The site is located on the south side of La Costa Avenue, between El Camino Real and Castilla Way and currently consists of a vacant lot totaling 8.18 acres. The site is surrounded by an existing multi-family residential project to the west, a vacant lot to the east, duplexes to the south and single-family residences to the north. Three tiers of buildings are proposed with six, six-plex buildings, two three-plex buildings and four, four-plex buildings. Access to the site is fiom La Costa Avenue and the project's internal private driveways will provide access to individual units. The buildings will not exceed 35' in height and will comply with all standards of the RD-M Zone and Planned Development Ordinance. The units will range in size from 1,340 to 2,016 square feet. A 14,330 square foot recreation area will be located in the northeastern comer of the subject site. The northern property boundary, adjacent to La Costa Avenue, is a moderately steep slope. The middle section of the site is relatively flat with very steep slopes located on the southwestern, southem, and southeastern portions of the property. DETERMINATION: The City of Carlsbad has conducted an environmental review of the above-described project pursuant to the Guidelines for Implementation of the California Environmental Quality Act and the Environmental Protection Ordinance of the City of Carlsbad. As a result of said review, the initial study (EIA Part 2) identified potentially significant effects on the environment, and the City of Carlsbad finds as follows: Although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. The proposed project MAY have "potentially significant impact(s)" on the environment, but at least one potentially significant impact 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. (Mitigated Negative Declaration applies only to the effects that remained to be addressed). 0 Although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, nothing further is required. A copy of the initial study (EIA Part 2) documenting reasons to support the Negative Declaration is on file in the Planning Department, 1635 Faraday Avenue, Carlsbad, California 92008.

The middle section of the site is relatively flat with very steep slopes located on the southwestern, southern, and southeastern portions of the property. PROPOSED DETERMINATION: The City of Carlsbad has conducted an environmental review of the above described project pursuant to the Guidelines for Implementation of the California Environmental Quality Act and the Environmental Protection Ordinance of the City of Carlsbad. As a result of said review, the initial study (EL4 Part 2) identified potentially significant effects on the environment, but (1) revisions in the project plans or proposals made by, or agreed to by, the applicant before the proposed negative declaration and initial study are released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effect on the environment would occur, and (2) there is no substantial evidence in light of the whole record before the City that the project “as revised” may have a significant effect on the environment. Therefore, a Mitigated Negative Declaration will be recommended for adoption by the City of Carlsbad City Council. A copy of the initial study (EIA Part 2) documenting reasons to support the proposed Mitigated Negative Declaration are on file in the Planning Department, 1635 Faraday Avenue, Carlsbad, California 92008. Comments from the public are invited. Please submit comments in writing to the Planning Department within 30 days of the date of this notice. The proposed project and Mitigated Negative Declaration are subject to review and approval/adoption by the City of Carlsbad Planning Commission and City Council. Additional public notices will be issued when those public hearings are scheduled. If you have any questions, please call Saima Qureshy in the Planning Department at (760) 602-4619.

(To be completed by the Lead Agency) 0 IXI 0 0 0 I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have “potentially significant impact(s)” on the environment, but at least one potentially significant impact 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. A Negative Declaration is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, nothing further is required. \2-/ \6 /03 Planner Signature Date Planner Signature \2-/ \6 /03 Date 3 Rev. 07/03/02 ENVIRONMENTAL IMPACTS STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City conduct an Environmental Impact Assessment to determine if a project may have a significant effect on the environment. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological and human factors that might be impacted by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report (Em), Negative Declaration, or to rely on a previously approved EIR or Negative Declaration. A brief explanation is required for all answers except “No Impact” answers that are adequately supported by an information source cited in the parentheses following each question. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved. A “No Impact” answer should be explained when there is no source document to refer to, or it is based on project-specific factors as well as general standards. “Less Than Significant Impact” applies where there is supporting evidence that the potential impact is not significantly adverse, and the impact does not exceed adopted general standards and policies. “Potentially Significant Unless Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less Than Significant Impact.” The developer must agree to the mitigation, and the City must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect is significantly adverse. Based on an “EIA-Part 11”, if a proposed project could have a potentially significant adverse effect on the environment, but potentially significant adverse effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, and none of the circumstances requiring a supplement to or supplemental EIR are present and all the mitigation measures required by the prior environmental document have been