The Department of Community Development administered the City's comprehensive plan and provided direction and support for the City's physical and economic development through community planning. DCD was established in 1969 and assumed the responsibilities of the City Planning Commission and the Urban Renewal Program. In 1972, the Office of Economic Development was created in the Department to provide information to businesses that were expanding or relocating in Seattle. DCD was the lead agency for implementing various types of grant funded projects, such as Neighborhood Improvement Program, Targeted Neighborhood Assistance Program, and Neighborhood Development Program. DCD was abolished in 1992 and its programs were relocated in the Department of Neighborhoods, Department of Housing and Human Services, Planning Department, and other agencies. DCD records include material from the City Planning Commission, Zoning Commission, Metropolitan Arts Commission, Board of Adjustment, and Urban Renewal Program.

The Urban Renewal Program was authorized by Ordinance in 1957 and the first Federal funds allocated for neighborhood studies were received in 1959. The program was designed to eradicate urban "blighted areas" in the City. It was initially administered by the Executive Department, and then transferred to the Department of Community Development in 1969. Conventional urban renewal funding was designated for four neighborhoods: Yesler-Atlantic, University-Northlake, South Seattle, and Pike Place Market. In addition, Neighborhood Development Program funds targeted Leschi, South Park, and North Greenwood. Despite the early identification of neighborhoods and the adoption of urban renewal plans, most projects did not get underway until the mid to late 1960s.
