One of the few maps (maybe the only map) of vacant land in the 1970s in Detroit came from the Housing and Urban Development’s (HUD) assessment of their inability to maintain their growing inventory of properties and land. This map was produced by the Detroit News for a series of stories on HUD’s Detroit inventory.

This map shows there were 4,763 vacant lots owned by HUD which gives a rough sense of where there may have been more Farm-a-Lot programming.
