The permitting process for new seawalls in Broward and Palm Beach is the part of a waterfront project owners least anticipate and least control. A wall sits on sovereign submerged lands, in or beside navigable water, within an environmental resource system, and under a local building department, which means four reviewers with different questions, different timelines, and no obligation to coordinate with one another. Knowing the sequence is what keeps the calendar intact.
Key takeaways
- Who reviews a new seawall?
Four levels, usually concurrently: the municipal or county building department for the structure; the county's marine, environmental, or shoreline division; the state, through the Florida DEP, for sovereign submerged lands and environmental resource permitting coordinated with the water management district; and federal reviewers where the work reaches navigable waters. - What does the state review cover?
The Florida state review of a new seawall covers two things: authorization to occupy sovereign submerged lands, since the state owns the bottom below the mean high water line, and an environmental resource review of impacts to water quality, seagrass, mangroves, and protected habitat. - Where does federal review enter?
Where the structure occupies or affects navigable waters of the United States, which covers most Intracoastal and canal frontage connected to navigable channels. - What does a complete application package contain?
A complete seawall application in Broward or Palm Beach contains a signed and sealed survey showing property lines, the mean high water line, and existing structures; engineered drawings with plan, sections, embedment, tie-backs, cap, and drainage details; geotechnical data; a construction plan showing access, staging, and turbidity controls; environmental resource information; and adjacent-property tie-in details.
Who reviews a new seawall?
Four levels, usually concurrently: the municipal or county building department for the structure; the county’s marine, environmental, or shoreline division; the state, through the Florida DEP, for sovereign submerged lands and environmental resource permitting coordinated with the water management district; and federal reviewers where the work reaches navigable waters. Oceanfront parcels add coastal-line jurisdiction on top.
The permitting process for new seawalls starts with building review, administered by Broward County and Palm Beach County.
What does the state review cover?
The Florida state review of a new seawall covers two things: authorization to occupy sovereign submerged lands, since the state owns the bottom below the mean high water line, and an environmental resource review of impacts to water quality, seagrass, mangroves, and protected habitat. The two are coordinated, and a wall aligned to the existing structure generally draws fewer questions than one placed waterward of it.
The state half of the permitting process for new seawalls is published by Florida DEP, with district review by the South Florida Water Management District.
Where does federal review enter?
Where the structure occupies or affects navigable waters of the United States, which covers most Intracoastal and canal frontage connected to navigable channels. The Army Corps of Engineers reviews under its own authorities, sometimes through streamlined pathways for routine replacement work, and habitat and species considerations can extend the timeline.
The federal layer of the permitting process for new seawalls sits alongside waterway and wildlife rules from FWC.
What does a complete application package contain?
A complete seawall application in Broward or Palm Beach contains a signed and sealed survey showing property lines, the mean high water line, and existing structures; engineered drawings with plan, sections, embedment, tie-backs, cap, and drainage details; geotechnical data; a construction plan showing access, staging, and turbidity controls; environmental resource information; and adjacent-property tie-in details. Completeness at first submittal is the only variable an owner truly controls.
The permitting process for new seawalls rewards complete engineering, covered in hurricane-resistant seawall design standards.
How does the permitting process for new seawalls actually run?
The permitting process for new seawalls in Broward and Palm Beach runs in six steps: survey and engineering assessment; design against agency criteria; simultaneous submittal to state, federal, county, and municipal reviewers; response to comment cycles from each; issuance with conditions; then construction under those conditions with inspections and closeout documentation. Submitting sequentially instead of simultaneously is the most common self-inflicted delay.
Once the permitting process for new seawalls closes, the construction that follows is described in seawall construction and permitting.
Does replacement permit faster than new construction?
Seawall replacement in South Florida usually permits faster than new construction, when the replacement stays in the existing footprint or alignment: reviewers treat in-kind replacement more routinely than a wall pushed waterward or a new structure where none existed. Refacing an existing wall can be simpler still. Any change in alignment, height, or footprint reopens questions that alignment-matching avoids.
Alignment decides how heavy the permitting process for new seawalls becomes, and the repair-versus-replace judgment is in seawall maintenance, repair, and replacement costs.
What conditions typically attach to a permit?
The conditions that typically attach to a Florida seawall permit are turbidity barriers and water quality monitoring during construction; manatee and marine wildlife protection measures; seasonal or in-water work windows; restoration of disturbed areas; specific inspection points; and as-built survey submission at completion. Conditions are enforceable obligations, and treating them as paperwork is how projects fail closeout.
What delays applications most often?
Seawall applications in South Florida are delayed most often by five things: incomplete or unsealed submittals; surveys that omit the mean high water line or submerged-lands boundary; designs proposing alignment waterward of the existing wall without justification; unresolved tie-in conditions with neighboring properties; and applications filed sequentially rather than in parallel. All five are avoidable at the desk, before anything is submitted.
Every delay in the permitting process for new seawalls is avoidable at the desk, and front-end discipline is covered in the South Florida luxury home permitting process.
How does Kass Construction & Development manage approvals?
By opening the slowest track first: Kass Construction & Development, a state-licensed (CGC1529472) boutique luxury builder led by Mitch Kass, a licensed general contractor and attorney, with 100+ luxury residences delivered by Mitchell Kass and the firms he has led across Broward, Palm Beach, and Miami-Dade, runs the permitting process for new seawalls in parallel with residence design so marine approvals never become the critical path by surprise.
