How Vernon Parish floods

Flash flooding driven by severe storms dominates the local flood history, backed by 27 flash flood events and 8 general flood events recorded over the last 30 years alongside tropical storms and hurricanes. Recent occurrences include heavy rainfall and thunderstorms from a slow-moving frontal system in April 2024, and multiple rounds of heavy rain, severe weather, and flooding in late December 2024.

National Flood Insurance Program records show that flood risks extend beyond high-risk areas. Properties in Zone A account for the highest claim volume with 220 claims averaging a 12-inch recorded water depth and a $34,516 average payout. Meanwhile, Zone X properties have recorded 91 claims with an average water depth of 14 inches and a $35,743 average payout.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within both Zone A and Zone X, as both zones experience significant claim frequencies and substantial average water depths during flood events.

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 Vernon Parish

If a building in Vernon 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.
