Lettieri, AICP, General Manager PURPOSE OF ITEM: The primary purpose of this item is to distribute the Otay Ranch Final Program EIR and to brief the Planning Commissions on the content and organization of the document. STAFF RECOMMENDATION: That the Planning Commissions continue consideration of the adequacy of the Otay Ranch Final Program EIR to the Joint Planning Commission meeting of January 15, 1993. DISCUSSION: ~mmary of CEOA Process To-Date The Otay Ranch Draft Program EIR was released for public review on July 31, 1992 for a period of 80 days ending on October 19, 1992. During that time, public hearings and workshops were held to brief the City of Chula Vista and County of San Diego Planning Commissions, the Chula Vista City Council, the County of San Diego Board of Supervisors, and the public on the EIR and the Otay Ranch Project. The City of Chula Vista, as lead agency, invited written and verbal comments on the EIR during the public review period. As described below, responses have been prepared to all of the comments received during the public review period which address the adequacy of the EIR. The following documents have been prepazed since the distribution of the Otay Ranch Draft Program EIR; these documents comprise the Otay Ranch Final Program EIR: • Volume 1 -Comments and Responses to Draft Program EIR • Volume 2 -Revisions to Draft Program EIR • Volume 3 (To be distributed January 15, 1993) - Draft Mitigation Monitoring Program - Candidate CEQA Findings - Draft Statement of Overriding Considerations The final phase of the Wildlife Corridor Study was completed prior to the preparation of the Final Program EIR. The last phase involved the study of offsite wildlife comdors in order to determine the minimum viable corridor width under a variety of topographic and land use conditions. Further review at the SPA level of analysis will determine actual corridor widths. The Wildlife Corridor Study sets forth the basic standards for preserving wildlife corridors on the property. Those standazds will be met or exceeded in design of the SPA Plans. The results of these studies were applied to the development of the Mitigated Phase II-Progress Plan Alternative. The final Wildlife Corridor Study is available for review with the Otay Ranch Technical Reports at the project libraries listed in the Draft Program EIR and public notice. 110850010 Summary of Otay Ranch Scope of "Program" EIR The Otay Ranch Program EIR evaluated the overall environmental effects that could be expected from adoption of General Plan Amendments and a General Development Plan/Subregional Plan; subsequent EIRs on SPA Plans and Tentative Maps will focus on the environmental effects of specific development proposals. The Program EIR evaluated a complete range of project alternatives, assessed cumulative impacts, and considered broad policy alternatives and program-wide mitigation measures. The Program EIR focused on policy decisions, including the extent and location of development, the nature and density of development, mitigation policies, and performance standards. The subsequent approval of projects within Otay Ranch will have to comply with the minimum performance standards presented'in this EIR as adopted by the decisionmakers as conditions of project approval; subsequent studies may result in pmject-specific mitigation measures that exceed these standards or result in a complete redesign of the project. Draft Program EIR Reviewers The Otay Ranch Project Team received approximately 90 letters addressing the adequacy of the Draft Program EIR. The following is a summary of the number of letters received from agencies, organizations, and individuals: • Federal Agencies - 2 • State of California Agencies - 6 • Regional Agencies - 9 • Local Agencies - 12 • Local Organizations and Companies - 29 • Individuals - 29 A total of approximately 700 comments were received in these letters and during the four public hearings held specifically on the Draft Program EIR. Responses to all of these comments are included in the Final Program EIR. Issues Raised in Public Comments The following is a summary of the key environmental issues raised during the public review of the Draft Program EIR; this list reflects comments reiterated by multiple reviewers and comments that resulted in comprehensive responses and text revisions. The Final Program EIR includes responses to every comment that addressed the adequacy of the EIR; where appropriate, the text of the Final Program EIR has been revised in response to specific comments. CEOA Issues Adequacy of the range of alternatives -response explains the diversity of the nine alternatives evaluated in the Otay Ranch Program EIR (see response number 1 to Endangered Habitats League letter). Staff utilized the environmental constraints of the site presented in the resource sensitivity analysis as one of the basis for defining the footprint of development. Each alternative is generally consistent with respect to development area because of the environmental constraints. Therefore, the alternatives present different approaches to land use planning options, development densities, transportation 1108500/0 and circulation, park land and open space requirements, and various other factors; furthermore, the alternatives represent a wide range of environmental impacts and associated mitigation measures. Response number 14 to the Valley de Oro Community Planning Group letter further explains the purpose of the altematves. Defetral of studies to subsequent levels of development -response explains the purpose of a program EIR and the requirement for subsequent environmental review of individual projects when more detailed, project-specific information is available (see response number 3 to South County Environmental Working Group letter from Caroline Coulston). The deferral of studies is appropriate where the agency adopts performance standards to be achieved by the project. If the studies identify additional impacts, beyond those previously presented in the Program EIIt, project redesign could occur. Selection of the CEQA lead agency -response indicates agreement (i.e., the Memorandum of Understanding) between the County of San Diego and City of Chula Vista to select Chula Vista as the lead agency for preparation of the Otay Ranch Program EIR; this agreement emphasized that both jurisdictions would be actively involved in the planning and EIR process (see response number 2 to the Sweetwater Community Planning Group letter). Analysis of growth inducement -response indicates the text of the Final Program EIR has been expanded to provide additional quantification of potential growth-inducing impacts (see response number 16 to the LAFCO letter and text revisions in Section 7 of the Final Program EIR; see also response number 19 to the Endangered Habitats League letter and response number 27 to the Valley de Oro Community Planning Group letter). • Adequacy of the cumulative impact assessment -responses define the criteria for inclusion of projects in the cumulative impact assessment (see response number 9 to the Endangered Habitats League letter and response number 32 to the Valley de Oro Community Planning Group letter). Evaluation of General Plan Amendments (GPAs) -response indicates that GPAs were evaluated in appropriate sections of the Program EIR, including land use, traffic, noise, visual resources, and public services (see response number 7 to the Caroline Coulston letter). • Annexation -response clarifies that an annexation plan has not been proposed at this time (see response number 1 to the LAFCO letter), although a discussion of compatibility with LAFCO policies has been added to the Final Program EIR (see text changes in Sections 3.1 and 3.7). Land Use • Density compatibility with Jamul - response acknowledges potential incompatibilities; the Final Pmgram EIR clarifies mitigation measures regarding lot sizes contiguous to existing Jamul lots (see response number 8 to the Jamul- Dulzura Planning Group letter and revisions to the Final Program EIR). 1!0850010 BioloEical Resources Coordination with other regional open space programs (including the Multiple Species Conservation Program (MSCP) and the Natural Communities Conservation Program (NCCP)) -response indicates the relationship among these programs and explains the coordination that occurred throughout the Otay Ranch EIR process, including the coordination of preservation standards (see Table 3.3-6.1 in the Final Program EIR) and the integration of the Otay Ranch wildlife corridor study with the MSCP (see response number 2 to U.S. Fish and Wildlife Service letter and response numbers 9 and 10 to the Endangered Habitats League letter). Relationship of the Resource Management Plan (RMP) to the Program EIR - responses explain that the RMP was prepared in response to the County's Resource Protection Ordinance and its policies and guidelines are reflected in the mitigation measures. The Program EIR, with its statutory requirements, ensures the implementation of the policies and programs included in the RMP (see response number 2 to the Endangered Habitats League letter and response number 1 to the Califomia Native Plant Society letter). It is important to note that approval of the RMP is one of the discretionary actions associated with approval of the General Plan Amendments and the GDP/Subregional Plan, including the delineation of the Management Preserve within the RMP (see response numbers 1 and 2 to the Sierra Club letter from Patricia Gerrodette). The relationship of the evaluation standards in the RMP and the EIR are explained in response number 8 to the Califomia Native Plant Society letter; the response explains that the RMP addresses areas within the management preserve, whereas the EIR addresses all areas within Otay Ranch. Measures within the EIR must mitigate impacts without the benefit of a possible preserve. • Ranking of coastal sage scrub habitat -response explains the ranking based on the most highly sensitive species within the habitat and the application of habitat ranking in order to protect sensitive species and the open space system (see response number 4 to U.S. Fish and Wildlife Service letter). • Indirect and edge effects on biological resources -response describes the rationale for the conclusions of these analyses (see response number 6 to U.S. Fish and Wildlife Service letter, see also changes in the Program EIR text). • Compliance of the alternatives with the goals of the Resource Management Plan (RMP) - a table has been prepared which analyzes the level of compliance of each of the alternadves with the RMP; see Table 4.10-1.1 in Section 4.10 of the Final Program EIR. • Omission of analysis of specific species in the EIR (e.g., reptiles, invertebrates, and small mammals) -response explains use of habitat approach and "umbrella species" to determine presence of other sensitive species; summary of impacts and preservation goals for specific sensitive wildlife species has been prepared based on this approach, in response to this comment. Response also indicates that focused surveys will occur for sensitive species prior to each subsequent phase of development (see response number 2 to letter from Jimmy McGuire of San Diego State University and Table 6 in response number 3 to the Cindy Burrascano letter). These responses also explain the difficulty of maintaining a current listing of sensitive species given the ongoing changes in regulatory 110850010 status of sensitive species (see also response number 6 to Robert Fisher letter of October 12, 1992). • Impacts to vernal pool invertebrate species -response explains that vemal pool invertebrate species were assumed to occur in all vernal pool habitats on Otay Ranch, i.e., a worst-case approach to the impact assessment (see response number 2 to the Jarnie King letter) • Use of point occurrence methodology to determine existing conditions - responses explain the adequacy of the survey data and the definition of point occurrences for each sensitive plant species (see response number 7 in the U.S.. Fish and Wildlife Service letter, response number 12 of the California Department of Fish and Game letter, and response number 25 in the California Native Plant Society letter). • Specificity of mitigation -additional specificity was added to the mitigation measures for plant and animal species in the Otay Ranch Final Program EIR (see response number 15 to the U.S. Fish and Wildlife Service Letter). • Specificity of habitat restoration and rare plant mitigation plans -additional detail has been added to Section 3.3.3 of the Final Program EIR on methodologies, timeframes, and site selection for restration and mitigation. • Classification of plant community types -response explains the basis for the classification, including the classification of disturbed communities (see response number 2 to California Native Plant Society letter). • Application of Wildlife Corridor Study -response explains the timing, purpose, and results of the Wildlife Corridor Study and integration of the results into the Program EIR (see response number 6 to the South County Environmental Working Group letter from Caroline Coulston, response number 7 to the Daniel Tarr letter, and response number 13 to the Robert Fisher letter of October 12, 1992). • Importance of biological diversity of project area -response describes the analysis of the Otay Ranch open space system and the preservation of biological resources (see response number 21 to the South County Environmental Working Group letter from Nancy Nicolai). • Consideration of existing and future sensitive species -response explains the rationale for selection of the sensitive species analyzed in the Program EIR (see response number 9 to the Chaparral Greens letter). Cultural Resources • Feasibility and funding of a regional repository and interpretive center - responses explain the rationale for this mitigation measure and the responsibility for financing of the center (see response numbers 6 and 10 to the San Diego