Greendale is a village in Milwaukee County, Wisconsin, United States. The population was 14,405 at the 2000 census.
Greendale was settled in 1938 as a public cooperative community in the New Deal Era. Construction of the new town would create jobs and thus help stimulate the national economic recovery following the Great Depression.
Greendale, which provided good housing at reasonable rents for moderate income urban families, was one of three "greenbelt" towns planned beginning in 1935 under the direction of Rexford Guy Tugwell, head of the United States Resettlement Administration, under authority of the Emergency Relief Appropriation Act. The two other greenbelt towns are Greenbelt, Maryland (near Washington, D.C.) and Greenhills, Ohio (near Cincinnati). The greenbelt towns not only provided work and affordable housing, but also served as a laboratory for experiments in innovative urban planning. Greendale's plan was designed between 1936 and 1937 by a staff headed by Joseph Crane, Elbert Peets, Harry Bentley, and Walter C. Thomas for a site that had formerly consisted of 3,400 acres (14 km2) of farmland.
