Fort Myers sits along the Caloosahatchee River, where riverfront and low-lying neighborhoods are exposed to both storm surge from the Gulf and rising river water. Ground-level doorways, garages, and lanais are usually the first points where water enters a home.

The Hammerhead™ Aluminum Flood Plank System

Hammerhead is a stop-log flood barrier with permanent U-Channel posts mounted on either side of an opening, and rigid aluminum planks slide in and tighten down to create a watertight wall when a storm is coming. Between storms, the planks store compactly and the low-profile posts stay in place.

Custom-sized to every opening: doorways, garages, lanais, loading bays
6063 T-6 extruded aluminum plus stainless steel hardware: corrosion-resistant, USA-made
Patented SureGasket™ + AlumiSeal™: dual sealing for a tight, watertight seal
Rated to about 6 ft with center-post extensions for wider spans
Deploys in minutes by unskilled labor; planks slot in and clamp down
Built for high wind and debris: fixed posts and clamped planks handle the stresses coastal storms bring

For protection above plank height, on larger openings, or around an entire perimeter, Flood Barrier Systems offers a full line of complementary products.

PREPARE IN ADVANCE

Get Fort Myers storm-ready before hurricane season

The best time to plan flood protection is before a storm is named. Hammerhead posts install once and stay in place, so when a warning is issued your planks slot in and tighten down in minutes, no scramble for sandbags, no last-minute contractors.

Assess early: book a free property assessment.
Install posts now: the permanent posts go in on a calm day, not the day before landfall.
Store planks on-site: compact storage keeps everything ready to deploy.
Deploy fast: slot, tighten, and clamp when a storm approaches.

Waiting until a storm is in the forecast often means limited availability. Preparing in advance means you are protected the moment you need it.

LOCAL FLOOD CONTEXT

Flood risk in Fort Myers, Lee County

Hurricane Ian in 2022 brought catastrophic surge to the Fort Myers area, flooding riverfront districts and coastal neighborhoods, and later storms including Helene renewed the threat to ground-level openings. Homeowners across the area have since prioritized barriers that can be deployed quickly ahead of a storm.

Much of Fort Myers falls within FEMA AE and VE zones along the river and coast, with flooding driven by the Caloosahatchee River, tidal creeks, and low-lying riverfront districts. Riverfront and coastal Fort Myers properties in AE and VE zones commonly carry NFIP requirements; ask about how a documented barrier system fits your flood plan. Confirm with your county or insurance for NFIP specifics.

LOCAL PROOF

Hammerhead projects near Fort Myers

A Fort Myers homeowner in a FEMA flood zone, after damage from Hurricane Ian, worked with Garrison to install the Hammerhead Aluminum Flood Log System, with four separate custom barriers protecting the lanai, the double and single garage doors, and entry doors. The systems have since helped protect the home through additional storms, including Hurricane Helene.
