increase in the amount of vehicle traffic on I-880 during the AM and PM peak hours of more than one percent of the freeway segment's design capacity and also result in queuing impacts to the southbound 1-880 off -ramp at Marina Boulevard during the Saturday peak period. Mitigating this impact would require the widening of 1-880. The required TDM program (MM AQ -2.1) would reduce project trips through increased use of alternative modes of transportation and would help to reduce trips along 1-880, but not to a level that would reduce project impacts to less than significant. Widening the 1-880 freeway is outside the purview of the City of San Leandro and within the responsibility and jurisdiction of another agency. As such, the City cannot guarantee implementation of the Mitigation Measure, and this impact would be considered significant and unavoidable for purposes of the CEQA analysis. This potentially unavoidable significant impact is overridden as set forth below in the Statement of Overriding Considerations. e. Traffic Impacts - Cumulative (2030) plus Project Buildout. When added to projected cumulative traffic levels by year 2030, traffic associated with buildout of the entire project (Phase 1 of the Kaiser Medical Center, the mixed-use retail development, and Medical Center buildout) would cause several additional intersections to degrade to substandard levels of service. Implementation of Mitigation Measures TR -1.1 to TR -1.4, and TR -9.1 to TR -9.7 (all described above) would reduce the impacts under Cumulative plus Kaiser Medical Center Build -Out plus Mixed -Use Retail Development conditions except at the Davis Street/Phillips Lane, Marina Boulevard/Merced Street, and Marina Boulevard/Wayne Avenue intersections. (1) Project -generated traffic would adversely affect the Davis Street/Phillips Lane intersection during the PM peak hour, resulting in a substandard level of service. The intersection of Davis Street/Phillips Lane would deteriorate from LOS E to LOS F during the PM peak hour with an increase in V/C of 0.05. Therefore, the project impacts are significant. Mitigation Measure TR -13.1 requires re -striping the westbound approach lanes at the Davis Street/Phillips Lane intersection such that the westbound shared through -right lane shall be converted to an exclusive through lane to provide one left -turn lane, two through lanes, and one right -turn lane. The mitigation measure requires the project sponsors to contribute fair -share funds towards this improvement. However, implementation of this mitigation measure would require an encroachment permit from Caltrans. As such, approval of this mitigation is exclusively within the responsibility and jurisdiction of Caltrans and the City, as lead agency for the Project, cannot guarantee Caltrans' approval. While the City is requiring as a condition of approval that Kaiser seek an encroachment permit from Caltrans, because the City cannot guarantee that this mitigation measure will be fully implemented and no other feasible mitigation exists, this impact is considered significant and unavoidable for purposes of the CEQA analysis. This potentially unavoidable significant impact is overridden as set forth below in the Statement of Overriding Considerations. -15-
