Treasure Island Milestone: First Major Transfer of Property to City of San Francisco
More than half of the adjoining Treasure and Yerba Buena islands have been turned over from the military to the city of San Francisco. Treasure Island consists of 403 acres and Yerba Buena Island consists of 147 acres. It is the first major ownership transfer that could eventually lead to thousands of new homes, businesses and open space on the former Navy sites.
The U.S. Navy conveyed about 310 acres on the islands (including 222 acres on Treasure Island and 88.5 acres on Yerb Buena Island) and 507 acres of submerged land surrounding the islands to the city on May 29, 2015. In a press release, Mayor Edwin Lee called it, “…A major milestone in the redevelopment and revitalization of Treasure Island. ..We’re eager to transform this former naval base into a vibrant community. “
The transfer included structures and land that the Navy had cleaned up by removing toxic chemicals that were a legacy of its military use. In an area at Yerba Buena, lead-contaminated soil was removed and disposed off-site. The California Department of Toxic Substances Control (DTSC) imposed a land-use covenant for the remaining lead-contaminated soil under buildings and hardscape. The covenant details the procedures that must be followed if the buildings and hardscapes are removed.
More land transfers will occur over the next several years as redevelopment progresses.
