How much flood risk does Snyder County actually carry?
Snyder County lands at the 71.2th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — 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 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Snyder County's flood-insurance compliance gap
21.1% of the homes FEMA requires to carry flood insurance in Snyder County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 181 policies against 857 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Snyder County, not just the ones FEMA mandates, 1.4% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
