Dent County, MO Flood Zone & Flood Risk Data
Dent County, MO: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Dent County scores at the 32.7th percentile for flood hazard, rated "Very Low", among the lowest flood hazard in the country. The hazard here is driven by inland rivers and flash flooding rather than the coast, FEMA's model puts a flood event here at about 2.5 times a year. That's a county-wide figure, not a per-address one, FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
Homes with a federally backed mortgage inside Dent County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 6.9% of them do, 6 active policies against 87 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.1% of all residential structures in Dent County carry flood coverage voluntarily or otherwise, relevant because most NFIP claims nationally come from outside the mapped SFHA.
