STATEMENT OF OVERRIDING CONSDERATIONS 105 BEFORE THE CHULA VISTA CITY COUNCIL RE: EastLake Woods and Vistas Replanning Program; Subsequent Environmental Impact Report EIR #01-0 l, SCH #2000071019 FINDINGS OF FACT INTRODUCTION The Subsequent Environmental Impact Report (SEIR)1 prepared for this project addressed the potential environmental effects of a proposed change to existing land use plans in the EastLake Woods and Vistas neighborhoods and Panhandle site, in the 1 '030- acre EastLake 1]] General Development Plan (GDP) area, the adoption of a Sectional Planning Area (SPA) Plan with associated regulatory documents; and adoption of related amendments to the Chula Vista General Plan. In addition, the SEIR evaluated two alternatives to the proposed project: the No Project alternative, which assumes no development of the EastLake Woods, Vistas, and Panhandle sites, and the Development Consistent with the Existing GDP for EastLake alternative, which assumes implementation of the existing GDP. These findings have been prepared to comply with requirements of the California Environmental Quality Act (CEQA) (Pub. Resources Code, 21000 et seq.) and the CEQA Guidelines (Cal. Code Regs., title 14, 15000 et seq.). ] The SEIR (RECON. June 2001) incorporates previously prepared documents. including the Master EIR for EastLake (EIR 81-03). the EastLake I GDP EIR (1982). the EastLake III Olympic Training Center EIR {89-9) and Supplemental EIR (89-9), the EastLake Trails Prezone and Annexation EIR (90-12), the City of Chula Vista General Plan EIR (1989). the Salt Creek Ranch SPA Plan Final Supplemental EIR (91-03), the Otay Water District Water Resources Master Plan Final Master EIR (1996). the EastLake Trails/Greens Replanning ProFaro Final EIR (97-04), the Olympic Parkway Mitigated Negative Declaration (IS-99-20). the EastLake Business Center It Annexation Mitigated Negative Declaration (IS-00-33). and the Salt Creek Interceptor Sewer Final Program EIR (June 2001 ) by reference.

PROJECT DESCRIPTION There are five areas included in the EastLake ~I 1,030-acre GDP area: the Woods, the Vistas, a 45-acre parcel referred to as the Panhandle, the Olympic Training Center, and Business Center II. The overall purpose of the proposed EastLake llI planning progam is to amend the General Development Plan, adopt an SPA Plan and related regulatory documents for the Woods and Vistas, and process a tentative subdivision map for the Woods and Vistas. The Woods, Vistas, and Panhandle are the primary subjects of the proposed GDP amendment. The proposed amendments also require an amendment to the City of Chula Vista General Plan Land Use Element, Land Use Map, and Circulation Element. While the OTC is located within the boundaries of the GDP, it is not affected by the amendment because it is largely developed. In addition, Business Center II is proposed for transfer from the EastLake 111 GDP to the EastLake 11 GDP. The SPA Plan and conceptual tentative map only address the Woods and Vistas, and consequently this EIR provides a tentative map-level analysis only for the Woods and Vistas. The Panhandle site is analyzed at the more conceptual GDP level because no proposed SPA Plan for the property is under consideration at this time. Under the proposed GDP the Panhandle site is designated for Public/Quasi-Public use with a secondary residential use that would accommodate 90 dwelling units. The project also includes off-site improvements to Otay Lakes Road and Olympic Parkway, including widening the roadways and intersection improvements. Mitigation for these potential impacts resulting from these improvements is included in the SE1R and is discussed within these findings. The proposed amendments to the EastLake III GDP and the SPA Plan for the Woods and Vistas are described in detail below. EastLake 1121 GDP The existing and proposed EastLake ]]] GDP differ~ with respect to boundaries and densities of residential areas. conversion of open space to parkland and small portions of proposed residential areas to Retail Commercial and Tourist Commercial, and relocation of the elementary and middle school sites. Ultimately, if adopted, the proposed GDP will realize a net increase in acreage and dwelling units of low-medium and high density residential housing and a net decrease in low, medium, and medium-high density housing. Moreover, there would be a net increase in Commercial-Retail, Commercial- Tourist, and Public/Quasi-Public uses and a net decrease in Research and Limited Manufacturing, Professional Administrative, Park and Recreation, and Open Space Uses which are largely due to de-annexation of Business Center 11 and redesignation of the Panhandle site for Public/Quasi-Public use. The proposed GDP includes 650 low density DUs on 298.2 acres (2.2 du/ac), 799 low- medium density DUs on 154.5 acres (5.2 du/ac), 73 medium density DUs on 7.3 acres (10 du/ac), 239 medium high density DUs on i5.9 acres) (15 du/ac), and 300 high density DUs on 12.3 acres (24.4 du/ac). With the Panhandle site developed for Public/Quasi- Public uses, the proposed GDP would develop 2.061 dwelling units on 942 acres, for an overall average residential density of approximately 2.2 du/ac (or 4.2 du/ac within the land area designated for residential uses). With the addition of 90 low density DUs with development of the Panhandle site for residential uses, the overall residential density would be approximately 2.3 du/ac (or 4.0 du/ac within the land area desigqaated for residential uses ). Nonresidential uses in the proposed GDP include Commercial Retail (12.2 ac), Commercial Tourist (t8.4 ac), Park (15.2 ac), Public/Quasi-Public (245 ac with Panhandle site designated for P/PQ use), Open Space (137.8 ac), and Circulation (25.5 ac). 4 Proposed amendments to the existing EastLake llI GDP include: 1. Remove the 102.6-acre Business Park 1I (Research and Limited Manufacturing) area from the EastLake 1II GDP to reflect the previously approved annexation of said acreage and land use to the EastLake H GDP and EastLake I SPA; 2. Adjust the boundaries between Low and Low-Medium Density Residential land use designations to reflect a 38.4-acre reduction in the area of Low Density Residential and an increase of 97.9 acres in the Low-Medium Density Residential designation or, in the event the low density designation is applied to the Panhandle site, a 45-acre increase in Low Density Residential would occur; 3. Adjust the boundaries between the Medium and Medium-High Density Residential land use designations on the north side of Olympic Parkway to reflect a 16.6-acre reduction in Medium-High Density Residential and the addition of 12.3 acres of High Density Residential; 4. Increase the acreage of the Conunercial-Retail by 5.2 acres to a total of 12.2 acres by chan~ng the land use designation from Medium (6-11 du/ac) and Medium-High (11- 18 du/ac) Density Residential (just north of Olympic Parkway) to Commercial-Retail; 5. Modify any additional applicable land use designnations and acreage to reflect the GDP statistical modifications as shown in Table 3-1 of the SEIR; 6. Change the land use designation on the western half of the Vistas neighborhood from Low Density Residential (0-3 du/ac) to Low-Medium Density Residential (3-6 du/ac); 7. Increase the acreage of Commercial-Tourist land use designation southeast of Olympic Parkway from 14.8 to 18.4 acres; 8. Change the land use designation of the 20 acres south of Olympic Parkway betwee.n Salt Creek and the existing Olympic Training Center from Medium-High Density Residential, Professional and Administrative, and Commercial-Retail to High Density Residential ( 18-27 du/ac ) and Public/Quasi-Public; 9. Change the land use designation of 13.5 acres in the Vistas, west of Wueste Road, from Open Space to Park: 10. Modify other land use designations within the Vistas and Woods thereby reducing the overall GDP Open Space from 186.2 acres to 136.7 acres (a portion of this Open Space change results from the removal of the Open Space acreage within the EastLake Business Center II that has been deleted from the EastLake llI GDP); i 1, Change the land use designation of 15 acres located at the northeast corner of Otay Lakes Road and Hunte Parkway from Park to Public/Quasi-Public; 12. Change the middle school location to the north end of the Woods neighborhood just east of Hunte Parkway; 13. Relocate the elementary school site from the center of the Woods neighborhood to the northeast corner of Hunte Parkway and Otay Lakes Road: 14. Modify the circulation plan of the circulation element to delete the secondary collector loop road shown within the Vistas residential neighborhood. A Class I/I collector road would be added to the circulation element along the eastern portion of the Vistas neighborhood under the proposed GDP Amendment; and 15. Change the land use designation of 45 acres located in the Panhandle site from Park to Public/Quasi-Public or Low Density Residential. Approximately 90 DUs could be built under the Low Density Residential option. EastLake Woods and Vistas SPA Plan The EastLake HI SPA Plan includes both the Woods and the Vistas. (The OTC has an approved SPA Plan and the Panhandle site may be included under a separate SPA Plan in the future.) The SPA Plan defines, in more detailed terms. the development parameters of the EastLake II/GDP, including the land use mix, design criteria, primary circulation pattern, open space and recreation concept, and infrastructure requirements. The SPA Plan site utilization plan for EastLake III shows the breakdown of land uses, including housing density for the Woods and Vistas. The eastern portion of the Woods is proposed for low density housing, with 407 DUs on 216.2 acres, for an average of 1.9 du/ac. The western portion of the Woods is proposed for low-medium density housing, with 257 DUs on 43 acres, for an average of 6.0 du/ac. The Vistas is proposed for low, low-medium, medium, medium-high, and high density housing, with 1,394 DUs on 229 acres, for an average of 6.1 du/ac. The total average density of the project is 4.2 du/ac (2,061 DUs on 488.2 acres). Discretionary Actions In order to complete this replanning process, the following discretionary approvals from the City of Chula Vista are being sought by the project applicant: · Amendments to the EastLake llI General Development Plan to modify the adopted land use plan, as described above. 6 * Amendments to the EastLake H GDP, including (a) .,Mnendment to the EastLake Comrnunity Purpose Facilities Master Plan, previously adopted as part of the EastLake II GDP to incorporate the required CPF acreage for the EastLake III project and (b) Amendment to the EastLake Comprehensive Affordable Housing Program, previously adopted as part of the EastLake II GDP and Trails SPA Plan to revise the location of affordable housing sites and affordable housing requirements for the EastLake ~I project. · Adoption of the Woods and Vistas SPA Plan and associated regulatory documents for the Woods and Vistas including (a) Planned Community District Regulations, (b) Air Quality Improvement Plan, (c) Water Conservation Plan, (d) Public Facilities Financing Plan, (e) Design Guidelines, and (f) EastLake Comprehensive Affordable Housing Progam. · Amendments to the Chula Vista General Plan, including the Land Use Element and Land Use Map, and the Circulation Element. These amendments include amendment to the circulation system in the Vistas and chan~ng the designation of Olympic Parkway and Otay Lakes Road to eight- and seven-lane prime arterials, respectively, to reflect proposed modifications to the adopted GDP. · Tentative subdivision map, · Interim off-site sewer improvements. These discretionary actions are exclusive of the approval of the planned Salt Creek Interceptor. The environmental review for the discretionary approval of the Salt Creek Interceptor is discussed separately in the Final Proyam Environmental Impact Report for Salt Creek Interceptor Sewer (June 2 O0 1 ). The City of Chuta Vista is the Lead Agency and has discretionary power of approval for all the actions sought by the applicant for the proposed project. This SEIR is intended to satisfy CEQA requirements for environmental review of those actions. Future discretionary approvals may be required. No other actions by other agencies or jurisdictions have been identified that would be required to accomplish the project as proposed. Required Permits and Approvals PeNits required from the resource agencies, including a 1603 Streambed Alteration Agreement, U.S. Army Corps of Engineers (404 petmiD, a 401 waiver or authorization, and an NPDES permit from the Redonat Water Quality Control Board. A permit may be required from the U.S. Fish and Wildlife Service (section i0 of the Endangered Species Act) for impacts to the least Bell's vireo and a permit may be required from California 7 Department of Fish and Game for impacts to the Otay tarplant. A permit will not be necessary, however, if the City has a taking authorization. Project Goals and Objectives The goals and objectives of the proposed EastLake III GDP and SPA Plan project can be summarized as follows: · Assure a high quality of development consistent with city and community goals and objectives, the Chula Vista General Plan, and EastLake II/GDP. · Create an economically viable plan that can be realistically implemented within current and projected economic conditions. · Facilitate adequate provision of community facilities, such as transportation, water, flood control, sewage disposal, schools, and parks, and provide adequate assurance to the developer that approved development will be allowed in a timely and economically viable manner. · Implement and demonstrate consistency with the Chula Vista General Plan (as amended), EastLake l]l GDP (as amended), and related plans at the more detailed SPA level for Planned Community (P-C) zoning. · Provide site/project documentation showing that development will be consistent with other city policies and regulations. · Implement the housing element of the Chula Vista General Plan. · Establish a framework for subsequent construction and occupancy permitting. · Establish a land use plan that provides housing and employment opportunities for residents while maintaining an acceptable quality-of-life standard within the EastLake corm-nunity. · Control and manage redonat Fowth by establishing a phased approach to development and a Public Facilities Financing Plan which will ensure that necessary public facilities are in place at the time of need, providing for the siting and financing of such facilities. * Provide for biolo~cal mitigation opportunities within the proj ect's design. · Establish ~eenbelt and open space connections in accordance with the General Plan. · Provide uses that are compatible with and complimentary to the OTC. BACKGROUND The City of Chula Vista approved the establishment of EastLake as a planned community in 1982. The EastLake Planned Community Master EIR (#81-03) was prepared in February 1982. and the EastLake General Plan Amendment, including the EastLake I General Development Plan, was adopted in August 1982. Following the preparation of the original EIR for the EastLake I GDP, subsequent EIRs have been prepared for GDP Amendments and Sectional Planning Area Plans within EastLake I, II, and 11I (Olympic Training Center). The existing EastLake Hl GDP was approved in 1990. The Final EIR (#89-9) for EastLake 111, Olympic Training Center was prepared in October 1989 and included the SPA Plan for the OTC. It also included the GDP for all of EastLake III as well as a proposal to annex EastLake llI and the Trails (EastLake H) from the unincorporated area of San Diego County into the City of Chula Vista. The original GDP for EastLake llI proposed a mixed-use development with residential, industrial, commercial, public-quasi public, parks and recreation, and open space uses. At that time, the EastLake III GDP project was determined to have cumulatively significant impacts that could not be fully mitigated for public services and utilities (water supply, sewer treatment capacity, and nonrenewable energy resources), visual resources (views from surrounding areas), and air quality (primarily from automobile emissions). Other impacts were determined to be below a level of sigTdficance either prior to or after implementation of mitigation measures. RECORD OF PROCEEDINGS For purposes of CEQA and the findings set forth below, the administrative record of the City Council decision on the environmental analysis of this project shall consist of the following: · The Notice of Preparation and all other public notices issued by the City in conjunction with the project: The Draft and Final Subsequent EIR for the project (EIR #01-01), including appendixes and technical reports; · All reports. applications, memoranda, maps, letters, and other planning documents prepared by the planning consultant. the project applicant, the environmental 9 consultant, the EastLake Company, and the City of Chula Vista that are before the decisionmakers as determined by the City Clerk; · All documents and comments and correspondence submitted by members of the public and public agencies in connection with this project, in addition to comments on the EIR for the project; * All documents submitted to the City by other public agencies or members of the public in connection with this project, up through the close of the public hearing on July 27, 2001. · Minutes and verbatim transcripts of all workshops, public meetings, and public hearings held by the City of Chula Vista. or videotapes where transcripts are not available or adequate, with respect to this project or the EIR for the project; · Any documentary or other evidence submitted at workshops, public meetings, and public hearings for this project; · All findings and resolutions adopted by City decisionmakers in connection with this project, and all documents cited or referred to therein; · Matters of common knowledge to the City of Chula Vista which the members of the City Council consider regarding this project, including federal, state, and local laws and regulations, and including but not Iimited to the following: - Chula Vista General Plan - Relevant portions of the Zoning Codes of the City of Chula Vista - Final EastLake Planned Community Master EIR (El:R 81-3) - EastLake llFOlympic Training Center Final EIR (89-9) - EastLake Trails/Greens Replanning ProFaro, Final SEIR (97-04); and Any other materials required to be in the record of proceedings by Public Resources Code section 21167.6, subdivision (e). The custodian of the documents comprising the record of proceedings is Susan Bigelow, Clerk to the City Council, whose office is located at 276 Fourth Avenue, Chula Vista, California, 9 1910. 10 The City Council has relied on all of the documents listed above in reaching its decision on the EastLake Woods and Vistas Replanning ProFam, even if not every document was formally presented to the City Council or City Staff as pan of the City files generated in connection with the EastLake Woods and Vistas Replanning Pro~am. Without exception, any documents set forth above not found in the project files fall into one of two categories. Many of them reflect prior planning or le~slative decisions with which the City Council was aware in approving the EastLake Woods and Vistas Replanning Program. (See Ci.ty of Santa Cruz v. Local Agency Forenation Commission (1978) 76 Cal. App.3d 381, 391-392 [142 Cal.Rptr. 873]; Dominey v. Department of Personnel Administration (1988) 205 Cal.App.3d 729, 738, fn. 6 [252 Cal.Rptr. 620].) Other documents influenced the expert advice provided to City Staff or consultants, who then provided advice to the City Council. For that reason, such documents form pan of the underlying factual basis for the City Council's decisions relating to the adoption of EastLake Woods and Vistas Replanning Pro~am. (See Pub. Resources Code, section 21167.6, subd. (e)(10); Browning-Ferris h~dustries v. CiO, Council qf Cit3., of San Jose (1986) 181 Cal. App.3d 852, 866 [226 Cal.Rptr. 575]; Stanislaus Audubon Socie.ry, bic. v. Coun~ of Stanislaus (1995) 33 Cal. App.4th 144, 153, 155 [39 Cal.Rptr.2d 54].) VI. FINDINGS REQUIRED UNDER CEQA Public Resources Code section 21002 provides that "public agencies should not approve projects as proposed if there are feasible alternatives or feasible mitigation measures available which would substantially lessen the significant environmental effects of such projects[.]" (Emphasis added.) The same statute states that the procedures required by CEQA "are intended to assist public agencies in systematically identifying both the si~,mificant effects of proposed projects and the feasible alternatives or feasible mitigation measures which will avoid or substantially lessen such significant effects." (Emphasis added.) Section 21002 goes on to state that "in the event [that] specific economic, social, or other conditions make infeasible such project alternatives or such mitigation measures, individual projects may be approved in spite of one or more significant effects." The mandate and principles announced in Public Resources Code section 21002 are implemented, in pan, through the requirement that agencies must adopt findings before approving projects for which EIRs are required. (See Pub. Resources Code, section 21081, sub& (a); CEQA Guidelines, section 15091, subd. (a).) For each significant environmental effect identified in an EIR for a proposed project, the approving agency must issue a written finding reaching one or more of three permissible conclusions. The first such finding is that "[c]hanges or alterations have been required in, or incorporated into. the project which avoid or substantially lessen the significant environmental effect 11 as identified in the final EIR."/CEQA Guidelines, section 15091, subd. (a)(1).) The ' second permissible finding is that "[s]uch changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency." (CEQA Guidelines, section 15091, subd. (a)(2).) The third potential conclusion is that "[s]peci~c economic, legal, social, technological, or other considerations, including provision of employment opportunities for highl3~ trained workers, make infeasible the mitigation measures or project alternatives identified in the final EIR." (CEQA Guidelines, section 15091, subd. (a)(3).) Public Resources Code section 21061.1 defines "feasible" to mean "capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social and technolo~cal factors." CEQA-Guidelines section 15364 adds another factor: "legal" considerations. (See also Citiz. ens of Goleta Valley v. Board of Supen, isors CGoleta It') (1990) 52 Cal.3d 553,565 [276 Cal.RplT. 410].) The concept of "feasibility" also encompasses the question of whether a particular alternative or mitigation measure promotes the underlying goals and objectives of a project. (City of Del Mar v. City of San Diego (1982) 133 Cal.App.3d 410, 417 [183 Cal.Rptr. 898].) "'[F]easibility' under CEQA encompasses 'desirability' to the extent that desirability is based on a reasonable balancing of the relevant economic, environmental, social, and technolo~cal factors." (Ibid.; see also Sequoyah Hills Homeowners Assn. v. City of Oakland (1993) 23 Cal.App.4th 704, 715 [29 Cal. Rptr.2d 182].) The CEQA Guidelines do not define the difference between "avoiding" a significant environmental effect and merely "substantially lessening" such an effect. The City must therefore glean the meaning of these terms from the other contexts in which the terms are used. Public Resources Code section 21081, on which CEQA Guidelines section 15091 is based, uses the term "mitigate" rather than "substantially lessen." The CEQA Guidelines therefore equate "mitigating" with "substantially lessening." Such an understanding of the statutory term is consistent with the policies underlying CEQA, which include the policy that "public agencies should not approve projects as proposed if there are feasible alternatives or feasible mitigation measures available which would substantially lessen the significant environmental effects of such projects." (Pub. Resources Code. section 21002. ) For purposes of these findings, the term "avoid" refers to the effectiveness of one or more mitigation measures to reduce an otherwise significant effect to a less than significant level. In contrast, the term "substantially lessen" refers to the effectiveness of such measure or measures to substantially reduce the severity of a significant effect, but not to reduce that effect to a less than significant level. These interpretations appear to be mandated by the holding in Laurel Hills Homeowners Association v. City Council (1978) 83 Cal.App.3d 515, 519~527 [147 Cal.Rptr. 842], in which the Court of Appeal held that an agency had satisfied its obligation to substantially lessen or avoid significant effects by adopting numerous mitigation measures, not all of which rendered the significant impacts in question (e.g., the "m~onal traffic problem") less than significant. Although CEQA Guidelines section 15091 requires only that approving agencies specify that a particular significant effect is "avoid[ed] or substantially lessen[ed]," these findings, for purposes of clarity, in each case will specify whether the effect in question has been reduced to a less than significant level, or has simply been substantially lessened but remains significant. Moreover, although section 15091, read literally, does not require findings to address environmental effects that an EIR identifies as merely "potentially significant," these findings will nevertheless fully account for all such effects identified in the Final EIR. In short, CEQA requires that the lead agency adopt mitigation measures or alternatives, where feasible, to substantially lessen or avoid significant environmental impacts that would otherwise occur. Project modification or alternatives are not required, however, where such changes are infeasible or where the responsibility for modifying the project lies with some other agency. (CEQA Guidelines, section 15091, subd. (a), (b).) With respect to a project for which significant impacts are not avoided or substantially lessened either through the adoption of feasible mitigation measures or feasible environmentally superior alternative, a public agency, after adopting proper findings, may nevertheless approve the project if the agency first adopts a statement of overriding considerations setting forth the specific reasons why the agency found that the project's "benefits" rendered "acceptable" its "unavoidable adverse environmental effects." (CEQA Guidelines, sections 15093, 15043, subd. (b); see also Pub. Resources Code, section 21081, subd. (b).) The California Supreme Court has stated that "[t]he wisdom of approving . . . any development project, a delicate task which requires a balancing of interests, is necessarily left to the sound discretion of the local officials and their constituents who are responsible for such decisions. The law as we interpret and apply it simply requires that those decisions be informed, and therefore balanced." (Goleta II, 52 Cal.3d 553,576.) VII. LEGAL EPI~ECT OF FINDINGS To the extent that these findings conclude that proposed mitigation measures outlined in the SEIR are feasible and have not been modified, superseded or withdrawn, the City of Chula Vista ("City" or "decisionmakers") hereby binds itself and any other responsible 13 parties, including the applicant and its successors in interest (hereinafter referred to as "' "Applicant"), to implement those measures. These findings, in other words, are not merely informational or hortatory, but constitute a binding set of obligations that will come into effect when the City adopts the resolution(s) approving the project. The adopted mitigation measures are express conditions of approval. Other requirements are referenced in the mitigation monitoring reporting program adopted concurrently with these findings. and will be effectuated through the process of implementing the project. VHI. MITIGATION MONITORING PROGRAM As required by Public Resources Code section 21081.6, subd. (a)(1), the City of Chula Vista, in adopting these findings, also adopts a mitigation monitoring and reporting program (MMRP) as prepared by the environmental consultant under the direction of the City. The program is designed to ensure that