In Berman v. Parker (1954) 348 U.S. 26, the United States Supreme Court deferred to the legislative and agency determination that the blighted Washington D.C. area of about 5,000 residences, which included unrepairable housing for 64.3 percent, should be condemned and redeveloped in part for streets, schools and other public facilities and the remainder to be redeveloped by private parties for low-cost housing, among other purposes. (Id. at pp. 30-31.) The Court declined to address in isolation the challenge of a department store owner that his store was not itself blighted, explaining "community redevelopment programs need not, by force of the Constitution, be on a piecemeal basis--lot by lot, building by building." (Id. at p. 35.)
