Hall County, TX flood risk explained
Flood hazard in Hall County sits at the 3.8th 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 once every 2 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Hall County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Hall County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.1% of all residential structures in Hall County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Hall County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Hall County ranks 3031 — 1 being the highest hazard nationally — and 2968 by population among all 3144 counties covered here, where 1 is the largest. Hall County, Texas covers 883.492 square miles and counts roughly 2,828 residents.
Your street may differ from Hall County's average
