The proposed SPA Plan is a document that refines and implements the land use plans, goals, and objectives of the Otay Ranch General Development Plan (GDP) for the development of Village 8 West. CEQA Statute Section 21002 requires that an EIR identify the significant effects of a project on the environment and provide measures or alternatives that can mitigate or avoid these effects. This Draft EIR evaluates the environmental effects associated with development of the project and discusses the manner in which the project’s significant effects can be reduced or avoided through the implementation of mitigation measures or feasible alternatives to the proposed project. In accordance with Section 15130 of the CEQA Guidelines, this EIR also includes an examination of the effects of cumulative development. The 2013 General Plan Amendment/General Development Plan Amendment SEIR (SEIR 09-01), 2005 General Plan Update Final Program EIR (EIR 05-01), and the 1993 Otay Ranch GDP Program Final EIR (EIR 90-01) are incorporated by reference in accordance with CEQA Guidelines Section 15168(d). This Draft EIR addresses environmental issues associated with the project that were not evaluated in the previously certified EIRs and updates information in these EIRs pertaining to the project area. This summary provides a brief synopsis of: 1) the proposed project, 2) results of the environmental analysis contained within this environmental document, 3) alternatives to the proposed project that were considered, and 4) major areas of controversy and issues to be resolved by decision-makers. This summary does not contain the extensive background and analysis found throughout the individual chapters within the EIR. Therefore, the reader should review the entire document to fully understand the project and its environmental consequences. 1.1 Project Location and Setting The project consists of approximately 300 acres of land in Otay Ranch known as Village 8 West, located entirely within the city of Chula Vista, California, near the southeasterly edge of the city limits. Chula Vista is located in San Diego County, approximately 13 miles southeast of the downtown area of the city of San Diego, and approximately 7 miles north of the U.S./Mexico international border. Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-2 City of Chula Vista November 2013 The project site is currently undeveloped. La Media Road currently terminates at the northerly boundary of Village 8 West, and a portion of Magdalena Avenue runs along the northeast boundary of the site. Rock Mountain is located to the west and southwest and the Otay River Valley is south of the site. A reservoir facility owned and operated by the City of San Diego is located in approximately the center of the project site. This facility is not a part of the proposed Village 8 West SPA Plan. 1.2 Project Background Otay Ranch is a partially developed master-planned community that proposes a broad range of residential, commercial, retail, and industrial development interwoven with civic and community uses, such as libraries, parks, and schools. The community is 23,000 acres in size, and includes an open space preserve system consisting of approximately 11,375 acres. Village 8 West is one of the designated fourteen villages within the Otay Ranch General Development Plan (GDP) area. The GDP was recently amended in 2013. The GDP establishes land plans, design guidelines, objectives, policies, and implementation measures that apply to all portions of Otay Ranch while supporting a balance of housing, shops, workplaces, schools, parks, civic facilities, and open spaces. The majority of development is intended to be clustered in villages, with conveniently located features and well-defined edges such as the Chula Vista greenbelt, open spaces, and wildlife corridors. Under the implementation program for the Otay Ranch GDP, review and City Council approval of SPA plans is required before final development entitlements can be considered. The GDP defines Village 8 West as an urban village. The GDP states, “Urban villages are adjacent to existing urban development and are planned for transit oriented development with higher densities and mixed uses in the village cores.” According to the GDP, Village 8 West is to provide single-family and multi-family residential units, a Town Center containing commercial uses, parks, a community purpose facility site, schools, affordable housing and a transit stop. The most intense development would be concentrated near the Town Center, with building heights and density gradually decreasing with distance from the center. 1.3 Project Description The project includes the SPA Plan and TM for Village 8 West, including associated off-site improvements, consistent with the Otay Ranch GDP. The development proposed by the Otay Land Company (OLC) pursuant to the Village 8 West SPA Plan is referred to as the “project,” and is the focus of this EIR. The Village 8 West SPA Plan is incorporated by reference and is available for review at the offices of the City of Chula Vista, Development Services Department, located at 276 Fourth Avenue, Chula Vista, California 91910. The components of the project description are summarized briefly below and detailed in Chapter 3. 1.3.1 Development Concept Village 8 West has been planned in transects to provide organization for development that focuses activity within the Town Center, transitioning into residential opportunities and rural open space at the edges. Uses include an elementary school, a middle school, a variety of parks, various open space areas, multi-family and single-family residential units, and mixed-use areas. The proposed land uses and proposed maximum residential unit yield for Village 8 West are provided below in Table 1-1.

