Georgetown County, SC flood risk explained
Flood hazard in Georgetown County sits at the 86.4th national percentile, well above the national norm for flood hazard; driven by coastal storm surge rather than inland rivers — FEMA's model puts a surge event here at about 3.4 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 Georgetown 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, 20.7% of all residential structures in Georgetown County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Georgetown County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Georgetown County ranks 451 — 1 being the highest hazard nationally — and 828 by population among all 3144 counties covered here, where 1 is the largest.

Your street may differ from Georgetown County's average