County Archaeological Society letter, response numbers 19 and 143 to The Baldwin Company letter of September 29, 1992, and response number 4 to the Charlotte McGowan letter). • Mitigation of cultural resource sites -response explains the procedure for survey, testing, and mitigation of cultural resource sites (see response number 1 nossoo~o to letter from Cazoline Avalos, response number 3 to the Charlotte McGowan letter, and response number 1 to the Adrien Myers letter). ~g~icultural Resources • Impacts to prime agricultural soils -responses explain the basis for the Prime Farmland soils classification used in the Program EIR, i.e., the Soil Conservation Service (see response number 21 to The Baldwin Company letter of September 29, 1992). Water Resources and Water Quality Surface and ground-water impacts -responses explain the basis for the determination of impacts to water resources, including the need for more detailed design plans in order to quantify water quantity and quality impacts. Further analyses will be conducted prior to SPA Plan approval once the density and location of development are determined (see response number 25 to The Baldwin Company letter of September 29, 1992 and responses 3 through 13 to Mazcia Jones letter). • Water quality of Otay Lakes -responses explain the regulatory requirements of maintaining existing quality. Text changes have further specified water quality requirements (see response number 5 to the City of San Diego Water Utilities Department letter and response number 4 to the Sweetwater Community Planning Group letter). Transportation. Circulation and Access • Analysis of impacts to specific offsite roadways -response provides additional detail on the levels of service projected for various roadways north of the study azea in adjacent communities and Otay Ranch's contribution to these levels of service (see response number 4 to the Valle de Oro Community Planning Group letter). An analysis was conducted of a segment of SR-125 north of the project area to determine Otay Ranch's contribution to these impacts; this analysis identified the need for a regional traffic impact fee to fund the construction of regional transportation facilities (see response number 6 to the Spring Valley Community Planning Group). • Financial responsibility for traffic mitigation measures -response explains that the developer of Otay Ranch will be responsible for the payment, on a fair share basis, of the cost of offsite traffic mitigation measures at each level of development (see response numbers 6 and 11 to the Valle de Oro Community Planning Group letter). • SR-125 alignment location -response indicates the alignment location is based on SANDAG's Southbay Combined Transportation Model; if CALTRANS selects an alternative location, the general plans for all jurisdictions in the Southbay region will require reevaluation (see response number 3 to the Spring Valley Cotmunity Planning Group letter). !108500!0 • Increase in traffic impacts in the absence of SR-125 - a mitigation measure has been added to the Final Program EIR (Section 3.10.3) to limit development in the absence of SR-125. • Capacity of freeway system in the Southbay region -response explains the freeway assumptions used in the traffic analysis (see response number 1 to the CALTRANS letter). • Analysis of new airport on Otay Mesa -response indicates the preliminary and speculative nature of the airport planning process; the traffic analysis will be refined at the SPA Plan level and will include the current airport traffic projections, when available (see response number 3 to City of San Diego Engineering Division letter). • Increased traffic on SR-94 -responses explain the assumptions used for the analysis of impacts to SR-94 and the need for additional analysis at the SPA level (see response numbers 2, 3, and 5 to the CALTRANS letter and response numbers 20 through 26 to Jamul-Dulzura Community Planning Group letter). • Use of Chula Vista General Plan Circulation Element network for the Composite General Plans Alternative -response explains the evaluation of a range of alternative circulation networks in the traffic impact assessment (see response number 12 to the Valley de Oro Community Planning Group letter). Air Ouality Regional air quality impacts -response explains the basis for determination of regional air quality impacts (see response numbers 1 and 2 to the Peter Watry letter). Public Services • Status of relevant agencies' strategic plans and policies regarding future water availability - a discussion of regional water issues and current planning studies by the Metropolitan Water District, the San Diego County Water Authority, and the Otay Water District has been added to the Final Program EIR (see Section 3.13.1.1). Identification of water supply for Otay Ranch -response indicates the difficulty of identifying and guazanteeing a water source and analyzing the associated impacts at this stage of the planning process (see response number 10 to LAFCO letter); a mitigation measure has been added to the Final Program EIR (Section 3.13.1.3) indicating that the water source shall be identified and approved by LAFCO and an environmental analysis conducted prior to approval of the first SPA, adoption of a development agreement, or sale of any bonds. Water service alternatives -the Final Program EIR (Section 3.13.1.2) indicates that the Otay Water District is the preferred service provider; two other jurisdictional alternatives are also evaluated. • Otay Valley Regional Park -response explains the basis for the analysis of the pazk in the Otay Ranch Program EIR (see response number 1 to Eastlake Development Company letter and Section 3.13.9 of the Final Program EIR). i~ossooro LEGEND i ~_ ~ ti r ~ .r ~ \ r ~. ~ l ~. i.

The Mitigated Phase II-Progress Plan includes the following modifications to the Phase II-Progress Plan Alternative: 1) The Eastlake parcels (equating to 169 acres) included in the Phase II-Progress Plan Alternative aze not a part of the Mitigated Phase II-Progress Plan. 2) The total number of dwelling units in the Mitigated Phase II-Progress Plan (27,179 dus) has been reduced slightly from the Phase II-Progress Plan (28,098 dus, excluding Eastlake) due to changes in some areas from residential to open space (see number 3 below). 3) Approximately 540 acres of natural open space has been added along the western edge of Salt Creek, the northern slopes of Otay River Valley, Central Proctor V alley, and southeast of Lower Otay Lake. These aeeas were formerly proposed for residential development under the Phase II-Progress Plan Altemative. 4) A 22-acre area proposed for commercial development on the Phase II-Progress Plan Alternative has been eliminated on the Otay River parcel. 5) Two optional use areas were added as follows: • Village 3 on the Otay River pazcel east of the Otay Landfill -this area is proposed as Medium and Medium-High Residential and Mixed Use but may be developed as Industrial dependent upon the future condition of the Otay Landfill. • Village 15, southeast of Lower Otay Reservoir -this area is proposed for Low, Low-Medium and Very Low Residential but may be left as natural open space as dictated by economic conditions. 6) The Scenic Comdor Overlay designation was removed from the open space areas neaz major roadways. 7) Roadway alignments were adjusted for Hunte Parkway, Otay Lakes Road, Alta Road, and Otay Valley Road to mitigate for biological impacts. 8) The boundaries of several areas proposed for development were adjusted to incorporate wildlife corridors. 9) A golf course was added to Proctor Valley Village 14 neaz the resort. 10) Approximately 35 acres of parkland has been added. The combination of these modifications to the Phase II-Progress Plan results in an overall change in the proposed number of dwelling units from 28,908 units to 27,179 units, a difference of 1,729 dwelling units (not including the units in the Eastlake parcels). Specifically, the Mitigated Phase II-Progress Plan would result in 1,780 fewer dwelling units on the Otay River Parcel, 12 more dwelling units on [he Proctor Valley parcel, and 39 1108500/0 more dwelling units on the San Ysidro pazcel. The resulting buildout population would be 79,634 persons. Table 1 lists the land use statistics for the Mitigated Phase II-Progress Plan. Residential areas account for approximately 29% of development on the Mitigated Phase II-Progress Plan as opposed to 35% for the Phase II-Progress Plan Alternative. The amount of open space proposed for the Mitigated Phase II-Progress Plan represents an increase from 58% to 62% which occurs mainly from several minor adjustments to development boundaries to incorporate wildlife corridors. Implementation of the Mitigated Phase II-Progress Plan would result in impacts similaz to the Phase II-Progress Plan analyzed in Section 4.9 of the Otay Ranch Program EIR with the exception of those issues where Phase II mitigation has been incorporated into the new land use plan. These impacts of adopting the Mitigated Phase II-Progress Plan are summarized below, as well as the recommended mitigation measures. Differences in impacts or mitigation between the two plans aze noted. Land Use Imnacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant land use impacts: • Significant change in the character of the site from open space to urban and semi-rural land including, or adjacent to, Jamul, Proctor Valley, Lower Otay Lake, and the San Ysidro Mountains. • Conflicts with County goals to limit urban development to urban areas and country towns due to development proposed in Proctor Valley and the San Ysidro Mountains. • Inconsistency with the City of Chula Vista objective to develop the Eastern Territories (Otay River parcel) with low-medium density residential development. • Incompatibility between planned residential development proposed in proximity to the Otay landfill, planned onsite industrial development, the Nelson and Sloan quarry, the San Diego Air Sports Center, SR-125, the Daley quarry site, and public/quasi-public land in Eastlake. • Potential impacts to resources currently protected by County RCA overlays in the County's Conservation Element. The impacts summarized above aze the same as those associated with the Phase II-Progress Plan described in Section 4.9.2 of the Program EIR. The majority of the changes in the original Phase II-Progress Plan would not change the degree or type of land use impacts. The Mitigated Phase II-Progress Plan incorporates the "Limited Development Areas" land use designation near the Nelson and Sloan quarry to help buffer planned residential land uses and provide for wildlife corridors. However, significant land use impacts are still likely to occur as a result of excessive noise (see discussion of noise impacts). L 0850010 10 z Q a a.

Mitigation Measures required by the Phase II-Progress Plan are all applicable to the Mitigated Phase II-Progress Plan, and no new measures aze required. Measures to reduce or eliminate significant effects are: • Implementation of landscaping, grading, buffering, and/or phasing guidelines for aeeas of the project adjacent to Eastlake and where adjacent residential and industrial development is planned on the site. • Coordination with the FAA and implementation of their required measures to avoid impacts to the San I}iego Av Sports Center (through the year 2002). • Mitigation, as described in the noise section, for areas neaz the Nelson and Sloan and Daley quames. • Addition of overlays or other restrictions on the Subregional Plan map (or an adopted RCA map) to protect the biological, cultural, and scenic resources that may need protection by existing and new county RCAs. Analysis of Significance Impacts after mitigation would remain significant regazding the change in the character of the site from open space to urban and semi-rural land and inconsistencies with county policies to preserve rural lands and City of Chula Vista goals for development of the Eastern Territories primarily with low-medium density residential development. Landform Alteration/Aesthetics Impacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant visual impacts: • A change in the overall visual chazacter of all three parcels from open space to development. • Site grading and development visible to a lazge number of people living in the area. • Views from Otay Lakes Road, Wueste Road, and Lower Otay Lake adversely affected by the planned resort development northeast of Lower Otay Lake. • Views from Proctor Valley Road and Otay Lakes Road in the San Ysidro parcel adversely affected by development proposed in central Proctor Valley and the foothills of the San Ysidro Mountains, respectively. • Reduction in scenic value of Otay Lakes Road from the realignment of Otay Lakes Road from the northern shore of Lower Otay Lake to a more northern alignment and intervening adjacent resort development. The impacts summarized above are the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.3 of the Program EIR. [108500/0 13 Mitigation The following measures must be implemented by the Mitigated Phase II-Progress Plan to reduce or eliminate significant effects. The measures aze described in more detail in Section 3.2.3 of the Program EIR. Furthermore, additional visual impact studies shall be required at the SPA level as more detailed plans are formulated. Addition of and compliance with specific landform alteration standazds to be added to the GDP/S RP that provide more stringent protection of sensitive landforms including ridgeline protection, avoidance of steep slopes and rock outcrops, contour grading, provision of natural buffering between development and significant landforms, and utilization of variable slope ratios not to exceed 2:1. • Compliance with Counry Resource Protection Ordinance No. 7631 and existing grading ordinances for cities of Chula Vista and San Diego. • Future analysis of the conceptual grading plans for all development at the SPA level to develop specific mitigation measures to reduce