Traffic Impacts - Cumulative(2035) plus Project Buildout When added to projected cumulative traffic levels by year 2035, 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. Mitigation: In addition to the improvements identified in MM TR -1.1 through MM TR -1.3 and MM TR -9.1 through TR -9.7 above, there is additional mitigation needed to address the project's total contribution to cumulative traffic impacts. The following table provides a summary of the affected intersections, the mitigation measures required, and a conclusion as to whether these measures can be implemented by the City to reduce traffic impacts. Since each of these mitigation measures would either encroach into Caltrans right-of-way and require an encroachments permit, or would require the acquisition of additional right-of-way, it is uncertain whether these mitigation measures can be implemented. Since the City cannot guarantee that these mitigation measures will be implemented, these cumulative traffic impacts would be significant and unavoidable. Intersection - Location Mitigation Measure Davis Street/ Mitigation of this traffic impact requires re -striping the Phillips Lane 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. (MM TR -13.1) Limits on Implementation Implementation of this mitigation measure would require an encroachment permit from Caltrans. Marina Mitigation of this cumulative traffic impact requires increasing be accommodated by Boulevard/ roadway capacity by adding a third left -turn lane on the reducing the bike lane and Merced Street westbound approach to Marina Boulevard/Merced Street sidewalk right-of-way and intersection. The mitigation measure requires the project reconfiguring the sponsors to contribute fair -share funds towards this channeling island. I-880 Mitigating this impact would require the widening of I-880. The Widening the I-880 freeway required TDM program (MMAQ-2.1) would reduce project is outside the purview of the trips through increased use of alternative modes of City of San Leandro. transportation and would help to reduce trips along 1-880, but not to a level that would reduce project impacts to less than significant.
