When Southgate was built
The housing stock in Southgate peaked in the 1950s, when about 34% of today's homes were built. In total, 49% of Southgate homes predate 1960. That matters because basements built before the 1960s typically lack the sump pumps, perimeter drain tile, and backwater valves that became standard later, leaving many on their original, aging clay drain tiles.

Why Southgate homes face basement risk
Basement flooding in Southgate is mostly a function of housing age and soil. Older homes were built with clay drain tiles that crack and clog over decades, and the dense clay across southeast Michigan holds water against foundations rather than letting it drain.
