Treasure Island, located in San Francisco, California. The 400-acre (1.5-square-km) man-made island was built in the middle of San Francisco Bay for the 1939 Golden Gate International Expositione.
Under a new proposal, Treasure Island -- along with its neighbor Yerba Buena Island -- will become one of the most environmentally friendly developments in the United States when ground is broken in 2009.
Treasure Island project will be a test bed for eco-friendly urban ideas. Some of the proposed green features include LEED-certified buildings, the elimination of storm water runoff, alternative forms of water treatment including artificial wetlands called Living Machines and a transit system that favors clean air vehicles over fossil-fuel chugging cars.
A 20-acre city-operated organic farm is planned in walking distance from the city center and will supply the projected 13,500 residents with locally produced foods. Solar and wind-farm power will provide energy; and by 2020, solar panels will cover 70 percent of rooftop space and will provide about 30 million kilowatt hours of electricity annually.
Treasure Island is now green-friendly.