The corridor would be 30 feet wide, including a 20-foot sewer corridor to connect to existing sewer facilities, and a 10-foot storm drain corridor to direct drainage to Otay River. A 12-foot paved utility access road would be included within the 30-foot utility corridor. This utility access road would provide access for the off- site utilities and would serve as a trail connection to the Otay Valley Regional Park trail system. The project would also require 4.6 acres of off-site grading on the City of San Diego reservoir site in the middle of Village 8 West. 1.3.3 Mobility The Village 8 West circulation system would provide a system of roadway and trail corridors to support both vehicular and non-vehicular modes of transportation. This system includes the extension of existing and planned roads, trails, and transit from adjacent villages as well as internal systems to serve the project site. Streets in the community are designed as “complete” streets, considering all modes of transportation by providing vehicular travel lanes, bike lanes or bike routes, sidewalks, and transit lanes where appropriate. 1.3.4 Infrastructure The SPA Plan includes plans to provide adequate infrastructure to the proposed development, including water distribution, recycled water distribution, sewer service, and storm water collection. 1.3.5 Tentative Map The TM for Village 8 West details how the utilization plan would be implemented. The map includes the various land uses, proposed grading, and street layout. In addition, a TM depicts proposed utilities, easements and conceptual trail design. Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-4 City of Chula Vista November 2013 1.3.6 Project Objectives The SPA Plan identifies project objectives that would implement the aforementioned GDP vision for Village 8 as indicated below: 1. Create a recognizable “place” that is unique, attractive, and full of cultural and social diversity. 2. Develop distinctive design standards and invest in design excellence to create inspiring and memorable places; emphasize the appearance and qualities of the public realm; create streetscapes, pathways, and public spaces of beauty, interest, and functional benefit to pedestrians. 3. Encourage development patterns that promote orderly growth, prevent urban sprawl, and promote effective resource management. 4. Protect and enhance the natural environment and increase the quality of life. Design neighborhoods with compact and multi-dimensional land use patterns that ensure a mix of uses and joint optimization of transportation modes to minimize the impact of cars, promote walking and bicycling, and provide access to employment, education, recreation, entertainment, shopping, and services. 5. Create an appropriately scaled and economically healthy Town Center. Include a wide range of commercial, residential, cultural, civic, recreational uses, and businesses that serve the daily needs of nearby residents. 6. Establish a pedestrian and transit-oriented village with an intense, vibrant Town Center to reduce reliance on the automobile and promote walking and the use of bicycles, buses, and regional transit. 7. Encourage community development in mixed use and compact pedestrian oriented forms to accommodate all income levels and lifestyles. 8. Foster a compact form facilitated by “form-based planning,” resulting in efficient infrastructure investments and advanced opportunities to provide socially diverse housing. 9. Retain and recruit a skilled and motivated workforce to ensure economic stability into the future by providing attainable housing opportunities. Promote jobs that match the skills of existing and future residents through provision of housing opportunities and choices and by providing an opportunity for the City to attract a university or related uses by dedication of land for such purposes. 10. Promote synergistic uses and graceful transitions within the SPA and between the SPA and neighborhoods of adjacent SPAs to balance activities, services, and facilities. Integrate Village 8 West with existing Otay Ranch development, including connectivity to the Greenbelt. 11. Implement the goals, objectives and policies of the Chula Vista General Plan, the Otay Ranch General Development Plan, the Chula Vista Greenbelt Master Plan, and the Otay Valley Regional Park Concept Plan. 12. Encourage the interactivity of a wide range of people, promote community diversity, and enrich the human experience by providing a broad variety of public spaces and housing types and styles that appeal to all ages, incomes, and lifestyles. 13. Establish a plan that is fiscally responsible and viable with consideration of existing and anticipated economic conditions. Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-5 City of Chula Vista November 2013 1.3.7 Discretionary Actions The project is a “discretionary project,” which is defined in Section 15357 of the CEQA Guidelines as “a project that requires the exercise of judgment or deliberation when the public agency or body decides to approve or disapprove a particular activity.” The following discretionary actions are associated with the project and would be considered by the Chula Vista Planning Commission and City Council: ■ Adoption of the Village 8 West SPA Plan and associated documents including but not limited to:  Village 8 West SPA Plan  Air Quality Improvement Plan  Agricultural Plan  Non-Renewable Energy Conservation Plan  Preserve Edge Plan  Fire Protection Plan  Affordable Housing Plan  Water Conservation Plan  Parks, Recreation, Open Space Master Plan  Emergency Disaster Plan  Public Facility Finance Plan ■ Approval of a tentative map to establish the location of development and open space lots and identify the infrastructure requirements for Village 8 West ■ Approval of a development agreement amendment including conditions of approval for development within the Village 8 West SPA Plan area ■ Certification of a Final EIR and adoption of a mitigation monitoring and reporting program 1.4 Areas of Controversy The Notice of Preparation (NOP) was distributed June 25, 2010 for a 30-day public review and comment period and a public scoping meeting was held in July 2010. Public comments were received on the NOP and at the scoping meeting related to several environmental issues. The NOP and comment letters are included in this EIR as Appendix A. Controversy associated with the project primarily concerns the issues of public services, landform alteration, hazards from Brown Field, wildland fire, biological resources, and traffic. These issues are analyzed in the EIR. 1.5 Issues to be Resolved by the City Council The issues to be resolved by the decision-making body are whether to adopt the proposed project and how to mitigate significant effects created by its implementation. The City will decide if benefits of the project outweigh any significant unmitigable impacts associated with scenic resources and visual character (degradation of rolling hills), air quality (consistency with existing plans, increased criteria pollutants), noise (short-term increase in traffic noise), cultural resources (cumulative disturbance of archaeological resources and human remains), potential effects of climate change (exacerbate air quality problems), agricultural resources (conversion of agricultural resources), and public utilities (water, wastewater, energy, and cumulative recycled water demand). Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-6 City of Chula Vista November 2013 The City will also decide if the significant impacts associated with the environmental issues of land use (compatibility with existing water lines), aesthetics (lighting and glare, landform alteration, scenic resources); transportation and traffic (level of service standards, congestion management, air traffic patterns), air quality (sensitive receptors), noise (excessive noise levels), biological resources (sensitive plant and wildlife species, riparian habitat and other sensitive natural communities, federally protected wetlands, local policies and ordinances), cultural resources (paleontological resources, direct impacts to archaeological resources and human remains), geology and soils (exposure to seismic related hazards, soil erosion or topsoil loss, soil stability, expan sive soils), hydrology and water quality (storm water pollution, public services (fire and emergency medical services, police services, schools, libraries, parks and recreation), agricultural resources (land use zoning conflicts), hazards and hazardous materials (accidental release of hazardous materials, hazards to schools, airport hazards, consistency with hazard policies, historic use of pesticides), and public utilities (direct demand for recycled water) have been fully mitigated below a level of significance. Lastly, the City would determine whether any alternative might meet the key objectives of the project while reducing its environmental impact. 1.6 Project Alternatives Section 15126.6 of the CEQA Guidelines requires the discussion of “a range of reasonable alternatives to the project, or to the location of the project, which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project” and the evaluation of the comparative merits of the alternatives. The alternatives discussion is intended to “focus on alternatives to the project or its location which are capable of avoiding or substantially lessening any significant effects of the project,” even if these alternatives would impede to some degree the attainment of the project objectives. The EIR addresses the No Project (No Build) Alternative and two reduced project alternatives: Reduced Project Alternative #1 – 1,167 Dwelling Units, and Reduced Project Alternative #2 – 672 Dwelling Units. Alternatives to the project are evaluated in full in Chapter 10 of this document. 1.6.1 No Project–No Build Alternative The No Project (No Build) Alternative assumes that no SPA Plan would be developed for Village 8 West and that the project area would remain unchanged. Accordingly, the site characteristics of this alternative would be equivalent to the existing conditions for each category analyzed in this EIR. 1.6.2 Reduced Project Alternative #1 – 1,167 Dwelling Units Reduced Project Alternative #1 would include the development of 1,167 residential units, compared to 2,050 units under the proposed Village 8 West SPA Plan and TM. This alternative is intended to provide a more suburban approach to development in the SPA Plan area, which reduces residential development by almost 50 percent. Under the Reduced Project Alternative #1, no residential units would be developed in Planning Areas B, C, H-1, or L. Multi-family residential units would still be developed in Planning Areas F and J, at reduced densities compared to the project. Commercial development in the Town Center would also be reduced to 170,000 square feet, compared to 300,000 square feet under the proposed project. Additionally, the Neighborhood Park proposed for the project would be eliminated under this alternative. The park area (Planning Area T) would be designated for single-family residential development to further reduce density in the Neighborhood General Zone. Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-7 City of Chula Vista November 2013 1.6.3 Reduced Project Alternative #2 – 672 Dwelling Units Reduced Project Alternative #2 would include the development of 672 residential units, compared to 2,050 units under the proposed project. This lower density alternative is intended to provide more open space and eliminate mixed-use development. The greatest reduction in development would occur in the Town Center. Under this alternative, no mixed-use development is proposed and no residential development would occur in the Town Center. Residential densities would also be reduced in the Neighborhood Edge, Neighborhood General, and Neighborhood Central Zones. Commercial development in the Town Center would also be reduced to 104,000 square feet, compared to 300,000 square feet under the project. Additionally, the Neighborhood Park proposed for the project would be eliminated under this alternative. The park area (Planning Area T) would be designated for single-family residential development to further reduce density in the Neighborhood General Zone. The development footprint would be reduced until this alternative. Portions of Planning Areas N, P, and V of the proposed project would be replaced with an open space designation. This alternative would include 40.4 acres of open space, compared to 23.5 acres under the project. This additional open space area would provide additional transition from developed areas to the Multiple Species Conservation Program Preserve, but would not be incorporated into the Preserve. 1.6.4 Environmentally Superior Alternative The No Project (No Build) Alternative would be the environmentally superior alternative, as it would entirely avoid the project’s significant and unavoidable impacts associated with aesthetics (direct and cumulative), air quality (direct and cumulative), noise (short-term direct), archaeological resources and human remains (cumulative), potential effects of climate change (direct and cumulative), agricultural resources (direct and cumulative), water supply (direct and cumulative), wastewater treatment capacity (cumulative), recycled water (cumulative), and energy (direct and cumulative). However, as the No Project (No Build) Alternative is determined to be environmentally superior, another environmentally superior alternative must be identified among the remaining alternatives. The Reduced Project Alternative #2 is identified as the environmentally superior alternative as it would reduce traffic (direct and cumulative), air quality (direct and cumulative), noise (direct and cumulative), biological resources (direct), public services (direct), water quality (direct), and public utilities (direct and cumulative) impacts. Mitigation measures 5.3-7 through 5.3-16 and 5.3-18 through 5.3-20 identified for potential traffic impacts would not be required under this alternative and mitigation measure 5.5-3 would not be required for excessive noise impacts to residences in Planning Areas B, C, F, G, H1, H2, J, and L because no residences are proposed in these areas. However, as with the Reduced Project Alternative #1, this alternative would not avoid any of the project’s significant and unavoidable impacts associated with aesthetics (cumulative), air quality (direct and cumulative), noise (short-term direct), archaeological resources and human remains (cumulative), potential effects of climate change (direct and cumulative), agricultural resources (direct and cumulative), water supply (direct and cumulative), wastewater treatment capacity (cumulative), recycled water (cumulative), and energy (direct and cumulative). This alternative would reduce significant VOC emissions by approximately 57 percent and energy use by approximately 65 percent.

