Existing Conditions & Project Description Two aging water and sewer pipelines run underneath the north and southbound lanes of Carlsbad Boulevard, varying between 6 to 12 inches in diameter. The proposed project would replace the two existing pipelines with a single pipeline spanning 5,000 linear feet. The project would bring the water and sewer main systems to current design Sept 20, 2023 Item #2 Page 1 of 256 standards. The project is entirely within the public right-of- way. Table “A” below includes the General Plan designations, zoning, and current land uses of the subject site and surrounding properties.

CMWD proposes the following: 1) water main replacement and abandonment or removal, and 2) replacement or rehabilitation of sewer mains and maintenance holes. 1. Water Main Replacement and Abandonment The project will upgrade approximately 7,500 linear feet of current pipelines with a new singular 12-inch, 5,000 linear foot pipeline and will abandon in place 2,500 linear feet of the existing pipeline within the Carlsbad Boulevard and Cannon Road right-of-way. The existing eight-inch water mains will be either filled Sept 20, 2023 Item #2 Page 2 of 256 with slurry for abandonment or completely removed. The water main will encompass and integrate all related components into the current water systems. 2. Replace or Rehabilitate Sewer Mains and Maintenance Holes The project also encompasses the rehabilitation of six-inch sewer mains and maintenance holes through a combination of trenchless repair and open trench replacements, covering around 1,500 linear feet in total. Among these, approximately 800 linear feet will undergo rehabilitation, while the remaining 700 linear feet will be replaced with an upgraded pipeline size, transitioning from six inches to eight inches in diameter. The project is part of the city’s Capital Improvements Program (CIP) to maintain, rehabilitate, improve, or replace infrastructure as identified by condition assessments, engineering studies, or feedback from maintenance and operations teams. Construction of the project would improve system reliability and accessibility. The project would take approximately eight to ten months to complete and would not occur during summer. Project plans are attached to the staff report (Exhibit 5). The improvements between Tierra del Oro and Cannon Road, which account for approximately 300 feet, were not previously analyzed in the Program Environmental Impact Report for the Sewer and Water Master Plans. Therefore, this project also requires the approval of an addendum to the PEIR. This is discussed in detail in the environmental section below. Public Outreach & Comment Public notice of the proposed project was mailed on Sept. 7, 2023, to property owners within 600 feet and occupants within 100 feet of the project sites. A total of 248 owners and 56 tenants were notified. No comments were received during this public outreach effort. Project Analysis General Plan Consistency The City of Carlsbad General Plan includes several goals and policies that guide development and land use within the city. A discussion of how the project is consistent with the applicable General Plan policies is summarized in Exhibit 2. Municipal Code Consistency The City of Carlsbad Municipal Code, most notably Title 21 Zoning Code, includes requirements and provisions that guide development and land use within the city, consistent with the General Plan. Specific compliance with these relevant requirements is described in Exhibit 3. Local Coastal Program Consistency The project site is in the Coastal Zone within the Mello II and Agua Hedionda Lagoon segments of the Local Coastal Program (LCP). It requires approval of a coastal development permit from the city and the California Coastal Commission (Coastal Commission). The project complies with the LCP, including all goals and policies of the General Plan and all zoning code standards, as referenced above. A section of the project falls within the Agua Hedionda Lagoon segment, an area with deferred certification as outlined in the LCP. In the deferred certification areas of the LCP, the Coastal Commission retains permit authority. For this project, the Coastal Commission will issue permits for the improvements that extend along Carlsbad Boulevard from Tierra Del Sol to Cannon Road and along Cannon Road from Carlsbad Boulevard to Avenida Encinas. The Coastal Commission holds appeal jurisdiction for the improvements starting from the intersection of Cannon Road and Carlsbad Boulevard, extending 210 feet south to Shore Drive, and additionally spans from the southernmost intersection of Carlsbad Boulevard and Shore Drive to the project’s southern boundary ending at Manzano Drive. A map that shows the jurisdictional boundaries has been created as Exhibit 5. Sept 20, 2023 Item #2 Page 3 of 256 Discretionary Actions & Findings The proposed project requires approval of a Coastal Development Permit, which is discussed below. Coastal Development Permit (CDP 2022-0056) Approval of a Coastal Development Permit (CDP) is required to ensure that the project complies with the Local Coastal Program, including all goals and policies of the General Plan and all zoning code standards, as referenced above. Staff finds that the required findings for this application can be met (Exhibit 3). Environmental Review In accordance with the city’s CEQA procedures and CEQA Guidelines section 15080 through 15097, a Program Environmental Impact Report (PEIR), State Clearinghouse No. 2012021006, and City Planning Case No. EIR12-01 was certified as complete on Nov. 13, 2012, by the City Council for the City of Carlsbad Sewer Master Plan, Carlsbad Municipal Water Master Plans, and Recycled Water Master Plan. The Master Plans were updated in 2019 and 2022, and an addendum to the PEIR was prepared to address the changes. Subsequently, two addendums have been approved for this PEIR over the past several years. In 2019, the Sewer and Water Master Plans were updated with an improved analysis of demand forecasts and hydraulic modeling and required an addendum to the EIR12-01. The addendum and resolution are available here: 2019-09-17, City Council Resolution No. 2019-183 (carlsbad.gov). In 2022, CMWD proposed modifications to two motorized valves, requiring a second addendum to the PEIR to properly analyze the changes and required a second addendum to EIR12-01. This addendum is attached to this staff report as Exhibit 6. Pursuant to CEQA Guidelines, when taking subsequent discretionary actions in furtherance of a project for which a PEIR has been certified, the Lead Agency is required to review any changed circumstances or new information to determine whether any of the circumstances under Public Resources Code section 21166 and CEQA Guidelines section 15162 through 15164 require additional environmental review. City staff conducted this review and concluded that the PEIR thoroughly analyzed and mitigated, where feasible, all potentially significant environmental impacts, if any, that would result from the revised project, and therefore, no subsequent PEIR or subsequent mitigated negative declaration is required. On that basis, staff has prepared a third addendum for the changes, pursuant to CEQA Guidelines section 15164. The addendum is provided as Attachment A to the draft resolution (Exhibit 1). The addendum is appropriate pursuant to CEQA Guidelines section 15164 because only minor changes and additions to the Final EIR are necessary to address the project changes, and no circumstances exist calling for the preparation of a subsequent or supplemental PEIR pursuant to CEQA Guidelines sections 15162 and 15163. The proposed addendum concluded that there are no substantial changes to the circumstances under which the proposed project is undertaken that would require major revisions to the Final PEIR. There is no new information of substantial importance that was not known or could not have been known at the time the Final PEIR was certified that shows the proposed project would have significant effects not discussed previously: a substantial increase in severity of a previously identified significant impact; mitigation measures or alternatives previously found infeasible that would now be feasible and would substantially reduce one or more significant effects; or mitigation measures or alternatives which are considerably different from those analyzed in the Final PEIR which would substantially reduce one or more significant effects on the environment. The project would not result in new or more severe impacts beyond those addressed in the Final PEIR and would not meet any other standards requiring further environmental review under State CEQA Guidelines Sections 15162 and 15163. No further analysis or environmental documentation is required. Sept 20, 2023 Item #2 Page 4 of 256 Conclusion Considering the information above and in the referenced Exhibits, staff has found that the project is consistent with all applicable policies of the General Plan and Local Coastal Program, provisions of the Municipal Code, and Local Facility Management Zone. In addition, there are no new environmental impacts associated with the project. The project is conditioned to ensure compatibility with the surrounding properties and maintain the community's public health, safety, and welfare. The project must comply with all applicable California Building Standards Codes and engineering standards through the standard building permit and civil improvement plan checking process. Staff recommends that the Planning Commission adopt the resolutions and approve the project described in this staff report.

NOW, THEREFORE, BE IT HEREBY RESOLVED by the Planning Commission of the City of Carlsbad, as follows: a)The Planning Commission has considered the full record before it, which includes the Record of Proceedings. Furthermore, the recitals set forth above are found to be true, correct, and material to this resolution; and incorporated herein by reference. b)Compliance with CEQA. State CEQA Guidelines section 15164 requires lead agencies to prepare an Addendum to a previously certified PEIR if some changes or additions to the project are necessary, but none of the conditions requiring preparation of a subsequent PEIR are present. The Planning Commission has reviewed and considered the PEIR and Addendum and finds that those documents taken together contain a complete and accurate reporting of all of the environmental impacts associated with the revised project. The Planning Commission further finds that the Addendum and Sept 20, 2023 Item #2 Page 8 of 256 administrative record have been completed in compliance with CEQA and CEQA Guidelines, and that the findings related to the PEIR and Addendum, taken together, reflect the Planning Commission's independent judgment. Based upon the evidence submitted and as demonstrated by the analysis included in the Addendum, which is attached hereto as Attachment "1" none of the conditions described in CEQA Guidelines sections 15162 through 15164 calling for the preparation of a subsequent or supplemental PEIR or negative declaration have occurred; specifically: 1.The proposed modifications to the project do not create substantial changes that would require major revisions to the PEIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; and 2.The proposed modifications to the project do not create substantial changes with respect to the circumstances under which the project is undertaken that will require major revisions of the previous PEIR due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; and 3.There is no new information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the PEIR was certified as complete and adopted, that shows any of the following: Sept 20, 2023 Item #2 Page 9 of 256 i. The modifications will have one or more significant effects not discussed in the certified F>EIR; ii.Significant effects previously examined will be substantially more severe than shown in the certified PEIR; iii.Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the Applicant declines to adopt the mitigation measure or alternative; or iv.Mitigation measures or alternatives that are considerably different from those analyzed in the certified PEIR would substantially reduce one or more significant effects on the environment, but the Applicant declines to adopt the mitigation measure or alterative; and v.The evaluation of the proposed modifications to the project, certified PEIR, and Third Addendum reflects the Planning Commission's independent judgment and analysis based on review of the entirety of the administrative record, which record provides the information upon which this resolution is based. c)Pursuant to the above findings, the Planning Commission determines that the PEIR, together with the Addendum, satisfy all the requirements of CEQA and is Sept 20, 2023 Item #2 Page 10 of 256 adequate to serve as the required environmental documentation for the project and, therefore approves and adopts the Addendum for the project. d)The custodian of the documents and other materials which constitute the record of proceedings upon which this decision is based is the Office of the City Clerk of the City of Carlsbad, 1200 Village Dr., Carlsbad, CA 92008. BE IT FURTHER RESOLVED that the Planning Commission directs the City Planner to file the notice of determination required by Public Resources Code section 21152(a) within five days after project approval. NOTICE TO APPLICANT An appeal of this decision to the City Council must be filed with the City Clerk at 1200 Carlsbad Village Drive, Carlsbad, California, 92008, within ten (10) calendar days of the date of the Planning Commission's decision.

Yes B.Coastal Development Permit Procedures (CMC Chapter 21.201) The project is in the Coastal Zone within the Mello II and Agua Hedionda Lagoon segments of the Local Coastal Program (LCP). It requires the approval of a coastal development permit from the city and the California Coastal Commission (Coastal Commission). A section of the project falls within the Agua Hedionda Lagoon, an area with deferred certification as outlined in the LCP. In the deferred certification areas of the LCP, the Coastal Commission retains permit authority. For this project, the Coastal Commission will issue Sept 20, 2023 Item #2 Page 102 of 256 PROJECT ANALYSIS (GENERAL PLAN, MUNICIPAL CODE, AND OTHER REGULATIONS) permits for the improvements that extend along Carlsbad Boulevard from Tierra Del Sol to Cannon Road and along Cannon Road from Carlsbad Boulevard to Avenida Encinas. The Coastal Commission holds appeal jurisdiction for the improvements starting from the intersection of Cannon Road and Carlsbad Boulevard, extending 210 feet south to Shore Drive, and additionally spans from the southernmost corner of Carlsbad Boulevard and Shore Drive to the project’s southern boundary ending at Manzano Drive, pursuant to CMC Chapter 21.201. The city must find that the project complies with the certified LCP to approve a coastal development permit. LCP provisions applicable to the project include the Mello II segment of the LCP Land Use Plan, the Zoning Ordinance, including the Coastal Resource Protection Overlay Zone (Chapter 21.203) and the Coastal Shoreline Development Overlay Zone (Chapter 21.204), and the Habitat Management Plan. 1. Mello II Segment of the Certified Local Program and all applicable policies This project is entirely within the public right-of-way and has no land use designation. The project is consistent with the LCP in terms of providing coastal access and protecting coastal resources and does not conflict with any of the policies included in the LCP. The project would be constructed within a public roadway, and public access to the beach would be maintained at all times during construction by implementing a traffic control plan. The traffic control plan will be prepared and implemented in accordance with the California Department of Transportation Manual of Traffic Controls for Construction and Maintenance Work Zones. Major construction activities will avoid the peak tourist season between Memorial Day and Labor Day. Access to the beach during the construction of the project will not impact visitors or residents. As discussed in Section “A” above, the project is consistent with the General Plan. Therefore, the project is compatible with the Mello II Segment of the LCP. The Mello II Segment policies also emphasize hazard identification within shoreline areas and the preservation of shoreline access and scenic resources. 2. Coastal Resource Protection Overlay Zone (CMC Chapter 21.203) The project will adhere to the city’s Master Drainage Plan, Grading Ordinance, Storm Water Ordinance, BMP Design Manual, and Jurisdictional Runoff Management Program (JRMP) to avoid increased urban run-off, pollutants, and soil erosion. The subject property is within the public right-of-way, and public utility and access easements do not include steep slopes (equal to or greater than 25 percent gradient) nor native vegetation. The site is not located within an area prone to landslides or susceptible to accelerated erosion, liquefaction, or flooding. 3. Coastal Shoreline Development Overlay Zone (CMC Chapter 21.204) The Coastal Shoreline Development Overlay Zone (CMC Chapter 21.204) applies to all areas within the Mello II Segment of the Carlsbad LCP located between the sea and the first public Sept 20, 2023 Item #2 Page 103 of 256 PROJECT ANALYSIS (GENERAL PLAN, MUNICIPAL CODE, AND OTHER REGULATIONS) road parallel to the sea. The subject site is located on the right-of-way along Carlsbad Boulevard between Tierra Del Oro and Manzano Drive. The overlay zone specifies requirements for public access to the beach, and the project is consistent with these requirements. The project would be constructed within a public roadway, and public access to the beach would be maintained at all times during construction by implementing a traffic control plan. The traffic control plan will be prepared and implemented in accordance with the California Department of Transportation Manual of Traffic Controls for Construction and Maintenance Work Zones. Major construction activities will avoid the peak tourist season between Memorial Day and Labor Day. The project will adhere to the city’s Master Drainage Plan, Grading Ordinance, Storm Water Ordinance, BMP Design Manual, and Jurisdictional Runoff Management Program (JRMP) to avoid increased urban run-off, pollutants, and soil erosion. Therefore, the project complies with the requirements of the Coastal Shoreline Development Overlay Zone. C. Growth Management Ordinance and Local Facilities Management Zone 3 The project is located within Local Facilities Management Zone 3 in the city's southwest quadrant. The project is consistent with the Preservation of Resources and Outdoor Recreation policies in the Growth Management Ordinance.

The current Sewer, Water, and Recycled Water Master Plans (Master Plans), adopted in November 2012, were evaluated in a program environmental impact report (PEIR) prepared and certified by the city (State Clearinghouse [SCH] No. 2012021006). The Master Plans were updated in 2019 and an Addendum to the PEIR (2019 Addendum) was prepared to address the changes from the 2012 PEIR. The proposed Project would update improvements included as part of the Water Master Plan. The city and CMWD are responsible for the maintenance, operations, and management of sanitary sewer collection systems, and water and recycled water distribution systems in their respective service areas. The Master Plans represent comprehensive programs for the phased and orderly development of sewer, water, and recycled water infrastructure in response to future demands within the respective service areas. They consist of projects incorporated into a Capital Improvement Program (CIP) to construct new facilities and modify or expand existing facilities. The 2012 PEIR and 2019 Addendum analyzed the potential physical impacts to the environment that would result from those improvements. This addendum is prepared in accordance with the California Environmental Quality Act (CEQA) (Public Resources Code §21000, et. seq.) and the CEQA Guidelines, as amended (California Administrative Code, Title 14, §15000, et. seq.). 1.1 Applicability and Use of Addendum The 2012 PEIR contemplated the idea of “tiering” from the document to allow for subsequent environmental documents to focus on those issues specific to the later project which were not addressed in the PEIR. In particular, the environmental documents for a later project would focus on the environmental effects which are capable of being integrated or were not analyzed as significant effects on the environment in the PEIR. In effect, tiering enables agencies to analyze environmental issues that are ready for decision at each stage, and to exclude issues that have already been decided or that are not ready for decision. The city and CMWD’s intent through preparation of this addendum is to demonstrate whether the previously adopted CEQA documents (2012 PEIR and 2019 Addendum), including mitigation measures, are still both adequate and valid for the proposed Project. Pursuant to Public Resources Code Section 21166 and the CEQA Guidelines, Sections 15162 through 15164, the city as the CEQA lead agency is required to conduct a fact-based evaluation of proposed changes to the Master Plan to determine whether supplemental environmental documentation is required. CEQA Guidelines, Section 15162(a), states that when an Environmental Impact Report (EIR) is certified for a project, no subsequent EIR shall be prepared for that project unless the lead agency determines that one of the conditions described in Section 15162(a) has occurred. Section 15164(a) provides that an addendum is appropriate if none of the conditions described in Section 15162(a) have occurred. Based on the analysis set forth in this addendum, the city and CMWD have concluded that the proposed Project does not trigger any of these circumstances, and that an addendum is the appropriate form of documentation to comply with CEQA. Sept 20, 2023 Item #2 Page 113 of 256 1.2 Format of This Addendum The PEIR and 2019 Addendum serve as the environmental compliance documents for the proposed Project, and this addendum provides additional clarification and information about the specific updates to the city’s Water Master Plan. This addendum should be read together with the full text of the previously certified PEIR (2012a) and 2019 Addendum. Mitigation measures and project design features from the PEIR and 2019 Addendum, as provided in the Project-specific Mitigation Monitoring and Reporting Program (MMRP) found in Chapter 5 of this addendum, are incorporated by reference into this addendum. In addition, the addendum incorporates by reference the city’s General Plan Update, supporting PEIR (2015a), and Climate Action Plan (2015b). This addendum relies on the use of an Environmental Checklist Form (Checklist), as suggested in Section 15063(d)(3) of the CEQA Guidelines, as amended. 1.3 Summary of Findings Based upon the Checklist prepared for the proposed Project and supporting responses (Section 4), implementation of the proposed Project would not result in substantial changes requiring major revisions to the PEIR. Further, the proposed Project would not result in any environmental impacts that have not already been addressed in the PEIR, and no new mitigation measures are required. Since only minor additions and clarifications are required to the PEIR, and none of the conditions described in Public Resources Code Section 21166 or CEQA Guideline Section 15162 have occurred, the city and CMWD finds that the preparation of an addendum to the PEIR is appropriate and consistent with Public Resources Code Section 21166 and CEQA Guidelines Sections 15162-15164. 1.4 Lead Agency and Discretionary Approvals This addendum and the PEIR are intended to serve as the environmental documentation for the proposed Project. The City of Carlsbad is the lead agency under CEQA and maintains authority to approve the addendum. 2.0 Description of the Proposed Project CMWD is currently proposing improvements to previously identified water CIP projects, the El Fuerte and Maerkle Motorized Valves Project (collectively referred to as the Project or Projects). 2.1 Project Locations The proposed Project improvements are generally located in the northern part of San Diego County within the City of Carlsbad (Figure 1, Regional Location). The El Fuerte Motorized Valve site is located within El Fuerte Street and a 300 square foot easement (Assessor’s Parcel Number [APN] 222-600-01). The valve location is north of the intersection with Rancho Pancho and the corrosion test stations are located between Rancho Pancho and Alga Road, as show in Figure 2, Project Locations. The easement area has a General Plan land use designation of Community Facilities and is zoned as Planning Community – Rancho Carrillo Master Plan – Village T (Community Facility).