during project implementation, the applicant and any other responsible parties comply with the feasible mitigation measures identified below. The program is described in the document entitled EastLake Woods ._. and Vistas Replanning Program Mitigation Monitoring Reporting Program. The MMRP will remain available for public review during the compliance period. SIGNIFICANT EPHzCTS AND MITIGATION MEASURES The Subsequent EIR identified a number of direct and indirect significant environmental effects (or "impacts") that the project will cause; some can be fully avoided through the adoption of feasible mitigation measures, while others cannot be avoided. The project will result in sig'ni~cant irreversible environmental changes to the following issues: land use, transportation/traffic, biolo~cal resources, hydrology/drainage, landfog alteration/visual quality, geology/geolo~c hazards, noise, air quality. cultural/ paleontolo~4cal resources, and public facilities. These significant environmental changes or impacts are discussed in Subsequent EIR 01-01 in Table 1-3 on pages 9-54 and in Chapter 4.0, pages 97-416. The SEIR also discusses the Panhandle site at the more conceptual, progarnmatic GDP " level under a separate subheading because no proposed SPA Plan for the property is under consideration at this time and the specific uses of the site are not yet known. As 14 such, future plans and applications to develop the Panhandle site will be subject to a more comprehensive CEQA review and will be subject to further. more specific mitigation measures as necessary. These Findings of Fact maintain that format and discuss the Panhandle site under a separate heading in the following discussions. Land Use Panhandle Site Significant land use impacts may result at the time development plans are proposed resulting from potential inconsistencies with the goals and objectives of the Eastern Territories Area Plan and MSCP Subarea Plan. Transportation/Traffic Woods and Vistas Direct project impacts to roadways would occur on Olympic Parkway from SR-125 to Hunte Parkway and on Otay Lakes Road from H Street to Telegaph Canyon Road. Planned activity centers in the Woods and Vistas may be associated with access hazards or circulation impediments. An analysis was conducted of the three access points to the Woods and the Ol.vmpic Parkway and Otay Lakes Road access points to the Vistas. Assuming the driveways are unsignalized, four of the five driveways are calculated to operate at LOS F. Panhandle Site Traffic generated by future development may significantly impact the circulation system. SecondaD' Impacts Associated with Off-Site D'affic Mitigation Improvements The off-site traffic improvements could create secondary impacts associated with land use, biological resources, construction-related water quality impacts, construction-related traffic impacts (potential closures, traffic delays, and hazards), aesthetics/landform alteration, noise, and culturalJpaleontolo~cal resources. Biolo~cal Resources -.. Woods and lqstas Development of the EastLake III project site would impact disturbed Diegan coastal sage scrub, non-native Fassland, southern willow scrub, mule fat scrub, disturbed wetland, and freshwater marsh. Additional impacts could occur to disturbed habitat, ornamental vegetation, and non-wetland jurisdictional waters of the U.S. for the off-site improvements to Otay Lakes Road, east of the Woods parcel. Development of the EastLake HI project site would impact '32 Otay tarplants and construction activities could result in significant impacts to raptors. Impacts from construction noise to least Bell's vireo would also be significant. Indirect impacts may occur on the City of San Diego "Cornerstone Lands" and the Chula Vista MSCP preserve lands adjacent to the project site. Panhandle Site Development of the Panhandle site may cause significant impacts to existing biolo~cal resources on- and off-site, including disturbed coastal sage scrub, non-weftand jurisdictional waters and potential weftands (i.e., vernal pools). Indirect impacts may occur on the City of San Diego "Cornerstone Lands" and the Chula Vista MSCP preserve lands adjacent to the project site. Hvdrolo~v/Dralnage Woods and Vistas Under the developed site conditions, potentially significant water quality impacts could result from ranoff flowing across impervious surfaces as well as landscaped areas containing pollutants. Additional impacts to water quality may result from the use of reclaimed water for on-site irrigation of parks and nonresidential landscape. In order to avoid impacts to the Otay Reservoirs and potable water supplies the project proposes to divert surface flows from approximately 243 acres to the Salt Creek Basin. Approximately 60.4 acres of undisturbed natural open space and landscaped, manufactured slopes within the Woods and Vistas would continue to drain into Otay Reservoirs. The vegetation used in landscaping of the manufactured slope will serve as a natural filter for the limited quantity of ranoff to the reservoirs. The vegetation will be drought tolerant, the majority of which will be native. Pesticides and fertilizers would not be used on these slopes to further protect the water quality of the reservoirs I6 Development of the proposed project could cause an increase in the amount of runoff and have potentially significant hydrolo~c impacts on downstream drainage facilities during the t00-year, 50-year, and 10-year storm events. in addition, the proposed diversion from the Vistas neighborhood may exceed the capacity of the existing Olympic Parkway storm drain system, which would be a significant impact if storm water ranoff is not directed beyond the Olympic Parkway system to the existing Salt Creek outfall(s) located on-site. Groundwater seepage, if detected in site-specific testing once development plans have been finalized, could create a significant impact. Panhandle Site Future development could cause an increase in the amount of runoff and have potentially sigTdficant impacts on downstream drainage facilities. Groundwater seepage, if detected in site-specific testing once development plans have been finalized, could create a significant impact on the Panhandle site. Landform Alteration/Visual Quality Woods and Vistas The proposed development would alter existing landforms and the visual characteristics of the site through grading, excavation of the ridge tops~ and in-filling of canyons. Open expanses of rolling hills used for agricultural purposes would be developed with residential, public/quasi-public, and commercial areas separated by open space. Panhandle Site Development of the Panhandle site, depending on the proposed use, may significantly impact the existing landforms and visual characteristics of the site as well as affect views from surrounding areas. Geolo~v/Geolo_,zic Hazards Woods and Vistas Significant impacts could result from development on compressible and expansive soils. The highly expansive nature of Diablo clays, which predominate on the project site, makes them unsuitable for foundation supports. Alluvial and colluvial deposits in the drainage courses could undergo liquefaction. 17 Unstable conditions may result from grading in axeas with cut or underlying fill slopes. Slope faces associated with clay beds may also become unstable due to an increased potential for seepage caused by migration of perched groundwater. Panhandle Site Significant impacts could result from project development on compressible and expansive soils if further investigation determines their presence on-site. Potential impacts could also result from geologic hazards. Noise Woods and Vistas Traffic on Mc!jor Roadways The proposed project would be affected by traffic noise generated on Otay Lakes Road, a portion of Hunte Parkway, and Olympic Parkway. The traffic on these streets could generate noise levels ~eater than 65 CNEL, which is the City's residential exterior standard, at ~ound-level sensitive receivers on a limited portion of the project site. Construction Noise If least Bell's vireo axe present in the habitat north of Otay Lakes Road during project construction, excessive construction noise (60 decibels or more) at any least Bell's vireo nest site during the breeding season would be considered a significant impact. Traffic on b~ten~al Roadways interior noise levels at the residential pads adjacent to Street "P" within the Vistas site could exceed the City's 45 CNEL residential interior noise standard resulting in a significant noise impact. Noise Generated By Non-Residential Uses Because the specific uses are not 'known, development of the commercial areas could result in significant noise impacts if those uses were to violate the Noise Ordinance. Panhandle Site Significant noise impacts from construction, project operations, and/or traffic-related noise could result if the Panhandle site is developed for public/quasi-public use or low density residential uses. 18 Air Quality Woods and Vistas Cot!fozTnance with Regional Plans The project is not consistent with the ~owth assumptions in the RAQS, and therefore, the proposed project is not consistent with the goals and objectives of the RAQS. Implementation of the proposed project could therefore result in significant air emissions to the air basin that are not currently planned for. Project Operations Emissions Project operations-related emissions, including those from stationary and mobile sources, are projected to exceed SCAQMD thresholds. Construction Emissions The construction of the proposed project would result in the generation of construction equipment exhaust emissions, potentially resulting in a significant air quality impact. Construction activities are projected to generate sufficient quantities of fugitive dust to create a significant impact. Panhandle Site Construction on the Panhandle site and project operations could significanfiy impact air quality depending on the proposed land use. Cultural Resources Woods and Vistas The proposed development of the Woods parcel would result in direct and indirect impacts to CA-SDI-7976. Panhandle Site The four lithic scatter sites at the Panhandle have not been evaluated for cultural resource si~oTdficance under CEQA, and therefore the impact is considered significant. Paleontolo,oical Resources Woods and Vistas Areas of the Otay Formation may be exposed during grading and construction activities. Exposure of this formation would likely disturb fossil remains in the Vistas and Woods. Panhandle Site Areas of the Otay Formation may be exposed during grading and construction activities. Exposure of this formation would likely disturb fossil remains in the Panhandle site. Public Facilities POTABLE WATER lA'bods and Vistas The proposed project places additional demands on water storage and pumping facilities, which could be significant if construction of new facilities does not coincide with the project' s anticipated growth ..... - Panhandle Site Development of the Panhandle site would result in an incremental increase in water demand, thereby potentially impacting water storage and conveyance facilities. RECYCLED VVATER Woods and Vistas The proposed project places additional demands on water storage and pumping facilities, which could be significant if construction of new facilities does not coincide with the project' s anticipated growth. Panhandle Site Development of the Panhandle site would incrementally increase the demand for recycled water, thereby potentially impacting recycled water storage and conveyance facilities. 2O SE~qER Woods and Vistas Development of the proposed project would result in an incremental increase in sewage generation. This increase could cause a significant impact if construction of new infrastructure does not coincide with the project's anticipated development. If the Salt Creek Interceptor is not completed prior to consideration of the tentative map, wastewater shall be temporarily pumped to facilities in Telegaph Canyon and/or Pog~ Canyon. Panhandle Site Wastewater generation from development of the Panhandle site would require conveyance facilities and potentially impact the City's sewer system and treatment capacity. PARKS AND RECREATION Panhandle Site If the Panhandle site is developed with low density residential uses. potentially significant impacts to park and recreation facilities could occur. POLICE Woods and Vistas The project would cause an incremental increase in calls for police services and contribute to an increase in response time for the Chula Vista Police Department. Panhandle Site Development of the Panhandle site could cause an incremental increase in calls for police services and contribute to an increase in response time for the Chula Vista Police Department. FIE Woods and Vistas The project would increase the demand for fire services and could contribute to an increase in response time for the Fire Department. 21 ParThandle Site The project would increase the demand for fire services and could contribute to an increase in response time for the Fire Department. The majority of the impacts presented above can be reduced below a level of significance with the mitigation measures described in the SEIR and below. However, certain of the impacts cannot be substantially lessened or avoided with mitigation; but, as described in the Statement of Overriding Considerations, the City Council has determined that the impacts are acceptable because of specific overriding considerations. The following subsections describe specific impacts, setting forth the reasons why they are significant and where applicable, unavoidable, the mitigation measures, and/or why the mitigation measures proved to be infeasible due to specific economic, social, or other considerations. All page numbers following the impacts refer to pages from the SEIR. A. LAND USE Standards of Significance: A significant land use impact is identified if the project could: · Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project; · Directly conflict with existing or planned land use; · Physically divide an established community; · Remove existing community elements that have been identified by the community as important in defining community character; or · Conflict with any applicable habitat conservation plan or natural communities conservation plan Impact: · There is the potential for significant land use impacts at the time development plans are proposed for the Panhandle site because consistency with city and redohal plans is based on future compliance with the goals and objectives of these plans. [SEIR, Subchapter 4.1, pp. 118-119] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen 22 or avoid the significant environmental effect as identified in the SEIR, below a level of significance. Explanation: Implementation of the project would result in the conversion of undeveloped land, currently designated as Park and Recreation, from that historically used for agricultural production to that desi~ated as a Public/Quasi-Public use area or, in the alternative, Low Density Residential use. The specific uses of the 45-acre site have not been finally proposed, although it may be included in the future "University SPA" or it may be developed with up to 90 single-family dwellings. It is anticipated that development of the Panhandle site under either designation wilt be consistent with the policies and guidelines in both the Eastern Territories Area Plan and the Chula Vista Multiple Species Conservation Program Subarea Plan. However, because it is premature to prepare detailed development plans for the Panhandle, the land use re-designation is considered a program level action. Accordingly, it is necessary to establish mandatory performance criteria to ensure that future planning of the Panhandle at the project level will not result in conflicts with or si~-mificant impacts to the Eastern Territories Area Plan and MSCP. [See discussion in SEIR, Section 4.1, pp. 118-119.] Mitigation Measure: The following mitigation measure is feasible and is required as a condition of approval and is made binding on the applicant through these findings. [SEER, Subchapter 4.1, page 120] 4.1.5.1 At the time detailed development plans are proposed for the Panhandle site, conformance with adopted goals and objectives of the Eastern Territories Area Plan and MSCP Subarea Plan shall be required as a condition of project approval. Significance After Mitigation: Less than significant B. TRANSPORTATION/TRAFFIC Standards of Significance: Near-Term (Study Horizon Year 0-4/Pre-Year 2005) Intersections A) Significant direct project impact results if both the following criteria are met: 1 ) LOS E or LOS F. 2) Project trips comprise 5 percent or more of entering volume. 23 B ) Cumulative impact results if only #1 is met. Street Segments If ADT methodology indicates acceptable LOS C or better conditions, there is no impact. If ADT methodology indicates LOS D, E, or F, the Growth Management Oversight Committee method should be utilized according to the following criteria. A) Significant direct project impact results if the following criteria are met: 1 ) LOS D for more than 2 hours or LOS E/F for 1 hour. 2) Project trips compromise 5% or more of segment volume. 3) Project adds ~eater than 800 ADT to segments. B ) Si~i~cant cumulative impact results if only #i is met. Freeways A) Significant direct project impact results if both the following criteria are met: 1 ) LOS E or LOS F. 2) Project constitutes 5 percent or more of the total forecasted ADT on that freeway segment. B ) Sig-nificant cumulative impact results if only #1 is met. Long-Term (Year 2005 and Later) bitersections Direct project impact if both the following criteria are met: 1 ) LOS E or LOS F. 2) Project trips comprise 5% or more of entering volume. B) Cumulative impact is only #1 is met. Street Segments Use the ADT methodology. 24 A) Direct project impact results if all three of the following criteria are met: 1 ) LOS D, LOS E, or LOS F. 2) Project trips comprise 5 percent or more of total segment volume. 3) Project adds ~eater than 800 ADT to the seg'ment. B/ Cumulative impact results if only #t is met. However. if the intersections along a LOS D or E operating segment all operate at LOS D or better, the segment impact is considered not significant because intersection analysis is more indicative of actual roadway system operations than street segment analysis. ff the segment level of service is LOS F, the impact is significant regardless of the intersection LOS. The impact is direct if the project is responsible for over 5 percent of U'affic contribution and the impact is cumulative if the project is responsible for less than 5 percent of traffic contribution. C) Notwithstanding the foregoing, if the impact identified in "A" above occurs at study horizon year 10 or later, and is off-site and not adjacent to the project, the impact is considered cumulative. D) In the event a direct identified project specific impact in "A" above occurs at study horizon year 5 or earlier and the impact is off-site and not adjacent to this project, but the property immediately adjacent to the project specific impact is also proposed to be developed in approximately the same time frame, an additional analysis may be required to determine whether or not the project- specific impact would still occur if the development of the adjacent property does not occur. If the additional analysis concludes that the project specific impact is no longer a direct impact, then the impact shall be considered cumulative. Freeways A) Direct project impact if both the following criteria are met: 1 ) LOS E or LOS F. 2) Project comprises 5% or more of the total forecasted ADT on that freeway se~'nent. B) Cumulative impact if only #1 is met. 25 Impact: ·Direct project impacts to roadways would occur on Olympic Parkway from SR~ 125 to Hunte Parkway. [SEIR, Subchapter 4.2, pp. 161.169] Finding: Pursuant to section 15091(a)(i) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR, below a level of si~ificance. Explanation: The street segment was assessed by comparing the current street segment volume to the theoretical capacity (v/c) of the roadway. Olympic Parkway from SR-125 to Hunte Parkway will operate at LOS F for one or more hours as a result of project traffic. In addition, project trips will compromise 5% or 'more of segment volume and the project adds ~eater than 800 ADT to the se~mnent. (The total external trip generation for the Woods and Vistas under the proposed land uses yields 23.940 average daily trips (ADT)). Widening this segment of Olympic Parkway to six lanes would accommodate the additional project traffic volume. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, page 204] 4.2.5.1 The applicant shall construct this portion of the Olympic Parkway to six- lane prime arterial standards at the time the first project dwelling unit is constructed. Significance After Mitigation: Less than significant Impact: · Direct project impacts to roadways would occur on Otay Lakes Road from H SWeet to Telegaph Canyon Road. [SEIR, Subchapter 4.2, pp. 161,169] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the sig-nificant environmental effect as identified in the SEIR, below a level of sigmificance. Explanation: The street segment was assessed by comparing the current street segrnent volume to the theoretical capacity of the roadway. Otay Lakes Road from H Street to Telegraph Canyon Road will operate at LOS D for two or more hours and LOS E and F for one or more hours as a result of project traffic. In addition, project trips will 26 compromise 5% or more of segment volume and the project adds geater than 800 ADT to the segment. (The total external trip generation for the Woods and Vistas under the proposed land uses yields 23,940 ADT.) Widening this portion of Otay Lakes Road or constructing intersection improvements would accommodate project traffic x'olume. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, page 204] 4.2.5.2ff development exceeds 1,259 dwelling units without SR-125, the applicant shall widen this portion of Otay Lakes Road to six lanes or construct intersection improvements on Otay Lakes Road, which provides additional capacity to the satisfaction of the City Engineer Significance After Mitigation: Less than significant Impact: · Planned activity centers in the Woods and Vistas, such as the elementary and middle schools, park and recreation areas, and the commercial district, may experience access hazards or circulation impediments. These conditions could pose significant traffic impacts. [SEll>,, Subchapter 4.2, pp. 195-196] Finding: Pursuant to section 15091(a)(1 ) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: The proposed project includes several uses that may result in site-specific traffic and circulation issues: two schools (elementary and middle school), a public park, a private recreation area, a community purpose facility (which may support baseball fields), and the retail and tourist commercial uses in the southern portion of the Vistas. Because site plans have not been drafted for any of these uses, site-specific impacts cannot be determined at this time. Potential impacts that are common to these types of uses, however, can be anticipated and site planning can minimize these potential impacts. Traffic and circulation issues associated with elementary and middle schools relate to student pick-up/drop-off, parking, and vehicle and pedestrian access. Park and recreation areas also need sufficient parking and safe access. The primary traffic concerns pertaining to commercial areas are safe and efficient vehicle access from the street, and protection of shoppers traveling via alternative transportation modes. 27 Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, pp. 205-206]. Revisions to mitigation measures 4.2.5.10 and 4.2.5.11, which strengthen the effectiveness of the measures by adding performance standards, are reflected in replacement pages for the Final SEIR and MMRP. 4.2.5.10 All non-residential projects (with the exception of schools) shall comply with the City's GMOC standards and other applicable traffic policies and standards. The City En~neer shall review all site plans for nonresidential uses, (with the exception of schools), and require a project-specific traffic study if the project has the potential for resulting in traffic hazards or circulation impacts. Recommendations to reduce potentially si~nificant impacts, pursuant to the GMOC standards and City traffic standards and policies, shall be incorporated into the site plan and required as a condition of project approval. 4.2.5.11 Potential traffic impacts resulting from development and operation of the schools shall be reviewed by the respective school districts when specific projects are under consideration. Any street improvements shall be coordinated with the City and shall comply with applicable City street standards and policies. The City shall request review of all draft plans. Significance After Mitigation: Less than sig-nificant Impact: An analysis was conducted of the three access points to the WoOds (one each on Proctor Valley Road. Hunte Parkway, and Otay Lakes Road) and the Olympic Parkway and Otay Lakes Road access points to the Vistas. Assuming the driveways are unsignalized, four of the five driveways are calculated to operate at LOS F, which is considered a significant impact. [SEIR, Subchapter 4.2, page 197] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: The project includes five access points from existing or future roads. As indicated in the PFFP, some of the access points are necessary to provide adequate traffic circulation in and out of the project. The Proctor Valley Road access point, however, will serve as a convenience only because Proctor Valley Road is not required by this project for either congestion management nor for access by emergency services. Therefore, the 28 access point will be installed only if and when Proctor Valley Road is constructed as required by other projects. The preliminary traffic analysis demonstrated that four of these five access points would suffer less than acceptable levels of service if the intersections at those planned access points are not signalized and fail to include turning lanes. A preliminary review of forecasted traffic volumes for the project access points indicate that single left-turn lanes could be provided to in~ess each access point and single left-turn and right-turn lanes could be provided to e~ess each access point. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, page 206] Revisions to mitigation measures 4.2.5.12, 4.2.5.13, and 4.2.5.14, which clarify application of the mitigation, are reflected in replacement pages for the Final SEIR and MMRP. 4.2.5.12 Prior to approval of the first final map, which triggers the installation of the related street improvements, the applicant shall enter into an a~eement to construct and secure a fully activated traffic signal including interconnected wiring at the following intersections: a) Proctor Valley Road and Woods Entry Street (between WR-1 and WR-3) (Note: EastLake will pay for the construction of Proctor Valley Road improvements, along the frontage of the project extending from the weste~y subdivision boundary to Northwoods Drive, and the City may use the payment as the City deems appropriate to acquire completed portions and/or pay directly for the construction of the Proctor Valley Road improvements. ) b) Hunte Parkway and Woods Entry (between WR-6 and WR-7) c) Hunte Parkway and Woods Entry Street (between PQ-2 and WR- 4) d) Otay Lakes Road and Woods Entry Street (adjacent to PQ-3) e) Otay Lakes Road and Vistas Entry Street (between VR-1 and VR- 5) f) Otay Lakes Road and Wueste Road g) Olympic Parkway and Vistas Entry Street (between VR-4 and VR- 10) h) Olympic Parkway and Wueste Road (adjacent to C-2) 29 i) Wueste Road and Vistas Entry Road (adjacent to Park P-1 ) 4.2.5.13 With the exception of the Proctor Valley Road access point, the applicant shall fully design the aforementioned traffic signals in conjunction with the improvement plans for the related street. The developer shall install under~ound improvements, standards and luminaries in conjunction with the construction of the applicable street improvements. In addition, the applicant shall install mast arms, signal heads, and associated equipment when traffic signals warrant as determined by the City Engineer. 