Braddock and Logan submitted a related general and specific plan amendment and PD-Planned Development district rezoning with Stage I Development Plan for future development of up to 3,108 dwellings at a variety of densities; up to 2,503,175 square feet of commercial, office, light industrial and mixed use development; two elementary school sites, parks, utility extensions and open spaces located on an approximately 1,134 acre site located in an area bounded by 1-580 to the south, Fallon Road and the Dublin Ranch development to the west, the easterly Dublin city limit line to the east, and the northerly Dublin city limit line to the north. These applications for the entire 1,134 acre area comprise PA 04-040 and are referred to herein as the "Fallon Village project" or the "project"; and WHEREAS, Braddock & Logan also submitted development applications for a portion of the project area, including a PD-Planned Development District rezoning with Stage 2 Development Plan, vesting tentative maps, development agreement and lot line adjustment for development of the northerly 488 acres of the project area. These development applications comprise PA-05-038 and are referred to herein as the "Developer's project" The Developer's project proposes approximately 1,043 single family lots, a 5 acre neighborhood park, a 4.6 acre neighborhood square, a 10 acre parcel reserved for an elementary school, and land designated for semi-public uses; and WHEREAS, the project area is within the Dublin city limits. The southerly 496 acres are within the boundaries of the Eastern Dublin Specific Plan (EDSP) area; the northerly 638 acres lie outside the EDSP planning area; and WHEREAS, the project site is in Eastern Dublin for which the City adopted the Eastern Dublin General Plan Amendment and Specific Plan to provide a comprehensive planning framework for future development of the area. In connection with this approval in 1993, the City certified a program EIR pursuant to CEQA Guidelines section 15168 (SCH No. 911 03064, Resolution 51-93, and Addendum dated August 22, 1994, hereafter "Eastern Dublin EIR" or "program EIR") that is available for review in the Planning Department and is incoroorated herein bv reference. The program EIR was integral to the planning process and examined the direct and indirect effects, cumulative impacts, broad policy alternatives, and areawide mitigation measures for developing Eastern Dublin; and WHEREAS, the Eastern Dublin EIR identified potentially significant environmental impacts and related mitigation measures, which the City adopted together with mitigation findings and a Mitigation Monitoring Program (Resolution 53-93), which mitigation measures and monitoring program continue to apply to development in Eastern Dublin including the Fallon Village project; and WHEREAS, in 2002, the City approved an annexation, prezoning and related PD-Planned Development District Stage I Development Plan for the project area. A Supplemental EIR was certified Reso # 222 - 05, adopted 12/6/05, Item 6.2 PaQ:e 1 of39 for the 2002 project (SCH No. 2001052114, Resolution 40-02), is available for review in the Planning Department and is incoroorated herein by reference. The 2002Supplemental EIR identified potentially significant supplemental environmental impacts and related supplemental mitigation measures, which the City adopted together with mitigation findings and a Mitigation Monitoring Program (Resolution 40-02). The 2002 Supplemental EIR mitigation measures and monitoring program continue to apply to the Fallon Village project; and WHEREAS, both the Eastern Dublin EIR and the 2002 Supplemental EIR identified potentially significant environmental impacts that could not be avoided by mitigation. The City adopted Statements of Overriding Considerations pursuant to CEQA in connection with approval of the 1993 and 2002 projects; and WHEREAS, the City prepared an Initial Study for the Fallon Village project consistent with CEQA Guidelines sections 15162 and 15163 and determined that a supplement to the Eastern Dublin EIR and 2002 Supplemental EIR was required in order to analyze substantial changes in the project and circumstances and new information that could result in new or potentially more severe significant impacts than identified in the previous EIRs; and WHEREAS, a Notice of Preparation dated June 10, 2005 was circulated with the Initial Study to public agencies and interested parties for consultation on the scope of the 2005 Supplemental ErR, and WHEREAS, based on the Initial Study and responses to the Notice of Preparation, the City prepared a Draft Supplemental EIR dated August 2005 (SCH No. 2005062010) and referred to herein as the 2005 Draft Supplemental EIR. The 2005 Draft Supplemental EIR reflected the independent judgment of the City as to the potential environmental effects of the project and was circulated for the required 45 day public review period, from August 23, 2005 to October 6, 2005, and WHEREAS, the City prepared a Final Supplemental EIR dated November 2005 containing written responses to all comments received during the public review period, which responses provide the City's good faith, reasoned analysis of the environmental issues raised by the comments; and WHEREAS, the City Council and Planning Commission held a joint workshop on AprilS, 2005 to provide direction to staff on the project description. The Planning Commission held a study session on the project on October 25, 2005 Staff reports for the workshops dated AprilS and October 25, 2005, respectively are incoroorated herein by reference. A staff report dated November 8, 2005, and incoroorated herein by reference, described and analyzed the 2005 Draft and Final Supplemental EIRs and the project for the Planning Commission; and WHEREAS, staff prepared an errata sheet to identify the following clarifications and revisions to the November 2005 Final Supplemental ErR, which errata are incoroorated herein by reference and were presented to the Planning Commission at the November 8, 2005 public hearing: I Page 7 Item 19, Table 4.2.12 was incorrectly printed in the DSEIR due to reliance on an earlier draft of the transportation analysis of the Fallon Village project, not due to more recent traffic information as stated in the FSEIR. Table 4.2.12 as shown in the FSEIR is the correct table. 2. Page 8 Item 21 is changed as follows: Amended Supplemental Impact TRA-2 as shown on this page is replaced by the following amended language on the bottom of page 64 of the DSEIR with the paragraph beginning with the word "However" Reso # 222 - 05. adopted 1216105, Item 6.2 PaQ:e 2 009 "However, these improvements will not be sufficient to reduce the intersection impacts to an acceptable LOS during the p.m. peak hour Additional improvements to reduce the impacts at the Dougherty RoadJDublin Boulevard intersection to an acceptable LOS would require adding a fourth northbound left turn lane and ether imjlfOvemeHts." 3 Page 12.

The City clarifies that the Downtown Traffic Impact Fee is not applicable to Eastern Dublin projects. 5 Page 46 Table 8 should be titled Table IX, and WHEREAS, the Planning Commission reviewed the staff report, the Draft and Final Supplemental EIRs, and the errata sheet at a noticed public hearing on November 8, 2005 at which time all interested parties had the opportunity to be heard; and WHEREAS, following the public hearing, and based on the record before it, the Planning Commission adopted Resolution 05-57 dated November 8, 2005 and incorporated herein by reference recommending certification of the Supplemental EIR, and WHEREAS, the City Council considered the Planning Commission recommendation, a City Council staff report analyzing the EIR and the Project dated December 6, 2005 and incoroorated herein by reference. the Draft and Final Supplemental EIRs, and all written and oral testimony, at a noticed public hearing on December 6, 2005, at which time all interested parties had the opportunity to be heard; and WHEREAS, the Draft and Final Supplemental EIRs, including the errata items listed above, reflect the City's independent judgment and analysis on the potential for environmental impacts and constitute the Supplemental Environmental Impact Report for the Fallon Village project; and WHEREAS, the Project would have significant effects on the environment, most of which can be substantially reduced through mitigation measures; therefore, approval of the Project must include mitigations and mitigation findings as set forth in Part A below; and WHEREAS, some of the significant effects cannot be lessened to a level of less than significant; therefore, approval of the Project must include findings regarding alternatives as set forth in attached Part B below, and must include a Statement of Overriding Considerations as set forth in Part C below; and WHEREAS, a Mitigation Monitoring and Reporting Program, as required by CEQA, is contained in Part D below; WHEREAS, the Draft and Final Supplemental EIRs are separately bound documents, incorporated herein by reference, and are available for review in the City planning department, 100 Civic Plaza, Dublin, CA, 94568, files P-04-040 and P-05-038 Reso # 222 - 05. adopted 1216/05, Item 6.2 PaQ:e 1 009 NOW, THEREFORE, BE IT RESOLVED THAT the foregoing recitals are true and correct and made a part of this resolution. BE IT FURTHER RESOLVED that the Dublin City Council certifies the following. 