built-up Land along the western, southern, and northwestern portions of the City, with large areas of Other Land interspersed throughout the eastern and central portions. Implementation of the two Master Plan Updates will not result in significant impacts to agricultural resources. The project, located mostly within existing or future streets and disturbed areas, would not result in - July 2003 31 94-04 -- Carlsbad Water and Sewer Master Plan Updates Program EIR 64 c 6.0 Other Considerations Required by C€QA the conversion OF important Farmlands to non-agricultural uses, and will not conflict with any Williamson Act contracts in the City. c Energy Resources The projects proposed in the two Master Plan Updates would not significantly aFfect local or regional energy supplies, nor would the projects conflict with adopted energy conservation plans. The proposed power-consuming Facilities (Le., pump stations and lift stations) would incorporate new energy-efficient technologies, which utilize non- renewable resources in an eFFicient manner. Energy consumption From construction- related activities necessary For development OF the proposed Facilities would be relatively minor and impacts would not be signiFicant to existing energy resources. For some project components, use OF SDGE's rights-OF-way may be required. In these instances, coordination would be made with SDGE to ensure that the utility provider would be able to adequately access their Facilities. It is not anticipated that relocation OF any SDGE facilities is required For implementation OF the various water and sewer project components. Nonetheless, access and potential relocation issues, as well as grading or encroachment into SDGE rights-of-way, would be determined at the project level of analysis For each project component. Impacts would not be signiFicant at this program level OF analysis. Population and Housing The proposed Master Plan Updates would extend and improve existing water supply and sewer inFrastructure within the City in accordance with regional population projections and as needed by the demand that the Forecasted additional population would place upon these services. The proposed projects would be phased so that the inhastructure would be developed concurrently with the increased housing demand and population. The Master Plan Updates would not result in significant impacts to the City's projected population and housing needs. Public Services The implementation OF the Master Plan Updates would not require new services For the Following: Fire protection, police protection, schools, parks, or other public Facilities; no impact would occur. Emergency access would not be significantly a€Fected, as described in Sections 4.10.3 and 4.10.4. 3 1 94-04 6-5 July 2003 Carlsbad Water and Sewer Master Plan Updates Program EIR Rofcsml Teom fm Cornpla Pm)errr 6.0 Other Considerations Required by C€QA The project would not affect existing primary and secondary schools within the area. Implementation of the project in the manner or location planned would not result in impacts to proposed ‘schools. Additional demands on existing public parks would not occur. New or improved park facilities would not be necessary as a result of implementing the project. The proposed project would not exceed official regional or local population projections. The size, capacity, and location of all facilities would be based on the population and land use analysis contained in the Master Plan Updates which, in turn, is based on forecast growth identified in the City of Carlsbad General Plan, and systems would be sized appropriately to serve projected service populations. Recreation Implementation of the Master Plan Updates may cause potential conflicts with existing parks or recreational uses where facilities are proposed adjacent to these facilities. Potential conflicts with these types of facilities will be identified in the engineering and design stage of all phases of the project. The Districts are both obligated to coordinate all construction, repair, and maintenance activities with all park and recreation agencies whose facilities may be affected in the planning stage. Consequently, the required coordination with the affected agencies would reduce the potential conflicts to a less than significant level. The project would not result in increased demand for recreational uses, or prevent access to parks or recreational facilities. Utilities and Service Systems The proposed projects to be developed with implementation of the two Master Plan Updates would not significantly affect utilities and service systems. The proposed facilities would not place substantial demands upon the City’s utilities such as power and natural gas. The project facilities’ impacts on the area’s communications systems would occur as necessary safety and operating measures. Overall, these would be short-term minor impacts. July 2003 31 94-04 Carlsbad Water and Sewer Master Plan Updates Program EIR 6-6 - Profrmonal Team fw Campln Rgcco c CHAPT€R 7.0 ALT€RNATiV€S CEQA Guidelines Section 15126(d)(2) states that the range of potential alternatives to the proposed project shall include those that could feasibly accomplish most of the basic purposes of the project and could avoid or substantially lessen one or more of the significant effects. CEQA specifically requires the discussion of a “no project” alternative. In addition, CEaA requires that a reasonable range of alternatives to the project be discussed, including alternative locations. The reasonable range is to include alternatives that focus on the mitigation or avoidance of significant effects associated with the proposed project, that permit a reasoned choice for the decision maker, and that are feasible. Section 15126(d)(5) states that among the factors which may be taken into account when addressing the feasibility of alternatives are site availability, economic viability, availability of infrastructure, general plan consistency, other plans or regulatory limitations, jurisdictional boundaries, and whether the proponent can reasonably acquire, control, or otherwise have access to the alternative site. The following discussion includes a ‘ho project” alternative. The objectives of the project are understood to be those described in the Project Description (Chapter 2) of this Program EIR. The objectives are to provide for the modifications and additions needed for the existing water and sewage distribution, collection, treatment, incorporating current population projections, planning criteria, and new information from specific development plans. The CMWD and CSD are the exclusive central agencies for the provision of water and sewer services, respectively, within their service areas. For the Master Plan Updates that are the subject of this Program EIR, alternative locations are not possible. However, the Master Plan Updates are comprised of individual improvement projects and there are or may be possible variation in the size, phasing, location, and implementation of many of the individual projects, especially in the plans, later phases. For these reasons, no alternative location for the project is herein considered, but a discussion of the variability of individual project alternatives, in the context of the existing and planned systems, is included. The Master Plan Updates are guidance documents for the adequacy, continued operation, and expansion of systems that are, for the most part, already in place. The project components are designed to correct deficiencies in the existing system and to provide the new facilities that will be needed to accommodate growth and land use changes in the city at the appropriate time. Because this is the case, it is not reasonable to propose alternatives that would construct entirely new systems, and clearly no alternative July 2003 3 1 94-04 7-1 Carlsbad Water and Sewer Master Plan Updates Program EIR 7 .O AI ter natives location For the system is Feasible. Therefore, the discussions in this section are restricted to the No Project alternative required by CEQA, and to the possible changes to individual projects in the Master Plan Updates that could occur in response to changing conditions in the City’s growth. The environmentally superior alternative is also discussed as required by CEQA. 7.1 NO PROJECT ALTERNATIVE Under the No Project alternative, the proposed Water and Sewer Master Plan Updates would not be adopted by the City OF Carlsbad. This does not mean, however, that the Facilities in the Master Plan Updates or other Facilities based on development and need in the city, would not be constructed. All projects in the Master Plan Updates could be constructed or implemented on an individual project basis whether or not the Master Plan Updates are adopted. Potential environmental impacts identified in this Program EIR would still be likely to occur. This alternative would, however, deprive the City of Carlsbad of a valuable planning tool, and one that is informative for those interested in the City’s future plans and Facilities. Many OF the projects in the Master Plan Updates are intended to remedy deficiencies that were identified in the modeling of the City’s water and sewer systems or to correct problems or potential problems in the operation OF that system. IF the Master Plan Updates were not adopted, the deFiciencies and potential problems would remain and would still require remedy through, in most cases, the improvement projects that make up the integrated programs in the Master Plan Updates. Likewise, the new projects in the plans are predicated on the improvements needed to make the system adequate to serve the City’s planned future growth. Under the No Project alternative, the same improvements would likely be brought forward for approval as individual projects, but in piecemeal Fashion and not as an integrated program that had been evaluated as a single environmental project. In addition, the No Project alternative would deprive the City of the opportunity to streamline environmental review OF Future projects through the use of the Program EIR and subsequent updates. For these reasons, the No Project alternative offers no environmental advantages in either procedures, impacts, or public information over the proposed Master Plan Updates. 7.2 PLANNING AND LAND USE ALTERNATIVES The Water and Sewer Master Plan Updates were developed using the best available information on population growth; proposed, planned, and Forecast growth and development; means of effluent disposal; requirements and recommendations For peak July 2003 31 94-04 7-2 c 7 .O AI ternatives flows, volumes, and facility capacities; and other factors affecting future City water and sewer utilities planning. The planning period for the Master Plan Updates is long-term, extending to 2020, and almost all the factors in such long-range planning are to some degree uncertain. Most land use planning, until projects are implemented as buildout of the City proceeds, is subject to change for a variety of reasons. Thus, the Districts’ staff will continue to monitor factors likely to affect land use in the City and identify changes that could affect the forecasts and assumptions used to develop the improvement programs in the Master Plan Updates. Most of the projects in the Master Plan Updates are upgrading and modification of existing facilities. In such cases, the location of the project is usually fixed. Nonetheless, adjustments are possible because the Master Plan Updates are guiding documents rather than rigid templates. Flexibility in the implementation of the Master Plan Updates will occur at a specific project implementation level. Partly as a result of the mitigation program in this Program EIR, evaluation of the individual projects in the Master Plan Updates can occur at the stage of project approval or implementation. Given the speculative and to some degree uncertain nature of future conditions, this process is the only practical way to assure that feasible alternatives to each project, if desirable or necessary, are developed. As an example, if development plans approved for a given area change the street pattern in that area, the location of pipelines projected in the Master Plan Updates may change. If density or type of development in a given area changes, the storage capacity needed to serve that area, and thus the size of water reservoirs may change, and the capacity of sewer collection facilities may also change. Individual project review in the planning stage is the only time an informed decision on such matters can occur. 7.3 ENVIRONMENTALLY SUPERIOR ALTE RNATIVE As analyzed in Section 7.1, the No Project alternative would not result in reduced environmental effects when compared to the proposed project. The proposed project would result in the same or less impacts when compared to the No Project alternative because of its comprehensive program to identify, avoid, and minimize impacts to environmental resources in the overall study area. As such, the proposed project is considered to be the environmentally superior alternative.

