Mitigation Measure 4.N-1e is revised to read as follows:

Mitigation Measure 4.N-1e: Prior to issuance of the first building occupancy permit for new development within the Project Site other than relocation or improvement of an existing use, The following physical improvements shall, to the extent permitted by agencies with jurisdiction over this intersection, be constructed and accepted for public maintenance prior to issuance of occupancy permits for any site-specific development that would (1) result in reducing the intersection to below the acceptable LOS standard, or (2) contribute additional traffic to the intersection if it is already operating below the acceptable LOS standard. A a signal phase shall be provided for the westbound right approach at the intersection of Tunnel Avenue & Bayshore Boulevard, and signal timing settings for the AM and PM peak periods shall be modified by changing the southbound left phase from the existing permitted to protected phase, and shifting 20 seconds of green time from the northbound and southbound movements to each of the southbound left and westbound right phases.

Mitigation Measure 4.N-1f is revised to read as follows:

Mitigation Measure 4.N-1f: Prior to issuance of the building occupancy permit for an arena within the Project Site, the arena operator shall develop a Transportation Management Plan (TMP) for coordination with the San Francisco Municipal Transportation Agency (SFMTA), the San Francisco Police Department, and the City of Brisbane, developing incentives to increase transit ridership to the arena, and deploying traffic control officers at the unsignalized intersection of Blanken Avenue and Tunnel Avenue to approximate traffic control with traffic signals of LOS C. Prior to issuance of a building occupancy permit for an arena within the Project Site, the City of Brisbane shall complete its review and approve the proposed TMP.

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

Mitigation Measure 4.N-3a:²⁰ Prior to issuance of the first building occupancy permit for new development other than improvement or relocation of an existing use within the Project Site, In addition to the improvements required by Mitigation Measure 4.N-1a (which addressed Existing Plus Project conditions) shall be supplemented the following physical improvements shall be constructed and accepted for public maintenance to account for cumulative traffic conditions prior to issuance of occupancy permits for any site-specific development that would (1) result in reducing the intersection to below the acceptable

²⁰Mitigation Measure 4.N-1a 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-1a is implemented.