1 The Supplemental Environmental Impact Report has been completed in compliance with CEQA, the CEQA Guidelines and the City of Dublin Environmental Guidelines 2. The Dublin City Council reviewed and considered the Supplemental Environmental Impact Report and considered the 1993 program EIR and the 2002 Supplemental EIR prior to approving the Project. 3 The Supplemental Environmental Impact Report reflects the City's independent judgment and analysis on the potential for environmental impacts of the Fallon Village Project. BE IT FURTHER RESOLVED that the Dublin City Council hereby adopts mitigation measures, findings, overriding considerations, and a mitigation monitoring and reporting program for the Fallon Village project as follows: Part A. Findings concerning impacts and mitigation measures Part B Findings regarding alternatives Part C Statement of overriding considerations Part D' Mitigation monitoring and reporting program Part A: Findings concerning impacts and mitigation measures Pursuant to Public Resources Code Section 21081 and CEQA Guidelines Sections 15091 and 15163(e), the City Council hereby makes the following findings with respect to the potential for significant supplemental environmental impacts from the Fallon Village project and means for mitigating those impacts. All mitigation measures previously adopted through the 1993 and 2002 approvals continue to apply to the Project unless modified herein. Many of the impacts and mitigation measures in the following findings are summarized rather than set forth in full. The text of the Draft and Final Supplemental EIRs (SEIRs) should be consulted for a complete description of the impacts and mitigations. Findings pursuant to Section 21081(c) relating to Project alternatives are made in Part B Supplemental Impact TRA-l: Year 2025 project contribution to impact to DublinlDougherty intersection. (DSEIR p 64) SM-TRA-I a) Advance to the City applicable monies for acquisition of right-of-way and construction of the planned improvements at Dougherty RoadlDublin Boulevard. The amount of money advanced to the City shall be based on the developer's fair share of the deficit (spread over those projects which are required to make up the deficit) between funds available to the City from Category 2 Eastern Dublin Traffic Impact Fee funds and the estimated cost of acquiring the right-of-way and constructing the improvements. The City should provide credit for Category 2 Eastern Dublin Traffic Impact Fees to the developer for any advance of monies made for the improvements planned for the Dougherty Rd./Dublin Boulevard intersection. b) Pay a pro-rata share of the cost to construct the planned improvements at Dougherty RoadJDublin Boulevard through payment of the Eastern Dublin Traffic Impact Fee. The City of Dublin will implement these improvements. (DSEIR p. 64.) Reso # 222 - 05, adopted 1216105. Item 6.2 PaQ:e 4 of19 Finding. Even with implementation of the above mitigations, the impact will not be reduced to less than significant. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final SEIR as further set forth in the findings and overriding considerations in Part B and Part C below Rationale for Finding. Through fair share payment and payment of the City's traffic impact fee, the project will provide funds for the identified improvements based on the project's proportionate demand. The mitigations will not reduce the impact to less than significant therefore a statement of overriding considerations will be required for any project approval. Supplemental Impact TRA-2: Year 2025 project contribution to impact the Santa Rita RoadlI-580 eastbound ramps. (DSEIR p. 64 ) SM-TRA-2. Project developers shall contribute a pro-rata share of the cost to widen the 1-580 eastbound off-ramp approach at Santa Rita Road to include a third eastbound left turn lane. (DSEIR p. 65 ) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The widened road will provide increased capacity to improve levels of service during the p.m. peak hour Supplemental Impact TRA-3: Year 2025 project contribution to impact Central Parkway and Hacienda Way. (DSEIR p. 65 ) SM-TRA-3 Project developers shall contribute pro-rata share of the cost to modify the westbound approach on Central Parkway at Hacienda Drive to include two left turn lanes, one through and one right turn lane. (DSEIR p. 66.) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The modification to include two left turn lanes, one through, and one right turn lane will provide a safe configuration for left turns onto southbound Hacienda Drive. Supplemental Impact TRA-4: Year 2030 cumulative impacts to local freeways. (DSEIR p. 69 ) Mitigations: Mitigation measures identified in the Eastern Dublin ErR, as specified on DSEIR pp. 69-71 No supplemental mitigations are identified. Finding. Some of the improvements identified in Eastern Dublin EIR mitigation measures have already been constructed. Other mitigations such as adopting traffic impact fees have been implemented by the City Even with implementation of the above mitigations, the impact will not be reduced to less than significant. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for higWy trained workers, make infeasible the mitigation measures or project alternatives identified in the Final SEIR as further set forth in the findings and overriding considerations in Part B and Part C below Reso # 222 - 05, adopted 1216105, Item 6.2 PaQ:e 5 on9 Rationale for Finding. The previously adopted mitigations will create limited amounts of additional capacity to meet cumulative traffic demand. The mitigations will not reduce the impact to less than significant therefore a statement of overriding considerations will be required for any project approval. Supplemental Impact TRA-5: Year 2015 and 2025 consistency with Alameda County Congestion Management Plan. (DSEIR p. 73 ) Mitigations. No supplemental mitigations are identified. Finding. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final SEIR as further set forth in the findings and overriding considerations in Part B and Part C below Rationale for Finding. All Eastern Dublin projects, including the Fallon Village project, are required to contribute toward regional roadway improvements through payment of the TVTD Fee. However, even with funding from these fees, there is insufficient right-of-way on 1-580 and 1-680 to add capacity through additional mixed flow lanes, therefore the impact remains significant and unavoidable and a statement of overriding considerations will be required for any project approval Supplemental Impact SD-l: Changed non-point surface water quality. (DSEIR p. 123 ) SM-SD-l The Stage 1 Development Plan shall require that the water quality source control and hydrologic design recommendations of the report prepared by ENGEO, Inc. be implemented for all individual development projects within the Project Area. (DSEIR p. 124 ) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. Implementation of the detailed recommendations in the ENGEO report throughout the Project area will ensure compliance with applicable NPDES water quality requirements. Supplemental Impact SD-2: Changed non-point surface water quality hydro modification standards. (DSEIR p. 125) SM-SD-2. Development within the Project area shall comply with the hydromodification provisions of the Alameda County Clean Water Program as approved by the RWQCB and administered by the City of Dublin. If no Alameda County Clean Water Program permit has been adopted at the time individual development proposals are approved by the City the applicant may be required to submit hydrology and hydrologic analyses to identify specific increases in storm water runoff into downstream receiving waters. Such reports will be reviewed by both the City of Dublin and Zone 7 Water Agency Development projects will also be required to pay the then-current Zone 7 Special Drainage Area fee (SDA7-1) in effect at the time ofthe development. (DSEIR p. 126.) