The idea for this project grew out of an investigation completed in 1990 for the Urban Redevelopment Authority of Pittsburgh, PA. The survey attempted to assemble the fullest, most accurate info. possible through combined archival research, oral history, & field investigation. Using the records of the Allegheny County Historic Resource Survey to establish an initial data base of communities & sites to be researched, the project team went on to expand the list of sites to include over 6 districts & 290 individual sites, incl. both extant & non-extant sites.