HOLZhILLk&, Planning Director I Date Reference California Administrative Code, Title 14, (CEQA Guidelines) section 15082(a), 15103, 15375 Revised October 1989 ~~ ~~~ PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS 1 .o INTRODUCTION The Carlsbad Municipal Water District and City of Carlsbad Sewer District are responsible for the respective maintenance, operations, and management of water distribution and sewer collection systems in the City of Carlsbad (City). Each District proposes to implement a Master Plan Update for the provision of infrastructure services throughout the City. The two Master Plans, a Water Master Plan and a Sewer Master Plan, represent comprehensive programs for the phased and orderly development of water and sewer utilities for future needs of the City. They consist of individual capital improvement projects to construct new facilities and modify or expand existing facilities that would be needed to implement the Master Plans. 1 .I Lead Agencies 1.1.1 Carlsbad Municipal Water District The Carlsbad Municipal Water District (CMWD) water service area covers approximately 85 percent of the City and includes an area of approximately 32 square miles. Primary land uses in the service area include industrial, residential, and agricultural uses. All of CMWD’s water is supplied through four San Diego County Water Authority (SDCWA) treated water aqueduct connections. The CMWD is totally dependent on the SDCWA supply for potable water needs. Storage is provided by 11 enclosed reservoirs, one reservoir not in use, and one dam (Maerkle Dam). CMWD’s water distribution system includes over 230 miles of distribution mains 6 inches in diameter and larger. The water mains begin at each of the four SDCWA connections and move westward. In addition, four booster pump stations exist in the CMWD system, although one is inactive, Other components within the CMWD system include pressure reducing stations, a number of water wells, a hydro generation facility at Maerkle Reservoir, and two disinfection facilities. 1.1.2 Carlsbad Sewer District The Carlsbad Sewer District (CSD), previously known as the Carlsbad Sanitary District, provides sewer service to the Carlsbad area. Portions of the City’s existing convepance system date back as far as 1929. The CSD wastewater service area covers approximately 70 percent of the City limits. Sewer service to the southeast corner of the City of Carlsbad Water and Sewer Master Plans Page 1 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS City is provided by the Leucadia County Water District (LCWD), and the Vallecitos Water District (VWD) provides service to the Meadowlark area along the eastern City limit. The service area is comprised of five major drainage basins, which extend from approximately the eastern service area boundary, and drain west to the coast and ultimately to the Encina Water Pollution Control Facility (WPCF). These sewage drainage basins are defined by the existing and planned interceptors within the City of Carlsbad. In addition to the gravity interceptors, a number of lift stations are required to convey wastewater flows to the Encina WPCF. - r 1.2 Previous Master Plans Master planning for water and sewer infrastructure has been conducted previously in the City. The current plans represent updates to previous master planning documents. Summaries of recent Water and Sewer Master Plans are provided below, followed by a description of the current updates. 1.2.1 Previous Water Master Plans The original Water Master Plan was approved in 1990 and prepared by MacDonald- Stephens Engineers. A subsequent update, prepared in 1997 by ASL Consulting Engineers, revised and updated population projections, City planning criteria, and specific project development plans. The 1997 Master Plan Update identified the facilities required to serve existing and projected potable water demands within the service area and adjacent areas of influence. The 1997 document was not formally adopted by the City of Carlsbad, and as such, the recommendations made in the 1997 Update have been incorporated into the current 2003 Master Plan Update and will be evaluated in the CEQA document. 1.2.2 Previous' Sewer Master Plans 7987 Master Plan of Sewerage The 1987 Master Plan of Sewerage was prepared by Wilson Engineering and was the first plan prepared in accordance with City of Carlsbad Growth Management Plan. In 1987, the majority of development in Carlsbad was along the coastal strip and was City of Carlsbad Water and Sewer Master Plans Page 2 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS - predominantly residential. The population of the 1987 study area was estimated at 39,000, and the ultimate population was projected to be 95,700. In 1987, the ultimate average flow from the City of Carlsbad was projected to be 13.41 million gallons per day (mgd). - - 3 1992 Master Plan of Sewerage The 1992 Master Plan of Sewerage was prepared by Wilson Engineering and was an update of the 1987 Master Plan. By 1992, the population of the study area had increased to 65,000 and the ultimate population projection had increased to 130,000. Development was starting to progress inland and the percentage of commercial/industriaI development had increased since the last Master Plan. The projected population growth curve first developed in the 1987 Master Plan was revised to increase more rapidly through the year 2000, and then flatten out to an annual growth rate of approximately 1 percent from the year 2000 to buildout. In 1992,'the ultimate average flow projection was increased slightly from the 1987 projection to an estimated flow of 13.84 mgd. A CEQA Negative Declaration was prepared for this document, addressing the environmental effects of the Master Plan of Sewerage. 7997 Sewer Master Plan Update In 1994, the City of Carlsbad adopted a new General Plan. The 1997 Sewer Master Plan Update, prepared by Carollo Engineers, incorporated the revised 1994 land use and population projections from the new General Plan. Because ultimate population projections were reduced only slightly from those used in the previous plan, an updated capacity analysis of sewer interceptors was deemed unnecessary. The 1997 update addressed capacity analyses for various sewer trunk lines and the Encina WPCF. Similar to the 1997 Water Master Plan Update, the 1997 Sewer Master Plan Update was not formally adopted by the City of Carlsbad. The recommendations made in the 1997 Master Plan Update have been incorporated into the current 2003 Master Plan Update and will be evaluated in the CEQA document. 1.3 Purpose and Scope of Current Master Plan Updates The current Master Plan Updates for Water and Sewer are being assembled using the - following assumptions, data, and methods: - City of Carlsbad Water and Sewer Master Plans Page 3 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS I I ! I 1 I Inventorying data of existing facilities; Examining water billing records for existing development; Employing the City’s Growth Management Database for future development projections; Applying unit factors for demand; Using models for future infrastructure needs and sizing; and Calculating fees derived based on estimated construction costs. The Master Plans consist of multi-year studies for facility improvements within the Districts, and identify infrastructure needs to accommodate demands from future development through City buildout. The plans include a review of existing and projected flows, capacity analyses, existing conditions assessment, Capital Improvement Program (CIP), and revisions to the sewer and water connection fee programs. They would establish a connection fee program to fund buildout water and sewer infrastructure identified as part of the planning process. Therefore, three actions are included in the overall project: adoption of the two Master Plans and adoption of the connection fee program. The connection fee program would result in economic effects in that it would update the fee structure used to obtain funds for capital projects. As such, the connection fee program is not subject to the California Environmental Quality Act and will not be discussed in the EIR. ’ 1.3.1 2003 Water Master Plan Update The 2003 Water Master Plan Update (DUDEK 2003) evaluates the existing water distribution system and its ability to meet project demands. Since the most recent Master Plan Update in 1997, a substantial number of residential, commercial, and industrial developments have been constructed and future development has been identified in the City’s 2001 Growth Management Database. The 2003 document presents an update of CMWD’s Water Master Plan for the planning period between 2001 and buildout of the District’s service area, which is anticipated to occur by 2020. Based on the condition of many existing facilities, CMWD reviewed all infrastructure within the service area to identify necessary improvements to existing facilities, capacity improvements, and expansion needs. As stated in Section 1.2. I, the CIP developed in the 1997 Update is included in the 2003 Master Plan effort. City of Carlsbad Water and Sewer Master Plans Page 4 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS 1.3.2 The 2003 Sewer Master Plan Update (DUDEK 2003) represents an update of the District’s Sewer Master Plan for the planning period beiween 2001 and,buildout of the District’s service area (anticipated by 2020). In summary, the 2003 Update includes tasks to document existing facilities, project ultimate average wastewater flows, estimate existing and ultimate peak flows, and develop a computer model to perform an existing and ultimate system capacity analysis. The outcome of these analyses is a recommended long-term CIP for improvement of existing wastewater collection and treatment facilities. The 2003 Update also recommends a sewer connection fee to finance the recommended facilities. 2003 Sewer Master Plan Update In the 2003 Master Plan Update, ultimate sewer flow projections are based on the City’s recently compiled Growth Management Database, which projects the number of additional single and multi-family units and the number and size of non-residential buildings at buildout. 1.4 Project Description and Objectives The CMWD and CSD each propose to implement a master plan for the provision of infrastructure services throughout the City. The purpose of the Water Master Plan’is to make facility upgrades and increase capacity for the distribution of potable water; the Sewer Master Plan would update the City’s sewer collection facilities. CMWD and CSD propose to implement the plans in order to identify needed infrastructure, make facility improvements on aging infrastructure, increase capacity for identified expansion needs, reduce maintenance costs, and in the case of the Sewer Master Plan, reduce the potential for wastewater overflows. The CMWD Board of Directors is the decision-making body for the CMWD. The Carlsbad City Council is the decision-making body for the CSD. Together, CMWD and CSD will be Co-Lead Agencies in preparing this Program Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act of 1970 (CEQA) statutes (Cal. Pub. Res. Code, 5 21000 et seq., as amended) and implementing State CEQA Guidelines (Cal. Code Regs., Title 14, 5 15000 et seq., 1998). City of Carlsbad Water and Sewer Master Plans Page 5 c PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS Use of the Program NR A Program EIR is proposed to analyze the first-tier effects of the Water and Sewer Master Plan Updates. A Program EIR is typically used for an agency program or series of actions that can be characterized as one large project. Typically, such a project involves actions that are closely related geographically (Cal. Code of Regs., Title 14, 5 151 68(a)(l)), for agency programs (5 151 68(a)(3)), or as individual activities carried out under the same authorizing statutory or regulatory authority and having generally similar environmental effects which can be mitigated in similar ways (5 151 68(a)(4)). Program ElRs generally analyze broad environmental effects of the program with the acknowledgment that site-specific environmental review may be required for particular aspects of portions of the program when those aspects are proposed for implementation (5 151 68(a)). Once the Program EIR is prepared for the Water and Sewer Master Plans, subsequent (or second-tier) activities within the program must be evaluated to determine whether an additional CEQA document needs to be prepared. When the subsequent activities involve site-specific operations, the City would use a written checklist to document its determination that the environmental effects of the operation were covered in the Program EIR. If the Program EIR addresses the program’s effects as specifically and comprehensively as possible, many subsequent activities could be found to be within the Program EIR scope and additional environmental documentation would not be required (5 151 68(c)). If a subsequent activity would have effects that are not within the scope of the PEIR, the City would need to prepare a new Initial Study leading to either a Negative Declaration, Mitigated Negative Declaration, or an EIR. 1.4.1 Project Location The project is located in the northern part of San Diego County within the City of Carlsbad as shown in Figure 1. All project components would be located within the Districts’ boundaries, with two exceptions, as shown in Figure 2. A proposed water line upsize at the eastern end of Palomar Airport Road (component 26) would be located within the City of San Marcos, and the abandonment of nine ‘water wells is proposed (component 32) near Foussat Road within the City of Oceanside.