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. Implementation of the mitigation measure will ensure that project runoff flows and volume for the Eastern Drainage Corridor will be managed so as to comply with applicable water quality standards. Reso # 222 - 05, adopted 1216/05, Item 6.2 PaQ:e 6 009 Supplemental Impact GEO-l: Potential soil hazards due to alteration in the extent of Project grading. (DSEIR p. 130) SM-GEO-l Prior to construction, design level geotechnical report(s) and corrective grading plan(s) depicting the locations and depths of landslide repairs, keyways and subsurface drains is required. The correcting grading plans shall identity appropriate mitigation for graded slopes. In order to stabilize slopes where unstable geologic materials extend at beyond proposed development area, geotechnical corrective grading may extend beyond the limits of improvements and into open space areas. Grading in open space areas shall be limited to excavations that remove unstable soils and landslide debris and backfilling excavations with compacted, drained engineer fills. To provide stable construction slopes, the back slopes of excavated areas may extend up slope and beyond the limits of mapped slides. The corrective measures used will be typical and configured to conform at natural slope contours with materials and compaction at the approval of a geotechnical engineer This may vary from original grade within repair envelope due to geotechnical and slope drainage considerations. (DSEIR pp. 130-131 ) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The requirement for detailed grading plans showing the recommended measures for stabilizing slopes, landslide areas and other unstable soils will ensure that the Project implements appropriate corrective measures to eliminate unstable soils and other soils hazards. 2002 SEIR Impact BIO-2: Loss of special-status plant species (DSEIR p. 167) The 2005 SEIR identified no additional impacts to special-status plant species beyond those in the 2002 SEIR, however, Supplemental Mitigation Measure SM-BIO-4 from the earlier SEIR as adopted in Resolution 40-02 is modified as follows. SSM-BIO-I(revises 2002 SM-BlO-4), If special-status plants cannot be avoided, then the area containing the plant that is to be impacted, and the approximate number of plants to be impacted, must be determined, and the following steps must be taken: (a) harvest seeds from the plants to be lost, or use seeds from another source within the Livermore and Amador valleys, and their surrounding watersheds, and seed an area suitable for supporting the plant, either within the Project area or off-site, at a level sufficient to replace the impacted individuals at a I 1 ratio on an individual plant and basis, and at a ratio no less than 5 I on an occupied habitat basis. The mitigation site shall be preserved and protected in perpetuity If the mitigation site fails to support at least as many plants as were impacted within a five year period, support at least as many plants as were impacted within a five year period, then step "b" below must be implemented; and (b) permanently preserve, through use of a conservation easement or other similar method, an equal amount of acreage either within the Project area or off-site area that contains the plant. Prior to submission of a Stage development plan or tentative map, the developer shall submit a written report to the City for its review and approval demonstrating how the developer will comply with this mitigation measure, including the steps it will take to ensure that transplanting or seeding will be successful. (DSEIR pp. 167-168) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Reso # 222 - 05. adopted 1216105, Item 6.2 PaQ:e 7 0[19 Rationale for Finding. Implementation of the refined mitigation measures of harvesting seeds and permanently preserving appropriate acreage will ensure that previously identified impacts will continue to be reduced to less-than-significant levels through updated measures to avoid or reduce impacts to special- status plants. 2002 SEIR Impact BIO-IO: Burrowing Owls (DSEIR p. 168.) The 2005 SEIR identified no additional impacts to burrowing owl, however, supplemental mitigations SM-BIO-28 through -37 from the 2002 SEIR as adopted in Resolution 40-02 are replaced by the following updated mitigation measures. SSM-BIO-2 (revises 2002 measures). During the breeding season (February I-August 31) prior to submittal of Stage 2 development proposals for a particular parcel, or during a subsequent breeding season but prior to the initiation of construction, a survey shall be conducted according to CDFG protocols to determine whether Burrowing Owls are present, and if present, the number of nesting pairs of Burrowing Owls present on the parcel. SSM-BIO-3(revises 2002 measures). Pre-construction surveys for burrowing owls shall be conducted by a qualified biologist prior to any ground disturbance between September I and January 31 If ground disturbance is delayed or suspended for more than 30 days after the survey, the site should be re-surveyed. If no over-wintering birds are present, burrows should be removed prior to the nesting season. If over- wintering birds are present, no disturbance should occur within 150 feet of occupied burrows. If owls must be moved away from the disturbance area during this period, passive relocation measures must be prepared according to current CDFG burrowing owl guidelines, approved by CDFG, and completed prior to construction SSM-BIO-4(revises 2002 measures), If construction is scheduled during the nesting season (February I - August 31), pre-construction surveys should be conducted on the entire site-specific Project area and within 500 feet of such Project area prior to any ground disturbance. A minimum buffer (at least 250 feet) shall be maintained during the breeding season around active burrowing owl nesting sites identified in pre-construction surveys to avoid direct loss of individuals. Owls present on site after February 1 will be assumed to be nesting on or adjacent to the site unless evidence indicates otherwise. All active burrows shall be identified. If construction around active nests is scheduled to occur when nests are active (i.e., if they contain, or are assumed to contain, eggs or un-fledged young), a 250-foot exclusion zone around the nest shall be established or construction shall be delayed until after the young have fledged, typically by August 31 If owls are present during the early part of the breeding season, and evidence indicates that they have not yet begun nesting, they may be passively relocated from the site if authorized by CDFG SSM-BIO-5(revises 2002 measures). If destruction of occupied (breeding or non-breeding season) burrows, or any burrows that were found to be occupied during pre-construction surveys, is unavoidable, a strategy will be developed to replace such burrows by enhancing existing burrows or creating artificial burrows at a 2:1 ratio on permanently protected lands adjacent to occupied burrowing owl habitat, and will include permanent protection ofa minimum of6.5 acres of burrowing owl habitat per pair or unpaired resident owl. A plan shall be developed and approved by CDFG describing creation or enhancement of burrows, maintenance of burrows and management offoraging habitat, monitoring procedures and significance criteria, funding assurance, annual reporting requirements to CDFG, and contingency and remediation measures. (DSEIR p. 169) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Reso # 222 - 05, adopted 1216105, Item 6.2 PaQ:e 8 0[19 Rationale for Finding. The breeding season surveys will ensure that the presence and number of owls on the site will be determined. The preconstruction surveys and required buffer zone around known nesting and breeding sites will preserve owl burrows by allowing them to be avoided during the construction and development process. The measures will also ensure that replaced and/or enhanced burrows be provided in coordination with CDFG for any unavoidable disturbance. Supplemental Impact BIO-l: Loss or degradation of botanically sensitive habitats. (DSEIR p. 172.) SM-BIO-l Impacts to central coast riparian scrub habitat shall be mitigated through the restoration or enhancement of riparian habitat at a 3 1 ratio (on an acreage basis), preferably within the proposed aquatic and buffer zone or corridor zone management areas on-site. If mitigation within the Project area is not feasible, then the developer shall mitigate impacts to central coast riparian scrub through the restoration or enhancement of riparian habitat at a 3 1 ratio (measured by acreage) at an off-site location acceptable to the City Any riparian mitigation areas shall be preserved and protected in perpetuity Restored habitat shall be monitored for a period offive years including preparation of an annual report each year (DSEIR p. 174.) "A Riparian Mitigation and Monitoring Plan shall be prepared for City review and approval prior to issuance of the first grading permit on any property which contains riparian habitat as identified on Exhibit 47 I of the DSEIR which will detail the steps to be taken to restore and/or enhance coastal riparian scrub habitat within the on-site conservation area or at off-site mitigation lands, pursuant to this mitigation measure This site-specific plan will be prepared once specific on-site conservation areas and/or off-site mitigation lands are identified, and shall also include the following components: 1 Performance standards to ensure successful restoration or enhancement of riparian habitat that focus on plant survival rates, plant size, plant health, canopy cover, and presence of invasive weeds. 