grading and visual resource impacts. Special attention shall be placed on grading and design of highly visible features of the project as outlined in Section 3.2.3.3 of the Program EIR. • Implement design guidelines that will pertain to future streetscapes, buildings, and villages to enhance the visual appeal of development and prevent contrasts in site character. • Identify a design review process to maximize the success of implementing the Otay Ranch design guidelines. Implement design review for all building and site plans to ensure compatible architectural styles, building materials, building proportions, landscaping, streetscape, and signage throughout each village. Analysis of Significance All measures required by the Phase II-Progress Plan are applicable to the Mitigated Phase II-Progress Plan. Impacts after implementation will remain significant for the following issues: • An unavoidable adverse change in the existing visual character of the project site. • Alteration in areas of sensitive landforms (i.e., steep slopes, Lower Otay Lake area and Otay River Valley). • Grading of steep slopes that may be visible from future development and roadways. • Realignment of the scenic roadway of Otay Lakes Road. • Development of the resort and conference center west of the Upper Otay Lake on the Proctor Valley parcel. uoasooio 1 a Biological Resources Imnacts Phase II-Progress Plan mitigation measures related to biological resoruice impacts have been incorproated into the Mitigated Phase II-Progress Plan. Adoption of the Mitigated Phase II-Progress Plan would still result in the following significant biological impacts to sensitive habitats, plants, and wildlife. These impacts are summarized below and presented in attachment A in their entirety. Habttat Overall, there would be a reduction of 540 acres of impact compared to the Phase II-Progress Plan. The Mitigated Phase II-Progress Plan retains additional acreage of sensitive habitats. Additional coastal sage scrub (207 acres) would be retained in Salt Creek, Little Cedar Canyon, near Hubbard Springs, and in a canyon in western Jamul Mountains. Additional maritime succulent scrub (23 acres) would be preserved in Salt Creek Canyon, and 3 less acres of impact to native grasslands would occur. The Mitigated Phase II-Progress Plan preserves more southern live oak riparian forest (10 acres) by pulling out of Little Cedar Canyon and the Hubbard Springs area, but impacts to alkali meadow would increase by approximately five acres. An additional two acres of southern interior cypress forest would be retained. Despite thee reductions in habitat removal, impacts to sensitive habitats would be considered significant. Refer to Attachment A for specific impacts to habitats. Plants The Mitigated Phase II-Progress Plan would retain six additional points of occurrence of Ferocactus viridescens in the Otay River parcel, but wouild impact one additional location in the Proctor Valley parcel. Two additional locations of Otay tarweed (Hemizenia conjugens) would be retained, one in Wolf Canyon and one near Poggi Canyon. One additional Tecate cypress location would be retained while two locations of Dudleya variegara would be lost. Overall, the impacts to fast and second priority species are reduced slightly. However, impacts to sensitive plants would still be considered significant. it if The Mitigated Phase II-Progress Plan focused on reducing impacts to regional wildlife corridors. Substantial improvement was made in widening the open space in Salt Creek Canyon, widening corridor R1 through Proctor Valley, widening the RS corridor south of the Air Sports Center, providing an open space connection between Poggi Canyon and the landfill, widening the R11 corridor, and eliminating development near Hubbard Springs. Impacts to the California gnatcatcher (including both development and road impacts) would be reduced by 6 to 13 pairs, while impacts to the cactus wren would be reduced from 3 to 4 pairs with the Mitigated Phase II-Progress Plan. i~ossoao 15 Mitigation The mitigation developed for the Mitigated Phase II-Progress Plan is consistent with the Phase II-Progress Plan, but has been adjusted as appropriate to reflect improvements and modifications made to the plan related to regional wildlife corridors and California gnatcatchers and cactus wrens. However, measures are still required to mitigate impacts to those resources. Refer to Attachment A for details. Analvsis of Significance Implementation of required mitigation measures would reduce many impacts to habitats and sensitive species to below a level of significance. Impacts would remain unmitigable without major project redesign for maritime sage scrub, valley needlegrass grassland, alkali meadow, snake cholla, Munz's sage, San Diego goldenstaz, Otay manzanita, coastal cactus wren, Califomia gnatcatcher, and regional raptor populations. Cultural Resources m acts Impacts to cultural resources for the Mitigated Phase II-Progress Plan can only be fully addressed after each resource has been evaluated for importance under CEQA and local criteria; therefore, all of the cultural resource sites currently known to lie within Otay Ranch aze considered to be important at this stage of planning. Potential for impacts to cultural resources is assessed based on the land use proposed in the Mitigated Phase II-Progress Plan, with areas proposed for development (i.e., land uses involving the construction of buildings and/or facilities) being assumed to have greater potential to impact resources than undeveloped land uses such as Open Space, Restricted Development, Parks, or Agriculture. Prehistoric cultural resources that would be impacted as a result of the development proposed in the Mitigated Phase II-Progress Plan aze shown in Table B-1 (Attachment B). The plan would potentially impact 130 of 213 known prehistoric sites. Historic cultural resources that would be impacted as a result of the development proposed in the Mitigated Phase II-Progress Plan aze shown in Table B-2 (Attachment B). The plan would potentially impact 21 of 49 known historic sites. • Prehistoric/historic cultural resources that would be impacted as a result of the development proposed in the Mitigated Phase II-Progress Plan aze shown in Table B-3 (Attachment B). The plan would potentially impact 22 of 30 known prehistoric historic sites. Comparison of the Mitigated Phase II-Progress Plan and the Phase II-Progress Plan for cultural resources indicates that the Phase II-Progress Plan has a significantly higher ratio (130 to 83), of prehistoric sites occurring, all or partially, within areas to be developed, to those lying completely within areas proposed for less impactive land uses (as defined above), compared to the ratio of 116 to 97 for the Mitigated Phase II-Progress Plan. The Phase II-Progress Plan ratio (23 to 26), of historic sites occurring, all or partially, within azeas to be developed, to those lying completely within proposed less impactive land use areas, however, is only slightly higher than the ratio of 21 to 28 for the Mitigated //0850010 16 Phase II-Progress Plan. The ratio (22 to 8), of prehistoric historic sites within areas of proposed development, to those within areas proposed for less impactive land uses, is the same for the Phase II-Progress Plan and the Mitigated Phase II-Progress Plan Alternatives. No difference exists between the two plans with regard to the potential for impacts to specific cultural resources of note such as the McGowan Site and the standing historic building complexes present on the ranch property. Mitigation As indicated above, at this stage of planning, with all of the prehistoric resources having not been identified, the importance of the resources is assumed rather than verified. Impacts are still general rather than specific, and development plans are still highly conceptual; therefore, development of a comprehensive mitigation plan is conceptual and necessarily programmatic rather than resource-specific for the Mitigated Phase II-Progress Plan. • The following is a synopsis of a more detailed mitigation program for prehistoric resources presented in the Resource Management Plan (RMP) and in the cultural resources technical report. For conciseness, this mitigation plan is presented as a series of interrelated stages or phases: Stage 1: The applicant shall complete an intensive, systematic survey of the remaining 17,000 acres for cultural resources in compliance with the county's requirements. Completion of the survey shall occur as soon as feasible and no later than filing of the first SPA Plan application. Stage 2: The applicant shall complete importance and boundary testing for each resource identified within the first SPA and for a sample of site types beyond the SPA but within the overall project. All Stage 2 work must be in compliance with CEQA and local guidelines to include county policies. Stage 3: The applicant shall implement appropriate mitigation measures for resources determined as important during the Stage 2 importance evaluation phase. These forms of mitigation would 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 agency approved excavation and analysis data recovery program. 4) A combination of one or more of the above measures. A preservation plan must be prepazed for those sites that aze determined to be significant. This is particularly important for sites that are proposed to be capped and landscaped to ensure their long-term preservation, or where site vandalism may present a problem and require special circumstances. • Mitigating measures for historic resources in the Mitigated Phase II-Progress Plan aze essentially the same as the measures for prehistoric resources described I 108500/ 0 17 above. The same steps and stages should be followed, although, as described in the RMP, archival research and historical documentation shall be used to augment Stage 2 field testing programs. Mitigation of impacts to historic resources through preservation may be more feasible for historic sites than for prehistoric sites because they generally comprise a smaller azea and can often be synthesized into a development plan. In the case of historic resources, Stage 3 data recovery programs shall be integrated with comprehensive programs of corresponding azchival reseazch to provide the context for, and make possible a full evaluation of, the material found on the sites. Mitigating measures for prehistoric historic resources for the Mitigated Phase II-Progress Plan are essentially the same as for prehistoric and historic resources as described above. The same steps and stages should be followed although, as described in the RMP, archival research and historical documentation may be used to augment field testing programs. Mitigation of impacts to historic components of prehistoric/historic resources through preservation may in some instances be more feasible than for the prehistoric components because they generally comprise a smaller area and can often be synthesized into a development plan. If in situ preservation is not possible, recovery of a representative amount or sample of information, both surface and subsurface, is the only other acceptable alternative. For historic components, the data recovery program will be integrated with a corresponding archival reseazch program to fully assess the significance of the material found on the sites. By creating a complementary reseazch program that fully incorporates the azchival material with the field results, many important reseazch questions can be addressed. Additionally, the applicant shall develop a plan for the onsite presentation and interpretation of the results of the archaeological studies at an interpretive center or museum. This shall be accomplished through adaptive reuse of one of the historic structures within the project or through construction of a building within one of the parks or community centers. It is expected that this interpretive center will only be for the temporary curation of those materials being actively used for interpretation and display, and that permanent curation of artifacts and data will be at a regional repository when one is established. Analysis of Significance At this level of analysis, all prehistoric, historic and prehistoric historic resources on the Otay Ranch property are considered important under CEQA. Thus, development and disturbance of the resources would constitute a significant impact of the Mitigated Phase II- Progress Plan. Implementation of the mitigation measures could reduce the project's effect; however, the impact to cultural resources would remain unmitigated at this level of analysis. Geology and Soils Imp~g Adoption of the Mitigated Phase II-Progress Plan would result,in the following significant geologic and soils impacts: 1/08500/0 18 Topographic impacts including instability of steeply inclined slopes in the mountain-valley azeas and coastal plain sections. ' • Excavation difficulties in the mountain-valley section of the project which contains metavolcanic bedrock complexes. • Potential impacts related to faulting and seismicity including ground rupture, ground acceleration and associated ground shaking, liquefaction, and landslides. • Expansive and erosive soil characteristics on some portions of the site which could impact foundations. These impacts aze the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.6 of the Program EIR. All the measures required to reduce impacts from the Phase II-Progress Plan aze applicable to the Mitigated Phase II-Progress Plan including: • Conduct site-specific geotechnical static and pseudo-static slope stability analyses prior to submittal of tentative maps providing input relative to appropriate slope design alternatives. • Conduct site-specific geotechnical studies prior to submittal of tentative maps to evaluate the rippability characteristics of the onsite earth materials. • Require that building not be allowed directly over fault trace. Conduct site- specific geotechnical study to identify specific fault locations and delineate fault setback zones, as necessary. • Adherence to the Uniform Building Code, state-of-the-art seismic design parameters of the Structural Engineering Association of California (SEAOC), and applicable local building codes. • Investigation of the site by a qualified geotechnical engineering consultant to evaluate the liquefaction potential upon submittal of tentative maps. Mitigation measures required where potential for liquefaction is determined to be moderate to high. • Site-specific geotechnical studies on all tentative maps to delineate the limits of landslides. Landslides to be completely removed or buttressed during site grading and oversaturation and subsequent loading of the soils and sediments shall be avoided. • Investigate onsite soils by qualified geotechnical consultant to evaluate erosion and expansion impacts and implement appropriate erosion control measures and selective grading and specially designed foundations. Analysis of Significance Implementation of the above measures will reduce impacts of the Mitigated Phase II- Progress Plan to below a level of significance. 