Treasure Island

San Francisco, California, USA

Treasure Island’s development vision captures the extraordinary beauty and culture of San Francisco and the bay unlike any other place in the Bay Area. In the 1930’s Treasure Island was created as the future San Francisco International airport. It has now been transformed into a sustainable integrated-use district for San Francisco. Centered in the middle of the San Francisco Bay, the island is a 10 minute ferry ride door-to-door from home to San Francisco’s financial district. The island is also attached to the Bay Bridge, connecting the island to both east and west Bay Area cities. Treasure Island is a high density vertically integrated mixed-use development, utilizing sustainability and Whole Living principles. It is planned for a resident population of approximately 20,000 residents and a regional attraction. It includes 14 high-rise towers up to 65 stories. It is established as a one-of-a kind district that is compact, diverse and walkable.  The island is enhanced by a ferry terminal connecting the island to multiple locations throughout the Bay Area and is established as an integrated work, live, entertainment and commercial district, and a regional hub for art and culture, San Francisco’s historic memorabilia, regional recreation, including, boat marinas, public art, wildlife and wetlands restoration, an organic demonstration farm and numerous luxury hotels and spas.

The focus of Treasure Island is to capture the beauty of the site and to establish a world-class sustainable community for the City of San Francisco. The goal of the community is to create a dense fully integrated district with easy public transportation to the urban core. Applying a compact, diverse and walkable urban strategy that is sustainable by its very nature. This new district employs applications of solar and wind generating and an urban plan with a diagonal grid meant to protect public spaces from the inhospitable Pacific Ocean winds and to optimize solar exposure. Other sustainable development strategies include a electric public transit, an organic farm, anaerobic waste management, water recycling, energy efficiency measures and wind turbines.

“…the Treasure Island neighborhood will be distinctly San Franciscan; compact, walk able and forward thinking…

…a strong emphasis will be placed on the Smart City concept, establishing sustainability and the creation of a regional destination…

…the community plan has wind turbines along the shore, and streets mapped to deflect that wind. Towers have photovoltaic panels to generate electricity for the island; so would a glass canopy atop the open-air retail zone near the ferry. Most ambitious of all, 90 percent of the housing is clustered within a 10-minute walk to the ferry….”
