What matters for project planning
The City of Dearborn publishes its own home-improvement and construction permit guidance, and since 2021 has invested more than $25 million in Rouge River flood-preparedness and stormwater work — including clearing more than 50 logjams along a 2.5-mile stretch of the river that lowered water levels by over a foot and increased storm-flow capacity by roughly 70%.

Verify the property, not just the city
None of this citywide research tells you one parcel’s flood zone, historic status, permit rules, soil type, or what’s actually behind the walls. Confirm those with the right authority and your chosen provider before work starts.
