How Hayes County floods

Flash flooding from intense precipitation dominates the flood profile of Hayes County. According to NOAA Storm Events Database records from the past 30 years, the county experienced 25 flash flood events alongside 3 general flood events.

Heavy rainfall events frequently threaten local infrastructure. For example, during the early morning hours of May 26, 2023, very heavy rain fell across southern portions of Hayes and Chase counties, causing flash flooding that resulted in the closure of Highway 25 and Highway 6 in southern Hayes County due to water covering the roadway.

Property owners and real estate professionals in low-lying areas, near regional highways, and along local drainage paths should pay the closest attention to flood risks during periods of heavy seasonal rainfall.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Hayes County

If a building in Hayes 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.