The project components are detailed in Attachment I, including their location, description, and project type. Water Pipelines and Mains A large majority of the CIP pipeline and water main projects proposed under the Water Master Plan Update would be financed via development fees from private developers as part of separate development projects throughout the City. As such, many of the water pipelines and water mains have been previously documented in separate CEQA documents such as EIRS, Mitigated Negative Declarations (MNDs), or Negative Declarations (NDs) as part of those development projects. A number of mixed use and residential development projects proposed by other parties have included water line upgrades and capacity analyses as part of those projects, in order to analyze whether adequate water supply would be available to their proposed developments. As such, a number of water lines have been discussed and analyzed in separate CEQA documents, which are available for review at the City of Carlsbad Planning Department. As indicated on the map, the dashed lines indicate water lines that have been previously addressed in a separate CEQA document, or are currently being reviewed in a separate CEQA document. These include facilities that will be provided or have - - City of Carlsbad Water and Sewer Master Plans Page 9 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS already been installed by private developers as part of various developments. The solid pipelines are those that are proposed as part of the 2003 Master Plan project. Attachment 2 provides additional detail regarding prior Dr current envirofimental review of pipelines shown on the map. Water Storage Two new water storage tanks are proposed to accommodate water supply needs. The first tank, component 27, is proposed at the existing water tank farm along Black Rail Road near its intersection with Poinsettia Lane. This tank would be approximately 175 feet in diameter, 56 feet high, and would be the fourth tank at that facility. The proposed tank would be the same size as the three existing tanks, approximately 8.5 million gallons. The second proposed water tank, component 28, would be a 15-million-gallon facility at Maerkle dam to supplement existing dam storage. It is proposed to be buried and would be approximately 350 feet wide and 110 feet high. Improvements to the existing reservoir at Lake Calavera (component 33) are also included in the Master Plan, and will be analyzed in a separate CEQA document. Pressure Reducing Stations A PRS provides a method of serving water between different pressure zones, from a higher pressure zone to a lower. Four new stations are proposed under the 2003 Master Plan Update. The size of the pressure reducing stations has not yet been determined, but each would be approximately 8 by 12 feet and could possibly be located underground. The facilities would include sump pumps and pressure reducing valves. Two of the stations (components 6 and 35) would be located within the Calavera Hills Master Plan area, near future Cannon Road east of El Camino Real. The third PRS (component 21) is planned for the southeast part of the City along El Fuerte Street, and the fourth (component 1) is located near future Marron Road in the northern section of the City. Also, one existing PRS (component 30) is proposed to be upsized with increased capacity to supply new development in the 375 zone. This PRS City of Carlsbad Water and Sewer Master Plans Page 10 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS is located east of El Camino Real just south of the Cantarini-Holly Springs residential development projects. Pump Stations - r One new pump station (PS) is proposed as component 20. It would be located at the northeast intersection of El Camino Real and Palomar Airport Road. The pump station would include three pumps and would roughly be 15 by 20 feet in size. Two PS projects (components 29 and 37) would involve conducting capacity improvements to existing stations. Component 29 is required for emergency supply from Maerkle Dam, and component 37 would also include installation of an emergency generator and other onsite improvements. . 1.4.3 Sewer Master Pian Update The 2003 Sewer Master Plan Update is to include capacity improvements to the existing sewer collection system’s wastewater interceptors. The components of the 2003 plan would involve rehabilitation or replacement activities for existing sewer pipelines and forcemains, improvements to existing lift stations, and removing several lift stations. Refer to Figure 2 for the location of these proposed facilities. The previously prepared Master Plan (Carollo 1 997) addressed improvements and capacity analyses of trunk sewers, and capacity summary of the Encina WPCF. NO CEQA documentation was prepared for the 1997 report; as such, the Program EIR will address the effects of implementing the projects recommended in the 1997 study, as well as impacts resulting from implementation of the 2003 Master Plan Update. Attachment 3 shows the proposed projects to be implemented as part of the 2003 project. VistdCarlsbad Interceptor Capacity Improvements As shown in Figure 2, projects proposed in the 2003 Sewer Master Plan Update’s recommended improvements include those related to the VistdCarIsbad Interceptor. The 2003 Update recommends replacement of existing interceptor lines with new 42- inch lines and replacing a parallel forcemain. These activities would all be conducted within existing alignments in roadways; no new lines are proposed. City of Carlsbad Water and Sewer Master Plans Page 11 PROJECT DESCRIPTION FOR THE CITY OF CARLSBAD WATER AND SEWER MASTER PLANS The existing Buena Vista Lift Station forcemain (component 30) consists of parallel 24-and 16-inch diameter pipelines for most of its length. It is recommended that a new 24-inch diameter forcemain replace the 16-inch main- and parallel the' existing 24-inch main for its entire length. In addition to increasing the station capacity, the new parallel forcemain will reduce peak velocities and increase reliability. Lift Stations c The 2003 Update recommends improvements to 8 existing sewer lift stations and the removal of 10 lift stations, as shown in Attachment 3 and Figure 2. At this program level of analysis, it is assumed that several lift stations would be physically removed rather than abandoned. As subsequent project-level plans become more defined, the CSD may determine to abandon some of the lift stations. Removal is generally a more impactive process on the environment that is abandonment, and as such, this Program EIR will analyze the worst-case scenario for purposes of environmental analysis. As part of the removal process, additional sewer lines are necessary to be installed in the immediate area surrounding the Gateshead, Villas, Woodstock, and La Golondrina lift stations to connect the sewer system to residential development projects. Other Lift Station Improvements Identified in the 7997 Master Plan c c A detailed survey of the sewer lift stations with respect to the condition, code compliance, standby power, and capacity was performed as part of the 1997 report. A summary of the recommended improvements that have not yet been constructed is provided in Attachment 3 and shown on the map on Figure 2. All of the recommended improvements would be installed within the footprints of the existing lift stations. Encina Water Pollution Con fro/ Facility Projects The 2003 Update includes a sewer connection fee update. The connection fee update includes 11 projects that would be implemented separately by the Encina Wastewater Authority (EWA) as lead agency. As one of six EWA member a.gencies, the City of Carlsbad is responsible to contribute their cost share of the proposed sewer projects, which would be funded in the connection fee program. The EWA projects are provided in this document to disclose the complete project description of the 2003 Update; however, EWA as lead agency is responsible for conducting separate environmental City of Carlsbad Water and Sewer Master Plans Page 12 PROJECT DESCRIPTION FOR THE CIN OF CARLSBAD WATER AND SEWER MASTER PLANS review for these projects, Refer to Attachment 4 for a list of the 11 EWA projects. All 11 projects are located on Encina WPCF property at 6200 Avenida Encinas.

When the Calavera Hills Treatment Plant was originally constructed, thsre was no provision for extending a gravity sewer line downstream of the plant. When the decision was made not to activate the plant, the sewer mains discharging into the plant site were connected to forcemaii pipe and sewage flows by gravity towards El Camino Real. The existing forcemain is not sloped properly to handle gravity flow and lacks the necessary access holes for proper maintenance. Removal of the existing forcemain and construction of a new gravity line will complete this portion of the sewer master plan.

As we have discussed previously, the project description does not mention the proposed desalination facility at the Encina Power Station or the offsite water lines that will be required for water produced by this facility. We understand that staff has concerns about providing a detailed discussion of this project and its offsite facilities in this EIR due to the City’s uncertainty about the future of the project and the size and location of the offsite facilities needed to serve it. However, we believe that the EIR for the City‘s Water and Sewer Master Plans should contain some discussion about this project addressing its potential impacts on Carlsbad’s water supply and explain that the desalination project and its offsite facilities are being addressed by a separate Environmental Impact Report. We are looking forward to the opportunity to review the draft EIR when it becomes available for public review later this year.

We were not provided a copy of the initial study for the project, so it is not clear to us whether and to what degree the City anticipates addressing cultural resources in the EIR. We would like to suggest that this is an appropriate time and level at which to define and adopt standard wording for archaeological monitoring of trenching and other excavation associated with individual projects. Components of such a monitoring program would include, but not necessarily be limited to, the following: Qualifications for project archaeologists and archaeological monitors Preconstruction meeting participation by the archaeologist Requirement for full-time presence of the archaeological monitor in the specified areas Actions to be taken in the event of discoveries Actions to be taken if human remains are encountered Requirements for collection processing, report generation, and curation at an appropriate institution * The City of San Diego has been heavily involved in water and sewer upgrades and replacements, which has led to development of comprehensive standard archaeological monitoring mitigation measures. We can provide a copy, or you may contact Ms. Myra Hemann at the City of San Diego’s Development Services Department, at (61 9) 446-5372. While modification would certainly be necessary to reflect the City of Carlsbad’s requirements and preferences, San I Diego’s efforts could serve as a good starting point. r I P.O.

Please note that Leucadia County Water District has recently changed our name to the Leucadia Wastewater District (LWD). LWD provides sewer service in the La Costa area of the City of Carlsbad. LWD, along with the City of Carlsbad (Carlsbad) are joint partners/owners in the Encina Wastewater Authority (EWA), which operates a regional wastewater treatment facility located in Carlsbad. We understand that Carlsbad is the lead agency for the Notice of Preparation and has requested the views of LWD as to the scope and content of the environmental information which is germane to LWD's wastewater agency responsibilities in connection with the proposed master plan water and sewer capital improvement projects. The proposed Carlsbad water and sewer projects will be located throughout the City of Carlsbad. It appears that only three of the proposed water projects and three of the proposed sewer projects are in the vicinity of existing LWD sewer facilities. In this regard, LWD requests that Carlsbad include LWD in the plan check process during the design and preparation of construction documents for these particular Carlsbad facilities. The project numbers and descriptions for which LWD requests notice and review are as follows: Water Emergency water booster pump in vicinity of Obelisco Place Provide redundant water supply at intersection of El Fuerte & Corintia St. Emergency water connection to SDWD along Carlsbad Boulevard F14 21 22 r Distritt Office: 1960 lo Costa Avenue, Corlsbod, (olifornio 92009-6B10 (760) 753-0155 *'Fax: (7601 753-3094 www.lcwd.org Printed on rnytkd popcr.

