Seawall damage after a storm.
Record it, then repair it right.

By Jacksonville SeawallUpdated: 2026-10-24

Irma, Matthew, Ian, Nicole and the October 2025 nor’easter all left damaged walls along the St. Johns and the coast. Here is the order of steps that protects your safety, your claim and your permit options.

First, keep people off unstable ground

Stay off sunken or cracked areas behind the wall, keep vehicles, boats on trailers and heavy items away from the edge, and do not stand on a leaning cap. Report fuel or oil sheens to the State Watch Office at 800-320-0519 or the National Response Center at 800-424-8802.

Discharge Notification

Photograph before anything is moved

  • Take wide shots of the whole wall and close-ups of each crack, gap, lean and sinkhole, with something for scale.
  • Photograph the water line or debris line left on fences, docks and buildings.
  • Note the date and the peak water level reported at your nearest NOAA gauge.
  • Keep small samples and receipts if you must do emergency work before an adjuster visits.

File the right claims

Flood policies exclude the seawall itself, but water that reached the house may be a flood claim and wind damage a homeowners claim. If you have both kinds of damage and both policies, Florida DFS advises filing with each insurer. NFIP policyholders must send the signed Proof of Loss within 60 days.

Details are in the seawall insurance guide.

Emergency repair rules work in your favor, with limits

Florida exempts restoring a seawall at its previous location, or within 18 inches waterward of it, from state environmental resource permitting. The rule version limits this to walls damaged within the past year by a discrete event such as a storm, or with only minimal disturbance. The federal Nationwide Permit for maintenance covers storm-damaged structures if work starts or is under contract within two years of the damage.

These exemptions do not replace your building permit, and oceanfront property has its own coastal armoring rules. See the permit guide and the oceanfront armoring guide.

Why one storm can set up the next failure

Hurricane Irma set the modern high-water record at the Main Street Bridge in 2017. In 2022, Ian was followed six weeks later by Nicole, which set the record at Mayport. The National Hurricane Center notes Ian likely left the coast more vulnerable. Walls that lost backfill or anchors in one event may look fine until the next high water.

Have a damaged wall assessed even if it is still standing. See the Jacksonville water levels guide for gauges and flood stages.

Avoid post-storm contracting traps

Verify the state license and insurance before any deposit, never sign an assignment of benefits, and remember only a licensed public adjuster may adjust your claim for a fee. The contractor checklist walks through each step.
