Santa Rita Road at Stoneridge Drive--would degrade to an unacceptable level of service compared to conditions with the proposed project. Similarly, during the future cumulative conditions, this alternative would adversely affect one additional intersection compared to cumulative conditions with the proposed project; namely, the intersection of Johnson Drive at Stoneridge Drive would need additional mitigations beyond that identified for the proposed project. The impacts at both of these intersections, however, can be mitigated to aless-than-significant level. On the other hand, because this alternative would not include a residential component, impacts identified in the EIR related to residents (e.g., exposure to sensitive receptors to TACs, and exposure of persons to, or generation of, noise levels in excess of standards) would not occur. Moreover, as indicated in the EIR, the Existing Specific Plan Alternative would not avoid or substantially lessen the proposed project's significant and unavoidable impacts to aesthetics and visual quality, air quality, and traffic. These impacts would remain significant and unavoidable if the Existing Specific Plan Alternative were adopted by the City. The Existing Specific Plan Alternative is infeasible because it is inconsistent with the objectives of the proposed project to provide a site for a senior continuing care community that will help meet the City's and the surrounding community's expanding need for elderly assisted living opportunities, retain existing auto sales within the City by providing for an auto mall site, and provide for a joint neighborhood park/storm water detention facility. The Existing Specific Plan Alternative is also inconsistent with the objective of the proposed project to acknowledge substantial changes in land use conditions infrastructure improvements and agreements that were unknown at the time the 1989 Specific Plan was adopted. Specifically, this altemative would noh. Reflect changes in surrounding land uses not contemplated in 1989, including cessation of the KaiseNHanson quarry operations, establishment of the Livermore Airport Protection Area, and adoptioNimplementation of the Eastern Dublin Specific Plan to the north and the EI Charro Specific Plan to the east. Reflect changes to the timing, funding, and specific design of major infrastructure improvements since the adoption of the 1989 Specific Plan, including completion of the Arroyo Mocho improvements in 2004, the EI Charro Road Cooperation and funding agreements of 2007, and the City of Dublin's I-580 interchange improvements scheduled to begin in 2008. • Reflect the MOU executed by Pleasanton and the Project Sponsor that now serves as a "roadmap" for the future development of the Staples Ranch site.