The site is located within parcel (APN 760-166-86-00) that has a land use designation and zoning of Open Space. 2.2 Project Description I. El Fuerte The El Fuerte Motorized Valve Project involves the installation of a new valve vault, 24-inch and 30-inch diameter steel piping, a motorized valve and cathodic protection improvements on the existing 30-inch steel water transmission main in El Fuerte Street. The new motorized valve would replace an existing valve located on the boundary of two water pressure zones at the intersection with Rancho Pancho and is used to ensure adequate water supply and water quality in the system. The new valve would be installed in a new underground vault and easement, outside of the road under portions of the sidewalk and landscape, to facilitate access and to improve worker safety. Corrosion test stations would be installed at five locations along the pipeline in El Fuerte Street. The work would involve trenching excavation in asphalt concrete pavement, concrete sidewalk, and ornamental landscape to remove and replace portions of the 30-inch piping and to install an approximately 8-foot-deep valve vault. Installation of the corrosion test stations would involve minor trenching in the roadway to install wiring and at-grade covers behind the sidewalk for test station access. The El Fuerte Motorized Valve Project was included as CIP Project Number W-13 in the 2019 Addendum as well as the PEIR as Project 21. Cathodic protection projects, such as the proposed corrosion test stations, were included in the 2019 Addendum as project 50071 under the Asset Management Program. II. Maerkle The Maerkle Motorized Valve Project is located near the Maerkle Reservoir and involves the replacement of two existing isolation valves and piping with new motorized valves and piping, which would automate water system operations. The existing 24-inch and 42-inch valves divert water into the 10-million-gallon tank and the 200-million-gallon reservoir. The new valves would be installed in a new underground vault at the base of the slope to make it easier to access the valves and to improve worker safety. The work would involve trenching excavation to remove and replace the 24-inch and 42-inch valves and piping, along with the installation of an approximately 12-foot-deep new vault. Approximately 2,400 square feet of ground could potentially be affected, though the ground has been previously disturbed from the installation of large diameter pipelines and construction of the existing 10-million- gallon tank, and some of which is a walking path to the existing valves for operation. Facility improvements at the Maerkle Reservoir are included as CIP project W-9 (50091) in the 2019 Addendum, as well as the PEIR as project R7. However, the improvements were described in the PEIR as replacing joint sealing in the 10-million-gallon tank and adding security lights and cameras along the access road, gates, and site. Excavation and/or ground disturbance was not anticipated at the time. Sept 20, 2023 Item #2 Page 117 of 256 2.3 Construction Methods Construction of the Projects is scheduled to begin between early 2023 and early 2024. The El Fuerte and Maerkle Motorized Valve improvements are planned to be constructed under a single contract and would be constructed simultaneously or in close succession. Construction would involve open trench methods, utilizing typical construction equipment such as dozers, rollers, dewatering pumps, backhoes, loaders, delivery, and haul trucks. 2.4 Regulatory Compliance As described in PEIR Chapter 2.6.1, Regulatory Compliance, construction and operation of the CIP projects would be conducted in compliance with all applicable federal, state, and local laws and regulations. Updates to the original description are provided based on changes in existing conditions described in the PEIR. Since the certification of the PEIR, the National Pollutant Discharge Elimination System (NPDES) Permit and Waste Discharge Requirements for Discharges from the Municipal Separate Storm Sewer Systems Draining the Watersheds within the San Diego Region (Order No. R9-2013-0001, NPDES No. CAS0109266) were amended. The updated permit requires projects not falling within the triggering coverage thresholds of the General Permit to comply with the implementing ordinances of the county and cities bound by the Municipal Separate Storm Sewer Systems permit in which the improvements are located. 2.5 Project Design Features As part of the PEIR and 2019 Addendum, CMWD incorporates several project design features and construction measures into the Project designs in an effort to reduce the potential for adverse environmental effects. These features are incorporated by reference from Chapter 2.6.2, Project Design Features, of the PEIR. The project design features are also provided in the MMRP. 3.0 Environmental Setting This section incorporates by reference Chapter 3, Environmental Setting, from the PEIR and the 2019 Addendum, as applicable. This section focuses on the Water Service and Master Plan, as the proposed Project improvements are related to potable water service. 3.1 Existing Water Service and Master Plan (including 2019 Addendum) Originally, the Water Master Plan was approved in 1990 with recommendations and revisions prepared in 1997 and adopted with the 2003 update. The 2003 Water Master Plan Update evaluated the CMWD water distribution system and its ability to meet project demands. Since the Master Plan Update in 1997, a substantial number of residential, commercial, and industrial developments had been constructed and future development had been identified in the 2001 Growth Management Database. The 2003 document presented an update of CMWD’s Water Master Plan for the planning period Sept 20, 2023 Item #2 Page 118 of 256 between 2001 and buildout of the CMWD’s service area, which was anticipated to occur by 2020. CMWD reviewed all infrastructures within the service area to identify necessary improvements to existing facilities, capacity improvements, and expansion needs. An update to the Water Master Plan was prepared in 2012 and analyzed in the PEIR. The update included a capacity evaluation to meet future demands and recommended CIP projects for continued reliable water service through buildout in accordance with the Carlsbad Growth Management Plan. Considering the significant projected buildout, potable water demand was anticipated to increase 8 percent from 19.1 million gallon per day (mgd) (21,392 acre feet per year [afy]) in 2007 to 20.8 mgd (23,296 afy) in 2035. Between 2035 and 2050, water demand was projected to increase three percent to 21.4 mgd (23,968 afy). The Water Master Plan was again updated in 2019 based on more recent demand forecasts and hydraulic modeling. A median water demand forecast of 20,700 afy or 18.5 mgd at buildout (2040) was used as the basis for the 2109 Water Master Plan Update. This projection was lower than the 2035 forecast used in the 2012 Water Master Plan (CMWD 2012b). Water service is provided by the CMWD, encompassing approximately 83 percent of Carlsbad. The remaining areas are serviced by the Olivenhain Municipal Water District in the southern portion and Vallecitos Water District in the eastern portion of the city. The CMWD receives 100 percent of its potable water supply from the San Diego County Water Authority, delivering water through 450 miles of pipeline, 71 pressure regulating stations, five pump stations, eight storage tanks, and one earthen dam reservoir. The total operational storage for CMWD is 244 million gallons, which includes the 195-million- gallon Maerkle Reservoir. 3.2 Local and Regional Planning Context This section incorporates by reference Chapter 3.3, Local and Regional Planning Context, from the 2012 PEIR and 2019 Addendum. I. City of Carlsbad General Plan (2015a) The Carlsbad General Plan contains nine elements, with each element containing maps and figures, policy statements, over-arching goals, specific objectives, implementing programs, and in some instances, development standards. The Land Use and Community Design Element emphasizes the Growth Management Plan requiring that adequate public facilities are provided concurrent with new growth, specifically identifying performance standards for 11 public facilities: city administration, library, wastewater treatment, parks, drainage, circulation, fire, open space, schools, sewer collection, and water distribution. The Sustainability Element encourages conservation and reduced reliance on imported water. II. City of Carlsbad CAP The City of Carlsbad has developed a Climate Action Plan (CAP) to help the city meet state goals for reducing greenhouse gases and the community’s goal of promoting a sustainable environment. The CAP serves as a long-range strategy to reduce emissions of greenhouse gases, which include carbon dioxide, methane, nitrous oxide, and water vapor. The CAP sets a baseline for past and current emissions, forecasts future emissions, and establishes targets to reduce the intensity of greenhouse gas (GHG) Sept 20, 2023 Item #2 Page 119 of 256 emissions from water utilities (including water supply, wastewater, and recycled water) conveyance, treatment, and distribution by 8 percent by 2035. 4.0 Environmental Analysis Checklist 4.1 Environmental Analysis Checklist Summary The following Environmental Analysis Checklist (Checklist) (Table 4-1) was developed for projects with previously certified/approved environmental documents. This Checklist takes into consideration the preparation of an environmental document prepared at an earlier stage of a project (e.g., the PEIR for the Sewer, Water and Recycled Water Master Plans, certified in 2012, and the 2019 Addendum for the Master Plans updates), evaluates the adequacy of the earlier document in assessing potential environmental impacts resulting from the Projects, and is consistent with Section 21166 of the Public Resources Code and Section 15162 of the CEQA Guidelines. The results of this evaluation are summarized below with the detailed analysis provided in subsequent sections, including updated impact determinations.1 Table 4-1 ENVIRONMENTAL ANALYSIS CHECKLIST SUMMARY Environmental Issue Area Was Impact Analyzed in Prior Environmental Document(s)?

Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Except as provided in Public Resources Code Section 21099, would the project: a) Have a substantial adverse effect on a scenic vista? Yes No No No b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? Yes No No No Sept 20, 2023 Item #2 Page 121 of 256 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? Yes No No No d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Yes No No No a) Have a substantial adverse effect on a scenic vista? The potential impacts of the proposed Projects on scenic vistas were analyzed in the PEIR (Section 4.1) and 2019 Addendum. Impacts to scenic vistas could occur from construction activities, including disturbance of ground cover, grading, excavation, trenching, material stockpiles, and the presence of construction equipment. The majority of the proposed Project improvements would be contained to the public road right-of-way and located underground or co-located with existing storage facilities, resulting in minimal impacts to scenic vistas. The proposed Project improvements would be contained in generally urbanized landscapes and public rights-of-way and would not have a substantial adverse effect on scenic vistas. No substantial new information has been presented that shows the Project improvements would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? The potential impacts of the proposed Projects on scenic highways were analyzed in the PEIR (Section 4.1) and 2019 Addendum. There are no designated State Scenic highways in Carlsbad; therefore, no impacts related to scenic highways would occur (California Department of Transportation 2019). However, Interstate 5 is an eligible State Scenic highway and Carlsbad has its own scenic roadways program. Additionally, local scenic roadways are recognized by Carlsbad’s General Plan (2015a) including El Camino Real, Carlsbad Boulevard, Palomar Airport Road, La Costa Avenue, Melrose Drive, College Boulevard, Cannon Road, Carlsbad Village Drive, Faraday Avenue, Interstate 5, La Costa Avenue, Olivenhain Road/Rancho Santa Fe Road, and Poinsettia Lane/Carrillo Way, Adams Street/Park Sept 20, 2023 Item #2 Page 122 of 256 Drive, Batiquitos Drive, and Jefferson Street (the portion adjacent to the Buena Vista Lagoon). The Atchison, Topeka, and Santa Fe Railroad line is also considered a scenic corridor. The Project locations would not be visible from a scenic corridor. As incorporated in the PEIR, the Projects would be required to follow project design features, including the following: • Demolition debris will be removed in a timely manner for off-site disposal; • Tree and vegetation removal will be limited to those depicted on construction drawings; and • Disturbed areas will be restored following construction consistent with original site conditions and surrounding vegetation. If removed vegetation included invasive plant species, the restored area shall be revegetated with a mix of native, non-invasive plants that are compatible with the surrounding setting. Implementation of these project design features and compliance with federal, state, and local requirements and regulations would limit the visibility of construction activities. The proposed Project improvements would be contained in urbanized landscapes and beneath public rights-of-way and would not have a substantial adverse effect on scenic highways given they would not be visible from these corridors. No substantial new information has been presented that shows the Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? The potential impacts of the proposed Projects on the existing visual character of the city landscape were analyzed in the PEIR (Section 4.1) and 2019 Addendum. Impacts to scenic vistas could occur from construction activities, including disturbance of ground cover, grading, excavation, trenching, material stockpiles, and the presence of construction equipment. Project improvements are mostly below-ground valve installations, with the exception of access points. Following construction, there would be no substantial change to scenic quality from existing conditions. The proposed Projects would not have a substantial adverse effect on the existing visual character of the city. No substantial new information has been presented that shows the Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. d) Create a new source of substantial light or glare that would adversely affect day or nighttime views in the area? The potential glare and nighttime lighting impacts of the proposed Projects were analyzed in the PEIR (Section 4.1) and 2019 Addendum. The proposed Projects involve valve replacements and corrosion test station installation, which do not include any new lighting sources. The proposed Projects would not Sept 20, 2023 Item #2 Page 123 of 256 have a substantial adverse effect on existing sources of daytime glare or nighttime lighting. No substantial new information has been presented that shows the proposed Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. II. Agriculture and Forestry Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? Yes No No No b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? Yes No No No c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? Yes No No No d) Result in the loss of forest land or conversion of forest land to non-forest use? Yes No No No e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non- forest use? Yes No No No Sept 20, 2023 Item #2 Page 124 of 256 a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? The potential impacts of the proposed Projects to important farmlands are analyzed in the PEIR (Section 5.1) and 2019 Addendum. As provided, there are only a limited number of areas within Carlsbad that include important farmlands as defined by the California Department of Conservation with the city consisting 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. The proposed improvements would be contained in urbanized landscapes and public rights-of-way and would not have a substantial adverse effect on the remaining agricultural areas within the city. No substantial new information has been presented that shows the Projects would result in more substantial impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? One small Williamson Act contract area is located within Carlsbad, east of Interstate 5 at Palomar Airport Road (City 2015a). This property would be unaffected by the Projects and therefore the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? As described in Section 5.1 of the PEIR, the city’s service area does not include any forest land or timberland zoned for timberland production. This circumstance remains unchanged, and no new or more substantial impacts would result under the proposed Projects. d) Result in the loss of forest land or conversion of forest land to non-forest use? As described under c), the Projects would result in no impacts to forest land or timberland production. e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? As described under a) and c), the proposed Projects would result in no impacts to agricultural resources, forest land, or timberland production. Sept 20, 2023 Item #2 Page 125 of 256 III. Air Quality Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? Yes No No No b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attainment under an applicable federal or state ambient air quality standard? Yes No No No c) Expose sensitive receptors to substantial pollutant concentrations? Yes No No No d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? Yes No No No a) Conflict with or obstruct implementation of the applicable air quality plan? Section 4.2 of the PEIR determined that the Master Plans would not conflict with or obstruct implementation of the Regional Air Quality Strategy or State Implementation Plan and a less than significant impact would occur. The existing regulatory framework governing air quality planning in the city has not substantially changed since the certification of the PEIR. The San Diego Air Basin continues to be in attainment for carbon monoxide (CO), nitrogen dioxide (NO2), lead, and sulfur dioxide (SO2), attainment/unclassifiable for (PM2.5) and (PM10), and non-attainment for ozone (8-hour) with respect to federal air quality standards. With respect to state air quality standards, the San Diego Air Basin continues to be in attainment for CO, NO2, lead, SO2, and non-attainment for ozone, PM2.5 and PM10. The Projects would not result in population growth that would exceed the population projections accounted for in the Regional Air Quality Strategy and State Implementation Plan. Furthermore, the construction and operational characteristics as described in Section 4.2 have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusion of less than significant, as identified in the PEIR, remains accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 126 of 256 As provided in Section 4.2 of the PEIR, construction of the CIP projects proposed under the Master Plans would result in temporary increases in air pollutant emissions. While excavation was not proposed for the Maerkle valve site, excavation as a construction activity was analyzed and included in the PEIR. Impacts related to the site would be consistent with those presented in the PEIR and 2019 Addendum. These emissions would be generated in the form of fugitive dust emissions (PM10 and PM2.5) and ozone precursor emissions (NOx, volatile organic compounds). Operation of heavy equipment and vehicles during the construction phases would generate exhaust emissions from fuel combustion. Fugitive dust emissions would be generated from earth disturbance during site grading and structure demolition, as well as from construction vehicles operating on vacant areas or dirt roadways within or adjacent to CIP construction sites. The city has committed to implementing best management practices (BMPs), identified as project design features in the MMRP, to reduce fugitive dust emissions and other criteria pollutant emissions during construction of CIP projects. The PEIR contemplated the construction of the Master Plan(s) CIP projects would take place over an approximately 23 year period between 2012 and 2035. The PEIR estimated the construction emissions for the overall Master Plan Updates using conservative assumptions, which considered simultaneous construction of multiple projects covered under the Master Plans. The construction parameters as described for the Project would be contained within the conservative scenario described in Section 4.2.3.2 of the PEIR. Based on the fact that emissions calculated at the programmatic level for the Master Plans were determined to be less than significant, it is reasonable to conclude that construction emissions for the proposed Projects would not exceed San Diego Air Pollution Control District’s significance thresholds and therefore would be less than significant. For this reason, no substantial new information has been presented that shows more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attainment under an applicable federal or state ambient air quality standard? The potential impacts associated with a cumulatively considerable net increase of criteria pollutants were analyzed in the PEIR (Section 4.2) and 2019 Addendum. The city has committed to implementing BMPs, identified as project design features in the MMRP, to reduce fugitive dust emissions and other criteria pollutant emissions during construction of the Projects. With the implementation of BMPs contained in the MMRP, the PEIR determined that the Master Plans would result in a less than significant impact. Further, the Projects would be improvements to existing valve facilities that would not result in new sources of operational criteria pollutants. During facility operation, occasional vehicle trips may be required for repair or inspection and periodic maintenance. The PEIR and 2019 Addendum determined operational air pollutant emission impacts associated with the proposed CIP projects would be less than significant. The existing air quality conditions, including the local air basins attainment status, have not substantially changed since the certification of the PEIR. Furthermore, the construction and operational activities of the Projects have not changed substantially from those certified in the PEIR. No substantial new information has been presented that shows more significant impacts would result under the proposed Projects than those originally analyzed in the PEIR or 2019 Addendum and there would be no new Sept 20, 2023 Item #2 Page 127 of 256 significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Expose sensitive receptors to substantial pollutant concentrations? The potential impacts associated with exposure of sensitive receptors to pollutant concentrations were analyzed in the PEIR (Section 4.2) and 2019 Addendum. The PEIR determined that the CIP projects covered under the Master Plans would not expose sensitive receptors to substantial pollutant concentrations and a less than significant impact would occur. The potential for substantial pollutant generation due to construction of the Projects has not changed since the certification of the PEIR. Once installed, the Project components would not generate substantial pollutant concentrations. The construction and operational characteristics of the Projects have not changed substantially compared to the activities included in the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? The potential impacts associated with odors were analyzed in the PEIR (Section 4.2) and 2019 Addendum. The PEIR determined that the Master Plans would not create objectionable odors and a less than significant impact would occur. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. The proposed Project valve improvements, once installed, would not result in emissions such as odors. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 128 of 256 IV. Biological Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Yes No No No b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Wildlife or US Fish and Wildlife Service? Yes No No No c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Yes No No No d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Yes No No No e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Yes No No No f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Yes No No No The discussion below is based in part on a biological survey prepared by HELIX Environmental Planning, Inc. (HELIX 2022a) for the Maerkle valve site, attached to this Addendum as Appendix A. Sept 20, 2023 Item #2 Page 129 of 256 a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Section 4.3, Biological Resources, of the PEIR provides a programmatic evaluation of potential impacts, either directly or through habitat modifications, on plant and wildlife species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service. Appendix B of the PEIR includes a tabular listing of the special status species considered in 2012. An updated species list was requested from the U.S. Fish and Wildlife Service in 2019 to confirm current listings and was included in Appendix B of the 2019 Addendum. Tables 4.3-3 and 4.3-4 in the PEIR identify projects that would occur within Carlsbad and be subject to the conditions of Carlsbad’s Habitat Management Plan (HMP) and associated species avoidance, minimization, and compensatory mitigation requirements. The Carlsbad HMP was in part developed to set aside land in preservation to use as mitigation for future projects. Based on the programmatic evaluation, the special status species with potential to be impacted by CIP projects within Carlsbad are all likely to be covered species or narrow endemic species under the Carlsbad HMP. Species not covered under the Carlsbad HMP are not likely to occur within the CIP project sites. Therefore, species not covered under the Carlsbad HMP are not likely to be adversely affected by CIP projects. Project-level surveys and/or avoidance and minimization measures were proposed for the CIP projects listed in Table 4.3-3 to ensure that the appropriate measures are implemented to address special status species with the potential to occur, including projects that are not covered under the Carlsbad HMP per HMP Appendix B. None of the Projects were identified as requiring surveys or minimization measures. However, due to the change in activities proposed at the Maerkle valve site, a project-specific survey was completed in accordance with Mitigation Measure Bio-1A. Surveys were not conducted for the specific corrosion test station sites as construction activities would occur within existing developed roadways where no sensitive biological resources are present. Direct impacts include the direct take, removal, or displacement of special status species and their habitat through activities such as clearing, grubbing, grading, and other land disturbance activities. Removal of habitat could result in displacement of special status wildlife and less habitat available within a species’ range to carry out vital life history requirements such as breeding, foraging, dispersal, migration, aestivation (i.e., underground dormancy or torpor during the summer) and predator evasion. Construction activities could also result in the removal or trimming of trees and shrubs during the general bird nesting season (January 15 through September 15). Indirect impacts could also result in temporary increases in noise levels, which could adversely affect special status wildlife species occupying adjacent habitats, including nest failure. Impacts to special status species were identified as less than significant with mitigation in the PEIR. Implementation of Mitigation Measures Bio-1D through Bio-1I and Bio-2A at the Maerkle valve site would reduce direct and indirect impacts on special species and their habitat to a less than significant level. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 130 of 256 b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? As evaluated in Section 4.3 of the PEIR, construction of CIP projects has the potential to result in direct impacts to riparian habitat and several types of sensitive natural communities. Habitat loss or disturbance as a consequence of these CIP project construction activities could result in diminishing and degrading of open space areas, reductions, or eliminations of habitat functions and values, and impacts to species, among other adverse impacts. These direct impacts were identified as a significant in the PEIR prior to the implementation of mitigation. Impacts to sensitive vegetation communities at the Maerkle valve site are anticipated to total 0.08 acre. Mitigation would be provided in accordance with the ratios provided in Mitigation Measure Bio-2A at the Lake Calavera Mitigation Bank and would total 0.04 acre of mitigation for impacts to 0.04 acre of coastal sage scrub and 0.04 acre of disturbed habitat (mitigation rounded to the nearest 0.01 acre) (HELIX 2022a). Implementation of Mitigation Measure Bio-2A in would reduce direct impacts on sensitive habitats to a less than significant level. The regulatory requirements have not substantially changed since the certification of the PEIR. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? As evaluated in the programmatic analysis provided in Section 4.3 of the PEIR, the construction of the CIP projects would have the potential to result in direct impacts to riparian and wetland habitat types that could support jurisdictional waters and wetlands. Activities associated with construction of specific CIP projects (see Table 4.3-7 of the PEIR) could be subject to the regulatory jurisdiction of the U.S. Army Corps of Engineers (USACE), Regional Water Quality Control Board (RWQCB), and/or California Department of Fish and Wildlife (CDFW). However, none of the proposed Project sites occur within or adjacent to jurisdictional wetlands. The city is required to prepare and implement BMPs to minimize, control, and treat storm water runoff, fugitive dust, and other pollutants at the CIP construction site. Implementation of these required practices would reduce potential indirect impacts during construction to a less than significant level. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 131 of 256 d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? As provided in Section 4.3 of the PEIR, the proposed CIP projects are proposed within disturbed and developed land that contains existing development and none of the proposed projects are anticipated to adversely affect, either directly or indirectly, the continued function of wildlife movement. The proposed Projects’ footprints would be limited in overall space, and confined, such that wildlife could continue to move through the local area and around the proposed developments. Due to the small size and limited above-ground features proposed as part of the Projects, no adverse effects toward wildlife movement are anticipated to occur. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? The city and CMWD are required to comply with the Carlsbad HMP and provisions of the Carlsbad Local Coastal Plan, including the Coastal Resource Protection Overlay Zone Ordinance; however, the proposed Projects are not within the Coastal Zone and implementation of the proposed Master Plans were determined not to conflict with the adopted Coastal Resource Protection Overlay Zone Ordinance. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? As evaluated above, the Projects could result in potential impacts to sensitive species and habitat that are addressed within the Carlsbad HMP. Based on the potential for impacts to sensitive species at the Maerkle valve site, a minor HMP Permit from the city would be required to approve and implement the Projects in accordance with Carlsbad Municipal Code Chapter 21.210. The Maerkle valve improvement is consistent with the Carlsbad HMP because it has been sited within existing disturbed and developed land that is subject to regular maintenance, and would only impact a very small (less than 0.1 acre) area of previously restored Diegan coastal sage scrub. Mitigation would be provided for direct and indirect impacts consistent with the Carlsbad HMP and PEIR, as discussed above. No substantial new information has been presented that shows more significant impacts would result under the Projects than those originally analyzed in the PEIR and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 132 of 256 V. Cultural Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? Yes No No No b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Yes No No No c) Disturb any human remains, including those interred outside of dedicated cemeteries? Yes No No No The discussion below is based on a cultural report prepared by HELIX Environmental Planning, Inc. for the Maerkle site, attached to this Addendum as Appendix B (HELIX 2022b). a) Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? Section 4.4, Cultural and Paleontological Resources, of the PEIR provides a programmatic assessment of the potential impacts to historic resources based on the CIP projects outlined in the 2012 Master Plans. The PEIR notes various existing built-environment historical resources (buildings or structures aged 45 years old or older) and numerous archaeological sites within its study area. The PEIR included a cultural resources records search to evaluate the presence of known historical and archaeological resources for areas potentially impacted by the Master Plans. One sewer project included in the 2019 Addendum would be located in proximity to a historical resource; however, the project would not result in the disturbance or alteration of the historical resource. The PEIR and 2019 Addendum concluded that the Master Plan Updates would result in less than significant impacts to historical resources. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Section 4.4 of the PEIR provides an assessment of potential impacts of the Master Plan improvements to known and undocumented archaeological resources. Known cultural resources that may be affected by the construction of proposed CIP project sites are listed by Master Plan improvements in Tables 4.4-3 to Sept 20, 2023 Item #2 Page 133 of 256 4.4-5 of the PEIR. Additionally, the PEIR notes a high archaeological resource sensitivity for its entire study area. The El Fuerte (21) and Maerkle (R7) sites were identified as sites within previously disturbed setting such that archaeological resources would have been removed or destroyed by previous construction. A table that identifies which CIP projects would have the potential to impact each resource is available in Confidential Appendix D2. This appendix is available to qualified viewers at the City of Carlsbad, 1635 Faraday Avenue, Carlsbad, CA 92008. These resources are predominately prehistoric archaeological sites of varying sizes and occupancy duration and exhibit prehistoric material culture through midden and scatters of lithic and groundstone tools. In addition, some of the identified sites in Tables 4.4-3 to 4.4-5 are considered historical resources pursuant to CEQA because they retain the potential to yield data important to prehistory or history (Criterion 4 of the California Register of Historic Resources). The PEIR concluded that the Master Plan improvements could result in a potentially significant impact to archaeological resources in the absence of mitigation. With the incorporation of Mitigation Measure Cul-1, this impact would be reduced to a level of less than significant. A Project-specific cultural resources report was prepared in accordance with Mitigation Measure Cul-1 for the Maerkle valve site due to the proposed excavation activity. The El Fuerte site was previously determined in the PEIR and 2019 Addendum to not require mitigation related to cultural resources due to its disturbed location. The additional corrosion testing sites would also be located within the existing roadway and sidewalks, which have previously been disturbed. The records search for the Maerkle valve site resulted in the identification of ten cultural resources within the records search limits, all of which are located a quarter-mile or more from the report’s Study Area. In general, the resources included shell scatters, artifact scatters, milling areas, and the historic Rancho de los Quiotes to Mission San Luis Rey trail. The Native American Heritage Commission (NAHC) search of their Sacred Land Files indicated that tribal cultural resources may be present and noted to contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians for additional information regarding the resources. CMWD met with representatives from the San Luis Rey Band and discussed the Maerkle site conditions and proposed activities. The San Luis Rey Band requested that spot-check monitoring occur for Maerkle valve site due to the cultural sensitivity of the project region. No response from the La Jolla Band was received in response to CMWD outreach. The review of aerial imagery undertaken as part of the project-level cultural resources review indicates that the entirety of the Maerkle valve project area, as well as the area surrounding it, was rough graded in 1990 for the upgrade and expansion of the Maerkle Reservoir, which included an installation of a buried tank that is situated directly north of the project area. Additionally, the review of geologic and soil conditions for the project area do not indicate the presence of young alluvium soils within the Study Area, which typically contain a higher potential for buried cultural resources to be present. As such, it is likely the case that the grading that occurred in 1990 removed any potential for cultural resources to still be present within the project area. Per Cul-1 (2) in the PEIR MMRP, for those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. While the cultural resources survey that encompassed the Study Area was conducted over 30 years ago, the Study Area is within a previously disturbed area and is not in close proximity to a known cultural resource. Therefore, no further cultural resources work, including a project-level Phase I cultural resources survey, was recommended for activity at the Maerkle valve site. However, while a project-level Phase I survey is not necessary for the Maerkle valve project area, cultural resources monitoring will occur for the Maerkle valve site, based on the concerns and recommendations provided by the San Luis Rey Band of Mission Indians. During vault excavation, spot check monitoring would be Sept 20, 2023 Item #2 Page 134 of 256 required. Full-time monitoring would not be required for vault excavation and no monitoring would be required for Maerkle valve replacements. Since the certification of the PEIR, the city adopted the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017), which updated and replaced the city’s 1990 Cultural Resource Guidelines. The 2017 guidelines are incorporated by reference into the 2019 Addendum MMRP to reflect the city’s established standards of performance for cultural resources investigations following the city’s General Plan Update (2015a), the adoption of Assembly Bill 52 in 2014, and the corresponding amendments to Appendix G of the CEQA Guidelines (as amended). With the incorporation by reference of the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017), the Projects would have a less than significant impact. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR or 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Disturb any human remains, including those interred outside of dedicated cemeteries? Section 4.4 of the PEIR documents the presence of formal cemeteries within the CMWD service area; however, the section explains that none of the CIP projects are proposed within their boundaries. Therefore, it is not expected that construction activities at CIP sites would disturb formal cemeteries. Sections 15064.5(d) and (e) of the CEQA Guidelines assign special importance to human remains and specifies procedures to be used when Native American remains are discovered. As provided in the PEIR, these procedures are detailed under Public Resources Code (PRC) Section 5097.98. The disturbance of any human remains is considered a significant impact, regardless of archaeological significance or association. Any ground disturbing activities, including grading, trenching, and excavation during construction of the Projects, would have the potential to unintentionally disturb human remains, resulting in a significant impact. Implementation of the required protocol in accordance with PRC Section 5097.98 and California State Health and Safety Code Section 7050.5, to be followed upon unintentional disturbance of human remains, would minimize potential impacts on human remains to a level of less than significant. The construction and operational characteristics of the proposed Projects have not changed substantially since the certification of the PEIR or 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum and there would be no new impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 135 of 256 VI. Energy Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Yes No No No b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? Yes No No No a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Section 4.5, Energy, of the PEIR provides an assessment of the Master Plans effects on existing water, sanitary sewer, and recycled water facilities energy use. The PEIR concluded that the Master Plans would not generate a substantial net increase in vehicle trips based on pre-existing maintenance activities. The proposed valve replacements and corrosion testing stations at existing facilities would not result in an increase in energy demand at these facilities compared to existing conditions. The PEIR includes standard BMPs, identified as project design features in the adopted MMRP, to minimize energy consumption during construction: • Electrical power will be supplied from commercial power supply wherever feasible, to avoid or minimize the use of engine-driven generators; and • Trucks and equipment will not idle for more than 15 minutes when not in service. The city and CMWD conduct routine maintenance on all infrastructure facilities and would incorporate the proposed Projects into the maintenance schedule. The PEIR noted a potential total net increase in electricity demand of 3.96 kilowatt hour (kWh) at buildout of the sewer, water, and recycled water systems, which was approximately double existing electricity demand in 2012. Total energy use as it relates to water, sanitary sewer, and recycled water is largely a function of the city’s water demands, which in 2012 was projected to be 20.8 mgd (23,296 afy) in 2035 and increased to 21.4 mgd (23,968 afy) at buildout. The 2019 Addendum stated that based on updates to the city’s growth, the updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), comparatively lower than the previous predictions. Therefore, the projected energy demands under the Projects, as provided in the 2019 Addendum, would be less than analyzed in 2012 and the impact would be less than significant. Sept 20, 2023 Item #2 Page 136 of 256 No substantial new information has been presented that shows more significant impacts would result under the Projects than those originally analyzed in the PEIR or 2019 Addendum and there would be no new significant impacts. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? As provided in a), the CIP projects described in the 2019 Addendum would result in a lower water demand than considered in the PEIR. In addition, these projected estimates are consistent with the city’s General Plan Update (2015a) and policies related to energy efficiency. For these reasons, the Projects would not conflict with plans or policies adopted for the purposes of promoting energy efficiency, and the impact is less than significant. VII. Geology and Soils Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Directly or indirectly cause 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? Refer to Division of Mines and Geology Special Publication 42. Yes No No No ii. Strong seismic ground shaking? Yes No No No iii. Seismic-related ground failure, including liquefaction? Yes No No No iv. Landslides? Yes No No No b) Result in substantial soil erosion or the loss of topsoil? Yes No No No c) 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? Yes No No No Sept 20, 2023 Item #2 Page 137 of 256 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? Yes No No No e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? Yes No No No f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Yes No No No a) Directly or indirectly cause 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? Refer to Division of Mines and Geology Special Publication 42? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving rupture of an earthquake fault were analyzed in the PEIR (Section 4.6, Geology and Soils) and 2019 Addendum. The PEIR determined that surface rupture as a result of seismic activity is unlikely throughout the CMWD service area and no impact would occur. ii. Strong seismic ground shaking? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving strong seismic shaking were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would not exacerbate existing hazards related to strong seismic shaking. The proposed Projects would be required to comply with the city’s engineering standards and standard engineering practices. As a result, this impact would be less than significant. iii. Seismic-related ground failure, including liquefaction? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving seismic-related ground failure were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact and would not exacerbate existing hazards related to seismic-related ground failure. The Projects would be required to comply with the city’s standards and standard engineering practices. Sept 20, 2023 Item #2 Page 138 of 256 iv. Landslides? The potential impacts associated with exposure of people or structures to potential substantial adverse effects involving landslides were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact associated with landslides. Individual projects would be required to comply with the city’s engineering standards and grading requirements, which would minimize any hazards related to cut and fill slopes and related landslide hazards. These requirements would minimize any impacts to less than significant levels. In summary, the improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. For these reasons, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Result in substantial soil erosion or the loss of topsoil? The potential impacts associated with soil erosion were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact associated with soil erosion. The Projects’ construction activities would be regulated under the NPDES General Permit for Discharges of Storm Water Runoff Associated with Construction Activity (General Construction Permit, NPDES Order No. 2012-0006-DWQ). In addition, the city would comply with applicable grading ordinance(s) and/or erosion control requirements. Compliance with existing regulations would minimize the potential for erosion during construction such that the impact is considered less than significant. The physical improvements proposed as part of the Projects have not substantially changed from the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. For these reasons, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) 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? As described in a), the PEIR considered geologic hazards as it relates to the proposed Master Plan improvements and determined that a less than significant impact would result as it relates to hazards from unstable geologic units or soils. Projects would be required to comply with city standards and standard engineering practices. Compliance with existing state and local regulations would minimize potential impacts to less than significant. The physical geologic and soil conditions in the areas of the Projects have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. For these reasons, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 139 of 256 d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? The potential impacts associated with expansive soils were analyzed in the PEIR (Section 4.6) and 2019 Addendum. The PEIR determined that the Master Plans would result in a less than significant impact associated with expansive soils. Projects would be required to comply with the city’s standards and standard engineering practices. The physical improvements proposed for the Projects have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? The potential impacts associated with septic tanks or alternative wastewater disposal systems were analyzed in the PEIR (Section 4.6) and 2019 Addendum. Similar to the adopted Master Plans and 2019 Addendum, alternative wastewater disposal systems and septic tanks are not a component of the proposed Projects and, therefore, no impact would result. f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Section 4.4, Cultural and Paleontological Resources, of the PEIR provided an analysis of the potential impacts of the Master Plan improvements to paleontological resources. Excavation and construction activities associated with proposed CIP projects have the potential to disturb or destroy paleontological resources depending on their location within the context of geologic formations with moderate and high paleontological sensitivity. Figure 4 and Table 1 of the city’s adopted 2017 Guidelines identify the moderate and high paleontological sensitive geologic formations within the city. The Point Loma formation, Santiago formation, and Bay Point formation are identified as high paleontological sensitivity, and the Lusardi, Delmar, late to middle Pleistocene, late Holocene marine beach, and late Holocene paralic estuarine deposits are identified as moderate sensitivity. Implementation of Mitigation Measure Pal-1 would minimize potential impacts associated with the disturbance of paleontological resources. Pal-1 was not identified in the 2019 Addendum as applicable to any of the proposed Project sites (W-9, W-13, or 50071). The Maerkle valve site (W-9) is located within a low sensitivity area according to Figure 4 of the city’s 2017 Guidelines. The additional corrosion testing site components (50071) proposed at the El Fuerte valve site (W-13) would be within the area previously trenched for the installation of the existing pipe and would not result in a disturbance to paleontological resources. Therefore, implementation of Pal-1 would not be required and impacts associated with the disturbance of paleontological resources would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 140 of 256 VIII. Greenhouse Gas Emissions Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Yes No No No b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Yes No No No a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Section 4.7, Greenhouse Gas Emissions, of the PEIR provides an analysis of the potential for the Master Plan improvements to result in the generation of GHG emissions. Since the preparation of the PEIR, the city adopted a CAP (September 2015) that outlines actions the city will undertake to achieve its proportional share of GHG reductions. The CAP identified project screening thresholds based on guidance from the California Air Pollution Control Officers Association. The city determined that new development projects emitting less than 900 metric tons (MT) carbon dioxide equivalent (CO2e) annual GHG would not contribute considerably to cumulative climate change impacts (City 2015b). If a proposed project exceeds the CAP’s 900 MT CO2e screening threshold, the project proponent must complete the CAP Consistency Checklist to demonstrate consistency with the CAP, or a self-developed GHG-reduction program. The city analyzed the Master Plan Updates proposed in the 2019 Addendum for GHG impacts using the CAP’s screening threshold of 900 MT of CO2e per year (City 2015b). Construction of the Projects would result in temporary emissions of GHG from the operation of construction equipment and from worker and building supply vendor vehicles. Equipment that is associated with construction activity includes dozers, rollers, dewatering pumps, backhoes, loaders, delivery, and haul trucks. The PEIR determined that the most conservative construction scenario, where all projects would be constructed simultaneously and completed in seven months, would result in GHG emissions of 959 MT CO2e. The 2012 Master Plan included the construction of 50 separate projects while the 2019 Master Plan Updates included the construction of 27 separate projects. Therefore, the GHG emissions of 959 MT CO2e included in the PEIR and 2019 Addendum is conservative for the construction of the proposed Projects. Projected electrical demand in the PEIR was based on projected water demand, which was updated in the 2019 Addendum based on updates to the city’s growth. The updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), which would reduce the increased electrical demand to Sept 20, 2023 Item #2 Page 141 of 256 1.0 million kWh. Using a carbon intensity factor of 630 pounds of CO2e per megawatt hour, the operational GHG associated with the 2019 Master Plan Updates was projected to be 257 MT CO2e per year. The total annual GHG emissions from construction and operation of the 2019 Master Plan Updates was estimated at 289 MT CO2e. This is below the 900 MT of CO2e per year screening threshold established by the city. No components of the proposed Projects would substantially change construction or operational GHG emissions that were assumed for the Projects under the 2019 Addendum. The new valves would replace existing components and consume similar amounts of energy. For this reason, the impact would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases? The city’s CAP is considered a qualified GHG reduction plan in accordance with CEQA Guidelines Section 15183.5. The Projects would be consistent with Measure N of the city’s CAP: Reduce GHG Intensity of Water Utilities Supply Conveyance, Treatment, and Distribution. The Projects would result in GHG emission reductions from changes in the efficiency of water utilities (including water supply, wastewater, and recycled water) conveyance, treatment, and distribution facilities within the city. The City Council adopted Policy 71: Energy Conservation and Management, in July 2006. This Policy outlines measures to help Carlsbad reach the goals set out by the city’s Energy Conservation and Management Program, including reducing demand on the energy grid. The Projects would assist the city to reduce demand on the energy grid from the changes in the efficiency of water utilities conveyance, treatment, and distribution facilities within the city. As provided in a) and in this response, the Projects are consistent with the CAP because they would not exceed the 900 MT of CO2e per year screening threshold established by the city and would result in GHG emission reductions. This response also demonstrates consistency with City Council Policy 71 due to changes in efficiency of water utilities. Sept 20, 2023 Item #2 Page 142 of 256 IX. Hazards and Hazardous Materials Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Yes No No No b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Yes No No No c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Yes No No No d) 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 the environment? Yes No No No e) For a project located 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 or excessive noise for people residing or working in the project area? Yes No No No f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Yes No No No g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? Yes No No No Sept 20, 2023 Item #2 Page 143 of 256 a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? The PEIR (Section 4.8, Hazards and Hazardous Materials) and 2019 Addendum provided assessments of the potential for the routine use, transport, or disposal of hazardous materials. As provided, there are multiple federal, state, and local laws and regulations, such as Resource Conservation and Recovery Act, Title 22 of the California Code of Regulations, the Hazardous Waste Control Law, Hazardous Materials Transportation Act, and Hazardous Material Business Plans, that the Projects are required to comply with by law. Therefore, impacts associated with the use, transport, and disposal of hazardous materials generated from construction and operational activities were determined to be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? The PEIR (Section 4.8) and 2019 Addendum provided assessments of the potential for the accidental release of documented and undocumented sources of hazardous materials. As provided in the PEIR, the city has committed to the BMPs listed as project design features in the MMRP for hazardous materials. These included a site-specific hazardous materials record search for the locations and type of hazardous materials for each CIP project and, if required, a site assessment. Conducting a hazardous materials database search and environmental site assessment prior to any ground-disturbing activities associated with the construction of CIP sites would identify hazardous materials that could be encountered during CIP construction activities. With these precautions, the impact was concluded to be less than significant. The Project sites were searched for hazardous material sites on the databases maintained by the State Water Resources Control Board (SWRCB) and California Department of Toxic Substances Control (DTSC). No hazardous materials sites were identified in the vicinity of the Project sites, and therefore impacts related to potential hazardous materials would be less than significant (SWRCB 2022; DTSC 2022). The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? The PEIR (Section 4.8) and 2019 Addendum provided assessments of the CIP projects and potential for the emission of hazardous materials within a quarter mile of a school. As provided, the activities and CIP components would be operated in compliance with applicable regulations that would minimize foreseeable risks of an accident that could create a hazard to the public or environment. Therefore, Sept 20, 2023 Item #2 Page 144 of 256 implementation of the Projects would not result in hazardous emissions within one-quarter mile of an existing or proposed school and impacts would be less than significant. d) 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 the environment? The potential impacts associated with the disturbance of listed hazardous materials sites were analyzed in the PEIR (Section 4.8) and 2019 Addendum. As discussed in response b), the specific sites of the Projects were searched for hazardous materials sites compiled pursuant to Government Code 65962.5 and no potential hazards related to the Projects were identified. