Dallam County, TX: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Dallam County scores at the 14.9th 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 7 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
FEMA hasn't published a residential structure count for Dallam 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, 0.3% of all residential structures in Dallam County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Dallam County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Dallam County ranks 2706 — 1 being the highest hazard nationally — and 2616 by population among all 3144 counties covered here, where 1 is the largest. Dallam County, Texas is home to about 7,526 people across 1,503.353 square miles of land.
What to do next if you own or are buying in Dallam County
