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.
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?
Two things: authorisation 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 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?
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?
Usually, 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 judgement is in seawall maintenance, repair, and replacement costs.
What conditions typically attach to a permit?
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?
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 neighbouring 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 over 25+ years 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 14 to 24+ months, with the shoreline file opened at the start. Contact Kass Construction & Development or call 954-607-4335.
Frequently Asked Questions
What permits does a new seawall require?
A local building permit with engineered drawings, county marine or environmental review, state authorisation 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 authorisation 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 authorisation 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.
