Seawall Construction & Replacement for Longboat Key waterfront properties
When a Longboat Key seawall is past repairing, the job becomes a replacement: the old wall comes out and a new one goes in. We design, build, remove and repair seawalls and coastal structures, and we work closely with licensed engineers to evaluate the site and settle on the design.
Walls are built in engineered sheetpile, concrete and timber, and the shoreline work extends to riprap revetments, jetties and breakwaters. The design follows the site: soil conditions, water depth and the layout of the property. Materials run to concrete, vinyl, steel and composite systems.
We manage the project end to end, from site assessment and engineered design through permitting support, construction and the post-construction inspection. Our marine-capable equipment includes crane barges and work barges, which let us reach Longboat Key sites that land equipment cannot. More about seawall construction.
Seawall Construction in Longboat Key: what's specific here
What a new Longboat Key wall has to meet: Town Commission voted 7-0 on April 1, 2024 to raise the maximum allowable seawall height from 4.5 ft to 6 ft (Chapter 151), citing 6 inches of sea-level rise in 20 years and walls being overtopped; by March 2025 the town had issued 27 permits to raise seawall heights. [yourobserver.com] A repair can keep an existing wall as it stands; a replacement is new construction, so it is built to the current standard.
Permits: Town of Longboat Key (Ch. 151; max 6 ft) + FDEP + USACE. Town review raised the cap to 6 ft in 2024; FDEP 62-330.051(12)(b) exempts restoring a wall damaged within the last year up to 18 in waterward; Corps SPGP VI covers shoreline stabilization via DEP self-certification.
