How Jefferson Davis Parish floods

Flash flooding driven by heavy rainfall events dominates the local flood profile, accounting for 29 out of 34 recorded flood events over the last 30 years in Jefferson Davis Parish, Louisiana. This pattern is regularly produced by slow-moving cold fronts, upper-level disturbances, and warm fronts, as seen during heavy storms in March and May 2025.

Federal insurance data shows that flood risks extend beyond high-risk areas. Properties located in Zone A account for the highest volume of claims at 198, with an average payout of $32,331 and an average recorded water depth of 5 inches. Meanwhile, properties designated as Zone X recorded 61 claims with an average payout of $29,189 and an average recorded water depth of 7 inches. Additional claims occurred in Zone UNKNOWN (33 claims, average payout $7,595, average water depth 2 inches), Zone X_SHADED (13 claims, average payout $9,125, average water depth 4 inches), and Zone X_UNSHADED (8 claims, average payout $9,040, average water depth 1 inch).

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 Davis Parish

If a building in Jefferson Davis Parish 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.
