Seawall Permitting in Miami & South Florida.

What seawall permitting actually involves

Almost nobody sets out to buy a permit. Owners set out to fix a failing wall, replace one that has reached the end of its life, or answer a notice from a county inspector — and then discover that the work sits behind a stack of approvals from agencies that do not talk to each other. A seawall is one of the few structures in South Florida that is simultaneously a building element, a shoreline modification, and an encroachment into waters the state and federal government both regulate. That is why permitting a seawall is a different exercise from permitting a driveway.

Souffront handles that path as an engineering task rather than a paperwork task. The same Florida-licensed structural engineer who evaluates the wall prepares the sealed drawings and calculations the reviewers are going to interrogate, and the same firm answers the comments when they come back. Nothing is handed off to a third party who has never seen the wall.

Which approvals your wall will need

The exact stack depends on where the wall is, what you are doing to it, and whether the work reaches below the waterline. A typical South Florida seawall project touches some combination of the following:

• Municipal building department. The structural permit for the wall itself — cap, panels, piles, anchorage — reviewed against the Florida Building Code and, in Miami-Dade and Broward, the High-Velocity Hurricane Zone provisions.
• Miami-Dade DERM, Class I permit. Required for coastal construction and shoreline work in Miami-Dade. This is the approval that historically governed the schedule of an entire project.
• Broward County environmental licensing. Shoreline and tidal-flood-barrier work is licensed at the county level, with the tier of license driven by the scale and impact of the work.
• Florida Department of Environmental Protection. Environmental resource authorization for work in or over surface waters, and separate authorization where the structure occupies state-owned submerged land.
• U.S. Army Corps of Engineers. Federal authorization for work in navigable waters — the layer that most often adds time when a project sits on the Intracoastal.
• Adjacent authorities. Right-of-way permits where a canal is bordered by public land, association or condominium approval where the shoreline is common element, and electrical permits where a lift or shore power is part of the scope.

Getting this stack right at the start is most of the job. The single most expensive mistake in seawall permitting is submitting to one agency a design that a different agency will later refuse — and discovering it four months in.

What a complete submittal contains

Reviewers reject incomplete packages far more often than they reject bad engineering. A complete seawall submittal generally includes:

• A current signed and sealed survey showing the property line, the shoreline, the control line where one applies, and existing structures
• Structural drawings signed and sealed by a Florida-licensed structural engineer — plan, sections, and connection details
• Structural calculations supporting the wall type, embedment, anchorage, and crown elevation
• Existing-conditions documentation: photographs, measured defects, and the engineering basis for repair versus replacement
• Confirmation of jurisdiction — which waterbody, whose submerged land, and which agencies therefore have standing
• Association or condominium approval where the shoreline is shared or common element
• Specifications for materials in a marine environment: concrete cover, mix, reinforcement protection, and anchorage hardware

How long it takes now

Timelines in Miami-Dade improved materially. Under the county reform ordinance approved in July 2025 and effective that December, the county must issue a decision on most Class I seawall and bulkhead permits within 90 days of the completeness summary, and applications are submitted through the county portal. Before that reform, owners routinely waited well over a year.

That clock only starts when the application is complete, which is the part an owner can control. A package that draws three rounds of comments has effectively chosen a longer schedule. Projects that reach federal waters should still expect additional review time on the Corps layer, and every schedule we publish to a client separates agency review time from construction time so nobody mistakes one for the other.

The design rules your permit will be tested against

Permitting is where shoreline elevation policy stops being abstract. In Broward County, new and substantially rehabilitated tidal flood barriers are held to a regional minimum of 4 feet NAVD88 for applications before January 1, 2035, and must be designed and built so they can be raised to 5 feet by 2050. The same standard treats tidal water crossing onto a neighboring property or the public right-of-way as a citable nuisance, which means a wall that is merely as tall as it used to be may not be approvable. Individual municipalities set their own minimum crown elevations on top of the county standard, and several waterfront cities sit above it.

The practical consequence for owners is that a major repair can trigger a height and design upgrade. It is far cheaper to learn that during design than after a rejection — and it is the reason our permitting work begins with an engineering assessment rather than an application form.

Permitting city by city — Miami Beach and the waterfront municipalities

County approval is only half the path. The city your wall sits in sets its own crown elevation and its own review, and the differences between neighboring municipalities are large enough to change a design.

• Miami Beach. The city requires new seawalls to be built to 5.7 feet NAVD, or to 4 feet NAVD if the wall is designed to support a future elevation of 5.7 feet. Miami Beach is one of our core markets, and it is the jurisdiction where the elevation requirement most often turns a like-for-like replacement into a redesign.
• Miami, Coral Gables, Coconut Grove, Key Biscayne, and Bal Harbour. Municipal review on top of Miami-Dade DERM, each with its own elevation and setback treatment along Biscayne Bay and the canal system.
• Fort Lauderdale and coastal Broward. City review layered onto Broward County environmental licensing and the county tidal-flood-barrier standard.
• Palm Beach, West Palm Beach, and Boca Raton. Municipal review with county and state authorization, and Intracoastal frontage that frequently brings in the federal layer.
• Key Largo and the Upper Keys. Monroe County review with its own shoreline and habitat constraints.

We permit across all of these. The governing elevation and the review path are established per property at the start of a project, rather than assumed from the last job we did one city over.

Violations, notices, and after-the-fact permits

A meaningful share of the permitting we handle starts with a notice rather than a plan: a county inspection that found unpermitted shoreline work, a wall built by a prior owner with no record behind it, or an open permit that was never closed and is now blocking a sale. These cases are won with documentation. We evaluate what is actually in the ground, produce the sealed drawings that describe it, and present a remediation scope the agency can approve — rather than arguing with a deadline.

What Souffront handles

• Jurisdictional determination — which agencies apply to your specific shoreline
• Survey coordination with a licensed surveyor
• Signed and sealed structural drawings and calculations
• Application preparation and submittal to every agency in the stack
• Comment response and resubmittal, handled by the engineer of record
• Association and adjacent-owner coordination where the shoreline is shared
• Inspections during construction and final permit closeout with sealed as-builts

The process

1. Assessment. A licensed structural engineer evaluates the wall and the shoreline and identifies every agency with standing.

2. Strategy and fixed fee. We map the approval path, the expected review time, and the cost — in writing, before you commit.

3. Drawings and calculations. Sealed structural documents prepared to satisfy the building department and the environmental reviewers together.

4. Submittal. Complete packages filed with each agency, sequenced so one approval does not invalidate another.

5. Comment response. The engineer who sealed the drawings answers the reviewer directly.

6. Closeout. Construction inspections, final sign-off, sealed as-builts, and a complete permit file you keep.

Engagement and pricing

Permitting is quoted fixed-fee against a defined approval path, not billed hourly against an open-ended one. Agency and review fees are passed through at cost and identified separately so you can see what is ours and what is the county’s. Where we also build the wall, permitting is folded into a single design-build contract — one firm accountable from the first assessment to the closed permit.
