UCSF, San Francisco Mayor Ed Lee, and the Golden State Warriors have reached a preliminary agreement that would establish a proposed Mission Bay Transportation Improvement Fund, could potentially cap the number of large-scale events allowed to be held at the Warriors’ proposed Mission Bay Arena on weeknights that the Giants are also in town, and requires the creation of off-site parking for event goers to the south of the arena.

And as such, UCSF now officially endorses the Warriors’ Mission Bay Arena development.

In addition to the $27 million in upfront funds for transportation and infrastructure improvements already included in the Warriors’ development agreement, the Mission Bay Transportation Improvement Fund would set aside upwards of $10 million per year for traffic mitigations, such as:

Four new light rail cars dedicated to serving the arena and an expanded light rail platform; A Local/Hospital Access Plan designed to keep Fourth and Owens streets clear of event traffic; Increased bus and light rail service before and after arena events, including a quadrupling of service on the T-Third Muni Metro line; Up to 28 traffic control officers deployed before and after games and events (which is more than currently serve Giants games); Enhanced police foot patrols and street cleaning operations on event days; and Studying the feasibility of new or enhanced transportation options, such as dedicated ferry service, for the neighborhood

If initial traffic on weeknights that large arena events overlap with Giants home games exceeds a predetermined threshold, the Warriors will cap future dual events at 12 per year. And the stipulated off-site parking to the south of the arena is expected to be at Pier 70 and the former Western Pacific rail yard adjacent to Pier 80.

UCSF had announced qualified support for the Warriors arena in July, subject to a formal agreement and traffic plan addressing the university’s concerns about traffic, access to the hospitals and overlapping events at nearby AT&T Park.

Neither the California Nurses Association nor the Mission Bay Alliance, both of which oppose the Warriors Arena, have yet to respond. And no official word from the Dogpatch Neighborhood Association with respect to the stipulated parking which will likely increase traffic through their ‘hood.
