What the risk data says about Dearborn
Dearborn carries a Basement Risk Index of 76 out of 100, ranking #18 of 116 metro Detroit communities, high risk on our public-data index. It runs where it does mostly on housing age: 71% of Dearborn homes were built before 1960, before sump pumps, perimeter drain tile, and backwater valves were standard, on the region's heavy clay soil. That is the context for the license and diagnosis questions here; the full driver table, the map, and how Dearborn compares to its neighbors are on the Dearborn basement-risk breakdown →
Part of Dearborn runs on combined sewers or drains to a combined-overflow district. If your block sits in the combined section, sewer backup, not wall seepage, is the failure mode to price first. Check how we classified Dearborn's sewers →

Frequently asked questions
Why do basements flood in Dearborn?
Mostly housing age and soil. 71% of Dearborn homes were built before 1960, before sump pumps, exterior weeping tile, and backwater valves were standard, and the heavy clay soil across southeast Michigan holds water against those older foundations rather than draining.
Is a Basement Risk Index of 76 high for Dearborn?
A score of 76 is above the metro Detroit median of 37 (U.S. Census ACS 2020-2024, updated July 2026), ranking #18 of 116 communities. It is worth a prevention check before the next heavy rain.
Does Dearborn have combined sewers?
Yes, in part, per the operator and county records checked July 2026, so sewer backup, not just wall seepage, is a real failure mode here. See our metro combined-sewer map.
