What matters for project planning
Sterling Heights requires a floodplain development permit for any development within the 100-year floodplain -- not just new construction, but filling, excavation, and other site work -- reviewed by the city's Office of Engineering. Depending on the effect on the floodplain, a permit from the Michigan Department of Environment, Great Lakes, and Energy or FEMA may also apply. The city adopted its own Stormwater Management Standards, effective May 17, 2023, and prohibits illicit discharges into the city storm sewer.
Official sources
Verify the property, not just the city
General city-level information can't pin down one parcel's flood zone, historic status, permit requirements, soil conditions, or hidden construction. Parcel-level flood zone, historic-district status, and permit requirements should be confirmed with Macomb County's authority before work begins.
