Hays County, TX flood risk explained

Flood hazard in Hays County sits at the 93.2th 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 3.8 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.

Who actually carries the flood insurance FEMA requires

Out of 2,033 homes FEMA counts inside Hays County's mapped flood zone, 894 carry the flood policy federal law requires there — 44% compliance, short of full coverage. Looking beyond the mandated zone, 2.3% of all residential structures in Hays County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