A significant land use compatibility impact would occur if the on-site City of San Diego water lines would not be relocated before development of Village 8 West. 5.1-1 Waterline Agreement. Prior to approval of the first final map, the applicant shall provide evidence, satisfactory to the City Engineer, that the: i. Applicant has entered into an agreement with the City of San Diego to relocate the City of San Diego waterlines within Village 8 West to a location approved by both the City of San Diego and the City of Chula Vista. ii. City of San Diego has abandoned any water main easements not needed as a consequence of the relocation of the City of San Diego waterlines within Village 8 West. 5.1-2 Waterline Relocation. Prior to issuance of the first grading permit within Village 8 West, the applicant shall relocate the City of San Diego waterlines to the satisfaction of the City of San Diego and the City of Chula Vista. Less than significant. Would the project conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, local coastal program, or zoning ordinance), adopted for the purpose of avoiding or mitigating an environmental effect? No significant impacts related to the conflicts with land use plans, policies, and regulations have been identified for implementation of the SPA Plan and TM for Village 8 West. No mitigation required. Less than significant. Would the project conflict with any applicable habitat conservation plan or natural community habitat conservation plan? No significant impacts related to Habitat Conservation Plans or Natural Community Conservation Plans have been identified for implementation of the SPA Plan and TM for Village 8 West, other than significant impacts identified in Section 5.6 Biological Resources. Implementation of the mitigation measures identified in this section would reduce all potential land use impacts to a less than significant level. No additional mitigation measures are required other than those listed in Section 5.6 Biological Resources. Less than significant.

No significant impacts to scenic vistas have been identified for the project. No mitigation required. Less than significant. Would the project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State Scenic highway? The project would alter a portion of the east-facing slope of Rock Mountain. 5.2-1 Landscape Master Plan. Prior to issuance of the first final map for Village 8 West, the applicant shall prepare to the satisfaction of the Development Services Director (or their designee), a Landscape Master Plan. The Landscape Master Plan shall demonstrate compliance with GDP Policies pertaining to softening manufactured slopes, particularly on Rock Mountain and other visible manufactured slopes greater than 25 feet in height, through plant selection, placement, and density, etc. Less than significant. Would the project substantially degrade the existing visual character or quality of the site and its surroundings? The project would permanently alter the character of the project site from open, rolling topography to urban development. This impact would be significant. Mitigation measure 5.2-1 would also reduce impacts to visual character or quality. Significant. Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? New sources of nighttime lighting from parks, mixed-use residential, commercial, multi-family residential, and Community Purpose Facility uses may be incompatible with surrounding development and inconsistent with applicable regulations. Potential impacts associated with light cannot be determined until the location, size, and orientation of future buildings are established. These impacts would be potentially significant. 5.2-2 Lighting Plan and Photometric Analysis - Parks. Concurrent with the preparation of site-specific plan(s) for park sites, including the town center park, Planning Area A and Planning Area T and prior to issuance of a building permit for any park, the applicant shall prepare, or in the case of the City being the lead on the preparation of the site specific plan, the applicant shall fund the preparation of a lighting plan and photometric analysis. The plan shall be prepared to the satisfaction of the Development Services Director (or their designee) and evaluate the proposed height, location, and intensity of all exterior lighting for compliance with the City's performance standards for light, and glare (Chula Vista Municipal Code19.66.100). 5.2-3 Lighting Plan and Photometric Analysis – New Structures. Concurrent with design review and prior to the issuance of building permits for mixed-use residential, commercial, Community Purpose Facility and multi-family residential, the applicant shall prepare a lighting plan and photometric analysis. The plan shall be prepared to the satisfaction of the Development Services Director (or their Less than significant.