incorporated into this project, then no additional environmental document is required. When “Potentially Significant Impact” is checked the project is not necessarily required to prepare an EIR if the significant adverse effect has been analyzed adequately in an earlier EIR pursuant to applicable standards and the effect will be mitigated, or a “Statement of Overriding Considerations” has been made pursuant to that earlier EIR. A Negative Declaration may be prepared if the City perceives no substantial evidence that the project or any of its aspects may cause a significant adverse effect on the environment. If there are one or more potentially significant adverse effects, the City may avoid preparing an EIR if there are mitigation measures to clearly reduce adverse impacts to less than significant, and those mitigation measures are agreed to by the developer prior to public review. In this case, the appropriate “Potentially Significant Impact Unless Mitigation Incorporated” may be checked and a Mitigated Negative Declaration may be prepared. 4 Rev. 07/03/02 0 An EIR the following circumstances: (1) the potentially significant adverse effect has not been discussed or mitigated in an earlier EIR pursuant to applicable standards, and the developer does not agree to mitigation measures that reduce the adverse impact to less than significant; (2) a “Statement of Overriding Considerations” for the significant adverse impact has not been made pursuant to an earlier EIR (3) proposed mitigation measures do not reduce the adverse impact to less than significant; or (4) through the EM-Part I1 analysis it is not possible to determine the level of significance for a potentially adverse effect, or determine the effectiveness of a mitigation measure in reducing a potentially significant effect to below a level of significance. be prepared if “Potentially Significant Impact” is checked, and including but not limited to A discussion of potential impacts and the proposed mitigation measures appears at the end of the form under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attention should be given to discussing mitigation for impacts, which would otherwise be determined significant. 5 Rev. 07/03/02 Potentially Significant Unless Mitigation Incorporated Issues (and Supporting Information Sources).

EARLIER ANALYSES Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case a discussion should identify the following on attached sheets: a) Earlier analyses used. Identify earlier analyses and state where they are available for review. b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation measures. For effects that are “Less Than Significant with Mitigation Incorporated,” describe the mitigation measures, which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 14 Rev. 07/03/02 DISCUSSION OF ENVIRONMENTAL EVALUATION PROJECT DESCRIPTION The proposed project is for a Tentative Tract Map, Site Development Plan, Condominium Permit and Hillside Development Permit to allow for the development of 58 condominium units on an 8.18 acre site. The project site is located on the south side of La Costa Avenue adjacent to and east of the Marbella Condominiums. Three tiers of buildings are proposed. The two northernmost tiers (closest to La Costa Avenue) will have access from Driveway “B”. The southernmost tier (with the highest elevation) will have access from Driveway “A”. The Driveway “B” buildings include 2, tri-plexes and 6, six-plexes (one tri-plex and three six-plexes on each side of Driveway “B”). The Driveway “A” buildings will consist of 4, four-plexes. The buildings will not exceed 35’ in height and will comply with all standards of the RD-M Zone and Planned Development Ordinance. The units will range in size from 1,340 to 2,016 square feet. A 14,330 square foot recreation area will be located in the northeastern corner of the project site. The amenities in the recreation area include: swimming pool, spa, barbeque area, bathroodchanging room, play equipment, and turf play area. AESTHETICS No Impact. The project will not have a substantial adverse effect on a scenic vista since the site is located in an urbanized area and will be constructed in compliance with the maximum 35’ height limitation allowed in the RD-M zone and the archtectural guidelines contained in the Planned Development Ordinance. Development of the site with a multi-family condominium project would be consistent with the surrounding development pattern. AGRICULTURAL RESOURCES No Impact. There will be no impact on agricultural resources due to the proposed project as the site is not designated as or used as farmland. The subject site is zoned for multi-family residential development (RD-M) and is not subject to a Williamson Act Contract. The project would not result in other changes to the environment that would result in the conversion of farmland to non-agricultural uses. The project would be characterized as infill development and has been surrounded by residential development for many years. AIR QUALITY-Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. The project site is located in the San Diego Air Basin which is a federal and state non-attainment area for ozone (03), and a state non-attainment area for particulate matter less than or equal to 10 microns in diameter (PM,o). The periodic violations of national Ambient Air Quality Standards (AAQS) in the San Diego Air Basin (SDAB), particularly for ozone in inland foothill areas, requires that a plan be developed outlining the pollution controls that will be undertaken to improve air quality. In San Diego County, this attainment planning process is embodied in the Regional Air Quality Strategies (RAQS) developed jointly by the Air Pollution Control District (APCD) and the San Diego Association of Governments (SANDAG). A plan to meet the federal standard for ozone was developed in 1994 during the process of updating the 1991 state- mandated plan. This local plan was combined with plans from all other California non-attainment areas having serious ozone problems and used to create the California