Flint context
Flint's housing stock reflects the city's own industrial waves: modest worker housing built near the Durant-Dort carriage works and, after 1908, the General Motors plants -- including the planned streets of the Civic Park Historic District -- followed by ranch-house subdivisions that spread into Genesee County's townships as the auto industry grew through the 1950s and 60s. Much of that ground sits on the same slow-draining clay that underlies Genesee County generally, and many of those postwar homes still carry the clay-tile or early corrugated footing drains that were standard into the 1980s -- systems now old enough to crush, clog, or collapse and leave hydrostatic pressure with no relief.