4.2.5.14 The applicant shall provide single lefi-tum lanes to in~ess each access point, with the exception of the Proctor Valley Road access point, and single left- and right-turn lanes shall b~ provided to egress each access point. Significance After Mitigation: Less than significant Panhandle Site Impact: Traffic generated by future development may significantly impact the circulation system. [SEIR, Subchapter 4.2, page 199] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~onificant environmental effect as identified in the SEIR, to below a level of sigrdficance. Ex~planation: Development of the Panhandle site is expected to generate traffic, with volume being dependent on its final designatiofi for public/quasi-public or residential use. Increased traffic will affect the surrounding circulation system and requires additional analysis. The trip generation associated with the 90-unit residential use project would generate approximately 900 ADT. The trip generation associated with Public/Quasi- Public uses would be approximately 2,700 ADT based on a trip rate of 60 ADT per acre. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, page 207] 4.2.5.15 Prior to the approval of any detailed development plans for the Panhandle site, a detailed traffic study shall be conducted, including a 3O detailed impact analysis. Specific mitigation measures for traffic impacts associated with the Panhandle site shall be required at that time to the satisfaction of the City Engineer, including any improvements related to any necessary roadway segments, intersections, and ingress- egress to reduce impacts to below a level of significance and to comply with the City's GMOC standards. Significance After Mitigation: Less than significant Seconda~3' Impacts Associated with Off-Site Traffic Mitigation Improvements Impact: · The off-site traffic improvements to Olympic Parkway and Otay Lakes Road could create secondary impacts associated with land use, biological resources, construction-related water quality impacts, construction-related traffic impacts (potential land closures, traffic delays, and hazards), aesthetics/landform alteration, noise, and culturalJpaleontological resoumes. [SEIR, Subchapter 4.2, pp. 207-209] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: The off-site traffic improvements for direct and cumulative traffic impacts could create secondary impacts associated with land use, biological resources, construction-related water quality impacts, construction-related traffic impacts (potential land closures, traffic delays, and hazards), aesthetics/landform alteration, noise, and cultural/paleontological resources. Off-site improvements, including road widening could create landform alteration impacts and increased noise impacts for the existing uses~ especially houses with frontage on the roadway by placing the noise source closer to the homes. In addition, grading to widen the roadways could create impacts to culmral/paleontological resources and construction-related water quality and traffic impacts. Although these off-site roadway improvements have not been designed or engineered, program-level mitigation requirements are identified below to reduce the impacts to below a level of significance at the time the improvements are designed. Depending on the detailed design of the off-site traffic improvements additional environmental review may be required. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, pp. 209-2 i0] 3i The proFaro-level mitigation measures include the following: 4.2.5.16 Prior to the approval of the roadway improvement project, a biolo~cal reconnaissance based on detailed grading and design plans shall be conducted to document any impacts to sensitive biological habitats and species. Any impacts to sensitive biolo~cal habitats shall be mitigated pursuant to the mitigation ratios described in the City of Chula Vista Subarea Plan. 4.2.5.17 Prior to the issuance of any grading permit for the roadway improve- ment, a detailed acoustical study for the affected roadway segment shall be prepared to determine the need for any noise attenuation measures (such as setbacks, walls, and berms) for adjacent noise sensitive land uses (e.g., residential areas). 4.2.5.18 Prior to the approval of the design plans for the roadway improvements, a detailed landscaping plan shall be prepared to ensure that potential aesthetic impacts associated with any grading necessary for the improvement are mitigated. 4.2.5.19 As a condition of any off-site roadway improvement approval, monitoring of any grading for the presence of cultural and paleontological resources shall be required. If such resources are encountered during the Fading operations, the protocol described in section 4.9 of this EIR shall be required. 4.2.5.20 As a condition of any off-site roadway improvement approval, applicable construction-related water quality mitigation measures shall be required by the City Engineer. These hydrology and water quality mitigation measures are described in section 4.4 of this EIR 4.2.5.21 As a condition of any off-site roadway improvement approval, preparation of a traffic control plan for delays and hazards associated with construction impacts shall be prepared and approved by the City En~neer. For the widening of Otay Lakes Road between H Street and Telegaph Canyon Road, the following mitigation measure shall be required: 4.2.5.22 Plans prepared for the improvement of Otay Lakes Road between H Street and Tele~aph Canyon Road shall be designed to avoid impacts to -* the church library. 32 Significance After Mitigation: Less than significant C. BIOLOGICAL RESOURCES Standards of Significance: The proposed project would have a significant impact on biolo~cal resoumes if it: · Has an adverse or substantially adverse impact, either directly or indirectly through habitat modifications on any species identified as a candidate, sensitive, or special stares species in local or redonat plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service; · Has a substantial adverse impact to any wetland riparian resource protected under California Fish and Game Code Section 1600 or the Clean Water Act Section 404 or any other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service; · Conflict with the adjacency guidelines and policies of the City' s MSCP; · Has a substantial impact on the movement of any resident or miFatory fish or wildlife species or with established resident or mi~atory wildlife corridors, or impede the use of wildlife nursery sites; or · Conflicts with the provisions of adopted Habitat Conservation Plan, NatUral Conservation Community Plan, or other approved local, re~onal, or state habitat conservation plan or any other approved state, re~onal, or local conservation plan. Sensitive Plant Cotnmunities Impact: · Development of the EastLake 1311 project site would adversely affect sensitive plant cormmunities. [SEIZR, Subchapter 4.3. page 244] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: Development of the project site, including Fading and other construction activities, would impact 1.5 acres of disturbed Diegan coastal sage scrub, 6.55 acres of 33 non-native grassland, 0.1 acre of southern willow scrub, 0.2 acre of mule fat scrub, 0.14 acre of disturbed wetland, and 0.02 acre of freshwater marsh. Additional impacts could occur to 12.7 acres of disturbed habitat, 1.1 acre of ornamental vegetation, and approximately 1,140 linear feet (0.05 acre) of non-wetland jurisdictional waters of the U.S. for the off-site improvements to Otay Lakes Road, east of the Woods parcel. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4,3, pp. 248-249] As a condition of the future tentative map approval for the Woods and Vistas parcels and off-site Otay Lakes Road improvements, the following mitigation measures would be required: 4.3.5.1 Diegan coastal sage scrub, a Tier 121 plant community located outside the MSCP preserve lands and mitigated inside the MSCP preserve lands is at a ratio of 1:1. If mitigated outside the MSCP preserve lands, a 1.5:1 mitigation ratio is required. Thus, the project applicant shall provide mitigation of 1.5 to 2.25 acres of coastal gage scrub depending on the location of the mitigation site. These mitigation ratios for coastal sage scrub shall apply to the project whether or not the MSCP Implementing Agreement is in place at the time of issuance of grading permits. At the time a tentative map is processed, the applicant shall prepare and obtain approval of a conceptual mitigation plan for Diegan coastal sage scrub. Prior to the issuance of a grading permit or the cutting or removal of natural vegetation, whichever comes first, the project applicant shall obtain approval of a detailed mitigation plan and obtain all necessary permits. The applicant shall provide mitigation for impacts to coastal sage scrub by a combination of on-site preservation (1.2 acres is being preserved on- site), restoration of similar habitat on-site, or purchase of similar habitat from a mitigation bank. 4.3.5.2 Mitigation for impacts to non-native ~assland, a Tier III plant community, located outside the MSCP preserve lands and mitigated inside the MSCP preserve lands, is at a ratio of 0.5:1. If mitigated outside the MSCP preserve lands, a 1:1 mitigation ratio is required. The applicant shall mitigate between 3.28 acres to 6.55 acres, depending on the location of the mitigation site. These mitigation ratios for non-native grassland shall .-. apply to the project whether or not the MSCP Implementing Agreement is in place at the time of issuance of grading permits. 34 Preparation and approval of a detailed mitigation plan for non-native grassland shall be required at the time a tentative map is processed. Prior to the issuance of a grading permit or clearing and grubbing permit, whichever comes first, the project applicant shall obtain all necessary. permits. As an option, prior to the issuance of a grading permit, the applicant shall prepare and bond for the implementation of a non-native grassland restoration plan approved by the City of Chula Vista for impacts to non- native grassland. The restoration plan shall occur concurrent with project grading. 4.3.5.3 The City of Chula Vista requires that impacts to weftands be avoided to the maximum extent possible. When avoidance is not feasible, the applicant shall be required to minimize impacts to the greatest extent possible and mitigate for loss of wetland habitat, including weftand habitat creation of at least a 1:1 ratio. To mitigate impacts to weftands and non- weftand jurisdictional waters of the U.S., the following conditions would be required as a condition of the future tentative map approval for the Woods and Vistas parcels and off-site Otay Lakes Road improvements: a) As a condition of tentative map approval the applicant shall obtain a section 404 permit from USACE, a standard or conditional 401 Certificate from the Regional Water Quality Control Board, and a Streambed Alteration Agreement from CDFG (section 1603) for impacts to wetlands and non-weftand jurisdictional waters of the U.S. both on-site and off-site. b) Impacts to 0.1 acre of southern willow scrub shall require mitigation at a ratio of 3:1 for a total of 0.3 acre of southern willow scrub mitigation. If the southern willow scrub that is affected is occupied by least Bell's vireo, the mitigation could range from 3:1 to 5:1 as determined by USACE and CDFG federal section 404 and state 1603 permitting processes respectively. Impacts to 0.17 acre of mule fat scrub and 0.02 acre of freshwater marsh shall require mitigation at a ratio of 2:1 for a total of 0.38 acre of mitigation for these impacts. Also, a ratio of 1:1 is required for impacts to 0.14 acre of disturbed weftand. (Mitigation for the 0.14 acre of non-weftand jurisdictional waters will be subject to final determination by the USACE and CDFG.) Total mitigation for wetland impacts is 0.96 acre as shown in SEIR Table 4.3-8. Mitigation ratios are subject to approval by USACE and CDFG. As currently proposed, mitigation for impacts to wetlands would occur at the wetland restoration site located within Salt Creek 35 on the east side of Hunte Parkway immediately upstream of the detention basin. Prior to approval of the tentative map, the exact location and size of the wetland restoration area shall be determined and a weftand restoration plan shall be prepared and approved in conjunction with the 404 and 1603 permitting process. Significance After Mitigation: Less than significant Sensitive Plants Impact: · Development of the EastLake HI project site would adversely affect sensitive plants. [SEIR, Subchapter 4.3, page 244] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: Development of the EastLake HI project site. including Fading and other construction activities will adversely affect Otay tarplant. The grading of the proposed project will impact 24 individuals located on the eastern edge of the agricultural field on the Woods parcel. An additional 8 individuals will be indirectly impacted due to their proximity to development. This impact to 32 Otay tarplant is approximately three percent of the on*site population. Under the Habitat Loss and Incidental Take, an impact to 20 percent of the Otay tarplant is permitted provided that the impacts can be demonstrated as unavoidable pursuant to Sections 4.2.2.3 and 4.2.3.6 of the draft Chula Vista Subarea Plan. Draft equivalency findings are required for the take of narrow endemic plant species (i.e., Otay tarplant) pursuant to the provisions of the City's Subarea Plan. These findings have been submitted to the City and must be approved in order for take of narrow endemic plant species. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.3, page 2501 As a condition of the future tentative map approval for the Woods and Vistas parcels, the following mitigation measures for impacts to sensitive plants would be required. 4.3.5.4 As a condition of any tentative map approval, the applicant is required to mitigate impacts to a minimum of 32 Otay tarplant individuals at a 3:1 ratio. The actual number of tarplant individuals to be mitigated shall be 36 based on the results of a spring survey conducted prior to issuance of any Fading permit or the clearing, grubbing, cutting or removal of vegetation, whichever comes first., In no event shall mitigation be based on less than 32 individuals. The Habitat Loss and Incidental Take Permit would allow impacts to occur up to 20 percent of the on-site population. Findings of Equivalency, as defined in the draft Chula Vista Subarea Plan, have been prepared for consideration by the City Council. Findings of Equivalency require the City to demonstrat~ that compensation (mitigation) "would result in a Preserve design for the species of concern that is functionally equivalent to the Preserve design that would occur in the absence of the identified impact." ff the City has not acquired take authorization at the time of tentative map approval, federal and state take permits pursuant to the federal and state Endangered Species Acts must be obtained from USFWS and CDFG for impacts to listed species. If the MSCP Implementing A~eement is not in place at the time of tentative map approval, a 4:1 mitigation ratio for Otay tarplant shall be required. Preparation and approval of a detailed mitigation plan shall be required at the time a tentative map is processed. Prior to the issuance of a gading permit or clearing and grubbing permit, whichever comes first, the project applicant shall obtain all necessary permits. The applicant shall also implement a final restoration and long-term management progam on the existing agricultural land supporting Otay tarplant. The final restoration plan shall be developed and approved prior to gading permit approval. The final restoration plan shall describe soil salvage and seed collection procedures, habitat enhancement, maintenance and monitoring tasks, and success criteria for the existing population and recovered habitat. A conceptual restoration and management plan has been developed and is provided as an attachment to Appendix C4 in the SEIR. Significance After Mitigation: Less than significant Sensitive Wildlife Impact: · Construction activities could adversely affect sensitive wildlife. [SEIR, Subchapter 4.3, pp. 244-245] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen 37 or avoid the significant environmental effect as identified in the SEIR below a level of -- significance. Explanation: Construction activities, including eucalyptus and pepper tree removal and Fading could adversely affect raptors. Although no raptor nests were observed on the site, there is a potential for raptors to nest in the eucalyptus trees during the nesting season of February 1 to August 30. All active raptor nests are protected under the Fish and Game Code Section 3503.5.Construction noise could also adversely affect least Bell's vireo. If construction occurs during the breeding season of the least Betl's vireo (March 15 to September 15), there may be a loss of active nests for this species due to excessive noise. Excessive noise is considered 60 decibels at the nest site. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.3, pp. 250-251 ] To mitigate impacts to sensitive wildlife the following conditions would be required as a condition of the future tentative map approval for the Woods and Vistas parcels: 43.5.5 ff the City has not acquired take authorization at the time of tentative map approval for the Woods and Vistas, the applicant may be required to - proceed with a Section 7 consultation with USFWS pursuant to the permitting process under the Endangered Species Act for the removal of least Bell's vireo occupied southern willow scrub. A pre-construction presence/absence survey to locate nesting least Bell's vireo and to measure noise levels near the nest site shall be conducted by a qualified biologist. The pre-conslruction survey shall extend beyond the project footprint and shall be targeted for active nest of any sensitive bird species. The survey shall encompass suitable habitat surrounding the project footprint within 300 feet of the site during breeding season. In addition, if there are active nests, construction noise within 500 feet of an occupied least Bell's vireo nest shall not exceed 60 decibels during its breeding season of March 15 to September 15. Also, direct take of nests, eggs, or birds shall be avoided. A biological monitor shall be present if construction activities would occur during the least Bell~s vireo breeding season in order to minimize impacts to this species. 4.3.5°6 The applicant shall avoid removal of all on-site eucalyptus trees and the pepper trees in the off-site Otay Lakes Road improvement area during the raptor breeding season of February 1 to August 30 (i.e., grading should occur between September 1 and January 31). If this is not possible, the applicant shall conduct a preconstruction survey for nesting American kestrels, Cooper's hawks, red-shouldered hawks, and red-tailed hawks (or 38 other raptors) required to avoid impacts to these species. If an active raptor nest is located, the applicant shall flag the nest area and provide a 300-foot buffer zone. The applicant shall not allow construction activity within this 300-foot buffer area until the nest has been vacated. Significance After Mitigation: Less than significant MSCP Prese~,e Lands and City of San Diego Cornerstone Lands Impact: The City of San Diego "Cornerstone Lands" and the Chula Vista MSCP Preserve Lands may be adversely affected by the proposed project. [SEIR, Subchapter 4.3, page 245] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: No MSCP preserve lands are on-site; however, the City of San Diego's MSCP Multiple Habitat Planning Area is directly adjacent to the eastern boundary of each parcel. Upper and lower Otay Reservoirs are Cornerstone Lands within the City of San Diego's MSCP Multiple Habitat Planning Area. The Cornerstone Lands provide a natural open space corridor in the South Bay area and are incorporated into the City of San Diego MSCP Subarea Plan. The western boundary of the Panhandle parcel and the southwestern boundary of the Vistas parcel is adjacent to a 100 percent conservation area within the City of Chula Vista MSCP Preserve. The EastLake I11 project is within the Development Area as shown in Figure 2 of the adopted draft Chula Vista Subarea Plan. Management issues for projects adjacent to the City of San Diego's Multiple Habitat Planning Area or the City of Chula Vista's MSCP preserve lands are outlined in the respective Subarea plans. Adjacency management issues discussed in the City of San Diego's Subarea plan include drainage, toxics, lighting, noise, barriers, invasive species, and brush management. The City of Chula Vista Subarea Plan addresses barriers, drainage, toxics, lighting, noise, invasives, and buffers. Compliance with the adjacency guidelines ensures that projects will not damage the integrity of the preserve system. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.3, pp. 251-252] 39 To mitigate potential impacts to adjacent City of Chula Vista Preserve Lands and City of San Diego MSCP Cornerstone LandS, the following conditions would be required as a condition of the future tentative map approval for the Woods and Vistas parcels: 43.5.7 In order to reduce indirect impacts on Chula Vista MSCP Preserve Lands and City of San Diego Cornerstone Lands below a level of significance, the following mitigation measures shall be a condition of any future tentative map approval and shall be implemented prior to the issuance of any Fading permit in accordance with land use adjacency guidelines defined in the draft Chula Vista Subarea Plan. · The proposed project shall comply with the City of Chula Vista MSCP Subarea Adjacency Management Issues (Section 6.3.2) regarding drainage into the preserve. The Subarea Plan adjacency requirements prohibit the release of materials that could deFade the ecosystems in the preserve and mandate the maintenance of drainage facilities. The Hydrology section (Chapter 4.4) also discusses impacts and mitigation requirements that ensure that downstream impacts within Salt Creek would be avoided. · lllegal intrusions into the preserve (e.g., orchards, decks~ etc.) shall be prevented and removed on an annual basis and on a complaint basis. · In order to prevent illegal intrusions by domestic animals, humans, and motorized and non-motorized vehicles into the preserve, fencing or other methods aFeed upon by the Cities of Chula Vista and San Diego shall be required. · In order to avoid indirect drainage impacts to the preserve, the EastLake m project will comply with the MSCP Subarea Adjacency Management Issues regarding drainage (Section 6.3.2 of the MSCP Subarea Plan). · In order to protect wetland habitats in the Salt Creek watershed and also allow for the establishment of landscaped areas adjacent to the creek, limited use of fertilizers, herbicicles, and pesticicles in the landscaped areas within and adjacent to Salt Creek shall only be allowed during the landscape establishment period. Use of these chemicals shall be prohibited after the establishment period unless unusual circumstances warrant their use. In order to ensure that the wetland buffer is maintained with minimal use of chemicals and in a way that fosters establishment of a native plant community, the maintenance and monitoring of the wetland buffer portion of the slope 40 shall be carried out by a qualified native landscape maintenance firm and monitored by a qualified biolo~st. In addition. prior to the approval of the tentative map, the landscape plans for the manufactured slopes adjacent to Salt Creek shall be reviewed and approved by the City to ensure that native plants are used on the that portion of the slope between the wetland buffer area and the ~eenbelt trail. · All lighting on the site shall be directed away from the preserve or shall be adequately shielded during construction activities. Residences outline the periphery of the preserve on the Woods parcel; therefore, lighting will not be a significant issue. Commercial development is proposed for the Vistas parcel and lighting adjacent to these areas shall be directed away from the preserve or shielded with native or non- invasive plants, berms, or walls. · Noise impacts adjacent to the preserve lands shall be minimized. Berms or walls shall be installed adjacent to commercial areas and any other use that may introduce noises that could impact or interfere with wildlife utilization of the preserve. Construction activities will include noise reduction measures or be conducted outside the breeding season of sensitive bird species. In particular, grading resuictions shall be implemented during the breeding season of the California gnatcatcher, and if construction is proposed during the breeding season, noise levels shall not exceed 60 dB(A) L~q within 500 feet of an active gnatcatcher nest. Significance After Mitigation: Less than significant Panhandle Site Impact: · Development of the Panhandle site may adversely affect biolo~cal resources [SEIR, Subchapter 4.3, page 246] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of sigTdficance. Explanation: Development of the Panhandle site may cause significant impacts to existing biolo~cal resources on- and off-site (City' s Preserve Lands and the City of San 41 Diego Cornerstone Lands), including disturbed coastal sage scrub, non-wet. land jurisdictional waters, and potential wetlands (i.e., vernal pools). Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.3, page 252] 4.3.5.8 Prior to the approval of any detailed development plans at the Panhandle site, an updated biological survey and wetland delineation shall be conducted and a detailed impact analysis prepared. Detailed mitigation measures for impacts at the Panhandle site would be required at that time and would consist of (1) application of mitigation ratios described above for the Woods and Vistas parcels for impacts to coastal sage scrub, and (2) compliance with the MSCP and adhei'ence to the adjacency guidelines prescribed in the Chula Vista Subarea Plan and the City of San Diego MSCP to reduce impacts to the City~s Preserve Lands and the City of San Diego Cornerstone Lands to below a level of significance. This will include conformance with adjacency guidelines such as drainage, landscaping, noise, and domestic pets. In. addition, if impacts to non- wetland jurisdictional waters and potential wetlands (i.e., vernal pools) are identified on the Panhandle site based on a detailed wetland delineation, a section 404 permit from USACE, a standard or conditional 401 Certificate from the Regional Water Quality Control Board, and a Streambed Alteration Agreement from CDFG (section 1603) would be required. 