State Implementation Plan (SIP). The SIP was adopted by the Air Resources Board (ARB) after public hearings on November 9th through 10th in 1994, and was forwarded to the Environmental Protection Agency (EPA) for approval. After considerable analysis and debate, particularly regarding airsheds with the worst smog problems, EPA approved the SIP in mid-1996. The proposed project relates to the SIP andlor RAQS through the land use and growth assumptions that are incorporated into the air quality planning document. These growth assumptions are based on each city’s and the County’s general plan. If a proposed project is consistent with its applicable General Plan, then the project presumably has been anticipated with the regional air quality planning process. Such consistency would ensure that the project would not have an adverse regional air quality impact. Section 15125(B) of the State of California Environment Quality Act (CEQA) Guidelines contains specific reference to the need to evaluate any inconsistencies between the proposed project and the applicable air quality management plan. Transportation Control Measures (TCMs) are part of the RAQS. The RAQS and TCM plan set forth the steps needed to accomplish attainment of state and federal ambient air quality standards. The California 15 Rev. 07/03/02 Air Resources Board provides criteria for determining whether a project conforms with the RAQS which include the following: 0 Is a regional air quality plan being implemented in the project area? Is the project consistent with the growth assumptions in the regional air quality plan? The project area is located in the San Diego Air Basin, and as such, is located in an area where a RAQS is being implemented. The project is consistent with the growth assumptions of the City’s General Plan and the RAQS. Therefore, the project is consistent with the regional air quality plan and will in no way conflict or obstruct implementation of the regional plan. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less Than Significant Impact. The closest air quality monitoring station to the project site is in the City of Oceanside. Data available for this monitoring site through April, 2002 indicate that the most recent air quality violations recorded were for the state one hour standard for ozone (one day in both 2000 and 2001) and one day in 2001 for the federal 8-hour average for ozone and one day for the 24-hour state standard for suspended particulates in 1996. No violations of any other air quality standards have been recorded recently. The project would involve minimal short-term emissions associated with grading and construction. Such emissions would be minimized through standard construction measures such as the use of properly tuned equipment and watering the site for dust control. Long-term emissions associated with travel to and from the project will be minimal. Although air pollutant emissions would be associated with the project, they would neither result in the violation of any air quality standard (comprising only an incremental contribution to overall air basin quality readings), nor contribute substantially to an existing or projected air quality violation. Any impact is assessed as less than significant. c) 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? Less Than Significant Impact. The Air Basin is currently in a non-attainment zone for ozone and suspended fine particulates. The proposed project would represent a contribution to a cumulatively considerable potential net increase in emissions throughout the air basin. As described above, however, emissions associated with the proposed project would be minimal. Given the limited emissions potentially associated with the proposed project, air quality would be essentially the same whether or not the proposed project is implemented. According to the CEQA Guidelines Section 15130 (a) (4), the proposed project’s contribution to the cumulative impact is considered de minimus. Any impact is assessed as less than significant. d) Expose sensitive receptors to substantial pollutant concentrations? No Impact. As noted above, the proposed project would not result in substantial pollutant emissions or concentrations. In addition, there are no sensitive receptors (e.g., schools or hospitals) located in the vicinity of the project. No impact is assessed. e) Create objectionable odors affecting a substantial number of people? No Impact. The construction of the proposed project could generate fumes from the operation of construction equipment, which may be considered objectionable by some people. Such exposure would be short-term or transient. In addition, the number of people exposed to such transient impacts is not considered substantial. IV. BIOLOGICAL RESOURCES A Biological Resources Report and Impact Analysis was prepared for the proposed project by Affinis Environmental Services in August 2002 and was updated in March, 2003. The report and update were based upon surveys of the site conducted in May 2002 (a biological reconnaissance survey) and a literature review. The Biological Resources Report identified four plant communities on the 8-acre project site and project impacts to those communities as follows: 16 Rev. 07/03/02 I PROPOSED HABITAT TYPE/ PLANT COMMUNITY EXISTING IMPACTED ACREAGE ACREAGE Non-Native GrasslandLandscaped Coastal Sage Scrubhlixed Chaparral Landscaped Disturbed Habitat TOTAL NON-IMPACTED 0.6 0.6 1.1 0.3 2.7 0.5 3.6 3.6 8.0 5.0 0 I 0 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 California Department of Fish and Game or U.S. Fish and Wildlife Service? Potentially Significant Unless Mitigation Incorporated. A Biological Resources Report and Impact Analysis was prepared for the proposed project by Affinis Environmental Services in August 2002 and was updated in March, 2003. According to the report, no candidate, sensitive, or special status species have been identified on-site. No California gnatcatchers were observed on or adjacent to the property during the surveys conducted in 2002. The coastal sage scrublmixed chaparral (1.1-ac) found on the site is recognized as a sensitive community by local, state, and federal resource agencies. The proposed project would avoid direct impacts to the coastal sage scrub found on site, with the exception of possible disturbance to 0.3 acres of habitat from brush management and remedial grading. The applicant will acquire 0.3 acres of mitigation credit in a pre-approved mitigation area or mitigation bank to offset this impact. b) Have a substantial adverse effect on any riparian, aquatic or wetland habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by California Department of Fish and Game or U.S. Fish and Wildlife Service? No Impact. No riparian, aquatic, or wetland habitat is present on the site. No habitat under the jurisdiction of the US. Army Corps of Engineers, California Department of Fish and Game, or the Regional Water Quality Control Board would be impacted. