Crissy Field presented the challenge of the “restoration of a culturally significant grass military airfield” overlapping much of the same landscape as the tidal marsh, effecting “the ability to restore the marsh to the pre-military configuration, to an idealized ‘natural’ condition." In order to create the new site, 87,000 tons of hazardous materials were removed from the site itself and the tidal wetlands were redesigned to simulate the wetlands that existed before the military appropriated the site and used the area as a dump and landfill location. The site provides great views of the San Francisco bay area, Alcatraz and the Golden Gate Bridge.
