How Jefferson County floods

Flash flooding from severe weather events dominates the flood history of Jefferson County, accounting for 61 of the 83 recorded flood events over the last 30 years, alongside 17 standard floods, 3 tropical depressions, and 2 tropical storms. Recent multiday severe weather periods, such as those in March 2023 and April 2025, brought heavy rainfall totals ranging from half a foot to over a foot in many locations, triggering widespread flash flooding and river flooding alongside tornadoes, damaging winds, and large hail.

National Flood Insurance Program claims data indicates that historical payouts and water depths vary significantly by zone. Zone A experienced the vast majority of claims with 476 filings, averaging $30,786 per payout with an average recorded water depth of 8 inches. Properties in Zone X recorded 26 claims with an average payout of $21,765 and a higher average recorded water depth of 20 inches. Smaller claim counts occurred in unknown zones, unshaded Zone X, and shaded Zone X, with average water depths ranging from 1 to 5 inches.

Homeowners and real estate agents with properties located within Zone A and Zone X should pay the most attention to flood risks, given the substantial claim volumes and recorded water depths associated with these areas during heavy rainfall events.

Storms on these days led to a few tornadoes as well as hail as large as 3 inches in diameter.

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.

Flood insurance in Jefferson County

If a building in Jefferson 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.