110850010 19 Paleontological Resources Impacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant impacts to paleontological resources: • Physical destruction of fossil remains due to earth work activities that cut into geologic deposits (formations) within which fossils aze buried. • Burial of fossiliferous localities by construction fill operations, casual fossil collecting by amateur collectors, or heavy landscaping of pazk azeas. • Impacts to resources on the Otay River parcel from excavation work in areas underlain by either the San Diego or Otay formations which have a high potential to contain paleontologicalresources. • Development planned in azeas immediately adjacent to Proctor Valley Road and along Otay Lakes Road, north of Lower Otay Lake, on the Proctor Valley pazcel that aze underlain by highly sensitive formations. • Development planned in areas of the San Ysidro parcel with moderately sensitive formations. These impacts aze the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.7 of the Program EIR. Mitieation The following measures required for the Phase II-Progress Plan are applicable to the Mitigated Phase II-Progress Plan to eliminate significant impacts: • Retain qualified paleontologist to be present at all times during original grading of highly sensitive formations and to a lesser extent during grading of less sensitive formations. • When fossils are discovered, the paleontologist shall be allowed to recover them. • Prepare fossils and notes to be given to a scientific institution, and a final summary report prepared by a paleontologist at the end of excavation. • Create geologic/paleontologic preserves in designated areas not planned for mass excavation. Analysis of Significance After implementation of the mitigation measures, impacts will be reduced to below a level of significance. 1!0850010 20 Agricultural Resources Imnacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant impacts to agricultural resotrces: • Loss of Prime Farmland on all three parcels from conversion of farmland to residential uses and natural open space which would not allow agriculttual uses. • Loss of Statewide and Local Important Farmland on all three parcels from conversion to urban development, residential uses, and natural biological open space. • Loss of approximately 9,714 acres of the Otay Ranch property suitable for production of coastal-dependent crops. • Conflicts with current land use designations which designate all of the Otay River pazcel as Intensive Agriculture and much of the Proctor Valley and San Ysidro parcels as Multiple Rural Use. • Inconsistency with the Open Space and Conservation Element of the Chula Vista General Plan which calls for the maintenance of agriculture as a viable land use and the preservation of highly productive agricultural land. • Inconsistency with LAFCO policy which discourages conversion of prime agricultural land to other land uses other than open space. Attachment B contains the trip calculations for the Mitigated Phase II-Progress Plan. The above impacts aze the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.8 of the Program EIR. Mitigation The following measures applicable to the Phase II-Progress Plan must be implemented by the Mitigated Phase II-Progress Plan to reduce or eliminate significant effects: • Prepare agricultural plan prior to the approval of any SPA plan affecting onsite agricultural resources. Guidelines for such a plan are provided in Section 3.7.3 of the Program EIR. • Provide landscaping and buffering guidelines in the development plans at the SPA level for the areas planned adjacent to existing agricultural uses. • Set aside a small portion of the Otay River parcel that contains prime soils for an agricultural demonstration area. • Allow agricultural activities and the keeping of animals within the lazge, low- density lots planned along the northern edge of the Proctor Valley parcel, as recommended in the Jamul-Dulzura Subregional Plan. 1/0850010 21 Analx iss of Significance Impacts after implementation of the above measures will be reduced to below a level of significance with the exception of the conversion of agricultural land to urban uses and the loss of Prime Farmland. According to the state, county, LAFCO and City of Chula Vista policies and goals, the loss of an agricultural resource which has the potential to produce coastal dependent crops is considered to be a significant, unmitigable impact, regardless of the feasibility of maintaining the land in agricultural production. Mineral Resources Impacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant impacts to mineral resources: • Conflict between proposed residential development on Rock Mountain and potential future mineral extraction activities and preclusion of mineral extraction once structures aze built. • Conflict between development proposed in the azeas of the San Ysidro and Proctor Valley parcels that are within RCAs for aggregate minerals and cited in the County of San Diego Conservation Element as containing mineral resources to be protected as aggregate reserves. Until the Mineral Resources Element of the San Diego County General Plan is complete, it cannot be determined whether the mineral resources contained on these pa;cels are of regional importance. Therefore, any development that would preclude mineral extraction or is considered to be an incompatible land use would be potentially significant until a determination of significance is made by the County of San Diego or City of Chula Vista. The above impacts are the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.9 of the Program EIR. Mitigation The following measures aze the same as those required for the Phase II-Progress Plan and must be implemented by the Mitigated Phase II-Progress Plan to reduce or eliminate significant effects: • Incorporate measures in the Otay Ranch development plan to allow for mineral extraction on Rock Mountain as a designated primary land use. • Phase development on the San Ysidro and Proctor Valley pazcels to allow for mineral extraction if the County's Mineral Resources Element determines that significant mineral resources are located on the Otay Ranch property. Where possible, develop compatible land uses near the locations of future mineral extraction activities. Analysis of Significance Implementation of the above measures would reduce impacts to below a level of significance. 1108500/0 22 Water Resources and Water Quality Impacts Adoption of the Mitigated Phase II-Progress Plan would result in significant impacts to water resources and water quality as follows: • Increase in impermeable surfaces resulting in increased surface water dischazge and potential inundation of land uses located in floodplains or downstream drainage facilities. • Increase in surface water runoff velocities from an increase in impermeable surfaces thus potentially endangering the public and property. • Degradation of surface water quality from runoff from developed urban areas. • Impacts to groundwater quality and quantity from increased exposure to urban pollutants and overall increase in impermeable surfaces reducing infiltration into aquifers. The above impacts are similar to those associated with the Phase II-Progress Plan Alternative discussed in Section 4.9.10 of the Program EIR. Although the increase in natural open space proposed in the Mitigated Phase II-Progress Plan would slightly reduce impervious surfaces calculated for the Phase II-Progress Plan, the change is not substantial. Mitigation The following measures required for the Phase II-Progress Plan are applicable to and must be implemented by the Mitigated Phase II-Progress Plan to eliminate significant effects: • Inundation of project features -perform appropriate detailed hydrologic and hydraulic studies and incorporate the findings, conclusions, and recommendations into the design and construction of the project. Upgrade existing facilities or install retention detention basins as appropriate to contain surface flows, etc. • Changes in surface water flow rates -perform appropriate detailed hydrologic and hydraulic studies and incorporate findings, conclusions, and recommendations into the design and construction of the project. Incorporate erosion control measures, siltation basins, etc. into project design. • Ground-water quality -implement the improvements and plans provided in the Urban Runoff Reservoir study. Details on study content are provided in Section 3.9.3 of the Program EIR. • Ground-water quantity -implement measures to enhance recharge to aquifer systems. Analysis of Significance At this level of analysis, impacts to ground-water and surface water resources and quality aze considered significant upon development of the Mitigated Phase II-Progress Plan Alternative. Implementation of the recommended mitigation measures at the SPA and 1108500/0 23 project design levels of review would reduce the ground-water and surface water impacts to below a level of significance. Transportation, Circulation, and Access Impacts Adoption of the Mitigated Phase II-Progress Plan would result in significant transportation impacts as follows: Significant increase in roadway traffic as a result of trip generation on the site. Although cumulative project trips would decrease by 2 percent from the Phase II-Progress Plan Alternative, traffic generated by the Mitigated Phase II- Progress Plan would remain significant. The total trips generated from the Mitigated Phase II-Progress Plan is 606,353 ADT as compared to 618,850 ADT generated by the Phase II-Progress Plan Altemative. Based on the proposed land use changes within particulaz villages, onsite trip generation rates would decrease compazed to rates under the Phase II-Progress Plan as follows: Village 3 = -15% Village 4 = -27% Village 10 = -11% Village 11 = -11% • Significant impacts to onsite and offsite roadways which are expected to operate above their maximum recommended ADT volume (LOS D or worse for arterials and LOS F for freeways). • Critical intersections would experience high total daily entering volumes in excess of 65,000 vehicles per day. Tables C-1 through C-4 in Attachment C summarize the transportation impacts associated with the Mitigated Phase II-Progress Plan. The above impacts are similar to those associated with the Phase II-Progress Plan Altemative analyzed in detail in Section 4.9.11 of the Program EIR. Mitigation The measures applicable to the Phase II-Progress Plan are all applicable to and must be implemented by the Mitigated Phase II-Progress Plan to reduce or eliminate significant effects. The measures aze described in detail in Section 3.10.3 of the Program EIR. General Mitigation Measures • Prepare Transportation Demand Management Mitigation Strategies • Update General Plans • Prepaze Transportation Phasing Plans • Provide Pazallel Arterial System • Improve Mode Split • Increase Local/Regional Trip Capture RePional Freewav Mitigation Measures • Increase Freeway Capacities uoasoo~o z 4 Arterial Segment Mitigation • Increase Segment Capacities Arterial Intersection Mitigation • Increase Intersection Capacities Other Mitigation Strategies • Implement Transportation System Management Strategies • Implement Traffic Control Strategies Analvsis of Significance The above measures aze required by the Mitigated Phase II-Progress Plan to mitigate significant effects. However, some offsite roadway miles and offsite intersections would remain significantly impacted after implementation of the above measures. Air Quality Impacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant air quality impacts in San Diego County, since the County does not currently meet ambient air quality standards: • Generation of fugitive dust as a result of construction activities. • Incremental increase in pollution to the regional airshed from vehicular emissions. • Incremental increase in pollutant emissions from stationary sources including residences, commercial establishments, and community facilities primarily as a result of natural gas usage from water and space heating systems. • Increase in power plant emissions from increased energy consumption particulazly for NOX emissions. These impacts are the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.12 of the Program EIR. The number of dwelling units and amount of commercial land proposed for the Mitigated Phase II-Progress Plan are slightly less than the Phase II-Progress Plan, and the resulting emission levels would decrease proportionally. However, the decrease in emission levels would be minor, and impacts would remain significant. Mitigation The following measures are the same as those required for the Phase II-Progress Plan and must be implemented by the Mitigated Phase II-Progress Plan to reduce significant effects. A complete list of measures is included in Section 3.11.3 of the Program EIR. !10850010 25 • Implement land use