How Ward County floods

Flash flooding and river flooding from rapid spring snowmelt and heavy summer rains dominate the flood profile of Ward County, ND, accounting for 15 flash flood and 10 flood events over the last 30 years. Notable recent events include a multi-day heavy rain event in June 2014 that dropped 4.50 inches of rain locally and led to a Federal Disaster Declaration, as well as a late-season rapid snowmelt beginning in April 2013 that caused prolonged flooding along the Souris (Mouse) River and Des Lacs River, resulting in water entering homes in the Project Road area near Burlington and widespread road damage.

Residents and property owners should pay close attention based on historical National Flood Insurance Program (NFIP) claims data across different zones. Zone X properties recorded 630 claims with an average payout of $117,945 and an average recorded water depth of 21 inches, while Zone A properties saw 408 claims with an average payout of $11,666 and an average water depth of 7 inches. Additionally, Zone X unshaded properties experienced significant severity with an average payout of $113,563 and an average water depth of 48 inches across 7 claims, and Zone D logged 47 claims averaging $36,640 with an average water depth of 8 inches.

Flood insurance in Ward County

If a building in Ward 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.
