SAN LEANDRO GENERAL PLAN UPDATE FINAL EIR <br />CITY OF SAN LEANDRO <br />EXECUTIVE SUMMARY <br />LTS = Less Than Significant S = Significant SU = Significant Unavoidable Impact N/A = Not Applicable <br />2-22 AUGUST 2016 <br />TABLE 2-1 SUMMARY OF IMPACTS AND MITIGATION MEASURES <br />Impact <br />Significance <br />before <br />Mitigation Mitigation Measures <br />Significance <br />after <br />Mitigation <br />intersection is under Caltrans’ jurisdiction, and the <br />implementation and timing of the mitigation measures are not <br />under the City’s control. Consequently, the Cumulative with <br />Proposed Plan impact remains significant and unavoidable. <br /> Warden Avenue/Timothy Drive and Davis Street (#29): The <br />addition of Cumulative with Proposed Plan traffic would cause <br />the intersection level of service to degrade from LOS C to LOS E in <br />the PM peak hour. Therefore, the Cumulative with Proposed Plan <br />impact is considered to be significant. <br />Implementation of the following measures would improve <br />intersection operations during the PM peak hour: <br /> Restripe the three northbound lanes from Timothy Drive to <br />provide an exclusive left-turn lane, a shared left- <br />turn/through/right-turn lane and an exclusive right-turn lane. <br /> Optimize the traffic signal cycle length and splits in conjunction <br />with adaptive traffic control technology. <br />Upon implementation of these measures, intersection operations <br />would improve to LOS D during the PM peak hour. This <br />intersection is under Caltrans’ jurisdiction, and the <br />implementation and timing of the mitigation measures are not <br />under the City’s control. Consequently, the Cumulative with <br />Proposed Plan impact remains significant and unavoidable. <br /> Doolittle Drive and Davis Street (#30): The addition of Cumulative <br />with Proposed Plan traffic would cause the intersection level of <br />service to degrade from LOS C to LOS F in the PM peak hour. <br />Therefore, the Cumulative with Proposed Plan impact is <br />considered to be significant. <br />Implementation of the following measures would improve <br />intersection operations during the PM peak hour: <br /> Restripe the four westbound lanes from Davis Street to <br />provide one exclusive left-turn lane, one exclusive through <br />lane and two exclusive right-turn lanes. <br /> Restrict westbound right turns on red to reduce conflict <br />between right-turning vehicles in the two exclusive right-turn
