Treasure Island is one of the largest development sites in the San Francisco Bay Area. The master plan, including 6,000 new residential homes, mixed-use space for retail and commercial ventures, and over 300 acres of public parks and open space, has been designed to create a vibrant, walkable community. The residential plan includes a diversity of homes from single-family townhomes to mid-rise and high-rise towers, of which 30 percent will be affordable housing. Plans for a new ferry quay and terminal will provide direct access to and from San Francisco. This transformation of the former Naval Base into a new San Francisco community is anticipated to become one of the foremost transit-oriented sustainable developments in the United States.