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) For a project located 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 or excessive noise for people residing or working in the project area? The potential impacts associated with airport safety hazards were analyzed in the PEIR (Section 4.8) and 2019 Addendum. The PEIR and 2019 Addendum determined that no impact would occur. No substantial new information has been presented that shows the Projects would result in substantially more severe impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? The PEIR (Section 4.8) and 2019 Addendum evaluated issues related to emergency response and evacuation. The PEIR noted that construction activities associated with the Master Plans, particularly excavation and trenching activities associated with pipeline extensions or other improvements that are within roadway rights-of-way, may result in temporary, construction-related lane and road closures or detours. As provided in the PEIR, the city has committed to preparing a traffic control plan for applicable CIP projects and coordinating with the cities of Oceanside, Vista, and San Marcos. With implementation of a traffic control plan for construction activities within roadways, the Projects would result in less than significant impacts on emergency response or evacuation plans. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 145 of 256 g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires? The PEIR (Section 4.8) and 2019 Addendum included analysis of wildfire hazards. As provided, CMWD service area includes mostly urbanized areas; however, portions of the city service area are located in areas classified as Very High Fire Hazard Severity Zones; particularly in the eastern area of the service area (California Department of Forestry and Fire Protection [CAL FIRE] 2009). Only the Maerkle valve site of the Project is located within a Very High Fire Hazard Severity Zone. As provided in the PEIR, construction and design of all CIP projects would comply with the Uniform Fire Code (Title 24 Code of Federal Regulations, Part 9), which requires installation of sprinkler systems, fire- resistant building materials, standard roadway access widths, and other features to ensure that all above-ground structures are constructed with all reasonable fire safety features. Additionally, the city has committed to the multiple design features to minimize impacts related to wildfire: • Fire safety information will be disseminated to construction crews during regular safety meetings. Fire management techniques will be applied during project construction as deemed necessary by the lead agency and depending on-site vegetation and vegetation of surrounding areas. • A brush management plan will be incorporated during project construction by the city, CMWD, or a contractor, as necessary. Construction within areas of dense foliage during dry conditions will be avoided, when feasible. • In cases where avoidance is not feasible, necessary brush fire prevention and management practices will be incorporated. Specifics of the brush management program will be determined as site plans for the project are finalized. Preparation of a brush management plan and dissemination of fire safety information to construction crews would minimize hazards to a level of less than significant. As such, the Projects 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. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 146 of 256 X. Hydrology and Water Quality Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? Yes No No No b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? Yes No No No c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: i. Result in substantial erosion or siltation on- or off-site? Yes No No No ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off- site? Yes No No No iii. Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional resources of polluted runoff? Yes No No No iv. Impede or redirect flood flows? Yes No No No d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? Yes No No No e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? Yes No No No Sept 20, 2023 Item #2 Page 147 of 256 a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? The PEIR (Section 4.9, Hydrology and Water Quality) and 2019 Addendum provide assessments of the potential for impacts associated with the Master Plan improvements to result in a violation of water quality standards or waste discharge requirements. During construction, there is potential for sediment and other construction-related contaminants to enter waterways from runoff. The PEIR determined that the Master Plans would result in a less than significant water quality impact based on the pre-existing NPDES and local grading and erosion ordinance requirements. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? The potential impacts associated with depletion of groundwater supplies were analyzed in the PEIR (Section 4.9) and 2019 Addendum. Construction activities associated with the Master Plans may require temporary dewatering. The proposed Projects would not involve any groundwater extraction. The PEIR determined that the Master Plans would result in a less than significant impact associated with depletion of groundwater supplies. This circumstance remains unchanged under the Projects based on the overall reduction in water demands. The construction and operational characteristics of the Projects have not substantially changed since the certification of the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: The potential for impacts associated with the CIP improvements to result in alteration of existing drainage patterns and flood hazards were analyzed in the PEIR (Section 4.9) and 2019 Addendum. The proposed improvements at the Maerkle valve site may involve excavation/grading, vegetation trimming or removal activities, and could result in temporary changes to existing drainage patterns during construction. The PEIR determined that the Master Plan improvements would result in less than significant impacts to existing drainage patterns and flood hazards with conformance to existing NPDES and local grading and erosion control requirements. Sept 20, 2023 Item #2 Page 148 of 256 i. Result in substantial erosion or siltation on- or off-site? As provided in a), the improvements covered under the Projects would be subject to NPDES and local grading and erosion control requirements. As a result, the Projects would not result in substantial erosion or siltation on- or off-site. ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off- site? As noted above, the Projects would be subject to NPDES and local grading and erosion control requirements. As a result, the Projects would not substantially increase the rate or amount of surface runoff in a manner which would result in flooding on-or off-site. iii. Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional resources of polluted runoff? The Projects would result in minor additions to impervious surfaces; however, these additions would not be of a scale that could create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. iv. Impede or redirect flood flows? No changes in channel structures are proposed that could impede or redirect flood flows. Alterations to impervious surfaces would not be of an extent that could impede or redirect flood flows. d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? The potential impacts associated with inundation by seiche, tsunami, or mudflow were analyzed in the PEIR (Section 4.9) and 2019 Addendum. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? See responses to a) and b). As provided, the Projects would result in less than significant impacts Sept 20, 2023 Item #2 Page 149 of 256 XI. Land Use and Planning Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Physically divide an established community? Yes No No No b) Cause significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? Yes No No No a) Physically divide an established community? Section 4.10, Land Use and Planning, of the PEIR provides an assessment of the Master Plan’s potential to result in the division of established communities. The PEIR and 2019 Addendum determined that the CIP projects, including the Projects as initially proposed, would not divide an established community. The Projects would be constructed on existing public road rights-of-way, a small easement, and existing city facilities. These land use conditions remain unchanged with the proposed Projects. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Cause significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? As discussed in Section 4.10 of the PEIR, the Master Plans’ CIPs are designed to provide Carlsbad with plans for the development of water utilities to meet the present and future needs of the projected growth and land uses within each service area. Implementation of the Master Plans would not induce any unplanned growth that would be inconsistent with the city’s General Plan, which was formally updated in 2015, or its Growth Management Plan. Future projects would be required to comply with all applicable land use regulations in order to obtain project approval and would be further evaluated at the time of project design and review. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 150 of 256 XII. Mineral Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Yes No No No b) 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? Yes No No No a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Section 5.1, Effects Found Not Significant, of the PEIR includes the topic of Mineral Resources. As provided, impacts to mineral resources were determined to have no impact because the improvements were driven by new growth and ongoing condition assessment of existing infrastructure. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) 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? See response a). No impact would result from the Projects. Sept 20, 2023 Item #2 Page 151 of 256 XIII. Noise Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project result in: a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Yes Yes Yes No b) Generation of excessive groundborne vibration or groundborne noise levels? Yes Yes Yes No c) For a project located within the vicinity of a private airstrip or 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 expose people residing or working in the project area to excessive noise levels? Yes Yes Yes No a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Section 4.11, Noise, of the PEIR provides an assessment of the potential impacts to noise sensitive land uses resulting from the construction and long-term operation of the Master Plan improvements. As noted in the PEIR and 2019 Addendum, maintenance trips would be spread across all facilities, including the Projects, and would not be concentrated on a specific roadway. Due to the minimal number and geographic distribution of vehicular trips associated with the maintenance of the CIP projects overall, transportation noise increases would be negligible. Under the Projects, these circumstances would remain unchanged and would result in less than significant permanent increases in ambient noise associated with transportation noise sources. The city has committed to ensuring that operating equipment will be designed to comply with all applicable local, state, and federal regulations. The Projects would not generate operational noise once installed and would not result in a substantial increase in ambient noise levels. According to the PEIR and 2019 Addendum, construction of the CIP projects would result in temporary increases in ambient noise levels. Construction activities associated with the Projects would involve the use of heavy equipment during vegetation clearing, trenching, and installation of equipment, such as valves and corrosion test station equipment. The magnitude of the impact would depend on the type of Sept 20, 2023 Item #2 Page 152 of 256 construction activity, type of construction equipment, duration of the construction phase, distance between the noise source and receiver, and any intervening topography. As provided, sound levels of typical construction equipment range from 60 decibels to 90 decibels at 50 feet from the source (U.S. Department of Transportation 2008). The PEIR included construction BMPs, identified as project design features in the MMRP, to minimize noise effects to surrounding neighborhoods. These measures are included in the city’s MMRP. The construction activities proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Generation of excessive groundborne vibration or groundborne noise levels? The PEIR (Section 4.11, Noise) and 2019 Addendum provide assessments of the potential vibration impacts to sensitive land uses resulting from the construction and long-term operation of the CIP improvements. Vibration sources associated with implementation of the Projects would be generated primarily from construction. Once installed, the Projects would include passive uses that do not generate substantial levels of vibration. As provided in the PEIR, construction-related vibration would have the potential to impact nearby structures and vibration-sensitive equipment and operations. The level of vibration generated from construction activities would depend on multiple factors including soil type, distance, and the energy- generating capability of the construction equipment. The PEIR’s MMRP included measures for construction to minimize vibration effects to surrounding neighborhoods. The construction activities proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) For a project located within the vicinity of a private airstrip or 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 expose people residing or working in the project area to excessive noise levels? The Projects would be located within the McClellan-Palomar Airport Influence Area but are not in the identified airport noise contours. The Projects’ improvements do not involve any features for human occupancy that would result in regular exposure to aircraft noise from McClellan-Palomar Airport. Therefore, impacts would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 153 of 256 XIV. Population and Housing Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? Yes No No No b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? Yes No No No a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of population and housing. As provided in the PEIR and 2019 Addendum, the Projects rely on population projections published in the Carlsbad Growth Management Plan and Growth Database, San Diego Association of Governments population projections, and the master plans from neighboring agencies. Therefore, the Projects would not generate additional population or cumulatively exceed official regional or local population projections. These circumstances remain unchanged based on the reduced water demand projections for the Projects included under the 2019 Addendum when compared to the 2012 PEIR. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? The Projects’ improvements would be constructed in existing and future dedicated public roadway rights-of-way, a small easement, and city-owned properties and would not require the displacement or relocation of existing residences. No impact would result. Sept 20, 2023 Item #2 Page 154 of 256 XV. Public Services Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: a) Fire protection? Yes No No No b) Police protection? Yes No No No c) Schools? Yes No No No d) Parks? Yes No No No e) Other public facilities? Yes No No No a) Fire protection? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of the potential impacts of the Master Plans to public services, including fire protection. As provided in the PEIR and 2019 Addendum, the proposed Projects do not contain any residential uses or any other land uses that would result in an increased demand for public services. Additionally, the Projects would not exceed official regional or local population projections. Similar to the adopted Master Plans and Master Plans Updates, the size, capacity, and location of all facilities under the Projects would be based on the population and land use analysis based on forecasted growth identified in the Carlsbad General Plan (2015a), and systems would be sized appropriately to serve projected service populations. For these reasons, no impacts to public services, including fire protection services, would result. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Police protection? See response a). No impact would result to existing police services. Sept 20, 2023 Item #2 Page 155 of 256 c) Schools? See response a). No impact would result to schools or educational services. d) Parks? See response a). No impact would result to parks or recreational facilities. e) Other public facilities? See response a). No impact would result to other public facilities, such as libraries. XVI. Recreation Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Yes No No No b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Yes No No No a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of the potential impacts of the Master Plans to recreation. As provided in the PEIR and 2019 Addendum, the approved CIP projects do not include any proposed residential uses or new recreational facilities or parks and their implementation would not impact the use of parks or other recreational facilities and would not require the construction or expansion of new such facilities. For this reason, the PEIR and 2019 Addendum concluded that no impact would result. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this Sept 20, 2023 Item #2 Page 156 of 256 analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? See response a). No impact would result. XVII. Transportation Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? Yes No No No b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? Yes No No No c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Yes No No No d) Result in inadequate emergency access? Yes No No No a) Conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? Section 4.12, Transportation/Traffic, of the PEIR provides an analysis of the proposed improvements covered under the adopted Master Plans. As described in in the PEIR and 2019 Addendum, the construction of the improvements would generate construction-related trips. However, construction traffic would only affect a limited area of the city in which they were located for a short time during construction of a particular project. The PEIR and 2019 Addendum determined that impacts related to temporary construction traffic would be less than significant with the incorporation of a traffic control plan during construction. Implementation of a traffic control plan is identified as a project design feature in the MMRP. Operation of the infrastructure improvements would not include substantial traffic generating uses beyond existing maintenance conditions. Due to the low volume of traffic generated by the proposed Project improvements (e.g., temporary construction-related trips, periodic inspections, and maintenance), the improvements would not Sept 20, 2023 Item #2 Page 157 of 256 degrade the traffic level of service in the vicinity or conflict with any applicable plans establishing measures of effectiveness for the performance of a circulation system. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? The Projects do not include new traffic generating uses that would increase vehicle trips beyond existing conditions. The PEIR and 2019 Addendum determined that the improvements would not conflict with CEQA Guidelines Section 15064.3(b) and no impact would occur. c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The potential impacts associated with hazards due to a design feature were analyzed in the PEIR (Section 4.12) and 2019 Addendum. The PEIR and 2019 Addendum determined that impacts related to temporary traffic related hazards and local driveway access were less than significant with the incorporation of traffic control planning during construction. Implementation of a traffic control plan is identified as a project design feature in the adopted MMRP. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. The conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. d) Result in inadequate emergency access? Section 4.8 of the PEIR evaluated issues related to emergency response and evacuation. The PEIR and 2019 Addendum noted that construction activities associated with the CIP projects, particularly excavation and trenching activities associated with pipeline extensions or other improvements that are within roadway rights-of-way, may result in temporary, construction-related lane and road closures or detours. The El Fuerte site improvements would include construction in the roadway right-of-way and may require temporary closure of a traffic lane. As provided in the PEIR and 2019 Addendum, the city has committed to preparing a traffic control plan for applicable CIP projects. Implementation of a traffic control plan is identified as a project design feature in the MMRP. With implementation of a traffic control plan, the Projects would result in less than significant impacts on emergency response or evacuation plans. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. Sept 20, 2023 Item #2 Page 158 of 256 XVIII. Tribal Cultural Resources Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: i. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k), or Yes No No No ii. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. Yes No No No a) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: i. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? Section 4.4, Cultural and Paleontological Resources, of the PEIR provides an assessment of potential impacts of the Master Plan improvements to known and undocumented archaeological resources. Since Sept 20, 2023 Item #2 Page 159 of 256 the certification of the PEIR, the city has updated its Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017) to reflect the city’s established standards of performance for cultural resources investigations following the city’s General Plan Update (2015a), the adoption of Assembly Bill 52 in 2014, and the corresponding amendments to Appendix G of the CEQA Guidelines (as amended). The city implemented several administrative updates to the PEIR’s adopted MMRP in the 2019 Addendum. These updates included updated CIP project references and the incorporation by reference of the city’s Tribal, Cultural, and Paleontological Resources Guidelines (2017). The NAHC was contacted for a Sacred Lands File search of the Maerkle valve site on March 10, 2022, to which the NAHC responded in a letter dated April 26, 2022 that the results were positive. The NAHC further noted to contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians for additional information regarding the positive results. No response from the La Jolla Band was received in response to CMWD outreach. CMWD met with representatives from the San Luis Rey Band and discussed the Maerkle site conditions and proposed activities. The San Luis Rey Band requested that spot-check monitoring occur for Maerkle valve site due to the cultural sensitivity of the project region. During vault excavation, spot check monitoring would be required. Full-time monitoring would not be required for vault excavation and no monitoring would be required for Maerkle pipeline replacements. Monitoring activities would be consistent with the 2017 guidelines to ensure potential impacts remain less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. ii. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe? Since the certification of the PEIR, the city adopted the 2017 guidelines to reflect the city’s established standards of performance for cultural resources investigations following the city’s General Plan Update (2015a), the adoption of Assembly Bill 52 in 2014, and the corresponding amendments to Appendix G of the CEQA Guidelines (as amended). As discussed in a), the NAHC indicated that tribal cultural resources may be present at the Maerkle valve site. Spot check monitoring would be conducted during vault excavation, as discussed with the San Luis Rey Band, and described above. Monitoring would not be required at the El Fuerte valve site based on the analysis provided in the PEIR and 2019 Addendum. Implementation of the preferred treatment options and mitigation measures, as detailed in the 2017 guidelines and 2019 Addendum, would ensure potential impacts on tribal cultural resources remain less than significant. Sections 15064.5(d) and (e) of the CEQA Guidelines assign special importance to human remains and specifies procedures to be used when Native American remains are discovered. As provided in Section 4.4 of the PEIR, these procedures are detailed under PRC, Section 5097.98. Any ground Sept 20, 2023 Item #2 Page 160 of 256 disturbing activities associated with implementation of the Projects, including grading, trenching, and excavation during construction of the Projects, would have the potential to unintentionally disturb human remains, resulting in a significant impact. Implementation of the required protocol in accordance with PRC Section 5097.98 and California State Health and Safety Code Section 7050.5, to be followed upon unintentional disturbance of human remains, in conjunction with Standard Treatment Measures 5 and 11 from the city’s 2017 guidelines would ensure potential impacts on human remains remain less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. XIX. Utilities and Service Systems Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? Would the project: a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? Yes No No No b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? Yes No No No c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? Yes No No No d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Yes No No No Sept 20, 2023 Item #2 Page 161 of 256 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? Yes No No No a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? Section 5.1, Effects Found Not Significant, of the PEIR includes a discussion of the potential impacts of the Master Plans on existing utilities and service systems. As provided in the PEIR and 2019 Addendum, a primary purpose of the updating the Master Plans is to ensure adequate, effective, reliable, equitable and fiscally sound water, sewer, and recycled water service to current and projected future residential, commercial, and industrial customers through 2040. The Master Plans respond to projected growth in the service areas (refer to Population and Housing above) and would distribute existing and planned water supplies to meet existing and projected demand. Implementation of the Master Plans would not directly result in the need for new or expanded water and sewer supplies by introducing people or development to an area. The environmental impacts associated with the construction and operation of the proposed Projects are described throughout Section 4.2 of this Addendum. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? As provided in the 2019 Addendum, the Master Plan Updates were projected to result in a reduction in overall water use from 2012. The city’s water demands in 2012 was projected to increase to 21.4 mgd (23,968 afy) in 2050; however, according to the 2019 Addendum, based on updates to the city’s growth plan, the updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), comparatively lower than the previous prediction in the PEIR. Therefore, the projected water demands under the Master Plan Updates, in which the Projects were previously considered, would be less than analyzed in 2012 and the impact would be less than significant. The changes to specific details of the Projects would not change the city’s water demand or supply as provided in the 2019 Addendum. Sept 20, 2023 Item #2 Page 162 of 256 c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? As provided above, no capacity increases would result under the Projects that would otherwise require an increase in treatment capacity at the Encina Wastewater Treatment Control Facility. No new impact would result. d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? As discussed in the PEIR (Section 4.8, Hazards and Hazardous Materials) and the 2019 Addendum, all demolition debris and construction waste associated with construction of CIP projects under the Master Plans would be properly handled and disposed of, in accordance with federal, state and local laws and regulations related to solid and hazardous waste. Moreover, the long-term operations of the proposed Projects are water infrastructure and would not generate solid waste that would significantly impact the permitted capacity of area landfills. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? See item d). This impact would be less than significant. XX. Wildfire Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? If located in or near state responsibility areas or lands classified as very high fire hazard severity zones, would the project: a) Substantially impair an adopted emergency response plan or emergency evacuation plan? Yes No No No Sept 20, 2023 Item #2 Page 163 of 256 Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? Yes No No No c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? Yes No No No d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? Yes No No No a) Substantially impair an adopted emergency response plan or emergency evacuation plan? The PEIR (Section 4.8) and 2019 Addendum included analysis of wildfire hazards and impacts to emergency response. As provided, the service areas include mostly urbanized land; however, portions of the city service areas are located in areas classified as Very High Fire Hazard Severity Zones (CAL FIRE 2009). The Maerkle valve site (W-9) is located in a Very High Fire Hazard Severity Zone. As provided in the PEIR and 2019 Addendum, construction and design of all CIP projects would comply with the Uniform Fire Code (Title 24 Code of Federal Regulations, Part 9), which requires installation of sprinkler systems, fire-resistant building materials, standard roadway access widths, and other features to ensure that all above-ground structures are constructed with all reasonable fire safety features. Additionally, the city has committed to the multiple design features to minimize impacts related to wildfire: • Fire safety information will be disseminated to construction crews during regular safety meetings. Fire management techniques will be applied during project construction as deemed necessary by the lead agency and depending on-site vegetation and vegetation of surrounding areas. • A brush management plan will be incorporated during project construction by the city, CMWD, or a contractor, as necessary. Construction within areas of dense foliage during dry conditions will be avoided, when feasible. Sept 20, 2023 Item #2 Page 164 of 256 • In cases where avoidance is not feasible, necessary brush fire prevention and management practices will be incorporated. Specifics of the brush management program will be determined as site plans for the project are finalized. As provided in issue IX (f), the city has committed to preparing a traffic control plan for applicable CIP projects. Implementation of a traffic control plan is identified as a project design feature in the MMRP. Preparation of a brush management plan and dissemination of fire safety information to construction crews are also included as project design features in the MMRP, and would further minimize wildfire hazards for individual projects. In this context, the Projects would not substantially impair an adopted emergency response plan or emergency evacuation plan and the impact would be less than significant. The improvements proposed by the Projects are not of a substantially different character than the activities proposed under the PEIR and 2019 Addendum. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? See response a). The Projects would be constructed within existing urbanized areas to serve existing and approved development. The physical improvements proposed by the Projects would not exacerbate existing wildfire risks that could otherwise expose existing populations to pollutant concentrations from a wildfire. The Projects would result in a less than significant impact. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? The Projects would primarily be constructed in existing and future dedicated public rights of way and on city-owned properties and do not include any new electrical connections in high fire hazard zones. Preparation of a brush management plan and dissemination of fire safety information to construction crews are included as project design features in the MMRP, and would minimize wildfire hazards for individual projects. The physical improvements proposed under the Projects would serve existing development and would not exacerbate existing fire risks that could result in temporary or ongoing impacts to the environment. This is considered a less than significant impact. d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? See responses a) and b). The Projects would not exacerbate existing wildfire hazards that could otherwise result in downslope or downstream flooding or landslides, as a result of runoff, post-fire instability, or drainage changes. The Projects would be required to comply individually with the city’s engineering standards along with Carlsbad’s grading requirements, which would minimize any hazards related to landslides Compliance with existing regulations would minimize impacts to less than significant. Sept 20, 2023 Item #2 Page 165 of 256 XXI. Mandatory Findings of Significance Was Impact Analyzed in Prior Environmental Document(s)? Does Project Involve New Significant Impacts or Substantially More Severe Impacts? Any New Circumstances Involving New Significant Impacts or Substantially More Severe Impacts? Any New Information Requiring New Analysis or Verification? a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Yes No No No b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of past, present, and probable future projects)? Yes No No No c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Yes No No No a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? Sections 4.3 and 4.4 of the PEIR included consideration of potential cumulative impacts to biological and cultural resources. The 2019 Addendum identified less than significant impacts and did not contribute to more significant impacts than those identified in the PEIR. With the inclusion of the mitigation measures identified in the MMRP, the Projects would result in less than significant impacts. The physical improvements proposed under the Projects are not of a substantially different character than those certified in the PEIR. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new Sept 20, 2023 Item #2 Page 166 of 256 significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of past, present, and probable future projects)? Chapter 4 of the PEIR includes a consideration of potential cumulative impacts for each of the environmental resource topics considered. As provided in the 2019 Addendum, the city’s water demand in 2012 was projected to increase to 21.4 mgd (23,968 afy) at buildout; however, based on updates to the city’s growth plan, the updated projected potable water demand at buildout is 18.5 mgd (20,720 afy), comparatively lower than the previous predictions. Therefore, the projected water demands under the proposed Projects would be less than analyzed in 2012. Given that the activities proposed under the Projects have not substantially changed since the certification of the PEIR, the impact continues to be less than significant following application of the required mitigation. The analysis included in the PEIR and 2019 Addendum conservatively addresses the potential impacts of the Projects, since complete construction details were unknown. No substantial new information has been presented that shows the Projects would result in more significant impacts than those originally analyzed in the PEIR or 2019 Addendum. No new significant impacts were identified as part of this analysis. As a result, the conclusions identified in the PEIR and 2019 Addendum remain accurate and applicable to the proposed Projects. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Section 5.3 and 5.4 of the PEIR address the Master Plans’ potential to result in growth inducement and significant and unavoidable impacts, respectively. Given that the Projects would involve the ongoing management, replacement, and upgrade of the city’s water, sanitary sewer, and recycled water infrastructure, no substantial adverse effects on human beings, either directly or indirectly, would result. This impact is considered less than significant. Sept 20, 2023 Item #2 Page 167 of 256 5.0 Applicable Project-specific Mitigation Measures The following mitigation measures from the certified 2012 PEIR MMRP and 2019 Addendum MMRP would be applicable to the impacts associated with the Projects. The City’s updated 2017 Tribal, Cultural, and Paleontological Resources Guidelines were incorporated into MMRP for the 2019 Addendum to reflect updates to treatment of tribal, cultural, and paleontological resources. No new significant impacts or increased severity in impacts that were not analyzed in the PEIR or 2019 Addendum have been identified; therefore, no additional new Project-specific mitigation is required. As identified in the associated environmental analysis sections above, the mitigation measures are applicable to specific components of the Projects. The biological and cultural mitigation measures identified below would only be applicable to the Maerkle valve site. Based on tribal outreach conducted by CMWD, monitoring at the Maerkle site would be limited to spot checks during vault excavation. While implementation of BMPs and other project design features identified in the previous MMRPs would be required at the El Fuerte site, no specific mitigation measures would be required. 5.1 Biological Resources Bio-1A Project-Level Biological Resource Surveys. During the design phase and prior to the construction of applicable CIP projects, the city and CMWD shall retain a qualified biologist to conduct project-level biological surveys. The surveys shall verify whether the project would occur on or in the immediate vicinity of natural habitat and habitat suitable for special status species. The surveys shall also identify if the project could result in direct or indirect impacts to natural habitat and special status species. The survey results shall be submitted to the city and CMWD to determine the need for further surveys and project- level analyses for subsequent CEQA documentation and the issuance of any discretionary actions or permits for the project. If the Quarry Creek Master Plan project covering CIP projects N-9, 55, and ES7 is ultimately approved and developed, the city and CMWD shall implement the specific mitigation requirements of the Quarry Creek Master Plan EIR (EIR 11-02) accordingly. Bio-1D Avoidance of Nesting Birds and Raptors. To prevent direct impacts to nesting birds, including raptors, protected under the federal MBTA and CDFG Code, the city and CMWD shall enforce the following: Prior to removal or damage of any active nests or any tree pruning or removal operations during the prime nesting seasons, that being from March 15 to May 30, a certified biologist shall survey the trees to determine if there are any active nests within 500 feet of the area of tree removal or pruning. If any active nests are located within 500 feet, no tree pruning or removal operations can occur until the nests are vacated or until the end of the prime breeding season, whichever occurs later. In addition, prior to any tree removal or pruning operations proposed outside of the prime nesting season but within the period of January 15 to September 15, a confirmation is required from a certified biologist that no disturbance to active nests or nesting activities would occur. Documentation from a certified biologist consistent with these requirements shall be submitted to the City Planner for review and approval. A note to this effect shall be placed on the construction plans. Sept 20, 2023 Item #2 Page 168 of 256 Bio-1E Pre-Construction Biological Resource Surveys. Prior to construction of CIP projects or portions of projects that will occur within disturbed or developed land, but will be sited immediately adjacent to an undeveloped open space area (i.e., an area supporting naturalized habitat, sensitive habitat, and/or habitat potentially suitable for special status species), the city and CMWD shall retain a qualified biologist to perform a pre-construction survey to verify existing biological resources adjacent to the project construction areas. The city and CMWD shall provide the biologist with a copy of the CIP project plans that clearly depict the construction work limits, including construction staging and storage areas, in order to determine which specific portion(s) of the project will require inspection of adjacent open space areas during the pre-construction survey. At minimum, the biologist shall perform a visual inspection of the adjacent open space area in order to characterize the existing habitat types and determine the likelihood for special status species to occur, including the coastal California gnatcatcher, migratory songbirds, and other bird species with the potential to breed in the area. The pre-construction survey results shall be submitted to the city and CMWD prior to construction in order to verify the need for the additional construction measures proposed within Bio-1F through Bio-1I below. Bio-1F Orange Construction Fencing. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the city and CMWD shall retain a qualified biologist to supervise the installation of temporary orange construction fencing, which clearly delineates the edge of the approved limits of grading and clearing, and the edges of environmentally sensitive areas that occur beyond the approved limits. This fencing shall be installed prior to construction and maintained for the duration of construction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified. Temporary orange fencing shall be removed upon completion of construction of the project. Implementation of this measure shall be verified by the city prior to and concurrent with construction. Bio-1G Construction-Related Noise. Construction noise created during the general breeding season (January 15 to September 15) that could affect the breeding of the coastal California gnatcatcher, migratory songbirds, and other bird species associated with adjacent undeveloped areas shall be avoided. No loud construction noise (exceeding 60 dBA hourly average, adjusted for ambient noise levels, at the nesting site) may take place within 500 feet of active nesting sites during the general breeding season (January 15 through September 15). If it is confirmed through the implementation of mitigation measure Bio- 1E that the CIP project could result in construction-related noise impacts to breeding birds during the general breeding season, the city and CMWD shall retain a qualified biologist to monitor the construction operations. The biological monitor shall be present to monitor construction activities that occur adjacent to the undeveloped open space area potentially supporting breeding birds. The monitor shall verify that construction noise levels do not exceed 60 dBA hourly average and shall have the ability to halt construction work, if necessary, and confer with the city, USFWS, and CDFG to ensure the proper implementation of additional Sept 20, 2023 Item #2 Page 169 of 256 protection measures during construction. The biologist shall report any violation to the USFWS and/or CDFG within 24 hours of its occurrence. Bio-1H Construction Staging Areas. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the city and CMWD shall design final CIP project construction staging areas such that no staging areas shall be located within sensitive habitat areas. The construction contractor shall receive approval by the City Planning & Engineering Divisions prior to mobilization and staging of equipment outside of the project boundaries. Bio-1I Contractor Training. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the city and CMWD shall retain a qualified biologist to attend pre-construction meetings to inform construction crews of the sensitive resources and associated avoidance and/or minimization requirements. Bio-2A Habitat Compensation for Projects within the City of Carlsbad. If it is demonstrated through the implementation of mitigation measure Bio-1A that applicable CIP projects could directly impact sensitive natural communities, including Habitat Groups A, B, C, D, E, and F specified in Table 11 and Section D.6 of the City of Carlsbad HMP, the city and CMWD shall implement the following: 1. Mitigation for unavoidable impacts to Habitat Groups A, B, C, D, E, and F shall be provided according to the ratios specified below and consistent with Table 11 and Section D.6 of the City of Carlsbad HMP: HMP Habitat Mitigation Ratios Habitat Group and Type Mitigation Ratio A.

Disturbed lands, eucalyptus woodland, agriculture 0.01:1 2. Impacts to Habitat Groups D, E, and F shall be mitigated at the Lake Calavera Mitigation Bank in accordance with Appendix B of the City of Carlsbad HMP for covered city projects that are eligible to mitigate impacts at the Lake Calavera Mitigation Bank. Sept 20, 2023 Item #2 Page 170 of 256 3. Impacts to Habitat Groups A, B, and C shall be to the maximum extent practicable through project-level siting during CIP project design and trenchless pipeline installation methods (e.g., jack and bore, horizontal directional drilling) during CIP project construction. 4. Unavoidable impacts to Habitat Groups A, B, and C shall be mitigated in-kind through implementation of any one or combination of the following measures, as approved and/or amended by the USFWS, USACE, RWQCB, and/or CDFG, if applicable: a. On site as creation of new habitat within avoided and preserved areas at the CIP project site; b. On site as restoration of existing habitat within temporary impact areas and/or avoided and preserved areas at the CIP project site; c. On site as enhancement of existing habitat within avoided and preserved areas at the CIP project site; d. Off site as purchase of habitat credits within an approved mitigation bank(s) (e.g., Carlsbad Oaks Conservation Bank, North County Habitat Bank); e. Off site as habitat preservation, creation, restoration, and/or enhancement within other properties or approved mitigation programs available at the time of grading; or f. A combination of the above. g. In the coastal zone, impacts to Habitat Groups A, B, and C shall be mitigated in accordance with the ratios described in Section D.7 of the HMP and shall include at a minimum a 1:1 creation (or substantial restoration when allowed) component to ensure no net loss of habitat. The remainder of the mitigation obligation may be satisfied pursuant to the provisions of the HMP. The proposed mitigation for impacts to Habitat Grounds A, B, and C in the coastal zone is subject to review by the California Coastal Commission. 5. On- or off-site creation, restoration, and/or enhancement mitigation for habitat groups A, B, and C shall consist of the following: a. For Habitat Group A types, including riparian and wetland sensitive natural communities (e.g., riparian forest, riparian woodland, riparian scrub, disturbed wetlands, coast live oak woodland), the city or CMWD shall prepare a Riparian/Wetland Habitat Restoration Plan detailing the specific riparian/wetland creation, restoration, and/or enhancement measures to be implemented as project mitigation. The Riparian/Wetland Habitat Restoration Plan shall be approved by the USFWS, USACE, RWQCB, and/or CDFG, as appropriate, prior to vegetation clearing, grading, and/or construction activities. Sept 20, 2023 Item #2 Page 171 of 256 b. For Habitat Group B types, including upland sensitive natural communities (e.g., maritime succulent scrub, southern maritime chaparral, native grassland), the city or CMWD shall prepare an Upland Habitat Restoration Plan detailing the specific upland habitat creation, restoration, and/or enhancement measures to be implemented as project mitigation. The Upland Habitat Restoration Plan shall be approved by the USFWS and CDFG prior to vegetation clearing, grading, and/or construction activities. c. For Habitat Group C types (occupied Coastal Sage Scrub), the city or CMWD shall prepare a Coastal Sage Scrub Habitat Restoration Plan detailing the specific coastal sage scrub habitat creation, restoration, and/or enhancement measures to be implemented as project mitigation. The Coastal Sage Scrub Habitat Restoration Plan shall be approved by the USFWS and CDFG prior to vegetation clearing, grading, and/or construction activities. d. The restoration plans for Habitat Groups A, B, and C shall include a five-year maintenance and monitoring program with a requirement to meet city and Wildlife Agencies approved success criteria. 6. Any upland or riparian/wetland habitat impacts that occur beyond the approved work limits of any CIP project shall be mitigated at a higher ratio to be negotiated with the USFWS, USACE, RWQCB, and/or CDFG. 7. If the Quarry Creek Master Plan project covering CIP projects N-9, 55, and ES7 is ultimately approved and developed, the city and CMWD shall implement the specific mitigation requirements of the Quarry Creek Master Plan EIR (EIR 11-02) accordingly. 5.2 Cultural Resources Cul-1 Cultural Resources Investigation. For the CIP projects proposed in close proximity to a known cultural resource or projects that would result in ground-disturbing activities in a previously undisturbed area, a project-level cultural resources investigation shall be conducted by a qualified cultural resource professional as defined in the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017) (2017 Guidelines) The cultural resources investigation shall include: 1. A CIP project site-specific review of the records search data at the South Coastal Information Center shall be conducted to determine if the CIP project site has been subjected to a professional survey. a. If a current cultural resources report addressing potential impacts on cultural resources is available, the city or CMWD shall implement the mitigation measures provided within the report. In the event that a current and valid report is not available, or if the entirety of the CIP project site has not been professionally surveyed, then an updated records search shall be performed. Sept 20, 2023 Item #2 Page 172 of 256 b. In accordance with the 2017 Guidelines, the city or CMWD shall contact the NAHC and local tribal governments for input on the project in order to identify any additional Native American resources that may not be included in the records search. 2. For those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. Updates for all resources encountered during the Phase I survey shall be recorded using Department of Parks and Recreation (DPR) 523 forms in accordance with all applicable regulations. Resources shall be evaluated for significance and eligibility for inclusion in all applicable historic registers using methods such as, but not limited to, subsurface testing and/or archival research. Any subsurface testing would be monitored by an appropriate Native American representative. 3. In the event that such resources are found to be historical resources pursuant to CEQA, potential adverse impacts must be analyzed as stated in PRC Sections 21084.1 and 21083.2(l). Suitable mitigation for significant effects on archaeological resources are outlined in Section 15126.4(b)(3) as well as the 2017 Guidelines. The city or CMWD shall be responsible for implementing the methods for eliminating or substantially reducing impacts on resources as recommended by the archeologist and in consultation with the Native American Tribe. Such methods could include, but are not limited to: a. Planning construction to avoid archaeological sites; b. Incorporation of sites within parks, greenspace, or other open space; c. Capping or covering a site with a layer of soil before building on the site; d. Deeding the site into a permanent conservation easement; e. Excavation (Data Recovery) of archaeological resources; and/or f. Construction monitoring by a qualified professional and appropriate Native American monitors as identified through consultation with the NAHC or Native American Tribe. The monitor(s) shall be present at all pre- construction meetings. 4. If, as a result of Cul 1 -3, it is determined that a CIP project site requires monitoring by a Native American Tribe, then the city or CMWD shall enter into a Pre-Excavation Agreement or Cultural Resource Treatment and Monitoring Agreement with the appropriate Native American Tribe prior to the commencement of earth disturbing activities and consistent with the 2017 Guidelines. The results of the cultural resources investigation shall be complied into a technical report or memorandum and submitted to the city or CMWD and the South Coastal Information Center.