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filing, hydrological interruption, or other means? No Impact. See Response (IV b) above. 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? No Impact. According to the Biological Resources Report and Impact Analysis prepared for this project, there are no wildlife corridors or habitat linkages on the project site. Native habitat is very limited on the project site. The coastal sage scrub/chaparral mix is contiguous with habitat to the east, but this off-site area is also relatively small and is surrounded by development on three sides. Overall, the property does not support high-quality biological resources. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? and 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? 17 Rev. 07/03/02 No Impact. The proposed project would not conflict with any HCP, NCCP, or other approved habitat conservation plan, or local policies or ordinances protecting biological resources. It is not within the boundaries of or adjacent to any pre-approved mitigation areas, hardline areas, or standards areas identified in the City’s Draft Habitat Management Plan (HMP). g) Impact tributary areas that are environmentally sensitive? No Impact. See response 1V.b (above). V. CULTURAL RESOURCES No Impact. The subject site is an infill site which is surrounded by residential development and there will be no impacts on cultural resources. There are no known historical, archeological, paleontological, or human remains on the project site. VI. GEOLOGY AND SOILS Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. ii. Strong seismic ground shaking? iii. Seismic-related ground failure, including liquefaction? Less than Significant Impact (a.i. to a.iii.) - There are no Alquist-Priolo Earthquake Fault zones within the City of Carlsbad and there is no other evidence of active or potentially active faults within the City. However, there are several active faults throughout Southern California, and these potential earthquakes could affect Carlsbad. The project site is located in an area of stable soil conditions and the risk of seismic-related ground failure or liquefaction is very minimal (according to City of Carlsbad Geotechnical Hazards Analysis and Mapping Study, November 1992). In addition, a project specific Preliminary Geotechnical Evaluation was prepared by Leighton and Associates dated October 30, 2002. The report states that the potential for Liquefaction, earthquake induced settlement and lateral spread are considered to be low for the site because of the low susceptibility to liquefaction. iv. Landslides? Potentially Significant Unless Mitigation Incorporated. There are known landslide deposits located either inside the limits of the planned grading or directly above and therefore have the potential to affect site development. Due to their potentially compressible nature and the relatively steep basal surface, the landslide deposits within the limits of the planned grading are not considered stable and are generally unsuitable for structural support in their present condition. Corrective measures (i.e. removals to competent material and/or buttressing with compacted fill) will be required to mitigate their potentially compressible nature (Update Preliminary Geotechnical Report, Lot 185, La Costa Avenue South Unit I, Carlsbad, California, prepared by Leighton & Associates, Inc. on October 30, 2002). Geotechnical issues will be reduced to a level considered less than significant through compliance with the mitigation measures recommended in the report. b) Result in substantial soil erosion or the loss of topsoil? Less than Significant Impact. Topsoil encountered during field investigations matches the ungraded portions of the site along the southerly property line. Soils were generally massive, porous, and contained scattered roots and other organics. The potentially compressible topsoil is estimated to be from 1 to 5 feet in thickness; however, localized areas of thicker accumulations of topsoil may be present. Although the soils on the site are relatively prone to erosion, all storm runoff collected onsite will be slowed down to a non-erosive manner prior to discharge off the site by using energy dissipaters. The applicant is required to prepare grading and erosion control plans prior to any construction. In addition, the applicant will be required to re-vegetate the slopes to increase their stability 18 Rev. 07/03/02 (Update Preliminary Geotechnical Report, Lot 185, La Costa Avenue South Unit I, Carlsbad, California, prepared by Leighton & Associates, Inc. on October 30,2002). Geotechnical issues will be reduced to a level considered less than significant through compliance with the mitigation measures recommended in the report. 