Mr. Paul Bushee, LCWD Assistant General Manager Mr. Frank Reynaga, LCWD I 1 A &Sernpra Energy utitity- May 28,2003 Ms. Elaine Blackburn City of Carlsbad Planning Department 1635 Faraday Drive Carlsbad CA 92008 RE: NOP OF EIR FOR THE CARLSBAD WATER AND SEWER MASTER PLANS - EIR 03-01 Ms. Blackburn: Sempra Energy Utilities, on behalf of San Diego Gas and Electric Company (SDG&E), is responding to a request from the City of Carlsbad for comments on the Notice of Preparation (NOP) for the Carlsbad Water and Sewer Draft EIR. As a property owner in the City of Carlsbad, and the provider of natural gas and electrical service to government, businesses and residents in Carlsbad, SDG&E supports the city in its efforts to provide reliable water and server service. Service Availability Electric and natural gas facilities can be made available to the project according to SDG&E’s rules filed with and approved by the California Public Utilities Commission (CPUC). However, the continued availability of electric and gas energy for this and future projects is dependent on the supply of fuel and other essential materials, and governmental approval of facilities construction. There are no general factors which can be applied to estimate the proposed electricity or gas demands for the lift stations, pumping stations, wells, hydro- generation or disinfectant facilities proposed for this project. Without detailed improvement drawings SDG&E cannot, at this time, determine the energy requirements for any electrical or natural gas system loads generated by the proposed water and sewer project. Therefore we are unable, at this time, to identify what if any relocations, changes or upgrades to our existing electric and gas transmission or distribution systems might be required to serve the project. However, SDG&E has customer project planners who can provide energy estimates, projected loads and the need for any potential system upgrades when detailed improvement drawings are available. Riahts-of Wav and Easements SDG&E needs assurance that access is retained to its existing utility rights-of- way and/or easements that may be affected by any of the proposed water and sewer system improvements or upgrades. Access to existing ‘rights-of-way and/or easements is critical to ensuring the continued maintenance, repair, upgrade, relocation or construction of SDG&E’s electrical and gas facilities. The DElR should address, where applicable, the effects of the project regarding: Any proposed relocations of existing SDG&E electrical or natural gas facilities within W, franchise positions, and/or easements required for the proposed water and sewer project. Proposed grading within any SDG&E (W) and/or easements. Proposed encroachments into R/W and/or easements and their potential impacts on existing SDG&E access road networks, including public or private roads. Increased drainage flow in WW and/or easements as a result of the proposed water or wastewater project improvements. Any proposed changes to land use in existing RM/ and/or easements as a result of the proposed project. Any changes to earth cover over existing underground natural gas lines or electrical distribution lines, or changes to aboveground clearances of existing overhead electrical lines. Water or sewer system improvements within or adjacent to SDG&E’s existing RNV and/or easements should consider information contained in SDG&E’s “Guide for Encroachment on Transmission Rights-of-way” and “Gas Transmission Mains Within SDG&E Easements, Restrictions for Encroachment into SDG&E Easements.” Copies of these documents can be obtained upon request. SDG&E typically requires the issuance of a Letter of Permission to Grade for grading within SDG&E W and/or easements. Encroachments or secondary uses within SDG&E W and/or easements typically require issuance of a Right of Way Use Agreement. t r Habitat and Endanqered SDecies c r r r r f Gas and electric transmission or distribution facilities provided to serve the proposed water and sewer project are defined .as customer projects under SDG&E’s existing Subregional Natural Community Conservation Plan (NCCP)/SO Year Permit. Therefore, any impacts to endangered species and/or their habitats resulting from gas or electrical service extensions and/or relocations for the proposed water and sewer project are not covered by the NCCP. It is important that any impacts to species or habitats as a result of extending or relocating gas or electrical service to the proposed water and sewer project are adequately discussed in the DEIR, and appropriate mitigation, environmental construction monitoring or post-project mitigation monitoring and maintenance for any project impacts are included and budgeted for in the city’s proposed water and sewer projects. Permittinq SDG&E’s electrical facilities are regulated by the CPUC under General Order 131-0 (GO 131-D). GO 131-D requires that SDG&E obtain permits for certain electrical transmission or substation projects. If the proposed water or sewer improvements discussed in the DElR require any relocation of electric transmission facilities over 50kV, and/or any new or upgraded electrical transmission or substation facilities in excess of 50 kilovolts (kV), permits for the construction of these facilities by SDG&E, may be required from the CPUC. The CPUC permitting process can take from 12 to 24 months. However, GO 131-D (Section A. and B.l) does grant exemptions from CPUC permits for certain electrical transmission line construction, extension or relocation and substation projects where they have “undergone environmental review pursuant to CEQA as part of a larger project, and for which the final CEQA document (Eiwironmeniai Impact Repori (EIR), or Negative Declaration) finds no significant unavoidable environmental impacts caused by the proposed line or substation.” To avoid any potential costly delays in permitting and construction of the proposed water and sewer facilities, we would encourage the City of Carlsbad to include discussion of such electrical facilities in the DEIR as necessary. f r 1. 7 SDG&E and Sempra Energy Utilities would like to thank you for the opportunity to comment on the draft master EIR.

Under 8 2800 - 9 2840 of the Fish and Game Code, the Depamntnt, through the NCCP program, is coordinating with locaI jurisdictions, landowners, and the Federal Government to preserve local and regional biological diversity. Coastal sage scrub is the first natural community to be planned for under the NCCP program. The Department recommends that the City ens re that the developmmt of this project docs not pncludc long-tcnn preserve plannine options, and that this project conforms with other requirements of the NCCP program and HCPIOMSP. Jurisdictions participating in the NCCP program should assess specific projects for consistency with the NCCP Conservation Guidelines, Additionally, the jurisdictions should quantify and qualify: 1) the amount of coastal sage scrab within their boundaries; 2) the acreage of coastal sage scrub habitat rernovcd by individual projects; and 3) any acreage set aside for mitigation.

The Department considers these communities as threatened habitats having 10th regional and local significance. Mitigation measures should emphasize avoidance, and where avoidance is ir feasible, reduction of project impacts. The Department generaHy does not support thc usc of docation, salvage, and/or transplantation as mitigation for impacts on rare, threatened. or endangered species. Studies have shown that these efforts an experimental 1 n naturt and largely unsucccssful.

The Water and Sewer Master Plans (WSMP) correspond to extensive programs of the development of water and sewer utilities for future needs of the City. These programs include individual capital improvement projects to construct new facilities and modify or expand existing facilities. As part of this Master Plan Update, a cultural resource background study was conducted to address the effects of the proposed capital improvement projects on cultural resource within or adjacent to the project components. The background study consisted of a literature review and record search, which identified 88 studies conducted within or adjacent to the project components of the WSMP. Primarily, as a result of these studies, 63 cultural resources were recorded. These cultural resources are typed as 9 habitation sites; 35 artifact scatters; 3 artifact scattedmilling stations; 2 lithic scatters; 5 shell scatters; 3 historic sites; 1 isolate; and 3 sites identified as unknown. The majority of the WSMP is within developed areas with only approximately 10% of the WSMP previously surveyed. For the WSMP, it is recommended that developed areas be spot-checked, and undeveloped areas not previously surveyed be surveyed to identify the presence or absence of cultural resources. Cultural resources identified as significant within or immediately adjacent to the WSMP components include: CA-SDI-628, CA-SDI-694, CA-SDI-5353, and CA-SDI-6826. Previously recorded cultural resources that have been evaluated for site significance and identified as not significant include: CA-SDI-209, CA-SDI-9473, CA-SDI-6819, CA-SDI- 11953, CA-SDI-15073, P-37-024171, P-37-024176, P-37-018284, and P-37-15325. In all, 50 previously recorded cultural resources have either not been tested or no information was available to determine site significance (see Table 3-1). Testing of these sites is recommended to determine site condition, significance and mitigation measures. If previously recorded sites are located within developed areas, monitoring during construction is recommended as an alternate to a testing program. If cultural resources are discovered as a result of monitoring, then testing and if necessary, data recovery will be conducted. r r PJ. 12-03 May 2003 iii SECTION 1 INTRODUCTION 1.1 PROJECT DESCRIPTION The Carlsbad Municipal Water District (CMWD) and City of Carlsbad Sewer District (CSD) propose to implement a Master Plan Update for provision of infrastructure services within the City of Carlsbad. The Water and Sewer Master Plans (WSMP) correspond to extensive programs of the development of water and sewer utilities for future needs of the City of Carlsbad (Figures 1-1 and 1-2). These programs include individual capital improvement projects to construct new facilities and modify or expand existing facilities. As part of this Master Plan Update, Gallegos & Associates was contracted by Dudek & Associates to conduct a cultural resource background study to address the effects of the proposed capital improvement projects on cultural resource within or adjacent to the project components. The goals of the WSMP Cultural Resource Background study are to: (1) Compile and review existing data for all project components; (2) Identify sites and site status within or adjacent to the project components; (3) Prepare a technical report which provides a description of the study results and a discussion of known and potential areas of cultural resource sensitivity; and (4) Recommend future compliance studies as components of the master plan. The approximately 153,240-foot linear project is located within the City of Carlsbad, and is depicted on the USGS San Luis Rey, San Marcos, Rancho Santa Fe, and Encinitas 7.5' quadrangles (Figures 1-1 and 1-2). All project components are located within the City of Carlsbad, with the exception of two additional areas, located at the eastern end of Palomar Airport Road and near Foussat Road (in the cities of San Marcos and Oceanside). The study was conducted in compliance with the City of Carlsbad and California Environmental Quality Act (CEQA) guidelines.