(HELIX) for the proposed Carlsbad Municipal Water District (District) Maerkle Motorized Valves Project (project), located in the City of Carlsbad (City), San Diego County, California. Activities would include the installation of a new underground vault approximately 50 feet southwest of the existing vault, and the installation of associated piping. The purpose of this report is to document the existing biological conditions within the project site plus a 500-foot buffer (study area), which encompasses approximately 20.8 acres, and provide an analysis of potential impacts on sensitive biological resources with respect to local, state, and federal policy. This report provides the biological resources technical documentation necessary for review under California Environmental Quality Act (CEQA) by the District. PROJECT LOCATION The project site is located south of State Route 78 and north of Agua Hedionda Creek, within an unsectioned portion of the Agua Hedionda land grant, in Township 12 South, Range 4 West on the San Luis Rey U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle, north of Los Monos Canyon (Figures 1 and 2, Regional Location and USGS Topography, respectively). The project site is located north of Sunny Creek Road, adjacent to Squires Reservoir (Figure 3, Aerial Photograph). The study area does not overlap with any U.S. Fish and Wildlife Service (USFWS)-designated critical habitat (USFWS 2022a). PROJECT DESCRIPTION The project involves the replacement of two existing isolation valves and piping with new motorized valves and piping, which would automate water system operations at this location (Figure 4, Site Plan). The existing 24-inch and 42-inch valves divert water into the 10-million-gallon tank and the 200-million- Sept 20, 2023 Item #2 Page 178 of 256 gallon reservoir. The new valves are to be installed in a new underground vault at the base of the slope to make it easier to access the valves and improve worker safety. Specific staging areas have not yet been identified; staging areas would be located within developed locations. In addition, project design features for the avoidance of sensitive biological resources have been incorporated as fundamental components of the project. Facility improvements at the Maerkle Reservoir are included as CIP project W-9 (50091) in the August 2019 Addendum to the Program Environmental Impact Report (PEIR) for the 2012 CMWD Water Master Plans Update (SCH No. 2012021006; 2019 Addendum), as well as the PEIR itself as Project R7. The PEIR found that Project R7 would not have biological impacts because it involves repair, maintenance, replacements, upsize, improvements, and/or other minor modifications to existing facilities, and is located entirely within, and surrounded by, existing disturbed and/or developed land. However, the improvements were described in the PEIR as replacing joint sealing in the 10 MG tank and adding security lights and cameras along the access road, gates, and site. Excavation and/or ground disturbance was not assumed in the PEIR but is required for the project. CIP projects were analyzed in the City of Carlsbad Sewer Master Plan and Carlsbad Municipal Water District Water and Recycled Water Master Plans Update Program Environmental Impact Report (PEIR) & Addendum (EIR 12-01; SCH No. 2012021006). This project is included in the CIP as project W-9, which was included in the 2019 Addendum to the PEIR. METHODS Project evaluation included a review of existing information and field surveys. This section discusses the methods used to evaluate the biological resources present within the study area. Literature Review Prior to conducting biological field surveys, HELIX performed a thorough review of relevant maps, databases, and literature pertaining to the biological resources known to occur within the study area. Recent and historical aerial imagery, USGS topographic maps, soils maps (Natural Resource Conservation Service [NRCS] 2022), and other maps of the study area and vicinity were acquired and reviewed to obtain updated information on the natural environmental setting. In addition, HELIX conducted a query of special-status species and habitats databases, including the USFWS species records (USFWS 2022b), California Department of Fish and Wildlife (CDFW) California Natural Diversity Database (CNDDB; CDFW 2022), Calflora database (Calflora 2022), SanBIOS and California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants (CNPS 2022). The USFWS’ National Wetlands Inventory (NWI) was also reviewed (USFWS 2022c). Any recorded locations of species, habitat types, wetlands, and other resources were mapped and overlain onto aerial imagery using Geographic Information Systems (GIS). Biological Surveys General Biological Survey A general biological survey of the study area was conducted by HELIX biologist Mandy Mathews on March 10, 2022. Vegetation was mapped on a 1"=200' scale aerial of the site. A minimum mapping unit Sept 20, 2023 Item #2 Page 179 of 256 size of 0.1 acre was used when mapping upland habitat. The study area was surveyed on foot and with the aid of binoculars. Plant and animal species observed or otherwise detected were recorded in field notebooks (Attachments A and B). Habitat suitability and potential for occurrence were assessed for special-status species known to the region (Attachments C and D). Animal identifications were made in the field by direct, visual observation or indirectly by detection of calls, burrows, tracks, or scat. Plant identifications were made in the field or in the lab through comparison with photographs. Representative site photos are located in Attachment E. Survey Limitations Noted animal species were identified by direct observation, vocalizations, or the observance of scat, tracks, or other signs. However, the lists of species identified are not necessarily comprehensive accounts of all species that utilize the project site, as species that are nocturnal, secretive, or seasonally restricted may not have been observed. Those species that are special-status and have the potential to occur in the project site are still addressed in this report. Nomenclature Nomenclature for this report is taken from Holland (1986) and Oberbauer (2008) for vegetation communities; Baldwin et al. (2012) for plants; North American Butterfly Association (2021) for butterflies; Society for the Study of Amphibians and Reptiles (2022) for reptiles and amphibians; American Ornithological Society (2021) for birds; and Bradley et al. (2014) for mammals. Plant species status is from the CNPS Rare Plant Inventory (2022a) and CDFW (2022b). Animal species status is from the CDFW (2022c). EXISTING CONDITIONS General Land Uses The study area is generally located within the northern portion of the City of Carlsbad, which is a coastal area situated in northern San Diego County. The general area is predominantly characterized by residential development to the northwest, agricultural land to the west, and undeveloped land to the north and south (Figure 3). Land uses that characterize the project site and surrounding area include residential development, agriculture, and water conveyance infrastructure. Topography and Soils Elevations in the study area range from approximately 400 to 520 feet above mean sea level. The project site area is generally flat, with the study area sloping down towards the southwest. One soil type has been mapped in the study area (Figure 5, Soils): Cieneba coarse sandy loam, 5 to 15 percent slopes, eroded. Vegetation Communities Four vegetation communities/habitat types occur in the study area, as presented in Table 1, Vegetation Communities/Habitat Types, and shown on Figure 6, Vegetation and Sensitive Resources. The numeric Sept 20, 2023 Item #2 Page 180 of 256 codes in parentheses following each community/habitat type name are taken from the Holland (Holland 1986) and Oberbauer (2008) classification systems. Table 1 VEGETATION COMMUNITIES/HABITAT TYPES Vegetation Communities/Habitat Types Study Area (acres)1 Diegan Coastal Sage Scrub (including disturbed and restored; 32500) 8.39 Eucalyptus Woodland (79100) 0.37 Disturbed Habitat (11300) 6.33 Urban/Developed (12000) 5.70 TOTAL 20.79 1 The study area extends 500 feet from the proposed project. Diegan Coastal Sage Scrub (including Restored and Disturbed) Coastal sage scrub is one of the two major shrub types that occur in southern California, occupying xeric sites characterized by shallow soils (the other is chaparral). Four distinct coastal sage scrub geographical associations (northern, central, Venturan, and Diegan) are recognized along the California coast. Diegan coastal sage scrub typically consists of low-growing, soft woody sub-shrubs, up to one meter in height, that bloom in the winter and early spring. The community commonly occurs on low moisture availability sites characterized by steep xeric slopes or clay-rich soils that have high water retention. Diegan coastal sage scrub occurs to the west and south of the project site, outside of proposed impacts but within the study area. Dominants of this community observed on-site consist primarily of California buckwheat (Eriogonum fasciculatum), California sagebrush (Artemisia californica), and laurel sumac (Malosma laurina). Restored Diegan coastal sage scrub occurs on the slopes surrounding the 10-million-gallon tank and mainly consists of San Diego sunflower (Bahiopsis laciniata), California sagebrush, and California buckwheat. Disturbed Diegan coastal sage scrub occurs west and north of the project site and consists of California sagebrush, California buckwheat, tocalote (Centaurea melitensis), short-pod mustard (Hirschfeldia incana), and crown daisy (Glebionis coronaria). Eucalyptus Woodland Eucalyptus woodland is dominated by eucalyptus (Eucalyptus sp.), an introduced species that has often been planted purposely for wind-blocking, ornamental, and hardwood production purposes. Most groves are monotypic, with the most common species being either the blue gum (Eucalyptus globulus) or red gum (E. camaldulensis ssp. obtusa). The understory within well-established groves is usually very sparse due to the closed canopy and allelopathic nature of the abundant leaf and bark litter. If sufficient moisture is available, this species becomes naturalized and is able to reproduce and expand its range. The sparse understory offers only limited wildlife habitat; however, as a wildlife habitat, these woodlands provide excellent nesting sites for a variety of raptors, including red-shouldered hawks (Buteo lineatus). During winter migrations, a large variety of warblers may be found feeding on the insects that are attracted to the eucalyptus flowers. Eucalyptus trees with active raptor nests are considered sensitive. Within the study area, a small stand of eucalyptus woodland occurs east of the project site and is dominated by blue gum and spider gum (Eucalyptus conferruminate). Sept 20, 2023 Item #2 Page 181 of 256 Disturbed Habitat Disturbed habitat includes land cleared of vegetation (e.g., dirt roads), land containing a preponderance of non-native plant species, such as ornamentals or ruderal exotic species that take advantage of disturbance (previously cleared or abandoned landscaping), or land showing signs of past or present animal usage that removes any capability of providing viable habitat. Disturbed habitat consists of bare ground with scattered annual non-native species, including mustard (Brassica ssp.), Russian thistle (Salsola tragus), and filaree (Erodium cicutarium). Disturbed habitat occurs atop the 10-million-gallon tank, to the north and west of the 10-million-gallon tank, and in smaller patches along paved roadways. The dominant species within these areas are short-pod mustard, filaree, and crown daisy. Urban/Developed Urban/developed land includes areas that have been constructed upon or otherwise covered with a permanent, unnatural surface and may include, for example, structures, pavement, irrigated landscaping, or hardscape to the extent that no natural land is evident. These areas no longer support native or naturalized vegetation. Developed portions of the study area consist of paved roads, residential developments, and access paths with compacted soil/gravel. Plants A total of 46 plant species were observed within the study area during the general biological survey, of which 22 (48 percent) are non-native species (Appendix A, Plant Species Observed). The predominance of non-native species is indicative of the high degree of disturbance as a result of historical and current uses of the study area. Animals A total of 32 animal species were observed/detected within the study area during the general biological survey and focused species surveys: six invertebrates, one reptile, 22 bird species, and three mammals (Appendix B; Animal Species Observed or Detected). Sensitive Resources Sensitive Vegetation Communities/Habitats Sensitive vegetation communities/habitat types are defined as land that supports unique vegetation communities or the habitats of rare or endangered species or subspecies of animals or plants as defined by Section 15380 of the State CEQA Guidelines. The CDFW evaluates the rarity of natural communities using the NatureServe’s Heritage Methodology (Faber-Langendoen et al. 2012), in which communities are given a G (global) and S (State) rank based on their degree of imperilment (as measured by rarity, trends, and threats). Communities are assigned an overall rank of 1 through 5, with 1 being considered very rare and threatened and 5 being considered demonstrably secure. Communities with a Rarity Ranking of S1 (critically imperiled), S2 (imperiled), or S3 (vulnerable) are considered sensitive by the CDFW. Sept 20, 2023 Item #2 Page 182 of 256 Diegan coastal sage scrub (including disturbed) has a ranking of S3.1; therefore, it is considered a sensitive vegetation community (CDFW 2022b). Under the City’s HMP, Diegan coastal sage scrub, occupied by coastal California gnatcatcher, is classified as Group C, which requires maximum avoidance and on-site conservation as practical (Carlsbad 2022). Diegan coastal sage scrub that is unoccupied is classified as Group D, and disturbed habitat and eucalyptus woodland are classified as Group F. Urban/developed lands do not meet the definition of sensitive habitat under CEQA or the City’s HMP. Special Status Plant Species Special status plant species have been afforded special status and/or recognition by the USFWS and/or CDFW. They may also be included in the CNPS’ Inventory of Rare and Endangered Plants. Their status is often based on one or more of three distributional attributes: geographic range, habitat specificity, and/or population size. Sensitive species are those considered unusual or limited in that they are: (1) only found in the region; (2) a local representative of a species or association of species not otherwise found in the region; or (3) severely depleted within their ranges or within the region. No special status plant species were observed within the study area. Sensitive Plant Species with Potential to Occur Additional special-status plant species that were not observed but may have potential to occur within the study area are listed in Appendix C, Special Status Plant Species Observed or with Potential to Occur. No additional plant species have a high potential to occur based on geographic range, elevation range, and/or lack of suitable habitat in the study area. Special Status Animal Species Special status animal species include those that have been afforded special status and/or recognition by the USFWS and/or CDFW. In general, the principal reason an individual taxon (species or subspecies) is given such recognition is the documented or perceived decline or limitations of its population size or geographical extent and/or distribution, and in most cases, resulting from habitat loss. Two special-status animal species were observed within or adjacent to the study area during the 2022 project biological survey (Figure 6), coastal California gnatcatcher (Polioptila californica californica) and California horned lark (Eremophila alpestris actia). Coastal California gnatcatcher (Polioptila californica californica) Status: FT/SSC Distribution: In San Diego County, occurs throughout coastal lowlands Habitat(s): Coastal sage scrub Status on site: A pair of coastal California gnatcatchers was observed within Diegan coastal sage scrub approximately 320 feet southwest of the proposed project site. California horned lark (Eremophila alpestris actia) Status: --/WL Distribution: Observed year-round scattered throughout San Diego County Habitat(s): Coastal strand, arid grasslands, and sandy desert floors Status on site: Three California horned larks were observed within sparse disturbed habitat atop the 10- million-gallon tank, approximately 125 feet northeast of the proposed project site. Sept 20, 2023 Item #2 Page 183 of 256 Sensitive Animal Species with Potential to Occur Special status animal species that were not observed or otherwise detected but determined to have some potential to occur on-site are included in Appendix D, Special Status Animal Species Observed or with Potential to Occur. The species are grouped into invertebrates and vertebrates (amphibians, reptiles, birds, and mammals) and alphabetized by scientific name. One species analyzed has a high potential to occur: Belding’s orange-throated whiptail (Aspidoscelis hyperythrus beldingi). Orange-throated whiptail, a Watch List species, has been reported within disturbed habitat, as recent as 2017. No other species have a high potential to occur based on geographic range, elevation range, and/or lack of suitable habitat in the project site. Nesting Birds Trees and shrubs both within and adjacent to the project site could provide suitable nesting habitat for numerous bird species known to the region. Raptor Foraging One raptor species was observed during the general biological survey: red-tailed hawk (Buteo jamaicensis). Additionally, several other species have the potential to forage in the project vicinity. The project site itself does not provide raptor habitat due to the small footprint and lack of suitable areas to perch or nest. Extensive raptor foraging habitat occurs immediately adjacent to the project vicinity within undeveloped areas surrounding the project, as well as nesting habitat within tall trees or structures nearby. Wildlife Corridor/Core Wildlife Areas Wildlife corridors connect otherwise isolated pieces of habitat and allow movement or dispersal of plants and animals. Wildlife corridors can be local or regional in scale and may function in different ways depending on species and time of year. Wildlife corridors represent areas where wildlife movement is concentrated due to natural or manufactured constraints. Local corridors provide access to resources such as food, water, and shelter. Animals can use these corridors, such as hillsides and tributary drainages to main drainages, to travel among different habitats (i.e., riparian and upland habitats). Some animals require riparian habitat for breeding and upland habitat for burrowing. Regional corridors provide these functions and also link two or more large areas of open space. Regional corridors also provide avenues for wildlife dispersal, migration, and contact between otherwise distinct populations. The project is located within the Core 5 Focus Planning Area (FPA) of the Carlsbad Habitat Management Plan (HMP; Carlsbad 2004). The western portion of the study area is within Linkage C, which supports a mixture of agricultural fields and native habitat and connects Core 5 to Core 3 to the west. The project site occurs within a maintained area adjacent to residential development and roadways/public right-of- way (ROW). The project site is located in an existing disturbed area, which reduces its value as a wildlife corridor or core wildlife area, although it may function as a stopover site for migrating bird species. The Dawson-Los Monos Canyon Reserve, an existing Hardline Conservation Area south of Sunny Creek Road, provides protected natural habitat which is more likely to support local and regional wildlife movement and live-in habitat than the project site. No other identified linkages occur within or adjacent to the study area (South Coast Wildlands 2008). Sept 20, 2023 Item #2 Page 184 of 256 REGULATORY FRAMEWORK Biological resources in the project site are subject to regulatory review by federal, state, and local agencies. Under CEQA, impacts associated with a proposed project are assessed with regard to significance criteria determined by the CEQA Lead Agency (in this case, the District) pursuant to CEQA Guidelines. Biological resources-related laws and regulations that apply to the project analysis include the Federal Endangered Species Act (FESA), Migratory Bird Treaty Act (MBTA), CWA, CEQA, California Endangered Species Act (CESA), and CFG Code. Federal Federal Endangered Species Act Administered by the USFWS, the federal ESA provides the legal framework for the listing and protection of species (and their habitats) that are identified as being endangered or threatened with extinction. Actions that jeopardize endangered or threatened species and the habitats upon which they rely are considered take under the ESA. Section 9(a) of the ESA defines take as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to engage in any such conduct.” “Harm” and “harass” are further defined in federal regulations and case law to include actions that adversely impair or disrupt a listed species’ behavioral patterns. Sections 7 and 4(d) of the Federal ESA regulate actions that could jeopardize endangered or threatened species. Section 7, administered by the USFWS, describes a process of Federal interagency consultation for use when Federal actions may adversely affect listed species. A Section 7 Consultation (formal or informal) is required when there is a nexus between a listed species’ use of a site and if the project is funded (wholly or in part) by federal funding. A biological assessment is required for any major construction or maintenance activity, if it may affect listed species. Take can be authorized via a letter of Biological Opinion, issued by the USFWS, for non-marine related listed species issues. Identified by the USFWS, critical habitat is defined as areas of land that are considered necessary for endangered or threatened species to recover. The ultimate goal is to restore healthy populations of listed species within their native habitat so they can be removed from the list of threatened or endangered species. Once an area is designated as critical habitat pursuant to the federal ESA, all federal agencies must consult with the USFWS to ensure that any action they authorize, fund, or carry out is not likely to result in the destruction or adverse modification of the critical habitat. Migratory Bird Treaty Act All migratory bird species that are native to the United States or its territories are protected under the federal MBTA, as amended under the Migratory Bird Treaty Reform Act of 2004 (FR Doc. 05-5127). The MBTA is generally protective of migratory birds but does not actually stipulate the type of protection required. In common practice, the MBTA is used to place restrictions on the disturbance of active bird nests during the nesting season (generally February 1 to August 31). In addition, the USFWS commonly places restrictions on disturbances allowed near active raptor nests. Sept 20, 2023 Item #2 Page 185 of 256 State Regulations California Environmental Quality Act Primary environmental legislation in California is found in CEQA and its implementing guidelines (State CEQA Guidelines), which require that projects with potential adverse effects (i.e., impacts) on the environment undergo environmental review. Adverse environmental impacts are typically mitigated as a result of the environmental review process in accordance with existing laws and regulations. California Endangered Species Act The CESA established that it is state policy to conserve, protect, restore, and enhance state endangered species and their habitats. Under state law, plant and animal species may be formally designated rare, threatened, or endangered by official listing by the California Fish and Game Commission. The CESA authorizes that private entities may “take” plant or wildlife species listed as endangered or threatened under the FESA and CESA, pursuant to a federal Incidental Take Permit if the CDFW certifies that the incidental