Bibb County, GA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Bibb County scores at the 80.4th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Bibb County's flood-insurance compliance gap
Out of 203 homes FEMA counts inside Bibb County's mapped flood zone, 97 carry the flood policy federal law requires there — 47.8% compliance, short of full coverage. Looking beyond the mandated zone, 0.4% of all residential structures in Bibb County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Bibb County against the rest of the country
