This alternative differs from the preferred project in that it would not include the senior continuing care community, it does not specify the development of an auto mall, does not include the joint neighborhood park/storm water detention facility or ice center and would allow Stoneridge Drive to be widened to six lanes if traffic demand warranted such widening. Finding. Infeasible The environmental impacts of the Existing Specific Plan Alternative would have slightly greater impacts than the preferred project. This alternative would result in substantially more traffic than projected for the preferred project and cause additional significant impacts not identified for the preferred project. In particular: Air: This alternative would result in considerably more vehicular trips than the preferred project (roughly 60% more), 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 preferred 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 preferred project, there may be a slightly greater potential for an accidental release of hazardous materials. Nevertheless, this greater potential for accidental releases would be subject to mitigation following the same procedures, protocols, and regulations that were identified for the preferred project. Noise: The Existing Specific Plan Alternative would greatly increase the number of daily trips compared to the preferred project and would result in significant noise level increases. Traffic: Overall trip generation would increase substantially with the' Existing Specific Plan Alternative, compared to the preferred project. This alternative would adversely affect one additional intersection compared to cumulative conditions with the preferred project; namely, the intersection of Johnson Drive at Stoneridge Drive, although the impacts at this intersection can be mitigated to a less -than -significant level. On the other hand, because this alternative would not include a residential component, impacts identified in the SEIR and 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 SEIR and EIR, the Existing Specific Plan Alternative would not avoid or substantially lessen the preferred project's significant and unavoidable impacts to aesthetics and visual quality, air quality, noise and traffic.