policies that serve to minimize auto trips and reduce mileage traveled to service areas by designing pedestrian oriented villages close to places of employment and shopping, providing a balance of housing and employment possibilities, and providing open space and recreational facilities within or adjacent to residential areas. Implement siting and design policies that effectively reduce auto trips and increase energy efficiency. • Implement transportation-related management actions that promote and integrate mass transit into project design. Analysis of Significance The above measures aze required by the Mitigated Phase II-Progress Plan to mitigate significant effects. However, an increase in air pollutants would still occur in an azea that currently exceeds ambient air quality standards, and air quality impacts would remain significant and unmidgable. Noise Imnacts Adoption of the Mitigated Phase II-Progress Plan would result in the following significant noise impacts: • Onsite noise impacts from vehiculaz traffic as development is completed on Otay Ranch. Noise sensitive receptors located along major arterials and collector streets may be impacted by sound levels exceeding 60 CNEL. • Offsite noise impacts from vehiculaz traffic as regional traffic volumes increase due to area growth and widening of roadway segments to accommodate the increased traffic. This would impact approximately 15 percent (or 34 miles) of offside roadway miles. • Impacts to the federally endangered least Bell's vireo from elevated noise levels along roadways adjacent to riparian vegetation. • Noise adjacent to planned residential uses generated by onsite and offsite land uses such as the Nelson and Sloan Quarry, the Daley Quarry, the San Diego Air Sports Center, and the Otay Landfill. • Noise adjacent to planned residential uses generated by numerous industrial land uses adjacent to the Otay River pazcel along Otay Valley Road including auto wrecking yards. These impacts are the same as those associated with the Phase II-Progress Plan described in detail in Section 4.9.13 of the Program EIR. Mitigation The measures required for the Phase II-Progress Plan aze all applicable to the Mitigated Phase II-Progress Plan to reduce or eliminate significant effects including: 1108500! 0 2 6 • Site-specific acoustical analyses required during SPA plan review. The GDP/SRP text shall indicate where asite-specific study is required as defined in Section 3.12.3 of the Program EIR. Site-specific acoustical analyses required for all azeas adjacent to roadways proposed for widening, realignment, and/or upgrade in roadway classification through a General Plan Amendment. • Noise mitigation required for all residential land uses located in areas where the CNEL from vehicular traffic exceeds 60 dBA. Onsite mitigation includes setbacks, bamer construction, or a combination of both. Offsite mitigation may require construction of barriers on public or private property and noise insulation in existing residences. • Site-speck noise studies required for the rock quarries, Otay Landfill, and San Diego Air Sports Center operations to determine specific noise impacts and measures necessary to mitigate them. • Site-specific noise studies required for all development adjacent to least Bell's vireo habitat. Analysis of Significance Reduction of noise impacts from the sources outlined above to below a level of significance may not be feasible, and noise impacts after implementation of the above measures may remain significant. Public Services and Utilities Adoption of the Mitigated Phase II-Progress Plan would result in the following sighificant impacts to public services and utilities: Water Availability and Demand The total water demand for the Mitigated Phase II-Progress Plan is estimated at 21.4 mgd for average day use. Water conservation measures would reduce the potable demand by 121 gallons per day per dwelling unit, for a savings of 3.3 mgd or 15 percent. Water service and attendant facilities are proposed for all pressure zones. Storage capacity and filtration plant capacity would be purchased from the City of San Diego. Facility phasing would require construction on the Otay River parcel first, followed by incremental system expansion. The reclaimed water demand for the Otay River pazcel is 2.80 mgd under the Mitigated Phase II-Progress Plan. A distribution and delivery system similaz to the Phase II- Progress Plan would be required; however, this plan would require less capacity in the wastewater reclamation facility. Facts • Significant impacts include the unanswered question of which water jurisdiction will ultimately serve the project, the provision of facilities sufficient to serve the project, and the issues of water reclamation and future water availability. //0850010 27 The following mitigation measures are the same as those required for the Phase II- Progress Plan Alternative and must be implemented by the mitigated Phase II- Progress to reduce significant effects. Please refer to Section 3.13.1.3 of the Program EIR for a complete description of these mitigation measures. • Annexation of land to the appropriate water jurisdiction. • The preparation of a Water Master Plan by the project applicant in accordance with the standards of the appropriate water jurisdiction. Details on the required contents of the master plan are contained in Section 3.13.1.3 of the Program EIR. • If required by the appropriate water district, written verification shall be obtained from the water district that water will be adequately provided. Wastewater and Sewer Service The total sewage generation for this plan is estimated at 10.02 mgd for average flows. This plan would provide gravity flow through Poggi and Telegraph Canyon drainage basins. The estimated flow from Poggi and Telegraph Canyon drainage basins is 2.20 million gallons per day. Under this plan, approximately 7.8 mgd of wastewater flow would be conveyed to the Otay River Valley. Capacity in the wastewater reclamation facility would be required for this plan, in order to utilize reclaimed water for irrigation. The interceptor sewers and treatment plant would require less capacity than the Phase II- Progress Plan. The initial phases of development would begin in the Telegraph and Poggi Canyon basins to utilize existing City of Chula Vista interceptors. Facts • Significant wastewater and sewer service impacts include the unanswered questions of which sewer jurisdiction would serve the project, where the project's wastewater would be treated, and how facilities would be funded. Mitigation Mitigation measures are the same as those required for the Phase II-Progress Plan. Please refer to Section 3.13.2.3 of the Program EIR for a complete description of these mitigation measures. • Annexation of land to the appropriate sewer jurisdiction. The preparation of a Sewer Master Plan by the project applicant in accordance with the standards of the appropriate jurisdiction. Details on the required contents of the master plan are contained in Section 3.13.2.3 of the Program EIR. • If a requirement of the appropriate sewer district, written verification shall be obtained from the sewer district prior to SPA Plan approval that sewer service will be adequately provided. /10850010 28 Integrated Waste Management Imnacts The total waste generation for the Mitigated Phase II-Progress Plan is estimated at 35,333 tpy. This demand, generated by the 27,179 units and the additional population of 79,634, would result in potentially significant impacts to solid waste management in South County. This plan would require an integrated waste management system similar to the Phase II-Progress Plan, although the materials recovery facility and composting facility may be scaled back to serve the projected demand. Mitigation • Mitigation measures required under the Mitigated Phase II-Progress Plan include the preparation of an Integrated Waste Management program by the project applicant prior to SPA plan approval, and the project's participation in this program during all phases of SPA development. The program contents are detailed in Section 3.13.3.3 of the Program EIR. Police Protection Impacts A proportional calculation based on population was used to determine the demand for law enforcement facilities under the Mitigated Phase II-Progress Plan. This results in a demand for approximately 111 law enforcement personnel and 22,683 square feet of office space. Due to the fact that detailed development and facility plans are not available at this time, the project-specific impacts of the Mitigated Phase II-Progress Plan cannot be determined. At this stage of review, it has been determined that the unresolved issues with respect to the provision and funding of services and facilities constitute significant impacts. Mitigation Mitigation measures required by the Mitigated Phase II-Progress Plan are described in detail in Secdon 3.13.4.3 of the Program EIR and include: • The preparation of a comprehensive Law Enforcement Master Plan by the project applicant in accordance with the standards of the appropriate service provider. Fire Protection and Emergency Medical Service The Mitigated Phase II-Progress Plan would require provision of four fire facilities, the same number of facilities required to serve the Phase II-Progress Plan. Emergency service would require two facilities. The emergency service facilities would be co-located with the fue facilities. Imnacts • Potentially significant impacts to the provision of fire protection and emergency medical service. This determination has been made due to the current lack of //08500/0 29 detailed development and facility plans which would be made available during the SPA Plan review process. Mitigation The mitigation measure required under this plan is identical to the Phase II- Progress Plan and is described in detail in Sections 3.13.5.3 and 3.13.6.3 of the Program EIR. • Prepazation of a comprehensive Fire Master Plan by the project applicant in accordance with the appropriate service provider requirements. The master plan shall demonstrate compliance with City of Chula Vista and County of San Diego fire equipment and response time provisions for emergency medical service. Schools The estimated 79,634 total population under the Mitigated Phase II-Progress Plan would generate demand for facilities necessary [o serve approximately 16,840 students. Approximately 18 schools on approximately 291 acres would be required. Imnacts • The lack of detailed development and facility plans at this stage of analysis make it difficult to determine the project-specific impacts on schools. Further environmental review is required prior to SPA Plan approval to ensure the adequate provision of school facilities. Until that time, this plan is considered to have potentially significant impacts on schools. Mitigation Mitigation measures required under this plan are identical to the Phase II-Progress Plan and are discussed in detail in Section 3.13.7.3 of the Program EIR. These measures include: Prepazation of a Schools Master Plan by the project applicant in close coordination with the affected school districts. Details on the master plan contents are contained in Section 3.13.7.3 of the Program EIR. • Provide documentation to the appropriate jurisdiction confirming school district satisfaction of facility funding. Libor ~ ervice The estimated 79,634 total population under the Mitigated Phase II-Progress Plan would generate demand for 39,817 squaze feet of library space. An additional 238,902 books would also be required for the residents of Otay Ranch under this plan. Imnacts • The lack of detailed development and facility plans at this stage of analysis make the project-specific impacts under this plan difficult to determine. Further environmental review would be required at the SPA Plan level, similar to the Phase II-Progress Plan, to ensure adequate facilities and staff would be !!08500!0 3 0 available to serve the proposed project. At this stage of review, it has been determined that the unresolved issues with respect to the provision and funding of services and facilities constitute significant impacts. Mitigation The mitigation measure required under this plan is discussed in detail in Section 3.13.8.3 of the Program EIR. • The prepazadon of a Library Master Plan by the project applicant in accordance with the criteria of the applicable jurisdiction. Pazks. Recreation. and Open space The demand for neighborhood and community parks under the Mitigated Phase II- Progress Plan would be for approximately 240 acres. Based on the goal of IS acres per 1,000 population, the demand for regional parks would be 1,200 acres. Impacts The lack of detailed development and facility plans at this stage of analysis make the full extent of this plan's impact on parks, recreation, and open space difficult to determine. Further environmental review would be required prior to SPA Plan approval to ensure the provision of adequate pazks, recreation, and open space. Until that time, this plan is considered to have potentially significant impacts on parks, recreation, and open space with respect to siting, funding, and phasing. Mitigation Mitigation measures required under the Mitigated Phase II-Progress are identical to the Phase II-Progress Plan Alternative. The following measures are discussed in detail in Section 3.13.9.3 of the Program EIR. • Preparation of a Parks, Recreation and Open Space Master Plan by the project applicant in accordance with applicable standards for parkland acreage and recreation facilities. • Dedication of land in accordance with requirements or payment of fees in lieu of dedication would mitigate any impacts to below a level of significance. Electricity and Gas Im acts Additional substations and associated distribution lines would be required to serve development under the Mitigated Phase II-Progress Plan; placement of these facilities and associated impacts would be determined at the SPA Plan level. Mitigation All the measures required to reduce impacts from the Phase II-Progress Plan must be implemented by the Mitigated Phase II-Progress Plan including: //08500/0 31 • The project applicant shall work with SDG&E during all stages of electrical and gas facilities planning to minimize disturbance to sensitive resources. • Land uses adjacent to the SDG&E transmission lines shall be subject to review and comment by SDG&E. Health and Medical Facilities Based on the same methodology utilized in Section 3.13.11 of the Program EIR, it was estimated that the following health and medical facilities would be required under the Mitigated Phase II-Progress Plan: • 1 public health satellite office • 2.2 99-bed nursing homes • 1.6 commercial home health care offices • 5 public and private community meeting spaces • 2 ambulatory pavilions • 137 commercial physician, dentist, chiropractic, mental health, therapeutic, laboratory, and medical services and supply offices Mitigation Mitigation measures under this plan are described in detail in Section 3.13.11.3 of the Program EIR and include: • Involvement of appropriate govemmental agencies and service providers during all stages of planning. Specific needs and siting of appropriate facilities shall be identified by the project applicant in corporation with health care providers prior to SPA Plan approval. Senior and Social Service Facilities Impacts Demand for senior and social service facilities is dependent upon the number, location and demographics of the proposed project's population. Although there aze currently no statutory requirements for the provision of senior and social services, it is expected that the Mitigated Phase II-Progress Plan would have significant impacts on the provision of these services as the proportion of the population over the age of sixty continues to increase and the demand for social services in the region continues to grow. Mitigation Mitigation measures under this plan are described in detail in Section 3.13.12.3 of the Program EIR and include: • Involvement of appropriate governmental agencies and service providers during all stages of planning. 