Ector County, TX flood risk explained
Flood hazard in Ector County sits at the 81.7th national percentile, a middling flood hazard by national standards; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 3.9 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Ector County's flood-insurance compliance gap
Out of 5,938 homes FEMA counts inside Ector County's mapped flood zone, 766 carry the flood policy federal law requires there — 12.9% compliance, short of full coverage. Looking beyond the mandated zone, 1.5% of all residential structures in Ector County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