The environmental setting for the WSMP is framed by three major estuarine lagoons (Buena Vista Lagoon, Agua Hedionda Lagoon, and Batiq'uitos Lagoon) on 'the west, with two large canyons (Canyon de las Encincas and Los Monos Canyon) in between. In addition, three major drainage systems (Buena Vista Creek, Agua Hedionda Creek, and San Marcos Creek traverse the study area. Vegetation withm the study area includes coastal sage scrub, riparian habitat, oak woodland, and in disturbed areas or developed urban areas, non-native grasses and landscaped foliage are present. 1.3 BACKGROUND - PREHISTORY The body of current research of prehistoric occupation in San Diego County recognizes the existence of at least two major cultural traditions, discussed here as Early PeriodArchaic and Late Period, based upon general economic trends and material culture. Within San Diego County, the Archaic generally spans the period from 10,000 to 1300 years ago, while the Late Period spans from 1300 years ago to historic contact. The Historic Period covers the time from Spanish contact to present. 1.3.1 Early PerioaArchaic The Early PeriodArchaic, for this discussion, includes the San Dieguito and La Jolla complexes, which are poorly defined, as are the interrelationship between contemporaneous inland, desert, and coastal assemblages (Gallegos 1987). Initially believed to represent big game hunters, the San Dieguito are better typified as a hunting and gathering society. These people had a relatively diverse and non-specialized economy in which relatively mobile bands accessed and used a wide range of plant, animal, and lithic resources. Movement of early groups into San Diego County may have been spurred by the gradual desiccation of the vast pluvial lake system that dominated inland basins and valleys during the last altithermal period. This hypothesis is supported by the similarity between Great Basin assemblages and those of early Holocene Archaic sites in San Diego County. Several researchers recognized the regional similarity of artifacts and grouped these coftemporaneous complexes under the nomenclature of either the Western Pluvial Lakes r r PJ. 12-03 May 2003 1-4 Tradition or the Western Lithic Co-tradition (Bedwell 1970; Davis et al. 1969; Rogers 1939; Warren 1967; Moratto 1984). The origin of coastal populations and subsequent interaction between the coastal population and Great Basiddesert groups is a subject of some debate (Gallegos 1987). Whatever their origin, the first occupants immediately exploited the coastal and inland resources of plants, animals, shellfish, and fish (Moriarty 1967; Kaldenberg 1982; Gallegos 1991; Kyle et d. 1998). The development of a generahzed economic system indicates that the San Dieguito and related groups can be placed within,the general Archaic pattern. Archaic cultures occur withm North America at slightly different times in different areas, but are generally comlated with local economic specialization growing out of the earlier Paleo-Indian Tradition (Willig, Aikens and Fagan1988). Archaic cultures are often represented by more diverse artifact assemblages and more complex regional variation than occur in Paleo-Indian traditions. This is generally thought to have resulted from the gradual shift away from a herd-based hunting focus to a more diverse and area specific economy. The earliest sites are found near coastal lagoons and river valleys of San Diego County. These sites are the Harris Site (CA-SDI-149), Agua Hedionda Sites (CA-SDI- 210NCLJ-M-15 and CA-SDI-10695), Rancho Park North (CA-SDI-4392/SDM-W-49), and Remington Hills (CA-SDI-11069), dating from 9500 to 8000 years B.P. The northern San Diego County coastal lagoons supported large populations, circa 6000 years ago, as shown by the numerous radiocarbon dated sites adjacent to these lagoons. After 3000 years ago, there is a general absence of archaeological sites in north San Diego County to circa 1500 years ago. This reduction in number of archaeological sites can be attributed to the siltation of coastal lagoons and depletion of shellfish and other lagoon resources (Warren and Pavesic 1963; Miller 1966; Gallegos 1985). Archaeological sites dated to circa 2000 years ago are found closer to San Diego Bay, where shellfish were still abundant and may well represent what can be considered the end of the La Jolla Complex (Gallegos and Kyle 1988). The LA Jolla and Pauma complexes, which Complex, may simply represent seasonal or and more general San Dieguito Complex. are identified as following the San Dieguito geographic variations of the somewhat ofder Inland La Jolla occupation sites have been reported in transverse vaIleys and sheltered canyons (True 1959; Warren et al. 1961; PJ. 12-03 May 2003 1-5 r r i t r I i r Meighan 1954). These non-coastal sites were termed "Pauma Complex" by True (1959), Warren et al. (1961), and Meighan (1954). Pauma Complex sites by definition have a predominance of grinding implements (manos and metates), lack shellfish remains, have greater tool variety, seem to express a more sedentary occupation, and have an emphasis on both gathering and hunting (True 1959; Warren 1961; Meighan 1954). - r Archaic sites from 10,000 to 1300 years ago within San Diego County include coastal habitation sites, inland hunting and milling camps, and lithic quarry sites. Material cultural assemblages during this long period are remarkably similar in many respects. These deposits may well represent a process of relative terrestrial economic stability and presumably slow cultural change. Though various culture traits developed or disappeared during the long span of 10,OOO to 1300 years ago, there is a clear pattern of cultural continuity during this period. 1.3.2 Late Period During the Late Period (circa 1300 to historic contact), a material culture pattern similar to that of historic Native Americans first becomes apparent in the archaeological record. The economic pattern during this period appears to be one of more intensive and efficient exploitation of local resources. The prosperity of these highly refined economic patterns is well evidenced by the numerous KumeyaayDieguerio and Luiseiio habitation sites scattered over San Diego County. This ifcrease in Late Period site density probably reflects better preservation of the more recent archaeological record and a gradual population increase within the region. Artifacts and cultural patterns reflecting this Late Prehistoric pattern include small projectile points, pottery, the establishment of permanent or semi-permanent seasonal village sites, a proliferation of acorn milling sites in the uplands, the appearance of obsidian from Obsidian Butte, and interment by cremation. Many of the Late Prehistoric culture patterns in southern California were shared with groups along the eastern periphery of the region. Even in the most recent periods, the Native Americans of southern California incorporated many elements of their neighbors' culture into their own cultures. This transference and melding of cultural traits between neighboring groups makes positive associations of archaeological deposits with particular ethnographically known cultures difficult. This is particularly true of the groups within San Diego County. Though significant differences exist between Luiseiio and KumeyaayDiegueiio cultures (including linguistic stock), the long interaction of these PJ. 12-03 May 2003 1-6 groups during the Late Period resulted in the exchange of many social patterns. Archaeologists must rely heavily on ethnographic accounts of group boundaries as recorded during the historic period, although it is not known how long these boundaries had been in place or the validity of these boundaries as presently reported. The project area falls wihn Luiseiio territory as defined by Kroeber (1925). - r As a result of contact with Spanish, Mexican and American settlers, Native American populations were decimated by resettlement and disease. Presently, Native Americans are found throughout San Diego County, especially within the 17 San Diego County reservations. Further readings on Kumeyaay (Dieguerio) and Luiserio Native Americans include: Almstedt 1974; Barrows 1900; Bean 1972; Bean and Saubel 1972; Bums 1967; Cuero 1968; Drucker 1939; Dubois 1908; Gifford 1918; Harrington 1978; Hedges 1986; Heizer and Almquist 1971; Heizer and Whipple 1957; Hooper 1920; Keneally 1965; Kroeber 1970; Langdon 1970; Merrill 1973; Pourade 1960; Priestley 1937; Robinson 1969; Rudkin 1956; Shipek 1977, 1980, 1986a,b, 1987, 1988, 1989a,b, 1991, 1993; Sparkman 1908; Spicer 1962; Spier 1923; Strong 1929; Tibesar 1955; Underhill 1941; White 1963; Wolcott 1929; and Woodward 1934. 1.4 HISTORICAL BACKGROUND (taken from Gallegos et al. 1993) An abbreviated history of Spanish, Mexican and Amencan settlement in San Diego County is presented for the purpose of providing a background for discussion of the presence, chronological significance and historical relationship of historical resources within the project area. The history of San Diego County is commonly presented in terns of Spanish, Mexican and American political domination. A discussion of historic land use and occupation under periods of political rule by people of European and Mexican origin is justified on the basis of characteristics associated with each period, when economic, political and social activities were influenced by the prevailing laws and customs. Certain themes are common to all periods, such as the development of transportation, settlement, and agriculture. Robinson (1 979) provides a comprehensive account of public and privately owned land in California, with a discussion of laws, activities and events related to the development of the State. 1 7 '7 i 1 1 . I PJ. 12-03 May 2003 1 -7 r 1.4.1 Spanish Period (1769-1821) i r r r r r The Spanish Period represents: exploration; establishment of the San Diego Presidio, and the San Diego and San Luis Rey missions; the intrgduction of horses, cattle, and agricultural goods; and, a new method of building conStruction and archlectural style. Spanish influence continued after 1821, when California became a part of Mexico. Under Mexican rule, the missions continued to operate as in the past, and laws governing the distribution of land were also retained for a period of time. 1.4.2 Mexican Period (1821-1848) The Mexican Period includes the initial retention of Spanish laws and practices until shortly before secularization of the San Diego Mission in 1834, a decade after Spanish rule. Although several grants of land were made prior to 1834, vast tracts of land were dispersed through land grants offered after secularization. Cattle ranching prevailed over agncultural activities and the development of the hide and tallow trade increased during the early part of this period. The Pueblo of San Diego was established and transportation routes were expanded. The Mexican Period ended as a result of the Mexican-American War. 1.4.3 American Period (1848 to Present) The American Period began when Mexico ceded California to the United States under the Treaty of Guadalupe Kdalgo. Terms of the treaty brought about creation of the Lands Commission, in response to the Homestead Act of 1851, that was adopted as a means of validating land ownership throughout the state through settlement of land claims. Few Mexican ranchos remained intact because of legal costs and lack of sufficient evidence to prove title claims. Much of the land t'at once constituted rancho holdings became available for settlement by immigrants to California. The influx of people to California and the San Diego region was the result of various factors, including the discovery of gold in the state; the conclusion of the Civil War; the availability of free land through passage of the Homestead Act; and, later, the importance of the county as an agricultural area supported by roads, irrigation systems, and connecting railways. The growth and decline of towns occurred in response to an increased population and the economic boom and bust cycle in the late 1800s. , r r PJ. 12-03 May 2003 1-8 1.5 SUMMARY The approximately 153,240-foot linear WSMP cultural resource background study consisted of compilation and review of existing data for all project components, identification of sites and site status, discussion of known and potential areas of cultural sensitivity, and recommendations for future compliance studies.

The record search was conducted at the South Coastal information Center (SCIC), and Gallegos & Associates library. This study did not include fieldwork to determine the presence/absence of cultural resources or present condition of the sites within the WSMP. 2.2 LITERATURE REVIEW AND RECORD SEARCH METHODS A large map consisting of four 7.5’ USGS quadrangles (San Luis Rey, San Marcos, Rancho Santa Fe, and Encinitas) was created for the WSMP study area. This project map was then submitted to the SCIC, San Diego State University to identify previous work, previously recorded cultural resources, National Register listed and eligible properties (National Association of State Historic Preservation Officers et al., 1988 and annual updates in the Federal Register), California Historical Landmarks (Office of Historic Preservation 1990), Points of Historic Interest (Office of Historic Preservation, 1992), and locally listed historic properties and structures within the study area. Data gaps include the unevenness of the archaeological record and varied quality of the previously recorded cultural resource database. Some reports and site record forms were not included as they were reported missing by the SCIC. Previous work and site record information are discussed in the following sections.

This data was arranged by project component number, site number, site type, condition, recorder, date recorded, site comment, and type of study. For the present study, sites previously recorded within the WSMP were classified by type (Le., habitation, artifact scatter, and lithic scatter). The typing of sites was based, for the PJ. 12-03 2-2 May 2003 r r most part, on information provided on site forms. This information is often inconsistent and incomplete. When available, information from test and data recovery reports were used to supplement the database. Definitions for site types are provided below. Habitation Site: A habitation site contains a variety of artifacts, which may include flaked lith~cs, ground stone, ceramics, and ecofacts (i.e., bone and shell), as well as behock milling. The presence of some or all of these artifacts or features suggests that more than one activity occurred at the site. Habitation sites contain a midden deposit, suggesting seasonal or semi-permanent occupation. Artifacts Scatter: Artifact scatters are light-duty camp sites and are defined as surface scatters of a few artifacts, such as flaked lithics, tools, ground stone, and ceramics. Ecofacts such as bone and shell may also be present on this type of site; therefore, an artifact scatter may represent a stopping place on a journey, an area where a task was completed, or a special purpose site. This site type differs from a habitation site in that it does not contain a subsurface deposit (midden). Lithic Scatter: A lithic scatter is a scatter of debitage, cores, non-temporally diagnostic bifaces, and other flake- and core-based tools. For this study, such sites are presumed to lack diagnostic artifacts. Ceramic Scatter: A ceramic scatter is a scatter of native pottery sherds that represents a single vessel or multiple vessels, depending on specific variables (i.e., clay source). Ceramic scatters are temporally diagnostic, as native pottery was not introduced into the San Diego region until the late prehistoric period, after approximately 900 A.D. Shell Scatter: A she11 scatter is a scatter of fragmented or whole marine shell assumed to have a cultural affiliation. Milling Station Bedrock Milling): These are non-movable features located on large boulders or on bedrock outcrops that contain one or more milling features, such as mortars, basin metates, or milling slicks. A bedrock milling station is a specific task site; however, a surface andor subsurface deposit of artifacts may be present. If a complex archaeological assemblage is associated with a bedrock milling feature, then it is considered part of a habitation site. For this study, the term bedrock milling features are called milling stations. PJ. 12-03 May 2003 2-3 Ouq: This is a locality where the principle activity consisted of procuring rock for lithic tools. Quarry sites may be extensive and involve actual mining of lithic material, or they may be areas where cobbles from outcrops were tested for suitability (Wilke and Schroth 1989). Quarry sites do not usually contain artifacts associated with habitation, such as pottery, bedrock milling tooldfeatures, or faunal materid, although a limited number of processing artifacts may be present as support activity loci. For the purpose of this study, quarry sites are defined as localities where raw lithic material was obtained. Cobbles spread across Otay Mesa were not identified as quarries. Isolate Find: This is the occurrence of one or two artifacts and, by State of California definition, does not constitute a site. It should be noted that in the past some isolates have been given State of California site numbers. Rock Shelter: Often a small cave or overhang was used prehistorically for protection from inclement weather. Rock shelters usually contain a cultural deposit from the occupation and sometimes have pictographs or petroglyphs. Rock Feature: Rock features are identified as rock alignments, usually representing low- lying walls or rock piles. Traditional Cultural Property: This is a property that is eligible for inclusion in the National Register of Historic Places because of its association with cultural practices or beliefs of a living community that (a) are rooted in that community's history, and (b) are important in maintaining the continuing cultural identity of the community. The record search produced 63 cultural resources wihn or adjacent to the WSMP study area. These cultural resources were typed by Gallegos & Associates as: 9 habitation sites; 35 artifact scatters; 3 artifact scatterdmilling stations; 2 lithic scatters; 5 shell scatters; 3 historic sites; 1 isolate; and 3 sites identified as unknown. 1 1 1 I PJ. 12-03 May 2003 2-4 1 i r r r r r r r r r r 2.5 PREVIOUSLY RECORDED SITES WITHIN THE WSMP STUDY AREA a CA-SDI-209 Site CA-SDI-209 is within Sewer Project Component #3.

