Is Guadalupe County, TX in a flood zone?
FEMA's National Risk Index puts Guadalupe County's flood hazard at the 95.6th percentile nationally — well above 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 2.9 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Guadalupe County's flood-insurance compliance gap
Out of 4,390 homes FEMA counts inside Guadalupe County's mapped flood zone, 1,749 carry the flood policy federal law requires there — 39.8% compliance, short of full coverage. Across all residential structures in Guadalupe County, not just the ones FEMA mandates, 3.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
