An Expanding Vision for San Francisco's Treasure Island

San Francisco is starved for ideas for ways to meet growing demand for housing, and skyrocketing prices. Here's a big idea: how about building space for some 20,000 new residents on Treasure Island, located in the middle of the bay?

"San Francisco officials are moving ahead with plans to expand the city’s sleepy Treasure Island district into a lively residential enclave and tourist destination," reports Antonio Pacheco. In a car, Treasure Island is only accessible by the Bay Bridge and the adjacent Yerba Buena Island, but that isn't stopping city officials from expanding its vision for the island's future.

The city recently revealed plans to add a bevy of cultural institutions and up to 20,000 residents to the man-made island, which sits in the San Francisco Bay halfway between San Francisco and Oakland. Landscape architects CMG have developed an arts-focused master plan for the island in conjunction with urban and architectural master plans developed by SOM and Perkins + Will. 

In all, the new plan could enable as many as 8,500 new residential units and as much 550,000 square feet of commercial space.
