Golden State Warriors Arena

Assisting the Lead Agency with the Warriors' San Francisco Arena Project

On July 18, 2016, Judge Wong of the San Francisco Superior Court delivered a decisive victory to the respondents and real parties in interest in the litigation concerning the proposed Golden State Warriors arena in Mission Bay Alliance v. Office of Community Investment and Infrastructure (OCII). Judge Wong’s decision was subsequently upheld by the First District Court of Appeal in a published decision: Mission Bay Alliance v. Office of Community Investment & Infrastructure (2016) 6 Cal. App. 5th 160. Shortly thereafter, the California Supreme Court denied the Petitioner’s Petition for Review and multiple requests for depublication.

For years, the Warriors had been planning to relocate to San Francisco from Oakland. The Project involved constructing a multi-purpose arena and mixed-use development, including office, retail, and open space, on an 11-acre site in the Mission Bay South Redevelopment Plan area. San Francisco celebrated the grand opening of the arena (now known as the Chase Center) on September 6, 2019.

In April 2015, the Governor certified the Project as an Environmental Leadership Development Project under AB 900. A subsequent environmental impact report was prepared for the Project, tiering from the 1998 Mission Bay EIR. Multiple lawsuits were filed against the Project in various jurisdictions by Mission Bay Alliance. After consolidating two of the actions, the trial court found that the Project complied with CEQA and that OCII, acting as the lead agency, did not abuse its discretion by approving the Project. The court also upheld various related actions taken by the City and County of San Francisco concerning the Project. The subsequent appeal and Petition For Review were also resolved in favor of the City.

Tina Thomas and Chris Butcher represented OCII throughout the administrative process at the trial court, and the appellate court and continues to represent the agency.

The arena has been named the Chase Center and it is operational. For more information, see
