How Fayette County floods

Standard riverine flooding dominates Fayette County, accounting for 30 historical events compared to 19 flash flood events over the last 30 years. NOAA storm data records show that slow-moving frontal systems produce heavy rainfall and widespread water accumulation, such as the low-pressure system that dropped 1.5 to 2.5 inches of rain to cause widespread flooding on February 18, 2022. Another similar low-pressure system and cold front moved through the region on July 14, 2025, producing localized flooding from heavy rainfall.

FEMA National Flood Insurance Program records indicate that flood claims are distributed across multiple zones, with Zone A recording 8 claims averaging a $2,445 payout and an average recorded water depth of 1 inch. Zone X unshaded recorded 5 claims with an average payout of $3,220 and an average water depth of 0 inches, while Zone X recorded 4 claims with an average payout of $3,463 and an average water depth of 24 inches. Zone Unknown recorded 2 claims averaging a $124 payout with 0 inches of water depth, and Zone X shaded logged 1 claim with a $0 payout and 0 inches of water depth.

Homeowners and real estate agents with properties located in Zone A and Zone X should pay the closest attention to these flood risks, given the documented claim history and recorded water depths in those areas.

Flood · Feb 18, 2022. Rain overspread the region through the day ahead of a low pressure system moving through the Ohio Valley. Rainfall amounts of 1.5 to 2.5 inches produced widespread flooding.

Flash Flood · May 14, 2022. Scattered thunderstorms developed during the afternoon and evening in a warm and humid airmass that was in place across the Ohio Valley.

Flood insurance in Fayette County

If a building in Fayette County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
