How much flood risk does Nacogdoches County actually carry?
Nacogdoches County lands at the 75.6th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.6 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.
Nacogdoches County's flood-insurance compliance gap
19% of the homes FEMA requires to carry flood insurance in Nacogdoches County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 57 policies against 300 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Nacogdoches County, not just the ones FEMA mandates, 0.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