110850010 3 2 Specific needs and siting of appropriate facilities shall be identified by the project applicant in cooperation with service providers prior to SPA Plan approval. hil The estimated population of 79,634 residents would generate demand for 3,210 formal child care slots. It is estimated that 52 percent of the needed child caze would be provided by large group facilities with an average capacity of 90 children. Therefore, the Mitigated Phase II-Progress Plan would generate a demand for approximately nineteen 90-slot child caze facilities. Assuming adequate child care facilities are provided as deemed necessary, no impacts would occur. Imnacts • Although there are currently no mandated requirements for the provision of child caze facilities, project deve]opment is expected to have significant impacts on the provision of these services as the population increases in the project area. Mitigation Mitigation measures include the provision of child care facilities as deemed necessary during the policy development process. Animal Control Im c • The additional population in the South County area generated by development under the Mitigated Phase II-Progress Plan would increase the demand for animal control facilities, resulting in a potentially significant impact. Mitigation Mitigation measures require that the project applicant participate in programs to equitably share the funding of animal control facilities and designate animal control facilities to provide adequate squaze footage of shelter space per dwelling unit to the satisfaction of the appropriate jurisdiction. Analysis of Sienifican At this level of analysis, the additional 27,179 homes and associated population of 79,634 residents as a result of the Mitigated Phase II-Progress Plan would result in significant impacts to the provision of public services and utilities. Implementation of the mitigation measures outlined above at the SPA-level would mitigate project-specific impacts to below a level of significance. Risk of Upset Impacts Adoption of the Mitigated Phase II-Progress Plan would result in significant impacts to risk of upset as follows: !!08500!0 3 3 • Exposure to soils in the area of the ranch operations center contaminated with petroleum hydrocazbons and pesticides in excess of State of California standards. • Potential danger of an accident occurring due to disturbance of any unexploded ordnance in the southern portion of the Otay River pazcel previously used as the Brown Field Bombing Range. • Exposure to contaminated material in the areas adjacent to the Otay Landfill as a result of previous use of the landfill for hazardous waste disposal. The above impacts are the same as those associated with the Phase II-Progress Plan Alternative described in Section 4.9.15 of the Program EIR. Mitigation The mitigation measures proposed for the Phase II-Progress Plan aze applicable to the Mitigated Phase II-Progress Plan: Soil and ground-water testing shall occur in the ranch operations center area potentially affected by the previous disposal of hazardous waste or historic pesticide use. The purpose of the testing shall be to identify areas of contamination in excess of federal and state standards. Should areas of excess contamination be identified, remediation shall occur prior to residential development. • The applicant shall notify prospective buyers and the California Department of Health Services (DHS), as required, regazding of their intention to develop the azea adjacent to the Otay Landfill and the Appropriate Technologies II hazardous waste facility. • A survey shall be conducted of the Brown Field Bombing Range by the Army to identify the presence of any unexploded ammunition. Should unexploded ordnance be located on the property, appropriate measures shall be taken for removal of the material. The transport of hazazdous waste on existing and future roadways shall be conducted in accordance with the California Code of Regulations (CCR) and the Code of Federal Regulations (CFR). These regulations identify Department of Transportation (DOT) approved methods for packaging and containerizing hazazdous waste and site appropriate options and procedures relative to the handling and transportation of these wastes. • The need for emergency evacuation routes and other emergency facilities shall be determined at the SPA level based not only on the presence of offsite industrial uses, but on those that may occur onsite as well. Analy,is of Significance Implementation of the above measures will reduce impacts of the Mitigated Phase II- Progress Plan to below a level of significance. 1/0850010 34 ATTACHMENT A SUMMARY OF BIOLOGICAL RESOURCES IMPACTS Attachment A BIOLOGICAL RESOURCES ANALYSIS FOR MITIGATED PHASE II-PROGRESS PLAN A . Impacts Phase II-Progress Plan mitigation measures related to biological resoruice impacts have been incorproated into the Mitigated Phase II-Progress Plan. Adoption of the Mitigated Phase II-Progress Plan would still result in the following significant biological impacts to sensitive habitats, plants, and wildlife. These impacts are summarized below and presented in attachment A in their entirety. Overall, there would be a reduction of 540 acres of impact compared to the Phase II- Progress Plan. The Mitigated Phase II-Progress Plan retains additional acreage of sensitive habitats. Additional coastal sage scrub (207 acres) would be retained in Salt Creek, Little Cedar Canyon, near Hubbard Springs, and in a canyon in western Jamul Mountains. Additional maritime succulent scrub (23 acres) would be preserved in Salt Creek Canyon, and 3 less acres of impact to native grasslands would occur. The Mitigated Phase II-Progress Plan preserves more southem live oak riparian forest (10 acres) by pulling out of Little Cedar Canyon and the Hubbard Springs area, but impacts to alkali meadow would increase by approximately five acres. An additional two acres of southern interior cypress forest would be retained. Despite thee reductions in habitat removal, impacts to sensitive habitats woiuld be considered significant. The following impacts acreages calculated for the MiTigated Phase II-Plan, include development areas and road way impacts. Atypical roadway width of 200 feet was utilized for roadways outside development bubbles to estimate potential habitat reductions. Note that the impact acreages for habitats in the Final Program EIR do not include roads that occur outside development bubbles. Comparisons between the Mitigated Phase II- Progress Plan presented here and the Phase II-Progress Plan in the Program EIR should be made with this in mind. For example, the increase in wetland impacts is due in large part to the inclusion of roads. • Coastal sage scrub including disturbed coastal sage scrub would be impacted by an estimated 2,760 acres (25 percent). Impacts to this habitat without including road impacts would be 2,643 acres (24 percent). • Maritime succulent scmb would be impacted by 56 acres (20 percent). Impacts to this habitat without including road impacts would be 37 acres (13 percent). • Wetland habitats would be impacted by 12 percent (94 acres) or 5 percent (41 acres) without road impacts. This acreage includes 42 acres (28 percent impact) of alkali meadow, 0.9 acres (1 percent) of southern live oak riparian forest, 0.7 acres (5 percent) of southern willow scrub, 48 acres (9 percent) of floodplain scrub, and 1.6 acres of freshwater marsh/aquatic habitat. • Vernal pool habitat would be impacted as a result of industrial development of the southern extent of the J30 and J31 complexes on Otay Mesa and development of several small vernal pool groups on all three pazcels, including 110850010 A•t M2, R1, R4, K9, and K14. The watershed of the J29-30, J31, K6, and R2 vernal pool complexes may be affected by proposed adjacent land uses. • Valley needlegrass grassland would be reduced by 169 acres (64 percent); the majority of this loss would occur in the vicinity of the K6 vemal pool complex on the Proctor Valley pazcel. • Coast live oak woodland would be reduced by 0.2 acres, (0.1 percent). • Southern interior cypress forest would be impacted by six acres (4 percent) on the San Ysidro pazcel. The Mitigated Phase II-Progress Plan would retain six additional points of occurrence of Ferocactus viridescens in the Otay River pazcel, but wouild impact one additional location in the Proctor Valley parcel. Two additional locations of Otay tarweed (Hemizenia conjugens) would be retained: one in Wolf Canyon and one near Poggi Canyon. One additional Tecate cypress location would be retained, while two locations of Dudleya variegata would be lost. Overall, the impacts to first and second priority species are reduced slightly. However, impacts to sensitive plants would still remain significant. Three high-priority state or federally threatened or endangered plant species would be significantly impacted. These are the San Diego thorn-mint (Acanthomintha ilicifolia), San Diego button-celery (Eryngiurn aristulaturn var. parishii), and Otay tarweed (Hemizonia conjugens). The two known populations of San Diego thorn-mint on the Ranch would be lost by development on the Proctor Valley pazcel (Village 13). Four vernal pools supporting San Diego button-celery on Otay Mesa in the southern part of the J31 complex would be impacted. Otay tarweed would be impacted in Poggi and Wolf Canyons, on the north slope of Rock Mountain, on the slopes of the Otay River Valley, and at the northwest end of Salt Creek. Eight second priority species would be significantly affected. These aze Otay manzanita (Arctostaphylos otayensis), Orcutt's brodiaea (Brodiaea orcuttii), variegated hasseanthus (Dudleya variegata), San Diego navarretia (Navarretia fossalis), San Diego barrel cactus (Ferocactus viridescens), San Diego goldenstaz (Muilla clevelandii), snake cholla (Opuntia parryi var. serpenrina), and narrow-leaved nightshade (Solanum tenuilo6atum). • Seven third-priority species would be significantly affected. These aze delicate clazkia (Clarkia delicata), San Diego County stipa (strips diegoensis), Orcutt's bird's beak (Cordylanthus orcuttianus), San Diego marsh elder (Iva hayesiana), Munz's sage (Salvia munzii), Greene's ground-cherry (Physalis greenei), and San Diego sunflower (Viguiera laciniata). • Two fourth-priority species, California Adder's tongue fern (Ophioglossum lusitanicum ssp. californicum) and Coulter's Matilija poppy (Romneya coulteri) would be significantly impacted. it if Features of the Mitigated Phase II-Progress Plan aze focused on reducing impacts to regional wildlife corridors. Substantial improvement was made over the Phase II-Progress 1/0850010 p.Z Plan in widening the open space in Salt Creek Canyon, widening comdor R1 through Proctor Valley, widening the RS corridor south of the Air Sports Center, providing an open space connection between Poggi Canyon and the landfill, widening the R11 corridor, and eliminating development near Hubbard Springs. Impacts to the Califomia gnatcatcher (including both development and road impacts) would be reduced by 6 to 13 pairs, while impacts to the cactus wren woiuld be reduced from 3 to 4 pairs with the Mitigated Phase II- Progress Plan. The state and federally-listed least Bell's vireo (Vireo bellii pusillus) would be affected by La Media Road crossing of the Otay River Valley and the road crossing of Dulzura Creek. Additional affects would occur from SR-125, Heritage Road, Alta Road, and proposed development of the San Ysidro pazcel adjacent to Dulzura Creek. The southwestern willow flycatcher (Empidonax trailli extimus) occupies similar habitat to the least Bell's vireo, and could be similazly impacted. The Califomia gnatcatcher (Polioptila californica) would be directly impacted by development at a minimum of 38 locations and byroad impacts at an additional 15 locations. The total impacts represent a minimum of 53 of the estimated 144 pairs onsite or 37 percent. Additional significant impacts to gnatca[chers could occur from development (6 locations) and road construction (1 location). These additional impacts need to be evaluated at the SPA level when more detailed development plans are available. If these impacts aze significant, 60 of 144 gnatcatcher pairs (41.7 percent) would be impacted. The coastal cactus wren (Campylorhynchus brunneicappillus cousei) would be directly impacted at 12 locations, all on the Otay River pazcel; an additional 9 locations will be impacted by road construction. The total impact of 21 locations represents 35 percent of the onsite locations. An additional location could be impacted by development. If this is a significant impact at the SPA level, then 22 of 60 cactus wren locations (36.7 percent) would be impacted by the mitigated Phase II-Progress Plan. • Habitat for three invertebrates, two species of fairy shrimp (Streptocephalus wootoni) and San Diego vernal pool fairy shrimp (Branchinecta sandiegensis), and Quino checkerspot (a butterfly, Euphydryas editha quino) will be affected by impacts to vernal pool habitat. • Habitat for the Harbison's dun skipper (Euphyes vestris harbisoni) could be affected where impacts to southern live oak riparian forest occur in the San Ysidro parcel. • Significant reduction of upland habitats by over 25 percent will reduce potential habitat for Hermes' copper (Lycaena bermes). • Reduction in Tecate cypress habitat on the San Ysidro parcel will impact potential habitat for Thorne's hairstreak (Mitoura thornel). • Potential habitat for the California red-legged frog (Rana aurora draytonii) and the southwestern pond turtle (C[emmys marmorata pal[ida) will be impacted with the reduction of 1.5 acres of aquatic azeas. . 