2,560 trips in the evening peak hour. These estimates may be reduced if the TDM program proves successful. (b) Traffic impacts within the City of Santa Aha may be accommodated within an estimated near-term cumulative setting with implementation of select area traffic improvements that have been identified for the "ultimate build-out" condition. These improvements include completion of Columbine Avenue across the entire site frontage with a primary cross-section, completion of master plan improvements along the Project's Main Street frontage, minor modification and restriping on MacArthur Boulevard under Route 55 to maintain a continuous six lane cross-section, and localized lane improvements at six key area intersections. Phase I traffic improvements would ensure LOS D peak hour operating conditions at all locations generally west of Route 55, except the Main/MacArthur intersection. (c) Future and near term operating conditions at key intersections along the Red Hill corridor in the City of Irvine would be adverse to varying degrees without the impacts of the Project and with improvements beyond the programs initiated by the City of Irvine. B. Findings. (1) Changes or alterations have been required in, or incorporated into, the Project which avoid or substantialy lessen the significant environmental effect as identified in the EIR. (2) Other changes or alterations are within the responsibility and jurisdiction of Caltrans, FHA and the City of Irvine. Such changes have been adopted by such other agencies or can and should be adopted by such other agencies. (3) Specific economic, social or other considerations make infeasible mitigation measures not identified in the EIR Or the project alternatives identified in the EIR and set forth in Section 4 below. (4), Any remaining unavoidable adverse impacts on the environment are considered acceptable when balanced against the facts set forth in the Statement of Overriding Considerations. -20-
