Cape Coral’s canal network gives it more miles of waterway than almost any city in the country, and that same water becomes a liability when storms arrive. Homes and businesses along the canals face storm surge, tidal backflow, and heavy-rain flooding that reaches ground-level doorways and garages first.

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 Cape Coral 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 Cape Coral, Lee County

When Hurricane Ian struck Lee County in 2022, storm surge and canal overflow pushed water into homes across Cape Coral, causing widespread damage to ground-floor living spaces and garages. The event underscored how quickly canal-front properties can flood even inland of the immediate coast.

Much of Cape Coral falls within FEMA AE and VE zones along the canals and coast, with flooding driven by the 400-plus miles of canals, the Caloosahatchee River, and Matlacha Pass. Many Cape Coral properties in AE and VE zones carry National Flood Insurance Program requirements, and documented flood mitigation can be part of the conversation about elevation certificates and coverage. Confirm with your county or insurance for NFIP specifics.