take is consistent with CESA (CFG Code Section 2080.1[a]). For state-only listed species, Section 2081 of CFG Code authorizes the CDFW to issue an Incidental Take Permit for state-listed threatened and endangered species if specific criteria are met. The Carlsbad HMP was prepared pursuant to Section 2081 of the CESA, and the City was issued an umbrella Section 2081 ITP from the CDFG authorizing take of multiple state listed species. Native Plant Protection Act Sections 1900–1913 of the CFG Code (Native Plant Protection Act; NPPA) direct the CDFW to carry out the state legislature’s intent to “…preserve, protect, and enhance endangered or rare native plants of this state.” The NPPA gives the California Fish and Game Commission the power to designate native plants as “endangered” or “rare” and protect endangered and rare plants from take. California Fish and Game Code The CFG Code provides specific protection and listing for several types of biological resources. Section 1600 of CFG Code requires a Streambed Alteration Agreement (SAA) for any activity that would alter the flow, change, or use any material from the bed, channel, or bank of any perennial, intermittent, or ephemeral river, stream, and/or lake. Typical activities that require an SAA include excavation or fill placed within a channel, vegetation clearing, structures for diversion of water, installation of culverts and bridge supports, cofferdams for construction dewatering, and bank reinforcement. Notification is required prior to any such activities. Pursuant to CFG Code Section 3503, it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by this code or any regulation made pursuant thereto. Raptors and owls and their active nests are protected by CFG Code Section 3503.5, which states that it is unlawful to take, possess, or destroy any birds of prey or to take, possess, or destroy the nest or eggs of any such bird unless authorized by the CDFW. Section 3513 states that it is unlawful to take or possess any migratory non-game bird as designated in the MBTA. These regulations could require that construction activities (particularly vegetation removal or construction near nests) be reduced or eliminated during critical phases of the nesting cycle unless surveys by a qualified biologist demonstrate that nests, eggs, or nesting birds will not be disturbed, subject to approval by CDFW and/or USFWS. Sept 20, 2023 Item #2 Page 186 of 256 California Natural Community Conservation Planning Act of 1991 The NCCP Act is designed to conserve habitat-based natural communities at the ecosystem scale while accommodating compatible land uses in coordination with CESA. CDFW is the principal state agency implementing the NCCP Program. The Act established a process to allow for comprehensive, long-term, regional, multi-species, and habitat-based planning in a manner that satisfies the requirements of the state and FESAs (through a companion regional habitat conservation plan). The NCCP program has provided the framework for innovative efforts by the state, local governments, and private interests, to plan for the protection of regional biodiversity and the ecosystems upon which they depend. NCCPs seek to ensure the long-term conservation of multiple species, while allowing for compatible and appropriate economic activity to proceed. The Carlsbad HMP was prepared as part of the Multiple Habitat Conservation Program (MHCP) subregional planning pursuant to the NCCP Act. Local Regulations Multiple Habitat Conservation Program The MHCP is a comprehensive, multiple jurisdictional planning program, designed to develop an ecosystem preserve in northwestern San Diego County. Implementation of the regional preserve system is intended to protect viable populations of key sensitive plant and animal species and their habitats, while accommodating continued economic development and quality of life for residents of the North County region. The MHCP is one of several large multiple jurisdictional habitat planning efforts in San Diego County, each of which constitutes a subregional plan under the NCCP Act of 1991. The MHCP includes seven incorporated cities in northwestern San Diego County: Carlsbad, Encinitas, Escondido, Oceanside, San Marcos, Solana Beach, and Vista. These jurisdictions will implement their respective portions of the MHCP through citywide “subarea” plans, which describe the specific implementing mechanisms each city will institute for the MHCP. The goal of the MHCP is to conserve approximately 19,000 acres of habitat, of which roughly 8,800 acres (46 percent) are already in public ownership, and contribute toward the habitat preserve system for the protection of more than 80 rare, threatened, or endangered species. The Carlsbad HMP is the only approved and adopted Subarea Plan under the MHCP. Carlsbad Habitat Management Plan (HMP) The City approved the Carlsbad HMP in 2004 and adopted ordinance regulations in Chapter 21.210 of the Carlsbad Municipal Code as a condition of receiving approval from the CCC, an ITP from the USFWS pursuant to Section 10(a)(1)(B) of the FESA, and incidental take authorization from the CDFG pursuant to the CESA and Section 2835 of the CFG Code. Since its adoption, the Carlsbad HMP has allowed for citywide permits and the authorization for the incidental take of sensitive species in conjunction with private development projects, public projects, and other activities consistent with the HMP. The Carlsbad HMP has been successful in contributing toward the conservation of local habitats and recovery of regionally sensitive plant and animal species within Carlsbad. The HMP designates approximately 6,500 acres of the open space lands in Carlsbad for preservation based on its value as habitat for endangered animals and rare, unique, or sensitive plant species. The plan identifies how the City of Carlsbad can protect and maintain these lands while still allowing additional public and private development consistent with the General Plan and the Growth Management Plan. The purpose and intent of Chapter 21.210 of the Carlsbad Municipal Code in implementing the Carlsbad HMP are summarized below. Sept 20, 2023 Item #2 Page 187 of 256 Habitat Preservation and Management Requirements Chapter 21.210 of the Carlsbad Municipal Code requires all development to comply with the Carlsbad HMP as well as the implementing agreement, permit conditions, the MHCP, the NCCP and 10(a)(1)(B) permit conditions, and the requirements contained in Habitat Preservation and Management Requirements Ordinance. No grading is allowed to occur for projects in Carlsbad until all the processing and permitting requirements of this chapter are fulfilled. The purpose and intent of the Habitat Preservation and Management Requirements Ordinance are to: • Implement the goals and objectives of the land use and the open space/conservation elements of the Carlsbad General Plan; • Implement the Carlsbad HMP, the implementing agreement and conditions, the North County MHCP, the California NCCP and 10(a)(1)(B) permit conditions; • Preserve the diversity of natural habitats in Carlsbad and protect the rare and unique biological resources located within those habitats; • Assure that all development projects comply with the habitat preservation and conservation standards contained in the Carlsbad HMP; • Provide a process for permitting limited, incidental impacts to occur to natural habitat areas and the species located therein; and • Provide a process for allowing minor amendments from the habitat preservation and conservation standards under limited, specified circumstances. An HMP Permit is required to be obtained from the City for any development project which directly or indirectly impacts natural habitat within the Carlsbad HMP boundaries. Habitat conservation planning is processed as a Consistency Finding and requires concurrence from the USFWS and CDFW. Zone Level Recommendations The project is situated within Local Facilities Management Zone 15 (Zone 15) of the Carlsbad HMP planning area. The HMP Conservation Goals for Zone 15 are to establish, enhance, and maintain a viable habitat linkage across Linkage Area C to ensure connectivity for gnatcatchers and other HMP species between Core Areas 3 and 5 and to conserve the majority of sensitive habitats in or contiguous with biological core and linkage areas, including no net loss of wetland habitats and coastal sage scrub within Core Area 3 and Linkage Area C. The Standards Area within Zone 15 occurs within Linkage Area C, to the west of the project site, and does not apply to the project site. SIGNIFICANCE OF PROJECT IMPACTS AND PROPOSED MITIGATION This section describes potential direct and indirect impacts associated with the proposed project. Direct impacts immediately alter the affected biological resources such that those resources are eliminated temporarily or permanently. Proposed project activities would result in temporary impacts to Diegan coastal sage scrub, disturbed habitat, and urban/developed lands. Permanent impacts include an approximately 120-square foot vault. Sept 20, 2023 Item #2 Page 188 of 256 Criteria for Determining Impact Significance The significance of impacts to biological resources present, or those with potential to occur, was determined based on the sensitivity of the resource and the extent of the anticipated impacts. For certain highly sensitive resources (e.g., a federally listed species), any impact would be significant. Conversely, other resources that are of low sensitivity (e.g., species with a large, locally stable population in the County but declining elsewhere) could sustain some impact with a less than significant effect. According to Appendix F of the CEQA Guidelines, project impacts to biological resources would be considered significant if they would: (a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by CDFW or USFWS. (b) Have a substantial adverse effect on any riparian habitat or sensitive natural community identified by local or regional plans, policies, regulations, or by CDFW or USFWS. (c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the CWA (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling hydrological interruption, or other means. (d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species, or with an established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites. (e) Conflict with local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. (f) Conflict with provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan. Issue 1: Special-Status Species Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the CDFW or USFWS? Impact Analysis Special-Status Plant Species No federally or state listed species would be impacted by project activities. No sensitive plant species were mapped within the study area, and no other special-status or listed species has a high potential to occur within the project area. Sept 20, 2023 Item #2 Page 189 of 256 No special-status plant species are anticipated to be affected by project activities, as the project impact areas are restricted to an area of disturbed habitat and a small area of previously restored Diegan coastal sage scrub. As no direct impacts to sensitive plants are anticipated, no mitigation is required. Special-Status Animal Species If avoidance measures are not in place, the project could result in significant direct and/or indirect impacts to several special-status bird species during construction, as detailed further below. The coastal California gnatcatcher was observed within the study area, within 500 feet of the project site, and suitable habitat for this species occurs on-site. If avoidance measures are not in place, then project construction could result in potential significant noise-related indirect impacts on the coastal California gnatcatcher, if breeding individuals become displaced from their nests and fail to breed. The project incorporates PEIR mitigation measures Bio-1D through Bio-1I to ensure that potential direct or indirect impacts on the coastal California gnatcatcher are avoided. One other special-status bird was also detected within the study area: California horned lark, a State Watch List species. If avoidance measures are not in place, then project construction could result in potential significant direct impact and noise-related indirect impacts to special-status bird species, including tree-nesting raptors. The project is required to comply with the regulations and guidelines of the Carlsbad HMP, MBTA, and CFG Code. As such, the project must ensure no direct or indirect impacts to nesting birds and tree-nesting raptors. The project incorporates PEIR mitigation measures Bio-1D through Bio-1I to ensure that no indirect impacts occur to nesting birds and tree-nesting raptors during project construction. Belding’s orange-throated whiptail is a State Species of Special Concern and is covered under the City’s HMP. Although not observed on-site during the general biological survey, this species has a high potential to occur within the proposed project site due to the presence of suitable coastal sage scrub and disturbed habitats. If avoidance measures are not in place, then project construction could result in potential significant direct impacts to this species. The project incorporates PEIR mitigation measure Bio- 2A to ensure that habitat-based mitigation mitigates for impacts to habitat supporting Belding’s orange- throated whiptail. Mitigation Measures Implementation of the following mitigation measures would ensure project consistency with the protection of any species identified as a candidate, sensitive, or special-status species. Bio-1D Avoidance of Nesting Birds and Raptors. To prevent direct impacts to nesting birds, including raptors, protected under the federal MBTA and CDFG Code, the City and CMWD shall enforce the following: Prior to removal or damage of any active nests or any tree pruning or removal operations during the prime nesting seasons, that being from March 15 to May 30, a certified biologist shall survey the trees to determine if there are any active nests within 500 feet of the area of tree removal or pruning. If any active nests are located within 500 feet, no tree pruning or removal operations can occur until the nests are vacated or until the end of the prime breeding season, whichever occurs later. In addition, prior to any tree removal or pruning operations proposed outside of the prime nesting season but within the period of January 15 to September 15, a confirmation is required from a certified biologist that no disturbance to active Sept 20, 2023 Item #2 Page 190 of 256 nests or nesting activities would occur. Documentation from a certified biologist consistent with these requirements shall be submitted to the City Planner for review and approval. A note to this effect shall be placed on the construction plans. Bio-1E Pre-Construction Biological Resource Surveys. Prior to the construction of CIP projects or portions of projects that will occur within disturbed or developed land, but will be sited immediately adjacent to an undeveloped open space area (i.e., an area supporting naturalized habitat, sensitive habitat, and/or habitat potentially suitable for special status species), the City and CMWD shall retain a qualified biologist to perform a pre-construction survey to verify existing biological resources adjacent to the project construction areas. The City and CMWD shall provide the biologist with a copy of the CIP project plans that clearly depict the construction work limits, including construction staging and storage areas, in order to determine which specific portion(s) of the project will require inspection of adjacent open space areas during the pre-construction survey. At a minimum, the biologist shall perform a visual inspection of the adjacent open space area in order to characterize the existing habitat types and determine the likelihood for special status species to occur, including the coastal California gnatcatcher, migratory songbirds, and other bird species with the potential to breed in the area. The pre-construction survey results shall be submitted to the City and CMWD prior to construction in order to verify the need for the additional construction measures proposed within Bio-1F through Bio-1I below. Bio-1F Orange Construction Fencing. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the City and CMWD shall retain a qualified biologist to supervise the installation of temporary orange construction fencing, which clearly delineates the edge of the approved limits of grading and clearing, and the edges of environmentally sensitive areas that occur beyond the approved limits. This fencing shall be installed prior to construction and maintained for the duration of construction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified. Temporary orange fencing shall be removed upon completion of construction of the project. The City shall verify the implementation of this measure prior to and concurrent with construction. Bio-1G Construction-Related Noise. Construction noise created during the general breeding season (January 15 to September 15) that could affect the breeding of the coastal California gnatcatcher, migratory songbirds, and other bird species associated with adjacent undeveloped areas shall be avoided. No loud construction noise (exceeding 60 dBA hourly average, adjusted for ambient noise levels, at the nesting site) may take place within 500 feet of active nesting sites during the general breeding season (January 15 through September 15). If it is confirmed through the implementation of mitigation measure Bio- 1E that the CIP project could result in construction-related noise impacts to breeding birds during the general breeding season, the City and CMWD shall retain a qualified biologist to monitor the construction Sept 20, 2023 Item #2 Page 191 of 256 operations. The biological monitor shall be present to monitor construction activities that occur adjacent to the undeveloped open space area that potentially supports breeding birds. The monitor shall verify that construction noise levels do not exceed 60 dBA hourly average and shall have the ability to halt construction work, if necessary, and confer with the City, USFWS, and CDFG to ensure the proper implementation of additional protection measures during construction. The biologist shall report any violation to the USFWS and/or CDFG within 24 hours of its occurrence. Bio-1H Construction Staging Areas. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the City and CMWD shall design final CIP project construction staging areas such that no staging areas shall be located within sensitive habitat areas. The construction contractor shall receive approval from the City Planning & Engineering Divisions prior to mobilization and staging of equipment outside of the project boundaries. Bio-1I Contractor Training. If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas and/or habitat potentially suitable for special status species, the City and CMWD shall retain a qualified biologist to attend pre-construction meetings to inform construction crews of the sensitive resources and associated avoidance and/or minimization requirements. Conclusions Project implementation could result in significant impacts to nesting birds and raptors, including special- status avian species (i.e., coastal California gnatcatcher, California horned lark), with the potential to nest within or adjacent to the project site. Implementation of the mitigation measures detailed above would ensure that potential impacts are reduced to less than significant. Project implementation could also result in significant impacts to Belding’s orange-throated whiptail. Implementation of habitat-based mitigation discussed below would ensure that potential impacts are reduced to less than significant. Issue 2: Sensitive Natural Communities Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the CDFW or USFWS? Impact Analysis The proposed project would result in impacts to Diegan coastal sage scrub that was previously restored. Unoccupied Diegan coastal sage scrub is considered a sensitive natural community under the Carlsbad HMP, falling into Habitat Group D. Disturbed Habitat is Habitat Group F. Impacts to these habitats require mitigation per PEIR mitigation measure Bio-2A. Habitat impacts for the project are depicted on Figure 7, Vegetation and Sensitive Resources Impacts and summarized below within Table 2, Vegetation Community/Land Use Impacts. Sept 20, 2023 Item #2 Page 192 of 256 Table 2 VEGETATION COMMUNITY/LAND USE IMPACTS Vegetation Community Habitat Group Impacts (acres) Diegan Coastal Sage Scrub (unoccupied, including disturbed and restored) D 0.04 Disturbed Habitat F 0.04 TOTAL 0.08 Mitigation Measures Bio-2A Habitat Compensation for Projects within the City of Carlsbad. If it is demonstrated through the implementation of mitigation measure Bio-1A that applicable CIP projects could directly impact sensitive natural communities, including Habitat Groups A, B, C, D, E, and F specified in Table 11 and Section D.6 of the City of Carlsbad HMP, the City and CMWD shall implement the following: 1. Mitigation for unavoidable impacts to Habitat Groups A, B, C, D, E, and F shall be provided according to the ratios specified below and consistent with Table 11 and Section D.6 of the City of Carlsbad HMP: 2. Impacts to Habitat Groups D, E, and F shall be mitigated at the Lake Calavera Mitigation Bank in accordance with Appendix B of the City of Carlsbad HMP for covered city projects that are eligible to mitigate impacts at the Lake Calavera Mitigation Bank. The project will mitigate for impacts to 0.04 acre of coastal sage scrub and 0.04 acre of disturbed habitat with 0.04 acre (mitigation rounded to the nearest 0.01 acre) at the Lake Calavera Mitigation Bank. Sept 20, 2023 Item #2 Page 193 of 256 Conclusion Project implementation could result in significant impacts to coastal sage scrub and disturbed habitat, both of which are considered sensitive by the Carlsbad HMP. Implementation of the mitigation measure Bio-2A detailed above would ensure that potential impacts are reduced to less than significant. Issue 3: Jurisdictional Wetlands and Waterways Would the project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the federal CWA (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Impact Analysis No jurisdictional wetlands or waterways occur within the project site or immediate surrounding area. Mitigation Measures No mitigation is required. Conclusion The project would not result in impacts to wetlands or waterways. Issue 4: Wildlife Movement and Nursery Sites Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory corridors, or impede the use of native wildlife nursery sites? Impact Analysis The project site is located within Core 5 of the Carlsbad HMP; however, the project is sited within existing disturbed and developed land that is subject to regular maintenance. As the project development has been sited within existing disturbed and developed areas and a very small (less than 0.1-acre) area of previously restored Diegan coastal sage scrub, the potential impact on wildlife movement and nursery sites would be less than significant, and no additional mitigation is required. Mitigation Measures No mitigation is required. Conclusion Project implementation would not result in significant impacts on wildlife movement and nursery sites. Less than significant impacts would occur, and mitigation is not required. Sept 20, 2023 Item #2 Page 194 of 256 Issue 5: Local Policies and Ordinances Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Impact Analysis No local policies or ordinances pertaining to biological resources are applicable to the project except for the Carlsbad HMP, which is discussed below. The project would primarily occur within the existing disturbed areas and public road ROW. No impact or conflict would occur. Mitigation Measures No mitigation is required. Conclusion The project would not conflict with local policies or ordinances protecting biological resources, and mitigation is not required. Issue 6: Adopted Conservation Plans Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Issue 6 Impact Analysis The project is located within the Carlsbad HMP, and an HMP Permit from the City will be required. The project is consistent with the Carlsbad HMP because it has been sited within existing disturbed and developed land subject to regular maintenance and would only impact a very small (less than 0.1-acre) area of previously