If I ever, ever, which looks like not at all on my current path, write a history of urban renewal from the neighborhood perspective in Washington, DC I will have to include the District of Columbia Redevelopment Agency (RLA). According to the US Government Organization Manual the RLA was:
Created by act of Aug 2, 1946 (60 Stat. 790), to provide for replanning, rebuilding, and rehabilitation of slum and blighted areas in the District of Columbia. The District of Columbia Self-Government and Governmental Reorganization Act of Dec 24, 1973 (87 Stat. 774), established the agency as an instrumentality of the District of Columbia government, effective July 1, 1974
A post war agency to deal with slums turned into something that helped with the destruction of SW. Which who knows, may have needed destroying in parts, but not to the extent it did with the SW Urban renewal in the 50s and 60s.
