to provide two left -turn lanes, one through lane and one shared -through -right lane on the southbound approach (as well as bike lanes in both directions in accordance with the San Leandro Bicycle and Pedestrian Master Plan). With such widening, the southbound left -turn queue could be accommodated within the storage capacity of the two left turn lanes, and upstream traffic operations along Merced Street would not be adversely affected. The mitigation measure requires the project sponsors to contribute fair -share funds towards this improvement. (MM TR -1.2) The left -turn lane required for the new signalized driveway along Marina Boulevard could encroach into Caltrans right-of-way. It is uncertain if an encroachment permit can be acquired, and therefore the City cannot guarantee that this mitigation measure will be fully implemented. As such, impacts to the Marina Boulevard/Merced Street intersection would be significant and unavoidable. Additionally, widening Merced Street would require the acquisition of additional right-of-way. Acquiring this additional right-of-way cannot be guaranteed due to the presence and potential impacts to existing businesses along Merced Street. As such, impacts to the Republic Avenue/ Merced Street intersection would be significant and unavoidable. Traffic Impacts - Cumulative (2035) plus Phase 1 plus Mixed Use Retail Development When added to projected cumulative traffic levels by year 2035, traffic associated with development of Phase 1 of the Kaiser Medical Center together with traffic from the mixed-use retail development would cause several 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 above, there is additional mitigation needed to address the contribution to cumulative traffic impacts associated with Phase 1 of the Kaiser Medical Center together with traffic from the mixed-use retail development. 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. Intersection - Mitigation Measure Limits on Implementation' Location Davis Street/ Mitigation of this traffic impact requires the westbound lanes to Implementation of this Doolittle Drive be re -striped to provide one left turn lane, one through lane, and mitigation measure would two right -turn lanes. The mitigation measure requires the project require an encroachment sponsors to contribute fair -share funds towards this permit from Caltrans. ' The use of italics font under the column "Limits on Implementation" indicates that the recommended mitigation measures may not be feasible due to required right-of-way acquisition and/or obtaining permits from other agencies, such that the impact may remain significant and unavoidable. If these limitations on implementation can be overcome (i.e., should right-of-way acquisition be found to be feasible or if permits can be obtained from other agencies), these mitigation measures would be capable of reducing impacts to levels of less than significant.