SECTION 3 SIGNIFICANCE CRITERIA AND RECOMMENDATIONS 1 3.1 INTRODUCTION This section provides guidelines and significance -criteria under the California Environmental Quality Act (CEQA) and the City of Carlsbad Guidelines. City guidelines identify the need for a record search, and field survey to identify the presence or absence of cultural resources. In order to comply with CEQA and City guidelines, a testing program to determine site significance is required. Testing programs provide the necessary information to more accurately determine site size, depth, integrity, and the quantity and range of cultural materia€ within a subsurface deposit. The testing program is also necessary to determine the potential for each site to address important research questions. The City of Carlsbad Cultural Resource Guidelines outline specific measures to conduct testing to determine site significance through documentation and evaluation of both surface and subsurface components of each cultural resource. If a site is recommended as not significanthot important under CEQA and city guidelines, then upon acceptance of the report by the agency, no further work is necessary and the site need not be addressed as to mitigation of impacts. The final report is submitted to the City of Carlsbad and to the local repositories at SCIC, San Diego State University, and the San Diego Museum of Man. If a site is determined to be significanthmDortant - under CEQA and City guidelines, several options determined by the local agency are available. For example, the site may be preserved and protected in an Open Space Easement and capped with soil. Certain uses may be allowed over a capped site, such as tennis courts, parking lots, golf course greens or parks. All artifacts collected as a result of survey, testing, data recovery, or monitoring need to be curated according to current professional repository standards. The collections and associated records shall be transferred to an appropriate facility within San Diego County. 3.2 SIGNIFICANCE UNDER CEQA < Determination of what is and what is not an important resource is not a straightfonvard task. As suggested by Moratto and Kelly (1976), the significance of archaeological resources 1 -7 1 1 PJ. 12-03 May 2003 3 -1 7 - I i r i r 1 i r r should be assessed in several tern, including research value to the scientist, aesthetic/ cultural value to the community at large, and value to the Native American community. The importance of an archaeological resource must be demonstrated. According to Section 15064.5 of CEQA, the term “historical resources” shall include the following: A resource listed in, or determined to be eligible by the State Historical Resources Commission, for listing in the California Register of Historical Resources (Pub. Res. Code $5024.1, Title 14 CCR, Section 4850 et seq.). A resource included in a local register of historical resources, as defined in Section 5020.l(k) of the Public Resources Code or identified as significant in an historical resource survey meeting the requirements Section 5024.1(g) of the Public Resources Code shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrate? that it is not historically or culturally significant. Any object, ouilding, structure, site, area, place, record, or manuscript which a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be an historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be “historically significant” if the resource meets the criteria for listing on the California Register of Historical Resources (Pub. Res. Code 55024.1, Title 14 CCR, Section 4852) including the following: (A) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; (B) Is associated with the lives of persons important in our past; (C) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or (D) Has yielded, or may be likely to yield, information important in prehistory or history. The fact that a resource is not listed in, or determined to be eligible for listing in the California Register of Historical Resources, not included in a local register of historical resources (pursuant to Section 5020.l(k) of the Public Resources Code), or identified in an historical resources survey (meeting the criteria in Section 5024.l(g) of the Public Resources Code) does not preclude a lead agency from determining that the resource may be an historical resource as defined in Public Resources Code sections 502O.lQ) or 5024.1. (b) A project with an effect that may cause a substantial adverse change in the significance of an historical resource is a project that may have a significant effect on the environment. PJ. 12-03 May 2003 3 -2 I (3) Substantial adverse change in the significance of an historical resource means physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired. The significance of an historical resource is materially impaired when a project: (A) Demolishes or materially alters in an adverse manner those physical characteristics of an hlstorical resource that convey its historical significance and that justify its inclusion in, or eligibility for, inclusion in the California Register of Historical Resources; or (B) Demolishes or materially alters in an adverse manner those physical characteristics that account for its inclusion in a local register of historical resources pursuant to Section 5020.l(k) of the Public Resources Code or its identification in an historical resources survey meeting the requirements of Section 5024.1(g) of the Public Resources Code, unless the public agency reviewing the effects of the project establishes by a preponderance of evidence that the resource is not historically or culturally significant; or (C) Demolishes or materially alters in an adverse manner those physical characteristics of a historical resource that convey its historical significance and that justify its eligibility for inclusion in the California Register of Historical Resources as determined by a lead agency for purposes of CEQA. Generally, a project that follows the Secretary of the Interior’s Standards for the Treatment of astoric Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings or the Secretary of the Interior’s Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings (1993, Weeks and Grimmer, shall be considered as mitigated to a level of less than a significant impact on the historical resource. A lead agency shall identify potentially feasible measures to mitigate significant adverse changes in the significance of an historical resource. The lead agency shall ensure that any adopted measures to mitigate or avoid significant adverse changes are fully enforceable through permit conditions, agreements, or other measures. When a project will affect state-owned historical resources, as described in Public Resources Code Section 5024, and the lead agency is a state agency, the lead agency shall consult with the State Historic Preservation Officer as provided in Public Resources Code Section 5024.5. Consultation should be coordinated in a timely fashion with the preparation of environmental documents. Recognizing that cultural resources often contain information that archival research cannot answer, there exists the potential for each resource to provide important information relevant to several theoretical and regional research questions. As part of the test plan, research questions concerning chronology, lithic technology, food procurement strategies, and trade 7 i 1 7 PJ. 12-03 May 2003 3 -3 7 1 and travel were addressed. Testing provided the necessary information to determine site size, depth, content, integrity, and potential to address important research questions. 3.3 IMPACTS To complete the impact analysis, WSMP Project Comp'bnents within developed areas should be spot-checked, and WSMP Project Components in undeveloped areas shouId be surveyed to identify the presence or absence of cultural resources. The impacts to the WSMP Project Components are summarized in Table 3-1. For this section, the following criteria are used to determine the significance of the resource, and evaluation and mitigation measures: Criteria for Determining Significance A project will normally have a significant impact if it will disrupt or adversely affect a prehistoric or historic archaeological site or a property of historic or cultural significance to a community or ethnic or social group; except as part of a scientific study. According to CEQA Guidelines, an important prehistoric or historic resource is one which: e e e e e 3.3.1 is associated with an event or person of recognized significance in California or American history, or recognized scientific importance in prehistory; can provide information which is both of demonstrable public interest and useful in addressing scientifically consequential and reasonable or archaeological research questions has a special or particular quality such as oldest, best example, largest, or last surviving example of its kind; is at least 100 years old and possesses substantial stratigraphic integrity; or involves important research questions that historical research has shown can be answered only with archaeological methods. Recommended Evaluation and Mitigation Measures The following recommended mitigation measures would reduce identified impacts to land-.use to less-than significant (Table 3- 1). [a] Obtain permission from private landowners to survey the fields and yards in order to determine presence/absence of cultural resources. If cultural resources are located then mitigation measure [b] is recommended.

Depending on monitoring results, testing and data recovery may be necessary to evaluate the resource and to mitigate the impacts. Test those sites that have not yet been tested so a determination of significance can be made. If the resource is determined to be significant, mitigate through avoidance. If avoidance is not feasible, then mitigation through a data recovery program (see mitigation measure [c]). If site avoidance, the preferred mitigation measure, is not feasible, then a data recovery program should be completed to recover a large enough sample of cultural material so that information of importance in addressing Fgional research questions will not be irretrievable lost through impacts. Provide a qualified archaeological monitor during construction so that buried cultural resources can be identified in the field. Upon identification, the resource should be tested (mitigation measure [b]) to determine significance with appropriate mitigation measures as necessary. Monitoring Program The evaluation and monitoring program will be used for cultural resources within the WSMP study area that are located within developed areas. For these sites, a monitoring program, rather than a test program, is recommended if construction is to occur within or adjacent to the cultural resource site. Components of such a monitoring program would include, but not be limited to the following (adapted from City of San Diego Guidelines): Prior to Preconstruction (Precon) Meeting (1) Planning Department (PD) Plan Check a. Prior to the first Precon Meeting, the Environmental Compliance OfficerPlanner (ECOP) of PD shall verify that the requirements for Archaeological Monitoring and Native American monitoring, if applicable, have been noted on the appropriate construction documents. Prior to the first Precon Meeting, the applicant shall provide a letter of verification to the ECOP stating that a qualified Archaeologist has been retained to implement the monitoring program. At least thirty days prior to the Precon Meeting the qualified Archaeologist shall verify that a records search has been completed and updated as necessary and be prepared to introduce any pertinent information concerning expectations and probabilities of discovery during trenching and/or grading activities. Verification includes, but is not limited to, a copy of a confirmation letter from South Coast Information Center or, if the search was in-house, a letter of verification from the Archaeologist stating that the search was completed. (2) Submit Letter of Qualification to ERM a. (3) Records Search Prior to Precon Meeting Precon Meeting 1. Monitor Shall Attend Precon Meetings a. Prior to beginning any work that requires monitoring, the Applicant shall arrange a Precon Meeting that shall include the Archaeologist, Construction Manager and/or Grading Contractor.

