Is Anderson County, TX in a flood zone?
FEMA's National Risk Index puts Anderson County's flood hazard at the 69.7th percentile nationally — below the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.2 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.
Anderson County's flood-insurance compliance gap
10.4% of the homes FEMA requires to carry flood insurance in Anderson County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 17 policies against 164 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Anderson County, not just the ones FEMA mandates, 0.3% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
