In 1917, in Buchanan v. Warley, the U.S. Supreme Court held the Louisville [housing segregation, block-by-city-block] ordinance unconstitutional (p.101)...[Yet] during the Depression the federal government acted as if Buchanan did not exist when it set up at least seven towns-- Richland, Washington; Boulder City, Nevada; Norris, Tennessee; Greendale, Wisconsin; Greenhills, Ohio; Arthurdale, West Virginia; and Greenbelt, Maryland-- that explicitly kept out African Americans (p.103)... progress [toward integration] has been real but uneven (p.416)... America's seven FDR towns, all sundown from the start, exemplify this unevenness. Greenbelt, Maryland is now 41% black, while Greenhills, Ohio, is 2.6% black (p.515).
Eager for the new town to be accepted not only by these few but by the entire metropolitan community, federal officials dedicated themselves to abiding by 'community standards' in their new town. As a result, the suburban town project which had been planned for the needy, ignored the neediest. Although the two chief administrators of the greenbelts, Rexford G. Tugwell and Will W. Alexander, believed in equal benefits for blacks, prejudice prevailed and blacks were excluded from Greenhills.