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? Potentially Significant Unless Mitigation Incorporated. Due to their potential instability and compressible nature, the landslide deposits on the site are considered unstable in their present condition and remedial measures are required (Update Preliminary Geotechnical Report, Lot 185, La Costa Avenue South Unit 1, Carlsbad, California, prepared by Leighton & Associates, Inc. on October 30, 2002). Geotechnical issues will be reduced to a level considered less than significant through compliance with the mitigation measures recommended in the report. d) Be located on expansive soils, as defined in Table 18 - 1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Potentially Significant Unless Mitigation Incorporated. Siltstone and claystone soils of the Santiago Formation are highly expansive and were found on site during field investigations. These expansive soils will be removed where present within 5 feet of finish pad grades and replaced with soils having a lower expansion potential or a special foundation design (i.e. post-tensioned design) will be provided. Incorporation of these mitigation measures into the overall project design will reduce these potential impacts to a level considered less than significant. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available €or the disposal of wastewater? No Impact. Sewers are available to the subject site and the project will be served by a public wastewater system. VII. HAZARDS AND HAZARDOUS MATERIALS No Impact. Based on the nature of a residential land use, there is no routine transport, use or disposal of hazardous materials associated with residential uses. Therefore, there is no potential of a significant hazard associated with the project from accidents involving the release of hazardous materials into the environment, or from the emission of hazardous substances within the proximity of a school. The project site is not located within an area covered by an airport land use plan or an area where such a plan has not been adopted. However, the project site is located approximately 2.7 miles from the McClellan-Palomar Airport (public general aviation airport). The project site is not located within any flight, crash, or safety hazard zones associated with the airport. Therefore, the project will not result in a safety hazard for people residing on the project site. The project will not impair the implementation or physically interfere with any adopted emergency response plan or emergency evacuation since the project site is an infill site surrounded by urban development which is adequately served by emergency services. There are no wildlands adjacent to the site that could expose people to significant risk from wildland fires. VIII. HYDROLOGY AND WATER QUALITY-Would the project: a) No Impact. The applicant is required to comply with Order 2001-01 issued by the Regional Water Quality Control Board. A preliminary Storm Water Management Plan for the project was prepared by O’Day Consultants to address existing and proposed pollutants of concern and what measures will be implemented to ensure that pollutant loads are not increased as a result of this project, to the maximum extent practicable. Violate any water quality standards or waste discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with ground water recharge such that there would be a net deficit in aquifer volume or a lowering of the local ground water table level (i.e., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? No Impact. This project does not propose to directly draw any groundwater for potable or irrigation use. The project will be served via existing public water distribution lines adjacent to the site. The project also includes a 19 Rev. 07/03/02 detention basin. encourages water percolation back to the groundwater. The purpose of this basin is to reduce peak run-off to pre-development conditions, which c) Impacts to groundwater quality? No Impact. This project is required to implement measures to reduce urban pollutants prior to discharge, thus groundwater quality will not be affected by this project. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? No Impact. Ths project does not propose to alter existing drainage patterns, nor any stream or river that would result in erosion or siltation on or offsite. e) Substantially aIter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the flow rate or amount (volume) of surface runoff in a manner, which would result in flooding on- or off-site? Less Than Significant Impact. The project includes a detention basin on-site to reduce peak run-off to pre- development flows. f) Create or contribute runoff water, which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? No Impact. The existing storm drain system as well as the planned system as identified in the City’s Master Drainage and Storm Water Quality Management Plan will adequately convey runoff from the subject site. Since this project maintains peak runoff to predevelopment flows, there is no additional impact to consider. Compliance with NPDES requirements ensure that the off-site flow does not increase pollutant discharges. g) Otherwise substantially degrade water quality? Less than significant impact. As a result of the project: 1) Implementing source BMP measures to avoid pollutant contact and; 2) Installing treatment BMP measures to remove pollutants from storm water, this project is not anticipated to contribute additional pollutants, to the maximum extent practicable. h) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map? No Impact. The proposed project is not located within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map. Therefore there will be no impacts regarding flooding. i) Place within 100-year flood hazard area structures, which would impede or redirect flood flows? No Impact. The proposed project would not place structures within 100-year flood hazard areas. Therefore there will be no impacts from flooding. j) Expose people or structures to a significant risk of loss injury or death involving flooding, including flooding as a result of the failure of a levee or dam? k) Inundation by seiche, tsunami, or mudflow? No Impact (j & k) - According to the City of Carlsbad Geotechnical Hazards Analysis and Mapping Study, November 1992, the project site is not located within any dam failure inundation area, or area subject to inundation by seiche or tsunami. 1) Increased erosion (sediment) into receiving surface waters? 