Warren County, KY flood risk explained
Flood hazard in Warren County sits at the 87.3th national percentile, a middling flood hazard by national standards; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.5 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Homes with a federally backed mortgage inside Warren 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, 29.3% of them do — 56 active policies against 191 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.3% of all residential structures in Warren County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Warren County ranks