4.3.5.9 If the City does not have take authorization prior to approval of tentative maps, federal and state take permits pursuant to the federal and state Endangered Species Acts must be obtained from USFWS and CDFG for impacts to listed species. Significance After Mitigation: Less than significant D. HYDROLOGY/DRAINAGE Standards of Significance: The proposed project would have a significant impact on hydrology, drainage, and water quality if it: · Violates water standards or water discharge requirements as set by the San Diego Regional Water Quality Control Board; · Substantially depletes groundwater supplies or interferes substantially with groundwater recharge; · Substantially alters the existing drainage pattern of the site or the area which would result in substantial erosion or siltation on- or off-site; · Create or contribute runoff water which would exceed the capacity of existing or planned storm water systems or provide additional sources of polluted runoff; · Alteration of an existing 100-year floodplain or flood re,me; · Subject existing or proposed people or structures to flooding due to alteration of an existing 100-year floodplain; · Potentially degrade the water quality associated with a sensitive wetland or hydrolo~c resource; or · Substantially degrade water quality. Impact: · Development of the proposed project could result in significant water quality and hydrolo~c impacts. [SEIR, Subchapter 4.4, pp. 259, 263-264, 266-268] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into. the project that will substantially lessen or avoid the si~_~mificant environmental effect as identified in the SEIR below a level of significance. Explanation: Under the developed site conditions, potentially significant water quality impacts could result from runoff flowing across impervious surfaces as well as landscaped areas containing pollutants. Additional impacts to water quality may result from the use of reclaimed water for on-site irrigation of parks and nonresidential landscape. The only project runoff reaching the Otay Reservoirs would be from the manufactured slopes along the eastern boundary of the Vistas. Development of the proposed project could cause an increase in the amount of runoff and have potentially si~nificant hydrolo~c impacts on downstream drainage facilities during the 100-year, 50-year, and t0-year storm events. In addition, the proposed diversion from the Vistas neighborhood may exceed the capacity of the existing Olympic Parkway storm drain system, which would be a significant impact if storm water runoff is not directed beyond the Olympic Parkway system to the existing Salt Creek outfall(s) located on-site. 43 Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.4, pp. 270-274] 4.4.5.1 Prior to approval of the tentative map and/or final grading and design plans, as determined by the City Engineer. the applicant shall obtain approval of a drainage plan for the project that will convey storm water runoff generated by the project to a public drainage system adequate to carry those waters in accordance with current engineering standards as set forth in the Public Works Standards for the City of Chula Vista. 4.4.5.2 As a condition of fading permit and tentative map approval, no grading or other surface-disturbing activities on any site shall be allowed between October 1 and the following April 1, or when the City Engineer determines that erosion, mudflow, or sediment discharge from grading may adversely affect downstream properties, drainage courses, storm drains, streets, easements, or public or private facilities or improvements unless an erosion and sedimentation control system approved by the City En~neer has been implemented on the site to the satisfaction of the City Engineer. Erosion control measures may include, but are not limited to, the short-term use of ~avel bags, matting, mulch, berms, hay bales, silt fences, or similar devices along all Faded areas to minimize erosion and sediment transport. The exact design, location, and schedule of use for such devices shall be conducted pursuant to direction and approval by the City En~neer. 4.4.5.3 Prior to issuance of Fading permits or any landform modification, the applicant shall delineate areas of native vegetation to remain undisturbed based on adopted grading plans to avoid any off-site impacts. 4.4.5.4 Prior to the issuance of a Fading permit, the applicant shall locate temporary desilting basins at all discharge points adjacent to drainage courses or where substantial drainage alteration is proposed in the Fading plan. The exact design and location of such facilities shall be based on hydrological modeling and determined pursuant to direction by the City Engineer. 4.4~5.5 The applicant shall, within six months of commencement of grading activities, hydroseed and landscape Faded and common areas with appropriate found cover vegetation consistent with the City's grading ordinance and with the mitigation requirements in the Biology section of the EIR. These revegetated areas shall be inspected monthly by a 44 qualified biologist until vegetation has been firmly established as determined by the City. 4.4.5.6 Compacted areas shall be scarified by the applicant, where appropriate, to induce surface water infiltration and revegetation as directed by the project geologist, City Engineer, and/or biolojst. 4.4.5.7 Prior to project implementation, the applicant shall obtain either (a) General Construction Activity Storm Water Permits (NPDES Permit No. CA 0108758) from the SWRCB or (b) a municipal permit from the City of Chula Vista that is in effect at the time of issuance of construction/grading permits. Such permits are required for specific (or a series of related) construction activities that exceed five acres in size and include provisions to eliminate or reduce off-site discharges through implementation of a SWPPP. Specific SWPPP provisions include requirements for erosion and sediment control, as well as monitoring requirements both during and after construction. Pollution control measures also require the use of best available technology, best conventional pollutant control technology, and/or best management practices to prevent or reduce pollutant discharge (pursuant to SWRCB definitions and direction). The SWPPP also includes specified vehicle fueling and maintenance procedures and hazardous materials storage areas to preclude the discharge of hazardous materials used during construction (e.g., fuels, lubricants, and solvents) and specific measures to preclude spills or contain hazardous materials, including proper handling and disposal techniques and use of temporary impervious liners to prevent soil and water contamination. 4.4.5.8 Post-construction erosion control measures shall be included in the project's tentative map and/or final design as determined by the City Engineer, and implemented by the applicant where proposed disturbance is adjacent to or encroaches within existing drainage courses as determined by the City Engineer. 4.4.5.9 The applicant shall incorporate all applicable BMPs contained in the State Best Management Practices to be considered in the Development of Urban Storm Water Management Plan in the project's tentative map and/or final design plans as determined by the City Engineer. Specifically, these may include measures such as the use of detention/desilting basins, retention structures, sediment/oil traps at inlets or manholes, infiltration facilities, permeable pavements, 45 vegetation controls, discharge controls. maintenance (e.g., street sweeping). and erosion controls. 4.4.5.10 As a condition of approval of the tentative map, the applicant will be required, prior to issuance of a ~ading permit for any area of the project (including off-site areas) draining towards the Upper or Lower Otay Reservoirs. to accomplish the following: a) Obtain the approval of the City of Chula Vista and all other applicable agencies for any proposed structural drainage runoff detention and/or diversion facilities within the Otay Lakes watershed. b) Obtain the approval of the Ciiy of Chula Vista and all other applicable agencies of all operational and maintenance agreements associated with any proposed structural drainage runoff detention and/or diversion facilities within the Otay Lakes watershed. 4.4.5.11 The applicant shall design surface drainage to collect and discharge runoff into natural stream channels or drainage structures. All drainage systems shall be designed in accordance with the City's Public Works Standards. 4.4.5.12 Project operation and maintenance practices shall include a schedule for regular maintenance of all private drainage facilities within common development areas to ensure proper working condition. This will be the responsibility of the homeowners association. 4.4.5.13 The applicant shall design surface and subsurface drainage to preclude ponding outside of designated areas, as well as flow down slopes or over disturbed areas. 4.4.5.14 Runoff diversion facilities (e.g., inlet pipes and brow ditches) shall be used where appropriate to preclude ranoff flow down graded slopes. Drainage terraces for slopes in excess of 40 feet in vertical height shall only be required for stabilization purposes. Slopes in excess of 40 feet in height may not require terraces provided that slope-specific analysis demonstrates that such measures are not needed in order to achieve the intent of the City's grading ordinance. The applicant shall demonstrate compliance in grading plan prior to issuance of gading permit. 4.4.5.15 Energy-dissipating structures (e.g., detention ponds, riprap, or drop structures) shall be used at storm drain outlets, drainage crossings, 46 and/or downstream of all culverts, pipe outlets, and brow ditches to reduce velocity and prevent erosion. The applicant shall demonstrate compliance in gading plan prior to issuance of grading permit. 4.4.5.16 Prior to issuance of the grading permit for any site in that drainage area, the applicant shall demonstrate that the proposed detention facilities would reduce 5-, 10-, 25-, 50-, and 100-year post-development peak flows to equal to or less than pre-development conditions. The proposed on-site detention facilities shall be desig-aed to ensure that there is no increase in downstream (i.e., south of Olympic Parkway) velocities in Salt Creek. See also mitigation measure 4.3.5.7 in Chapter 4.3, Biological Resources. 4.4.5.17 Long-term maintenance of all on- and off-site detention/desilting basins shall be the responsibility of a maintenance district, homeowners association, or other mechanism approved by the City. Prior to issuance of the first grading permit for the Salt Creek detention basins or approval of the first final map, a maintenance program for the ordinary and usual maintenance of the Woods' detention basin shall be established. The maintenance program shall include, but not be limited to (a) a manual describing the operation and maintenance of the detention basins; (b) an estimate of the cost of such operation and maintenance activities; and (c) a funding mechanism for financing the maintenance program. The applicant shall be responsible for obtaining the approval of the maintenance program for all applicable federal and state governmental agencies. 4.4.5.18 Regular maintenance of the greenbelt and community trails shall be the responsibility of the City of Chula Vista or the homeowners association, depending on designation, to minimize the potential for erosion into Lower Otay Reservoir. Prior to issuance of the first grading permit for the trails or approval of the first final map, a maintenance program for the ordinary and usual maintenance of the trails shall be established. 4.4.5.19 Urban runoff control steps that would reduce direct impacts from project pollutants to a level below significance are stated below. These measures shall be made a condition of the tentative map and shall be implemented on the final grading and improvement plans. Imple- mentation of these measures is the responsibility of the applicant. a) Per the Clean Water Act, "best management practices" to control pollutants and sediment from entering storm water runoff are required for the project area. Source control BMPs via landscaping 47 of all slopes and street fights-of-way shall be provided to prevent erosion. Any other applicable source control or BMPs which may be implemented on a citywide basis in conjunction with the City's Municipal NPDES permit shall be incorporated into the specific plan. The size, capacity, and location of any other pollution control devices which would be used to capture urban pollutants on-site will be detennined as part of the project-specific drainage studies prior to the approval of future subdivision maps. b) The City's Department of Hanning and Building shall verify that the mitigation measures are conditions for the approval of the tentative map and that they are implemented on the ~ading plans and improvement plans for the project. 4.4.5.20 In order to avoid indirect impacts on the Otay Tarplant Preserve, Preserve lands, and Otay Lakes, fertilizers, herbicides, and pesticides shall not be applied to the manufactured slopes along the eastern periphery of the Woods and Vistas parcels. Potable water shall be used for irrigation. 4.4.5.21 An educational progain to discourage access and contact with the reservoirs shall be required as a condition of approval for future temative maps. Significance After Mitigation: Less than sig-ni~cant Impact: Groundwater seepage could create a significant impact. [SEIR, Subchapter 4.4, page 266] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant envirom-nental effect as identified in the SEIR below a level of significance. Explanation: Groundwater seepage, which is compounded by changes in rainfall and drainage panems, may destabilize soil and adversely affect construction. Future irrigation would introduce significant quantities of water into the underlying soil, which would also create the potential for seepage at the face of slopes or at the surfaces of lower elevation pads. If seepage were subsequently observed throughout the site, this could indicate the presence of perched goundwater flowing laterally rather than a regional ~oundwater 48 table. Changes in rainfall and/or site drainage may similarly produce other areas of locally perched Foundwater prone to seepage. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.4, page 274] 4.4.5.22 For areas with the greatest potential for groundwater seepage, impacts could be reduced to a less than significant level through installation of subsurface drains as determined by the Soils En~neer and approved by the City En~neer. Implementation of these measures is the responsibility of the applicant. 4.4.5.23 The applicant shall obtain a Dewatering Waste Discharge Permit (NPDES No. CA0108804) for the removal and disposal of groundwater (if necessary) encountered during construction. Such permits are intended to ensure compliance with applicable water quality, and beneficial use objectives, and typically entail the use of BMPs to meet these requirements. Discharge under this permit will require compliance with a number of physical, chemical, and thermal parameters (as applicable), along with pertinent site-specific conditions (pursuant to Redonat Water Quality Control Board direction). Significance After Mitigation: Less than significant Panhandle Site Impact: · Development of the Panhandle site could result in sig-nificant water quality and hydrolo~c impacts. [SEIR, Subchapter 4.4, page 266, 268] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of si~nificance. Exl~lanation: In general, runoff impacts resulting from future development of the Panhandle site would be similar to those identified elsewhere within the project site. Future development could cause an increase in the amount of ranoff and have potentially significant impacts on downstream drainage facilities. Site-specific review would be required when specific plans become available. 49 Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SE][R, Subchapter 4.4, page 274] 4.4.5.24 As a condition of approval for any future development plans at the Panhandle site, the project applicant shall comply with applicable federal, state, and City regulations, including the Clean Water Act and more specific objectives mandated by the San Diego Regional Water Quality Control Board Order No. 2001-01. As required above for the Woods and Vistas, any future development proposal shall reduce storm ranoff peak rates and velocity to predevelopment levels and prohibit any increase in pollutant levels in ranoff. To achieve these standards, future development of the site shall employ BMPs to reduce runoff and water quality impacts to the maximum ext~nt practicable. Conformance is supported through preparation of a SWPPP, which is required for approval of NPDES and other permits. Significance After Mitigation: Less than significant Impact: · Groundwater seepage could create a significant impact on the Panhandle site. [SEIR, Subchapter 4.4, page 267] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in. or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: Groundwater seepage, which is compounded by changes in rainfall and drainage patterns. may destabilize soil and adversely affect construction. Future irrigation would introduce significant quantities of water into the underlying soil, which would also create the potential for seepage at the face of slopes or at the surfaces of lower elevation pads. If seepage were subsequently observed throughout the site, this could indicate the presence of perched ~oundwater flowing laterally rather than a redonat ~oundwater table. Changes in rainfall and/or site drainage may similarly produce other areas of locally perched ~oundwater prone to seepage. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.4, page 274] 5O 4.4.5.25 For areas on the Panhandle site with the greatest potential for groundwater seepage, impacts could be reduced to a less than significant level through installation of subsurface drains as determined by the Soils En~neer and approved by the City En~neer. Implementation of these measures is the responsibility of the applicant. Significance After Mitigation: Less than significant E. LANDFORM ALTERATION/VISUAL QUALITY Standards of Significance: The proposed project would have a significant impact on landform and visual quality if it: · Has a substantial adverse effect on a scenic vista, or obstructs or substantially alters the visual character of a designated public view; Substantially damages scenic resources, including but not limited to trees, rock outeroppings~ and historic buildings within a state scenic highway; · Conflicts with the goals and policies established for preserving scenic highways and roads; · Results in architecture, urban design, landscaping, and/or landforms that negatively detract from the prevailing aesthetic character of the site or surrounding area; or · Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. Impact: · Development of the project could result in sig~nificant impacts to landforms and visual quality. [SEIR, Subchapter 4.5, pp. 287, 290, 299] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: The proposed development would alter existing landforms and the visual characteristics of the site through ~ading, excavation of the ridge tops, and in-filling of canyons. Open expanses of rolling hills used for agricultural purposes would be developed with residential, public/quasi-public, and commercial areas separated by open 51 space. Development would, therefore, affect views from surrounding areas and result in · significant impacts to visual quality. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.5, pp. 302-303] 4.5.5.1 As a condition of approval for the anticipated future tentative map for the Woods and Vistas, the applicant shall comply with the respective SPA Plan Grading Concepts and Design Guidelines to ensure that project's direct significant landform alteration and visual impacts are reduced to below a level of sig'nificance. These measures have been included in the conceptual grading plan included in this EIR and are listed below as mitigation to ensure that the future tentative map would be in compliance with the SPA Plan. The SPA Plan mitigation requirements included in the Design Guidelines involve methods for architectural and site design, housing density and arrangement, housing types, facade textures, lighting, fencing, circulation, and comprehensive grading and landscaping plans, among other measures and techniques. Specifically, the SPA Plan and Design Guidelines provide the following that serve to reduce the aesthetic impacts: a) A Community Landscape Design that addresses streetscapes, provides landscape intensity zones (see SEIR Fignres 4.5-7 and 4.5-8), geenbelt edge treatments at Salt Creek, and slope treatment for erosion control. b) Grading concepts that ensure manufactured slopes that are contoured and blend and mimic with adjacent natural slopes. c) Landscaping concepts that provide for a transition from the manicured appearance of developed areas to the natural landscape in open space areas. d} Landscaping concepts that include planrings selected to frame and maintain views. Landscaping should not block views created through gading and/or site design. Panhandle Site Impact: · Development of the Panhandle site may result in significant impacts to landforms and visual quality. [SEIR, Subchapter 4.5, pp. 300, 302] Finding: Pursuant to section 15091(a)(1l of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the sig'nificant environmental effect as identified in the SEIR below a level of sig-rdficance. Explanation: Development of the Panhandle site could alter existing landforms and the visual characteristics of the site through grading and other construction activities. Open expanses used for agricultural purposes would be developed with public/quasi-public or residential areas. Development would, therefore, affect views from surrounding areas and could result in significant impacts to visual quality. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.4, page 303] 4.5.5.2 When development plans are proposed for the Panhandle, a landform alteration and visual quality impact assessment shall be conducted and mitigation measures shall be required to reduce potentially significant impacts. These measures would be similar to those described above for the Woods and Vistas including incorporation of appropriate landscape, Fading, and architectural guidelines. F. GEOLOGY/GEOLOGIC HAZARDS Standards of Significance: The project would have a significant impact if it: · Is located on 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; · Is located within an Alquist-Priolo Special Studies Zone or is traversed by an active fault; · Results in substantial soil erosion or the loss of topsoil; or 53 · Results in seismic-related Found failure. including liquefaction. Impact: · Project implementation may result in significant impacts to geologic resources and/or occur as a result of geologic hazards. [SEIR, Subchapter 4.6, pp. 311-312] Finding: Pursuant to section 15091(a)(1 ) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into. the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: Significant impacts could result from development on compressible and expansive soils. The highly expansive nature of Diablo clays, which predominate on the project site, makes them unsuitable for foundation supports. Alluvial and colluvial deposits in the drainage courses could undergo liquefaction. Unstable conditions may result from Fading in areas with cut or underlying fill slopes. Slope faces associated with clay beds may also become unstable due to an increased potential for seepage caused by miFation of perched Foundwater. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.6, page 314] 4.6.5.1 As a condition of issuance of Fading permits, the project applicant shall be required to provide a detailed geotechnical/soils report to the City Engineer to ensure that the following mitigation requirements axe implemented in the Fading plan: a) Upper soil layers shall be removed to a depth of two to three feet during initial construction periods and replaced with competent compacted fill. (Erosion and runoff measures are addressed in Hydrology/Drainage, Subchapter 4.4. of the SEIR.) b} Removal of the colluvium and alluvium deposits, followed by replacement with compacted fill shall be required to eliminate the potential for liquefaction. c) The potential for settlement of compressible soils shall be minimized by removing these soils and replacing them with compacted fill in areas that would be subjected to new fill or structural loads. 54 d) Highly expansive soils shall be kept below five feet of finished grade to reduce the potential for differential movement. Significance After Mitigation: Less than significant Panhandle Site Impact: Project implementation may result in significant impacts to geolo~c resources and/or occur as a result of geolo~c hazards. [SEIR, Subchapter 4.6, pp. 312-313] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: Significant impacts could result from development on compressible and expansive soils. The highly expansive nature of Diablo clays makes them unsuitable for foundation supports and alluvial and colluvial deposits could undergo liquefaction. Unstable conditions may result from grading in areas with cut or unde~ying fill slopes. Slope faces associated with clay beds may also become unstable due to an increased potential for seepage caused by migation of perched groundwater. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.6, page 314] 4.6.5.2 As a condition of approval of issuing any Fading permit on the Panhandle site, detailed mitigation measures for impacts at the Panhandle site shall be required at the time development plans are proposed. As with the Woods and Vistas, a detailed geotechnica//soils report shall also be required to identify development hazards and constraints and to determine appropriate mitigation. Significance After Mitigation: Less than significant G. NOISE The proposed project would result in a sig-nificant impact ori~nating from noise if it would: 55 · Result in exterior noise levels that exceed 65 CNEL in residential areas, schools, libraries and parks, and 70 CNEL in office, business, and professional uses. and for churches and auditoriums; · Result in interior noise levels that exceed 45 CNEL for single- and multi-family residential homes and 50 CNEL for the interior of commercial and professional offices; or · Result in noise levels from construction activities to residential receptors that exceed 75 dB, averaged over a 12-hour period, or to any least Bell' s vireo nest site during the breeding season that exceed 60 dB. D'aff~c on Major Roadways Impact: · Noise associated with traffic on major roadways may adversely affect the proposed project. [SEIR, Subchapter 4.7, pp. 324-325] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the sig'nificant environmental effect as identified in the SEIR below a level of si~dficance. Explanation: The proposed project would be affected by traffic noise generated on Otay Lakes Road, a portion of Hunte Parkway, and Ol.vmpic Parkway. The traffic on these streets could generate noise levels geater than 65 CNEL, which is the City' s residential exterior standard, at gound-level sensitive receivers on a limited portion of the project site. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.7, pp. 330, 336-337] 4.7.5.1 The applicant shall achieve mitigation of potential first-floor exterior noise impacts through the construction of sound barriers as illustrated in SEIR Figures 4.7-5 through 4.7-7. On the Woods site, a barrier varying from four to six feet in height is required on the edge of the pad slopes for the single-family homes along Otay Lakes Road and a portion of Hunte Parkway. On the Vistas site, the single-family homes along Otay Lakes Road and the single- and multi-family homes along Olympic Parkway _. require barriers that are four to six feet in height. 56 The barriers shall be either walls or berms---~r a combination thereof~ constructed of solid material with a density of at least four pounds per square foot and should not have any cracks or gaps. Examples of acceptable barrier materials include, but are not limited to, masonry block, wood frame with stucco, 0.5-inch-thick Plexiglas, or 0.25-inch-thick plate glass. If transparent barrier materials are used, no gaps shall occur between the panels. The transmission loss through a barrier shall be at least 10 decibels greater than the estimated barrier attenuation (Federal Highway Administration 1979:34). If a barrier attenuates noise levels by 5 dB(A) at a receiver location, the barrier transmission loss must be at least 15 dB(A) to prevent audible noise from traveling through the barrier and adding to the acoustical environment. Bamer heights are relative to final pad elevations. 4.7.5.2 As seen in SEIR Figures 4.7-5 through 4.7-4 and Tables 4.7-4 and 4.7-5, even with the construction of noise barriers. exterior noise levels at the second floor for the single- and multi-family residences along Otay Lakes Road, a portion of Hunte Parkway, and Olympic Parkway could exceed 65 CNEL. Therefore, standard construction is not assumed to adequately reduce interior noise levels to below 45 CNEL at these locations. At the time that building plans are available for these units, and prior to the issuance of building permits, the applicant shall be required to submit a detailed acoustical analysis prepared by a qualified acoustical consultant that demonstrates that the building structure is adequately designed such that second-floor interior noise levels due to exterior sources will be at or below the 45 CNEL interior standard. Where exterior noise levels exceed 60 CNEL, additional measures shall be required to attenuate noise to the 45 CNEL standard, such as inoperable windows or double-paned windows. For those units that require the windows to be closed to achieve the City's interior noise standard, forced- air circulation or air conditioning shall be provided by the applicant. 