Fort Myers Beach has the most severe documented surge record of any location on this site. The National Hurricane Center recorded peak inundation of 10 to 15 feet above ground level here when Ian made landfall on September 28, 2022. Any conversation about a wall on Estero Island starts from that number.
What this does not tell you
Nothing on this page establishes what your specific wall needs. Requirements turn on your waterway, your scope of work and the current state of local code — all of which change. Use this to know what questions to ask and what a contractor should be able to cite, then confirm with the authority that administers it.
