File Number: 14-577 only effective at roads in which cars travel at high speeds, and the speed limit in this area is low; thus, this solution would not be effective. Therefore, no feasible mitigation measures are available and this impact would be significant and unavoidable. Transportation and Traffic TRAF-2A. Significant. Although Mitigation Measures TRAF-2 would mitigate the impacts related to the reduction of level of service to an acceptable level on the 1-880 northbound segment north of Davis Street, the mitigation measures are not considered feasible due to cost and right-of-way constraints associated with widening 1-880. Further, the effectiveness of a shuttle service in reducing the number of Project trips cannot be adequately quantified. As such, this impact would remain significant and unavoidable. TRAF-213. Significant. Mitigation Measures TRAF-213.1 and TRAF-213.2 would involve widening Doolittle Drive and providing shuttle service operating between the Project site and key locations such as the San Leandro and Coliseum BART stations and Oakland International Airport to reduce the V/C ratio (volume/capacity ratio) on the northbound segment of Doolittle Drive, which would result in an acceptable Level Of Service (LOS) under Year 2020 and 2035 conditions. While these measures would improve the level of service and mitigate the impact to less than significant, feasibility of these measures is uncertain due to right-of-way constraints along this corridor. Additionally, the shuttle service, though likely to reduce impacts, could not be quantified. As such, this impact would remain significant and unavoidable. TRAF-713. Significant. Additional traffic associated with the Project would cause 1-880 southbound ramps and Marina Boulevard (#14) to reduce to LOS E during both weekday AM and Saturday peak hours under Near -Term Cumulative Conditions. While Mitigation Measures TRAF-713.1 and TRAF-7B.2 would improve level of service at this intersection, this ramp is under Caltrans jurisdiction; therefore, implementation and timing of these mitigation measures would not be within the City's jurisdiction and the impact would remain significant and unavoidable. TRAF-7C. Significant. The Project would cause operations at the intersection of San Leandro Boulevard and Marina Boulevard (#18) to reduce from LOS D to LOS E in the AM peak hour and would add to the unacceptable LOS F in the PM peak hour and cause the V/C ratio to increase by 0.07. While Mitigation Measures TRAF-7C.1 and TRAF-7C.2 are identified in the Kaiser Permanente San Leandro Medical Center/Mixed Use Retail Development Project EIR and would fully mitigate the Near -Term cumulative impact during the AM and PM peak hours, the available right-of-way on the northbound approach would not be sufficient to accommodate the two left -turn lanes, one through lane, and one shared through -right turn lane, as well as a bike lane. Therefore, this impact would remain significant and unavoidable. TRAF-71. Significant. The Project would case the operations at the intersection of 1-880 southbound ramps and Marina Boulevard (#14) to reduce from LOS D to LOS E in the AM peak hour; and would reduce the level of service from LOS E to LOS F in the weekday PM and Saturday peak hours and cause the V/C ratios to increase by 0.10 during both periods, which is higher than the 0.05 allowed by the City. While Mitigation Measure TRAF-71 would lessen impacts, this ramp intersection is under Caltrans jurisdiction and the implementation and timing of this mitigation measure are not under City control. As such, this impact would remain significant and unavoidable. TRAF-7J. Significant. The Project would add to the Long -Term Cumulative No Project City of San Leandro Page 5 Printed on 1120/2015