20 Rev. 07/03/02 m) Increased pollutant discharges (e.g., heavy metals, pathogens, petroleum derivatives, synthetic organics, nutrients, oxygen-demanding substances and trash) into receiving surface waters or other alteration of receiving surface water quality (e.g., temperature, dissolved oxygen or turbidity)? n) Changes to receiving water quality (marine, fresh or wetland waters) during or following construction? 0) Increase in any pollutant to an already impaired water body as listed on the Clean Water Act Section 303(d) list? p) The exceedance of applicable surface or groundwater receiving water quality objectives or degradation of beneficial uses? Less than significant impact (1, m, n, o 8z p) - The project site is not located immediately adjacent to any body of water. The project is within a watershed that ultimately drains to Batiquitos Lagoon. Batiquitos Lagoon is not listed as an impaired water body per the 303(d) list adopted February 4,2003. The project will be required to comply with Order 2001-01 and the Storm Water Management Plan for this project. Drainage and development will be controlled via best management practices to ensure that pollutants loads are not increased to the maximum extent practicable. Therefore, the project will not adversely impact water quality. IX. LAND USE AND PLANNING No Impact. The subject site is an infill site which is surrounded by multi-family residential development to the west, duplexes to the south, single-family residences to the north and a vacant lot to the east. Proposed residential development of the site will be compatible with and will integrate into the existing community. The project is consistent with the property’s General Plan designation (RMH). The density permitted on the site is 8-15 ddac, with Growth Control Management Point at 11.5 du./ac. The project’s proposed density is 11.48 ddac. The City’s Inclusionary Housing Ordinance requires that 15% of the units be reserved as affordable housing units for low income households. The project is proposing to build 9 affordable units on-site. The subject site does not conflict with any habitat conservation plans or natural communities plans in that the property is designated as an “UrbanXleveloped” area in the City’s Draft Habitat Management Plan. X. MINERAL RESOURCES No Impact. There are no known mineral resources, of local importance or otherwise, on the project site. Therefore, the proposed project would not result in the loss of availability of such resources. XI. NOISE Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance or applicable standards of other agencies? Potentially Significant Unless Mitigation Incorporated. An Acoustical Analysis report was prepared for the proposed project by Mestre Greve Associates in May 2002. The report indicates that the project site will be subject to a traffic noise level of about 66.3 CNEL from La Costa Avenue at the northern property line. In order to meet the 60 CNEL exterior noise standard, noise barriers will be required along La Costa Avenue. The barrier could be a wall, berm, or a combination of the two. The project is designed with a 5.5-foot high decorative noise attenuation wall located at the top of slope along La Costa Avenue. Also, to meet exterior noise levels for balconies located on the third floor, 5-foot high solid balcony barriers are required. Therefore, a mitigation measure has been included requiring third floor balcony noise barriers to have a density of at least 3.5 pounds per square foot with no openings and gaps. The barrier may be constructed of 318-inch plate glass, 5/8-inch plexiglass, stud and stucco construction or a combination of these materials. The interior noise levels are required to be no greater than 45 dBA CNEL. The report indicates that the buildings closest to La Costa Avenue will be exposed to noise levels of less than 60 CNEL and therefore will require less than 15 dB exterior to interior noise reduction in order to meet the standard of 45 CNEL. With construction practices common in California, residential buildings achieve outdoor to indoor noise reduction of at least 20 dB. 21 Rev. 07/03/02 b) Exposure of persons to or generation of excessive groundbourne vibration or groundbourne noise levels? No Impact - Based upon the nature of the proposed residential use, the project will not result in any activity that would generate excessive groundbourne vibration or groundbourne noise levels. In addition, the project site is not located adjacent to any use that generates excessive groundbourne vibration or groundbourne noise levels. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less than Significant Impact (c & d) - Other than traffic generated noise, typical residential land uses do not generate a substantial amount of noise. With regard to temporary or periodic increase in noise levels, the only potential increase in noise would be from construction activity associated with the development project. The City incorporates standard regulations on all project construction activity to ensure that noise and other potential impacts to surrounding properties are not significant. Therefore, the proposed project will not result in a substantial permanent or temporary increase in ambient noise levels in the project vicinity above levels existing without the project. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? No Impact (e & f) - The project site is not located within an area covered by an airport land use plan or an area where such a plan has not been adopted. However, the project site is located approximately 2.7 miles from the McClellan-Palomar Airport (public general aviation airport). The project site is not located within any flight, crash, or safety hazard zones associated with the airport. Therefore, the project will not result in a safety hazard for people residing on the project site. XI. POPULATION AND HOUSING No Impact. The project would result in the development of 58 dwelling units on an infill site surrounded by existing residential development that is served by existing roads and utilities and therefore, the project would not induce substantial growth either directly or indirectly. The project is proposed on a vacant lot and would not displace any existing housing or individuals. XIII. PUBLIC SERVICES No Impact. The project will result in 58 new dwelling units on 8.18 acres (11.48 unitdacre) which is consistent with the Growth Management Control Point of 11.5 ddac allowed on this site. The provision of public facilities within the Zone 6 LFMP, including fire & police protection, parks, libraries and other public facilities, have been planned to accommodate the projected growth in that area. Because the project will not exceed the total growth projections anticipated within the Zone 6 LFMP, all public facilities will be adequate to serve the proposed residential development on the site. Therefore, the project will not result in substantial adverse impacts to or result in the need for additional government facilities. XIV. RECREATION No Impacts. As part of the City’s Growth Management Program, a performance standard for parks was adopted. The park performance standard requires that 3 acres of Community Park and Special Use Area per 1,000 population within a park district (quadrant) must be provided. The project site is located within Park District #4 in the Southeast (SE) Quadrant. The necessary park acreage to achieve the GMP standard (3 acres/1,000 population) for Park District #4 was based upon the GMP dwelling unit limitation for the SE Quadrant, which is 17,379 units. 22 Rev. 07/03/02 The proposed project will result in 58 additional residential units in the SE Quadrant. However, those units were anticipated on this site under the City’s Growth Management Plan. The 58 proposed dwelling units on the site at a density of 1 1.48 units per acre will not exceed the growth control point (1 1.5 ddac) allowed by the site’s General Plan designation. The Parks and Recreation Element states that the park acreage demand for the SE Quadrant, based on the GMP dwelling unit limit, is 120.49 acres, and the anticipated park acreage to be provided at build-out will be 140.27 acres. Therefore, there will be adequate parkland within the SE Quadrant, and the proposed development will not cause additional demand for parkland or expansion of recreational facilities. Because park facilities will be adequate to serve residential development on the site, any increase in use of park facilities generated from development of the site will not result in substantial physical deterioration of any park facility. AM LOS INTERSECTION WITHOUT I WITH TRANSPORTATION/TRAFFIC-Would the project: PM LOS WITHOUT 1 WITH a) Cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system? La Costa Ave/El Camino Real La Costa Ave/Rancho Santa Fe Road Less Than Significant Impact. A traffic analysis was conducted for the project by Urban Systems Associates on May 16,2003 to evaluate the impacts on La Costa Avenue and impact on level of service. The project is estimated to generate 464 Average Daily Trips (ADT), 38 AM peak hour, and 47 PM peak hour trips. This project is served by La Costa Avenue, which is a secondary arterial roadway. Existing traffic on this arterial is estimated at 9,737 ADT according to the 2002 Traffic Monitoring Report. The project traffic would represent slightly more than 2% of the existing traffic on La Costa Avenue near the project, but less than 2% on other arterials in the study area. The project’s percent of the roadway design capacities are slightly more than 1% on La Costa Avenue but less than 0.5% on other arterials. While the increases in traffic from the proposed project may be slightly noticeable, the street system has been designed and sized to accommodate traffic from the project and cumulative development in the City of Carlsbad. D D D D B B C C As shown, the arterial intersections in the study area are cwrently operating acceptably and will continue to operate acceptably with project traffic added. The proposed project would not, therefore, cause an increase in traffic that is substantial in relation to existing traffic load and capacity of the street system. The impacts from the proposed project are, therefore, less than significant. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? Less Than Significant Impact. The traffic analysis conducted for the project concludes that “intersection levels of service are not expected to change as a result of project traffic, and average peak hour delays per vehicle at study area intersections are expected to be less than a two second increase, so that project impacts would be less than significant. e) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? No Impact. The proposed project does not include any aviation components. The project is located more than 2 miles from the McClellan-Palomar Airport and is not located within the boundaries of Airport Land Use Plan. It would not, therefore, result in a change of air traffic patterns or result in substantial safety risks. No impact assessed. d) Substantially increase hazards due to a design feature or incompatible uses? 23 Rev. 07/03/02 No Impact. All project circulation improvements will be designed and constructed to City standards; and, therefore, would not result in design hazards. The proposed project is consistent with the City’s general plan and zoning. Therefore, it would not increase hazards due to an incompatible use. No impact assessed. e) Result in inadequate emergency access? No Impact. The proposed project has been designed to satisfy the emergency requirements of the Fire and Police Departments. No impact assessed. f) Result in inadequate parking capacity? No Impact. The project complies with the City’s parking requirements of 2 parking spaces per unit and 17 visitor spaces to ensure an adequate parking supply. No impact assessed. g) Conflict with adopted policies, plans or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks, etc.)