Treasure Island

San Francisco, California, USA

Treasure Island is the most unique redevelopment site in San Francisco. Centered in the middle of the San Francisco Bay, it is 10 minutes by Ferry from downtown San Francisco and attached to the Bay Bridge to both the east and west bay cities.  Treasure Island is a high density vertically integrated mixed-use development utilizing Smart City concepts, and including 14 high-rise towers up to 65 stories.  The island also is enhanced by a ferry terminal, multiple public transportation options, retail streets, boat marinas, public art, a region park, an organic demonstration farm, and multiple luxury hotels and spas.

The island comprises of 500 acres and captures the best views in the San Francisco Bay Area with stunning downtown silhouettes and uninterrupted views of the Golden Gate Bridge.  The majority of the island is man-made with all sides of the island with easy access to the waterfront.

The focus of Treasure Island is to not only capture the beauty of the site but to establish a model neighborhood for the City of San Francisco.   The goal of the community is to create a dense fully integrated and walk able community with easy public transportation to the urban core of the city. Most importantly Treasure Island is to establish as an environmentally sustainable community through the use of Smart City planning, wind, solar, water conservation, transit oriented and green building concepts.

The community will have approximately 20,000 residents and will be a regional attraction.  Emphasis will be placed on diversity of product, its distinctly San Franciscan in character, and extensive access to downtown, open space, public art, and the waterfront.

Applying an urban strategy that is sustainable by its very nature, this project employs inventive Smart City applications of solar and wind patterns generating an urban plan with a diagonal grid meant to protect public spaces from inhospitable Pacific Ocean winds and to optimize solar exposure. Other sustainable development strategies include a public transit oriented uses, organic farm, water conservation, waste management, energy efficiency measures, wind turbines, and the carefully chosen location of open spaces as reconstructed wetlands.

The master plan community takes advantage of limited access to the island to allow a balance between open space and a dense urban fabric. It also has the necessary height and San Francisco character to serve as one of the last new neighborhoods for the City. The orientation of the tall buildings at the end of open spaces and streets provides a visual terminus and concentrated development at the ferry stop. Rather than cluster the towers, this separation allows light and air to flow between them.

President, LENNAR Urban

“…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….”