110850010 A-3 • Breeding habitat for the tricolored blackbird would be impacted by construction of SR-125 in the Otay River Valley. Foraging habitat in agriculture lands in the San Ysidro parcel would also be impacted. The loss of sensitive habitats could impact 45 second-priority species with USFWS candidacy and/or CDFG Species of Special Concern status. Second priority species which would be impacted include: San Diego horned lizard, orange-throated whiptail, coastal western whiptail, coastal rosy boa, two- striped garter snake, northern red diamond rattlesnaked osprey, northern harrier, sharp-skinned hawk, Cooper s hawk, ferruginous hawk, golden eagle, merlin, prairie falcon, burrowing owl, Califomia horned lark, loggerhead shrike, yellow warbler, yellow-breasted chat, southern California rufous- crowned sparrow, Bell's sage sparrow, San Diego black-tailed jackrabbit, and American badger. Other second-priority species which could be impacted depending on their presence and distribution within proposed development areas include: western spade foot toad, arroyo southwestern toad, San Diego banded gecko, sandstone night lizard, Coronado skink, silvery legless lizard, San Diego ringneck snake, coast patch-nosed snake, San Diego mountain kingsnake, mountain plover, long-billed curlew, long-eared owl, short-eared owl, California leaf-nosed bat, Townsend's big-eazed bat, pallid bat, Califomia mastiff bat, Pacific little pocket mouse, northwestern San Diego pocket mouse, Dulzura Califomia pocket mouse, southern grasshopper mouse, and San Diego desert woodrat. • Key raptor foraging and nesting areas will be developed in Proctor Valley, on the southern slopes of the Jamul Mountains, at the east end of the San Ysidro pazcel, south of Dulzura Creek at the east end of Lower Otay Lake, and on Otay Mesa. • Wildlife Corridors - In evaluating impacts to wildlife corridors, the assumption was made that "Limited Development Areas" would remain in natural open space with only road and utility alignment crossings impacting this open space. The following wildlife movement corridors would remain impacted under the Mitigated Phase II-Progress Plan. Poggi Canvon to Wolf Canvon -This regional gnatcatcher and cactus wren corridor would be impacted by the Paseo Ranchero Road crossing. It could also be impacted by any offsite development in the northeast comer of the county landfill. Wolf Canyon to Salt Creek -This regional gnatcatcher and cactus wren corridor would be impacted by a number of road crossings, including Rock Mountain Road, Otay Valley Road, La Media Road, SR-125 and the associated transit corridor, and Alta Road. Wolf Canyon to Otay River Valley -This corridor for bobcats would be impacted by the crossing of Otay Valley Road and could also be constrained by development on the west side of Wolf Canyon. Otay Valley Corridor -This regional corridor for mammals would be impacted by road crossings at Heritage Road, La Media Road, SR-125 and the transit corridor, and Alta road. 1/0850010 A-4 Salt Creek Canyon -This regional corridor would be impacted by the Alta Road crbssing at the mouth of Salt Creek Canyon. In evaluating impacts to wildlife corridors, the assumption was made that limited development azeas would remain in natural open space with only road and utility alignment crossings impacting this open space. O'Neal Can, -This regional corridor would be impacted by the Alta Road alignment through O'Neal Canyon. Corridor R1 -This regional corridor would be impacted at several different locations by proposed roads and development. Impacts would occur at the north end of the disjunct L-shaped parcel. At this location, low density development intrudes into an important ravine which channels animals into the Sweetwater Reservoir. Proctor Valley Road would impact corridor R1 where it crosses this corridor in Proctor Valley. Low-Medium and Very Low (I.MV) residential development on the south side of the corridor and east of Proctor Valley Road, extends into the corridor in an azea where it is important that the comdor remain wide. Across the corridor, to the north, K6 and other development extends into the corridor and could impact it depending on detailed development plans. East of the K6 development, the corridor is blocked by low density development which spills into the canyon from the north. This canyon is extremely important for directing animals from Proctor Valley into the Jamul Mountains and on into the San Ysidro Mountains. Corridor R2 -This regional corridor is significantly constrained along its southern portion by Low, LMV and Medium-High (MH) development on the west side. Low density development on a knoll across from the parcel which is not a part of Otay Ranch, would also impact this corridor. The siting of a park at the south end is also a potential impact depending on the design, land uses, and final location of this pazk. Otay Lakes Road would cross this comdor twice and would impact animal movement. Corridor L4 -This local corridor is blocked by development from Proctor Valley village 14 and is further impacted by Proctor Valley Road along most of its length. Corridor RS -This corridor is not impacted as long as the Sensitive Resource Study Area (SRSA) south of Lower Otay Lake is retained in natural open space. Corridor L8 -This local corridor is blocked at its north end by development on both side. Comdor R10 -This regional corridor could be constrained at its northern end by VL development which spills over into Cedar Canyon. Corridor R11 -This regional comdor is significantly constrained by LMV development along its western side neaz Otay Lakes Road. Expansion of the Otay Lakes Road crossing of this corridor would also impact it. 110850010 A-5 B . Mitigation The mitigation developed for the Mitigated Phase II-Progress Plan is consistent with the Phase II-Progress Plan, but has been adjusted as appropriate to reflect improvements and modifications made to the plan related to regional wildlife corridors and California gnatcatchers and cactus wrens. However, measures aze required to mitigate impacts to those resources. Habitats ))~gan Coastal Sage Scrub. • Major redesign of the project to retain 80 percent of the coastal sage scrub onsite and the key areas identified below. • Redesign may be necessary to minimize or avoid impacts in: - Salt Creek (all existing coastal sage scrub (CSS) - Poggi and Wolf canyons (all existing CSS) - Porttons of Rock Mountain and existing CSS on north side of Otay River Valley - Patches of CSS south of the east end of Lower Otay Lake and Dulzura Creek • Restoration of approximately 1,500 acres of identified high priority areas within the Otay River parcel (see Figure 3.3-8 in the Final Program EIR). Mitigation shall be complete and demonstrated successful prior to impact. Acquisition and long-term protection of approximately 1,000 acres of coastal sage scrub offsite. This will mitigate the impacts remaining after avoiding 80 percent of onsite habitat and restoring the high priority. Offsite mitigation shall not be used in place of avoidance or onsite restoration, but is necessary to reduce impacts to below a level of significance. Offsite mitigation shall be purchased in areas identified by the NCCP and MSCP programs as key areas for a South County biological preserve. The mitigation program shall consist of a four-year experimental phase and an eight-yeaz phase for the full-scale restoration. The mitigation shall be initiated with the first SPA. Because the restoration must be successfully completed prior to impact of sensitive habitats, the first SPA shall be located within non- sensitive habitats. The experimental phase of the mitigation program includes collection of biological data to refine the locations for restoration, to obtain baseline information on adjacen[ undisturbed habitats, and ro develop the most effective restoration methodologies. The full-scale restoration shall include a one-to-three year period for site preparation (i.e. weed removal and planting) and alive-year period for quantitative monitoring and assessment of restoration success. Horticultural monitoring and remedial maintenance will be ongoing. The mitigation must meet the success criteria and be satisfactory to the appropriate jurisdiction before impact to the original sensitive habitat can occur. • Potential indirect impacts shall be mitigated by providing a minimum 100-foot buffer area around all preserved coastal sage scrub. No development landscaping or clearing for fire management shall be allowed within the buffer azea. 1108500!0 A-6 Maritime Succulent Scmb. • Mitigation for the impacts to maritime succulent Scmb will require redesign of the project to preserve 98 percent of this habitat onsite. Restoration of maritime succulent scrub to offset remaining impacts is discussed in conjunction with Diegan coastal sage scrub above. Existing habitat acreage is scattered throughout the Otay River pazcel and is particularly sensitive where cactus thickets aze present. Effort shall be made to protect disjunctive stands especially where they support such thickets and can logically be tied to a larger open space network. Flood~l in Scrub. Southern Willow Scrub, and Aauatic/Freshwater Mazsh. Mitigation for impacts to floodplain scrub, southern willow scrub, and aquatic/freshwater marsh habitats includes redesign of the project to retain 95 percent of these habitats and restoration/enhancement of disturbed wetland habitat to mitigate the remaining impacts. Restoration/enhancement shall occur in the Otay River Valley within tamarisk/mulefat scrub habitat (see Figure 3.3-8 in the Program EIR). Impacts shall be minimized through placement and design features and shall be mitigated at an appropriate ratio based on habitat type and quality and whether pre-establishment of in-kind habitat has occurred. Compensation would be approved by the California Fish and Game through the Streambed Alteration Agreement and/or the Corps of Engineers 404 permit process, as appropriate. Adequate disturbed and/or low quality floodplain acreage is available within the Otay River Valley to adequately mitigate wetland impacts. Non-native Grassland. The provision of a large open space system with open habitats and native grasslands will partially mitigate this impact; however, not to a level below significance. Valley Needlegrass Grassland. The loss of disturbed valley needlegrass grassland would require major redesign of the project to preserve 50 percent of this habitat. Habitat restoration shall be implemented to mitigate the remaining impacts. Areas to be retained for preservation and restoration include the disturbed perennial grassland contiguous with the K6 vernal pool complex and large San Diego thorn-mint population north of Lower Otay Lake, and in selected areas in the Otay River pazcel to be determined by subsequent field transect studies. A mitigation program including a four year experimental phase and an eight year maintenance and monitoring program is required. /!0850010 A-7 Alkali Meadow. Redesign of the project to preserve 998 percent of this habitat onsite and restoration of disturbed alkali meadow habitat in the Proctor Valley parcel to offset the remaining impact. Impacts shall be minimized through placement and design features and shall be mitigated at an appropriate ratio based on habitat type and quality and whether pre establishment of in-kind habitat has occurred. Compensation would be approved by the California Fish and Game through the Streambed Alteration Agreement and/or the Corps of Engineers 404 permit process, as appropriate. Potential indtrect impacts shall be mitigated by providing a minimum 100-foot width buffer azea on either side of all alkali meadow habitat. No development or landscaping shall be allowed within the buffer areas. Impacts to alkali meadow from hydrological alterations (including potential displacement of native habitat with exotic and wetland species) shall be mitigated as described herein. The water runoff from surrounding development shall be diverted and controlled to retain the same amoun[ and seasonality of water input existing before development. A study shall be required at the SPA level of analysis to determine existing hydrological conditions of streams containing alkali meadow and what hydrological