Nessel, Senior Planner Prepared by= P&D Technologies, Inc. 401 West "A" Street suite 2500 San Diego, California 92101 (619) 232-4466 (Job #10134.00) May 1990 " " Resolution No. 90-095 Page 5 INTRODUCTION Recent California legislation (AB 3180) requires the adoption of a mitigation or reporting program in conjunction with approval of projects for which a Negative Declaration or Final EIR was prepared and mitigation measures were recommended in' connection with significant impacts. The purpose of the law is to establish a reporting or monitoring program to assure implementation of recommended mitigation measures. The following monitoring program is recommended as part of the Old Coach Golf Estates EIR (May 1990). The EIR discusses the development of approximately 708-acres located north of the intersection of Espola Road and Old Coach Road in the northeastern portion of the City of Poway. The applicant, Environmental Development, Ltd., proposes to develop the site with a mixture of uses including a 27-hole golf course with clubhouse, and a maximum of 164 single-family residential units. The proposed Old Coach Golf Estates project would involve development other than that allowed under the existing General Plan and zoning designations. A general plan amendment (GPA) and zone change (ZC) to Planned Community (PC) designation would be required for this project. In addition to the project, five alternatives are analyzed. These include the "No Project" alternative, the implementation of the General Plan land use/zoning designation, the Reduced Density Alternative, the Environmentally Sensitive Alternative and the Alternative Site evaluation. The following text is divided into issue areas analyzed in the EIR. Each issue contains three sections: recommended mitigation measures, mitigation monitoring and reporting program and the level of significance after mitigation section. Resolution No. 90-095 Page 6 L~ND USE AND PLANNING CONSIDERATIONS RECOMMENDED MITIGATION MEASURES Plan-to-Plan Impacts to land use would be less than significant at the plan-to- plan level, and no mitigation would be necessary. Plan-to-Ground At the plan-to-ground level of analysis, the following elements of the Old Coach Golf Estates Specific Plan satisfy the intent of the General Plan and are considered mitigation: o provision of common open space lots including the mini- park and trail system preservation of the majority of the riparian and oak woodland corridor o contour grading for pads and sensitive grading for roads and golf course development flag lots to minimize grading for access roads retention of native vegetation in open space easements provision of multi-level foundations in areas with natural slopes greater than 25 percent other mitigation measures contained in this Draft EIR would be made conditions of approval of the project and ~ ~" Resolution No. 90-095 Page 7 would serve to reduce identified potential impacts to a level below significance at the plan-to-ground level. Plan-to-Adjacent Development Ail efforts should be made to ensure that the project is as low- scale and visually unobtrusive as possible to maintain land use compatibility with the surrounding area. The Specific Plan text for the Old Coach Golf Estates Planned Community contains a Community Design Element which provides overall design concepts and guidelines for the future development of the site. The concepts and guidelines would regulate project development to assure compatibility with surrounding land uses, and to create an aesthetically pleasing community. These guidelines address streetscape, entry points, street identification~ equestrian and pedestrian trails, lighting and architectural style. The architectural guidelines address site design principals, grading, lot layout, building materials, roofing, walls and fences. In addition to a Homeowners Association which would be formed to maintain in-common landscaping and amenities, an Architectural Review Committee would be established to implement the guidelines of the Specific Plan text. In reviewing each residential site plan, the Architectural Review Committee would consider such criteria as: O O O O Site topography and protection of steep slopes View orientation and view protection Access to the proposed residence Natural site amenities such as rock outcroppings, trees and natural drainage channels The Architectural Review Committee would also review the site plans for the residences, the clubhouse and any other associated buildings. Implementation of the guidelinJs contained in the Resolution No. 90-095 Page 8 Specific Plan would serve to minimize potential land use conflicts between the surrounding homeowners and on-site uses. MITIGATION MONITORING AND REPORTING PROGRAM To assure compliance with the guidelines of the Specific Plan for the Old Coach Golf Estates Planned Community, all buildings must receive approval from the Architectural Review Committee. In addition, all structures and associated land uses must be approved by the city of Poway prior to the issuance of a Building Permit. LEVEL OF SIGNIFICANCE AFTER MITIGATION Plan-to-Plan The development of 164 residential units on minimum one acre lots is proposed within the project site. Recreational uses such as the mini-park, 27-hole golf course, and related clubhouse facility would be subject to conditional use permit approval under the current rural residential designations. However, the site is within the Old Coach Special Study Area and these types of uses are anticipated within the General Plan. Because the proposed uses are consistent with the special study area of the General Plan and because a planned community zone with a companion specific development plan is proposed to implement the study area, impacts to land use are considered less than significant at the plan-to- plan level. Plan-to-Ground The General Plan contains numerous policies concerning rural residential development in hillside areas and preservation of sensitive environmental resources. The proposed project incorporates numerous special features which would substantially Resolution No. 90-095 Page 9 address and implement the intent of these General Plan policies. The proposed Specific Development Plan contains a Community Design Element which details implementation of site-specific design guidelines in response to the goals of the General Plan. The plan retains a significant portion of sensitive habitat and also substantially preserves the natural topography of the site. The proposed tentative map includes preliminary grading within residential lots. The limits of the area of disturbance are confined to rural local roads, and the pad areas for future home sites and associated cut/fill slopes. The preliminary grading design for residential lots substantially conforms to the natural land contours. All grading associated with the project will conform to the provisions within the specific plan and will adhere to the City's Grading Ordinance and General Plan policies which will mitigate potentially significant impacts to a level below significance. Plan-to-Adjacent Development The site is adjacent to surrounding residential development on the west, south, and southeast. The proposed project would be consistent with surrounding development. With mitigation to ensure careful site design, lot layout, and architectural review, compatibility with surrounding land uses would be achieved. No significant impacts to land use would occur at the plan-to-adjacent development level. Resolution No. 90-095 Page 10 VISUAL QUALITY/LANDFORM ALTERATION RECOMMENDED MITIGATION MEASURES Landform Alteration Since grading plans for the golf course were not available, the impacts of the landform alteration created by the golf course could not be analyzed. Before the golf course grading permit is approved, the applicant would be required to submit a final grading plan for the City's review and approval. Since individual lot owners may require additional grading to fit a particular home design and appurtenant features on the lot, approval of grading and building permits for residential lots would be conditioned on the City's review of the plans. The tentative map proposes 31 residential lots to be located in areas with slopes greater than 25 percent. The proposed project design should include multi-level foundations in these areas which would require less grading and allow for substantial preservation of the natural landform and vegetation. Public Viewshed The proposed project includes a view approximately 75 feet along Espola Road. conformance with City requirements for officially designated scenic roadways. setback easement of This easement is in developments along Since no visual quality impacts have been identified in association with the viewshed of the adjacent residential viewers, no mitigation measures are recommended. ' , ' Resolution No. 90-095 · Page 11 MITIGATION MONITORING AND REPORTING PROGRAM To ensure that on-site grading is in compliance with preliminary grading plans as designated in the tentative map, the City Engineer will monitor grading by conducting a physical Snspection of the site before, during, and after grading. LEVEL OF SIGNIFICANCE AFTER MITIGATION The proposed project is substantially in confo£mance with the provisions of the General Plan with the minor exception of the placement of residential lots on prominent ridgeline and hillside features. The loss of these features is considered adverse but not significant because the project proposes dedication of permanent, natural open space of 126 acres of the back portions of residential lots. The major portion of this open space is comprised of slopes greater than 25 percent. The use of flag lots, contour grading, and rounding of manufactured slopes in the project design would also reduce the visual quality impacts of the project. Additionally, with the incorporation of multi-level foundations in the project design, visual quality impacts associated with the development on slopes greater than 25 percent would be at a level below significance. The visual quality impact of the Old Coach Golf Estates project on the public viewshed along the scenic corridor of Espola Road would be at a level below significance because of the provision of natural, open space, contour grading, and distance from the scenic roadway. Resolution No. 90-095 Page 1 2 BIOLOGY RECOMMENDED MITIGATION MEASURES The proposed project would preserve approximately 226 acres of coastal sage scrub habitat in natural open space areas. Preservation areas include Lot C, a portion of Lot E, natural undisturbed areas of the golf course, and the rear portions of residential lots. With the preservation of 226 acres, impacts to coastal sage scrub habitat would be reduced. An additional 25 acres of dedicated open space consisting of coastal sage scrub would be required to mitigate the biological resource impacts to a level below significance. The applicant has agreed to prepare a revised tentative map which would incorporate additional acreage for dedicated open space on the project site. - To mitigate impacts to coastal sage scrub to below a level of significance, either on-site mitigation, off-site mitigation, or a combination of both on-site and off-site mitigation could be implemented. On-site mitigation would require the redesign of the project and the designation of an additional 25 acres of open space (beyond the approximately 226 acres already being preserved) to create a minimum of 250 total acres of contiguous open space. Another option would involve off-site mitigation in the form of habitat preservation or restoration. This would require the acquisition of 25 acres of coastal sage scrub habitat off-site. The third mitigation option would involve a combination of both on- site and off-site preservation or restoration of coastal sage scrub habitat. A minimum of 25 contiguous acres of this habitat would need to be preserved. The above mitigation measures would involve either the preservation of 25 acres on-site and/or the acquisition of a 25 acre off-site mitigation site. The applicant has agreed to implement one of the above mitigation options which will reduce potential impacts to coastal sage scrub habitat to below a level of significance. · Resolution No, 90-095 Page 13 Mitigation measures to reduce the impacts to other sensitive biological resources to below a level of significance will include: Riparian Habitat