How Rush County floods

Flash flooding from slow-moving summer thunderstorms and heavy rainfall dominates the flood risk in Rush County, Kansas. Over the last 30 years, the NOAA Storm Events Database recorded 18 flash flood events and 8 general flood events. For example, on May 16, 2021, a passing shortwave dropped heavy rainfall over saturated ground, causing flooding along the Highway 96 corridor. Similarly, on May 23, 2019, a stationary front fueled thunderstorms that triggered flash flooding during the late afternoon and evening.

Federal flood insurance records from FEMA show that claims are concentrated in Zone A. Within this zone, historical claims averaged 7 total filings with an average payout of $5,349 and an average recorded water depth of 1 inch.

Homeowners, real estate agents, and journalists should pay the most attention to properties situated in Zone A, areas near the Highway 96 corridor, and locations prone to runoff over saturated soils where slow-moving storms frequently stall.

Flood insurance in Rush County

If a building in Rush 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.
