Henry County, AL: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Henry County scores at the 38.4th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. 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 once every 3 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Henry County's flood-insurance compliance gap
10.3% of the homes FEMA requires to carry flood insurance in Henry County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 18 policies against 174 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.3% of all residential structures in Henry County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Henry County against the rest of the country
