Seawall Inspection Marathon
Seawall inspection in Marathon matters on canal lots that took Irma’s surge in 2017, when the city recorded a high-water mark 3.72 feet above ground (National Hurricane Center).
We put Marathon owners in touch with licensed marine contractors who inspect canal and harbor walls.
Free inspection, findings in writing, no obligation.
What happens next
Any repair is designed by a professional engineer (Marathon LDR Sec. 104.64). A replacement keeps the footprint, and the City Biologist reviews whether riprap would work instead of a wall.

Why it matters
What a report covers
Cap cracks, joint gaps, tie-backs, toe scour and soil loss behind the wall. The NOS Vaca Key gauge peaked at 2.6 feet above mean higher high water during Irma, and canal walls near Boot Key Harbor saw the same water.
What a free inspection includes
A contractor comes to your property, looks at the structure above and below the waterline where needed, and tells you what is actually happening.
You get a written scope and estimate. No obligation, no trip fee.
- On-site assessment of the structure and surrounding soil
- Photos and a plain-English explanation of the problem
- Written estimate with scope and materials
- Repair versus replacement guidance where both are options
