Jack County, TX flood risk explained
Flood hazard in Jack County sits at the 10.1th national percentile, among the lowest flood hazard in the country; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Out of 58 homes FEMA counts inside Jack County's mapped flood zone, 2 carry the flood policy federal law requires there — 3.5% compliance, short of full coverage. Looking beyond the mandated zone, 0.2% of all residential structures in Jack County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
