A series of events centered on the Works Progress Administration (WPA) Model of San Francisco will bring into focus spatial and social change in the city’s neighborhoods since the 1930s. On March 3, a talk by Gray Brechin and Stella Lochman will take place at the SF History Days. Titled, “The WPA City Model: Its Return to the Public and the Take Part Project,” the talk is scheduled at 11:45 am at the Old U.S. Mint. More than 100 events related to the SF WPA model will take place under the auspices of Public Knowledge and Take Part, the San Francisco Public Library’s partnership with the San Francisco Museum of Modern Art. The 1,500 sq. ft. model of San Francisco built by the WPA is on display at all 29 branches of the San Francisco Public Library. How the city’s neighborhoods have changed since the 1930s is the focus of the “Reading the Model at Main,” a Take Part event scheduled on February 16 at the Skylight Galley at Main Library. The event will bring together residents and special guests for a conversation about the city’s past and its future development. “Modeling the City: Building on Toxic Land” is another Take Part event focused on the environmental threats that have emerged as San Francisco has expanded over time.