Permanently preserve the entire riparian forest corridor through the property as a dedicated biological open space easement. This easement would protect a significant population of the San Diego sagewart, along with a large number of mature sycamore, cottonwood, and willow trees that provide valuable habitat for raptors and other riparian birds including habitat for the federally endangered least Bell's vireo. Provide a buffer of no less than 100 feet where feasible, from the edge of the riparian forest canopy dripline as a part of the easement to protect the wetland and provide a transition zone to residential areas or golf course areas. The entire length of this buffer will be staked in the field by a qualified biologist. Temporary chain- link fencing will be placed at the outer edge of the buffer to prevent encroachment into the wetland by grading vehicles. In areas where less than 100 feet of undisturbed buffer is necessitated, given constraints of topography and engineering design, an appropriate buffer should be defined in the field by a qualified biologist. In no case should this buffer be less than 50 feet from the outermost edge of the canopy dripline. The proposed widening of Old Coach Road will be designed to avoid impacts to the wetland areas designated on the biological habitats map (refer to Figure 4-9), where possible. A dedicated biological open space easement will be placed on the riparian habitat along Sycamore · Resolution No. 90-095 Page 14 Creek and Thompson Creek to minimize impacts to riparian habitat associated with road widening. To ensure that encroachment into the riparian area does not occur, the wetland habitat will be staked in the field by a qualified biologist and clearly marked. The realignment of the road may be required in the south portion of the project to avoid impacts to riparian. By realigning the road to the west of its current alignment, so that the roadway centerline would follow the property's eastern property line, impacts to riparian habitat can be reduced. This realignment may require the redesign of fairway #20 and the reconfiquration of Lot C. Additional environmental review of the grading plan for the realigned road would be required to assess impacts to riparian habitat. If the alternative alignment affects any riparian habitat, the applicant will provide mitigation in the form of enhancement and/or revegetation of riparian habitat. This may include on-site mitigation, off-site mitigation (along the portion of Sycamore Creek that is adjacent to the eastern property boundary) or a combination of both on-site and off-site mitigation. Riparian habitat will be replaced at a 3:1 ratio such that there would be no net loss of habitat. The final designs of the sewer system and golf course will be coordinated to consider the feasibility of placing the golf cart crossings for riparian habitat within the sewer crossings to lessen impacts. The least impactive route for the golf cart paths and sewer crossings will be staked in the field by a qualified biologist. Before these areas could be cleared of vegetation, the City will approve the crossings. Once staked and approved, a construction easement will be fenced to avoid impacts beyond the construction corridor. 10 # · Resolution No. 90-095 Page 15 Any riparian habitat affected within the construction corridor (approximately 0.4 to 0.6 acres) will be replaced at a 3:1 ratio such that there would be no net loss of habitat quality. Southern Oak Woodland Habitat Permanently preserve southern oak woodland habitat in the proposed dedicated biological open space easement for this site. A biological buffer of no less than 25 feet from the outer edge of the canopy dripline will be included as a part of this easement. No grading activities or storage of equipment or vehicles will occur within this buffer to minimize the chances for direct tree loss through root damage. The entire length of the buffer should be staked in the field by a qualified biologist. Temporary chain- link fencing will be placed at the outer edge of the buffer to prevent encroachment into the oak woodland by grading vehicles during the construction phase of development. 1:1 replacement for loss of oak trees in accordance with the City of Poway tree replacement ordinance Diegan Coastal Sage Scrub Permanently protect a minimum of approximately 50 percent of this habitat in a dedicated biological open space easement (250 acres). This includes 215 acres to be preserved entirely, and 11 areas of cut fill slopes to be revegetated with a native seed mixture as part of a Diegan Coastal Sage Scrub Habitat Restoration Plan 11 Resolution No. 90-095 Page 16 prepared for this site. Such a revegetation plan will be developed by a qualified biologist working in concert with a revegetation specialist and/or landscape architect as a condition of tentative map approval, and will detail planting regimes, schedules, seed m%xture, irrigator details, and other features to ensure a successful revegetation effort. The approximately 11.5 acres to be revegetated will be added to the biological open space easement. Protection of five areas supporting the largest stands of the Palmer's ericameria by placement in the dedicated biological open space easements. To fully mitigate for the loss of other~extant specimens of Palmer's ericameria, seeds from specimens slated for destruction would be collected for reseeding purposes. The seed will be collected before grading and used in the hydroseed mixture as a section of the Diegan Coastal Sage Scrub Habitat Restoration Plan. The propagation of containerized specimen of this rare species for slope plantings may be also required. This would be detezmined as a part of the Diegan Coastal Sage Scrub Habitat Restoration Plan. A spring survey of the Diegan Coastal Sage Scrub will be performed to search for signs of the state-listed slender-pod jewelflower. If present, appropriate mitigation would include on-site protection, transplan- tation, and/or other appropriate measures. 12 Resolution No. 90-095 Page 1 7 Southern California Grassland Habitat Construction areas for golf cart paths will follow the least impactive route. Golf cart paths will be developed in a sensitive manner (i.e., grading e.quipment will move single-file from one fairway to the next along proposed golf cart paths. Any area disturbed beyond the eight foot wide paved golf cart path will be revegetated with coastal sage scrub habitat. Perform a spring survey during a year of normal rainfall to determine the presence of San Diego thornmint, Orcutt's brodiaea, California adder's-tongue fern, and other very sensitive herbs within the Southern California grassland habitat. Mitigation measures recommended as a result of the spring survey for these sensitive resources will be implemented. This will reduce impacts to below a level of significance. California Gnatcatchers Impacts to the substantial population of California gnatcatchers present on this site could be fully mitigated through a combination of on-site preservation (through biological open space preservation), and off- site compensation. The recommended off-site compensation plan will involve the preparation and implementation of a focused California Gnatcatcher Resource Study. This study will result in the generation of critically-needed information and allow substantially better planning with respect to this rapidly declining species in the future. 13 Resolution No. 90-095 Page 18 Under such a plan, the applicant will work with the City of Poway to establish a fund specifically created for the purpose of inventorying and assessing the status of this resource within the City's sphere of influence. In addition, the applicant will fund a Part-time biologist/ planner for a minimum of one year to develop and implement the study. It is expected, given an anticipated scope-of-work, that contractual field study and possibly contractual report preparation would be required. In this case, the planner would monitor the efficiency of such efforts. Tasks directly associated with such a plan include: (a) precise mapping of all areas of extant Diegan coastal sage scrub within the City of Poway using low altitude aerial photographs and brief field verification; (b) contacting local biologists familiar with this species to generate an initial data base; (c) conducting focused field reconnaissance surveys of all areas of appropriate habitat; (d) the preparation of a gnatcatcher distribution map and accompanying technical report identifying areas of high-quality habitat and large areas of contiguous habitat; and (e) the identification areas suitable for preservation, habitat restoration, and/or potential mitigation within the study area. Poway lacks a comprehensive study such as this, and the gnatcatcher distribution maps and report would allow development in the City to be directed in a biologically sensitive manner with respect to this resource. The results of this study could also be incor- porated into the City's updated General Plan. 14 Resolution No. 90-095 Page 19 MITIGATION MONITORING AND REPORTING PROGRAM The city of Poway's Planning Services Department will approve the applicant's retention of a qualified biologist to perform the following mitigation monitoring and reporting.tasks. At the completion of each of these tasks, the biologist will provide a letter report to the City to confirm that each of the mitigation monitoring measures were completed. Specifically, the approved biologist will stake the limits of the riparian oak woodland and Palmer's ericameria (including a 25 foot buffer from the edge of the oak woodland and an approximate 100 foot buffer beyond the canopy of the dripline of the riparian forest, as detailed in the Mitigation Section of this report). The limits of these areas would be surveyed in the field and plotted on the final map. The City will ensure that this area is shown within a-biological open space easement on the final map. The final map will show the tentative location of exception areas for up to four golf cart crossings and up to four sewer crossings of the riparian. A biologist will stake the least impactive route for the golf cart paths and sewer crossings in the field. Before these areas could be cleared of vegetation, the city will approve the placement of the golf cart path and sewer crossings. Once staked and approved, a construction easement will be fenced to avoid impacts beyond the construction corridor. A biologist will monitor the clearing of vegetation, which will be done by hand. The approved biologist will work in concert with a revegetation specialist and/or landscape architect to develop two separate habitat restoration plans; a Diegan Coastal Sage Scrub Habitat Restoration Plan and a Riparian/Oak Habitat Restoration Plan, both specific to this site. The plans will be submitted to the City and other agencies, if appropriate, for'review and approval. 15 · Resolution No. 90-095 Page 20 These plans will detail planting regimes, schedules, hydroseed mixtures, irrigation details, and other features to insure successful revegetation effort and full mitigation for lost habitat. The approved biologist will attend the pre-grading meeting with the construction supervisor and the grading contractor to inform them of the location of the biological open space easement and to confirm that no grading or ground disturbing activities are allowed within the biological open space easement. The approved biologist will review the grading plans for Old Coach Road to ensure that grading does not encroach into the riparian area. If it is determined that there would be potential impacts to wetlands, then additional environmental review will be required to assess impacts. Any mitigation measures recommended as a result of this review will be incorporated as conditions of approval of the final map. The approved biologist will collect and prepare seed of Palmer's ericameria from the site in the appropriate season to be used in the hydroseed mixture as a part of the Diegan Coastal Sage Scrub Habitat Restoration Plan. The applicant may be required to contract the propagation of containerized specimen of Palmer's ericameria for slope plantings, if specified in the habitat restoration plan. A biologist will collect and distribute the seed of the Palmer's ericameria in the appropriate season. 