How Kittson County floods

Riverine flooding driven by long-duration spring snowmelt dominates Kittson County, supplemented by recurring flash floods. Over the last 30 years, NOAA recorded 37 flood events alongside 16 flash flood events. Recent activity includes significant spring snowmelt flooding that began in late April 2023 and persisted into early May 2023.

National Flood Insurance Program records show claims concentrated across multiple zones. Properties categorized under Zone UNKNOWN account for 114 claims with an average payout of $4,436 and an average recorded water depth of 3 inches. Zone A accounts for 112 claims with an average payout of $11,819 and an average recorded water depth of 30 inches. Zone X_UNSHADED has 14 claims averaging $1,962 with an average depth of 3 inches, while Zone X records 6 claims averaging $10,047 with an average depth of 0 inches, and Zone X_SHADED contains 1 claim averaging $9,282 with an average depth of 0 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located in Zone A, which experiences the highest average water depths and substantial payouts, as well as properties situated in areas with unmapped or unknown flood zones where historical claims are heavily clustered.

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 Kittson County

If a building in Kittson 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.