A custom build often runs 18 to 36 months, with the shoreline file opened at the start. Contact Kass Construction & Development or call 954-607-4335.
How does the permitting process for new seawalls differ between Broward and Palm Beach?
The permitting process for new seawalls shares its state and federal layers across both counties, but the county and municipal layers are organized differently, and the table below sets the two side by side.
| Element | Broward County | Palm Beach County |
|---|---|---|
| County environmental reviewer | Environmental Engineering and Permitting Division, with an environmental resource license for work at or below mean high water | Environmental Resources Management, with county review of shoreline and submerged land work |
| Municipal building permit | City building department (Fort Lauderdale, Pompano Beach, Lighthouse Point and others) issues the structural permit and inspects | Municipal or county building department depending on location (Boca Raton, Delray Beach, Jupiter, unincorporated areas) |
| Minimum cap elevation | County ordinance sets a minimum top-of-wall elevation in NAVD 88 for new and replacement tidal seawalls, with the figure scheduled to rise; municipalities may require more | Municipal rules vary; many coastal cities have adopted minimums; confirm per city |
| State role | Florida DEP for sovereign submerged lands and any environmental resource permit not delegated; CCCL on the ocean | Same |
| Federal role | Army Corps of Engineers for navigable waters, usually under a general permit for residential seawalls and docks | Same |
| Species conditions | Manatee protection zones and construction conditions in most waterways | Manatee conditions plus sea turtle nesting season on the ocean and Intracoastal in places |
| Typical sequence | County environmental license, then city building permit, with state and federal running in parallel | County environmental review and municipal permit, with state and federal in parallel |
State submerged land and environmental resource rules are published by the Florida Department of Environmental Protection, water management district rules by the South Florida Water Management District, and manatee protection guidance by the Florida Fish and Wildlife Conservation Commission. The agency map for the whole region is in seawall construction and permitting in South Florida.
What does a complete application for a new seawall contain, in order?
The permitting process for new seawalls moves fastest on a complete package, and the list below is the order in which the documents are produced and filed.
- Signed and sealed survey showing property lines, the mean high water line, the existing wall, adjacent walls and cap elevations in NAVD 88.
- Engineer’s condition assessment of the existing wall and a statement of the failure mode, where a replacement is proposed; the symptoms are described in the seawall maintenance cost guide.
- Geotechnical report with borings behind the wall.
- Signed and sealed structural drawings of the wall, tie-backs, cap and drainage, designed to the standards in hurricane-resistant seawall design standards and showing the proposed cap elevation against the county minimum.
- Site plan showing the wall location relative to the property line and the water, any encroachment into submerged land, and the dock and lift.
- Environmental documentation: seagrass and benthic survey where required, mangrove locations, turbidity control plan and species protection plan.
- Proof of ownership and, where the wall sits on state land, the sovereign submerged land authorization application.
- Contractor license and insurance, verifiable at myfloridalicense.com, and the municipal permit application with fees.
What delays the permitting process for new seawalls, and how is each delay avoided?
The permitting process for new seawalls stalls for a short list of reasons, and each one has a fix that belongs in the preparation stage.
- Survey without the mean high water line or in the wrong datum: order the survey to the reviewers’ specification before anything else.
- Cap elevation below the current minimum: confirm the county and municipal figure at the outset and design above it, with the long-term context in sea-level rise in waterfront infrastructure design.
- Wall proposed waterward of the existing alignment: place the new wall at or landward of the old one unless the submerged land authorization is in hand.
- Seagrass or mangroves within the work area: survey early and design around them, since mitigation adds months.
- Missing turbidity and manatee plans: include them in the first submittal.
- Waiting for approvals in series: file state and federal applications in parallel with the county, and open the slowest first, as described in the South Florida luxury home permitting process.
- Uncoordinated dock and house permits: submit the seawall, dock and building permits as one coordinated set so conditions do not conflict.
Kass Construction & Development manages seawall approvals in Broward and Palm Beach as part of the overall waterfront program, so the wall is permitted and built before the house foundation depends on it.
Frequently Asked Questions
What permits does a new seawall require?
A local building permit with engineered drawings, county marine or environmental review, state authorization for sovereign submerged lands coordinated with environmental resource permitting, and federal review where navigable waters are involved.
Why does the state join the permitting process for new seawalls?
Because the land below the mean high water line is sovereign submerged land owned by the state, so any structure occupying it requires state authorization regardless of who owns the upland.
Is replacing faster than building new?
Generally yes, when the replacement matches the existing alignment and footprint. Moving a wall waterward or changing its dimensions reopens review questions that in-kind replacement avoids.
Should I apply to all agencies at once?
Yes. Reviews run in parallel, so simultaneous submittal compresses the calendar substantially. Filing sequentially adds each review’s duration to the total instead of overlapping them.
What is the mean high water line?
The surveyed boundary between privately owned upland and state-owned submerged land. It determines where state authorization is required and belongs on every seawall survey.
What conditions come with approval?
Commonly turbidity control, marine wildlife protection, seasonal work windows, restoration of disturbed areas, defined inspections, and as-built survey submission at completion.
Can I start work while permits are pending?
No. Unpermitted shoreline work invites enforcement, restoration orders, and lasting complications on the property record, and it is one of the few waterfront mistakes that is genuinely difficult to unwind.