? No Impact. The proposed project does not conflict with adopted policies, plans, or programs supporting alternative transportation. XVI. UTILITIES AND SERVICES SYSTEMS No Impact - The proposed residential development, will be required to comply with all Regional Water Quality Control Board Requirements. In addition, the Zone 6 LFMP anticipated that the project site would be developed with a high density residential use and wastewater treatment facilities were planned and designed to accommodate future residential uses on the site. All public facilities, including water facilities, wastewater treatment facilities and drainage facilities, have been planned and designed to accommodate the growth projections for the City at build-out. The proposed density on the site will increase the demand for these facilities. However, the proposed density would not result in an overall increase in the City’s growth projection in the SE quadrant. Therefore, the project will not result in development that will result in a significant need to expand or construct new water facilitiedsupplies, wastewater treatment or storm water drainage facilities. Existing waste disposal services are adequate to serve the proposed residential use on the site without exceeding landfill capacities. In addition, the proposed residential development will be required to comply with all federal, state, and local statutes and regulations related to solid waste. MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to 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, 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? No Impact -The proposed residential project will not degrade the quality of the environment. The project site does not contain any fish or wildlife species. Therefore, the project will not reduce the habitat of a fish or wildlife species. The project site is a vacant infill site which is surrounded by existing residential development. The site is not identified by any habitat conservation plan as containing a protected, rare or endangered plant or animal community. The impact to 0.29 acres of Coastal Sage Scrub located on-site will be mitigated by acquiring mitigation credit in a pre-approved mitigation area or mitigation bank. Therefore, the project will not threaten the number of a plant or animal community. In addition, there are no historic structures on the site and there are no known cultural resources on the site. The project will not result in the elimination of any important examples of California History or prehistory. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable 24 Rev. 07/03/02 when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects?) Less than Significant Impact - San Diego Association of Governments (SANDAG) projects regional growth for the greater San Diego area, and local general plan land use policies are incorporated into SANDAG projections. Based upon those projections, region-wide standards, including storm water quality control, air quality standards, habitat conservation, congestion management standards, etc, are established to reduce the cumulative impacts of development in the region. All of the City’s development standards and regulations are consistent with the region- wide standards. The City’s standards and regulations, including grading standards, water quality and drainage standards, traffic standards, habitat and cultural resource protection regulations, and public facility standards, ensure that development within the City will not result in a significant cumulatively considerable impact. There are two regional issues that development within the City of Carlsbad has the potential to have a cumulatively considerable impact on. Those issues are air quality and regional circulation. As discussed above, the project would contribute to a cumulatively considerable potential net increase in emissions throughout the air basin. As described above, however, emissions associated with the residential development would be minimal. Given the limited emissions potentially associated with the residential development of the site, air quality would be essentially the same whether or not the residential development is implemented. According to the CEQA Guidelines Section 15130 (a)(4), the project’s contribution to the cumulative impact is considered de minimus. Any impact is assessed as less than significant. The County Congestion Management Agency (CMA) has designated three roads (Rancho Santa Fe Rd., El Camino Real and Palomar Airport Rd.) and two highway segments in Carlsbad as part of the regional circulation system. The CMA has determined, based on the City’s growth projections in the General Plan, that these designated roadways will function at acceptable levels of service in the short-term and at build-out. The project is consistent with the City’s growth projections, and therefore, the cumulative impact from the project to the regional circulation system is less than significant. With regard to any other potential impact associated with the project, City standards and regulations will ensure that residential development of the site will not result in a significant cumulatively considerable impact. c) Does the project have environmental effects, which will cause the substantial adverse effects on human beings, either directly or indirectly? Potentially Significant Unless Mitigation Incorporated - Based upon the residential nature of the project and the fact that future development of the site will comply with all City standards, the project will not result in any direct or indirect substantial adverse environmental effects on human beings. However, the project site is located in an area where human beings could be exposed to significantly high noise levels generated from traffic on adjacent roadways. As discussed above, any potential impact from noise can be mitigated to a level less than significant. Those mitigation measures will be incorporated as conditions of project approval. Any future residential development on the site will be required to comply with all applicable federal, state, regional and City regulations, which will ensure the development of the site will not result in an adverse impact on human beings, either directly or indirectly.
