How Doniphan County floods

Flash flooding and river flooding from heavy rainfall and snowmelt shape the flood risk profile in Doniphan County, Kansas, backed by 13 flash flood events and 8 general flood events recorded over the last 30 years in the NOAA Storm Events Database.

Significant historical impacts include the March 2019 event, when heavy rain and melting Northern Plains snowpacks triggered major flooding along the Missouri River, worsened by levee failures. Continuous heavy precipitation sustained this major river flooding through April, May, and June of 2019, keeping parts of the floodplain inundated for weeks.

Property owners in low-risk or unshaded zones should pay close attention to historical insurance data. Federal records show 57 claims in Zone X_UNSHADED with an average payout of $13,995 and an average recorded water depth of 6 inches, alongside 38 claims in Zone X averaging a $5,211 payout and an average recorded water depth of 1 inch.

Numerous locations along the Missouri River receiv…

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.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  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 Doniphan County

If a building in Doniphan 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.
