Shaded areas are FEMA’s mapped flood hazard zones in and around Iberville Parish, Louisiana. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
Flash flooding from slow-moving thunderstorms, tropical systems, and hurricanes dominates the flood history of Iberville Parish, supported by 10 flash flood events, 6 tropical storms, 6 general floods, and 5 hurricanes over the last 30 years. Recent events underscore these risks, including the April 2025 flash flood caused by a stalled mesoscale convective vortex that brought slow-moving and training storms over Addis, Brusly, and Plaquemine, rendering streets impassable and water entering some buildings. Additionally, Hurricane Francine brought torrential rainfall and flash flooding in September 2024.
NFIP claim data indicates that property owners across multiple zones face distinct risks. Zone A accounts for the highest claim volume with 347 claims averaging $21,277 and an average recorded water depth of 4 inches. Meanwhile, properties in Zone X recorded 134 claims with a higher average payout of $52,378 and an average water depth of 8 inches, and Zone V recorded 19 claims with an average water depth of 14 inches. Homeowners and real estate agents in both high-risk Special Flood Hazard Areas and moderate-to-low risk zones should pay close attention to these historical claim patterns and average water depths when assessing property vulnerability.
Summary written from NOAA storm reports and NFIP claims for this county. Not a prediction.
20% of Iberville Parish’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

In flood insurance claims here that reported a flood depth, the average was 5 inches.

Flash Flood · Apr 24, 2025. On the morning of April 24th, a remnant mesoscale convective vortex (MCV) that originated off the southeast Texas coast drifted along the northern Gulf and eventually stalled near the Baton Rouge metro area. The first storms developed on the west side of the Mississippi River over Addis, Brusly, and Plaquemine, where slow-moving and training cells led to significant flash flooding, rendering many streets impassabl…
Tropical Storm · Sep 11, 2024. Hurricane Francine formed as a tropical storm in the Gulf of Mexico on September 9, 2024, and intensified into a Category 2 hurricane before making landfall near Houma, Louisiana, on the morning of September 11. With sustained winds of 100 mph and gusts peaking at 105 mph, Francine brought widespread damage to southeastern Louisiana and southern Mississippi. A storm surge of 6-9 feet inundated low-lying coastal ar…
Hurricane (Typhoon) · Aug 29, 2021. The ninth named storm, fourth hurricane, and second major hurricane of the 2021 Atlantic hurricane season, Ida originated from a tropical wave in the Caribbean Sea on August 23rd. On August 26th, the wave developed into a tropical depression, which organized further and became Tropical Storm Ida later that day, near Grand Cayman. On a northwestward track, Ida intensified into a hurricane on August 27, just before…
Flash Flood · May 17, 2021. In the overnight hours on May 17th into the early morning on May 18th, a cluster of slow moving severe thunderstorms associated with a weak mid-level disturbance drifted east across southeastern Louisiana. Ample overnight instability and weak steering flow resulted in damaging wind gusts, flash flooding and a few isolated weak tornadoes.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Iberville 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.