16 Resolution No. 90-095 Page 21 The approved biologist will perform a spring survey for the slender-pod jewelflower within the coastal sage scrub habitat and for the San Diego thornmint, Orcutt's brodiaea, California adder's-tongue fern, and other very sensitive herbs within the grasslan~ habitat. These species will be mapped and impacts will be quantified in a survey report. Mitigation measures contained within the survey report will be made conditions of approval of the final map. The City and the applicant will work together to ensure that a adequate fund is established to allow the implementation of a focused California Gnatcatcher Resource Study. In addition, the applicant will fund a part-time biologist/planner for a minimum of one year to develop and initiate the study. The City will ensure that this study is developed and initiated in a timely fashion not to exceed one year from approval of the Tentative Map. The applicant will provide a breakdown of the acreage to be preserved in biological open space easement for both the riparian/oak woodland and coastal sage scrub habitat. The City Department of Planning Services and a qualified biologist will confirm that the acreages are adequate prior to approval of the final grading plan, final map, and the issuance of grading permits. LEVEL OF SIGNIFICANCE AFTER MITIGATION Development of the Old Coach Golf Estates project as proposed would result in potentially significant impacts to sensitive biological resources. Mitigation measures agreed to by the applicant will be incorporated as conditions of approval of 'the tentative map. Recommended mitigation measures will reduce all identified impacts to below a level of significance. 17 Resolution No. 90-095 Page 22 TRANSPORTATION RECOMMENDED MITIGATION MEASURES Traffic impacts associated with the proposed Old Coach Golf Estates project will be partially mitigated through project design. Old Coach Road will be improved to collector arterial standards from the intersection of Espola Road north to the entrance of the proposed clubhouse. The portion of Old Coach Road to be designated as a private road will be improved to the appropriate non-dedicated rural local roadway standard. When the threshold of 850 ADT is reached at the Espola Road/Old Coach Road intersection, the City will ensure that a detailed signal warrant evaluation is performed to confirm the need for signalization. The applicant will provide a traffic signal at the Old Coach Road/Espola Road intersection when it is needed. These improvements will reduce project impacts on Old Coach Road to below a level of significance. Espola Road (west of Old Coach Road) is currently exceeding LOS "E" volumes. Project impacts to this segment of Espola Road will be partially mitigated by the proposed "half width" improvements. The westbound portion of this segment will operate within LOS "C" capacity; however, the proposed project will contribute to existing congestion on the single lane eastbound portion of this segment. Improvements are specified in the General Plan to bring this roadway segment up to four-lane major arterial standards. According to the City of Poway Engineering Department, these improvements are not included in Poway's 1990 budget. Also, buildout volumes (25-27,000) currently projected for Espola Road east of Old Coach will exceed secondary arterial LOS "C" capacity (20,000), as well as LOS "E" capacity (25,000). The City of Poway may investigate reclassification of this road segment. The developer will work with the City of Poway to ensure that half- width improvements are consistent with ultimate standards for 18 Resolution No. 90-095 Page 23 Espola Road, and to determine the timing of future improvements to the eastbound segment of Espola Road in relation to project timing. The proposed project should be staged such that development is keyed to these improvements to Espola Road. Improvements are needed to mitigate the regional cumulative impacts to existing and projected LOS at the intersection of Rancho Bernardo Road with Pomerado Road. Dual left-turn lanes are recommended for the southbound approach of Pomerado Road and for the eastbound approach of Rancho Bernardo Road. This intersection is located within the City of San Diego. Therefore, discussions between the cities of Poway and San Diego may be appropriate to ensure that these mitigation measures are mutually satisfactory. The applicant will work with the City to determine a fair share contribution toward these improvements. MITIGATION MONITORING AND REPORTING PROGRAM The improvement of Old Coach Road to collector arterial standards, the "half" width improvement of Espola Road (along the property boundary), and the signalization of the Old Coach Road/Espola Road intersection will be made conditions of approval of the tentative map. The City Engineering Department will ensure that improvements are in place prior to building permit issuance for the residential lots. LEVEL OF SIGNIFICANCE AFTER MITIGATION Using the daily traffic volumes projected for the road segments, and comparing them to the criteria from the projected daily traffic volumes using Level of Service C, the analysis concludes that when project generated traffic is added to General Plan buildout traffic volumes, significant circulation impacts would occur. When all mitigation measures are in place, most roadway'segments and all key 19 Resolution No. 90-095 Page 24 intersections in the project vicinity are expected to operate at acceptable levels of service (LOS D or better). The General Plan classification of Espola Road as a major arterial west of Old Coach Road and as a secondary arterial east of Old Coach Road will not provide adequate capacity for LOS "C" operation given current projected buildout forecast volumes. Given this, the City of Poway may investigate reclassification of these facilities. NOISE RECOMMENDED MITIGATION MEASURES The project noise impact study indicates no significant noise impacts from project-related traffic on local receivers. However, given the importance placed on an acceptable noise environment in the Poway region, and the possibility of impacts to units in the northern half, there are a number of noise constraints that should be considered as mitigation for the project-related incremental noise impact. These constraints include: Ail construction and general maintenance activities, except in an emergency, would be limited the hours of 7:00 am to 7:00 pm and would utilize the quietest equipment available. The operation of any machine which produces a noise level greater than 100 dB within 50 feet of the observer would be prohibited or shielded. In conjunction with the City review of and approval for construction of structures on lots 1, 89, 88, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 149, 150, 152, 155, 156, 157, and 164, the 60 dB noise contour shall be shown on all site plans for these residential 16ts, and appropriate 20 Resolution No. 90-095 Page 25 conditions for noise attenuation measures shall be added, if necessary, to the application approval document(s). If the set-back is not sufficient to assure that the structure would be outside of the 60 dB contour, then alternate measures to assure an interior noise level of 45 dB would be necessary. These include architectural design and construction techniques as outlined in Policies 4.c and 4.d of the General Plan Noise Element or acoustical barriers such as walls and barriers. MITIGATION MONITORING AND REPORTING Ail grading plans shall contain the statement "Ail grading, construction and maintenance activities shall be limited to the hours of 7:00 am to 7:00 pm." The hours of operation will be enforced by the on-site construction supervisor. The on-site construction engineer shall conduct periodic, not less than bi-weekly, testing of noise levels adjacent to major machinery. Any machine producing noise in excess of 100 dB within 50 feet will be removed and replaced with a quieter machine. The requirement for interior and exterior noise attenuation on lots 1, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 149, 150, 152, 155, 156, 157, and 164 must be stated on the CC&Rs for the planned community subdivision map. Prior to .approval of site plans and building permits for these lots, the noise attenuation measures and building inspection must be verified by City planning and building inspection staff, and completed prior to occupancy Of the residential structures on these lots. 21 Resolution No. 90-095 Page 26 LEVEL OF SIGNIFICANCE AFTER MITIGATION The proposed project would generate noise in the project area during construction and along area roadways from additional traffic associated with the project. Noise levels during construction would represent a less than significant impact as activity would be limited to reasonable hours and excessively noisy machines would be prohibited. Traffic noise would result in minimal impacts to major roads near the project as the noise has been anticipated in the General Plan and these roads contain adequate setbacks. Traffic on Old Coach Road would be minimal and the 60 dB contour would be less than 70 feet from roadway centerline. The building pads of several lots (1, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 149, 150, 152, 155, 156, 157, and 164) are less than 56 feet from Old Coach Road. There is a possibility that noise levels would exceed the 60 dB exterior standard or 45 dB interior standard, resulting in adverse impacts to structures. While this possibility is considered slight, particularly in the northern half where traffic would be reduced by diversion, future site specific noise assessment would be necessary on these lots to verify that setbacks are adequate. If setbacks are not adequate, alternate measures would be necessary to assure acceptable interior noise levels. This would reduce impacts to less than significant levels. AIR QUALITY RECOMMENDED MITIGATION MEASURES Development of the site with 164 residential units as proposed by the project would be consistent with the existing regional growth forecasts for the City of Poway and as such has been considered and incorporated into the local air quality emissions control plan (SIP revisions). No significant impacts would be associated with the residential component of the project and' no mitigation is 22 Resolution No. 90-095 Page 27 necessary. The golf course and clubhouse recreational facilities were not assumed in the regional growth forecast. By definition any additional trips generated by a project not included in the SIP revisions is considered adverse; however, the air quality impacts qenerated by this project were considered small, .and as such, less than significant. No mitigation measures are necessary. Residential and recreational land uses such as those proposed for the project potentially affect air quality almost exclusively through the increased automotive emissions. Any single development usually does not cause clean air standards to be violated, but the cumulative effect of all such sources ultimately leads to unhealthful air quality throughout the air basin. The most important impact mitigation measure is that any reasonably available transportation control measures (TCMS) must be implemented where possible, especially those that concentrate on reduction of short, inefficient trips. While such measures are only minimally effective for a project such as the Old Coach Golf Estates development because all site activities are dependent upon automobile access, the adoption and implementation of TCMS nevertheless recognizes the need to reduce air pollutants where possible. In addition to a general commitment to incorporate TCMS where possible to reduce regional vehicular Emissions/Impacts, there are several measures which should be followed during construction to reduce construction impacts to air quality. Use of dust control techniques during grading to minimize fugitive dust. These include cleaning, sweeping, and sprinkling with water, or other means as necessary. 