Residential, but this area would be developed with a portion of the community park. No residential units would be constructed under this alternative. The remaining 122.5 acres of undeveloped land in unincorporated Alameda County would be annexed into the City. The land use designations for this area, according to the 1989 Specific Plan, include Service Commercial and Light Industrial, Retail and Service Commercial, and Community Park. This alternative differs from the proposed project in that it would not include the senior continuing care community, it does not specify the development of an auto mall, and does not include the joint neighborhood park/storm water detention facility. Finding: Infeasible As indicated in the EIR, the environmental impacts of the Existing Specific Plan Alternative would have slightly greater impacts than the proposed project. This alternative would result in substantially more traffic than projected for the proposed project and cause additional significant impacts not identified for the proposed project. In particular: Air: This alternative would result in considerably more vehicular trips than the proposed project (roughly twice as much), and exceed the BAAQMD thresholds for criteria air pollutants. The resultant emissions would be a significant and unavoidable air quality impact, with air emissions substantially greater than predicted for the proposed project. Hazards: Because the Existing Specific Plan Alternative would have the potential to accommodate more retail, service commercial, and light industrial uses, which typically involve greater amounts of hazardous materials and waste, than the proposed project, there may be a slightly greater potential for an accidental release of hazardous materials. Nevertheless, this greater potential for accidental releases would be mitigable following the same procedures, protocols, and regulations that were identified for the proposed project. Noise: The Existing Specific Plan Alternative would result in almost double the number of daily trips as the proposed project. The Existing Specific Plan Alternative would increase noise levels above existing noise levels by a maximum of 8 dBA along EI Charro Road, and would result in significant noise level increases. The Existing Specific Plan Alternative's contribution to this increase would be 3.6 dBA over future noise levels without the project. This would be a new significant impact of this alternative. Traffic: Overall trip generation would increase substantially with the Existing Speck Plan Alternative.