Identify Areas to be Monitored At the Precon Meeting, the Archaeologist shall submit to ECOP a copy of the sitdgrading plan (reduced to 11x17) that identifies areas to be monitored as well as areas that may require delineation of grading limits. During Construction 1. Monitor Shall be Present During GradingExcavation - r The qualified Archaeologist shall be present full-time during gradinglexcavation of native soils and shall document activity via the Consultant Monitor Record. This record shall be sent to the ECOP, as appropriate, each month. 2. Monitoring Trenches Will Include Mainline, Laterals, and all Appurtenances Monitoring of trenches is required for the mainline, laterals, services and all other appurtenances that impact native soils one foot deeper than existing as detailed on the plans or in the contract documents identified by drawing number or plan file number. It is the Construction Manager's responsibility to keep the monitors up-to-date with current plans. 3. Discoveries a. Discovery Process In the event of a discovery, and when requested by the Archaeologist, or the Principal Investigator (PI) if the Monitor is not qualified as a PI, the Construction Manager (CM), as appropriate, shall be contacted and shall divert, direct or temporarily halt ground disturbing activities in the area of discovery to allow for preliminary evaluation of potentially significant archaeological resources. The PI shall also immediately notify ECOP of such findings at the time of discovery. The significance of the discovered resources shall be determined by the PI. For significant archaeological resources, a Research Design and Data Recovery Program shall be prepared, approved by the agency and carried out to mitigate impacts before ground-disturbing activities in the area of discovery will be allowed to resume. Minor Discovery Process for Pipeline Projects For all projects: The following is a summary of the criteria and procedures related to the evaluation of small cultural resource deposits during excavation for pipelines. b. Determination of Significance C. (1) Coordination and Notification . (a) Archaeological Monitor shall notify PI, CM and ECOP, as appropriate. Criteria used to Determine if it is a Small Cultural Resource Deposit (a) The deposit is limited in size both in length and depth; and, (b) The information value is limited and is not associated with any other resources; and, (c) There are no unique featuredartifacts associated with the deposit. (d) A preliminary description and photographs, if available, shall be transmitted to ECO/P. (e) MMC will forward the information to EAS for consultation and verification that it is a small historic deposit. (3) Procedures for documentation, curation and reporting The following constitutes adequate mitigation of a small historic deposit to reduce impacts due to excavation activities to below a level of significance. (a) 100% of the artifacts within the trench alignment and width shall be documented in-situ, to include photographic records, plan view of the (2) PJ. 12-03 May 2003 3 -8 trench and profiles of sidewalls, recovered, photographed after cleaning and analyzed and curated. (b) The remainder of the deposit within the limits of excavation (trench walls) shall be left intact. (c) The Final Results Report shall include a requirement for monitoring of any future work in the vicinity. 4. Human Remains If human remains are discovered, work shall halt in that area and procedures set forth in the California Public Resources Code (Sec. 5097.98) and State Health and Safety Code (Sec. 7050.5) as follows: a. Notification (1) (2) (1) Archaeological Monitor shall notify the PI, CM and ECOP. The PI shall notify the County Coroner after consultation. CMIECOP, as appropriate, shall stop work immediately in the location of the discovery and any nearby area reasonably suspected to overlay adjacent human remains until a determination can be made by the County Coroner in consultation with the PI concerning the origin of the remains and the cause of death. (2) The County Coroner, in consultation with the PI, shall determine the need for a field investigation to examine the remains and establish a cause of death. If a field investigation is not warranted, the PI, in consultation with the County Coroner, shall determine if the remains are of Native American origin. b. Stop work and isolate discovery site (3) c. If Human Remains are Native American (1) The Coroner shall notify the Native American Historic Commission (NAHC). (By law, ONLY the Coroner can make this call.) NAHC will identify the person or persons it believes to be the Most Likely Descendent (MLD). The MLD may make recommendations to the landowner or PI responsible for the excavation work to determine the treatment, with appropriate dignity, of the human remains and any associated grave goods (PRC 5097.98). (2) (3) d. If Human Remains are not Native American (1) The PI shall contact the NAHC and notify them of the historical (2) (3) context of the burial. NAHC will identify the person or persons it believes to be the MLD . The MLD may make recommendations to the landowner or PI responsible for the excavation work to determine the treatment of the human remains (PRC 5097.98). If the remains are of historic origin, they shall be appropriately removed and conveyed to the Museum of Man for analysis. The decision for reinterment of the human remains shall be made in consultation with ECOP, the landowner, the NAHC and the Museum of Man. (4) e. Disposition of Human Remains The landowner, or his authorized representative, shall reinter the Native American human remains and any associated grave goods, with appropriate dignity, on the property in a location not subject to further subsurface disturbance, IF: (1) The NAHC is unable to identify the MLD, OR the MLD failed to make a recommendation within 24 hours after being notified by the Commission; OR; i 1 1 PJ. 12-03 May 2003 3 -9 t 1 I r r r r i r r r r r r r I r k r r (2) The landowner or authorized representative rejects the recommendation of the MLD and mediation in accordance with PRC 5097.94 (k) by the NAHC fails to provide measures acceptable to the landowner.. . 5. Notification of Completion The Archaeologist shall notify the ECO/P, in writing of the end date of monitoring. Post Construction 1. Handling and Curation of Artifacts and Letter of Acceptance The Archaeologist shall be responsible for ensuring that all cultural remains collected are cleaned, catalogued, and permanently curated with an appropriate institution; that a letter of acceptance from the curation institution has been submitted to the Planning Development; that all artifacts are analyzed to identify function and chronology as they relate to the history of the area; that faunal material is identified as to species; and that specialty studies are completed, as appropriate. Curation of artifacts associated with the survey, testing andlor data recovery for this project shall be completed in consultation with ECOlP and the Native American representative, as applicable. Final Results Reports (Monitoring and Research Design and Data Recovery a. Within three months following the completion of monitoring, two copies of the Final Results Report (even if negative) and/or evaluation report, if applicable, which describes the results, analysis, and conclusions of the Archaeological Monitoring Program (with appropriate graphics) shall be submitted to ECOP for approval. For significant archaeological resources encountered during monitoring, the Research Design and Data Recovery Program shall be included as part of the Final Results Report. r a. b. 2. fiogra b. 3. Recording Sites with State of California Department of Park and Recreation The Archaeologist shall be responsible for recording (on the appropriate State of California Department of Park and Recreation forms-DPR 523 A/B) any significant or potentially significant resources encountered during the Archaeological Monitoring Program in accordance with the City's Historical Resources Guidelines, and submittal of such forms to the South Coastal Information Center with the Final Results Report. 3.4 RECOMMENDED MITIGATION MEASURES The recommended survey, testing, and mitigation programs where necessary, for the sites with undetermined site status are based on CEQA and City of Carlsbad Guidelines (Table 3-1). For undeveloped lands, those project components, which have not been previously surveyed, and, due to the high sensitivity of prehistoric sites near lagoons, all project components within one-half mile of a lagoon will need to be surveyed to identify the presence or absence of cultural resources. For all sites located within undeveloped land, surface collections should be used to determine .the site limits and areas of artifact concentrations in order to ascertain placement of test units and shovel test pits (STPs) andor backhoe trenches. Excavation units (1x1-m) should be those areas where ground stone, fire-altered rock, or a concentration of flaked material occur. Backhoe trenching is PJ. 12-03 May 2003 3-10 recommended at those sites where deep subsurface deposits (i.e., historic privies or dumps or subsurface prehistoric deposits) are possible. For all sites located within developed land, a field visit to spot check the area, and a construction monitoring program are recommended. Monitoring is recommended for sites that have been previously addressed as to mitigation of impacts through a data recovery program, as additional unknown buried deposits may still be present. For the historic sites, the test program should include a literaturehistoric files review, mapping of any remaining structures, and mechanical backhoe trenching when applicable for determining the location of historic dumps. Mitigation through data recovery and all reports should follow City of Carlsbad 3.5 SUMMARY The literature review and record search identified 87 studies immediately adjacent to the WSMP study area. Data gaps include Guidelines (1980). conducted within the unevenness of or the archaeological record and varied quality of the previously recorded cultural resource database. Primarily as a result of these studies, 63 cultural resources were recorded within or adjacent to the WSMP study area. Of the 63 sites, a total of 33 sites have been recorded within the Water Project Components, and a total of 34 sites have been recorded within the Sewer Project Components. Nine sites were identified as not sigmficant, 4 sites were identified as significant, 48 sites were identified as unknown site status, and 2 sites were identified as unknown site status for portions of the sites. These cultural resources were typed by Gallegos & Associates as: 9 habitation sites; 35 artifact scatters; 3 artifact scatterdmilling stations; 2 lithic scatters; 5 shell scatters; 3 historic sites; 1 isolate; and 3 sites identified as unknown. Under CEQA and City Guidelines, impacts and mitigation of impacts cannot be addressed until site significance has been determined. Field surveys need to be conducted for those areas of undeveloped lands and spot-check field visits need to be conducted in developed areas within the Carlsbad WSMP study area to identify the presence or absence of cultural resources. Recommendations for sites that have not been tested to determine site significance are shown on Table 3-1. Sites that have been previously tested and identified as significant need to be addressed as to impacts and mitigation of impacts. Mitigation of impacts can be achieved through avoidance or through the completion of a data recovery program. Monitoring is recommended for sites within the WSMF, as well as sites that save PJ. 12-03 May 2003 3-11 r r r r r r r r r r r r r r r r r r r been previously addressed as to mitigation of impacts through a data recovery program, as burials may still be present.

However, the City of Carlsbad has elected to respond to the comments as part of the public review process of the Draft Program EIR. B-2 Build-out population projections and population distribution forecasts used for the Water and Sewer Master Plan Updates were based on the City's Growth Database, as described in Section 2.4 of the Draft Program EIR. Additional details on the Growth Database are provided below to address the public comment received on this topic. The information provided derives from the 2003 Water Master Plan Update and 2003 Sewer Master Plan Update prepared for the City by Dudek & Associates. Details regarding these plans can be found in Sections 2.4.1 and2.4.2 OftheDraftProgramEIR. The City's 2001 Growth Database is parcel-based and includes information on existing land use, as well as the future growth potential. The growth data, which is based on current development plans and results of the 2000 Census, consists of the number of projected single-family units, multi-family units, and the estimated building area for non-residential land use at build-out. Most of the projected growth in the CMWD and CSD is associated with known, planned developments in the eastern portion of the City. These developments include Kelly Ranch, Villages of La Costa, Calavera Hills, Mandana Properties, and Robertson Ranch, which are primarily residential developments, the Carlsbad Oaks North and Faraday Business Parks, and Bressi Ranch, which will have a mixed-land use. Development information for these large planned projects is typically lumped onto a single existing parcel in the Growth Database, even if the project boundary encompasses several existing parcels or pressure zones. The remainder of the future growth in the City of Carlsbad includes smaller, non- specific developments and general infill of established neighborhoods and commercial areas generally located in the western portionsbf the City. October 2003 3 RESPONSES TO COMMENTS + CITY OF CARLSBAD WATER 6t SEWER MASTER PLAN UPDATES PROGRAM EIR COMMENT8 813 8-4 RC8PON8E8 Several updates to the projected future growth in the Growth Database were provided by the City since the 2001 version, and the modified database was used as the basis for the Water and Sewer Master Plan Updates. The growth potential data in the City of Carlsbad Growth Database used for the Master Plan Updates is summarized by Local Facility Management Zone (LFMZ) in Table 1 below. Not all of the parcels included in the Growth Database are within the applicable service areas. For example, portions of LFMZ 6 are served by the Olivenhain Municipal Water District (OMWD) and all of LFMZs 11,12 and 23 are served by either the OMWD or the Vallecitos Water District, The CMWD ultimate water demand identified in the 2003 Water Master Plan was projected based on existing demands, future water demands calculated from the Growth Database, and future irrigation demands obtained from recycled water projections. In addition, the Water Master Plan Update in Chapter 6 states that “ultimate demand projections are to be based on the assumption that the planned Phase I1 expansion of the CMWD Recycled Water System is not constructed.” To estimate ultimate demands, demand projections for future development identified in the Growth Database and irrigation demands identified from the 1999 Recycled Water Master Plan were added to existing system demands. The ultimate potable water demands therefore exclude recycled water demands currently served by the CMWD Phase I Recycled Water System, but include the future irrigation demands identified in the CMWD Recycled Water Master Plan for the Phase I1 System. Future landscape irrigation for such uses as the irrigation of parks, playgrounds, golf courses, landscaped areas along freeways, green belts, and extensive common-area landscaping for industrial and commercial parks and subdivisions were not included in the 2003 Water Muster Plan Update projections. Demand projections for this type of water use are obtained from the City’s compilation of identified future Phase I1 Recycled water customers. The planned Phase I1 Recycled Water System will serve all the major new development areas within the CMWD potable water service area. However, the 2003 Master Plan Update did project the demand for the City municipal golf course in Table 6-4, which is approximately 384 acre-feet per year.

