NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of Chula Vista does hereby certify that EIR-89-3 has been prepared in accordance with CEQA and the environmental review procedures of the City of Chula Vista and that the City Council will consider the information in the Final EIR. BE IT FURTHER RESOLVED that the Salt Creek Ranch is subject to the following Mitigation Measures: 1. a. A buffer zone shall be between the project and EastLake Business Park to the south will provide visual and spatial separation between the residential area and empl ojnnent park land uses and will help to avoid adverse noise impacts. b. Techniques to accomplish this objective include variable setbacks and extensive landscaping within the buffer area. Specific measures shall be defined in the SPA Plan. c. Final design (SPA Plan, Site Plans) of the planning areas on the southern border of the site shall specifically address the land use interface. 2. Storm drainage and wastewater from residential areas in the Salt Creek Ranch development shall be collected in utility systems to be provided and diverted away from the reservoir (see Section 3.5, 3.6 and 3.13 of the EIR; plans to be approved by the City Engineering Department). Resolution No. 15871 Page 2 _ 3. Detailed design in the SPA Plan shall address the view condition from the reservoir to developed areas of the project site. Design shall incorporate specific techniques to mitigate view impacts, including site plan orientation, grading techniques, landscaping and architectural design. 4. The Salt Creek Drainage through the project site shall be retained in open space uses. Extensive planrings (approved by the City Parks & Recreation Department and City Landscape Architect prior to tentative map approval) within the drainage will occur and the existing stand of eucalyptus and pepper trees will be retained. The SPA Plan shall define in an Open Space Plan and Chapter guidelines for open space uses, buffer treatment, maintenance and natural resource management. 5. Land use compatibility impacts relative to use of the SDG&E easement as a trail can be mitigated by coordination with SDG&E during all phases of future planning. Such coordination will assure that proposed uses conform with SDG&E policy. The SPA Plan and PC Zoning regulations shall define permitted uses within the easen~nt, acceptable to the City and SDG&E. 6. Land use compatibility impacts relative to the Otay Water District ' reclamation facility shall be mitigated by implementing various design techniques to be identified in the project SPA Plan. Such techniques would include orientation of residential structures to minimize view of the facility, as well as the establishment of vegetative and spatial buffers between structures and the facility. 7. The project developers shall explore, in an affordable housing program, methods to devote at least 10 percent of the dwelling units to low and moderate income housing. The program shall be developed prior to or concurrent with the SPA Plan process, and shall be subject to City review and approval concurrent with the SPA Plan process or as otherwise acceptable to the City Planning Department. 8. Salt Creek shall be extensively planted as part of the project to recreate the environmental character of the area prior to agricultural use. As part of the SPA Plan process, an Open Space Plan and Landscape Plan and guidelines shall be created and approved by the City Parks and Recreation Department. 9. Urban design standards, further refined in the SPA Plan, shall reinforce the semi-rural ranch character of the con~nunity, with sensitivity to natural landform and use of landform grading along major transportation corridors and in high visibility areas. 10. Slopes of 25 percent or greater shall be preserved to the maximum extent feasible and acceptable to the City. Resolution No. 15871 - Page 3 ll. Introduction of manufactured slopes in areas designated as natural open space (with environmental sensitivity, as defined in Section/3.7) shall be prohibited, except where necessary to construct roads, trails or other public facilities, subject to the approval of the City Engineer and Director of Parks and Recreation. Such manufactured slopes will be revegetated with indigenous species as recommended by the project biologist. 12. During site design, emphasis shall be placed on mitigating views toward the development from the Chula Vista Greenbelt. Special attention to these relationships along the Salt Creek drainage on site will be provide. The SPA Plan shall identify guidelines and measures. 13. Conclusions and recommendations of the February 1988 and August/1988 GeoSoils reports, pages 23 through 42, and 24 through 39, respectively, shall be adhered to in accordance with City procedures, subject to approval of the City Engineer prior to any tentative map approvals. Recommendations therein cover the following topics, actions and potential impacts: ripping, soil removals, slope stability/grading, erosion control, sub-surface water control, earthwork grading and balancing, soil expansion, slope design, grading guidelines, foundation recommendations, retaining wall design, graded slope maintenance and planting, and procedures for grading plan review. 