23 Resolution No. 90-095 Page 28 Routing construction vehicles to prevent queuing near pollution sensitive receptors (i.e., near residences as they are constructed). MITIGATION MONITORING AND REPORTING During construction, the on-site superintendent must monitor the dust control measures and should report weekly (verbal reports are acceptable) to the City Engineering staff. LEVEL OF SIGNIFICANCE AFTER MITIGATION On a regional scale, it is not the total emissions that are significant, but rather whether the project has been properly anticipated within SANDAG's air quality planning'framework. The residential component of the proposed project has been anticipated within regional air quality plans. Impacts to air quality associated with this component are considered less than significant. However, the clubhouse and golf course recreational components were not incorporated into the regional air quality plans (as they were not specified in the City of Poway General Plan); however, project-generated impacts are considered less than significant. No mitigation measures are necessary. CULTURAL RESOURCES RECOMMENDED MITIGATION MEASURES The resources within the Old Coach Golf Estates project which would be adversely affected by development include sites SDi-ll,518H, SDi-807, SDi-ll,516, SDi-ll,521, SDi-11,522, and SDi-11,523. The mitigation measures proposed for the prehistoric sites are generally the same, varying only in scope as the sizes of the sites vary. In general, all project grading should be monitored by an 24 Resolution No. 90-095 Page 29 archaeologist to ensure that any sites which might contain significant deposits or artifacts which were not identified during the evaluation phase can be recovered or analyzed prior to the removal of the site. To mitigate direct impacts to the five prehistoric sites (SDi-807, SDi-ll,516, SDi-521, SDi-11,522, and SDi-11,523), one of two basic mitigation alternatives may be selected individually for each site. The first type of mitigation measure is preservation, through project redesign with legally delineated open space easements providing protection to the sensitive archaeological sites. The second type of mitigation measure would involve a data recovery program to salvage a sufficient quantity of data to fully tap the research potential of the sites. The details of these alternatives are provided below. The project could be redesigned and all or a portion of the sites could be preserved within open space easements. The decision regarding which resources would be placed within easements would be made on a site-by-site basis. The easements would be designed on the basis of the portions of the sites which retain sensitive materials or features and the location of significant deposits. Easements would also include buffers of 30 feet to ensure that any accidental encroachment into the easements would not directly affect the sites. The approximate configurations of the easements which would be required for Sites SDi-807, SDi-ll,521, SDi-11,522, SDi-11,523, SDi-ll,516 are provided in the Technique Appendix on file at the City. The configurations are approximate, and the exact delineation of the easements would be determined after consultation between the City, applicant, and qualified archaeologist. At that time, the easements would be mapped in concert with the project engineers, and would be staked in the field to be surveyed precisely by the certified surveyors. Any easements for archaeological sites must be either fenced or extensively staked during construction to prevent brushing or disturbance to the sites by construction crew~ who might otherwise 25 Resolution No. 90-095 Page 30 be unaware of the presence of significant archaeological sites. The easements must be recorded legal instruments attached to the prospective lot deeds. The easements must carry the stipulations that no vegetation or artifacts can be removed from within the easements, that the easements cannot be landscaped, that no excavation can be conducted within the easements, that no livestock of any type can be kept within the easements, and that it is the responsibility of the owner of any lot which includes any part of an archaeological easement to protect that site from disturbance by others. Site SDi-11,522, must retain the rock enclosures at the south end of the site in an easement regardless of the elements of the project redesign. These may actually fall within the easement for the biological habitat along Sycamore Creek. Since, these rock enclosures are considered sensitive resources, they must be placed in an easement designated specifically for archaeology and must be fenced to prevent unnecessary site visitation. The rock walls are very susceptible to disturbance by persons simply walking near or over the walls. The mitigation of impacts to the remainder of SDi- 11,522 can be accomplished through data recovery or preservation. Data Recovery The mitigation of impacts through data recovery can be accomplished by implementing a program outlining a research design for each individual site. The details of each research design will not be discussed here; however, the research design for each site would include a series of research questions or objectives pertinent to the types of data already identified within the site, and an excavation design based on a statistically derived random sample of between 2 percent and 5 percent of the volume of the midden area. The completion of a random sample may be followed by further excavations directed toward the study of s~ecific features or 26 Resolution No. 90-095 Page 31 deposits discovered during the sampling program. The field study will be followed by detailed laboratory analysis of the recovered material, special studies such as radiocarbon dating and obsidian hydration, and appropriate research. All of the data and discussions pertaining to the investigations at each site would be presented in a report of findings. Upon acceptance of the reports, the site or sites could be graded as part of the development. The level of effort needed for data recovery at the sites will be based upon the size of the midden deposit, the density of the artifact content, and the percentage of the midden to be sampled. The historic site, SDi-ll,518H, will require a different approach to mitigate impacts. At the present time, the site is located in the area proposed for the construction of a lake and the eighteenth fairway of the golf course. If the golf course is not redesigned to preserve the historic site, then an extensive data recovery program would be necessary. Three alternatives are presented as potential mitigation measures for the site: Preservation, with the entire site area preserved, combined with an excavation program to gather additional data before the site is preserved. The site would be included within an easement and the foundation secured and covered with dirt. Preservation, with the reconstruction of the adobe structure, an excavation program to gather additional information about the adobe, and the incorporation of the site into the golf course design, with no easement but a set of restrictions regarding the use and maintenance of the adobe. Data recovery, through a program of field investigation in which the total area within t~e foundation and a 27 Resolution No. 90-095 Page 32 sizable area immediately around the adobe is excavated and examined. The intent of this program would be to recover a sufficient level of information to address the research questions posed in the research design, to remove sections of the foundation for preservation, and to conduct historic research so that the grading of the site, or its inundation by the proposed lake, would not constitute an adverse impact. The technical report contains detailed guidelines for implementa- tion of only one of these mitigation alternatives. MITIGATION MONITORING AND REPORTING PROGRAM Prior to approval of the grading plan, measures to mitigate signif- icant impacts to archaeological resources must be completed in full. This will include the development of a research design cov- ering the exact mitigation program to be implemented at each site. Any open space easements to be employed as mitigation must be le- gally attached to the final tentative map, and the consulting arch- aeologist must review the map for accuracy prior to approval by the City. A report of the mitigation program must be filed with the City of Poway, and approved prior to the initiation of grading. Upon the completion of the conditions of mitigation, and the commencement of development, an archaeologist must be on-site for the initial brushing and the first grading of the site (not necessarily the entire period of grading of the site (not necessarily the entire period of grading and recompaction). The monitoring archaeologist must meet with the grading contractors and field supervisors prior to any site activities involving machinery to delineate any areas which must be avoided. The archaeologist will monitor the grading of the project and will have the authority to stop or redirect grading should any archaeological materials or 28 Resolution No. 90-095 Page 33 deposits be discovered which were masked during the archaeological survey. Any newly discovered sites would be required to be evaluated and a determination of significance made. If measures are needed to mitigate impacts from the continuation of grading, these must be completed prior to the grading of the area of the site. LEVEL OF SIGNIFICANCE AFTER MITIGATION The project contains several archaeological sites, six of which have been evaluated as unique resources under the criteria for unique sites set forth in CEQA. Impacts to these sites would be significant. The adverse impacts could be mitigated though a program of either preservation or data recovery. Successful completion of a mitigation program would reduce impacts to below a level of significance. SOILS/GEOLOGY RECOMMENDED MITIGATION MEASURES A geotechnical analysis will be prepared to provide detailed information regarding potential constraints and to define site specific remedial measures. All remedial measures to address expansive soils will be recommended by a registered engineer as part of this study (to be completed prior to approval of the grading plans). This analysis will also include detailed subsurface soils borings. In general, colluvial soils will require removal and recompaction, and clay soils will require replacement with non-expansive granular materials. Blasting to remove granitic rock will be necessary to prepare the site for construction. To minimize any potential damage associated with the remote possibility of groundshaking, all structures'must be constructed 29 Resolution No. 90-095 Page 34 in conformance with the Poway Grading Ordinance and Unifo£m Building Code. MITIGATION MONITORING AND REPORTING Prior to approval of the grading plan, the soils and geology analysis must be completed. Any recommended measures would be incorporated as conditions on the final map. The City Engineer will review the soils and geology analysis and recommended measures for adequacy. The City Engineer must verify that all structures are in conformance with the Uniform Building Code. LEVEL OF SIGNIFICANCE AFTER MITIGATION The site contains several soils and geologic constraints to future development including non-rippable granitic rock, alluvium and near-surface groundwater. The proposed residential building pads and the clubhouse site substantially avoid the alluvial soils with the exception of minor portions of six lots. Proposed development would overlay granitic rock which would require blasting to prepare the site for development. With remedial action, soil and geological impacts would be reduced to a level below significance. HYDROLOGY/DRAINAGE/WATER QUALITY RECOM}{ENDED MITIGATION MEASURES Standard erosion techniques as specified by the Engineering Department of the City of Poway will be employed to reduce erosion and siltation of Sycamore Creek. These include but are not limited to hydroseeding all slopes and pads after grading and limiting all 30 Resolution No. 90-095 Page 35 hillsides to 2:1 slopes. Energy dissipators will be provided at all drainage discharge points to control erosion. To reduce impacts of increased siltation to a level below significance, the provision of desiltation basins and/or detention basins may be used to control runoff quality and quantity. It is feasible to construct desiltation basins to remove suspended solids from urban runoff, while the detention basin functions to minimize flooding. Ultimate design and maintenance will be determined by the City Engineers. In accordance with the recommendations contained in the HEC 2 study, further detailed drainage studies will need to be completed with more accurate topography to clarify the velocities at stations 3, 25 and 26. Additional cross-sections will be evaluated downstream of Sections 3-6, 14, 15, 17, 20, 21, and 27 to accurately determine conveyance change. A detailed study will also be made of discharge into existing swales and drainage courses leading into Sycamore Creek. To minimize the amount of contaminants that would potentially enter the surface and groundwater system, the golf course will be constructed and operated to reduce surface runoff and prevent infiltration. Portions of the golf course will be designed to carry surface runoff to centralized collection points where the drainage will be intercepted by an underground pipe system. Energy dissipators will be provided at all drainage discharge points to control erosion. To minimize over-fertilization of the golf course and subsequent leaching of fertilizers into the groundwater, pesticides will be selected with regard to their soil absorption, low water solubility, and rapid degradation. To minimize the amount of fertilizer released into the environment, soil tests will be made periodically to determine the exact amount of micro- nutrients, phosphorous, and potassium that ne~d to be applied. 