How much flood risk does Troup County actually carry?
Troup County lands at the 67.7th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 3 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Troup County's flood-insurance compliance gap
11.9% of the homes FEMA requires to carry flood insurance in Troup County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 37 policies against 311 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Troup County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
