Brantley County, GA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Brantley County scores at the 20.2th 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 4 years) and coastal storm surge (about once every 83 years). County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Brantley County
Homes with a federally backed mortgage inside Brantley County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy.

Looking beyond the mandated zone, 0.8% of all residential structures in Brantley County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