31 Resolution No. 90-095 Page 36 MITIGATION MONITORING AND REPORTING PROGRAM The 2:1 slope and hydroseeding requirements will be written as conditions of approval on the Tentative Tract Map and verified by the City Engineer. All other standard erosion control techniques will be specified on the tentative map and made conditions of approval. These will also be verified as acceptable by the City Engineer prior to grading. Hydrological studies will be completed for each drainage basin. Grading and improvement plans completed for the final map in the Specific Plan area will include drainage facilities based on hydrological studies and engineered in accordance with the design standards of the City of Poway. Discharge velocity from each drainage basin will need to be reduced in order to decrease the amount of transported material. Energy dissipators will be provided at all drainage discharge points and must reduce discharge to non-erosive levels (i.e., six feet per second). Prior to final map approval, the City will ensure that the developer submits verification that an adequate drainage system has been provided. The applicant will conduct soil testing periodically, not less than once per month, to provide for more exact applications of fertilizers. The results of the soil testing will be submitted to the City Engineering Department. Adjustments to the fertilizer application program will be the responsibility of the applicant. LEVEL OF SIGNIFICANCE AFTER MITIGATION The construction of roads, rooftops, and driveways would increase the amount of impervious surface on the site which would increase surface runoff. The area devoted to the golf course would result 32 Resolution No. 90-095 Page 37 in some increased surface runoff and possible infiltration due to irrigation. The points of concentration may also be altered when drainage is channelled into Sycamore Creek. Overall, the change in runoff patterns would be minimal and as such, is not considered significant. Golf Course maintenance would result in the use of pesticides, herbicides, and fertilizers. Compliance with the Safe Drinking Water and Toxic Enforcement Act of 1986 and careful management techniques, including soil monitoring, would minimize the impacts to groundwater and surface water to below a level of significance. The proposed development would not involve the placement of structures within the 100-year floodplain, except for the widening of Old Coach Road, and is substantially in conformance with the policies and intent of the General Plan. UTILITIES AND PUBLIC SERVICES RECOMMENDED MITIGATION MEASURES Schools Potentially significant impacts to the school system as a result of the proposed project will be partially mitigated by the construction of new schools in the area. These schools will be in place prior to project buildout. In addition, provision of developer fees, (in accordance with Governmnet Code 53080 and Poway Unified School District Resolution 32-90), would serve to fully mitigate potential impacts to the school system. Developers fees, which are on an inflationary scale, are currently set at $1.58 per square foot of residential 33 Resolution No. 90-095 Page 38 development, and $.26 per square foot of connnercial and industrial developments. Water Service Based on the City's current water allocation of 24 mgd and the City's average usage of 12.5 mgd, there would be an adequate water supply available to serve the project site as well as other approved developments such as the South Poway Project. Additionally, all residential construction will be required to install water conserving appliances and facilities such as low volume toilets, showers, washing machines etc., and by using primarily drought-tolerant landscaping, state-of-the-art irrigation methods, and dual piping for the use of reclaimed water in the future. The provision of the above measures would be ensured through the City's Development Review process. The actual time of availability of reclaimed water is uncertain at this time as facilities to serve the site have not been identified. Project specific infrastructure such as distribution lines and pumping stations would need to be constructed throughout the majority of the site to service the proposed project. Funding for the provision of these water facilities would be the responsibility of the developer. The City of Poway and the developer would be required to negotiate with the CWA to ensure that the use of raw water from the aqueduct is acceptable until a reclaimed water source becomes available. Sewer Service A detailed sewer study must be provided to quantify the impacts that this project and other approved projects in the area would have on the existing sewer system. Assuming that City Council will provide a Service Availability letter for the'entire project, the 34 Resolution No. 90-095 Page 39 following alternative mitigation measures are recommended. The first measure would entail connecting the project site with the existing eight inch sewer main adjacent to the site on St. Andrews Drive (with ultimate delivery to the Metro system). Based on the detailed sewer study, a determination needs to be made whether this line and associated systems would need to be upgraded or not. Another alternative would be to connect to the Escondido sewer main which is located to the northwest, approximately one mile from the project site. However, this system is currently at capacity and would require upgrading and expansion of sewer mains and pump stations prior to project approval. If the City Council only provides Service Availability for a portion of the project, then the project should be developed in phases such that the number of units constructed (and/or the clubhouse) is consistent with the amount of sewer capacity allocated. MITIGATION REPORTING AND MONITORING PROGRAM Schools A building permit will not be issued until the State mandated school fees have been paid by the applicant. The proponent must present written proof of payment to the City prior to issuance of building permits. Water Service The use of water conserving facilities, drought-tolerant land- scaping, and dual piping for future reclaimed water use will be ensured through the City's Development Review process and will be made conditions of the Resolution of Approval of the tentative map. An agreement must be obtained between ali affected agencies 35 Resolution No. 90-095 Page 40 concerning the use of raw water from the aqueduct for golf course irrigation purposes. Sewer Service Prior to approval of the tentative map, a Statement of Sewer Availability will be issued for the project. The City will ensure that the project is phased in accordance with the amount of sewer capacity allocated to the project. The City Engineering Department will ensure that a detailed sewer study is a condition of approval of the tentative map and that any recommendations contained in the sewer study are implemented. LEVEL OF SIGNIFICANCE AFTER MITIGATION Schools New schools are expected to be in place in the project area before the project is developed. This will create enough capacity in the Poway schools to accommodate the students generated from the project. In addition, developers fees will be paid in accordance with state legislation. The project impact on the school system will be below a level of significance. Water Service The maximum water consumption projected for the project is approximately 659,800 gd. This consumption would require 2.8 percent of the City's available water supply. This would not constitute a significant impact by itself. However, due to the relative scarcity of local water in Southern California, any new development will add incrementally to a cumulatively adverse effect that is only partially mitigated through water conservation measures. 36 .... Resolution No. 90-095 Page 41 Sewer Service It is uncertain whether or not City Council will provide a Statement of Sewer Availability for the entire project or only a portion of it. When combined with impacts from other approved development in the area, project impacts on the City's sewer system (and the Metro system) are potentially significant. This is due to the rapid growth of San Diego County and the corresponding demand on the existing sewer system, specific on-site and off-site impacts and mitigation measures cannot be quantified until a detailed sewer feasibility study is completed. RECREATION FACILITIES RECOMMENDED MITIGATION MEASURES Ail trails will be developed in accordance with standards of the Trails Element of the General Plan. the trails MITIGATION MONITORING AND REPORTING PROGRAM Developer will dedicate land and/or pay fees to mitigate impacts to recreation facilities in conformance with the General Plan and Chapter 16.38 of the Poway Municipal Code. The Poway Planning and Community Services departments will verify that trail construction is in conformance with the standards of the Trails Element. This will be made a condition of approval of the project. Prior to approval of any implementing maps the applicant will dedicate land, or pay fees in lieu of land dedication, to fulfill the City requirements for impacts to recreation. This would be made a condition of the Resolution of Approval of the tentative map. 37 Resolution No. 90-095 Page 42 LEVEL OF SIGNIFICANCE AFTER MITIGATION The proposed project would result in development of a 27-hole golf course, a mini-park, and several pedestrian and equestrian trails. The golf course would be available for public play in the initial stages of development and would represent an increase in available recreation facilities; however, the golf course area would not qualify for park dedication. To mitigate the potential impacts of increased population on recreation facilities, the applicant will be required to dedicate land or pay impact fees. This would reduce potential impacts to below a level of significance. The proposed trail system would be consistent with the Trails Element of the Poway General Plan, the proposed trail system of the county of San Diego, and would complement the San Dieguito River Valley Regional Open Space Park. No significant impacts are associated with the trails component of the project. POPULaTION/GROWTH INDUCEMENT RECOMMENDED MITIGATION MEASURES The project would incrementally affect population and growth inducement in Poway. As no significant impacts have been identified in relation to population and growth inducement from the development, no mitigation is necessary. MITIGATION MONITORING AND REPORTING PROGRAM No mitigation monitoring and reporting program is needed as no mitigation is required. 