The Flooding Character of Crawford County

Flash flooding and river overflow have been the primary flood events in Crawford County over the last 30 years, with 20 flash flood events and 14 flood events recorded. For example, heavy rainfall in mid-December 2015 caused river flooding and closed county roads due to high water. Earlier, in March 2019, a deep snowpack combined with frozen soils contributed to widespread flooding across the region.

National Flood Insurance Program (NFIP) claims data indicates that properties in Zone A have experienced the deepest water, averaging 7.0 feet, with an average payout of $17,335. Zone X_UNSHADED saw the highest average payouts at $32,465, despite an average water depth of 1.2 feet. Properties in Zone X also incurred significant losses, with an average payout of $14,328 and an average water depth of 3.2 feet.

Homeowners, journalists, and real estate agents should pay particular attention to properties located in Zone A and near rivers and streams, as these areas have historically experienced deeper flooding and higher claim payouts. Residents in Zone X_UNSHADED and Zone X should also be aware of the potential for significant financial losses due to flooding.