Prior to design review approval for any structure three stories and above, the applicant shall prepare to the satisfaction of the Development Services Director (or their designee), a shadow analysis demonstrating that adjacent shadow-sensitive uses are not permanently shadowed, and/or any other approved city- standard in place at the time the shadow analysis is performed. Would the project alter areas of sensitive landforms and grade steep slopes that may be visible from future development and roadways that negatively detract from the prevailing aesthetic character of the site or surrounding area? The project would not significantly impact steep slopes. However, grading on a portion of the east- facing slope of Rock Mountain would be a potentially significant. Mitigation measure 5.2-1 would also reduce impacts to landform alteration. Less than significant. Would the project be inconsistent with General Plan, GDP, or other objectives and policies regarding visual character, thereby resulting in a significant physical impact? The project would be consistent with all applicable visual character policies. No mitigation required. Less than significant. 5.3 Transportation/Traffic Would the project conflict with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non- motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways, and freeways, pedestrian and bicycle paths, and mass transit? The project would result in direct and cumulative impacts on roadways and intersections under the Existing Plus Project, Year 2015, Year 2020, Year 2025, and Year 2030 Scenarios. Based on the Intersection Lane Volume Analysis, a significant direct impact would occur to the I-805 southbound ramps at Main Street, and a cumulative impact would occur to the I-805 northbound ramps at Main Street. Impacts related to congestion management would be potentially significant. Growth Management Oversight Commission Compliance (Section 19.09 of the CVMC) 5.3-1 Olympic Parkway: Heritage Road to Oleander Avenue: Prior to the issuance of the building permit for the 2,463rd dwelling unit for development east of I-805 (commencing from April 4, 2011), the applicant may: i.

No significant impacts related to groundborne vibration have been identified for the project. No mitigation required. Less than significant. Would the project result in a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Existing Plus Project Scenario and Unmitigated Year 2025 Scenario. Five roadway segments would result in a significant noise impact under the Existing Plus Project scenario: Birch Road, La Media Road to SR-125; Birch Road, SR-125 to Eastlake Parkway; La Media Road, Olympic Parkway to Birch Road; La Media Road, Birch Road to Main Street; and Magdalena Avenue, Birch Road to Main Street. Traffic-related noise is reduced either by constructing noise barriers, lowering traffic speeds, or by reducing traffic. Implementation of the SPA Plan and TM would include the construction of new roadways that would provide new connections from the project area to the regional transportation system. These new connections would reduce long- term traffic on the roadways surrounding the project site by routing some cumulative traffic through Village 8 West instead of the surrounding roadways. Additionally, these connections would direct traffic generated by Village 8 West away from the existing off-site roadways and reduce associated traffic noise. The 2030 buildout traffic scenario includes future roads that are proposed as part of the development plans for other villages. However, if the equivalent dwelling unit assumption for the buildout study year (2030) is reached prior to implementation of these roadways being open to traffic, then mitigation measure 5.3-20 in Section 5.3, Transportation and Traffic, would be implemented to ensure that this circulation system would be implemented concurrently with Village 8 West. Short-term increases in noise levels would Mitigation measure 5.3-20 would ensure that the regional circulation system would be implemented concurrently with Village 8 West. No mitigation required. Significant (Short-term, Existing + Project Only)/Less than significant (Long- term). Less than significant.

Unmitigated Year 2025 Scenario. One roadway segment would result in a significant impact under the Year 2025 Scenario: La Media Road, Birch Road to Main Street. As described above under the Existing Plus Project Scenario, the buildout circulation network for Village 8 West would reduce long-term traffic noise. Mitigation measure 5.3-20 would ensure that the circulation network is implemented concurrently with development. Unmitigated and Mitigated Year 2030 Scenarios. In the Unmitigated and Mitigated Year 2030 (Buildout) scenarios, Village 8 West would not result in a significant traffic noise increase on any roadway. Would the project result in a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Construction of the project would have the potential to generative noise levels and that would significantly impact biological resources.