14. Upon preparation of detailed development plans (i.e., prior to SPA Plan or tentative map submittal), a registered civil engineer shall conduct a hydrologic and hydraulic analysis of the project. This analysis shall be conducted in accordance with City of Chula Vista guidelines and shall include but not be limited to sizing of on-site drainage facilities; design of energy dissipators at drain outlets; verification that downstream drainage facilities including natural channel s can accommodate any increase flow rate, and identification of improvements, i f necessary, to accommodate increased flows; verification of the adequacy of the Eastlake Business Centre storm drain; and evaluation of enhancements of natural drainage courses. 15. Drainage facilities and energy dissipators shall be constructed in accordance with the approved hydraulic analysis and shall be in place and functioning prior to completion of the grading operation. 16. The project shall be subject to review and approval by the State Department of Health Services (DHS). The project shall implement mitigation measures as set by DHS prior to the issuance of any grading permit. 17. Prior to or concurrent with SPA Plan approval, a diversion ditch ~a B shall be prepared and approved by the City of Chula Vista, City of San Diego, and DHS. The plan shall analyze the Resolution No. 15871 Page 4 -- possibility of sewage system failures; effects of increased levels of nutrients, salts and pesticides from landscaping and irrigations; and effects of petroleum products from surface runoff. Additional environmental analysis may be required based on the specific drainage ditch or other plans. Design of these plans shall also consider providing additional capacity for concurrent or future development. 18. The project proponent shall submit a erosion control plan prepared by a registered civil engineer in accordance with City of Chula Vista design standards. The plan shall be approved prior to issuance of grading permits and shall include placement of sandbags, temporary sediment basins, and an erosion control maintenance plan. lg. The project proponent shall submit a storm drain plan prepared by a registered civil engineer in accordance with City of Chula Vista design standards. The plan must be approved prior to the issuance of grading permits and shall include permanent erosion control facilities. 20. The most appropriate area for wetland habitat creation occurs in _ Salt Creek. Salt Creek exists at an elevation appropriate to support wetland habitats or could be graded down to an appropriate elevation with minimal soil displacement. This area would then be contiguous with existing wetlands, thereby enlarging and enhancing those areas. Approximately 1.4 acres of wetland habitat shall be created or enhanced on-site to mitigate for the loss of this acreage at a 2:1 ratio as a result of project implementation. Sufficient habitat exists on-site which would be suitable for wetland revegetation or enhancement techniques. A habitat plan shall be coordinated and negotiated prior to any SPA Plan approval. 21. Habitat replacement or enhancement mitigation measures which are finally agreed upon (prior to SPA Plan approval) shall be thoroughly evaluated and defined in a specific mitigation plan. This plan shall be approved by the resource agencies, and shall provide for short and long term monitoring and maintenance of the replacement habitat. The plan will also identify mitigation locations, and provide a more precise wetland habitat quality evaluation by the regulatory agencies, resulting in specific replacement or enhancement acreages, numbers and types of plant species to be used, and planting techniques. 22. Selective grading shall be required and enforced, i.e., only areas immediately subject to development should be graded. 23. Erosion prevention measures such as fences, hay bales, and/or detention basins shall be on-site during development and in place prior to construction. Resolution No. 15871 Page 5 24. Manufactured slopes and disturbed grassland in open space areas shall be revegetated with native scrub species found in the area. Revegetation of these areas would have the benefits of potentially providing habitat for the California gnatcatcher, increasing the quality of the riparian buffer in selected areas, and reducing the probability of non-native landscaping materials invading natural habitats. Species suitable for this revegetatton include the following: Artemisia california California Sagebrush Eriogonum fasciculatum Flat-topped Buckwheat Lotus scoparius Deerweed Salvia mellifera Black Sage Salvia apiana White Sage Haplopappus venetus Goldenbush Eschscholzia californica California Poppy Lupinus spp. Lupine 25. The coastal sage scrub revegetation areas shall be effectively hydroseeded, followed by a tackified straw mulch. Materials and seed mixes may be changed only with the approval of the project biologist/horticulturist. 26. This habitat shall be irrigated as needed for the first year to accelerate establishment and coverage. The hydroseeding shall be completed in the sunder, if possible, so as to establish cover prior to the rainy season. A number of annual species are included in the hydroseed mixture (California poppy and lupines) to provide color to the slopes. llqe species should reseed themselves yearly. 