Zavala County, TX flood risk explained
Flood hazard in Zavala County sits at the 67th national percentile, 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 1.6 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
FEMA hasn't published a residential structure count for Zavala County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 1.4% of all residential structures in Zavala County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Zavala County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Zavala County ranks 1085 — 1 being the highest hazard nationally — and 2471 by population among all 3144 counties covered here, where 1 is the largest. About 9,209 people live in Zavala County, Texas, spread over 1,297.407 square miles.
What to do next if you own or are buying in Zavala County

Where Zavala County's figures come from
