When Brownstown Township was built
The housing stock in Brownstown Township peaked in the 2000s, when about 23% of today's homes were built. In total, 10% of Brownstown Township 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 Brownstown Township homes face basement risk
Basement flooding in Brownstown Township 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. Brownstown Township sits on Lake Erie, and low-lying ground near the water keeps the seasonal water table close to basement floors, so hydrostatic seepage can matter as much as sewer capacity here.

Often not. Standard Michigan homeowners policies commonly exclude sewer backup and groundwater unless you carry a specific endorsement. Before the next storm, it is worth reading our guide on whether insurance covers basement flooding in Michigan and checking your declarations page.
