Coweta County, GA: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Coweta County scores at the 72.1th percentile for flood hazard, rated "Relatively Low" — below the national norm for flood hazard. 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. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
Homes with a federally backed mortgage inside Coweta County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 28.1% of them do — 41 active policies against 146 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.3% of all residential structures in Coweta County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Coweta County compares nationally
