For the first time since 1942, the entire immense 42 by 38 foot WPA built San Francisco Model can be seen assembled virtually. Digitally knitting together all 158 separate pieces with over 6,000 blocks gives the viewer a sense of the extraordinary accomplishment the model represents. Recently recovered after decades of dusty storage, [...] it is a 42 by 38 foot wooden replica of the city of San Francisco as it was in 1940 in 158 pieces at a scale of 1 inch to 100 feet. The pieces contain about 6,000 removable city blocks.
The model was built by The Works Progress Administration in the late 1930's, under the New Deal. It was first displayed in sections in the Golden Gate International Exposition on Treasure Island in San Francisco Bay in 1939. In 1940-1942 it was displayed in San Francisco City Hall. The model was used as an urban planning tool by San Francisco city agencies and departments through the 1960's. In 1968, the downtown portion of the model became a research and planning tool in the Environmental Simulation Laboratory in the College of Environmental Design at UC Berkeley. The model has not been on public view, in its entirety, since 1942. [...]
