Sea Walls in Coral Gables, FL
Guardians of the Coastline: Protecting Property and Preserving Beauty — serving Coral Gables and the surrounding waterfront communities.
Who permits seawall work in Coral Gables?
Seawall work in Coral Gables goes through the City of Coral Gables Development Services Department, but because the wall sits at or below the waterline, it also needs preliminary approval from Miami-Dade DERM, and often U.S. Army Corps of Engineers review since the Coral Gables Waterway and its canals are navigable water. The city's Public Works Department monitors the Waterway as an indicator of sea-level rise and aquatic health, which factors into how shoreline projects are reviewed.
Do Coral Gables seawalls need to meet hurricane wind standards?
Seawalls themselves are engineered primarily for water and soil loads rather than wind, but any cap, railing, or attached structure on a Coral Gables seawall falls under the Florida Building Code's High-Velocity Hurricane Zone requirements that apply to Miami-Dade County. That's an added design layer beyond what many non-HVHZ Florida coastal cities require.
What sea walls looks like in Coral Gables
Coral Gables sits inside Miami-Dade County's High-Velocity Hurricane Zone, where the Florida Building Code requires standard (Risk Category II) structures to be engineered for wind loads up to 175 mph. The city's Public Works Department also actively monitors the Coral Gables Waterway as an indicator of sea-level rise and aquatic health.
The Coral Gables Waterway is an approximately 8-mile canal system dug in the 1920s under developer George Merrick's "American Venice" plan, running from Biscayne Bay west to Cartagena Plaza before curving north alongside Riviera Drive toward the Biltmore Golf Course.

We regularly work in Gables Estates, Cocoplum and Old Cutler Bay, and coordinate permitting with the City of Coral Gables Development Services Department (Building Division and Public Works Department), which requires preliminary approval from Miami-Dade DERM before it will approve any work at or below the waterline; projects touching navigable water can also require U.S. Army Corps of Engineers and Florida DEP review, and the city's Board of Architects (plus Historic Preservation staff in historic districts) reviews anything visible from the water or street.