27. a. The Developer shall agree to participate in a regional or sub-regional multi-species coastal sage scrub conservation plan. If, prior to approval of the grading plan for areas lOa, lob, and ll (which are identified as the three easternmost "L" areas on Figure R-1 of the Final EIR), an off-site regional wildlife corridor linking San Miguel Mountain with the Upper Otay Reservoir has not been approved by the City as part of the conservation plan, then development of the 17 acre R-L development area in the eastern portion of the property shall not occur and a reconfiguration of the northeastern R-L area (as shown on Figure R-1 of the Final EIR) to provide a wider open space area for a regional wildlife corridor shall be implemented. The width of the open space area shall be sufficient to ensure long-term viability of the wildlife corridor (as shown on Figure R-l). This condition shall also be applied to conditions of the Tentative Subdivision Map. b. The GDP map shall be revised to delete development within a buffer area around the identified cactus wren nest site. Exclusion of this area from the development envelope has the effect of reducing the midpoint number of units from 2824 to 281 7. Resolution No. 15871 Page 6 - 28. Heavy equipment and construction activities shall be restricted to the grading areas to the greatest degree possible in order to reduce direct impacts to wetland habitat. Construction of cut and fill slopes, and equipment used for this construction, will be kept within the limits of grading. Prohibited activities in the wetland habitat include staging areas, equipment access, and disposal or temporary placement of excess fill. Construction limits and wetland habitat shall be flagged by a qualified biologist. Construction activities shall be monitored by an on-site inspector to ensure that grading activities do not affect additional acreage. Any unauthorized impacts cause by construction operations would require that the contractor replace all habitat to its original condition, with wetland habitat potentially being restored at greater that a 2:1 ratio. 29. Fueling of equipment shall not occur in any portion of the site near any intermittent stream or the water shed of the Otay Reservoir. 30. Areas designated as natural open space shall not be grubbed, cleared, or graded, but left in their natural state. 31. To ensure that contractors are fully aware of specific restrictions of the project, such as staging areas, limits of fill, no vehicle zones, and other appropriate regulations, information shall be clearly shown on the construction plans. Contractors shall be fully aware of the sensitivities and restrictions prior to bidding. 32. In the event that a fire or fuelbreak is deemed necessary, plant species used in this area shall be non-invasive, so as to reduce impacts to remaining native vegetation. Suitable species from a biological standpoint would be low growing, moderately fire/retardant, native species such as prostrate coyote bush (Baccharis pilularis var. pilularis). 33. Plants in riparian and/or natural areas within the project's boundaries shall not be trimmed or cleared for aesthetic purposes. 34. Revegetation of cut slopes external and/or adjacent to natural open space shall be accomplished with native plant species which presently occur on-site or are typical for the area. Suitable species include California sagebrush (Artemisia california), flat/top buckwheat (Eriogonum fasciculatum ssp. fasciculatum), black sage (Salvia mellifera), and San Diego sunflower (Viguiera laciniata). If this area is hydroseeded, measures shall be taken to ensure the exclusion of non-native, weedy species from the mixture. 35. Fencing shall be installed as feasible and acceptable to the City around the natural open space area to prevent adverse impacts to biological resources from domestic pets and human activity. An alternative would be the planting of barrier plant species that would discourage pedestrian activity into open space areas. Resolution No. 15871 - Page 7 Non-native species would not be acceptable as barrier plantings within open space areas. No active uses shall be planned in the open space easements, including building structures or construction of trails through this area unless approved by the City. 36. The City of Chula Vista shall assure the long-term conservation of remaining native habitat on-site (wetlands and uplands) by dedicating these areas as part of a natural open space easement. The City shall place an open space easement in this acreage which would eliminate future building activity and, in effect, set this area aside for the preservation of wildlife. Trails which would promote pedestrian activity in open space areas shall be carefully designed but when located at the expense of wildlife shall not be constructed. 37. Mitigation of impacts for important cultural resources will be achieved through either avoidance or by conducting a data recovery program. Avoidance could include capping sites with 2 feet of fill and incorporating sites into open space. 38. If avoidance of archaeological/historic resources cannot be achieved, a data recovery program to mitigate development impacts to important cultural resource sites (listed in Table 3-8 of the EIR) shall be conducted, including monitoring or, where necessary, surface collection and mapping of artifacts, and a phased data recovery program. Recommendations identified in Table 3-8 shall be utilized as the basic framework for the mitigation plan. This phased approach would employ a random sample in conjunction with a focused inventory for features (i.e., hearths, burials). The data recovery program shall be in accordance with a regional approach for all prehistoric sites within Salt Creek Ranch, Salt Creek I and EastLake III, thereby allowing a comprehensive understanding for these Early Period sites. This regional understanding would also be in agreement with the Bonita Miguel Archaeological District. 