Perched on the edge of San Francisco Bay, the Hunters Point Shipyard was an important naval manufacturing center for the WWI and WWII war efforts. The abandoned shipyard and Candlestick Point were combined into a new, mixed-use residential, retail and light industry development—the largest in San Francisco since WWII. Thomas Balsley Associates collaborated with urban planners IBI Group in developing an innovative urban plan whose parks and open spaces exploit the site’s extraordinarily diverse waterfront and views as well as its rich maritime heritage. The plan combines the proposed Forty-Niners football stadium within the new mixed-use community with a sustainable system of smart streets, bikeways and diverse parks, including California’s first urban state park, redesigned to function as the front lawn to San Francisco’s Bayview and Hunters Point Community. A lively network of neighborhood parks, plazas, linear boulevard parks, roof deck recreation areas, and a continuous waterfront park trail and bikeway system knits the spaces together and connects the upland community to its new shipyard neighbors and the extraordinary bay environment. The state park’s grassland and natural shoreline has been retooled into a landscape of the highest standards of environmental and social sustainability.
