NOTE: starting/ending dates of eras are often approximate (e.g., "Progressive Era") and should be interpreted as rough outlines of overlapping historical eras.

  • notable new towns and projects (including adaptive reuse) in gray shading
  • Environmental planning and related themes (sustainability, ecology, climate change, land conservation, resource management, etc.) noted in the rightmost column ("eco"). This is a potentially broad category, and I have likely omitted important key entries. Please email me additions (see above.)

1949

Housing Act of 1949 (Wagner-Ellender-Taft Bill). Aimed to provide about 800,000 units to be constructed over a period of six years. First U.S. comprehensive housing legislation. Title I: federal funding for slum clearance; Title II: Federal Housing Administration (FHA) mortgage insurance; Title III: federal funding for public housing. "The law was the product of seven years of bitter legislative stalemate and a shotgun wedding between enemy lobbying groups. It set lofty goals—to eliminate slums and blighted areas and provide a decent home for every American family—but provided only the limited mechanisms of public housing and urban renewal to meet them" (von Hoffman, Alexander. 2000. "A study in contradictions: The origins and legacy of the housing act of 1949." Housing Policy Debate 11 (2):299).
