Florida Seawall GuideDescribe My Seawall Problem

Choosing a Florida seawall contractor

We do not maintain a list of companies and we do not refer you to anyone. What follows is what to ask, and what should make you slow down.

Before anything else: This site is an independent research resource. We are not a contractor, we do not perform work, and we do not employ crews. We have no roster, no partners on this page, and nothing to gain from which company you choose.

Seawall work is unusually hard to shop, because the thing being priced is largely invisible. You cannot see the toe, the embedment or the anchoring, which means you are comparing proposals about a structure none of you has fully observed unless someone got in the water.

The questions below are ordered to surface that gap early.

Six questions worth asking

  1. 01Which agencies will need to review this work, and who is filing?

    Permitting can involve the city or county, FDEP, the regional water management district and the U.S. Army Corps of Engineers depending on scope and waterway. The answer tells you whether the company has done work like yours before.

  2. 02What minimum elevation applies to my property, and what is your source for it?

    In South Florida this is a published number that differs between neighbouring cities. A company that cannot cite the requirement for your jurisdiction is guessing about the most consequential design input.

  3. 03Is this being treated as a repair or a substantial repair?

    In Broward County that distinction is defined and it triggers elevation requirements. Getting it wrong changes both the scope and the permit path.

  4. 04Has anyone examined the toe of the wall and the mudline?

    Most of the structure and most failures are below the waterline. A scope written from a walk along the cap is a scope written from the smaller half of the evidence.

  5. 05What happens if the soil behind the wall is worse than expected?

    Voids and washed-out fill are the usual reason a price changes mid-project. Ask how that is handled before it happens, not after.

  6. 06Is the anchoring system included, and how was that decided?

    Tiebacks are buried and expensive. Published figures put full panel plus tieback replacement at the top of repair ranges. A quote that is silent on anchoring is silent on the largest variable.

Things that should slow you down

  • A per-linear-foot price given before anyone has assessed water depth, access and soil

    Those three inputs are among the largest cost drivers. A number produced without them is a marketing position.

  • No mention of permitting, or an assurance that no permit is needed

    A statutory exemption from one agency is not an exemption from all of them. Florida Statutes § 403.813 explicitly does not supersede Chapter 161 requirements.

  • Certainty about your required elevation without naming the ordinance

    The requirement differs by city. Fort Lauderdale, Pompano Beach and Miami Beach publish three different numbers.

  • Pressure created by a deadline that is not attributed to a document

    Real deadlines exist and are citable. Broward County has a transition date of January 1, 2035 written into its ordinance. If a deadline cannot be pointed to, treat it as a sales device.

  • The inspection and the proposal are the same document

    That may be perfectly fine, but you should know which you are holding. An assessment and a bid have different purposes.

The documented facts behind those questions

GENERAL RANGEGEN-AGENCIES

Seawall permitting can involve several agencies at once, depending on scope and waterway.

  • Depending on the project, review may involve the city or county building department, the Florida Department of Environmental Protection, the regional water management district, and the U.S. Army Corps of Engineers.

Read carefully: Which agencies apply is determined by your specific waterway and scope of work, not by your city alone.

Florida statute exempts seawall restoration from certain state permitting, but the exemption is measured in inches.

  • Section 403.813(1)(e) exempts "the restoration of seawalls at their previous locations or upland of, or within 18 inches waterward of, their previous locations."
  • Section 403.813(1)(o) exempts the construction of private seawalls in wetlands or other surface waters when the construction is between and adjoins at both ends existing seawalls, follows a continuous and uniform seawall construction line with the existing seawalls, is not more than 150 feet in length, and does not violate existing water quality standards, impede navigation, or affect flood control.
  • Neither exemption supersedes permitting requirements under Chapter 161.

Read carefully: An exemption from one agency is not an exemption from all of them. A project can be exempt under 403.813 and still require city, county, water management district or Army Corps authorisation.

Broward County defines when a repair is large enough to trigger the elevation standard.

  • A "substantial" repair or rehabilitation has occurred when more than 50% of a property's shoreline structure is modified.
  • It is also triggered when an attachment — a mooring, for example — valued at more than 50% of the cost of installing a tidal flood barrier on the property is installed.

Read carefully: The second trigger is the one owners miss. Adding a valuable attachment can pull an otherwise routine project into the elevation standard.

Cape Coral changed its seawall alternative permitting requirements for applications dated on or after January 1, 2022.

  • Where there is an existing vertical bulkhead seawall immediately adjacent to a proposed alternative seawall slope, signed and sealed plans by a Florida-registered professional engineer must accompany the application, including construction details for retaining walls installed or extended at 90 degrees to the existing seawall and securely attached for erosion control.
  • Where there is no adjacent vertical bulkhead, an as-built survey prepared by a Florida-licensed surveyor must be available on site for the inspector, showing the elevation at the property line abutting the waterway and the controlling weir sill elevation, and verifying the installation does not extend past the property line.
  • Alternative designs adjacent to a seawall must install a securely attached wing wall for erosion control. Placing fill in the canal to avoid this requirement is not permitted.
  • Construction stakes must be on site so inspectors can visually confirm the slope does not extend above the water past the property line into the canal right of way.

Questions we can answer from sources

What licence does a seawall contractor need in Florida?
We did not find a single authoritative statement covering every jurisdiction and scope, so we do not publish one. What we can confirm is that some jurisdictions require the design itself to be sealed by a professional engineer registered in Florida — Cape Coral requires it for the freshwater seawall alternatives it publishes standards for. Verify licensure directly with the state and your local building department.
How many quotes should I get for seawall work?
We do not have evidence supporting a specific number, and we do not collect quotes for you. What is more useful than a quote count is making the quotes comparable: establish the required elevation, whether the work is a substantial repair under local definitions, and whether anchoring is included, before comparing any two prices.
