Grant County, AR flood risk explained
Flood hazard in Grant County sits at the 16.7th national percentile, among the lowest flood hazard in the country; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.2 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Grant County
16.1% of the homes FEMA requires to carry flood insurance in Grant County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 13 policies against 81 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.4% of all residential structures in Grant County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