2 .Monitoring to evaluate whether the restoration or enhancement measures are satisfying the performance standards. Such monitoring shall occur for five years, or until the restored or enhanced areas meet the performance standards, whichever comes first. A monitoring report will be filed with the City annually 3 Photographic monitoring to visually assess the restoration or enhancement efforts and document changes to this habitat during the length of the monitoring period described above. 4 If monitoring demonstrates that the performance standards are not likely to be met, or are not met, at the end of five years, then specific adaptive management measures will be proposed in the annual monitoring report and implemented the following year, including physical alteration of the hydrological source, replanting or reseeding, removal of pest plants or animals, installation of additional fencing or protective measures, erosion control or repair, active enforcement of recreation area or homeowner policies, and/or other similar measures. 5 Recommended strategies and detailed methods to implement these adaptive management measures shall be proposed in the annual monitoring report and approved by City prior to implementation. (FSEIR pp 4-5, hereby corrected to reference addition of above text to end of mitigation SM-BIO-I on p 174 of DSEIR.) Implement SSM-BIO-2, -3, and -4 below related to breeding habitat for CTS and essential aquatic habitat for CRLF (DSEIR pp. 177-180) Reso # 222 - 05, adopted 12/6/05, Item 6.2 l'aQ:e 9 on9 Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. Previously adopted mitigation measures provide on and/or off-site mitigation for arroyo willow riparian woodland, freshwater marsh, seasonal wetlands, intermittent streams and alkali grasslands. The supplemental impact and mitigation measures recognize and extend such protections to ponds in the project area, which were not specifically identified as sensitive habitat in prior EIRs, by requiring permanent onsite restoration or enhancement in the onsite open space corridor or at an appropriate off-site location. The mitigation measures also require that the details of preserving riparian habitat, including central coast riparian scrub habitat, be set forth in a mitigation plan that provides performance standards and monitoring for the effectiveness of the measures. Supplemental Impact BI0-2: Impacts to California red-legged frogs. (DSEIR p. 174) SM-BIO-2 (revises 2002 SM-BIO-14). Ifavoidance is infeasible, then mitigation lands providing similar or better habitat for CRLF shall be preserved and protected in perpetuity Mitigation will be required at a 3 I replacement ratio for essential aquatic habitat (including verified aquatic breeding habitat) and associated upland habitat within 100 m of essential aquatic habitat, and at a 1.5 1 replacement ratio for dispersal habitat as defined in Exhibit 47.3 of the Draft SEIR. Alternately, the latter ratio may be reduced at the discretion of the City, if additional essential aquatic habitat is provided. The amount of reduction shall be proportional to the amount of additional essential habitat provided, up to a maximum reduction of fifty percent. Because aquatic breeding habitat and perennial water bodies providing summer refugia are expected to limit CRLF population size in the dry eastern Alameda/Contra Costa region more than the availability of suitable upland habitat, flexibility in this mitigation requirement (i.e., to allow for the creation of ponds to serve as partial mitigation and for impacts to upland habitat) provides an opportunity to create greater benefit to CRLF populations on a landscape level. This mitigation shall be proposed in a mitigation monitoring plan submitted to the City In selecting off-site mitigation lands, preference shall be given to preserving large blocks of habitat rather than many small parcels, selecting mitigation land within the Livermore and Amador valleys, and their surrounding watersheds, to account for local loss of proposed critical habitat, linking preserved areas to existing open space and other high-quality habitat, and excluding or limiting public use within preserved areas. (DSEIR p 177) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The revised mitigation measure distinguishes essential aquatic habitat from dispersal habitat and by requiring quantification for the replacement ratios for each, ensures that impacts to both kinds of habitat are adequately protected or otherwise preserved. Supplemental Impact BIO-3: Impacts to California tiger salamander. (DSEIR p 177) SM-BIO-3 (revises 2002 SM-BIO-19). To compensate for the permanent loss of up to 1.24 acres of aquatic CTS breeding habitat, developers of individual parcels will create and/or enlarge suitable breeding ponds at a 2:1 ratio (mitigation to impact. on an acreage basis), in or adjacent to areas currently supporting CTS and with sufficient surrounding upland habitat to provide a high likelihood of establishment and persistence of a breeding population. In selecting off-site mitigation lands, preference shall be given to preserving one large block of habitat rather than many small parcels, selecting mitigation land within the Livermore and Amador valleys, and their surrounding watersheds, to account Reso # 222 - 05, adopted 12/6105, Item 6.2 PaQ:e 10 of39 for local loss of proposed critical habitat, linking preserved areas to existing open space and other high quality habitat, and excluding or limiting public use within preserved areas. Land selected for mitigation shall be permanently preserved through use of a conservation easement or similar method and shall be managed for use by CTS by a conservation entity This mitigation shall be proposed in a mitigation and monitoring plan submitted to the City for approval. (DSEIR pp. 179-180, FSEIR p. 7) SM-BIO-4 (revises 2002 SM-BIO-19). To compensate for the permanent loss of up to 658.3 acres of upland CTS habitat, developers of individual parcels will acquire, preserve, and manage suitable upland habitat at a 1 I ratio (mitigation to impact, on an acreage basis), in or adjacent to areas currently supporting CTS and within 2200 feet of a suitable breeding pond. Alternately, this ratio may be reduced (i.e.. to less than 1 1 mitigation for lost upland habitat), at the discretion of the City, if additional aquatic breeding habitat (beyond that required by SM-BIO-3) is provided. The amount of reduction shall be proportional to the amount of additional essential habitat provided, up to a maximum reduction of fifty percent. Because aquatic breeding habitat is expected to limit CTS population size in the dry eastern Alameda/Contra Costa region more than the availability of suitable upland habitat, flexibility in this mitigation requirement (i.e., to allow for the creation of breeding ponds to serve as partial mitigation for impacts to aestivation habitat) may benefit CTS populations on a landscape level. This mitigation requirement may be combined with SM-BIO-3 of the 2002 SEIR so that the overall mitigation results in creation/restoration and preservation of breeding ponds (to mitigate impacts to aquatic breeding habitat and preservation of associated upland habitat (to mitigate impacts to upland habitat according to SM-BIO-4). In selecting off-site mitigation lands, preference shall be given to preserving one large block of habitat rather than many small parcels, selecting mitigation land within the in Livermore and Amador valleys, and their surrounding watersheds, to account for local loss of proposed critical habitat, linking preserved areas to existing open space and other high quality habitat, and excluding or limiting public use within preserved areas. Land selected for mitigation shall be permanently preserved through use of a conservation easement or similar method, and shall be managed for use by CTS by a conservation entity This mitigation shall be proposed in a mitigation and monitoring plan submitted to the City for approval. (DSEIR p 180, FSEIR p7) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The revised mitigation measure distinguishes aquatic breeding habitat from upland habitat and by requiring quantification for the replacement ratios for each, ensures that impacts to both kinds of habitat are adequately protected or otherwise preserved. Supplemental Impact CUL-l: Prehistoric resources on Fallon Enterprises property. (DSEIR p. 217) SM-CUL-l (a) Prior to the initiation of construction or ground-disturbing activities on the Fallon Enterprises Property, Project developer(s) shall retain the services of a qualified consulting archeologist to train construction personnel to understand the potential for exposing subsurface cultural resources and to recognize possible buried cultural resources. Training shall inform all construction personnel of the procedures that shall be followed upon the discovery or suspected discovery of archaeological materials. including Native American remains, and their treatment; and (b) Upon discovery of possible buried cultural materials (including potential Native American skeletal Reso # 222 - 05, adopted 1216105, Item 6.2 PaQ:e 11 of39 remains), work in the immediate area of the find shall be halted and the Project archaeologist notified. Once the find has been identified and