When Macomb Township was built

Macomb Township's housing is concentrated in a single era, peaking in the two-thousands at about 33% of today's homes; relatively few of the stock, 4%, predates 1960. These are mid-range homes for the metro, and 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 clay drain tiles.

How basement risk varies inside Macomb Township

What this means for Macomb Township homeowners

Macomb Township scores toward the lower end of the metro range, largely because of its newer housing. Risk is still real on clay soil, so watch for symptoms after heavy rain. Among its immediate neighbors, Macomb Township scores lower than Shelby Township, so the block next door is a better guide than any metro-wide average.

Why Macomb Township homes face basement risk

Basement risk in Macomb Township comes down to two things: how old its houses are and the clay beneath them. With relatively few of its homes, 4%, built before 1960 and the biggest share going up in the two-thousands, many sit on original clay drain tile, and southeast Michigan's dense clay holds water against those foundations rather than letting it drain. If a backup has already put water on a floor here, Michigan law leaves a narrow window to file a written claim: how to file a sewer-backup claim in metro Detroit →.

FEMA disaster assistance after June 2021

That count is a floor, not a ceiling: it only includes households who applied to FEMA, not every home that took on water.

What to do about it

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