Clinton County, MO flood risk explained
Flood hazard in Clinton County sits at the 65.6th national percentile, below the national norm for flood hazard; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Clinton County
17.7% of the homes FEMA requires to carry flood insurance in Clinton County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 12 policies against 68 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.1% of all residential structures in Clinton County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
