LOS standard, or (2) contribute additional traffic to the intersection if it is already operating below the acceptable LOS standard. Thus, the full extent of improvements shall include the following:

The eastbound approach at the signalized intersection of Geneva Avenue & Bayshore Boulevard shall be restriped to create one additional through lane and to modify one of the existing two right-turn lanes to become a shared through/right-turn lane. In addition, the southbound approach shall be restriped to provide an additional exclusive left-turn pocket. Finally, the northbound approach shall be restriped to provide two additional lanes: an additional left-turn pocket and an added right-turn lane.

As a condition of approval for the first discretionary action taken for development within the Project Site, the applicant shall be required to initiate a corridor plan for Bayshore Boulevard in cooperation with Daly City and San Francisco to determine the suite of improvements necessary to resolve long-term cumulative traffic issues along the corridor. Because the effectiveness of such a corridor plan would necessitate participation by Daly City and San Francisco in recognition of increases in traffic along the Bayshore corridor that will be generated by future development within those two jurisdictions, Brisbane will also make its best efforts to assist the developer in securing the agreement of Daly City and San Francisco to participate in the corridor study and its implementation.

Mitigation Measure 4.N-3b is revised to read as follows:

Mitigation Measure 4.N-3b:²¹ At the signalized intersection of Old County Road & Bayshore Boulevard,²² the eastbound approach shall be

²¹Mitigation Measure 4.N-1b provides for mitigation of Project Site development-related impacts in the Existing plus Project condition, while this mitigation measure provides for mitigation in the Cumulative With Project condition. This mitigation measure is based on needed modification to the existing, baseline configuration of the intersection, and does not assume that Mitigation Measure 4.N-1b is implemented.
²²Existing Bayshore Boulevard at Old County Road is approximately 80 feet wide and includes two through lanes for each direction and a median. Dedicated right-turn yield lanes are currently provided at all four approaches.
