Claiborne County, TN: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Claiborne County scores at the 51.7th 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 1 years. 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
7.9% of the homes FEMA requires to carry flood insurance in Claiborne County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 18 policies against 229 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 Claiborne County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Claiborne County compares nationally