39. The data recovery program shall follow the Advisory Council's guidelines as defined within "Treatment of Archaeological Properties" A Handbook (ACHP 1980). The Treatment P1 an should be oriented to address local and regional research questions and clearly identify the methods to be used to address the research questions. Research questions to be addressed are listed on pages 5-6 and 5-7 of the June 1989 Salt Creek Ranch Cultural Resource Evaluation (ERC Environmental and Energy Services) on file at the City Planning Department. 40. Prior to issuance of a mass-grading permit the developer shall present a letter to the City of Chula Vista indicating that a qualified paleontologist has been retained to carry out resource mitigation. 41. A qualified paleontologist and archaeologist shall be at the pre-grade meeting to consult with the grading and excavation contractors. Resolution No. 15871 Page 8 42. A paleontological monitor shall be on-site at all times during the original cutting or previously undisturbed sediments of the Otay Formation to inspect cuts for contained fossils (the Otay Formation occurs generally above 680 feet elevation). The Sweetwater Formation shall be monitored on a half-time basis. Periodic inspections of cuts involving the Santiago Peak Volcanics shall be conducted in accordance with recommendations of the qualified paleontologist. 43. In the event that well-preserved fossils are discovered, the paleontologist (or paleontological monitor) shall be allowed to temporarily direct, divert, or halt grading to allow recovery of fossil remains in a timely manner. Because of the potential for the recovering of small fossil remains such as isolated mammal teeth, i t may be necessary to set up a screen-washing operation on the site. 44. Fossil remains collected during any salvage program shall be cleaned, sorted, and cataloged and then with the owner's permission, deposited in a scientific institution with paleontological collections such as the San Diego Natural History Museum. 45. East H Street through the project shall be designed to provide for the ultimate cross-section of 6-lanes west of Hunte Parkway and 4-lanes east of Hunte Parkway consistent with City of Chula Vista design criteria. Construction phasing shall be determined by the City in coordination with the ECVTPP. Future additional right-of-way along this roadway may be required, at the discretion of the City Traffic Engineer, due to future traffic volumes generated by the Otay Ranch project to the south and east. 46. The Circulation Element roadways of Hunte Parkway and Lane Avenue will require the following intersection lane configurations designed in accordance with the City's street design standards and/or as required by the City Traffic Engineer. Implementation/phasing shall occur (as directed by the City) to accommodate forecast buildout daily traffic volumes. 47. Specific project access and internal circulation plans (including bicycle, equestrian and pedestrian routes and crossings) shall be provided to the satisfaction of the City Traffic Engineer at the SPA Plan (general level) and Tentative Map (detailed level) stages of approval. 48. To fully mitigate project impacts onto local roads, the project shall participate towards off-site improvements on a fair share basis with other area developers consistent with development assumptions and network improvements within the adopted East Chula Vista Transportation Phasing Plan (ECVTPP). The Salt Creek Ranch project shall also comply with any additional requirements (i.e. road improvements or impact fees) defined in future revisions and Resolution No. 15871 Page 9 updates to the ECVTPP, as it pertains to the project's impacts onto the circulation system. Compliance shall be verified via review and approval of the SPA Plan and tentative maps by the City Traffic Engineer. 49. Potentially significant on-site exterior noise impacts due to vehicular traffic along particular noise-sensitive land uses proposed by the General Development Plan shall be mitigated by specific measures outlined in subsequent, site-specific noise analyses to be conducted at the SPA Plan level. It is anticipated that mitigation measures are anticipated to include use of walls and/or berms, adequate setback of lots and structures or a combination of methods. 50. Potentially significant interior noise impacts shall be mitigated through the reduction of exterior noise levels to below 60 dB(A) in residential areas (assuming the incorporation of standard building materials), or through the use of enhanced building materials (e.g., sound rated windows or insulation). A detailed site-specific acoustical analysis, to be conducted of the SPA Plan level, shall identify where this reduction is necessary and how it will be attained. Performance of effective mitigation will require reducing interior noise levels in single family units to 45 dB(A) CNEL or below. It is anticipated that mitigation measures will include the use exterior noise barriers and appropriate building materials. 