The Urban Renewal-era Resources in the United States Multiple Property Documentation (MPD) form explores the historic contexts and impacts of the mid- to late-20th century urban renewal program and establishes the significance of the program as it impacted communities across the nation. The MPD is intended to facilitate the nomination of urban renewal areas. Between 1949 and 1974, the federal government partnered with local municipalities to stimulate substantial changes to the physical character of urban environments through urban renewal projects. Project sizes ranged from less than one acre to hundreds of acres, and usually consisted of land acquisition, clearance, rehabilitation, and pre-development activities such as building new roads and installing new infrastructure. Once the land had been prepared, local municipalities would sell to private interests, who then undertook the actual developments on the project land. The effects of these changes to countless communities continue to be felt and observed and the products of urban renewal constitute a significant chapter in American history.