evaluated, the Project archaeologist shall make the necessary plans for treatment of the find(s) consistent with CEQA Guidelines Section 15064.5 State law shall be followed in the event of the exposure of Native American skeletal remains. This measure shall be included on all grading and construction plan. State law shall be followed in the event of the exposure of Native American skeletal remains. This measure shall be included on all grading and construction plan. (DSEIRp.217) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. These mitigations ensure that construction personnel will recognize if buried cultural resources are uncovered, and will ensure that any such resources are not disrupted or destroyed. Supplemental Impact CUL-2: Fallon Ranch house. (DSEIR p. 218) SM-CUL-2. The following steps shall be taken to preserve and protect the historic Fallon Ranch house. Implementation of mitigations (a) or (b) will reduce the impact to a less than significant level. Implementation of mitigations (c), (d) and/or (e) will reduce the impact but not to less than significant. (a) Retain the building on its historic site and rehabilitate it according to the Secretary of the Interior's Standards and Guidelines for Rehabilitating Historic Buildings (U.S. Department ofthe Interior 1994). This mitigation measure would reduce the impact to a less-than-significant level. This measure may not be feasible given the residential development planned for the property (DSEIR p. 218.) (b) Move the house to a different location consistent with its historic residential character and rehabilitate it according to the Secretary of Interior's Standards and Guidelines for Rehabilitating Historic Buildings. The feasibility of moving the buildings can only be determined by a contractor or engineer experienced in moving historic buildings. Generally, it is feasible to move small wood-frame buildings like the house at 5781 Fallon Road. The historic integrity of a building eligible under California Register Criterion 3 is usually not seriously compromised if it is moved, thus it is not considered to be a "substantial adverse change." (DSEIR p. 218.) (c) Representatives ofthe Dublin Planning Department, the Dublin Historical Preservation Association, the Dublin Parks and Community Services Department and other interested parties should be given the opportunity to examine the house and provide suggestions for salvaging and relocating elements. (FSEIR p. 8 ) (d) The documentation, with original photo prints and negatives, should be placed in an historical archive or history collection accessible to the general public, such as the Dublin Heritage Center Museum. (FSEIR p. 8.) (e) Develop a public exhibit/education program on the Fallon Ranch and history of cattle ranching in the Dublin area at the Dublin Heritage Center The exhibit could incorporate the documentation and interpretative materials developed for Mitigation Measure 4 regarding the significant role of ranching in local history (DSEIRp. 219) Finding. Mitigations (a) and (b) are infeasible for the reasons set forth in the Braddock & Logan letter dated November 3, 2005, on file in P A 04-040 and incoroorated herein bv reference. These reasons include the fact that the house is located in a low area on the site with existing Dublin Ranch development Reso # 222 - 05, adopted 1216/05, Item 6.2 PaQ:e 12 of 19 to the west, and planned residential development to the east. Development ofthe planned residential uses will require raising grade levels to efficiently extend utilities to and to develop the residential area; it would not be feasible as a practical matter to maintain the house at its low elevation with development on either side. The structure itself is fragile and built on a foundation of stones. The single wall construction contributes to the structure's distinctive characteristics but makes it very difficult to move without compromising what structural integrity remains. The structure has also been modified over the years which further compromises its historical distinction and makes it difficult to determine what features of the structure should be retained. As a further practical matter, it is difficult to find a group interested in moving and restoring historical structures, and also difficult to find a receiver site for such structures. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final SEIR as further set forth in this finding and in the findings and overriding considerations in Part B and Part C below Rationale for Finding. Salvage and/or documentation will preserve some aspects of the historic structure but not sufficiently to compensate for the loss of the structure, therefore, the impact remains significant and unavoidable and a statement of overriding considerations must be adopted for any project approval. Supplemental Impact CUL-3: Cultural Resources on Jordan and Chen properties. (DSEIR p 219) SM-CUL-3 Prior to approval of a Stage 2 Development Plan for the Jordan and Chen properties, a detailed cultural resources assessment of combined historic/prehistoric site at the 4J Ranch site (CA-Ala- 508/H) shall be conducted to determine if the site is eligible for the California Register of Historical Resources. All mitigation measures identified in that study shall be incorporated into the Stage 2 Development Plan approval conditions. (DSEIR p. 219) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The required cultural resources assessment ensures that specific development projects will determine the presence and extent of any sensitive resources and will provide appropriate protection to avoid inadvertent destruction of the resources. Supplemental Impact CUL-4: Croak Ranch historic resonrces. (DSEIR p. 220.) SM-CUL-4. Prior to approval of a Stage 2 Development Plan for the Croak property, a detailed historic resources assessment of Croak Ranch Homestead site shall be conducted to determine if the site is eligible for the California Register of Historical Resources. All subsequent measures identified in such study shall be incorporated into the Stage 2 Development Plan approval conditions to ensure that historic resources on the property are preserved. (DSEIR p. 220 ) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The required cultural resources assessment ensures that specific development projects will determine the presence and extent of any sensitive resources and will provide appropriate protection to avoid inadvertent destruction of the resources. Supplemental Impact NOISE-I: Aircraft Dyovers. (DSEIR p.226.) Reso # 222 - 05, adopted 1216/05, Item 6.2 PaQ:e 13 009 SM - NOISE-l All occupants of the residential dwellings within the proposed Project shall receive written notification at the time of sale, rental or lease of the potential for aircraft overflights of the Fallon Village Project area. Written notices shall be approved by the Dublin Community Development Director (DSEIR p. 226.) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The required notice ensures that potential future residents of the Project will be aware of possible overflight noise before they make a decision to locate within the Project. Supplemental Impact NOISE-2: Future roadway noise affecting proposed residential development on the Braddock & Logan properties north of Upper Loop Road and East of Creek Road. (DSEIR p.227 ) SM-NOISE-2. An acoustical study must be prepared for the project. The study shall show how the project will meet an indoor goal of 45 dBA CNEL. In addition, the study must show how noise in outdoor areas will meet the level ofa CNEL of60 dBA (CNEL of65 dBA at City's discretion). Based on preliminary site development information it is likely that the project can meet the indoor goal with regular double glazed windows (no special sound rating). A noise barrier may be required if backyards or other primary outdoor use spaces are located adjacent to either Croak Road or Upper Loop Road. (DSEIR p. 227 ) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. Through the requirement for an acoustical analysis, the mitigation ensures that applicable noise standards will be met as development is implemented. Snpplemental Impact NOISE-3: Compatibility of school and neighborhood park on Braddock & Logan properties with future roadway noise. (DSEIR p.227) SM-NOISE-3 The design of the elementary school and neighborhood park shall consider noise reduction measures to comply with City exterior noise exposure limits including but not limited to appropriate siting of improvements, use of noise barriers and similar noise reduction techniques as may be needed. (DSEIR p 228.) