Seawall Repair Key Biscayne
Seawall repair in Key Biscayne is permitted mainly through Miami-Dade DERM’s Class I program, since the Village code sets no seawall elevation of its own.
We connect Village owners on Hurricane Harbor, Smuggler’s Cove and the bayfront with licensed marine contractors who work there.
Free inspection, a written scope, no obligation.
The aquatic preserve
On Biscayne Bay, building or replacing a seawall needs Board of Trustees approval, given only with rip-rap (Florida Statute 258.397). Bulkhead lines are not moved seaward.
Village approval
Work on the wall that touches a dock needs the Village Building, Zoning and Planning Department’s written approval as well. Hurricane Harbor and Smuggler’s Cove lots follow their own dock table.

Why it matters
Short form
DERM’s short-form permit covers seawall work at mean high water or up to 18 inches waterward. Further out means a County Commission hearing.
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
