When Riverview was built
The housing stock in Riverview peaked in the 1960s, when about 24% of today's homes were built. In total, 32% of Riverview 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.

Riverview scores in the moderate band, but moderate is not zero on clay soil. Prevention is cheap relative to a flooded basement, and a free check tells you what you are working with.
Why Riverview homes face basement risk
Basement flooding in Riverview 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.
How Riverview compares
Riverview's Index of 32 is below the metro Detroit median of 32. It ranks #59 of 117 communities region-wide.
Does insurance cover it?

What to do about it
- Lower risk is not zero risk on the region's clay soil, a free prevention check takes about 30 minutes.
- Watch for symptoms after storms; what you see at your own home matters more than any average.
- Maintain gutters and grading, the two cheapest protections any Michigan home has.
