Michigan flood zone map and environmental check
Michigan regulates contaminated land under its own law: Part 201 for contamination and Part 213 for leaking tanks. The state puts both on a public map, so a buyer can see listed sites near a building before calling anyone.

Official flood maps for Michigan
FEMA’s Flood Map Service Center has the effective flood map for every Michigan address. The state also runs:
Michigan Department of Environment, Great Lakes, and Energy (EGLE)
The state's NFIP coordinator: flood maps, floodplain permits and local contacts.
Map tools usually show the zone at the address pin. On a commercial lot, the buildings can sit in a different zone than the pin. Our free check shows which buildings are in the 1% and 0.2% annual-chance flood areas.
Contamination and tank records in Michigan

Map of Part 201 contamination sites and Part 213 leaking tank sites. It replaced the old Environmental Mapper.
A listed site next door matters as much as one on your lot: leaks travel with groundwater. Look at what’s around the property, not only the address.