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The mitigation ensures that noise reduction measures will be built into the design of the school and park so as to meet applicable noise standards. Supplemental Impact NOISE-4: Noise from Upper Loop Road on Braddock & Logan properties affecting existing residences. (DSEIR p. 228.) SM-NOISE-4 Noise from Upper Loop Road is expected to generate a CNEL in excess of 60 dBA. The existing homes along the existing alignment of Fallon Road are currently exposed to an Ldn of about 56 to 59 dBA. It is unlikely but possible that the noise from Upper Loop Road would cause noise levels to increase by more than 6 dBA at these existing homes. However, an evaluation of noise from Upper LooprReso # 222 - 05, adopted 1216105, Item 6.2 PaQ:e 14 of 39 Road on existing dwellings shall be made and if it is found that the road would increase noise by more than 6 dBA in backyards of those existing homes, then appropriate noise mitigation measures (i.e. roadway alignment or noise barrier) shall be included in the new roadway design. (DSEIR p. 228.) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The required noise evaluation and implementation of mitigation if necessary, will ensure that existing residents will not be exposed to substantial increases in ambient noise from the new roadway Supplemental Impact AQ-l: Construction related air quality impacts. (DSEIR p. 238.) SM-AO-l. In addition to measures identified in Mitigation Measure 3 11/1 0 of the East Dublin EIR, the City of Dublin shall: (a) Require construction contractors to water or cover stockpiles of debris, soil, sand or other materials that can be blown by the wind, (b) Require construction contractors to sweep daily (preferably with water sweepers) all paved access road, parking areas and staging areas at construction sites; and (c) Require construction contractors to install sandbags or other erosion control measures to prevent silt runoff to public roadways. (DSEIR p. 239) Findin~. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Findin~. The mitigation ensures that additional dust control measures will be implemented to reduce and control fugitive dust and erosion during construction. Supplemental Impacts AQ-2, AQ-3, Project level and cumulative increases in regional emissions that would exceed BAAQMD thresholds for ozone precursors. (DSEIR pp. 239-240 ) SM-A0-2. In addition to measures identified in MM 3 11150-11.0 of the East Dublin EIR, the City of Dublin shall require that the following be implemented: a) The Project proponent should coordinate with LA VTA for the eventual extension of transit service to the Project area. Project proponents should construct or reserve necessary right-of-way for transit facilities such as bus turnouts/bus bulbs, benches, etc. b) Bicycle land and/or paths, connected to community-wide network should be provided as part of the Stage 1 Development Plan. c) Sidewalks and/or paths, connected to adjacent land uses, transit stops, and/or community-wide network should be provided as part of the Stage 1 Development Plan. d) Consider shuttle service to regional transit system or multimodal center e) Consider providing a satellite telecommute center for Project residents if this is feasible in terms of a convenient location. f) Provide interconnected street network, with a regular grid or similar interconnected street pattern. (DSEIR p. 240.) Finding. Even with implementation of the above mitigations, the impact will not be reduced to less than significant. Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final SEIR as further set forth in the findings and overriding considerations in Part B and Part C below Reso # 222 - 05, adopted 1216/05, Item 6.2 PaQ:e 15 009 Rationale for Finding. The above mitigations would reduce vehicle trips, which are the primary source of ozone precursors, but not enough to reduce the impact to less than significant. A statement of overriding considerations will be required for any project approval. Supplemental Impact HAZ-l: Potential for exposure to asbestos-containing materials and lead- based paints. (DSEIR p. 247) SM-HAZ-1. Prior to the demolition of any structures identified in the Environmental Site Assessments as potentially containing ACM's orIead-based paints, Project developer(s) shall undertake comprehensive asbestos and LBP surveys of those structures and implement appropriate ACM and LBP handling and disposal methods based on those surveys. As recommended in the ENGEO 2005 report, an environmental professional shall be present during demolition and pre-grading activities to inspect for potential environmental contaminants. (DSEIR p 247) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The mitigation ensures that any asbestos-containing materials or lead-based paint will be identified and that appropriate removal and disposal regulations will be complied with. Supplemental Impact HAZ-2: Potential for soil/groundwater contamination and exposure hazards from existing hazardous materials. (DSEIR p. 247 ) SM-HAZ-2. As identified in the Environmental Site Assessments for each property, all observed hazardous or potentially hazardous materials and potential containers of those materials shall be removed from the properties by licensed waste contractors prior to building demolition. If no building demolition is required, this removal shall be completed prior to any grading activities on an individual site. The contents of potential hazardous material containers shall be identified and disposed of accordingly, including specific methods to preclude airborne release of materials. All dumped scrap and miscellaneous material and equipment shall be removed from the site prior to anyon-site development activities. If recommended in the ESA (i.e. Mandeville, Anderson, and Fallon Enterprises properties), an environmental professional shall view the property during demolition and pre-grading activities to ensure compliance with this measure. (DSEIR pp. 247-248 ) Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. Proper identification, handling and disposal of any hazardous materials on the site ensures that soils and groundwater will not be exposed to contamination. Supplemental Impact HAZ-3: Potential for soil/groundwater contamination from subsurface contamination. (DSEIR p. 248.) SM-HAZ-3 (a) A Phase II ESA shall be conducted for the former gas station site north and west of Croak Road to obtain information with regard to operation, demolition, and removal of the former gasoline service station in order to better assess the likelihood of this use having a detrimental impact to soils and water quality at the EBJ site and adjacent sites. This Assessment shall be completed and approved by the Alameda County Fire Department prior to any demolition or site grading, whichever is first. Additionally, a limited subsurface investigation shall be conducted for the EBJ parcel and adjacent Reso # 222 - 05, adopted 1216/05, Item 6.2 PaQ:e 16 of39 areas of the Anderson and Chen/Tseng properties to better assess whether impacts to soil and shallow groundwater have resulted from the former gas station (b) All identified potentially contaminated areas on the Jordan Ranch site shall be remediated as identified in the Phase I ESA. In addition, as identified in the Phase II ESA, the Jordan Ranch owner shall inform the Alameda County Environmental Health Services Department (ACEHSD) of an unauthorized release of fuel hydrocarbons as diesel and gasoline in the vicinity of the removed underground fuel tank at the site. The property shall be subject to further subsurface investigations to evaluate the lateral and horizontal extent of the contamination, and to evaluate whether ground water has been affected, and shall be remediated as directed by the ACEHSD Further site assessment, including soil and groundwater sampling and testing, shall be conducted to evaluate the horizontal and lateral extent of impact to underlying soils and groundwater A limited Phase II ESA, including soil and groundwater sampling, shall be conducted to evaluate the potential impact on underlying soils and groundwater within the area of the diesel storage drums, weed killer, and other storage containers in Barn 2, as well as in the vicinity of the stored fuel containers and farm equipment in Barn 1 During removal of hazardous material contaminant sources at the Jordan Ranch site, a qualified environmental assessor shall be present to observe the removal and conditions exposed during that removal. After the removal of these sources from the site, and any excavation to remove contaminated soil, additional soil sampling and laboratory testing shall be conducted to confirm that the contaminated materials have been removed. Ifpotentially hazardous substances are identified, remediation plan(s) shall be prepared by a qualified consulting and approved by an appropriate oversight agency A worker safety plan shall be included in all remediation plans (c) A Phase II ESA shall be conducted for the portion of the Fallon Enterprises property where the buried household garbage dump is located. The assessment shall include soil sampling and testing to evaluate the potential impact to underlying soils. The assessment shall be completed and approved by the Alameda County Fire Department prior to site grading operations. If potentially hazardous substances are identified in the Phase II ESA, remediation plan(s) shall be prepared by a qualified consulting and approved by an appropriate oversight agency A worker safety plan shall be included in all remediation plans (d) A Phase II ESA