38 Resolution No. 90-095 Page 43 LEVEL OF SIGNIFICANCE AFTER MITIGATION The proposed project would not induce growth by itself as a minimum of jobs would be created (50-100) and any impacts associated with the project would be cumulative, potentially significant. Development of the site would increase the population in Poway (525 persons); however, this increase is not considered significant in itself. Again, these impacts would contribute to cumulative, potentially significant impacts to the city of Poway. This project is in conformance with the policies of the General Plan as specified in the Planned Community Development Plan. In other words, the increases in population and employment in this area have been anticipated by the General Plan. Thus, growth would result from development of the site, but other than an incremental and unquantified, indirect demand for housing as a result of new employment opportunities and a slight increase in population (one percent of Poway's total population), the project would not induce new growth. Therefore, no mitigation would be required. SOCIO-ECONOMIC FACTORS RECOMMENDED MITIGATION MEASURES No significant impacts have been identified with the development of this project; therefore, no mitigation measures are required. MITIGATION MONITORING AND REPORTING PROGRAM No mitigation has been recommended; as a result, monitoring and reporting program is necessary. no mitigation 39 Resolution No. 90-095 Page 44 LEVEL OF SIGNIFICANCE AFTER MITIGATION The projected increase in population and housing would not have a significant impact on the City's housing stock and population, especially if the project is built in increments. For example, if the project is built over a period from two to six years, annual population increases would represent about 0.5% of the City's population, which would not be a significant impact. However, if the project is not implemented in phases, potentially significant impacts could occur. If the project reaches buildout in a year, the population increase generated by the project would be 2.8 percent of Poway's total population. An increase of this size may not pose a significant impact because the growth pattern would be relatively definitive in that the project is not expected to induce growth (Section 4.12). Employment increases associated with the proposed golf course would benefit the City's economic base on a small scale, and would not directly impact the City adversely. HEALTH, SAFETY AND NUISANCE FACTORS RECOMMENDED MITIGATION MEASURES Fire Protection Response times in the areas north of the gated entrance would be significant. Homes in these areas will be required to install residential fire sprinkler systems. Adequate water capacity and pressure will be provided in addition to the improvements to Old Coach Road and all other project streets which will facilitate fire protection service. Significant impacts resulting from the potential for brush fires can be mitigated to a level below significance with the implementation of the m~asures requirements 40 Resolution No. 90-095 Page 45 contained within the adopted "City of Poway Guide to Landscape Requirements" (November, 1988) Fire Control (Section IV). These requirements include planting and maintenance programs necessary for fire control plans. Fire control plans for five linear fire protection zones located between the residential structure up to 210 feet distance from the structure. Provisions within the City's landscape requirements 'will mitigate impacts to a level below significance. The tentative map shall be conditioned to meet the approval of the City Fire Marshal. The emergency medical service response time will be reduced to less than five minutes by the establishment of an additional paramedic unit at Fire Station 2. This additional unit would serve the site as well as the surrounding vicinity. In the interim, service would be provided by the existing paramedic unit located at Station 1. The project proponent will be assessed a fair share portion of the cost for this new paramedic unit, based on a fee structure established by the City. Law Enforcement Impacts to Sheriff's Department at the project level are not considered significant, and no mitigation measures are required. Dam Failure Potential inundation risks will be placed on the deeds of sale of lots 60, 61, 62, 63, 64, 65, 79, 80, 81, 82, 83, 84, 85, 86, 87, 144, and 157. The risk of inundation will also be stated in the project CC&R document. These lots (or portions of them) will only experience flooding under the worst case s~enario. As stated 41 Resolution No. 90-095 Page 46 above, this is a highly unlikely occurrence. Under the more probable breached failure scenario, it is uncertain whether or not these lots would experience any flooding impacts because they are located on the outer fringe of the inundation area. Even if flood waters reached these lots, it is anticipated that impacts would not be significant. Therefore, providing interested buyers of these lots with information related to the potential flooding hazards is considered acceptable mitigation. With this information, potential impacts are considered to be mitigated to below a level of significance. Hazardous Waste No known hazardous sites exist on the property; therefore, no mitigation is required. MITIGATION MONITORING A/~D REPORTING PROGRAM Fire Protection The City's Fire Marshal shall approve any proposed fire access roads, structures, and landscaping design required to reduce service impacts to below a level of significance. Prior to approval of the final map, a funding agreement must be reached between the applicant and the City to mitigate impacts to emergency medical services. Law Enforcement No mitigation program is required at the project level; therefore, no mitigation monitoring is required. 42 Resolution No. 90-095 Page 47 Dam Failure Prior to recordation of the final map, the applicant will provide the City with a letter from the California Department of Real Estate confirming the fact that the "white paper" which accompanies every deed of sale will include a statement informing affected buyers of the potential safety hazard associated with dam failure. The City shall ensure that appropriate language concerning dam failure is included in the project CC&Rs. LEVEL OF SIGNIFICANCE AFTER MITIGATION Development of the site with a golf course and 164 residential units would result in potentially significant impacts related to fire protection, emergency medical (paramedic) services, and flooding hazards associated with the potential failure of either the Ramona or Poway dams. There would be no potential significant impacts related to hazardous waste. Impacts to emergency medical service will be reduced to below a level of significance by the provision of fair share funding for a new paramedic unit. Informing interested buyers of the lots which have a potential flooding hazard from dam failure is considered acceptable mitigation to reduce impacts to below a level of significance. ENERGY AND SCARCE RESOURCES RECOMMENDED MITIGATION MEASURES Enerqy Because the increased demand for energy is not considered a significant impact, mitigation is not required. However, the guidelines for energy efficient residential development in the 43 Resolution No. 90-095 Page 48 General Plan will be incorporated into the Specific Development Plan. Water The increased demand for water resulting from p~oject implementa- tion is not considered a significant impact. However, to minimize cumulatively significant regional impacts the following conserva- tion policies of the General Plan will be incorporated into the tentative tract map and the Specific Plan and thereby into project design. These include: installation of water conservance appliances and facilities usage of primarily drought-tolerant plants and shrubs in landscaping use of state-of-the-art water-conserving landscape irrigation systems in common green areas installation of dual piping for the use of reclaimed water to irrigate the golf course and all public and private landscaping MITIGATION MONITORING AND REPORTING The City and the Architectural Review Committee as established by the Specific Plan must review all proposed residential units, golf course and clubhouse, and all project landscaping for compliance with the energy and water conservation measures outlined in the General Plan and all other applicable City regulations and ordinances including Chapter 13.10 of the Municipal Code (included in Appendix J). In addition, adherence to the City's landscaping 44 ~'"~"~ Resolution No. 90-095 Page 49 and irrigation standards and guidelines shall be made a condition of approval of the tentative map and included in the Specific Plan. Applicable policies/guidelines of the State Water Resources Board, RWQCD, and CWA would also be adhered to. LEVEL OF SIGNIFICANCE AFTER MITIGATION The increased demand for energy and water is not regarded as a significant impact as supply is currentlY available. Water supply in southern California is particularly sensitive to statewide drought conditions. Project-related impacts to water resources, in conjunction with other regional development, may be regarded as cumulatively significant. The applicant will provide an appropriate distribution system for future use of reclaimed water distribution system for the project as required by the City of Poway. 45 Resolution No. 90-095 Page 50 CANDIDATE FINDINGS FOR THE OLD COACH GOLF ESTATES FINAL EIR ..The following findings are made relative to the conclusions of the Final Environmental Impact Report (EIR) for the Old Coach Golf Estates project. The project involves the development of 708 acres of vacant land consisting of uses to include a maximum of 156 single-family residential units, a 27-hole golf course with a club house facility, driving range, putting green, local/regional trail system, and a three-acre mini-park, and open space. The project analyzed in the Draft EIR included 164 single-family residential lots of (1) one acre minimum. During the DEIR public review period, the applicant revised the project design which now proposes a maximum of 156 residential lots all of which observe a (1) one acre minimum lot size. In addition, the project application includes a General Plan Amendment (GPA 90-0lA) and companion zone change (ZC 90-0lA), Planned Community Specific Plan (SP 89-01), and a Tentative Tract Map (TIM 89-13). These findings are made pursuant to Section 21081 of the California Public Resources Code and Sections 15091 and 15092 of the California Administrative Code. FINDINGS A. The City of Poway, as lead agency and decision maker, having reviewed and considered the information contained in the Final EIR for the project and the public record, finds, pursuant to CEQA and CEQA State Guidelines, that changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR with respect to the areas of (1) land use and planning, (2) visual quality/landform alteration, (3) biology, (4) transportation/circulation, (5) noise, (6) air quality, (7) cultural resources/archaeology, (8) soils/geology, (9) hydrology/drainage/water quality, (10) utilities and public services, (11) recreation facilities, (12) population/growth inducement, (13) socio-economic factors, (14) health, safety, and nuisance factors, and (15) energy and scarce resources. Specifically, the City of Poway makes the following findings with respect to the identified significant environmental effects of the project: With respect to land use and planning considerations, (DEIR, pg. 4-1) the proposed project involves a General Plan amendment and a zone change from RR-A, RR-B, and RR-C, to Planned Community (PC). Measures have been incorporated into the project which will reduce land use impacts to below a level of significance. Impacts and mitigation were evaluated at three levels: Plan-to-Plan, Plan-to-Ground, and Plan-to-Adjacent Development. Resolution No. 90-095 Page 51 Plan-to-Plan Because the proposed user"are consistent with the Old Coach Special Study .Area of the General Plan and because a planned community zone with a companion specific development plan is proposed to ensure consistency of the General Plan and zoning for the project impacts to land use are considered less than significant at the plan- to-plan level. Plan-to-Ground no Provision of substantial and viable amounts of open space, a mini- park for service-recreations and a trail system which complements the City and Regional adopted trail plans. bo Contour grading for Residential lot pads and sensitive grading for roads and golf course development. c. Flag lots to minimize grading for pads and access roads. Provision of multi-level foundations in areas with natural slopes between 25 percent and 45 percent. eo Preservation of riparian habitat along Sycamore and Thompson creeks as a dedicated open space easement, and an irrevocable offer of dedication to the City for open space easements over portions of lots 4, 26-35, 45-52, 55-63, 71, 78, 79, 81-88, 91, 93-99, 104-107, 111-120, 122-126, 132-136, and 147-152. All grading associated