Seawall Construction & Replacement for Miami Beach waterfront properties
When a Miami Beach 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 Miami Beach sites that land equipment cannot. More about seawall construction.
Seawall Construction in Miami Beach: what's specific here
What a new Miami Beach wall has to meet: City Code Sec. 54-62 (Ord. 2021-4393, amended by Ord. 2025-4754 on 2025-07-16): all new seawalls and seawalls undergoing substantial improvement must reach 5.7 ft NAVD88; less-than-substantial repairs may stay at 4.0 ft NAVD88 only if designed for a future 5.7 ft. The city's FAQ defines a substantial repair as $300 or more per linear foot. [mbrisingabove.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: City of Miami Beach Building Department + Miami-Dade DERM Coastal Resources Section (Class I) + FDEP / USACE as applicable. The city FAQ lists the building-permit package (site plan, structural design, elevation certification) and states DERM Coastal Resources approval is required for seawall construction, with FDEP for state-owned bottom and a USACE Section 404 permit for any dredge or fill.
