Northern Missouri
River-bottom land in Carroll County sits in mapped floodplain
Much of southern Carroll County is Missouri River bottomland, and parcels there can fall in FEMA-mapped special flood hazard areas that affect insurance and lending.
Carroll County’s southern edge runs along the Missouri River. The land there is river-bottom farmland: low, flat ground near the water. This is the kind of ground that FEMA maps as a special flood hazard area. FEMA is the federal agency that runs the National Flood Insurance Program. A special flood hazard area is land FEMA marks as high-risk for flooding.
If you buy property in the bottoms, the flood-zone label matters. A lender on a federally backed mortgage will usually require flood insurance for a building in a high-risk zone. The zone also affects how much you pay.
Before you buy or build, look up the address on FEMA’s Flood Map Service Center to see its zone. Also ask whether a levee or drainage district serves the area. Levee status can change how a parcel is mapped and protected.
Do not treat the lack of a recent flood as proof a parcel is safe. The Missouri bottoms have flooded again and again within living memory.