with the project will conform to the provisions within the specific plan and will adhere to the City's Grading Ordinance, General Plan policies, and applicable sections of the Poway Municipal Code. Plan-to-Adjacent Development An Architectural Review Committee will be established to review each individual site plan for view orientation and protection, of views from existing homes adjacent to the project, protection of steep slopes, access to the proposed residence, and protection of natural site amenities (e.g., trees, natural drainages,, and rock outcroppings). Adherence to the Old Coach Golf Estates Specific Plan Community Design Element which provides overall design concepts and guidelines for future development. o o Resolution No. 90-095 Page 52 With respect to visual quali~/landform alteration (DEIR, pg. 4-20) the proposed project is in substanti.al confos'mance with the provisions of the General Plan Community Design, Community Character Element and the Land Resource Conservation Element with the exception of the placement of residential lots on prominent ridgeline and hillside features and development in areas greater than 25% slope. The loss of these features is, however, considered an adverse rather .than a significant impact as 126 acres within the residential (primarily consisting o.f slopes greater than 25 percent) lots will be placed into natural open space. Measures which have been incorporated into ihe project design and would reduce impacts to visual quality/landform alteration to below a level of significance include: no The use of flag lots, contour grading, rounding of manufactured slopes and the incorporation of multi-level foundations on slopes between 25 and 45 percent. Co do eo Development and/or grading within areas of 45 percent and above natural slope will be prohibited, except where it is unavoidable in order to permit reasonable street access to a development area. The City will review grading and landscaping/irrigation plans for individual home sites as part of the Development Review and Minor Development Review application process to ensure that they are in substantial conformance with the City's Landscape Guidelines and Standards, final grading plan, and final map. The City Engineer will monitor grading by conducting a physical inspection of the site before, during, and after grading. A final grading plan for the golf course must be prepared and approved by the City of Poway's Director of Planning and Engineering Services. A view set-back easement of 50 feet minimum width along Espola Road has been incorporated into the design. Only minor grading by individual lot owners may occur beyond the residential pad prepared by the de,~eloper and such minor grading shall strictly observe and not impact environmentally sensitive open space areas. With respect to biology, (DEIR, pg. 4-37), mitigation measures have been identified which would reduce significant biological impacts to a level less than significant. These include the following: ao bo co do f. Resolution No. 90-095 Page 53 Preservation of a minimum of approximately one half of the Diegan coastal sage (250 acres) §crub habitat in a dedicated biological open space easement. This consists of approximately 69.2 acres in the golf course, 35.9 acres in Lot "A", 2.6 acres in Lot "C", 9.1 acres in Lot "E" (th'is excludes the 3.1 acre mini-park) and approximately 2.7 acres of Lot "F". In addition, approximately 111 acres would be contained in the rear portions of residential lots and would be protected by. means of an open space easement in which no ground disturbing activities would be allowed. An additional 19.4 acres of coastal sage will be preserved either on-site, acquired off-site, or a combination of both on-site and off-site preservation. Permanently preserve the entire riparian woodland and wetland habitat corridor for Sycamore and Thompson creeks in a dedicated biological open space easement. Future grading plans for the golf cart path/sewer crossings, golf course, and Old Coach Road, will be subject to subsequent environmental review. If impacts to riparian habitat cannot be avoided, then appropriate mitigation would be a condition of approval of the grading plans. Riparian habitat will be replaced at a 3:1 ratio such that there would be no net loss of in- kind habitat. Provision of a buffer of no less than 100 feet where feasible, from the riparian canopy dripline, and in no case shall the buffer be less than 50 feet from the outermost edge of the dripline. Staking and temporary chain link fencing will reduce potential impacts from grading equipment. If feasible, align the sewer and golf cart crossings of riparian habitat in the same alignment and easement area. The alignment will be oriented to result in the least impacts to biological resources and will be staked by a biologist and fenced to prevent additional impacts. Riparian habitat lost will be replaced at a 3:1 ratio to ensure no net loss of in-kind habitat. Design Old Coach Road to minimize impacts to riparian habitat, where possible. To ensure that further disturbance does not occur, wetlands will be staked by a biologist. Future grading plans will be subject to subsequent environmental, review. If impacts to riparian habitat cannot be avoided, then appropriate mitigation will be required as a condition of the grading plan.and improvement plans. Riparian habitat will be replaced at a 3:1 ratio such that there would be no net loss of in-kind habitat. Permanently preserve southern oak woodland habitat in a biological open space easement. Incorporation of a biological buffer of no less than 25 feet from the outer edge of the dripline within the_biological Resolution No. 90-095 Page 54 open space easement. Staking of the buffer by a biologist and fencing to prevent encroachment during construction will be required. Grading plans for the golf cart path and sewer line crossings, golf cours~e! and Old Coach Road will be reviewed by the biologist and the C~ty. If impacts cannot be avoided, then mitigation will be required as a condition of the grading plans and improvement plans. Oak woodland habitat will be replaced at a 3:1 ratio such that there · would be no net loss of in-kind habitat. go Replacement for loss of isolated mature oak trees (outside of the oak woodland corridor) at a 1:1 ratio in accordance with the City's ordinance. ho Perform a spring survey(s) to detect potential, state-listed endangered plants and sensitive plants within the southern California grassland and the Diegan coastal sage scrub habitats. Recommendations for mitigation measures will be made as part of this study. Implementation of the mitigation measures recommended as a result of the spring survey(s) will be a condition of approval of the Tentative Map require project compliance with the Certified final EIR. Prepare a Diegan Coastal Sage Scrub Habitat Restoration Plan for the project site. Mitigate impacts to the sensitive California gnatcatcher via on and/or off-site mitigation. On-site mitigation could include dedication of open space, while off-site could include acquisition of off-site open space or contributions to establish a fund for a comprehensive gnatcatcher study within the City's Sphere of Influence. The preservation of 75 percent of Palmer's ericameria with collection of the seeds hydroseeding from the individuals to be lost for inclusion in the cut and fill slopes. A qualified biologist will be retained to perform mitigation and monitoring tasks and to report in letter form to the City as each of the tasks are completed. In addition to these measures, the California Department of Fish and Game (CDFG) and the U.S. Army Corp of Engineers (ACOE) Will review and comment on the proposed project's implementation, as determined necessary by a qualified biologist. ° With respect to transportation/circnlation (DEIR, pg. 4-69), mitigation measures have been identified which reduce direct impacts to below a level of significance. Resolution No. 90-095 Page 55 ao Improvement of the public portion of Old Coach Road to collector arterial standards, half width improvement of Espola Road and signali.zation of the Old Coach Road/Espola Road intersection will be made conditions of approval of the tentative map. The City Engineering Department will ensure that improvements are in place prior to building permit issuance for residential lots. A traffic signal at Espola Road and Old Coach Road will be installed and accepted by the City prior to issuance of a building permit for the golf course club house facility or issuance of the 41st residential building permit, whichever occurs first. Co Developer will pay their fare share portion for the construction of dual left turn lanes for the south bound approach of Pomerado Road and for the east bound approach of Rancho Bernardo Road at subject intersection. With respect to noise (DEIR, pg. 4-88), mitigation measures have been identified which reduce impacts to below a level of significance. These measures include: ao All operations conducted on the premises, including the warming up, repair, arrival, departure, or running of trucks, earthmoving equipment, construction equipment, and any other associated equipment, shall be limited to the period between 7:00 a.m. and 5:00 p.m. each day, Monday through Friday, and no earthmoving or grading operations shall be conducted on the premises on Saturdays, Sundays, or legal holidays. Any requests for work on Saturdays, Sundays, or legal holidays must be submitted in writing 72 hours prior to work. Additional inspection fees shall be paid in advance of approval. bo Construction machinery with noise levels greater than 100 dB within 50 feet of the nearest receptor will be prohibited or shielded to reduce noise to this level. The on-site construction engineer shall conduct a minimum of two noise level tests weekly to reduce noise to this level adjacent to major machinery. Co Prior to approval of building permits for lots adjacent to Old Coach Road and Old Coach Way, as shown on the revised Tentative Map (4-25-90), the 60 dBA noise contour will be shown on all site plans, and appropriate conditions for noise attenuation measures (e.g., acoustical barriers, and architectural design) will be required if adequate set-backs are not obtained. Resolution No. 90-095 Page 56 With respect to air quail _ty (DEIR, pg. 4-101), project-generated vehicular emissions were considered 'less. than significant. To minimize short-term construction generated air quality impacts, measures were identified which will reduce !mpacts to below a level of significance. These measures include: no To control construction emissions, the use of dust control measures,. such as water sprinkling, cleaning, and sweeping, will be required to minimize fugitive dust. bo Routing of construction vehicles to avoid passing near residences or other sensitive receptors when possible. With respect to cultural resources (DEIR, pg. 4-112), the project has the potential to affect six significant archaeological sites. These impacts can be mitigated with a program of either preservation or data recovery. Mitigation measures identified include: ao Site SDi-ll, 522 must retain the rock enclosures at the south end of the site in an easement designated specifically for archaeology and fenced to prevent intrusion. b. Prior to approval of the grading plan, the development of a research ..................... design, covering the exact, mitigation program (e.g., preservation of site, preservation and reconstruction, and data recovery) to be implemented at each site. In addition, any open space easements to be employed as mitigation must be legally attached to the tentative map and this map must be reviewed for accuracy by the consulting archaeologist. Ce On commencement of development, an archaeologist must be on- site for initial brushing and first grading and must meet with the grading contractors and field supervisors prior to disturbing the site to delineate sensitive areas and areas to be avoided. do The on-site archaeologist will have the authority to stop or redirect grading should any archaeological materials or deposits be discovered which were not identified during archaeological survey. eo Discovery of new archaeology sites during grading will require-an analysis of significance and completion of a mitigation program when necessary. If measures are needed to mitigate impacts from continuation of grading, these