shall be conducted for the portion of the Anderson property used by Pleasanton Trucking and Materials. That assessment shall include soil sampling and groundwater testing to evaluate the potential impact to underlying soils. If potentially hazardous substances are identified in the Phase II ESA, remediation plan(s) shall be prepared by a qualified consulting and approved by an appropriate oversight agency A worker safety plan shall be included in all remediation plans (e) A Phase II ESA shall be conducted for the portion of the Branaugh properties used by Branaugh Excavating, Branaugh Transportation, and the Golden StatelExecutive Landscaping Companies. That assessment shall include soil sampling and groundwater testing to evaluate the potential impact to underlying soils. If potentially hazardous substances are identified in the Phase II ESA, remediation plan(s) shall be prepared by a qualified consulting and approved by an appropriate oversight agency A worker safety plan shall be included in all remediation plans. (f) Upon development of each site, all existing wells shall be abandoned under permit from Zone 7 Water Agency and in accordance with all applicable regulations. (g) When, or prior to, the existing structures are demolished, all existing septic systems and associated leach fields shall be pumped out and removed under permit from the Alameda County Health Department. (DSEIR pp. 248-249 ) Reso # 222 - 05, adopted 1216105, Item 6.2 Palle 17 of19 Finding. Changes or alterations have been required in, or incorporated into, the Project that avoid or substantially lessen the significant supplemental effect identified in the final SEIR. Rationale for Finding. The Phase II ESAs will ensure that any subsurface contamination is identified and that appropriate remediation plans are prepared. The mitigations further require remediation of identified contamination sites so that contamination will be removed before development occurs. Requirements for a worker safety component of the remediation plans ensures that contamination will not harm workers during the remediation process. Because environmental testing and remediation will occur before development, the impacts will be mitigated to less-than-significant levels. Part B: Findings concerning alternatives. The Eastern Dublin EIR identified four alternatives: No Project, Reduced Planning Area, Reduced Land Use Intensities and No Development. The City Council found the No Project, Reduced Land Use Intensities and No Development alternatives infeasible and then approved a modification of the Reduced Planning Area alternative. The 2002 SEIR identified additional alternatives including the Mitigated Traffic Alternative, Development under the County General Plan, and a No Development Alternative. Since the 2005 SEIR identified significant unavoidable cumulative traffic impacts (i.e., at the DublinIDougherty intersection, and for cumulative freeway conditions) and air quality impacts due to increased ozone precursors that are generated primarily by traffic, the 2005 SEIR identified a Reduced Project Development Alternative to examine whether reduced land use densities would avoid the significant traffic and air quality impacts. The 2005 SEIR also updated the no project and no development alternatives. Since publication ofthe Draft Supplemental EIR, developers of the Braddock & Logan properties have determined that the Fallon Ranch House will be demolished; as noted in the DSEIR, this is a significant unavoidable impact. The major changes from the 2002 project include identification of a central open space corridor, increased residential development, and increased commercial development to be located in the AP A. The 2005 SEIR identified and analyzed several limited scope alternatives primarily intended to provide the City with information on site use and design options related to the above major changes. The alternatives analysis is presented in Section 5 0 of the 2005 SEIR, as amended by the Final SEIR. (DSEIR pp. 255- 278, FSEIR p. 8-9 ) The City Council hereby finds that the alternatives identified and analyzed in the 2005 Supplemental EIR do not avoid the Project's significant unavoidable impacts on traffic, air quality and cultural resources and/or are not feasible for the specific economic, social, or other considerations set forth below pursuant to CEQA sections 21002, 21081(c). Alternative 1: No Develooment. (DSEIR pp 257-258.). Finding: Infeasible. The 2005 Supplemental EIR updates the No Development Alternative. This alternative would avoid the supplemental traffic, air quality and cultural resources identified in the SEIR, but would not achieve the City's long-established objectives of urbanizing the Fallon Village project site. This alternative also fails to provide needed housing as set forth in the Housing Element of the City's General Plan. This finding is consistent with the City's 1993 and 2002 findings on the No Development Alternative. (See resolutions 53-93 and 40-02, respectively) Alternative 2: No ProiectlDevelooment under Existin2 Sta2e 1 Develooment Plan. (DSEIR pp. 258- 262.) Reso # 222 - 05, adopted 12/6105, Item 6.2 PaQ:e 1 R ofW Finding: Does not avoid the Project's significant unavoidable traffic, air quality and cultural resources impacts. The impacts for this alternative would generally be the same as identified in the 2002 SEIR. Like the Project, this alternative results in unavoidable traffic impacts and air quality impacts from ozone precursors (Resolution 40-02); this alternative also would not avoid the Project's significant cultural resources impact because the Fallon House would be demolished, as with the Project. To the extent that the 2005 Project proposes to develop the AP A, and to increase the number of residences to 3,108 and the amount of commercial, office and other non-residential use to 2,503,175 square feet, this alternative does not meet Project objectives because it retains the AP A as a future study area and does not provide for either the increased residential or non-residential development. Alternative 3: Reduced Proiect Develooment. (DSEIR pp. 262-265 ) Finding: Does not avoid the Project's significant unavoidable traffic, air quality and cultural resources impacts. This alternative reduces the overall level of Project development by 25% to reduce related trip generation; this level of development would reduce but not avoid the Project's significant supplemental traffic impacts. This alternative would reduce project emissions by approximately 25%, but this substantial reduction would not be sufficient to meet air quality thresholds for ozone precursors. This alternative would demolish the Fallon House and thus would not avoid the Project's significant cultural resources impact. This alternative would result in approximately the same number of residences as the 2002 approval and a more modest increase in non-residential development compared to the Project. This alternative does not meet Project objectives because it does not provide for the Project's increased residential and non-residential development. Alternative 4: Offset Central Parkwav. (DSEIR pp. 265-269) Finding: Does not avoid the Project's significant unavoidable traffic, air quality and cultural resources impacts; creates a new significant unavoidable impact. This alternative is a limited focus design alternative. It would reduce the Project biological resources impacts by crossing the central open space corridor at a narrower area further from the ponds on the Jordan property It would not avoid the Project's traffic, air quality or cultural resources impacts, and would create two additional significant traffic impacts as follows: Supplemental Impact ALT 4-1: Project contribution to impacts at Tassajara RoadlDublin Boulevard intersection in the pm peak hour in the 2025 Buildout plus Project scenario. (DSEIR p. 266 ). Mitigation SM-AL T -4.1 would reduce this impact through contribution to planned intersection improvements by payment of the Eastern Dublin Traffic Impact Fee, but not to less than significant. Physical constraints at the intersection and the potential safety hazard created by having four left turn lanes prevent construction of improvements sufficient to reduce the impact to less than significant, therefore, the impact for this alternative would be significant and unavoidable. Supplemental Impact ALT 4-2: Impacts to Upper Loop Road. (DSEIR p. 267) Redirecting traffic through an offset of Central Parkway could overburden the Upper Loop Road. Mitigation SM- ALT-4.2 would reduce this impact to less than significant by requiring four travel lanes on the Upper Loop Road between Fallon Road and Central Parkway as offset. Alternative 5: Industrial Alternative. (DSEIR pp. 269-272.) This is a limited focus alternative that would replace 77 1 acres ofland between 1-580 and the Dublin Boulevard extension with an industrial land use designation rather than commercial and office uses. Finding: Does not avoid the Project's significant unavoidable traffic, air quality and cultural resources impacts. Industrial uses tend to be less