How Howard County floods

Flash flooding and standard flooding from severe thunderstorms equally dominate the flood profile of Howard County, Nebraska, with each hazard accounting for 11 recorded events over the last 30 years according to the NOAA Storm Events Database. Recent historical impacts include multiple rounds of significant heavy rainfall from thunderstorms in May 2024, as well as a persistent narrow band of heavy rain that tracked through the region over a 10-hour period between June 21 and June 22, 2024.

National Flood Insurance Program records indicate that flood claims have been filed across multiple zones, though the highest concentration of claims occurs in high-risk areas. Specifically, Zone A accounts for 13 claims with an average payout of $21,516 and an average recorded water depth of 4 inches. Properties in Zone X recorded 2 claims averaging $27,672 with an average water depth of 1 inch. Zone UNKNOWN and Zone X_UNSHADED each recorded 2 claims with average payouts of $1,008 and $0, respectively, and an average recorded water depth of 0 inches.

Homeowners, real estate agents, and journalists should pay the most attention to properties located within Zone A, as this zone experiences the highest frequency of claims and measurable water depths, alongside properties situated in areas susceptible to rapid summer convective rainfall and flash flooding.

  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Howard County

If a building in Howard 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.