51. The project, as proposed, incorporates traffic flow improvements (e.g., road construction), bus routes and bus stops at the SPA Plan and subsequent stages of planning. 52. Heavy duty construction equipment with modified combustion-fuel injection systems for emissions control shall be utilized during grading and construction. 53. Watering or other dust palliatives shall be used to reduce fugitive dust; emissions reductions of about 50 percent can be realized by implementation of these measures. 54. Disturbed areas shall be hydroseeded, landscaped, or developed as soon as possible and as directed by the City to reduce dust generation. 55. Trucks hauling fill material shall be properly covered. 56. A 20 mile-per-hour speed limit shall be enforced on unpaved surfaces. 57. Prior to issuance of bull ding permits, the project site shall either be annexed by OWD into Improvement District No. 22 or a new Improvement District shall be established for the project area. In addition, the project developer shall obtain written verification from OWD at each phase of development that the tract or parcel will be provided adequate water service (will-serve letter). Resolution No. 15871 Page 10 - 58. Prior to approval of any SPA Plan within Salt Creek Ranch, a Water Master Plan (and/or Agreement) shall be prepared and approved (by the City Engineer and OWD) for the Salt Creek Ranch development project. The Plan shall identify total and incremental water demand; specific facilities (size, location, etc.) including servicing in the 980 and 1296 Pressure Zones; implementation/phasing; and participation in the water allocation program and TSF financing program, encompassing this project and other projects in the OWD Master Plan service area. The Plan shall delineate at a more detailed level the recommendations of the April 1989 and October 1989 Wilson reports and July 1989 Graves report. 59. The use of reclaimed water is strongly encouraged and the project proponent shall make every attempt to develop such use. The project proponent shall, if feasible, negotiate an agreement with OWD to commit to the use of reclaimed water at the earliest possible date so that OWD can ensure that an adequate supply is available. If such an agreement is pursued, all documentation shall be subject to site-specific environmental analysis, and shall conform to the applicable regulations of the Regional Water Quality Control Board and the State Department of Heal th. 60. Water conservation measures for on-site landscaping and for maintenance of roadside vegetation shall be created and implemented by the project proponent, in coordination with the City Public Works Department the City's Landscape Architect and in consultation with OWD or other qualified water agency/organization. Conservation measures are recommended by the State Resources Agency Department of Water Resources (see Appendix A of the EIR), and include but are not limited to planting of drought tolerant vegetation and the use of irrigation systems which minimize runoff and evaporation loss. 61. The following water conservation measures should be provided; implementation shall be approved prior to issuance of certificates of use and occupancy; a) Low-flush toilets (Section 17921.3, Health and Safety Code). b) Low-flush showers and faucets (California Administrative Code, Title 24, Par 6, Article l, T20-1406F). c) Insulation of hot water lines in water recirculating systems (California Energy Commission). 62. Prior to approval of any SPA Plan within Salt Creek Ranch, a Wastewater Master Plan and/or Agreement for the project shall be . prepared by the proponent and approved by the City Engineer. The Plan shall identify total and incremental wastewater generation, specific facilities required, funding and implementation/phasing in relation to this project and other associated project's phasing in the area. The Plan shall confirm that the entire project can be sewered to the Telegraph Canyon Trunk Sewer, shall further detail Resolution No. 15871 Page ll the April 1989 Wilson report, and shall be coordinated with and/or conform to the City's Public Works Facility Plan,. when complete. (Note that sewer upgrades, including effects on downstream facilities, will be required wherever the sewer exceeds the design capacity). 63. Prior to SPA Plan approval, the project proponent shall provide documentation confirming elementary school site locations and CVCSD approval of school locations on Salt Creek Ranch. This approval shall entail site location, size and configuration of schools, with provisions for access and pedestrian safety to the satisfaction of CVCSD. Funding shall also be addressed and confirmed in accordance with CVCSD procedures. 64. The project SPA Plan shall further define the boundaries, acreage and manner of open space preservation (e.g. dedicated open space; preservation easements) on the Salt Creek Ranch property in a form and manner acceptable to the City Parks and Recreation Department and Planning Department. 65. The project applicant shall reserve solar access and implement passive solar systems. 66. The project applicant shall install energy efficient appliances in residential developments. 66. The project applicant shall limit strict lighting and install energy efficient lights. 67. The project applicant shall use appropriate building design, orientation, landscaping and materials to maximize passive solar heating and cooling, and construct energy-efficient structures.