No significant impacts related to historical resources have been identified for implementation of SPA Plan and TM. No mitigation required. Less than significant. Would the project cause a substantial adverse change in the significance of an archaeological resource? Construction activities associated with the project could inadvertently result in significant impacts to presently unknown archaeological resources that may be uncovered during clearing and grading. It is not anticipated that construction would extend beyond the defined area of potential effect. However, a mitigation measure is include below, consistent with the recommendations of the cultural resources report (Appendix F1), to avoid a potentially significant impact that could occur if construction activities inadvertently extended in the proximity of site CA-SDI-12809. 5.7-1 Protective Fencing. Prior to the issuance of any land development permits for the SPA Plan and associated off-site facilities, including clearing, grubbing, and grading, the applicant shall install protective fencing (i.e., orange snow fence or similar) along the area of potential effect in the area of CA-SDI-12809 as directed by a qualified archaeologist. A qualified archaeologist shall monitor the site throughout the construction of the off-site facilities (including clearing, grubbing, grading, and installation) to ensure that unanticipated finds are handled in an appropriate and professional manner and that required fencing remains intact and project related construction activities do not extend beyond the approved limits of work. 5.7-2 Archaeological Monitor. Prior to issuance of land development permits, including clearing or grubbing and grading permits, the applicant shall provide written confirmation and incorporate into grading plans, to the satisfaction of the Development Services Director (or their designee), that a principal investigator as listed by the Secretary of the Interior (Code of Federal Regulations Title 36, Section 61) has been retained in an oversight capacity to ensure than an archeological monitor(s) will be present during all cutting of previously undisturbed soil. If these cutting activities would occur in more than one location, multiple monitors shall be provided to monitor these areas, as determined necessary by the principal investigator. Less than significant. Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-39 City of Chula Vista November 2013 Table 1-2 Summary of Significant Environmental Analysis Results (continued) Environmental Issue Result of Impact Analysis Mitigation Impact Level After Mitigation 5.7-3 Resource Discovery Procedure. During the initial grading of previously undisturbed soils within Village 8 West and the off-site improvement area, prehistoric and historic resources may be encountered. In the event that the monitor identifies a potentially significant site, the archaeological monitor shall secure the discovery site from further impacts by delineating the site with staking and flagging, and by diverting grading equipment away from the archaeological site. Following notification to the Development Services Director (or their designee), the archaeological monitor shall conduct investigations as necessary to determine if the discovery is significant under the criteria listed in CEQA and the environmental guidelines of the City of Chula Vista. If the discovery is determined to be not significant, grading operations may resume and the archaeological monitor shall summarize the findings in a letter report to the Development Services Director (or their designee) following the completion of mass grading activities. The letter report shall describe the results of the on-site archeological monitoring, each archaeological site observed, the scope of testing conducted, results of laboratory analysis (if applicable), and conclusions. The letter report shall be completed to the satisfaction of the Development Services Director (or their designee) prior to release of grading bonds. Any artifacts recovered during the evaluation shall be curated at a facility approved by the Development Services Director (or their designee). For those prehistoric/historic resources that are determined to be significant, the following measures shall be implemented: i. An alternate means of achieving mitigation shall be pursued. In general, these forms of mitigation include: 1) site avoidance by preservation of the site in a natural state in open space or in open space easements, 2) site avoidance by preservation through capping the site and placing landscaping on top of the fill, 3) data recovery through implementation of an excavation and analysis program, or 4) a combination of one or more of the above measures. Procedures for implementing the alternative forms of mitigation described herein are further detailed in the Mitigation Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-40 City of Chula Vista November 2013 Table 1-2 Summary of Significant Environmental Analysis Results (continued) Environmental Issue Result of Impact Analysis Mitigation Impact Level After Mitigation Monitoring and Reporting Program adopted as part of the 1993 Otay Ranch General Development Plan Program EIR (EIR 90-01). ii. For those sites for which avoidance and preservation is not feasible or appropriate, the applicant shall prepare a Data Recovery Plan. The plan shall, at a minimum, include the following: 1) a statement of why data recovery is appropriate as a mitigating measure, 2) a research plan that explicitly provides the research questions that can reasonably be expected to be addressed by excavation and analysis of the site, 3) a statement of the types and kinds of data that can reasonably be expected to exist at the site and how these data will be used to answer important research questions, 4) a step-by-step discussion of field and laboratory methods to be employed, and 5) provisions will be stated for curation and storage of the artifacts, notes, and photographs. In cases involving historic resources, archival research and historical documentation shall be used to augment field-testing programs. Grading operations within the affected area may resume once the site has been fully evaluated and mitigated to the satisfaction of the Development Services Director (or their designee). All significant artifacts collected during the implementation of the Data Recovery Plan shall be curated at a facility approved by the Development Services Director (or their designee). iii. Following the completion of mass grading operations, the applicant shall prepare a plan that addresses the temporary on- site presentation and interpretation of the results of the archaeological studies for the project. This could be accomplished through exhibition within a future community center, civic building and/or multi-purpose building. This exhibition will only be for temporary curation of those materials being actively used for interpretation and display, and that permanent curation of artifacts and data shall be at a regional repository when one is established. All significant artifacts collected during the implementation of the Data Recovery Plan shall be permanently curated at a facility approved by the Development Services Director (or their designee).

Construction activities associated with the project could inadvertently result in significant impacts to presently unknown human remains that may be uncovered during clearing and grading. 5.7-4 Human Remains Disturbance Protocol. If human remains are discovered during grading or site preparation activities within Village 8 West or off-site improvement area, the archaeological monitor shall secure the discovery site from any further disturbance. State Health and Safety Code Section 7050.5 requires that no further disturbance shall occur until the San Diego County Coroner has made the necessary findings as to the origin and disposition of the remains pursuant to Public Resources Code Section 5097.98. If the remains are determined to be of Native American descent, the coroner has 24 hours to notify the Native American Heritage Commission. The Native American Heritage Commission will then identify the person(s) thought to be the Most Likely Descendent of the deceased Native American. The Most Likely Descendent will assist the Development Services Director (or their designee) in determining what course of action shall be taken to deal with the remains. Grading operations within the affected area may resume once the site has been fully evaluated and mitigated to the satisfaction of the Development Services Director (or their designee). The Archaeological Monitor shall summarize the findings in a letter report to the Development Services Director (or their designee) following the completion of mass grading activities. Less than significant. Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Geological formations underlying Village 8 West and off-site improvement areas have a high sensitivity for paleontological resources. Therefore, construction activities would have the potential to result in significant impacts to paleontological resources. 5.7-5 Paleontological Resource Mitigation Program. Prior to the issuance of grading permits for the SPA Plan or off-site improvement area, the applicant shall provide written confirmation to the Development Services Director (or their designee) that a qualified paleontologist has been retained to carry out an appropriate mitigation program. A qualified paleontologist 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 pre-grade meeting shall be held among the paleontologist and the grading and excavation contractors. 5.7-6 Paleontological Monitor. A paleontological monitor shall be on site at all times during the original cutting of previously undisturbed sediments of the Otay Formation or Quaternary alluvial and terrace deposits to inspect cuts for contained fossils. A paleontological monitor is defined as an individual who has experience in the Less than significant. Chapter 1 Executive Summary Otay Ranch Village 8 West EIR CV EIR 10-03; SCH No. 2010062093 Page 1-42 City of Chula Vista November 2013 Table 1-2 Summary of Significant Environmental Analysis Results (continued) Environmental Issue Result of Impact Analysis Mitigation Impact Level After Mitigation collection and salvage of fossil materials. The paleontological monitor shall work under the direction of a qualified paleontologist. i. The monitor shall be on site on at least a quarter-time basis during the original cutting of previously undisturbed sediments of low sensitivity geologic formations (Holocene alluvial deposits) to inspect cuts for contained fossils. He or she shall periodically (every several weeks) inspect original cuts in deposits with unknown resource sensitivity (i.e., Quaternary alluvium). ii. In the event that fossils are discovered in unknown, low, or moderately sensitive formations, the per-day field monitoring time shall be increased. Conversely, if fossils are not discovered, the monitoring, at the discretion of the Planning Department, shall be reduced. A paleontological monitor is not needed during grading of rocks with no resource sensitivity (Santiago Peak Volcanics). 5.7-7 Fossil Discovery Procedure. If fossils are discovered, the paleontologist (or paleontological monitor) shall recover them. In most cases, this fossil salvage can be completed in a short time frame. However, some fossil specimens (such as a complete whale skeleton) may require an extended salvage time. In these instances, the paleontologist (or paleontological monitor) shall be allowed to temporarily direct, divert, or halt grading to allow recovery of fossil remains in a timely manner. Because of the potential for the recovery of small fossil remains such as isolated mammal teeth, it may be necessary in certain instances and at the discretion of the paleontological monitor to set up a screen-washing operation on the site. 5.7-8 Fossil Recording. Prepared fossils along with copies of all pertinent field notes, photos, and maps shall be deposited in a scientific institution with paleontological collections such as the San Diego Natural History Museum.