4.7.5.3 Future noise levels at the elementary school are projected to exceed 65 CNEL. Mitigation of the potential exterior noise impacts on the outdoor usable areas such as the play areas can be achieved through the construction of barriers varying from eight to five feet in height. Mitigation of the exterior use areas could also be achieved through the site design by placing the exterior use areas on the sides of the buildings opposite the roadway. 4.7.5.4 A site design for the proposed fire station is not available at this time. Future traffic on Otay Lakes Road is projected to generate noise levels on 57 the fire station site in excess of 65 CNEL. If exterior use areas such as eating areas or recreation areas (e.g., basketball courtsl are proposed for the fire station, they shall be placed on the side of the buildings opposite the roadway. This will ensure that these use areas are adequately shielded from roadway noise. 4.7.5.5Additionally, as indicated. it is assumed that the City's 45 CNEL residential interior standard is applicable to the living and sleeping quarters in the fire station. Given that future exterior noise levels due to traffic are projected to exceed 65 CNEL, standard construction cannot be assumed to adequately reduce projected interior noise levels to below 45 CNEL. Although it is likely that design of the fire station will be sufficient to reduce exterior noise levels from traffic on Otay Lakes Road to acceptable interior standards, the potential for interior noise standards to be exceeded does exist. Consequently, at the time that building plans are available for the fire station. and prior to the issuance of building permits, a detailed acoustical study shall be prepared by a qualified acoustical consultant that demonstrates that the building structure is adequately designed such that noise levels in the living and sleeping quarters will be at or below the City' s 45 CNEL interior noise standard. 4.7.5.6 If substantial changes in the proposed project ~ading occur as the final design develops through the tentative map process, additional noise analyses will be required. Significance After Mitigation: Less than significant Construction Noise Impact: · Construction noise may result in a sig~nificant impact. [SEIR, Subchapter 4.7, page 328] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~-:n~ficant envirommental effect as identified in the SEIR below a level of si~i~cance. Explanation: If least BelFs vireo are present in the hal~itat north of Otay Lakes Road during project construction, excessive construction noise (60 decibels or more) at any least Bell's vireo nest site during the breeding season would be considered a significant impact. 58 Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.7, page 337] 4.7.5.7 If construction is to occur during the breeding season for the least Bell's vireo (March 15-September 15), a qualified biolo~st shall conduct a focused survey of the least Bell's vireo habitat for breeding activity. If the least Bell's vireo is observed, further mitigation measures will be required. These include providing a temporary noise barrier, monitoring construction noise at the edge of the occupied habitat, and noise attenuation for noise levels exceeding 60 dB(A). Monthly noise monitoring reports would be submitted to the City of Chula Vista. Implementation of this mitigation measure is the responsibility of the applicant. Significance After Mitigation: Less than significant D'affic on bzte~77al Roadways Impact: Noise associated with traffic on internal project roadways could result in a significant impact. [SEIR, Subchapter 4.7, page 328] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~onificant environmental effect as identified in the SEIR below a level of si~ordficance. Explanation: Interior noise levels at the residential pads adjacent to Street "P" within the Vistas site could exceed the City' s 45 CNEL residential interior noise standard resulting in a significant noise impact from traffic on Street "P". Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.7, page 337] 4.7.5°8 Where exterior noise levels exceed 60 CNEL, additional measures shall be required to attenuate noise to the 45 CNEL standard, such as inoperable windows or double paned windows. For those units that require the windows to be closed to achieve the interior noise standard, forced-air circulation or air conditioning shall be provided by the applicant. 59 Significance After Mitigation: Less than significant Noise Getwrated By Non-Residential Uses Impact: · Noise generated by nonresidential uses on the project site may result in a significant impact. [SEll>,, Subchapter 4.7, page 328] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: Any proposed commercial uses would be required to comply with the noise level standards specified in the City's Noise Ordinance. Because the specific uses are not 'known, development of the Commercial areas could result in si~dficant noise impacts if those uses were to violate the Noise Ordinance. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.7, page 337] 4.7.5.9 At the time that specific uses are proposed for the commercial areas, the development plans shall be reviewed and, if deemed necessary. by the City Planning Director, acoustical studies shall be prepared that demonstrate compliance with the City' s noise standards. Significance After Mitigation: Less than significant Panhandle Site Impact: · Significant noise impacts could result with development of the Panhandle site [SEIR. Subchapter 4.7, page 329] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of sig~nificance. 6O Explanation: Significant noise impacts from construction. project operations, and/or traffic-related noise could result if the Panhandle site is developed for public/quasi-public use or low densit3, residential uses. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.7, page 337] 4.7.5.10 At the time development plans for the Panhandle are proposed, a noise study shall be conducted to identify potential impacts and appropriate mitigafon, if required. Mitigation may consist of noise barriers and/or architectural treatments, depending on the characteristics and source of the impact. Significance After Mitigation: Less than significant H. AIR QUALITY Standards of Significance: California Air Resources Board For long-term emissions, the cumulative impacts of a project can be measured by the deuce to which the project is consistent with redonat plans to improve and maintain air quality. The redonat plan for San Diego is the 1991/1992 RAQS and attached Transportation Control Measures Plan as revised by the triennial updates adopted on December 12, 1995 and June 1998. The California Air Resources Board provides criteria for determining a project's impacts (State of California 1989), which include the following: 1. Is a redonat air quality impact plan being implemented in the project area? 2. Is the project consistent with the ~owth assumptions in the re~onai air quality plan? 3. Does the project incorporate all feasible and available air quality control measures? City of Chula Vista The proposed project would result in a significant impact to air quality if it: · Conflicts with or obstructs implementation of an applicable air quality plan; · Violates any ambient air quality standard; 61 · Contributes substantially to an existing or projected air quality violation; or -' · Exposes sensitive receptors to substantial pollutant concentrations. The City of Chula Vista uses the following South Coast Air Quality Management District thresholds to assess the significance of air quality impacts (SCAQMD 1993 ): Pollutant Proiect Construction Project Operation Carbon Monoxide 24.75 tons/quarter 550 pounds/day Reactive Organic Compounds 2.5 tons/quarter 55 pounds/day Oxides of Nitrogen 2.5 tons/quarter 55 pounds/day Oxides of Sulfur 6.75 tons/quarter 150 pounds/day PM~0 6.75 tons/quarter 150 pounds/day Co~iformance with Regional Air QualiD' Plans Impact: · The proposed project is not consistent with the ~owth projections of the local regional air quality plan [SEIR, Subchapter 4.8, pp. 349-350] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: The proposed project is not consistent with the g-rowth projections of the local redonat air quality plan and, consequently, is not consistent with the goals and objectives of that plan. This represents a significant impact. Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of significance. The infeasibility of the No Project alternative is described in Section XI of these findings. However, measures have been incorporated into the proposed project design to reduce air quality impacts. These measures include pedestrian trials (Chula Vista Greenbelt Trail and EastLake Community Trail ), on-street bicycle paths, and public transit stops planned for Hunte Parkway, Olympic Parkway, and/or Otay Lakes Road. Future plans exist for extension of trolley service to the Eastern Territories as well. [SEIR, Subchapter 4.8, page 360] Significance After Mitigation: These measures axe insufficient to attain confonnance with the regional air quality plan. This impact is therefore significant and unmitigated with implementation of the proposed project. Project Operation Impacts Impact: · Project operations-related emissions would cause a significant regional impact on air quality. [SEIR, Subchapter 4.8, pp. 350, 355] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: Project operations-related emissions, including those from stationary and mobile sources, are projected to exceed SCAQMD thresholds and, therefore, would result in a potentially significant regional impact on air quality. Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of significance. The infeasibility of the No Project alternative is described in Section XI of these findings. However, measures have been incorporated into the project design to reduce operational air quality impacts. These measures include pedestrian trails (Chula Vista Greenbelt Trail and EastLake Community Trail), on-street bicycle paths, and public transit stops planned for Hunte Parkway, Olympic Parkway, and/or Otay Lakes Road. Future plans exist for extension of trolley service to the Eastern Territories as well. [SEIR, Subchapter 4.8, pp. 360-361] Significance After Mitigation: These measures are insufficient to reduce the impact of project operations on air quality below a level of significance. This impact is therefore significant and unmitigated with implementation of the proposed project. 63 Construction Emission Impacts Impact: · Construction emissions would result in a significant air quality impact. [SEIR, Subchapter 4.8, pp, 355.357] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: The construction of the proposed project would result in the generation of construction equipment exhaust emissions, potentially resulting in a significant air quality impact. Construction activities are projected to generate sufficient quantities of fugitive dust to create a significant impact. Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of significance. The infeasibility of the No Project alternative is described in Section XI of these findings. Mitigation Measures: the following construction mitigation measures for the proposed project will reduce air quality impacts and shall be included as conditions of approval of Fading and building permits issued for future tentative maps and shall be the responsibility of the applicant. [SEIR, Subchapter 4.8, pp. 361-362] 4.8.5.1 All unpaved construction areas shall be watered at least twice daily or have other acceptable San Diego APCD dust control agents applied during dust-generating activities to reduce dust emissions. Additional watering or acceptable APCD dust control agents shall be applied during dry weather or windy days to prevent visible dust emissions. 4.8.5.2 Tracks hauling din and debris shall be properly covered to reduce windblown dust and spills. 4.8.5.3A 20-mile-per-hour speed limit shall be posted on all unpaved roadways used by construction vehicles. 4.8.5.4 On dry days, din and debris spilled onto paved surfaces shall be swept up immediately to reduce resuspension of particulate matter caused by vehicle movement. Approach routes to conslruction sites shall be cleaned daily of construction-related dirt in dry weather. 4.8.5.5 On-site stockpiles of excavated material shall be covered or watered. 64 4.8.5.6 Disturbed areas shall be hydroseeded, landscaped, or developed as quickly as possible and as directed by the City to reduce dust generation. 4.8.5.7Heavy-duty construction equipment with modified combustion/fuel injection systems for emissions control shall be utilized during Fading and construction activities. Catalytic reduction for gasoline-powered equipment shall be used. Also, equip construction equipment with prechamber diesel en~nes (or equivalent) together with proper maintenance and operation to reduce emissions of nitrogen oxide, to the extent available and feasible. 4.8.5.8 Low pollutant-emitting construction equipment shall be used. 4.8.5.9 Electrical construction equipment shall be used to the extent feasible. 4.8.5.10The simultaneous operations of multiple construction equipment units shall be minimized (i.e., phase construction to minimize impacts). Significance After Mitigation: The mitigation measures will reduce short-term impacts from dust and emissions, but not below a level of significance. Construction-related impacts to air quality are therefore significant and unmitigated. Panhandle Site Impact: Construction on the Panhandle site and project operations could significantly impact air quality. [SEIR, Subchapter 4.8, pp. 357,359] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: Construction on the Panhandle site and project operations could significantly impact air quality depending on the proposed land use. Project operations- related emissions, including those from stationary and mobile sources, could exceed SCAQMD thresholds, depending on the proposed land use, therefore, could result in a potentially significant redonat impact on air quality. The construction of the proposed project would result in the generation of construction equipment exhaust emissions, potentially resulting in a significant air quality impact. Construction activities also generate furtive dust, which may create a si~ificant impact. 65 Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of significance. The infeasibiliv,.' of the No Project alternative is described in Section XI of these findings. Mitigation Measures: The following mitigation measures will reduce air quality impacts and shall be included as conditions of approval of grading and building permits issued for future tentative maps and shall be the responsibility of the applicant. [SEIR, Subchapter 4.8, page 362] 4.8.5.11 Detailed mitigation for air quality impacts at the Panhandle site shall be required at the time development plans are proposed. Mitigation for impacts at the Panhandle site would consist of application of construction-emission mitigation measures similar to that described above. Significance After Mitigation: The mitigation measures will reduce impacts from construction and project operations on the Panhandle site, but not below a level of significance. Impacts to air quality are therefore significant and unmitigated. I. CULTURAL RESOURCES Standards of Significance: The proposed project would have a significant impact on cultural resources if it: · Diminishes the historical integrity of a significant historic resource, which is defined as a resource that is: 1 ) On or eligible for the California Register of Historic Resources; 2) On or eligible for the National Register ofHistoric Places; 3)Locally designated as historically si~.~ficant; and/or the lead agency finds the resource historically significant based on substantial evidence: or · Darnages or destroys a unique archeological resource, which is defined as a resource that: 1) Is associated with an event or person of recognized significance in California or American history or recognized scientific importance in prehistory; 2) Can provide information that is of demonstrable public interest and is useful in addressing scientifically consequential and reasonable research questions; 66 3)Has a special or particular quality such as the oldest. best example~ largest. or last surviving example of its kind; 4) Is at least 100 years old and possesses substantial stratigraphic integrity; and/or involves important research questions that historical research has shown can be answered only with archaeological methods. Impact: · Development of the proposed project could adversely affect cultural resources.[SEIR, Subchapter 4.9, pp. 368-369] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of si~_~dficance. Explanation: The proposed development of the Woods parcel would result in direct and indirect impacts to CA-SDI~7976. Site CA-SDI-7976 exists on land designated for low- density residential land use along with a small area of open space in the Woods. Development of the Woods parcel would constitute a direct and potentially significant impact to this pre-historic resource. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.9, page 371 ] 4.9.5.1 Prior to the issuance of a ~ading permit for the Woods, the applicant must receive approval from the Director of Planning for a treatment pro~am for site CA-SDI-7976 consisting of a research design, data recovery plan, analysis, and report. The research design and data recovery pro~am shall be oriented towards addressing re~onally important research questions. The research design for CA-SDI 7976 should be developed prior to the implementation of the data recovery excavations. It should include rnethodolo~cal statements and provisions for incorporating special studies (i.e., radiocarbon dating) as well as the specifics of the theoretical orientation, and the research questions themselves. The results of the data recovery effort must be summarized in a report that includes the research design, results of the investigation, discussion of the issues and findings, and includes the raw data generated during the investigation. In addition, no development should occur on the site location or vicinity until the data recovery investigation has been completed. Once the archaeolo~cal 67 consultant is satisfied that sufficient dam have been acquired from the site to answer the research questions and that redundant dam would be generated by additional field investigation, the site may be released for development. Significance After Mitigation: Less than significant Panhandle Site Impact: · Development of the Panhandle site could adversely affect cultural resources. [SEll>,, Subchapter 4.9, page 369] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the sig~nificant environmental effect as identified in the SEIR below a level of significance. Explanation: Of the eight prehistoric cultural resources on the Panhandle site, four are cultural isolates and do not meet the criteria of significance under CEQA. No additional recording or evaluation effort is recommended for the cultural isolates in the Panhandle site. The four lithie scatter sites at the Panhandle have not been evaluated for cultural resource significance under CEQA, and therefore the impact is considered significant. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.9, page 371 ] 4.9.5.2 Prior to any development plans for the Panhandle site, testing of the four lithic scatter sites shall be conducted to determine significance. A qualified archaeologist/cultural resource specialist shall conduct a site testing investigation for the four lithic scatter sites on the Panhandle to determine if any of the affected sites meet the si~tificance criteria under CEQA. The project proponent shall submit the results of the testing proFaro to the City of Chula Vista prior to commencement of clearing, grubbing, or ~ading activities for the Panhandle site. The testing pro~am for each site shall consist of mapping, a surface collection, surface scrapes, and subsurface test probes. Following site testing investigation, the qualified archaeologist/cultural resource specialist shall analyze recovered cultural material and a summary report shall be prepared and submitted to the City of Chula Vista. The summary report shall document the 68 significance assessment investigations for the four lithic scatter sites and make any necessary recommendations for impact mitigation. J. PALEONTOLOGICAL RESOURCES Standards of Significance: The proposed project would have a significant impact on paleontological resources if it: · Directly or indirectly destroys a unique paleontological resource or site. Impact: · Development of the proposed project could impact paleontolo~cal resources. [SEIR, Subchapter 4.9, page 370] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of si~mificance. Explanation: Impacts to paleontolo~cal resources occur when earthwork activities cut into geological formations and destroy the buried fossil remains. Areas of the Otay Formation may be exposed during Fading and construction activities. Exposure of this formation would likely disturb fossil remains in the Vistas and the Woods. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.9, pp. 372-373] 4.9.5.3 Prior to issuance of a ~ading permit, the applicant shall confirm in writing to the City of Chula Vista that a qualified paleontologist has been retained to carry out the mitigation described herein. A qualified paleontolo~st is defined as an individual with a M.S. or Ph.D. in paleontology or geology who is familiar with paleontological procedures and techniques. A paleontological monitor may be retained to perform the on-site monitoring in place of the qualified paleontologist. A paleontological monitor is defined as an individual who has experience in the collection and salvage of fossil materials and who is working under the supervision of a qualified paleontologist. 4.9.5.4 The qualified paleontolo~st or paleontolo~cal monitor shall attend a preconstmction meeting to consult with the gading and excavation 69 contractors. The paleontolo~st's duties shall include monitoring of ~ading, salvaging, preparation of collected materials for storage at a scientific institution that houses paleontological collections, and preparation of a monitoring results report. For each step listed below, the paleontologist should present results to the City of Chula Vista for review. These duties are defined as follows: a) The paleontologiist or paleontological monitor shall be on-site during the original cutting of previously undisturbed sediments of the Otay Formation to inspect cuts for fossils contained therein. The Sweetwater Fonnation should be monitored on an as-needed basis as determined by the paleontolo~st or paleontological monitor. The frequency of inspections would depend upon the rate of excavation, the materials excavated, and the abundance of fossils. The paleontologist would work with the contractor to determine the monitoring locations and amount of time necessary to ensure adequate monitoring of the project site. b) In the event that fossils are encountered, the paleontologist (or paleontolo~cal monitor) shall have the authority to divert or temporarily halt construction activities in the area of discovery to allow recovery of fossil remains in a timely fashion. Because of the potential for recovery of small fossil remains, it may be necessary to set up a screen-washing operation on-site. c) Fossil remains shall be cleaned, sorted~ repaired, cataloged, and then stored in a local scientific institution that houses paleontolo~cal collections, such as the San Diego Natural History Museum. d) A monitoring results report with appropriate graphics summarizing the results (even if negative), analyses, and conclusions of the above program shall be prepared and submitted to the City of Chula Vista within 90 days following the termination of the paleontological monitoring program. Significance After Mitigation: Less than significant 7O Panhandle Site Impact: · Development of the Parthandle site could impact paleontolo~cal resources. [SEIR, Subchapter 4.9, page 370] Finding: Pursuant to section 15091(a)(1 ) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into. the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of sig, nificance. Explanation: impacts to paleontological resources occur when earthwork activities cut into geological formations and destroy the buried fossil remains. Areas of the Otay Formation may be exposed during grading and construction activities. Exposure of this formation would likely disturb fossil remains. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.9, page 373] 4.9.5.5 Prior to issuance of a grading permit for future development of the Panhandle site, the applicant shall confirm in writing to the City of Chula Vista that a qualified paleontologist has been retained to carry out the mitigation described herein. As with the Woods and Vistas, the qualified paleontologist or paleontolo~cal monitor shall attend pre-construction meeting to consult with the grading and excavation contractors. The paleontolo~st's duties shall include monitoring of grading, salvaging, preparation of collected materials for storage at a scientific institution that houses paieontological collections, and preparation of a monitoring results report. The paleontolo~st should present results to the City of Chula Vista for review. Significance After Mitigation: Less than significant K. PUBLIC FACILITIES POTABLE WATER Standards of Significance: The proposed project would have a significant impact on potable water if it: 71 · Encourages activities which result in the use of large amounts of water, or use of water in a wasteful manner; · Results in substantial need for new. altered, or expanded services; or · Contributes to a capacity deficiency in a re~onal facility. Impact: · The proposed project could result in significant impacts to potable water supply and storage.[SEIR, Subchapter 4.10, pp. 378, 380-381] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~..onificant environmental effect as identified in the SEIR below a level of significance. Explanation: The proposed project would result in an incremental increase in water consumption and place additional demands on water storage and pumping facilities. The projected Average Annual Demand for EastLake I13[ 980 Zone and 711 Zone is 912,069 gpd and i00~872 gpd, respectively, for a total of 1.012,941 gpd (including the Panhandle site). Preliminary domestic water demand for the EastLake III SPA was also determined as part of the Subarea Water Master Plan process and estimamcl at 953,355 gallons per average day (0.95 mgd), not including the Panhandle site. The increase in potable water demand has been planned for by the Otay Water District and will not have a significant impact. Storage requirements for the 980 and 711 Zones are 15.97 mgd and 14.63 mgd, respectively. The existing operational storage requirement for the 980 Zone is 10.00 mg and is 5.0 mg 711 Zone. The OWD is curren~y processing storage capacity upgrades in the 980 and 711 Zones. However, the impact to water storage and pumping facilities could be sigttificant if construction of new facilities does not coincide with the project's anticipated growth. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR. Subchapter 4.10, page 382] 4.10.l.1 The applicant shall help provide for adequate potable water storage and distribution facilities, which shall be constructed in accordance with the Subarea Master Plan and to the satisfaction of the OWD. These water infrastructure improvements are also described in the proposed Public Facilities Financing Plans for EastLake 1II. The proposed PFFP identifies the development impact fees that the applicant shall pay to mitigate impacts, the estimated cost of the facility, the applicant's obligation to construct andjor pay for the necessary mitigation, and the phasing improvements. Prior to approval of the first Final Map, the applicant shall provide written proof from OWD that adequate water storage and distribution facilities are available to serve the proposed project area. 4.10.1.2 A complete Subarea Master Plan shall be submitted to the City for review and approved by OWD prior to approval of the first tentative map. The Master Plan shall include the design of water system facilities including timing and cost by phase of development. Significance After Mitigation: Less than significant Panhandle Site Impact: · Development of the Panhandle Site could result in significant impacts to potable water supply and storage. [SEIR, Subchapter 4.10, page 381 ] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into. the project that will substantially lessen or avoid the si~-mificant environmental effect as identified in the SEIR below a level of significance. Explanation: Development of the Panhandle Site would result in an incremental increase in water demand, thereby potentially impacting water storage and conveyance facilities. In calculating the project demand, the SAMP assumed that the Panhandle site has an underlying alternate land use of low density residential (2.0 dwelling units/acre), resulting in a unit demand of 1,339 gpd/acre and a demand of 59,586 gpd. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 383] 4.10.1.3 At the time detailed development plans are proposed at the Panhandle site, the project applicant shall help provide for adequate potable water storage and distribution facilities for the Panhandle site, which shall be constructed in accordance with the Subarea Master Plan and to the satisfaction of the OWD. A complete Subarea Master Plan shall be submitted to the City for review and approved by OWD prior to approval of any development plans. As with the Woods and Vistas 73 above, the Master Plan shall include the design of water system facilities " including timing and cost by phase of development. Significance After Mitigation: Less than significant RECYCLED WATER Standards of Significance: The proposed project would have a significant impact on recycled water service if it: · Encourages activities that result in the use of large amounts of recycled water, or use recycled water in a wasteful manner; Results in substantial need for new, altered, or expanded services Contributes to a capacity deficiency in a redonat facility; or · Creates a public health risk. Impact: The proposed project could result in significant impacts to recycled water supply and storage. [SEIR, Subchapter 4.10, pp. 384, 387] Finding: Pursuant to section 15091(a)(I) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~_~Lificant environmental effect as identified in the SEIR below a level of significance. Explanation: The proposed project would result in an incremental increase in recycled water use and place additional demands on water storage and pumping facilities. Recycled water demand for EastLake 1]I was calculated at a dally average of 352,953 gallons (0.35 mgd) in the Preliminary SAMP. The largest user of recycled water identified in the Preliminary SAMP is irrigated open space, followed distantly by public parks and landscaping within the multi-family residential areas. The increase in recycled water demand has been planned for by the OWD and will not have a significant impact. The impact to recycled water storage and pumping facilities could be significant if construction of new facilities does not coincide with the project's anticipated ~owth. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR. Subchapter 4.10, pp. 387-388] 74 4.10.2.1 The applicant shall help provide for adequate recycled water storage and distribution facilities; which shall be constructed in accordance with the Subarea Master Plan and to the satisfaction of the OWD. These water infrastructure improvements are described in the proposed Public Facilities Financing Plans for EastLake 1II. The proposed PFFP identifies the development impact fees that the applicant shall pay to mitigate impacts, the estimated cost of the facility, the applicant's obligation to construct and/or pay for the necessary mitigation, and the phasing improvements. Prior to approval of the first Final Map, the applicant would provide written proof from OWD that adequate water storage and distribution facilities are available to serve the proposed project area. 4.10.2.2 A complete Subarea Master Plan shall be required for approval prior to approval of the tentative map. The recycled water system shall be designed at that time and the timing and cost shall be identified by phase of development. Significance After Mitigation: Less than significant Panhandle Site Impact: · Development of the Panhandle site could result in si~cmificant impacts to recycled water supply and storage if the site is irrigated with potable water [SEIR, Subchapter 4.10, page 387] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of sig~nificance. Explanation: The SAMP analysis assumes the Panhandle site will be irrigated with potable water. However, if it is decided that recycled water should be used for irrigation, development of the Panhandle site would incrementally increase the demand for recycled water, thereby potentially impacting recycled water storage and conveyance facilities. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 388] 75 4.10.2.3 If during the processing of detailed development plans for the Panhandle site it is determined that the Panhandle site is to be irrigated with recycled water, the project applicant shall help provide for adequate recycled water storage and distribution facilities for the Panhandle site. The facilities shall be constructed in accordance with the Subarea Master Plan and to the satisfaction of the OWD. A complete Subarea Master Plan shall be required prior to approval of any development plans. The recycled water system shall be designed at that time and the timing and cost shall be identified by phase of development. Significance After Mitigation: Less than significant SEWER Standards of Significance: The proposed project would have a significant impact on sewer service it if: · Results in substantial need for new, altered, or expanded services; · Contributes to a capacity deficiency in a redonat facility; · Creates a public health risk: or · Exceeds City Engineering Standards. Impact: · Development of the proposed project could result in significant impacts to sewer services [SEIR, Subchapter 4.10, pp. 391-392] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of sig~tificance. Explanation: Development of the proposed project would result in an incremental increase in sewage generation. The EastLake l]l Preliminary. Sewer Study estimated an average sewage generation rate of 720,332 gpd or 688,032 gpd, with the Panhandle sewage generation calculations based on commercial/industrial or residential uses, respectively, which does not exceed the City's remaining capacity at Metro. This increase could cause a significant impact if construction of new infrastructure does not coincide with the project's anticipated development. If the Salt Creek Interceptor is not completed 76 prior to consideration of the tentative map, wastewater shall be temporarily pumped to facilities in Telegraph Canyon and/or Pog~ Canyon. Mitigation Measure: The following rmtigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.1 O, pp. 401402] 4.10.3.1 The applicant shall be responsible for a development impact fee imposed on the proposed developments within the Salt Creek Sewer Basin for consauction of the Salt Creek Interceptor. The phased construction of sewer facilities and/or participation in redohal improvement programs, based on the approved master plan, shall be incorporated into the PFFP and/or subdivision map conditions to assure timely provision of required facilities. The applicant shall comply with the sewer mitigation measures as described in the proposed PFFP, including public facilities fees, payment schedule by the developer, and timing of sewer improvements. 4.10.3.2 Prior to approval of any final map or any other grant of approval for any improvement proposing to pump EastLake HI sewage flows to the Telegraph Canyon and/or Poggi Canyon sewer trunks, the City Engineer, at his/her sole discretion, shall determine the extent of those improvements needed for pumping EastLake HI sewage flows consistent with 1) the requirements of City Policy No. 570-03, 2) the Preliminary Offsite Sewer Study for EastLake HI prepared by John Powell & Associates Inc. dated November 2000 and revised January 3, 2001 (see Attachment I of Subsequent EIR 01-01 ) and 3) the City Memorandum dated February 19, 2001 (see Attachment I of Subsequent EIR 01-01). Hows from no more than 1,610 Equivalent Dwelling Units shall be pumped to Telegraph Canyon and/or Pog~ Canyon, as described in the Preliminary Offsite Sewer Study for EastLake Significance After Mitigation: Less than sigv. i~cant Panhandle Site Impact: · Development of the Panhandle site could result in si~mai~cant impacts to sewer services [SEIR, S ubchapter 4.10, pp. 400-401 ] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen 77 or avoid the significant environmental effect as identified in the SEIR below a level of ' significance. Explanation: Wastewater generation from Panhandle site development would require conveyance facilities and potentially impact the City's sewer system and treatment capacity. With a 44-acre area, a commercial/industrial site, with average sewage production of 2,500 gpd/acre, would produce 88,000 gpd. A 4-4-acre residential area (assuming 6 du/ac and 3.3 persons/unit), with average sewage production of 80 gpd, would produce 55,700 gpd. Temporarily pumping flows from the site could exceed available capacity in the sewage conveyance systems in the Poggi Canyon Basin or Telegraph Canyon Basins, resulting in a significant impact. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, pp. 402-403] 4.10.3.4 At the time detailed development plans are proposed, a sewer study shall be prepared to identify wastewater generation, required transmission facilities, and any treatment capacity issues. Based on the study, appropriate mitigation shall be required, which could include on-and off- site infrastructure upgrades and related development phasing. Significance After Mitigation: Less than significant PARKS AND RECREATION Standards of Significance: The proposed project would have a significant impact on park and recreational facilities if it: · Results in a residential population that exceeds the capacity of existing and/or planned park and recreation facilities: · Does not conform to the park dedication standard of three acres of neighborhood and community parkland per 1,000 residents; or · Is inconsistent with the goals and policies of the General Plan and other adopted plans addressing parks, trails, and other recreational amenities. 78 Panhandle Site Impact: · Development of the Panhandle site could result in significant impacts to parks and recreation resources. [SEIR, Subchapter 4.10, page 409] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~_onificant environmental effect as identified in the SEIR below a level of significance. Explanation: If the Panhandle site is developed for residential use, it would be subject to the City's parkland dedication requirements and evaluated against the GMOC threshold standards for park acreage. Should the Panhandle site be developed with low density residential uses, potentially significant impacts to park and recreation facilities could occur. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4. t 0, page 410] 4.10.5.1 As a condition of approval of detailed development plans at the Panhandle site, the project shall comply with the City of Chula Vista' s local parkland requirements as set forth by the City Parkland Dedication Ordinance. Significance After Mitigation: Less than significant POLICE Standards of Significance: The proposed project would have a significant impact on police services if it: · Reduces the ability to respond to Priority I emergency calls throughout the City within seven minutes in 84 percent of the cases, and maintain an average response time to all Priority I calls of 4.5 minutes or less. 79 Impact: o The project would cause an incremental increase in calls for police services. [SEER. Subchapter 4.10. page 412] Finding: Pursuant to section 15091(a)(I) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: The Police Department currently fails to meet the threshold standards for Priority One and Priority Two calls. Development of the proposed project would result in an incremental increase in calls for police service. Giyen the location of EastLake 1311, officers would be required to travel additional distances to respond to calls for service, and increased travel time consequently lengthens response time, thus exacerbating an already significant impact. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [ SEER, S ubchapter 4.10, page 413 ] 4.10.6.1 Significant impacts to police services shall be addressed on a citywide level through the payment of public facility fees. The proposed EastLake I]I PFFP describes public facilities fees for police services based on equivalent dwelling units by development phase. Prior to the issuance of building pennits, the applicant shall pay the public facilities fees at the rate in effect at the time building permits are issued. Panhandle Site Impact: · Development of the Panhandle site would cause an incremental increase in calls for police services. [SEER, Subchapter 4.10, page 412] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the si~,mificant environmental effect as identified in the SEIR below a level of significance. Explanation: The Police Department currently falls to meet the threshold standards for Priority One and Priority Two calls. Development of the Panhandle site would result in an incremental increase in calls for police service. Given the location of the site, officers 8O would be required to travel additional distances to respond to calls for service, and increased travel time consequently lengthens response time. thus exacerbating an already si~maificant impact. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 413 ] 4.10.6.2 As a condition of approval of any detailed development plans for the Panhandle site, the project applicant shall pay public facility fees at the rate in effect the building permits are issued. FIRE Standards of Significance: The proposed project would have a significant impact on fire protection services if it: · Reduces the ability to respond to calls throu,,hout the City within seven minutes in 85 percent of the cases. Impact: · The project would increase the demand for fire services. [SEIR, Subchapter 4.10, pp. 414-415] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of sigqni~cance. Explanation: The Fire Department currently exceeds the threshold standards established for response time. Increased response time is attributable, in part, to increased travel time, which results from responding to freeway incidents, and the lower density, hilly terrain, and the more circuitous non-grid nature of many streets in new residential developments in eastern Chula Vista. The project would therefore cause a significant short-term impact to fire services. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 415] 81 4.10.7.1 Significant impacts to fire sen:ices shall be addressed on a citywide level through the pa,vment of public facility fees. The proposed EastLake HI P~k,e describes public facilities fees for fire services based on equivalent dwelling units by development phase. Prior to the issuance of building permits, the applicant shall pay the public facilities fees at the rate in effect at the time building permits are issued. Significance After Mitigation: Less than significant Panhandle Site Impact: · The project would increase the demand for fire services and could contribute to cause an increase in response time for the Fire Department. [SEIR, Subchapter 4.10, page 415] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines. changes or alterations are required in, or incorporated into, the project that will substantially lessen or avoid the significant environmental effect as identified in the SEIR below a level of significance. Explanation: The Fire Department currently exceeds the threshold standards established for response time. Increased response time is attributable, in part, to increased travel time, which results from responding to freeway incidents, and the lower density, hilly terrain, and the more circuitous non-gild nature of many streets in new residential developments in eastern Chula Vista. Development of the Panhandle site would place additional demands on the Chula Vista Fire Department and would therefore cause a significant short-term impact to fire services. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 415] 4.10.7.2 As a condition of approval of any detailed development plans for the Panhandle site, the project applicant shall pay public facility fees at the rate in effect the building permits are issues. Significance After Mitigation: Less than significant These findings discuss all direct project impacts contained in the SEIR and discussed at public hearings. However, to the extent that an impact or "alleged" impact of the project either direct or secondary has not been discussed in this document, the City Council hereby overrides such impact for the reasons described in the Statement of Overriding Considerations. CLrMULATIVE SIGNIFICANT EFbECTS AND MITIGATION MEASURES Cumulative impacts are those which "are considered when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects" (Pub. Resources Code section 21082.2, subd. (b)). Several development proposals have been submitted for consideration or have been recently approved by the Cities of Chula Vista and San Diego and the County of San Diego in proximity to EastLake III. These "current or probable future" development proposals would affect many of the same natural resources and public infrastructure as EastLake Woods and Vistas Replanning Program. Several potentially significant cumulative impacts are associated with development of EastLake Woods and Vistas in conjunction with these surrounding development projects. In formulating mitigation measures for the project, redohal issues and cumulative impacts have been taken into consideration. Many of the mitigation measures adopted for the cumulative impacts are similar to the project level mitigation measures. This reflects the inability of the Lead Agency to impose mitigation measures on surrounding jurisdictions (i.e.. City of San Diego, City of National City, Caltrans, and Mexico) and the contribution of these jurisdictions to cumulative impacts. The project along with the other related projects will result in the following irreversible cumulative environmental changes. All page numbers following the impacts refer to pages from the SEIR. A. TRANSPORTATION/TRAFFIC CIRCULATION Impact: · The proposed project would conlribute to significant cumulative traffic impacts on Olympic Parkway from SR-125 to EastLake Parkway. [SEIR, Subchapter 4.2, pp. 181-182, 186, 190, 195] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will substantially avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. 83 Explanation: Under Year 2010 with SR-125. Ol.vmpic Parkway from SR-125 to EastLake Parkway would operate at LOS E with project implementation in the long-term. Revision to mitigation measure 4.2.5.3 clarifies the timing and manner of mitigation implementation. After further analysis, it was determined that achievement of eight lanes through a new Circulation Element street categor.v "Enhanced Prime Arterial" would be more consistent with General Plan goals and policies than an "Eight-Lane Prime Arterial." Therefore, the street seg~nent category will be renamed in the General Plan Amendment accordingly. As discussed in the FEIR, the cumulative impact to this segncnent of Olympic Parkway will not occur until 2010. Therefore, amending the General Plan in 2002 will allow for the improvement to be made before the impact occurs. These revisions are reflected in replacement pages in the FEIR and MMRP. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the hpplicant through these findings. [SEIR, Subchapter 4.2, page 204] 4.2.5.3 The General Plan shall be amended to designate Olympic Parkway from SR-125 to EastLake Parkway as an Enhanced Prime Arterial with eight lanes. The required amendment shall be adopted no later than the fn'st General Plan Amendment considered for adoption in 2002. The applicant shall contribute a fair share towards the construction of the two additional lanes. Significance After Mitigation: Less than significant Impact: · The proposed project would contribute to significant cumulative traffic impacts on Otay Lakes Road from SR-125 to EastLake Parkway. [SEIR, Subchapter 4.2, pp. 186. 190, 195] Finding: Pursum~t to section 15091 (a)(l) of the St, ate CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant enviromnental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: Under the Year 2020, Otay Lakes Road from SR-125 to EastLake Parkway would operate at LOS D in the long-term with project implementation. Revision to mitigation measure 4.2.5.4 clarifies the timing and manner of mitigation implementation. After further analysis, it was determined that achievement of seven lanes through a new Circulation Element street category "Enhanced Prime Arterial" would be more consistent with General Plan goals and policies than a "Seven-Lane Prime Arterial." Therefore, the 84 street seg~nent category will be renamed in the General Plan Amendment accordingly. As discussed in the HEIR, the cumulative impact to this segment of Otay Lakes Road will not occur until 2020. Therefore. amending the General Plan in 2002 will allow for the improvement to be made before the impact occurs. These revisions are reflected in replacement pages in the FEIR and MMRP. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, page 204] 4.2.5.4 The General Plan shall be amended to designate Otay Lakes Road from SR-125 to EastLake Parkway as an Enhanced Prime Arterial with seven lanes. The required amendment shall be adopted no later than the first General Plan Amendment considered for adoption in 2002. The applicant shall contribute a fair share towards the construction of the additional (westbound) lane. Significance After Mitigation: Less than significant Impact: · The proposed project would contribute to significant cumulative traffic impacts on Otay Lakes Road from H Street to Telegraph Canyon Road. [SEIR, Subchapter 4.2, pp. 169, 181,182, 186] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the si~cmificant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: Under the year 20t0, Otay Lakes Road from H Street to Telegraph Canyon Road would operate at LOS D for more than 2 hours or LOS E/F for 1 hour in the near- term and LOS D, E, and/or F in the long-term with project implementation. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.2, page 204] 4.2.5.5 The applicant shall contribute a fair share towards widening this roadway seg~nent to six lanes or towards intersection improvements that provide additional capacity along Otay Lakes Road to the satisfaction of the City En~neer. 85 Significance After Mitigation: Less than significant Impact: · The proposed project would contribute to significant cumulative traffic impacts on Otay Lakes Road from Bonita Road to H Street. [SEIR, Subchapter 4.10, pp. 169, 181-182, 186] Finding: Pursuant to section 15091 (a)(I) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: Under Year 2005 without SR-125, Otay Lakes Road from Bonita Road to H Street would operate at LOS F in the long-term with project implementation. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, pp. 204-205] 4.2.5.6 The applicant shall contribute a fair share towards widening Otay Lakes Road from Bonita Road to H Sn'eet to six lanes or towards intersection improvements that provide additional capacity along Otay Lakes Road to the satisfaction of the City Engineer. Significance After Mitigation: Less than si~kmificant Impact: · If more than 9,429 new dwelling units are constructed, a significant impact is calculated on Tele~aph Canyon Road as well as other streets in the near-term cumulative scenario, including: · East H Street/I-805 northbound ramps · East H Street/Hidden Vista Drive · Telegraph Canyon Roadfl-805 southbound ramps · Telegraph Canyon Road/I-805 northbound ramps [SEER, Subchapter 4.2, page 1613 86 Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines. changes or alterations are required in, or incorporated into, the project that will avoid the si~nificant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate sig~nificant impacts below a level of significance. Explanation: LOS D on Telegraph Canyon Road as well as other streets in the near-term cumulative scenario would not be maintained if over 9,429 total units are built and SR- i25 is not constructed. City standards will therefore be exceeded on Telegraph Canyon Road and the other segrnents listed above, resulting in a significant impact. The impact was calculated to occur when the total number of dwelling units in the eastern territories exceeds 9,429 units. This dwelling unit threshold is considered to be accurate within +20 percent. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 205] 4.2.5.7 Prior to the construction of SR-125, the City shall stop issuing new building permits for EastLake HI when the City, in its sole discretion, determines either: a) Building permits for a total of 9,429 dwelling units have been issued for projects east of 1-805 or; b) An alternative measure is selected by the City in accordance with the City of Chula Vista Growth Management Ordinance. The start date for counting the 9,429 dwelling units is January 1, 2000. Notwithstanding the foregoing, the City may issue building permits if the City decides in its sole discretion that either traffic studies demonstrate, to the satisfaction of the City Engineer, that the circulation system has additional capacity without exceeding the Growth Management Oversight Committee traffic threshold standards, other improvements are constructed which provide additional necessary capacity, or the City selects an alternative method of implementing the Growth Management Oversight Committee standards. These traffic studies would not require additional environmental review under CEQA; however, any improvements proposed in these traffic studies would be subject to additional environmental review as needed. Significance After Mitigation: Less than significant 87 Impact: · The proposed project would contribute to significant cumulative traffic impacts on 1-805 from Bonita Road to Telegraph Canyon Road, [SEIR, Subchapter 4.10, pp. 169, 177, 182, 190, 195] Finding: Pursuant to section 15091 (a)(l) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: 1-805 from Bonita Road to Telegraph Canyon Road is expected to operate at LOS F in the Year 2005 with and without SR-125.1-805 is also calculated to operate at LOS F at buildout. Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of sig'nificance. The infeasibility of the No Project alternative is described in Section XI of these findings. Mitigation Measures: The following mitigation measures are designed to reduce the traffic impacts on 1-805 from Bonita Road to Telegraph Canyon Road and are a requirement of project approval. [SEIR, Subchapter 4.10. page 205] "- 4.2.5.8Additional lanes are required to maintain acceptable LOS on 1-805 between Bonita Road and Telegraph Canyon Road. Construction of the additional lanes is the responsibility of Caltrans. 4.2.5.9 Continued freeway efforts and deficiency planning by Caltrans and SANDAG shall determine additional mitigation strate~es for the re~onal freeway system. Significance After Mitigation: These mitigation measures will reduce this cumulative effect, but not below a level of significance. The traffic impact on 1-805 from Bonita Road to Telegraph Car~yon Road remains significant and unmitigated. Secondarx.' Impacts Associated .,ith Off-Site Traffic Mitigation Improvements Impact: · The off-site traffic improvements to Olympic Parkway and Otay Lakes Road could create secondary impacts. [SEtR, Subchapter 4.10, pp. 207-209] Finding: Pursuant to section 15091(a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into~ the project that will avoid the significant 88 environmentai effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: Off-site traffic improvements to Olympic Parkway and Otay Lakes Road could create secondary impacts associated with land use, biological resources, construction-related water quality impacts, construction-related traffic impacts (potential land closures, l~affic delays, and hazards), aesthetics/landform alteration, noise, and cultural/paleontological resources. Depending on the detailed design of the off-site traffic improvements to the above-referenced segments of Olympic Parkway and Otay Lakes Road, additional environmental review may be required. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, pp. 209-210] Application of the following pro~am-level mitigation measures shall be implemented at the discretion of the Planning Director at the time the roadway improvements are proposed to reduce the potential significant impacts to below a level of significance. Depending on the detailed design of the off-site traffic improvements to the above- referenced seg~nents of Olympic Parkway and Otay Lakes Road, additional environmental review may be required. The pro~am-level mitigation measures include the following: 4.2.5.16 Prior to the approval of the roadway improvement project, a biolo~cal reconnaissance based on detailed grading and design plans shall be conducted to document any impacts to sensitive biological habitats and species. Any impacts to sensitive biolo~cal habitats shall be mitigated pursuant to the mitigation ratios described in the City of Chula Vista Subarea Plan. 4.2.5.17 Prior to the issuance of any gading permit for the roadway improve- ment, a detailed acoustical study for the affected roadway segment shall be prepared to determine the need for any noise attenuation measures (such as setbacks, wails, and berms) for adjacent noise sensitive land uses (e.g., residential areas). 4.2.5.18 Prior to the approval of the design plans for the roadway improvements, a detailed landscaping plan shall be prepared to ensure that potential aesthetic impacts associated with any grading necessary for the improvement are mitigated. 89 4.2.5.19 As a condition of any off-site roadway improvement approval, ' monitoring of any grading for the presence of cultural and paleon- tolo~cal resources shall be required. If such resources are encountered during the grading operations, the protocol described in section 4.9 of this EIR shall be required. 4.2.5.20 As a condition of any off-site roadway improvement approval, applicable construction-related water quality mitigation measures shall be required by the City En~neer. These hydrology and water quality mitigation measures are described in section 4.4 of the EIR. 4.2.5.21 As a condition of any off-site roadway improvement approval, preparation of a traffic contTol plan for delays and hazards associated with construction impacts shall be prepared and approved by the City En~neer. For the widening of Otay Lakes Road between H Street and Telegraph Canyon Road, the following mitigation measure shall be required: 4.2.5.22 Plans prepared for the improvement of Otay Lakes Road between H Street and Telegraph Canyon Road shall be designed to avoid impacts to ' the church library. Significance After Mitigation: Less than significant B. HYDROLOGY/DRAINAGE Impact: · The proposed project may contribute to a significant cumulative impact to hydrology and water quality. [SEIR, Chapter 5.0, page 438] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: Under the developed site conditions, potentially significant cumulative water quality impacts could result from runoff flowing across impervious surfaces as well as landscaped areas containing pollutants. Additional cumulative impacts to water quality may result from the use of reclaimed water for on-site irrigation of parks and nonresidential landscape. Development of the proposed project together with other 90 anticipated projects in the Otay Lakes Basin and the Salt Creek Drainage Basin could cause an increase in the amount of runoff and have potentially significant cumulative hydrologic impacts on downstream drainage facilities during the 100-year, 50-year, and 10-year storm events. This and other projects could also pose potentially significant cumulative impacts to wetlands and uplands habitats in those drainage basins. However, those impacts will be reduced through the implementation of best management practices and effective mitigation measures such as those applicable to this project. The City will require the implementation of such measures for other projects that might contribute to this potentially cumulative impact. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.4, pp. 270-274] The project mitigation for direct and indirect impacts to hydrology and water quality would be applicable to potential cumulative hydrological impacts associated with the proposed project. Significance After Mitigation: Less than significant C. LANDFORM ALTERATION/VISUAL QUALIFY Impact: · Project development could result in significant cumulative impacts to landform alteration and visual quality. [SEIR, Chapter 5.0, page 433] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: The City of Chula Vista General Plan, 1989 EastLake 1/I GDP, and GDP EIR anticipate that components of the EastLake I1/project, including the proposed project's Panhandle site and other cumulative projects in the area, would alter and develop the existing landforms and visual setting in the area. Open expanses of rolling hills used for agricultural purposes would be developed with clustered residential and commercial areas separated by open space. Consistent with the conclusions of the previous 1989 EastLake 1II GDP EIR, the project's and other cumulative projects' contributions to open space conversion would represent a sig'nificant cumulative impact. Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of significance. The infeasibility of the No Project alternative is described in Section XI of these findings. 91 Mitigation Measures: The following mitigation measure is designed to reduce cumulative impacts to landfonn alteration and visual quality and is a requirement of project approval. The project mitigation for direct and indirect impacts to landforms and visual quality would be applicable for cumulative impacts to landform alteration and visual quality associated with the proposed project. Significance After Mitigation: The mitigation measures will not reduce this impact below a level of significance. The cumulative impact to landform alternation and visual quality remains significant and unmitigable. D. NOISE Impact: · Cumulative noise levels would not exceed land use compatibility standards if mitigation measures are incorporated. Future development of the Panhandle site with open space/park (as approved) or alternative uses, including a possible public/quasi-public use, would not be expected to contribute to a significant cumulative noise impact in the region. [SEIR, Chapter 5.0, page 437] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable taws and regulations would mitigate significant impacts below a level of significance. Explanation: Ambient noise levels in the project area would increase in association with the proposed project traffic volumes in addition to other noise sources associated with urban activities. Cumulative noise levels from EastLake 1II and other development in the Eastern Territories would not exceed land use compatibility standards if mitigation measures for impacts associated with development as described in Chapter 4.7, are incorporated. Additional mitigation may be required to reduce noise impacts associated with development of the Panhandle site, especially if future public/quasi-public uses are proposed that result in significant lraffic or other noise-generating uses. However, the site is in a relatively isolated location and separated from other sensitive uses. Future development of this site with open space/park (as approved) or alternative uses, including a possible public/quasi-public use, would not be expected to contribute to a significant cumulative noise impact in the region Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.7, pp. 330, 336-337] Project mitigation for direct and indirect noise impacts would be applicable to cumulative noise impacts associated with the proposed project. Significance After Mitigation: Less than significant E. AIR QUALITY Impact: · Project operations could contribute to a significant cumulative impact on regional air quality. [SEIR, Chapter 5.0, pp. 438-439] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the SEIR. Explanation: The San Diego area is a nonattainment basin for ozone. The San Diego Air Pollution Control District is responsible for strategies to reduce air pollution in the air basin and bases its projections of future air quality and pollutant emissions on population and employment growth estimates developed by SANDAG. Incorporation of the mitigation measures in Section 4.8 of the SEIR will reduce air quality impacts, but not below a level of significance. Compliance with regional air pollution rules and regulations will reduce potential short-term construction impacts; howe'~er, these impacts remain significant. Project operations-related emissions, including those from stationary and mobile sources, are projected to exceed SCAQMD thresholds and therefore would result in a potentially significant regional impact on air quality. No mitigation currently exists to reduce this impact below a level of sig'nificance; therefore, project operations- related emissions could contribute to a significant cumulative impact on regional air quality. Implementation of the No Project alternative, as discussed in Chapter 6.0 of the SEIR, would reduce this impact below a level of significance. The infeasibility of the No Project alternative is described in Section XI of these findings. Mitigation Measures: No mitigation is available for cumulative project emissions associated with the proposed project. However, measures have been incorporated into the project design to lessen operational air quality impacts. These measures include pedestrian trails (Chula Vista Greenbelt Trail and EastLake Community Trail), on-street bicycle paths, and public transit stops planned for Hunte Parkway, Olympic Parkway, 93 and/or Otay Lakes Road. Future plans exist for extension of trolley service to the Eastern "-' Territories as well. In addition, the City's Growth Management Ordinance requires preparation of an Air Quality Improvement Plan as pan of the SPA Plan for all major development projects (50 dwelling units or geater). [SEIR, Chapter 5.0, page 439] Significance After Mitigation: These measures are insufficient to reduce the cumulative impact to air quality below a level of significance. The cumulative impact to air quality therefore remains sig"nificant and unmitigated with implementation of the proposed project. F. CULTURAL RESOURCES Impact: · Loss of cultural resources from EastLake III and other projects in the area would represent a cumulative impact. [SEIR, Chapter 5.0, page 439] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would - mitigate significant impacts below a level of significance. Explanation: A significant pre-historic site (CA-SDI-7976) is located in the northeast comer of the project site. A loss of cultural resources from EastLake ~I and other projects in the area would represent a cumulatively significant impact. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.9, page 371] Project mitigation for direct and indirect impacts to cultural resources would apply to cumulative impacts to cultural resources associated with the proposed project. Significance After Mitigation: Less than significant G, PALEON'TOLOGICAL RESOURCES Impact: 94 · A loss of paleontological resources from EastLake III and other projects in the area would represent a cumulative impact. [SEIR, Chapter 5.0, page 439] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the si~tificant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: The EastLake area contains significant paleontological resources. Fossils were recovered from the underlying Otay and Sweetwater Formations in previous EastLake consu'uction and represent a significant contribution to California paleontology. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.9, page 372] Project mitigation for direct and indirect impacts to paleontological resources would apply to cumulative impacts to paleontolo~cal resources associated with the proposed project. Significance After Mitigation: Less than significant H. PUBLIC FACILITIES POTABLE WATER Impact: The proposed project would incrementally increase consumption of potable water. [SEIR, Chapter 5.0, page 437] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the si~nificant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: The proposed project, including future development of the Panhandle site, would incrementally increase re~onal water consumption; however, this increase represents an insignificant impact ~ven current water availability. Also, this increased demand for service has been anticipated and planned for by the City of Chula Vista. The use of reclaimed water for irrigation purposes and the proposed conservation measures for reducing potable water consumption would reduce water consumption and avoid contributing to a significant cumulative impact. 95 Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 382] Project mitigation for direct and indirect impacts to potable water would apply to cumulative impacts to potable water associated with the proposed project. Significance After Mitigation: Less than significant RECYCLED WATER Impact: · The proposed project would incrementally increase regional recycled water use. [SEIR, Chapter 5.0, page 437] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of sigm~cance. Explanation: The proposed project, including future development of the Panhandle site, would incrementally increase regional use of recycled water; however, this increase represents an insignificant impact given current water availability. Also, this increased demand for service has been anticipated and planned for by the City of Chula Vista. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, pp. 387-388] Project mitigation for direct and indirect impacts to recycled water would apply to cumulative impacts to recycled water associated with the proposed project. Significance After Mitigation: Less than significant SEWERS Impact: · The proposed project combined with similar projects in the surrounding area could have a cumulatively significant impact upon the City of Chula Vista's 96 sewer infrastructure. [SEIR, Subchapter 4.10, pp. 392, 395-400: and Chapter 5.0. pp. 437-438] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: Development of the Woods and Vistas would incrementally reduce the capacity at the Point Loma Metro Sewer System. The capacity of the Pog~ Canyon Sewer could be exceeded by cumulative projects prior to completion of the Salt Creek Interceptor. However, due to the large area served by the Metro system and the comparatively small increase generated by the Woods, Vistas and any future use considered for the Panhandle site, the project would not result in a significant impact to redonat sewer services. Also, this increased demand for service has been anticipated and planned for by the City of Chula Vista. The proposed project combined with similar projects in the surrounding area could have a cumulatively significant impact upon the City of Chula Vista's sewer infrastructure if not mitigated through improvements to existing facilities and extension of facilities under existing roadways as described in Chapter 4.10 of the SEIR. These improvements would be made according to City requirements and would reduce the project-specific impacts and the project' s conu-ibution to cumulative impacts to a less than significant level. Mitigation Measures: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 402] 4.10.33 If the Salt Creek Interceptor is not operational at the time of consideration of the Final Maps, then the applicant may temporarily pump wastewater flows to the Pog~ Canyon Basin or Telegraph Canyon Basin. The applicant shall be required to comply with all the requirements of Council Policy No. 570-03 (Sewage Pump Station Financing Policy). In addition to the requirements imposed by said Council Policy, the applicant shall be required to perform the following: Removal of any new or modified pump station and associated improvements to the satisfaction of the City En~neer upon completion of the Salt Creek Sewer Interceptor. Connection of the project by gravity to the Salt Creek Sewer Interceptor to the satisfaction of the City En~neer upon completion of the Salt Creek Sewer Interceptor. 97 · Provide funding for establishing the Pog~ Canyon Pumped Sewer Development Impact Fee. Said Development Impact Fee shall be prepared by the City, as directed by the City Endricer, and approved by City Council prior to approval of the first final map for the project proposing to pump EastLake I11 sewage to the Pog~ Canyon Sewer. · Funding a sewer flows monitoring progam for the Pog~ Canyon Sewer as determined by the City En~neer. Application of the Pog~ Canyon equivalent dwelling unit thresholds identified in the City of Chula Vista Engineering Department Poggi Canyon Trunk Sewer Study (see attachment to SEIR Appendix I) shall be applied to the EastLake 1II project if one of the Pog~ Canyon Basin alternatives is selected. The thresholds for Pog~ Canyon Basin can be amended by the City Engineer if he/she determines in his/her sole discretion, that the EDUs assumption of in-basin flows are such that additional pump flows, beyond what is currently allowed under this EIR, can be accommodated as evidenced by monitoring. Significance After Mitigation: Less than significant POLICE PROTECTION Impact: · The project could cause a cumulatively si~-mificant impact to police services. [SEIR, Subchapter 4.10, page 412] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: The Police Department currently fails to meet the threshold standards for Priority One and Priority Two calls. Development of the proposed project would result in an incremental increase in calls for police service. Given the location of EastLake ~I, officers would be required to travel additional distances to respond to calls for service, and increased travel time consequently lengthens response time, thus exacerbating an already significant impact and contributing to a cumulative impact citywide. 98 Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEIR, Subchapter 4.10, page 4 13] The project mitigation for direct and indirect impacts to police services would be applicable to cumulative impacts to police protection associated with the proposed project. Significance After Mitigation: Less than significant FIRE SERVICES Impact: · The project could contribute to a cumulatively sig-nificant impact to fire services. [ SEIR, S ubchapter 4.10, pp. 414-415 ] Finding: Pursuant to section 15091 (a)(1) of the State CEQA Guidelines, changes or alterations are required in, or incorporated into, the project that will avoid the significant environmental effect as identified in the SEIR. Implementation of the measures described below in addition to adherence with applicable laws and regulations would mitigate significant impacts below a level of significance. Explanation: The Fire Department currently exceeds the threshold standards established for response time. Increased response time is attributable, in pan, to increased travel time, which results from responding to freeway incidents, and the lower density, hilly terrain, and the more circuitous non-grid nature of many streets in new residential developments in eastern Chula Vista such as the proposed project. The project would therefore contribute to a significant cumulative impact to citywide fire services. Mitigation Measure: The following mitigation measures are feasible and are required as a condition of approval and are made binding on the applicant through these findings. [SEll>,, Subchapter 4.10, page 415] The project mitigation for direct and indirect impacts to fire services would be applicable to cumulative impacts to fire services associated with the proposed project. Significance After Mitigation: Less than si~m~j.~cant 99 FEASIBILITY OF POTENTIAL PROJECT ALTERNATIVES Because the project will cause some unavoidable significant environmental effects, as outlined above, the City/County must consider the feasibility of any environmentally superior alternative to the project, as finally approved. The City must evaluate whether one or more of these alternatives could avoid or substantially lessen the unavoidable sig~nificant environmental effects. Where, as in this project, significant environmental effects remain even after application of all feasible mitigation measures identified in the Subsequent El]R, the decisionmakers must evaluate the project alternatives identified in the Subsequent EIR. Under these circumstances, CEQA requires findings on the feasibility of project alternatives. In general, in preparing and adopting findings, a lead agency need not necessarily address feasibility when contemplating the approval of a project with significant impacts. Where the significant impacts can be mitigated to an acceptable (insignificant) level solely by the adoption of mitigation measures, the agency, in drafting its findings, has no obligation to consider the feasibility of environmentally superior alternatives, even if their impacts would be less severe than those of the project as mitigated. Laurel Heights Improvement Association v. Regents of the University of Califomzia (1988) 47 Cal.3d 376 [253 Cal.Rptr. 426]; Laurel Hills Homeowners Association v. City Council (1978) 83 Cal.App.3d 515 [147 Cal. Rptr. 842]; see also Kings CourtO, Farm Bureau v. City of Hanford (1990) 221 Cal.App.3d 692 [270 Cal.Rptr. 650]. Accordingly, for this project, in adopting the findings concerning project alternatives, the City Council considers only those environmental impacts that, for the finally approved project, are si~dficant and cannot be avoided or substantially lessened through mitigation. If project alternatives are feasible, the decisionmakers must adopt a Statement of Overriding Considerations with regard to the project. If there is a feasible alternative to the project, the decisionmakers must decide whether it is environmentally superior to the project. Proposed project alternatives considered must be ones that "could feasibly attain the basic objectives of the project." However, the Guidelines also require an EIR to examine alternatives "capable of eliminating" environmental effects even if these alternatives "would impede to some degree the attainment of the project objectives." [CEQA Guidelines section 15126.] The City has properly considered and reasonably rejected project alternatives as "infeasible" pursuant to CEQA. CEQA provides the following definition of the term "feasible" as it applies to the findings requirement: "Feasible" means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social, and technolo~cal factors." [Pub. Resources Code section 21061.1] The CEQA Guidelines provide a broader definition of 100 "feasibility" that also encompasses "legal" factors. CEQA Guidelines section 15364 states, "The lack of legal powers of an agency to use in imposing an alternative or mitigation measure may be as Feat a limitation as any economic, environmental, social, or technological factor." (See also Citizens of Goleta Valley v. Board of Supervisors (1990) 52 Cal.3d 553, 565 [276 Cal. Rptr. 410].) Accordingly, "feasibility" is a term of art under CEQA and thus may not be afforded a different meaning as may be provided by Webster's dictionary or any other sources. Moreover, Public Resources Code section 21081 governs the "findings" requirement under CEQA with regard to the feasibility of alternatives. Specifically, no public agency shall approve or carry out a project for which an environmental impact report has been certified which identifies one or more significant effects on the environment that would occur if the project is approved or carried out unless the public agency makes one or more of the following findings: (I) "[c]hanges or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant enviromnental effect as identified in the final EIR." [CEQA Guidelines section 15091, subd. (a)( 1 )] (2) "such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency. [CEQA Guidelines section 15091, subd. (a)(2)] (3) "[s]pecific economic, legal, social, technolo~caI. or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the final EIR." [CEQA Guidelines section 15091, suM. (a)(3)] The concept of "feasibility" also encompasses the question of whether a particular alternative or mitigation measure promotes the underlying goals and objectives of a project. (Ci.ty of Del Mar v. Ci.ty of San Diego (1982) 133 Cal.App.3d 410, 417 [183 Cal. Rptr. 898]) '"[F]easibility' under CEQA encompasses 'desirability' to the extent that desirability is based on a reasonable balancing of the relevant economic, environmental, social, and technological factors." (Ibid.; see also Sequoyah Hills Homeo,,ners Assn. v. CiB, of Oakland (1993) 23 Cal.App.4th 704, 715 [29 Cal.Rptr.2d 182]) These findings contrast and compare the alternatives where appropriate in order to demonstrate that the selection of the finally approved project, while still resulting in significant environmental impacts, has substantial environmental, planning, fiscal and other benefits. In rejecting certain alternatives, the decisionmakers have examined the finally approved project objectives and weighed the ability of the various alternatives to 101 meet the objectives. The decisionmakers believe that the project best meets the finally approved project objectives with the least environmental impact. The detailed discussion in Sections IX and X demonstrate that all significant environmental effects of the project but three have been either substantially lessened or avoided through the imposition of existing policies or regulations or by the adoption of additional, formal mitigation measures recommended in the SEIR. The remaining unmitigated impacts are the following: · Air quality (direct and cumulative - conformance with regional plans, construction emissions project operations emissions), · Transportation/traffic circulation (cumulative - 1-805: Bonita Road to Telegraph Canyon Road), and · Landform alteration and visual quality (cumulative - contribution to open space conversion ). Thus, the City can fully satisfy its CEQA obligations by determining whether any alternatives identified in the SEIR are both feasible and environmentally superior with respect to the impacts listed above. (Laurel Hills, supra, 83 Cal.App.3d at 519-527; [147 Cal.Rptr. 842]; Kings Coun.ty FatTn Bureau v. Ci~ of Hanford (1990) 221 Cal.App.3d 692, 730-731 [270 Cai. Rptr. 650]; and Laurel Heights Improvement Association v. Regents of the University of California (1988) 47 Cai.3d 376, 400403 [253 Cal.Rptr. 426].) As the succeeding discussion will show, no identified alternative qualifies as both feasible and environmentally superior with respect to the unmitigated impact. To fully account for these unavoidable significant effects, and the extent to which particular aitematives might or might not be environmentally superior with respect to them, these findings will not focus solely on the impacts listed above, but may also address the environrnental merits of the alternatives with respect to all broad categories of impacts--even though such a far-ran~ng discussion is not required by CEQA. The findings will also assess whether each alternative is feasible in light of the City's objectives for the Project. The City's review of project alternatives is ~ided primarily by the need to reduce potential impacts associated with the Project, while still achieving the basic objectives of the Project. Here, the City's primary objective is to comprehensively plan, coordinate and implement development over a large area. More specific objectives include those previously listed in Section 1]I. 102 A. NO PROJECT ALTERNATIVE Section 15126, subdivision (d)(4), of the CEQA Guidelines require the evaJuation of the "No Project" alternative. Such an alternative "shall discuss the existing conditions, as well as what would be reasonably expected to occur in the foreseeable future if the project were not approved, based on current plans and consistent with available infrastructure and community services." Under the No Project alternative, EastLake 1II Vistas and Woods would remain essentially in their existing undeveloped condition. The impacts associated with project implementation and the potentially significant cumulative impacts of proposed and approved developments in the area would not occur under this scenario. The No Project alternative would thus nullify impacts to aesthetics, agricultural resources, air quality, biological resources, cultural/paleontological resources, geology/geologic hazards, hydrology, land use, noise, public facilities, traffic/circulation, and utilities/service systems. However, EastLake I/I, as part of the City of Chula Vista's General Plan and adopted EastLake ffI GDP, is an area planned for development, and it is likely that similar development would be proposed for the site in the future. With respect to water quality, no structural systems are currently in place to control the polhitants associated with the existing land uses of dry farming and gazing, such as organic matter, animal wastes, pesticides, and fertilizer. Based on the proximity to the lakes and the streambed, the potential hazards to runoff and water quality are considered moderate to high. The No Project alternative would thus continue the current runoff conditions at Otay Lakes and Salt Creek. Although the No Project alternative is considered environmentally preferable to the proposed project, it would not accomplish several of the goals and objectives of the proposed project. Finding: 1. The No Project alternative would not provide housing, which conflicts with the housing goals of the General Plan, which recommends that housing be provided for all income groups. 