must be completed prior to grading of the area. With respect to soils/geology (DEIR, pg. 4-121), the site contains several soils and geologic constraints to future development including non-rippable Resolution No. 90-095 Page 57 granitic rock, compressible alluvium and near surface groundwater. The proposed residential building pads and the clubhouse site substantially avoid the alluvial soils with the exception of portions of six lots. Some development.would overlay granitic rock which would require blasting. Mitigation measures have been identified which reduce geotechnical impacts to below a level of significance, these include: ao Prior to approval of the final grading plan., a geotechnical analysis' will be prepared to provide detailed information to define site specific remedial mitigation measures and potential constraints. All remedial measures which address expansive soils will be recommended by a registered engineer. Any recommended measures will be incorporated as conditions on the final map. The City Engineer would examine the analysis and recommended mitigation for adequacy. bo To mitigate potential damage associated with the possibility of groundshaking, all structures must be constructed in conformance with the Poway Grading Ordinance and Uniform Building Code. The City Engineer must verify that all structures are in conformance with Ordinance and Code. With respect to hydrology/drainage and water quality (DEIR, pg. 4-128), the proposed project is substantially in conformance with the policies and intent of the General Plan. The project would not involve the placement of structures within the 100 year floodplain, except for the widening of Old Coach Road. Areas to be developed with slopes over 25 percent would be developed in a sensitive manner. Impacts associated with the proposed project are considered to be less than significant with compliance of identified mitigation measures. These measures include: ao Prior to final map approval, the City will ensure that the developer submits verification that an adequate drainage system has been provided. bo Site specific hydrological studies will be completed for each drainage basin. The use of energy dissipators will be incorporated at all drainage discharge points to reduce discharge velocity to less than six feet per second and to control ,erosion. Co The provision of desiltation basins and/or detention basins may be used to control runoff quality and quantity. Ultimate design and maintenance will be determined by the City Engineer. Standard erosion techniques, hydroseeding all slopes and pads after grading and limiting all hillsides to 2:1 slopes will be incorporated. 10. Resolution No. 90-095 Page 58 The applicant will conduct soil testing periodically (not less than once a month) to provide data to adjust chemical use (fertilizers, pesticides, etc.) applications to the proper amount. In addition, a water .quality testing program will be required. The frequency of testing will be determined by. the City Engineers. Results will be submitted to the City Engineer for approval. Recommended adjustments will be responsibility of the applicant. The selection of pesticides and fertilizers will be in accordance with the Safe Drinking Water and Toxic Enforcement Act of 1986. In accordance with recommendations contained in the HEC-2 Study, further detailed drainage studies will be done to clarify the velocities at stations 3, 25, and 26, discharge into existing swales and drainage courses leading into Sycamore Creek, and the determination of conveyance change downstream of Sections 3-6, 14, 15, 17, 20, 21, and 27. With respect to utilities and public service (DEIR), pg. 4-139), mitigation measures have been identified for schools and water services. Specific, on- site and off-site impacts and mitigation measures-with regard to sewer service cannot be quantified until a detailed sewer feasibility study is completed. Mitigation measures for utilities and public service include the following: no bo ce eo Developer fees generated by the proposed project, at a rate designated at the time of project implementation, will mitigate all impacts to the school system. Prior to approval of Development Review or Minor Development Review application, all residential construction will be required to utilize water conservation measures (e.g., drought-tolerant landscaping, dual piping for use of reclaimed water, etc.) The applicant will perfom~ a ground water hydrology analysis to determine the feasibility of the use of ground water until reclaimed water is available. This report will be submitted to the City Engineer for review and consideratibn. A detailed sewage collection and distributi'on system/improvement feasibility study will be prepared and approved by the Engineering Services Department prior to final map approval. A water system analysis to establish the proper size and location of the public water system will be required. 9 11. 12. 13. 14. Resolution No. 90-095 Page 59 With respect to recreation facilities (DEIR, pg. 4-155), mitigation measures have been identified which' reduce project impacts to below a level of significance. These measures include the following: ao Prior to approval of the final map, dedication of parkland relative to population impact or the payment of developer's fees in conformance with the General Plan and Chapter 16.38 of the Poway . Municiple Code. bo All trails will be developed in accordance with the trail standards of the Trails Element of the General Plan and approved by the directors of the Poway Planning and Community Services. With respect to population/growth inducement (DEIR, pg. 4-163), the project is in conformance with the policies of the General Plan and would not induce new growth. No mitigation is necessary, therefore no measures have been identified. With respect to socio-economic factors (DEIR, pg. 4-166), the project would not significantly increase the population or available housing especially if project construction is phased. Since the project is not considered to have a significant adverse impact upon the economic base of Poway, no mitigation is necessary. With respect to health, safety, nuisance factors (DEIR, pg. 4-171), significant impacts have been identified with respect to fire protection, emergency medical services (paramedics) and flooding hazards. No potentially significant impacts were identified with respect to law enforcement and hazardous material. Mitigation measures have been identified which will reduce impacts to fire protection, emergency service and flooding, to below a level of significance. Measures regarding the above include the following: ao In the project area where response times would be greater than five minutes, all residential homes will be required to install a fire sprinkler system. bo Co A Wildland Fuel Mitigation Plan will be submitted for approval to the Directors of Safety Services, Planning Services, and Community Services prior to building occupancy. The City Fire Marshal shall review and. approve any proposed structures and landscaping design required to reduce service impacts. The applicant will be assessed a fare share portion of the cost for a new paramedic unit. 10 Resolution No. 90-095 Page 60 15. eo Every deed of sale will include a statement informing affected buyers of the potential safety hazard associated with dam failure. With respect, to cnerev and scarce resources (DEIR, pg. 4-181), increased demand for energy al~l water is not regarded as a significant impact at this time as supply is currently available to serve the project. Both resources are however, sensitive issues, particularly'water supply which is subject to drought conditions. In conjunction with regional .development, the project is considered to have incremental and cumulative effects. With this in mind, the following mitigation measures have been identified: ao The Specific Development Plan 89-01 will incorporate the Po~vay Comprehensive Plan guidelines for energy efficient residential development. Conservation policies of the General Plan will be incorporated into the project design as follows: 1. Installation of water conservative appliances and facilities. Usage of primarily drought-tolerant, plants and scrubs in landscaping. 3... State-of-the-art irrigation systems in common green areas. 4. Installation of dual piping for the use of reclaimed water for public irrigation when it becomes available. c. The City and the Architectural Review Committee as established by the Specific Plan must review all project development for ......... conformance_with energy and water conservation measures. B. The City of Poway, as lead agency and decision maker, having reviewed and considered the information contained in the final EIR for the project and the public records, fmds that there are changes or alterations to the project which avoid or substantially lessen the significant environmental impacts, specifically, implementation of the mitigation measures detailed above. Co The C!ty of Poway, as lead agency and decision maker, having reviewed and considered the information contained in the final EIR for the project and the public record, f'mds there are no specific economic, social, or other considerations which make infeasible the mitigation measures in the EIR. With regards to the project alternatives, several issues may render any part or all of each alternative(s) infeasible for reasons included below: Under the No Project Alternative/Maintain Existing Conditions, no development would occur. The site would remain vacant except for the 11 Resolution No. 90-095 Page 61 o existing fire station, water .reservoir, and one residence. Significant but mitigable impacts to biology, lahd use, and landform alteration would not occur. However, adoption of this alternative is considered infeasible as no proposals of.public financing to change the zoning to permanent public open space have been made. With regards to the No Project/Existing General Plan, the site would be. developed with 164 lots as per the General Plan land use and zoning designations (RR-A, RR-B, and RR-C) with no golf course. This alternative would alleviate the potential for the above identified impacts, but would not result in significant impacts to the Circulation Element. Buildout under this alternative would result in 6,300 ADT which is 25% greater than the proposed project. This alternative was evaluated in concept and an evaluation at the tentative map level would be necessary, to identify site specific impacts. With regards to the Reduced Density Alternative, the Existing General Plan alternative would be reduced to 130 units and the golf course and related facilities also would not be developed. Impacts to landform, noise, air quality, water quality, utilities and public services, and police and fire service would be less than the proposed project or the No Project/Existing General Plan alternative due to less intense development. Traffic impacts would be greater than the proposed project, but less than the No Project/Existing General Plan alternative. All other impacts would be similar to the proposed project. This alternative would not involve any recreational uses which would not implement the concept of the Old Coach Special Study designation in the General Plan; however, this is regarded as not significant. With regards to the Environmentally Sensitive Alternative, 164 single-family homes, and an 18-hole golf course with clubhouse would be constructed. Homes would be clustered in higher density areas on 10,000 square foot lots to reduce impacts in areas with sensitive topography or biology. This alternative would alleviate the potential for significant biological and visual impacts identified for the proposed project. However, on a plan-to-plan and plan-to-adjacent land use analysis, this alternative would pose impacts as it may not be consistent with General Plan rural residential zoning designations and surrounding land uses. With regards to the Alternative Site Location, this land use site was evaluated and it was determined that it was not 6nvironmentally preferred because of potential impacts to traffic, biology, archaeology, and public facilities. Additionally, the purpose of the proposed project was to implement the City's Old Coach Special Study Area. Implementation of the alternative site would not eliminate the need for preparing a Specific Plan the Old Coach site. 12