The technical study shall demonstrate to the satisfaction of the City Engineer that adequate on-site wastewater infrastructure will be available to support the transfer. The transfer of residential density shall be limited by the ability of the on-site sewerage facilities to accommodate flows. Would the project require the construction of new wastewater treatment facilities or expansion of existing facilities, the construction of would cause significant environmental effects? With respect to conveyance lines, no significant impacts have been identified for implementation of the SPA Plan and TM. However, the proposed project would require sewerage treatment beyond the City’s existing wastewater treatment capacity rights and allocated additional treatment capacity. Therefore, additional capacity would need to be acquired from the San Diego Metropolitan Sewer Authority or other sources. The means by which additional treatment capacity would be acquired is unknown and the development of additional capacity may require construction of new treatment facilities. As the location and scope of construction for any newly developed treatment facilities is unknown, the development of treatment capacity beyond the City's existing and allocated capacity may result in a potentially significant environmental impact, even understanding that such projects would likely be subject to environmental review. No mitigation is available at this time. Significant. Would the project generate sewage flows and volumes that exceed City Engineering Standards as set forth in the Subdivision Manual, as may be amended from time to time? No significant impacts related to City engineering standards have been identified for implementation of the SPA Plan and TM. No mitigation required. Less than significant. Would the project be inconsistent with the General Plan, GDP or other relevant objectives and policies regarding wastewater thereby resulting in a significant physical impact? No significant impacts related to consistency with wastewater policies have been identified for implementation of the SPA Plan and TM. No mitigation required. Less than significant.

There is sufficient existing and future landfill capacity to accommodate projected development of Village 8 West. No mitigation required. Less than significant. Would the project comply with federal, state, and local statutes and regulations relating to solid waste? The project would be consistent with all applicable statutes and regulations. No mitigation required. Less than significant. Would the project be inconsistent with General Plan, GDP, or other relevant objectives and policies regarding solid waste thereby resulting in a significant physical impact? The project would be consistent with the General Plan and GDP policies that pertain to solid waste. No mitigation required. Less than significant. 5.15.4 Recycled Water Would the project require or result in the construction of new recycled water treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? If recycled water facilities are not provided concurrently with demand, a potentially significant impact would occur. 5.15.4-1 Subarea Master Plan Preparation. Prior to approval of the first final map, the applicant shall provide a Subarea Master Plan to the Otay Water District. Recycled water facilities improvements shall be financed or installed on the site and off the site in accordance with the fees and phasing in the approved Public Facilities Finance Plan and Subarea Master Plan. The Subarea Master Plan shall include, but shall not be limited to the following information related to recycled water: i. Existing recycled water pipeline locations, size, and capacity; ii. The proposed points of connection and system; iii. The estimated recycled water demand calculations; and iv. Size of the system and number of lots to be served. 5.15.4-2 Subarea Master Plan Approval.

No significant impacts related to recycled water polices have been identified for the project. No mitigation required. Less than significant. 5.15.5 Energy Would the project increase the demand of energy resources to exceed the available supply or cause a need for new and expanded facilities? While energy consumed by future occupants of Village 8 West would not be excessive, implementation of the SPA Plan and TM has the potential to result in impacts due to increased consumption of electricity and natural gas above that analyzed in the 2005 GPU EIR, which identified a significant and unavoidable impact related to energy demand. Although development pursuant to the project would be required comply with state and city building and energy codes and regulations related to reduction in energy use, there is no long- term assurance that energy supplies will be available as needed to support subsequent development projects. No feasible mitigation measures are available for this impact. Significant. Would the project result in the wasteful, inefficient, or unnecessary use of energy? Compliance with applicable policies and the energy conservation plan would ensure that average energy consumed by future occupants of Village 8 West would not be wasteful, inefficient, or unnecessary, and would in fact be less than the regional average and less than statewide business- as-usual projections. No mitigation required. Less than significant. Would the project be inconsistent with General Plan, GDP, or other relevant objectives and policies regarding energy thereby resulting in a significant physical impact? The project would be consistent with the General Plan and GDP policies that pertain to energy. No mitigation required. Less than significant.

