Treasure Island

  • Sustainable redevelopment of 400ac man-made island in San Francisco Bay.
  • Received 2006 San Francisco Design Honors Urban Design Award.

Taking its name from the traces of gold rumoured to line the dredged river delta mud that helped to create it, Treasure Island in San Francisco Bay will be the home of a highly-sustainable urban community.

The island was developed in the 1930s as a seaplane depot and was planned as the city’s airport. From the onset of World War II, the island was used as a naval base until 1995.

Following its decommissioning, a redevelopment plan emerged from hundreds of planning sessions and public meetings. The plan envisioned a 6,000-unit residential and mixed-use development that will draw more than 50% of its energy from renewable sources.

Arup’s sustainability consultants are advising on transportation planning, site infrastructure, carbon management, and sustainability strategies.

In addition to widespread use of solar power, Arup has recommended on-island power and waste water treatment, stormwater attenuation, wetlands treatment and grey water reclamation, as well as alternative transport options for residents and tourists.

The current timetable is that the first residents will begin taking occupancy in 2013 and 2014.
