Gilchrist County, FL: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Gilchrist County scores at the 31.4th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is split between inland river flooding (about once every 7 years) and coastal storm surge (about once every 100 years). That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Mandatory flood insurance compliance in Gilchrist County
Out of 808 homes FEMA counts inside Gilchrist County's mapped flood zone, 142 carry the flood policy federal law requires there — 17.6% compliance, short of full coverage. Looking beyond the mandated zone, 2.3% of all residential structures in Gilchrist County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