The Draft Program EIR text from Pages 1-5 and 1-6 is restated here for the sake of the commentor. It is beyond the scope of this EIR to analyze the potential desalination facility for several reasons. As one of the largest proposed desalination projects on the U.S. West Coast, it is uncertain whether the project would ever be constructed due to its location adjacent to sensitive coastal resources and high cost. The project considers several alternatives for pipelines and pump facilities throughout the City of Carlsbad and in adjacent jurisdictions, although the location and sizing of these facilities has not yet been decided. To determine impacts on water supply, more precise information on the proposed routing and size of these lines would be required. Also, it is unknown at this time whether the proposed desalination project would co-mingle desalinated water with other drinking water in the same pipelines, or whether new and separate pipelines would need to be constructed by the Authority. Further, the proposed desalination facility plans are still subject to change in the near future, making it infeasible for the Water and Sewer Master Plan Updates EIR analysis to remain current with the desalination facility plans. For these reasons, the project is considered to be highly uncertain, both in its totality and in the specific facilities which would be required (e.g., pipelines, pumps, other associated facilities). Thus, it would be infeasible to adequately analyze the desalination facility in this Master Plan program-level document. The desalination project is currently being analyzed in a separate project EIR being prepared by the Authority. Project-specific information regarding the size, location, and nature of the desalination facility including potential impacts to water supply, and appropriate alternatives will be analyzed in that document.

Federal General Codormitv Rule for the Federal Clean Air Ad lCAAl I I Fcdml clean air laws require that in Air Quality Maintenance District (AQMD) that has unhealthy levels of criteria pollulants, such as ozone, carbon monoxide, nitrogen dioxidq sulfur dioxide, and inhalable particulate matter, develop a State Implementation Plan (SIP) that describes bow the AQMD will attain national ambient air quality standards. Emission inventories can be obtained hm the AQMD. A CAA general wnformity analysis applies only to SRF funded 6j-s in an&ttainment area, or an attainment area subject to a maintenance plan, and is required for each criteria pollutant for which an area has been designated nonattainment or maintenance. If a project's emissions arc below the area's minimum threshold levels for critmia pollutants and an also less than ten percent of the area's inventory specified hr each criteria pollutant in a nonattainment or maintenance area, further general conformity analysis is not required.

Out of the total of 84 project components listed in the Water and Sewer Master Plan Updates, 58 would not result in significant biological impacts. The process of determining whether a project may result in significant biological impacts was pricnipally based on existing vegetation mapping, sensitive species locations, and aerial photographs. Although critical habitat was not directly analyzed, it is assumed that adverse modification would only occur where biological resources are affected. For the remaining 26 project components, the type of impact is described in Section 4.3.3 for each component and summarized in Tables S- 1 and S-2. Each of the projects will undergo second tier analysis at which time potential impacts to critical habitat will be evaluated. The Draft Program EIR does not identify significant unmitigable impacts to biological resources at this first-tier level of CEQA analysis. Nesting birds, including potential noise effects issues and raptor breeding issues, are addressed in Section 4.3.3 and in Tables S- 1 and S-2 of the Program EIR. For instance, refer to Component 22 in Table S-1 which recommends a future noise assessment and appropriate mitigation for potential noise impacts to nesting sensitive birds. Also, the first bullet in Section 4.3.4 includes a mitigation measure to design future projects with seasonal restrictions in mind in order to reduce potential impacts to birds and nests. The recommended change to Table 2-5 has been incorporated into the Program EIR regarding the size of the buffer area for nesting raptors. Table 2-5 of the Program EIR has been changed to reflect this comment regarding the use of temporary fencing where construction is proposed within 100 feet of proposed biological open space. ~- October 2003 I I I I I I I I. 14 I I I I I 1 I 1 1 1 1 1 1 1 1 1 1 1 1 1 RESPONSES TO COMMENTS + ClN OF CARLSBAD WATER AND SEWER MASTER PLAN UPDATES PROGRAM EIR COMMeNT8 P. 07 ;EP-23-7003 TUE 10:46 AN CITY OF C(IRLSB(ID uu win FRX NO. 760 602 a559 IC- "I 19/22/2893 13: 48 8584674299 - 2.

The City's draft HMP will be adhered to in identifying the proper mitigation ratios during the second-tier analysis. A full project description is detailed in Chapter 2 of the Draft Program EIR, including the purpose and need for the project. Detailed project descriptions for each of the 84 project components would be described during future second-tier CEQA review, including information such as the location and use of any access roads and staging areas. A list of the most commonly occurring flora and fauna in the project study area is included in Section 4.3.1 of the Program ElR. The list would be modified as necessary during second-tier CEQA review. The EIR analysis included a search using the California Natural Diversity Database and MHCP data, and standard accepted practice for biological resource analysis in CEQA documentation was employed. Recommended future surveys are identified in Tables S-1 and S-2 of the Program EIR. Future second-tier review will also address these issues in greater detail. Specific impact acreages to wetlands, coastal sage scrub, and other habitats for each of the project components identified in the Water and Sewer Master Plan Updates is beyond the scope of the Program EIR. However, as noted in the document, additional analysis at the time of second-tier CEQA review would fully identify these specific impacts since at that time, project-level details for each component would become available. The regional setting is described in Chapter 3 of the Program EIR, and the existing biological setting is detailed in Section 4.3.1 including identification of rare and unique species in the project area.

As noted in response to comment D-7, additional analysis at the time of second-tier CEQA review would fully identify these specific impacts since project- level details for each component would become available at that time. Refer also to Section 4.3.1 for information on potentially occurring species in the project area, including information on their distribution and local status. D-10 The Draft Program EIR discusses brush management activities in Table 2-5. In determining potential impacts to biological resources, the Draft Program EIR included brush management activities in the determination of project impacts, as applicable. Also, additional review of any brush management impacts to biological resources will be conducted as part of future project-level analyses. D-11 The Draft Program EIR addresses all projects proposed under the Water and Sewer Master Plan Updates, including closure or relocation of pipelines or related facilities, and those located in or near sensitive habitats. The full list of projects is shown in Chapter 2. D-12 Indirect impacts to biological resources were considered in the impact analysis in Section 4.3.3 of the Program EIR and would also be considered during project- level review of future projects identified in the Master Plan Updates. This includes indirect impacts as a result of lighting, noise, human activity, wildlife corridors, exotic species, and drainage. D-13 Potential conflicts resulting from wildlife-human interactions would be fully addressed at the project level of CEQA review for the projects identified in the Master Plan Updates. D-14 Cumulative effects to biological resources are described in Section 5.2 of the Program EIR. As described in that section, cumulative impacts would be significant due to losses in habitat value. Mitigation would be accomplished through the assessment and mitigation of project-specific impacts as individual components of the Master Plans are implemented and, when the MHCP is implemented, through a regional conservation plan in cooperation with CDFG USFWS, and other cities in the area. The City of CarIsbad draft HMP will address cumulative biological effects as part of the MHCP process; however, until that document is implemented, cumulative impacts would be significant .. would -ted.

Additional mitigation measures may also be prescribed as part of project-level CEQA review. D-17 Comment noted that mitigation measures should first emphasize avoidance. Mitigation measures emphasizing avoidance are listed first in Section 4.3.4 of the Program EIR. The Program EIR does not identify relocation, salvage, or transplantation as mitigation for impacts on sensitive or listed species. D-18 Comment noted that the objective of mitigation measures should be to offset the project-induced qualitative and quantitative losses of wildlife habitat values. As described in response to comment D-16, mitigation measures for project- related biological resource impacts (including effects to sensitive plants, animals, and habitats) are described at the program level of analysis in Section 4.3.4 of the Program EIR, and project-level impact analyses and mitigation measures would be identified as necessary as part of future project-level CEQA review. The details on restoration plans cited in this comment are noted and will be taken into consideration for applicable mitigation measures at the project level of analysis. 1 17 October 2003 I COMMENT8 Pa IO FhX NO, 760 602 8559 ,.,__ __ vu -4" -I t-1 '-23-2003 TUE 10:47 AH 22/2003 17: 40 95846742YY CITY OF CARLSBAD 6, 'Ihc Wildlife Agcnclei havc msponiiblllty for the conmalion of wctlmc! and riparlen haMtPu.

This includes indirect impacts as a result of hydrologic regime effects and using appropriate means to convey runoff without damaging biological resources. Also refer to the Hydrology and Water Quality analysis in Section 4.7.3 of the Program EIR. D-20 The City of Vista Sanitation District has an easement through CDFG-owned property in the Buena Vista Lagoon ecological reserve. The easement accommodates an existing 24-inch force main that runs from the Jefferson Street Pump Station to the Encina Wastewater Treatment Plant (WTP). The City of Carlsbad plans to construct a parallel 24-inch line to this pipeline in the future, identified as Sewer component 30 in the Program EIR. The impacts of this project are described in Section 4.3.4. The same force main extending from the Jefferson Street Pump Station crosses Agua Hedionda Lagoon en route to the Encina WTP. This project component is identified as Sewer component 3 1 in the Program EIR. Refer to Section 4.3.4 for the impact assessment for this project component. In addition, Water component 22 would be located adjacent to the Batiquitos Lagoon; however, this component would be located entirely within the right- of-way of Carlsbad Boulevard and would not affect the CDFG lands.

Impacts to wetlands were addressed at the program level of analysis in Section 4.3.3 of the Program EIR and would be duly considered during project-level CEQA review for applicable project components. Mitigation measures, particularly the "no net loss" policy, will be explored during second-tier environmental analyses. It is acknowledged that jurisdictional delineations of water bodies may be required of the project components, which would occur during project-level review. The delineations would follow the applicable USFWS, CDFG, andor ACOE protocol. The City acknowledges that some components of the proposed project may require a Section 1603 Streambed Alteration Agreement (SAA), and that CDFG may consider the City's Program EIR to satisfy the SANS CEQA requirements. The Final Program EIR fully identifies the potential impacts on the stream and riparian resources and provides adequate mitigation, monitoring, and reporting commitments at the program level of analysis. Additional mitigation, monitoring, and reporting commitments will likely be specified during project-level CEQA documentation. The lead agency will endeavor to assure that environmental documents for subsequent projects address CDFG's concerns.
