St. Louis Region
Riverfront and River Des Peres areas carry floodplain homework
Parts of the City near the Mississippi and the River Des Peres sit in mapped flood zones, which affects insurance and what questions to ask before buying.
St. Louis City fronts the Mississippi River and is drained in part by the River Des Peres, and some low-lying areas fall within FEMA-mapped flood zones. A flood-zone designation is the first question, not the last: it can affect flood-insurance expectations and lender requirements, and the official FEMA Flood Map Service Center is where to check a specific address. For an older industrial riverfront city, the practical step is to look up the parcel’s flood-zone status early rather than assuming an inland address is automatically clear.
