How Pickaway County floods

Standard river flooding and flash flooding from heavy rainfall dominate the flood history of Pickaway County, OH, with NOAA records detailing 65 general flood events and 28 flash flood events over the last 30 years. A specific example of this occurred in July 2025, when a stalled cold front in the Ohio Valley produced heavy rainfall, runoff, and flooding from showers and thunderstorms.

Federal insurance data shows that flood risks extend across multiple zones. Properties in Zone X recorded 34 National Flood Insurance Program claims with an average payout of $8,649 and an average water depth of 12 inches. Meanwhile, properties in Zone A logged 33 claims with an average payout of $13,714 and an average water depth of 7 inches. A small number of claims also occurred in unknown zones and unshaded Zone X properties.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located in both designated high-risk flood areas like Zone A and moderate-to-low risk areas like Zone X, as both zones have accumulated significant historical claim activity and water depths.

The zones you’ll see on the map

Flood insurance in Pickaway County

If a building in Pickaway 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.
