Southampton County, VA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Southampton County scores at the 29.8th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is split between inland river flooding (about once every 1 years) and coastal storm surge (about once every 83 years). That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Southampton County's flood-insurance compliance gap
28.2% of the homes FEMA requires to carry flood insurance in Southampton County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 96 policies against 341 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 1.7% of all residential structures in Southampton County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Southampton County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Southampton County ranks 2263 — 1 being the highest hazard nationally — and 1937 by population among all 3144 counties covered here, where 1 is the largest.