changes will occur to these streams after development. The results of these studies shall be used to engineer the storm drain system to reflect pre-impact hydrological conditions over the long-term. Vernal Pools. Mitigation for impacts to vernal pools includes preservation of 100 percent of lazge or high value vernal pool complexes and 998 percent preservation of all other vernal pools. The vernal pool complexes on Otay Ranch that are large or of high value and which require 100 percent preservation include J23-24, J25, J29-30, and J31+ on Otay Mesa: K1 and K15+ in Otay River Valley: M2 near Poggi Canyon: R1, R2, and R3 in Proctor Valley: K6 and K8 north of Lower Otay Reservoir: and K12 in the San Ysidro Parcel. The allowed 2 percent impact to any of the other vernal pool complexes shall be mitigated by restoration/enhancement of damaged vernal pool habitat within disturbed azeas of the preserved vernal pool complexes such that no net loss of vernal pool habitat value or azea occurs. Mitigation must be consistent with the requirements of Section 404 of the Clean Water Act. Restoration may include decompaction, sculpting and recontouring, and seeding of basins disturbed by dirt roads, trails, or scraped areas. Several such areas are available for restoration in the J23-24, J25, and J29-30 vernal pool complexes. Enhancement of vernal pools through removal of exotic plant species also may be an appropriate mitigation measure. Reintroduction of greatly declining vernal pool species to suitable areas for recolonization also should be considered. Vernal pool restoration/enhancement shall include afour-year experimental phase and an eight-year maintenance and monitoring period. Impacts to vernal pool habita[ will occur only after successful completion of the restoration program. Success criteria shall be based on established standards relative to undisturbed (i.e., least disturbed) vernal pools within the same vernal pool complex. Attributes to be used include water retention, percent cover of native vernal pool species, and diversity of native vernal pool and associated species. Restoration and enhancement methodologies shall be developed during 1108500/0 A-S the experimental phase and initially shall follow the strategies outlined in the RMP. Potential indirect impacts shall be mitigated by providing a minimum 100-foot width buffer area around the vernal pools, and their watershed. A lazger buffer azea and implementation of other measures e.g., fencing, educational signage, diversion of urban runoff, may be necessary to eliminate adverse effects of drainage, trampling, vehicles, dumping, and collecting and to provide sufficient resources to support appropriate pollinators and dispersal agents. Mitigation for impacts to southern interior cypress forest, coast live oak woodland, and southern live oak riparian forest and sycamore alluvial woodland shall include redesign to preserve 100 percent of these habitats. Potential indirect impacts shall be mitigated by providing a minimum 100-foot width buffer area around the sensitive habitat, within which no development or landscaping would be allowed. Impacts to these woodlands from hydrological alterations (including potential displacement of native woodland habitats with exotic and wetland species) shall be avoided. The storm drain system shall be engineered to best reflect the pre-impact hydrology for each of the woodland habitat types. Sensitive Plants. • Sensitive plant surveys to quantify acreage of occupied habitat and plant densities or population sizes for each SPA. • Project redesign to obtain the species-specific preservation standards. • Restoration or transplantation including a 2-4 year experimental phase and a 5-8 yeaz maintenance and monitoring period as appropriate for each species mitigation program. • Prevention of indirect impacts through provision of buffers, manipulation of hydrological conditions, and a fire management plan. • Provide buffers (i.e., set-backs from developed, landscaped, or other use areas) around the occupied and/or critical habitat (e.g., watershed for vemal pools, floodplain or drainage for willowy monardella) for all preserved populations. Buffers shall be of adequate size and configuration to eliminate adverse effects of trampling, vehicles, dumping, collecting, and adjacent construction, and, in conjunction with the preserved habitat, shall include sufficient resources to support appropriate pollinators. Buffer widths shall be a minimum of 50-100 feet for first, second, and third priority species and 25-100 feet for fourth priority species. Buffer widths shall be determined on aspecies-specific basis, and will be dependent on the sensitivity of the species, the susceptibility/tolerance of the species and/or its habitat to disturbance, and the adjacent land use. 1/08500!0 p_q For sensitive species occurring within seasonal streams, the water runoff from surrounding development shall be diverted and controlled to retain the same amount and seasonality of water input existing before development. A study to detemune existing hydrological conditions and a hydrological analysis of the streams within the proposed development that contain sensitive plant species shall be required at the SPA level of analysis. Species occurring in intermittent streams for which the above mitigation would apply include willowy monazdella, Otay manzanita, Orcutt's brodiaea, summer- holly, Tecate cypress, San Diego sagewort, Orcutt's bird-beak, San Diego marsh-elder, sptny rush, and potentially Campo clarkia, San Miguel savory, and Engelmann oak. A fire management plan shall be developed in accordance with the RMP to protect and appropriately manage populations of sensitive plant species. San Diego Thorn-mint (Acanthomintha ilicifolial. Redesign to preserve largest population (95% of species onsite), including watershed, any associated critical habitat, and a minimum of a 100-foot width buffer zone; and Introduce the species on appropriate soils on the ranch. Creation of artificial population shall involve see salvage of impacted population. Nursery propagation to increase seed; sowing of seed. A clay soil lens suitable for San Diego thorn-mint that is not presently occupied by this species must be used for the mitigation. If no such area is available, as determined by the plant ecologist and soil scientist during the experimental phase of the mitigation program, acquisition and long-term protection of an offsite population shall be required. San Diego Button-celery (Erynuium aristulatum vaz.oarishiil • Redesign to preserve 98% of species onsite; preserve 100% of species where occurring with other vernal pool indicator species; and • Vernal pool restoration and re-introduction of species into disturbed or historical vernal pools. Otay Tarweed (Hemizonia ortj~p~cL • Project redesign to include at least 80 percent of species in open space; and • Introduction of species in areas with appropriate soils, including seed salvage and nursery propagation to increase seed sowing. • Redesign of project to preserve at (east 80 percent of species onsite (preserve populations in northern Jamul Mountains); and • Propagation and re-establishment of any impacted plants to suitable slopes; would involve restoration of high elevation chaparral community. Oreutt's Brodiaea (Brodiaea orct!tt%%~. • Retain 75 percent of onsite population. 110850010 A-10 Regulation of water input to prevent significant indirect impacts from increased or decreased water flow from development; refer to buffer requirements and pre-impact hydrological studies and design of low-flow diversion system described above. Five-yeaz monitoring of intact population to: a) identify significant indirect impacts of development (e.g., trampling, dumping, hydrological alterations) and b) implement remedial measures (e.g., restoration, trash removal, repair fencing etc.).

Specific mitigation for all corridors shall follow detailed recommendations from the Otay Ranch Wildlife Corridor Study (Ogden 1992b). The following general recommendations apply to all regional and important local wildlife corridors. a. All wildlife corridors shall be retained as natural open space, contain native vegetation, and be used for only passive recreation. b. All road underpasses and bridges shall have natural vegetation underneath and be sufficiently wide to encourage wildlife use. c. Wildlife corridors through development shall be sufficiently wide to encompass the natural topography and allow undisturbed wildlife movement. 3. The following measures shall be implemented for the Otay River parcel: a. The potential California gnatcatcher and cactus wren corridor between Poggi and Wolf Canyons shall be restored to native coastal sage scrub vegetation. A natural open space easement through the northeastern comer of the landfill shall be secured. This easement would need to encompass the offsite portion of the corridor and any buffer zones recommended in the corridor study. b. Impacts from road construction to four other regional corridors in the Otay River pazcel shall be mitigated by road design and realignment following the Wildlife Comdor Study recommendations. - Otay Valley Road shall be fitted with a 12 foot drainage culvert at Wolf Canyon to allow bobcats to pass underneath. The Rock Mountain road crossing of the Wolf Canyon to Salt Creek gnatcatcher and wren corridor near the northwest end of the quarry shall follow recommendations of the corridor study. Residential development and the Otay Valley Road shall be moved north of the Otay River Valley to prevent impacts to the Wolf Canyon to Salt Creek corridor on the north slope of the valley. (This is also 1108500!0 A-23 recommended for reducing impacts to coastal cactus wren and California gnatcatcher habitat.) - Heritage Road, La Media Road, SR-125, and Alta Road shall be elevated at Otay River Valley crossings and along the north slope of the Otay River Valley following the Wildlife Corridor Study recommendations. Major ravines and drainages shall also be bridged to allow for movement of wildlife along the Otay River V alley. - The Salt Creek to Otay River Valley comdor would be impacted by Otay Valley Road/Hunte Pazkway on the western edge of Salt Creek. Any impacts to vegetation along this corridor shall be restored to coastal sage scmb or maritime succulent scrub as appropriate. The new Alta Road alignment crossing of Salt Creek shall be bridged to retain a corridor to the Otay River Valley. This alignment shall be shifted west out of O'Neal Canyon and west of the mouth of Salt Creek. If the existing Alta Road crossing of O'Neal Canyon is widened, it shall be fitted with a large underpass and bridges over major ravines to allow movement into the Otay River Valley. 4. The following measure shall be implemented in the Proctor Valley parcel: Corridor R1 (see Figure 3.3.-7 of Final Program EIR) - In the disjunct L-shaped parcel, low density development shall be pulled out of the ravine and well back on the ridge so that animals may access the ravine, which leads them northwest over the saddle and into the Sweetwater Reservoir. The corridor needs to be 1600 feet wide at the mouth of this ravine, with at least 500 feet of open space along the southwest side of the mouth of this ravine. b. In Proctor Valley, the corridor widens from 1300 feet at the northwest end to 2200 feet at the southeast end. LMV development east of Proctor Valley Road needs to be pulled back on the south side of the corridor. The K6 school may be within the buffer if the playing fields aze adjacent to the corridor, there is no lighting or activity at night, and appropriate fencing is maintained. Revegetation and screening from development is necessary in this portion of the corridor. The Proctor Valley Road crossing shall be bridged (see Wildlife Corridor Study). The comdor follows the deep canyon east of Proctor Valley and shall include rim to rim topography. It is approximately 1600 feet wide. Low density development extending into the canyon on the north side of the corridor shall be pulled back onto the ridgetops. Where delineation of rim to rim topography is not obvious there needs to be 800 feet of width in open space extending up each side of the ravine. d. To eliminate impacts by Proctor Valley Road to corridor 4, Proctor Valley Road shall be elevated across ravines along its alignment to allow for wildlife movement underneath and into the alternate comdor in the creekbed to the north of Proctor Valley Road. e. Corridor R2 -LMV, L, and MH development along the western site of this corridor needs to be pulled back to retain rim to rim topography in open !!08500!0 A-24 space. The corridor is approximately 1600 feet wide throughout the canyon. Low density development on a knoll on the east side of the corridor needs to be eliminated as it encroaches into the comdor. The proposed park at the south end of the corridor shall be designed at the SPA level so as not to impact the corridor, shall be sited within the buffer zone (moved east or west), and not be located within the ravine. The two Otay Lake Road crossings of this corridor shall be bridged as recommended in the Otay Ranch Wildlife Corridor Study. 5. The following measure shall be implemented in the San Ysidro parcel. a. To facilitate wildlife movement between the San Ysidro and Jamul Mountains, development which blocks or constrains corridors 2, 8, 10, and 11 shall be redesigned. b. Development and manufactured open space at the north end of corridor 8 in the San Ysidro parcel shall be eliminated from the canyon southeast of the San Diego Air Sports Center to retain a major local wildlife corridor. This is also recommended to retain high occupancy gnatcatcher habitat. (see footnote on page 18). c. At the SPA Level there shall be no new road alignments or development in natural open space and Special Resource Study Areas within Corridor 5. d. Development along the western portion of Little Cedar Canyon shall be pulled back to avoid constraining wildlife movement in corridors 10 and 11.