traffic intensive than commercial uses, but Reso # 222 - 05. adopted 12/6105, Item 6.2 PaQ:e 19 of 39 not enough to avoid the Project's significant supplemental traffic impacts. Further, any reduced traffic trips would not reduce emissions enough to avoid the Project's air quality impacts related to ozone precursors. This alternative would not avoid the Project's cultural resources impact since it would also result in demolition of the Fallon House. Alternative 6: Jordan Alternative. (DSEIR pp. 272-276) This alternative would reduce the size of the central open space corridor and correspondingly expand the adjacent development areas. The total amount of residential and commercial development would not change, only the location in the open space corridor area. This alternative would require a project sponsor to request and have approved a general and specific plan amendment. Finding: Does not avoid the Project's significant unavoidable traffic, air quality and cultural resources impacts; creates new significant biology and cultural resources impacts. This alternative would create new significant impacts since sensitive biological and cultural resources areas would be developed instead of retained in open space. Supplemental Impact AL T 6-1: Impacts to wetlands, special-status species and habitat. (DSEIR p. 274) Mitigation SM-ALT-6-1 would reduce this impact to less than significant by requiring the developer to prepare a biological mitigation plan prior to approval of any related general or specific plan amendment for approval by the City and state and federal resources agencies. Supplemental Impact ALT 6-2: Impacts to cultural resources. (DSEIR p. 275 ) Mitigation SM- AL T -6-2 would reduce this impact to less than significant by requiring the developer to prepare a detail mitigation plan that identifies the precise location of underground resources and identifies a plan to document and protect the resources in place if feasible, or off-site if on-site is not feasible. Part C: Statement of overriding considerations. 1. General. Pursuant to CEQA Guidelines Section 15093, the City Council of the City of Dublin adopted a Statement of Overriding Considerations for those impacts identified in the Eastern Dublin EIR as significant and unavoidable. (Resolution 53-93, May 10, 1993). The City Council carefully considered each impact in its decision to approve urbanization of Eastern Dublin through approval of the Eastern Dublin General Plan Amendment and Specific Plan project. In 2002, the City Council considered an annexation and prezoning project on the Project site. That project was approved for future development of up to 2,526 dwellings at a variety of densities, up to 1,421,450 square feet of office development, commercial and similar non-residential land uses, a junior high school, elementary schools, parks, utility extensions and open spaces. The City prepared a Supplemental EIR for the 2002 project which identified supplemental impacts that could be mitigated to less than significant. The Supplemental EIR also identified supplemental air quality, biology, noise, and traffic impacts that could not be mitigated to less-than-significant. The City Council adopted a Statement of Overriding Considerations with the original land use approvals for urbanization of Eastern Dublin and with the 2002 approvals on the Project site. (Resolutions 53-93 and 40-02, respectively) Pursuant to a 2002 court decision, the City Council must adopt new overriding considerations for the previously identified unavoidable impacts that apply to the Fallon Village project.! The City Council must also adopt overriding considerations for the supplemental impacts identified in the 1<< . public officials must still go on record and explain specifically why they are approviug the later project despite its significant unavoidable impacts." (emphasis in original) Communitiesfor a Better Environment v California Resources Agency (2002) 103 Cal. App.4th 98. Reso # 222 - 05, adopted 1216105, Item 6.2 PaQ:e 20 of39 2005 Supplemental EIR as significant and unavoidable. The City Council believes that many of the unavoidable environmental effects identified in the Eastern Dublin EIR, the 2002 Supplemental EIR and the 2005 Supplemental EIR will be substantially lessened by mitigation measures adopted with the prior approvals and by the environmental protection measures adopted through the Fallon Village approvals, to be implemented with the development of the project. Even with mitigation, the City Council recognizes that the implementation of the project carries with it unavoidable adverse environmental effects as identified in the prior EIRs and the 2005 Supplemental EIR. The City Council specifically finds that to the extent that the identified adverse or potentially adverse impacts for the project have not been mitigated to acceptable levels, there are specific economic, legal, social, technological, environmental, land use, or other benefits and considerations, as set forth below, that outweigh the significant unavoidable impacts on the environment and support approval of the project. 2. Unavoidable Silmificant Adverse Imoacts from the Eastern Dublin EIR. The following unavoidable significant environmental impacts identified in the Eastern Dublin EIR for future development of Eastern Dublin apply to the Fallon Village project. Land Use Impact 3.1/F. Cumulative Loss of Agricultural and Open Space Lands; Visual Impact 3 81B, Alteration ofRuraVOpen Space Character; Visual Impact 3 8/F, Alteration of Visual Character of Flatlands: Although development has occurred south of the project area, the site is largely undeveloped open space land. Future development of the Fallon Village site will contribute to the cumulative loss of open space land and character Traffic and Circulation Impacts 3.3/B, 3.3/E. 1-580 Freeway, Cumulative Freeway Impacts: While city street and interchange impacts can be mitigated through planned improvements, transportation demand management, the 1-580 Smart Corridor program and other similar measures, mainline freeway impacts continue to be identified as unavoidable, as anticipated in the Eastern Dublin EIR. Traffic and Circulation Impacts 3.31, 3.3/M. Santa Rita Road/I-580 Ramps, Cumulative Dublin Boulevard Impacts: The Fallon Village project will be required to implement all applicable adopted traffic mitigation measures, including contributions to the City's TIP program.

The City Council previously balanced the benefits of the Eastern Dublin project approvals and implementing development against the significant and potentially significant adverse impacts identified in the Eastern Dublin EIR as set forth in Resolution 53-93 In 2002, the City Council balanced those unavoidable impacts as well as the supplemental unavoidable impacts identified in the 2002 SEIR, against its benefits, and determined that the unavoidable impacts were outweighed by the benefits of the 2002 project as set forth in Resolution 40-02. Now, in 2005, the City Council, acting pursuant to CEQA Guidelines section 15093, hereby determines that the unavoidable significant impacts of the Fallon Village project identified in the 2005 Supplemental EIR, and the prior EIRs as applicable to the project, are outweighed by the need for and desire of the City to implement and bring to fruition its long-range planning goals and policies. This long-range planning is reflected in the City's 1993, 2002, and 2005 approvals for Eastern Dublin and the project site, and as set forth in the City's General Plan (as amended), Eastern Dublin Specific Plan (as amended), and Zoning Reso # 222 - 05. adopted 12/6105. Item 6.2 PaQ:e 22 of 19 regulations (as amended). The City has carefully and systematically planned for the incremental development of its eastern lands, and the development that comprises the Fallon Village project. The City Council has considered the public record of proceedings for the Fallon Village project and has determined that approval of the project would implement the City's long-term program-level and development-level planning for Eastern Dublin in general and the Fallon Village project site in particular Consistent with this planning vision for Eastern Dublin, the Fallon Village project provides for development of a mixed use community, but also preserves important visual and biological resources through the central open space corridor and through open space designations on steeper lands in the northerly and easterly portions ofthe project site. The project will provide over 3,108 units of needed housing with diverse densities and building types, as well as maintaining open space on the site. The project will also provide 2,503,175 square feet of office, commercial, light industrial and similar non- residential land uses, which will provide services to and employment opportunities for Dublin residents. Finally, the project will provide a junior high school, elementary schools, parks, utility extensions and open spaces, and will provide land for future development of semi-public uses, all within the City's long- term goals for Eastern Dublin.