2. This alternative does not provide employment opportunities 3. This alternative provides little or no support for public transit, conflicting with the adopted General Plan transit goals. 4. Retention of the project site in its existing state as primarily agricultural fields would be inconsistent with the approved General Plan and existing EastLake 103 General Development Plan land use designations for the site. In addition, key subregional traffic routes established in the Circulation Element would not be implemented. 5. This alternative does not provide geenbelt connections. nor would it provide uses complimentary to the Ol,vmpic Training Center. 6. Retention of the site in its current vacant condition would not implement the goals of the General Plan and would require reevaluation of the existing GDP. The project proposes to provide regional-serving public facilities designated in the community plan, including Circulation Element roads, schools, parks, open space, water conveyance facilities, and other infrastructure. These facilities would be needed to support surrounding developments whether the project is implemented or not. The No Project alternative would require that these facilities be provided without the benefit of the dedications and financial participation from private development, which may delay or preclude facilities from being provided. The reduction in dwelling units will result in a loss of contributions into the PFFP from the dwelling units/structures that would otherwise have made payments upon issuance of building permits. The loss of units under the No Project alternative would result in a shortfall of contributions into the PFFP and potentially lead to insufficient funding for the remaining public facilities currently identified in the PFFP for construction in this area. 7. The City and County would receive much lower long-term revenues in the form of property and sales tax, resulting from the nondevelopment of residential. implementation of the No Project Alternative would achieve very few of the objectives established for the project. Although this Alternative would at least temporarily preserve the open space and other natural features on the project site, it would amount to a failure to attempt to plan the site for eventual development, despite the planned cogunity designation contemplated by the General Plan and GDP. The No Project Alternative is inconsistent with the City' s objectives seeking to plan the project area in a comprehensive manner in a way that deals with the logical extension of public services and utilities. plans for parks and open space to serve residents, completes the City's circulation and geenbelt systena within the City, and creates densities sufficient to pay for all required services and infrastructure. The Alternative also falls to meet objectives favoring an accommodation of future projected population in an area reasonably close to future job-growth areas within the City, and favoring the construction of affordable housing consistent with the City' s goals. 104 For these reasons, the City Council concludes that the No Project Alternative is not feasible. (See Cio, of Del Mar, supra, 133 Cal.App.3d at 417: Sequoyah Hills. supra, 23 Cal.App.4th at 715.) B. DEVELOPMENT CONSISTENT WITH THE EXISTING EASTLAKE HI GDP An alternative land use concept to the proposed project would be to implement the existing GDP and not proceed with the proposed amendments and corresponding SPA Plan for the Woods and Vistas. Under this scenario, land uses adopted for the Woods and Vistas would remain as shown in the adopted EastLake 1]/GDP (see SEIR Figure 3-1 and Table 3-1). Under this scenario, the proposed amendments to the City of Chula Vista's General Plan would not be implemented. Potential impacts associated with this alternative would not be substantially different from those of the proposed project because the adopted and proposed GDP plans are generally similar with respect to land use designations and hence share comparable development requirements and impacts. As a result, the alternative is not considered environmentally preferable to the proposed project. Furthermore, this alternative would not accomplish some of the replanning goals and objectives for the Woods and the Vistas associated with the proposed GDP. Finding: 1. The resulting site design under this alternative would not implement the land use concepts/objectives associated with the proposed project. Overall implementation of the existing GDP would create a community with less residential acreage and dwelling units and more nonresidential acreage as compared to the proposed GDP. Under the proposed GDP there would, for example, be a modest increase in buildout dwelling units (2,061 as compared to 1,767) which helps meet the re~on's housing demand. In addition, this alternative does provide as wide of an array of housing densities in both single- and multi-family options. 2. In addition, the location of the elementary school shown in the existing plan would provide less inte~ation of the school/residential uses from a land use planning perspective and is not as easily accessed as the site in the proposed GDP. 3. Also, this alternative would not implement the improvements to the internal circulation pattern, including a Class 1II collector road which would be added to the circulation element along the eastern portion of the Vistas neighborhood under the proposed GDP Amendment. 4. This alternative does not provide for as many community amenities as the proposed GDP, including a fire station site and community purposes facility site. 105 In addition this alternative does not include provisions for an Otay tarplant preserve and a mitigation area in the Salt Creek corridor to protect sensitive biolo~cal resources. Implementation of this Alternative would not achieve as many of the objectives established for the project. Compared to the proposed project, the Alternative is less consistent with the City~s housing and transportation/traffic circulation objectives and does not provide as much protection for Otay Tarplant and the habitats associated with Salt Creek. For these reasons, the City Council concludes that the Development Consistent with the Existing EastLake III GDP Alternative is not feasible. (See City of Del Mar, supra, 133 Cal.App.3d at 417; Sequoyah Hills, supra, 23 Cal. App.4th at 715.) STATEMENT OF OVERRIDING CONSIDERATIONS FOR THE PROPOSF. D EASTLAKE WOODS AND VISTAS REPLANNING PROGRAM SEIR The project would have significant, unavoidable impacts on the following areas, described in detail in these Findings of Fact: Transportation/Traffic (cumulative). · Landform Alteration/Visual Quality (cumulative) · Air Quality (direct project, construction-related, and cumulative). The City has adopted all feasible mitigation measures with respect to these impacts. Although in these mitigation measures may substantially lessen these significant impacts, adoption of the measures will not, in some cases, fully avoid the impacts. Cumulative impacts to traffic and landform alteration remain significant after mitigation, as do project and cumulative impacts to air quality. Moreover, the City has examined a reasonable range of alternatives to the project. Based on this examination, the City has determined that none of these alternatives both (1) meet project objectives and (2) are enviromnentally preferable to the finally approved project. As a result, to approve the project the City must adopt a "statement of overriding considerations" pursuant to CEQA Guidelines sections 15043 and 15093. This statement allows a lead agency to cite a project's economic, social or other benefits as a I06 justification for choosing to allow the occurrence of specified si~_~d~cant environmental effects that have not been avoided: The statement explains why, in the agency's judgment, the project's benefits outweigh the unavoidable si~ificant effects. Where another substantive law (e.g., the California Clean Air Act, the Federal Clean Air Act, or the California or Federal Endangered Species Acts) prohibits the lead agency from taking certain actions with environmental impacts, a statement of overriding considerations does not relieve the lead agency from such prohibitions. Rather, the decisionmaker has recommended mitigation measures based on the analysis contained in the final SEIR, recognizing that other resource agencies have the ability to impose more stringent standards or measures. CEQA does not require lead agencies to analyze "beneficial impacts" in an EIR. Rather, EIRs are to focus on potential "significant effects on the environment," defined to be "adverse." [Pub. Resources Code section 21068] The Legislature amended the definition to focus on "adverse" impacts after the California Supreme Court had held that beneficial impacts must also be addressed. Nevertheless, decisionmakers benefit from information about project benefits. These benefits can be cited, if necessary, in a statement of overriding considerations. [CEQA Guidelines section 15093.] Any one of the reasons for approval cited below is sufficient to justify approval of the Project. Thus, even if a Court were to conclude that not every reason is supported by substantial evidence, the City Council would stand by its determination that each individual reason is sufficient. The substantial evidence supporting the various benefits can be found in the preceding findings, which are incorporated by reference into this Section, and in the documents found in the Record of Proceedings, as defined in Section IV. The City finds that the project would have the following substantial social. environmental, and economic benefits: 1. The project would place approximately 138 acres in open space for the benefit of residents, the public, and wildlife, including the Otay tarplant preserve and Salt Creek mitigation area. 2. The overall project area from a cumulative standpoint currently exceeds federal and state air quality standards for a number of emissions factors, including ozone and carbon monoxide. A substantial majority of these emissions are attributable to motor vehicles. In order to comply with the federal and California Clean Air Acts, the San Diego region must reduce these sources. The project is desigmed to reduce the adverse impact to air quality and automobile congestion by encouraging use of aitemative modes of transportation such as biking and walking and the use of transit. 107 Trolley service is also planned for the Eastern Territories to provide additional transit opportunities. 3. The project will provide for significant community-wide pubhc facilities. As the plan is implemented, it will be responsible for constructing public facilities and infrastructure to serve the project and incidentally the subregion. These facilities include: a) Improvements to regional backbone circulation sysmm; b ) Schools serving the subregion including the on-site elementary and middle schools; c) A public park and gTeenbelt and community trails; d) A fire station and a community purpose facility; and Water line and sewer infrastructure improvements. 4. The project is generally consistent with and implements the land use designations of the existing General Plan and General Development Plan, ' provides a mix of land uses that provides housing opportunities, recreational opportunities, and public facilities in the Eastern Territories of the City of Chula Vista. In addition to helping reduce the projected countywide housing shorffall, the project also proposes a portion of the dwelling units for affordable housing. A minimum of 10 percent of the project's total dwelling units will be designated for low and moderate income households, with one-half of these units (5 percent of the total project) designated to low income and the remaining five percent to moderate income households. The project therefore provides the opportunity to complete the comprehensive planning process initiated for the overall EastLake planned community in 1982. 5. The project will help meet a projected long-term regional need for housing by providing a wide variety of housing t.vpes and prices. SANDAG housing capacity studies indicate a shortage of housing will occur in the project area within the next 20 years. In recent years, the cost of housing has risen disproportionately to the cost of other uses in the project area (e.g., commercial, industrial), reflecting a shorffall in residentially zoned land. The project will help reduce the cost of housing by designating an adequate supply of suitable land for residential development. The proposed range of residential densities within EastLake Woods and Vistas 108 will result in housing types and prices that will promote socioeconomic diversity, which the City finds both important and desirable. 6. The fiscal impact analysis conducted for the EastLake Woods and Vistas Replanning Process has concluded that, at buildout, the project will have a net positive impact on the City of Chula Vista. Based on fiscal analyses prepared by CIC Research (2000) for EastLake ffI, the project is expected to have a positive net annual fiscal impact on the City. Anticipated revenues from EastLake gl project range from $324,000 in the first year of development to $3,933,000 at full buildout of the project, with the net annual fiscal impact being positive from year 1 ($37,000) to buildout ($1,837,000). 7. The project would generate new temporary construction-related jobs that would enhance the economic base of the re,on. 8. Commercial tourist and conunercial retail uses will serve the needs of OTC visitors and help ensure the long-term success of the OTC as a world-class athletic training facility. 9. The project would provide a variety of housing types, ran~ng from estates with lake views to multi-family units near the Village Center and OTC, that would help achieve the City's goals to provide housing opportunities for various income levels. For these reasons on balance, the City Council finds there are economic, social, and other considerations resulting from the project that serve to override and outweigh the project' s unavoidable si~-ntificant environmental effects and, thus, the adverse unavoidable effects are considered acceptable. I09 EXHIBIT B EASTLAKE III WOODS AND VISTAS REPLANNING PROGRAM MITIGATION MONITORING REPORTING PROGRAM Introduction This mitigation monitoring reporting proyam (MMRP) was prepared for the City of Chula Vista for the EastLake I]ZI Woods and Vistas Replanning Proyam to comply with Assembly Bill 3180, which requires public agencies to adopt such prograrns to ensure effective implementation of mitigation measures. This monitoring program is dynamic in that it will undergo changes as additional mitigation measures are identified and additional conditions of approval are placed on the project throughout the project approval process. This monitoring proyam will serve a dual purpose of verifying completion of the mitigation measures for the proposed project and generating information on the effectiveness of the mitigation measures to guide future decisions. The program includes the following: · Monitoring team qualifications · Specific monitoring activities · Reporting system The EastLake UI Replanning ProHam includes EastLake Woods, EastLake Vistas, and the Panhandle site, all located within the EastLake l]] General Development Plan (GDP) area. Development of the Woods and Vistas would involve the construction of a total of 27061 dwelling units. The eastern portion of the Woods is planned for single-family residential use. including custom low density estate homes in the area closest to the Upper Otay Reservoir. West of Hunte Parkway, low-medium density detached homes are proposed in the area known as "Woods West." Low density estate homes are also planned for the eastern portion of the Vistas. while more traditional single-family homes in low- to low-medium densities are planned for the western portion. Low-medium density as well as medium, medium-nigh, and high density housing, with densities up to 20 dwelling units per acre, are planned for the southern portion of the Vistas adjacent to the proposed Village Center and existing Olympic Training Center. Business Center I] is a 102.6-acre parcel located to the west of the Woods on Otay Lakes Road. It is currently part of the adopted GDP for EastLake III but has an approved tentative map as part of an extension of the EastLake Business Center further to the west. It is included in the proposed EastLake IIZI GDP to be de-annexed into the EastLake 11 GDP. The Village Center would include both Commercial Tourist and Commercial Retail uses such as a hotel, restaurants, and shops designed to sen'e the EastLake community, with particular emphasis on serving the needs of Olympic Training Center visitors, staff, and athletes. EastLake HI also proposes several public facilities, including schools, park and recreation areas, and a fire station site. Open space is designated around the perimeter of both neighborhoods, some of which would be incorporated into the EastLake Community Trail and/or the City of Chula Vista's Greenbelt Trail. The project also includes designating the 45-acre Panhandle site for Public/Quasi-Public uses, with a secondary use of Low Density Residential. With a Low Density Residential use the Panhandle site could accommodate as many as 90 single-family dwelling units. Future plans and applications to develop the Panhandle site will be subject to a more comprehensive review under the California Environmental Quality Act and will be subject to further, more specific mitigation measures as necessary. The proposed amendments to the EastLake 1II GDP, Chula Vista General Plan, and the SPA Plan for the Woods and Vistas are described in the Subsequent Environmental impact Report (SEIR) text. The SEIR, incorporated herein as referenced, focused on issues determined to be potentially si~-mificant by the City of Chula Vista. The issues addressed in the SEIR include land use, transportation/traffic, biological resources, hydrology/drainage, landform alteration/visual quality, geology/geologic hazards, noise. air quality, cultural/paleontological resources, and public facilities. The environmental analysis concluded that for all of the environmental issues discussed, some of the significant and potentially significant impacts could be avoided or reduced through implementation of recommended mitigation measures. Potentially significant cumulative impacts requiring mitigation were identified for transportation/traffic circulation, hydrology/drainage, landform alteration/visual quality, noise, air quality, cultural/paleontolo~cal resources, and public facilities. Assembly Bill 3180 requires monitoring of only those impacts identified as sig~tificant or potentially sigrdficant. The monitoring program for the EastLake llI Replanning Program therefore addresses the impacts associated with only the issue areas identified above. Mitigation Monitorin_,2 Team A monitoring team should be identified once the mitigation measures have been adopted as conditions of approval by the Chula Vista City Council. Managing the team would be the responsibility of the Mitigation Monitor (MM). The monitoring activities would be accomplished by the Environmental Monitors (EMs), Environmental Specialists (lESs), and the MM. While specific qualifications should be determined by the City of Chula Vista, the monitoring team should possess the following capabilities: · Interpersonal, decision-making, and management skills with demonstrated experience in working under trying field circumstances; · Knowledge of and appreciation for the general environmental attributes and special features found in the project area: · Knowledge of the types of environmental impacts associated with construction of cost-effective mitigation options; and · Excellent communication skills. The responsibilities of the MM throughout the monitoring effort include the following: · Implement and manage the monitoring proHam; · Provide quality control for the site-development monitoring: · Administrate and prepare dally logs, status reports, compliance reports, and the final construction monitoring; · Act as liaison between the City of Chula Vista, the EastLake Company (the project applicant), and the applicant's contractors; · Monitor on-site, day-to-day construction activities, including the direction of EMs and ESs in the understanding of all permit conditions, site-specific project requirements, construction schedules, and environmental quality control effort; · Ensure contractor knowledge of and compliance with all appropriate permit conditions: · Review all construction impact mitigation and, if need be, modify existing mitigation or proposed additional mitigation; · Have the authority to require correction of observed activities that violate project environmental conditions or that represent unsafe or dangerous conditions; and · Maintain prompt and regular communication with the on-site EMs and ESs and personnel responsible for contractor performance and permit compliance. The primary role of the Environmental Monitors is to serve as an extension of the MM in performing the quality control functions at the construction sites. Their responsibilities and functions are to: 3 · Maintain a working 'knowledge of the EastLake III permit conditions, contract documents, construction schedules and progress, and any special mitigation requirements for his or her assigned construction area: · Assist the MM and EastLake l]I construction contractors in coordinating with City of Chula Vista compliance activities; · Observe consu'uction activities for compliance with the City of Chula Vista permit conditions; and · Provide frequent verbal briefings to the MM and construction personnel, and assist the MM as necessary in preparing status reports. The primary role of the Environmental Specialists is to provide expertise when environmentally sensitive issues occur throughout the development phases of project implementation and to provide direction for mitigation. Program Procedural Guidelines Prior to any construction activities, meetings should take place between all the parties involved to initiate the monitoring program and establish the responsibility and authority of the participants. Mitigation measures that need to be defined in greater detail will be addressed prior to any project plan approvals in follow-up meetings designed to discuss specific monitoring effects. An effective reporting system must be established prior to any monitoring efforts. All parties involved must have a clear understanding of the mitigation measures as adopted and these mitigations must be distributed to the participants of the monitoring effort. Those that would have a complete list of all the mitigation measures adopted by the City of Chula Vista would include the City of Chula Vista, the project applicant, the MM, and the construction crew supervisor. The MM would distribute to each Environmental Specialist and Environmental Monitor a specific list of mitigation measures that pertain to his or her monitoring tasks and the appropriate time flame that these mitigations are anticipated to be implemented. In addition to the list of mitigation measures, the monitors will have mitigation monitoring report (MMR) forms, with each mitigation measure wfiuen out on the top of the form. Below the stated mitigation measure, the form will have a series of questions addressing the effectiveness of the mitigation measure. The monitors shall complete the MMR and file it with the MM following the monitoring activity. The MM will then include the conclusions of the MMR into an interim and final comprehensive construction report to be submitted to the City of Chula Vista. This report will describe the major accomplishments of the monitoring pro~am, summarize problems encountered in achieving the goals of the program, evaluate solutions developed to overcome 4 problems, and provide a list of recommendations for future monitoring programs. In addition, and if appropriate, each EM or ES will be required to fill out and submit a daily log report to the MM. The dally log report will be used to record and account for the monitoring activities of the monitor. Weekly an~or monthly status reports, as determined appropriate, will be generated from the daily logs and compliance reports and will include supplemental material (i.e., memoranda, telephone logs, and letters). This type of feedback is essential for the City of Chula Vista to confirm the implementation and effectiveness of the mitigation measures imposed on the project. Actions in Case of Noncompliance There are generally three separate categories of noncompliance associated with the adopted conditions of approval: · Noncompliance requiring an immediate halt to a specific task or piece of equipment; · Infraction that warrants an immediate corrective action but does not result in work or task delay; and · Infraction that does not warrant immediate corrective action and results in no work or task delay. In each case, the MM would notify the EastLake I]I contractor and the City of Chula Vista of the noncompliance, and an MMR would be filed with the MM on a daily basis. There are a number of options the City of Chula Vista may use to enforce this proyam should noncompliance continue. Some methods commonly used by other lead agencies include "stop work" orders, fines and penalties (civil), restitution, permit revocations, citations, and injunctions. It is essential that all parties involved in the program understand the authority and responsibility of the on-site monitors. Decisions regarding actions in case of noncompliance are the responsibility of the City of Chula Vista. SU1VIMARY OF PROJECT IMPACTS AND MITIGATION MEASURES The following table summarizes the potentially significant project impacts and lists the associated mitigation measures and the monitoring efforts necessary to ensure that the measures are properly implemented. All the mitigation measures identified in the EIR are recommended as conditions of project approval and are stated herein in language appropriate for such conditions. In addition, once the EastLake ffI Replanning Program has been approved, and during various stages of implementation, the designated monitors, the City of Chula Vista, and the applicant will further refine the mitigation measures.
