What Matters for Project Planning
Grand Rapids participates in the National Flood Insurance Program, and land near the Grand River and its tributaries can fall within FEMA-designated Special Flood Hazard Areas, where projects may require an Elevation Certificate and compliance with the city's floodplain development standards under Chapter 32 of its code of ordinances. The city promotes Low Impact Development as its preferred stormwater strategy, and a 2021 state MS4 permit added a requirement that most development and redevelopment projects retain the runoff difference for the 2-year, 24-hour storm.

Verify the Property, Not Just the City
Citywide context cannot establish a parcel’s flood zone, historic designation, permit requirements, soil conditions, or concealed construction. Check those details directly with the local authority and the provider you choose before work gets underway.