Project Contribution 5.1 Land Use and Planning Physical Division of an Established Community and Conflicts with Land Use Plans, Policies, and Regulations The proposed project and the cumulative projects would be consistent with City’s General Plan and the GDP, which are in turn consistent with regional plans. As such, the proposed project, as part of and combined with the cumulative projects, would not result in a significant cumulative land use impact. No No cumulative impact. Conflicts with HCPs or NCCPs The cumulative projects, including Village 8 West, would be required to demonstrate compliance with the MSCP Subarea Plan and the RMP as part of project approval. Therefore, cumulative land use impacts associated with potential conflicts with HCPs or NCCPs would be less than significant. No No cumulative impact. 5.2 Aesthetics/Landform Alteration Scenic Vistas and Scenic Resources The project, in combination with the cumulative projects, would contribute to a cumulative loss of views of natural open space. Therefore, the project would result in a cumulatively considerable contribution to a significant and unavoidable cumulative impact. Yes Cumulatively considerable and unavoidable. Visual Character or Quality A cumulatively considerable and unavoidable impact would occur related to permanent alteration to the open, rolling hills within the cumulative planning area. Yes Cumulatively considerable and unavoidable. Lighting and Glare Development of Village 8 West and cumulative growth in Otay Ranch would result in additional sources of nighttime lighting and would have the potential to result in significant cumulative impact. Yes Not cumulatively considerable. Landform Alteration The proposed project and other cumulative projects would be required to demonstrate compliance with the RMP steep slope standard. Therefore, cumulative impacts related to steep slopes would be less than significant. Yes Not cumulatively considerable. 5.3 Transportation/Traffic Traffic and Level of Service Standards and Congestion Management At full buildout, the project would result in a cumulatively considerable contribution to a significant impact at seven intersections and seven roadways segments. Yes Not cumulatively considerable with implementation of mitigation measures 5.3-1 through 5.3-20. Air Traffic Patterns, Road Safety, Emergency Access Construction of a project that would interfere with air traffic, result in a traffic hazard, or have inadequate emergency access would not affect these issues at another site. Similar to the project, cumulative development would be required to provide proper notification in compliance with Brown Field Airport Land Use Compatibility Plan when applicable and comply with all city requirements for parking, roadway design, and emergency access. Therefore, cumulative impacts would be less than significant. No No cumulative impact.

Project Contribution 5.4 Air Quality Air Quality Violations The SDAB is currently in non-attainment for ozone, PM10, and PM2.5. Therefore, a significant cumulative impact exists. Yes Cumulatively considerable and unavoidable. Sensitive Receptors Carbon monoxide concentrations at all of the studied intersections were below state and federal standards. Similar to the proposed project, new emitters of TACs would need to comply with the San Diego Air Pollution Control District criteria, such as Rule 1200. Potential diesel particulate matter emissions from commercial deliveries and bus service proposed in the adjacent villages would be subject to existing CARB regulations that would reduce emissions to the extent feasible. Therefore, a cumulative impact would not occur. No No cumulative impact. Objectionable Odors Similar to the proposed project, none of the adjacent villages propose land uses that are a typical source of odor complaints. Therefore, a cumulatively significant impact associated with objectionable odors would not occur. No No cumulative impact. Air Quality Plans A project that conflicts with the RAQS growth projections would be inconsistent with the RAQS and SIP and result in cumulative impact. As discussed in Section 5.4 under Threshold 4, the SPA Plan would exceed regional growth projections and therefore the project would result in a cumulatively considerable and unavoidable impact to consistency with adopted air quality plans. Yes Cumulatively considerable and unavoidable. 5.5 Noise Excessive Noise Levels The noise study conducted for Village 8 West included an analysis of impacts from cumulative traffic growth in 2030 to contribute to excessive noise levels on noise sensitive land uses within Village 8 West. Noise levels would potentially exceed the Chula Vista noise compatibility standards along Main Street, La Media Road, Otay Valley Road, and Street A. Therefore, a cumulative impact would occur. Yes Not cumulatively considerable. Excessive Groundborne Vibration The future cumulative projects that would potentially be located within 600 feet of Village 8 West are not considered vibration sensitive. Additionally, the existing Declaration of Covenants of Operation for the quarry includes provisions to minimize nuisance impacts from groundborne vibration. Therefore, cumulative groundborne vibration impacts would be less than significant. No No cumulative impact. Permanent Increase in Ambient Noise Levels Cumulative growth, including the proposed project, would result in six new roadway segments that would exceed 65 dBA CNEL. Cumulative growth would cause three existing roadway segments to exceed 65 dBA, and would result in an increase in traffic noise of 3 dBA CNEL or more on 12 existing roadway segments. A cumulatively considerable impact would occur on a total of 21 roadway segments. Yes Not cumulatively considerable.

Project Contribution Temporary Increase in Ambient Noise Levels The cumulative projects and the proposed project would be subject to the Chula Vista construction noise ordinance, which limits the hours of construction to 7:00 a.m. and 10:00 p.m., Monday through Friday, and between the hours of 8:00 a.m. and 10:00 p.m., Saturday and Sunday. Compliance with the Chula Vista ordinance would reduce impacts to a less than significant level. No No cumulative impact. Excessive Noise Exposure from a Public of Private Airport Impacts related to nuisance noise from over flights are site specific and are not cumulative in nature. Therefore, a cumulative impact related to aviation would not occur. No No cumulative impact. 5.6 Biological Resources Sensitive Plant and Wildlife Species, Riparian Habitat and Other Sensitive Natural Communities, Federally Protected Wetlands, and Wildlife Movement Corridors and Nursery Sites A cumulatively considerable impact would occur if a project would be inconsistent with the Chula Vista MSCP Subarea Plan. Yes Not cumulatively considerable. Local Policies, Ordinances, HCP and NCCP The cumulative projects would be required to demonstrate compliance with the MSCP Subarea Plan and the RMP as part of project approval. Therefore, cumulative impacts would be less than significant. No No cumulative impact. 5.7 Cultural and Paleontological Resources Historic Resources While any individual project may avoid or mitigate the direct loss of a specific resource, the effect is considerable when considered cumulatively. Yes Not cumulatively considerable. Archaeological Resources and Human Remains While any individual project may avoid or mitigate the direct loss of a specific resource, the effect is considerable when considered cumulatively. Yes Cumulatively considerable and unavoidable. Paleontological Resources While any individual project may avoid or mitigate the direct loss of a specific resource, the effect was considerable when considered cumulatively. Yes Not cumulatively considerable with implementation of mitigation measures 5.7-8 through 5.7-11. 5.8 Geology and Soils Exposure to Seismic Related Hazards, Soil Stability, and Expansive Soils Potential impacts related to geologic hazards in Village 8 West are not additive with other projects and are therefore not cumulatively significant. No No cumulative impact. Soil Erosion or Topsoil Loss The project and the other cumulative projects in Otay Ranch and the city would be required to comply with the federal, state, and local regulations and Chula Vista General Plan policies. Therefore, a cumulative impact related to erosion or topsoil loss would not occur. No No cumulative impact.