restored Diegan coastal sage scrub. Mitigation is provided for direct and indirect impacts consistent with the Carlsbad HMP, as discussed above. The mitigation included here is consistent with the PEIR for the 2012 CMWD Water Master Plans Update, which was found to be consistent with the Carlsbad HMP. No conflict with an adopted plan would occur. Mitigation Measures No mitigation is required. Conclusion The project would not conflict with any adopted plan, and mitigation is not required. Sept 20, 2023 Item #2 Page 195 of 256 FEDERAL CONFORMANCE ANALYSIS FOR BIOLOGICAL RESOURCES ISSUES Issue 1: Federal Endangered Species Act, Section 10 Does the project involve any direct effects from construction activities, or indirect effects such as growth inducement that may affect federally listed threatened or endangered species or their critical habitat that are known, or have a potential, to occur on site, in the surrounding area, or in the service area? The project site is situated mainly on developed land and does not overlap with any critical habitats. Therefore, the proposed action would not affect Critical Habitat. The project as proposed occurs approximately 140 feet from the occupied habitat for the federally-listed coastal California gnatcatcher. With the implementation of mitigation measures Bio-1D through Bio-1I, no impacts to breeding coastal California gnatcatcher would occur. Implementation of mitigation measure Bio-2A would mitigate for impacts to potential gnatcatcher habitat. With these mitigation measures, the project is consistent with the Carlsbad HMP and has incidental take coverage under the Carlsbad HMP. Further discussion is provided below regarding the potential effects of the proposed action on federally- listed species. Federally-Listed Plant Species. No federally-listed endangered (FE), threatened (FT), or candidate (FC) plant species are known or have the potential to occur in the vicinity of the project site; therefore, the project would not affect any federally-listed plant species. Federally-Listed Animal Species. In total, one FT animal species is known to occur in the vicinity of the project site (Appendix D): • Coastal California gnatcatcher; FT The project site supports marginal habitat for coastal California gnatcatcher, and a pair was observed within 500 feet of the project site. The project was carefully designed to avoid and minimize impacts on this species by developing the most disturbed area of the site, which is located across the street and approximately 140 feet away from the edge of the occupied habitat. The project may affect the coastal California gnatcatcher or suitable habitat for this species. Mitigation Measures The implementation of mitigation measures Bio-1D through Bio-1I and Bio-2A described above would ensure project consistency with the Carlsbad HMP. Coastal California gnatcatcher is a covered species under the Carlsbad HMP; therefore, the project would be in conformance with the ESA. Conclusion If unmitigated, project implementation may affect federally listed species; however, because the project was found to conform with the Carlsbad HMP, the project applicant has take authorization for incidental take of listed species as a third party beneficiary under the Endangered Species Act (ESA) Section 10 Permit issued to the City by the USFWS. Sept 20, 2023 Item #2 Page 196 of 256 Issue 2: Magnuson-Stevens Fishery Conservation and Management Act, Essential Fish Habitat Does the project involve any direct effects from construction activities, or indirect effects such as growth inducement that may adversely affect essential fish habitat? The project lacks marine resources and Essential Fish Habitat regulated under the Magnuson-Stevens Fishery Conservation and Management Act. No Essential Fish Habitat occurs in the immediate vicinity of the project site. Therefore, the project would not affect Essential Fish Habitat and would be in conformance with the Magnuson-Stevens Fishery Conservation and Management Act. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on essential fish habitat, and no mitigation is required. Issue 3: Coastal Zone Management Act Is any portion of the project site located within the coastal zone? The project site is not located within the Coastal Zone. No coastal habitat occurs in the immediate vicinity of the project site. Therefore, the project would not affect any areas designated as Coastal Zone and would be in conformance with the Coastal Zone Management Act. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on areas designated as Coastal Zone, and no mitigation is required. Issue 4: Migratory Bird Treaty Act Will the project affect protected migratory birds that are known, or have a potential, to occur on site, in the surrounding area, or in the service area? Project construction may result in the removal or trimming of vegetation during the general bird nesting season (January 15 through September 15), and, therefore, would have the potential to adversely affect nesting birds protected under the MBTA. Implementation of mitigation measures described above would ensure the appropriate pre-maintenance surveys and avoidance measures are completed to prevent adverse effects on nesting birds. Sept 20, 2023 Item #2 Page 197 of 256 Mitigation Measures The implementation of mitigation measures Bio-1D through Bio-1I described above would ensure project consistency with the protection of migratory birds; therefore, the project would be in conformance with the MBTA. Conclusion With the implementation of mitigation measures Bio-1D through Bio-1I described above, the project would result in no effect on migratory birds and would be in conformance with the MBTA. Issue 5: Protection of Wetlands Does any portion of the project boundaries contain areas that should be evaluated for wetland delineation or require a permit from the United States Army Corps of Engineers? No jurisdictional wetlands occur within the project vicinity. Therefore, the project would not affect wetlands and would not require a permit from the USACE. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on areas subject to a permit from the USACE, and no mitigation is required. Issue 6: Wild and Scenic River Act Is any portion of the project located within a wild and scenic river? The proposed project is not planned on or in the immediate vicinity of areas designated as Wild and Scenic River. Therefore, the proposed project would not affect any areas designated as Wild and Scenic River and would be in conformance with the Wild and Scenic Rivers Act. Mitigation Measures No mitigation is required. Conclusion The project would have no direct or indirect effect on areas subject to the Wild and Scenic River Act, and no mitigation is required. CONCLUSION In conclusion, with the proposed mitigation the District’s planned maintenance activities would result in no impacts or less than significant impacts on special status plant species, sensitive natural Sept 20, 2023 Item #2 Page 198 of 256 communities/sensitive habitat types, federally protected wetlands and other waters, wildlife corridors and nursery sites, local policies and ordinances, and regional conservation plans. The project would be consistent with the Carlsbad HMP, which provides coverage for the coastal California gnatcatcher. The construction activities would further have no effect on federally listed plants, federally designated critical habitat, essential fish habitat, coastal resources, federally protected wetlands, and wild and scenic areas. The PEIR and Addendum did not list the Maerkle project as requiring biological mitigation; however, the incorporation of ground disturbance in the project makes some of the biological mitigation measures applicable to the project, as summarized here. This report satisfies PEIR mitigation measure Bio-1A, which requires project-level biological surveys for applicable CIP projects. Mitigation measure Bio-1B, which requires protocol-level surveys for special-status wildlife species, is not applicable to the project because the habitat to be impacted by the project consists of disturbed habitat and restored coastal sage scrub that is located in a thin strip between a paved road and a water tank. The restored coastal sage scrub is dominated by San Diego sunflower, making it a less preferred habitat for the coastal California gnatcatcher than the undisturbed coastal sagebrush-dominated coastal sage scrub located on hardline preserve lands to the south of the project site, which was found to be occupied. Mitigation measures Bio-1C and Bio-2B are not applicable to this project because this project is located within the Carlsbad HMP. Mitigation measures Bio-1D through Bio-1I and Bio-2A are applicable to the current project description and will be applied to this project. With the incorporation of mitigation measures Bio-1D through Bio-1I and Bio-2A, project impacts are mitigated to less than significant consistent with the PEIR, and no additional impacts or mitigation not discussed in the PEIR have been identified for the project.

(HELIX) was contracted to conduct a project site-specific review for the Carlsbad Municipal Water District (CMWD) Maerkle Motorized Valves Project (project), located in the City of Carlsbad (City), San Diego County, California. HELIX conducted a records search update at the South Coastal Information Center (SCIC), requested a Sacred Lands File search from the Native American Heritage Commission (NAHC), and conducted a review of historic topographic maps and aerial imagery. In summary, the project area is within a previously disturbed area and is not near a known cultural resource and no further cultural resources work is recommended. PROJECT LOCATION AND DESCRIPTION The project site is located south of State Route 78 and north of Agua Hedionda Creek, within an unsectioned portion of the Agua Hedionda land grant, in Township 12 South, Range 4 West on the San Luis Rey U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle (Figures 1 and 2, Regional Location and USGS Topography, respectively). The project site is located north of Lost Monos Canyon, adjacent to the Maerkle Reservoir (Figure 3, Aerial Photograph). The project involves the replacement of two existing isolation valves and piping with new motorized valves and piping, which would automate water system operations at this location. The existing 24-inch and 42-inch valves divert water into the 10-million-gallon tank and the 200-million-gallon reservoir. The new valves are to be installed in a new underground vault at the base of the slope to make it easier to access the valves and to improve worker safety. Facility improvements at the Maerkle Reservoir are included as Capital Improvement Program (CIP) project W-9 in the August 2019 Addendum to the City of Carlsbad Sewer Master Plan and Carlsbad Municipal Water District Water and Recycled Water Master Plans Update Program Environmental Sept 20, 2023 Item #2 Page 214 of 256 Impact Report (PEIR) (EIR 12-01; SCH No. 2012021006), as well as in the PEIR itself as Project R7. Per the PEIR’s Mitigation Monitoring and Reporting Program (MMRP), CIP projects proposed near a known cultural resource or projects that would result in ground-disturbing activities in a previously undisturbed area require a project-level cultural resources investigation. As outlined in Cul-1 in the MMRP, the cultural resources investigation includes this initial step: 1. A CIP project site-specific review of the records search data at the South Coastal Information Center shall be conducted to determine if the CIP project site has been subjected to a professional survey. a. If a current cultural resources report addressing potential impacts on cultural resources is available, the city or CMWD shall implement the mitigation measures provided within the report. In the event that a current and valid report is not available, or if the entirety of the CIP project site has not been professionally surveyed, then an updated records search shall be performed. b. In accordance with the 2017 Tribal, Cultural and Paleontological Guidelines, the City or CMWD shall contact the NAHC and local tribal governments for input on the project in order to identify any additional Native American resources that may not be included in the records search. REGULATORY FRAMEWORK Cultural resources are defined as buildings, sites, structures, or objects, each of which may have historical, architectural, archaeological, cultural, and/or scientific importance. The California Environmental Quality Act (CEQA), Public Resources Code (PRC) 21084.1, and California Code of Regulations (CCR) Title 14 Section 15064.5, address determining the significance of impacts to archaeological and historic resources and discuss significant cultural resources as “historical resources,” which are defined as: • resource(s) listed or determined eligible by the State Historical Resources Commission for listing in the California Register of Historical Resources (CRHR; 14 CCR Section 15064.5[a][1]) • resource(s) either listed in the National Register of Historic Places (NRHP) or in a “local register of historical resources” or identified as significant in a historical resource survey meeting the requirements of Section 5024.1(g) of the PRC, unless “the preponderance of evidence demonstrates that it is not historically or culturally significant” (14 CCR Section 15064.5[a][2]) • resources determined by the Lead Agency to meet the criteria for listing on the CRHR (14 CCR Section 15064.5[a][3]) For listing in the CRHR, a historical resource must be significant at the local, state, or national level under one or more of the following four criteria: 1. It is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States; Sept 20, 2023 Item #2 Page 215 of 256 2. It is associated with the lives of persons important to local, California, or national history; 3. It embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master or possesses high artistic values; and/or 4. It has yielded or has the potential to yield information important to the prehistory or history of the local area, California, or the nation. Under 14 CCR Section 15064.5(a)(4), a resource may also be considered a “historical resource” for the purposes of CEQA at the discretion of the lead agency. Significant resources must retain enough of their historic character or appearance to be recognizable as historical resources and to convey the reasons for their significance. Resource integrity, which is the authenticity of a historical resource’s physical identity evidenced by the survival of characteristics that existed during the resource’s period of significance, is evaluated with regard to the retention of location, design, setting, materials, workmanship, feeling, and association. In an archaeological deposit, integrity is assessed with reference to the preservation of material constituents and their culturally and historically meaningful spatial relationships. A resource must also be judged with reference to the CRHR criteria under which it is proposed for eligibility. City of Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines In 1990, the City developed guidelines for the treatment of cultural resources. The guidelines were consistent with the cultural and historical resource guidelines set forth by the National Historic Preservation Act (NHPA), as amended, and CEQA, established standards of performance for resource investigation, and presented a systematic method of preserving identified resources. Carlsbad City Council Policy No. 83, adopted in 2016, called for the City to: “recognize [the City’s] responsibility to protect with improved certainty the important historical and cultural values of current Tribal Cultural Resources within the City limits and to establish an improved framework for the City's consultations with Native American Tribes that are traditionally and culturally affiliated with the City of Carlsbad, including the San Luis Rey Band of Mission Indians.” In 2017, updated Tribal, Cultural and Paleontological Guidelines were released to address the regulatory changes and the addition of new procedures to address additional requirements that had emerged since 1990 (ECORP 2017). The guidelines provide a framework for the roles and responsibilities of those responsible for compliance with the Guidelines and provide the processes by which cultural resources are assessed under the Guidelines. PROJECT SITE-SPECIFIC REVIEW METHODS HELIX conducted a record search of the project area and a half-mile radius at the SCIC on March 7, 2022. Reports of previous cultural resources studies and site forms for cultural resources were reviewed to determine previous survey coverage and to assess the existence of, or potential for, cultural resources to be present within the project area. Historic topographic maps and aerial imagery (NETR Online 2022) were reviewed to identify historic structures and land use in the area. In addition, modern aerial imagery was reviewed to assess the level disturbed within the project area. A pedestrian field survey was not conducted as part of this review. Sept 20, 2023 Item #2 Page 216 of 256 The NAHC was contacted for a Sacred Lands File search on March 10, 2022, to which the NAHC responded in a letter dated April 26, 2022. CMWD is currently conducting outreach to the Native American contacts identified by the NAHC. PROJECT SITE-SPECIFIC REVIEW RESULTS Records Search The records search indicated that 16 cultural resources studies have been conducted within the records search limits; of these, two overlap with the project area (Table 1, Previous Studies Within One-Half Mile of the Project Area). In general, the studies within half a mile of the project area include five cultural resource survey reports, three cultural resource studies, two testing reports, two cultural resource evaluations, two environmental documents, a cultural resource inventory, and a cultural resource investigation.

The cultural resource survey for the upgrade and expansion of the Squires Reservoir was conducted in 1988 by WESTEC Services, Inc. and included a records search and intensive cultural survey of a 3,000 linear foot pipeline, pump station, and buried tank near Squires Reservoir (Kyle and Gallegos 1988). The 1988 survey area encompassed the entirety of the current project area. A single isolated mano fragment was observed during the 1988 survey, though no site record appears to have been produce (Kyle and Gallegos 1988). As such, it is unknown if the isolate was located within the current project area; however, it was noted to have been observed in area containing plowed fields, which according to a review of aerial imagery from 1988 indicates the isolate was identified to the north of the project area. The records search resulted in the identification of ten cultural resources within the records search limits, all of which are located a quarter-mile or more from the project area (Table 2, Cultural Resources Recorded within One Half-Mile of the Project Area). In general, the resources include shell scatters, artifact scatters, milling areas, and the historic Rancho de los Quiotes to Mission San Luis Rey trail.

The NAHC further noted to contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians for additional information regarding the positive results. CMWD is currently conducting outreach to these two tribes identified by the NAHC. Historic Topographic Maps and Aerial Imagery No structures are visible within the project area on the 1893 and 1901 Oceanside (1:62,500), or 1901 San Luis Rey (1:125,000) topographic maps, though a trail is recorded north of the project area. This trail is not present on the 1948 San Luis Rey (1:62,500) map, though one is present to the west. Records indicate that the City started construction on the nearby Squires Dam in the early 1950s; by the time the 1968 topographic map was made, the Squires Dam had been finished and the adjacent Squires Reservoir—today called the Maerkle Reservoir—is shown on the map adjacent to Mount Hinton (O’Kelly, n.d.). Aerial photographs show the finished and filled reservoir; the 1964 aerial photograph shows the area graded, likely due to the construction of the reservoir and related infrastructure (NETR Online 2022). The area surrounding the Maerkle site was mass-graded prior to the 1990 aerial photograph in preparation for the expansion of the facility, which consisted of the construction of the buried tank, pumpstation, and additional pipelines; this photograph shows the completion of the tank just to the west of the reservoir (Figure 4, 1990 Aerial Photograph). Subsequent aerial photographs show the tank buried and covered in new vegetation (NETR Online 2022). Environmental Conditions Geologically, the project alignments are underlain by old tonalite dating to the middle Cretaceous (Kennedy and Tan 2007). The soil present within the project site consists entirely of Cieneba coarse sandy loam (5 to 15 percent slopes, eroded; Natural Resources Conservation Service 2017). This series consists of excessively drained, very shallow to shallow coarse sandy loams formed in material weathered from granitic rock (Bowman 1973). Sept 20, 2023 Item #2 Page 219 of 256 CONCLUSIONS AND RECOMMENDATIONS HELIX conducted a records search for the project area and a half-mile search radius, contacted the NAHC for a Sacred Lands File search, and conducted a review of historic topographic maps and aerial imagery. The record search indicated that a total of 16 studies had been conducted, and ten cultural resources had been recorded, within the half-mile search radius. One survey conducted in 1988 encompassed the project area and resulted in the identification of isolated mano fragment, likely to the north of the project area (Kyle and Gallegos 1988). No other cultural resources have recorded within or near the project area. The Sacred Lands File search were positive for the project vicinity; CMWD is currently conducting additional outreach related to the positive result. Per Cul-1 (2) in the PEIR MMRP, for those CIP project site(s) not addressed by a current cultural resources report (produced within five years of project proposal), a project-level Phase I Cultural Resources Survey shall be prepared in accordance with the 2017 Guidelines. While the cultural resources survey that encompassed the project area was conducted over 30 years ago, the review of aerial imagery undertaken as part of this review indicates that the entirety of the project area, as well as the area surrounding it, was rough graded in 1990 for the upgrade and expansion of the Maerkle Reservoir, which included an installation of a buried tank that is situated directly north of the project area (Figure 4). Additionally, the review of geologic and soil conditions for the project area do not indicate the presence of young alluvium soils within the project area, which typically contain a higher potential for buried cultural resources to be present. As such, it is likely the case that the grading that occurred in 1990 removed any potential for cultural resources to still be present within the project area. As the project area is within a previously disturbed area and is not near a known cultural resource, no further cultural resources work is recommended, including a project-level Phase I cultural resources survey or archaeological construction monitoring.

The results were positive. Please contact the La Jolla Band of Luiseno Indians and the San Luis Rey Band of Mission Indians on the attached list for information. Please note that tribes do not always record their sacred sites in the SLF, nor are they required to do so. A SLF search is not a substitute for consultation with tribes that are traditionally and culturally affiliated with a project’s geographic area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites, such as the appropriate regional California Historical Research Information System (CHRIS) archaeological Information Center for the presence of recorded archaeological sites. Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. Please contact all of those listed; if they cannot supply information, they may recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received. If you receive notification of change of addresses and phone numbers from tribes, please notify the NAHC. With your assistance, we can assure that our lists contain current information. If you have any questions or need additional information, please contact me at my email address: Andrew.Green@nahc.ca.gov.
