Bonita Springs sits between the Imperial River, Estero Bay, and the Gulf, where storm surge and river flooding both threaten low-lying homes. Ground-level doorways, garages, and lanais near the water are the first to flood during storms.

The Hammerhead™ Aluminum Flood Plank System

Hammerhead protecting window

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 Bonita Springs 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 Bonita Springs, Lee County

Hurricane Ian’s 2022 surge reached into coastal Bonita Springs, and Hurricane Irma in 2017 caused significant freshwater flooding along the Imperial River. The area faces risk from both coastal surge and inland river flooding.
Much of Bonita Springs falls within FEMA AE and VE zones along the river, bay, and coast, with X zones inland, with flooding driven by the Imperial River, Estero Bay, and the Gulf shoreline near Bonita Beach. Many Bonita Springs properties in AE and VE zones carry NFIP requirements; documented mitigation can support your flood plan. Confirm with your county or insurance for NFIP specifics.