Project Contribution Septic Tanks and Alternative Waste Water Disposal Systems Development in the city of Chula Vista and Otay Ranch would be serviced by city wastewater and would not require septic tanks or alternative wastewater disposal systems. A cumulative impact would not occur. No No cumulative impact. 5.9 Public Services Fire and Emergency Medical Services If growth would outpace the CVFD’s ability to expand and serve new development, a cumulative impact would occur. Yes Not cumulatively considerable. Police Services If growth outpaces the Chula Vista Police Department’s ability to expand and serve new development a cumulative impact would occur. Yes Not cumulatively considerable. Schools If new growth in school-aged children would exceed the capacity of available schools, a cumulative impact would occur. Yes Not cumulatively considerable. Libraries A shortfall of approximately 28,080 square feet of library facilities currently exists. Therefore, a cumulative impact currently exists. Yes Not cumulatively considerable. Parks, Recreation, Open Space, and Trails If growth outpaces the city’s ability to provide additional facilities, a cumulative impact would occur. Yes Not cumulatively considerable. 5.10 Global Climate Change Compliance with AB 32 A project that would not comply with AB 32 would result significant cumulative impact. Yes Not cumulatively considerable. Potential Effects of Global Climate Change A project that would not exacerbate the potential effects of global climate change would result significant cumulative impact. Yes Cumulatively considerable and unavoidable. 5.11 Hydrology and Water Quality Water Quality Standards and Degradation of Water Quality Compliance with the applicable regulatory requirements would ensure that the potential water quality impacts of the proposed project, and all cumulative projects, would not result in significant cumulative impact. Therefore, a cumulatively considerable impact related to water quality would not occur. No No cumulative impact. Erosion or Siltation, Surface Runoff, and Exceed Drainage Capacity The proposed project and other cumulative projects in Otay Ranch and the city would also be required to comply with the Chula Vista General Plan policies. Therefore, a cumulatively considerable impact related to hydrology would not occur. No No cumulative impact. Groundwater Supplies and Recharge Village 8 West groundwater does not support an aquifer or local groundwater table. Therefore, no cumulative groundwater impact would occur as a result of implementation of the SPA Plan and TM. No No cumulative impact.

Project Contribution 100-Year Flood Hazards, Flooding, and Inundation Impacts related to flood and inundation hazards are site specific and not cumulative in nature. The location of one project in a flood hazard area would not affect the location of another cumulative project. Therefore, cumulative impacts related to flood and inundation hazards would be less than significant. No No cumulative impact. 5.12 Agricultural Resources Direct Conversion of Agricultural Resources and Land Use Zoning Conflicts The incremental loss of farmland as a result of the project in combination with other projects in Otay Ranch would result in a cumulatively significant impact with respect to agricultural resources. No mitigation measures are available to reduce long-term impacts to below a level of significance without restricting the development proposed in the SPA Plan and TM to allow interim agricultural uses to continue in perpetuity. Therefore, this impact would remain cumulatively considerable and unavoidable. Yes Cumulatively considerable and unavoidable. 5.13 Hazards and Hazardous Materials Transport, Use, and Disposal of Hazardous Materials and Accidental Release of Hazardous Materials The project and cumulative projects would not interfere with the implementation of General Plan Objective 19 or Policy E 20.2 and a cumulative impact related to hazardous materials would not occur. No No cumulative impact. Emergency Response and Evacuation Plans Similar to the proposed project, cumulative development would also enhance the Otay Ranch circulation network and provide additional connections to the regional circulation system. Therefore, cumulative emergency response and evacuation plan impacts would be less than significant. No No cumulative impact. Hazards to Schools, Existing Hazardous Materials Sites, Airport Hazards, Wildland Fires, and Historic Use of Pesticides Impacts related to schools sites, listing on a hazardous materials site, surrounding airports, wildland fires, and pesticide soil contamination are site specific and not cumulative in nature because impacts to individual projects would be site specific. Potential risks identified for Village 8 West or on other cumulative project sites would not affect potential risks elsewhere in Otay Ranch. Cumulative impacts would be less than significant. No No cumulative impact. 5.14 Housing and Population Population Growth Because the increase in population associated with the cumulative projects, including Village 8 West, would be accommodated by the proposed homes and town center commercial services, cumulative impacts associated with housing and population growth would be less than significant. No No cumulative impact. Displacement of Housing and People The project is currently undeveloped and would not result in the displacement of housing or people. Cumulative impacts related to displacement of housing and people are less than significant. No No cumulative impact.

Project Contribution 5.15 Public Utilities Water Impacts Long-term water supply cannot be guaranteed; therefore, any increase in water demand would be considered significant. Although the proposed project and the cumulative projects would comply with applicable regulations to reduce water demand, an increase in water demand would occur as a result in development. Cumulative impacts related to water supply would be significant and unavoidable. Yes Cumulatively considerable and unavoidable. Wastewater The location and scope of construction for any future expanded or newly developed treatment facilities is unknown and the development of additional treatment capacity may result in potentially significant and unavoidable cumulative impacts associated with construction of new or expanded treatment facilities even understanding that such projects would likely be subject to environmental review. Yes Cumulatively considerable and unavoidable. Solid Waste The Otay Landfill has sufficient capacity to accommodate Village 8 West waste disposal in combination with the city-wide cumulative increase in solid waste generation projected in the 2005 GPU EIR. The project, in combination with the other cumulative projects, would not result in a significant cumulative wastewater impact. No No cumulative impact. Recycled Water A cumulatively considerable and unavoidable impact would occur until recycled water from the South Bay Water Treatment Plant is available to meet the projected future recycled water demand. Yes Cumulatively considerable and unavoidable. Energy While individual cumulative projects may be able to reduce their energy consumption through energy conservation measures, there remains no assurance that an adequate energy supply will be available to serve the cumulative increase in energy demand. The project would result in a cumulatively considerable and unavoidable contribution to the significant cumulative impact related to energy. Yes Cumulatively considerable and unavoidable. 5.16 Mineral Resources Mineral Resource Availability and Mineral Resource Recovery Sites Because the majority of resources in the City’s MRZ-2 area would be available for extraction and extraction of resources outside of the quarry property would not be precluded, a significant cumulative impact would not occur. No No cumulative impact.
