Culberson County, TX: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Culberson County scores at the 6.6th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. 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 2 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Culberson County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Culberson 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, 0.5% of all residential structures in Culberson County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Culberson County ranks
Among the 3144 US counties FEMA scores for flood hazard, Culberson County ranks 2949 — 1 being the highest hazard nationally — and 3024 by population among all 3144 counties covered here, where 1 is the largest. Culberson County, Texas is home to about 2,254 people across 3,812.156 square miles of land.
