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.

Citywide context cannot establish a parcel's flood zone, historic designation, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
