Bulkhead Construction in Florida

What Bulkhead Construction Involves

A bulkhead is a retaining wall at the water's edge. Its main job is to hold the soil of your yard in place where the water in front of it is relatively calm: a residential canal, a protected stretch of river, a creek or a lake. Building one means installing a wall that resists the push of wet soil behind it and keeps enough support at its toe when the water drops.

Whatever the material, most new bulkheads in Florida are built from the same basic parts:

• Sheet piles or panels driven, vibrated or jetted into the bottom so that enough of the wall sits below the mudline to resist overturning.
• A cap, usually reinforced concrete, that ties the top of the wall together and keeps it in line.
• Anchors on anchored (rather than cantilevered) walls: tie-back rods running to a buried concrete deadman, or an engineered alternative such as helical anchors, that stop the top of the wall from rotating toward the water.
• Filter fabric and backfill that let water pass while keeping sand from washing out through joints.
• Drainage relief, such as weep holes or a gravel drain, so rain and high-tide water behind the wall do not build up pressure.
• Return walls at the property lines that tie into a neighbor's wall or turn back into the bank, so water cannot work around the ends.

Bulkhead or Seawall: Why the Distinction Matters

In Florida the words bulkhead and seawall are used almost interchangeably, and many permit forms and city codes use seawall for most vertical waterfront walls. The engineering difference is about load. A bulkhead is designed mainly to retain soil where waves are small. A seawall is designed to take repeated wave impact, overtopping and storm surge on a more exposed shoreline. Local usage varies too: Palm Coast's technical manual calls walls set in the water seawalls and walls set above mean high water bulkheads, while noting both are built the same way.

A wall on a quiet dead-end canal and one facing a wide reach of the Intracoastal Waterway can look alike, but the second usually needs more attention to wave loads, toe scour and height. If your shoreline faces open water or a busy channel, read Seawall Construction as well, and see Bulkhead vs. Seawall for the background.

Materials That Suit Florida Canals, Rivers and Lakes

Material choice starts with the water. Salt and brackish water carry chlorides that attack steel, including the reinforcing inside concrete; Fort Lauderdale's seawall master plan notes that chloride ions in seawater corrode reinforcing steel, which then cracks and spalls the concrete. Freshwater lakes avoid most of that, but their levels can swing and expose the toe of a wall. Florida's sandy soils move easily through any gap, so filter fabric and tight joints matter with every material.

Where the bank is gentle and the water is calm, a living shoreline or riprap revetment may stabilize the shoreline without a vertical wall. For estuaries and lagoons, Florida law states an intent to encourage riprap and gently sloping, planted shorelines over vertical seawalls (section 373.414(5), Florida Statutes). For a deeper comparison, see Types of Seawalls.

How a Contractor Evaluates the Site

A new bulkhead is designed from site information. Expect a contractor, and for most new walls a Florida-licensed professional engineer, to look at the following.

Permits for a New Bulkhead

New walls generally get closer review than repairs or replacements of existing ones. In Florida, a new bulkhead can involve several layers of approval:

• State environmental review. Environmental Resource Permits are handled by the Florida Department of Environmental Protection (FDEP) or one of five water management districts, under operating agreements; FDEP generally handles work serving one single-family home not part of a larger development.
• Exemptions with conditions. Section 403.813, Florida Statutes, exempts seawalls in artificially created waterways from state permits when they will not violate water quality standards, impede navigation or affect flood control. That exemption does not apply to vertical seawalls in estuaries or lagoons unless the work is within an existing man-made canal already lined in whole or part by vertical seawalls, and section 373.414(5) limits permits for new vertical seawalls there to a few situations. Exemptions also do not remove the need for permission to use state-owned submerged lands.
• Federal review. Work in navigable waters can require U.S. Army Corps of Engineers authorization. Jupiter's seawall checklist, for example, lists Corps approval alongside the state exemption verification.
• Local building permit. Cities and counties typically require one, often with engineer-sealed plans.
• Wildlife protections. In-water work in manatee habitat commonly carries standard manatee protection conditions; the Florida Fish and Wildlife Conservation Commission notes some projects also need observers or seasonal limits.

What Shapes the Scope of a New Bulkhead

Three decisions move the scope of a new bulkhead most: how tall the wall must be, how it is anchored, and how equipment reaches it. A short wall on an open lot with land access is a very different job from a tall wall behind a finished house where everything arrives by barge. Surveys, engineering and permit preparation are real parts of the scope, not extras. See Project Planning and the Florida Bulkhead Cost Report.

Preparing for a Quote and What to Ask

Questions to Ask Any Contractor

• Is your Florida contractor license active, and what type is it? You can confirm it on the state's DBPR license search (opens in a new tab).
• Who prepares the engineering, and will the plans be signed and sealed by a Florida-licensed professional engineer?
• Which permits do you expect, and who applies for them?
• What material and profile are you proposing, and why for this site?
• How will the wall be anchored, and where in my yard will deadmen or anchors go?
• What removal and restoration of landscaping, irrigation and hardscape is included in writing?

Bulkhead Construction in Northeast Florida and Across the State

In Northeast Florida, bulkhead construction requests are handled directly by Barefoot Marine Construction of Jacksonville, the company that owns and operates Florida Bulk Head. Barefoot serves Duval, St. Johns, Nassau, Clay, Flagler and Putnam counties. That area spans the tidal lower St. Johns River and its creeks, the Intracoastal Waterway, the saltwater canals of Palm Coast and freshwater frontage upriver and on area lakes, and local rules differ. Palm Coast's technical manual (dated 2009, revised 2010; confirm the current version with the city) allows vertical bulkheads only on its saltwater canals, in reinforced concrete, vinyl or aluminum with a concrete cap at 2.5 feet NAVD 88 or matched to abutting caps, and calls for 10-foot end returns where no neighboring wall exists. Jacksonville's 2023 Resilient Jacksonville strategy lists planned actions to limit new bulkhead permits on private property and to set height standards for privately owned bulkheads; check whether any have been adopted into city rules before design starts. See Northeast Florida.

Elsewhere in Florida, Florida Bulk Head is building a network of independent contractors. Requests from other regions are accepted, and matching is subject to contractor availability; no partner contractor has been confirmed in any region yet.
