Quick answer

What are Fort Lauderdale's seawall height rules, and when do they apply to my property?

Since March 2023, Fort Lauderdale has required new and substantially repaired tidal flood barriers, including seawalls, to reach 5 feet NAVD88, or 4 feet if applied for before 2035 and designed to reach 5 feet by 2050. Florida Bulk Head accepts inquiries here and connects owners with a qualified participating contractor when one is available, subject to availability. Barefoot Marine Construction does not perform work here.

Fort Lauderdale's Tidal Waterfront

In parts of Fort Lauderdale, high tides already reach the street. In 2014 the city accepted state funds to install tidal valves in three Southeast Isles neighborhoods, Las Olas Isles, Venice Isle and Rio Vista Isles, because low road elevations let tidal water flow back from the adjacent canals through outfall pipes onto roadways during high tides. A Hendricks Isle resident told CBS News Miami in 2023 that her street has always been impassable during king tides.

The city has also moved to raise some of its own walls. A 2022 city memo approved an agreement to replace about 790 linear feet of public seawall along East Las Olas Boulevard and SE 10th Street, walls identified in the city's 2018 Seawall Masterplan, with corrosion-resistant steel sheet piles and a concrete cap at a top elevation of 5.0 feet NAVD88. On private lots, the 2023 ordinance puts the duty to keep a barrier in good repair on the property owner.

The Tidal Flood Barrier Rule

Ordinance C-23-05, passed on second reading March 23, 2023, created Section 47-19.13 of the city's Unified Land Development Regulations (ULDR), Resiliency Standards for Tidal Flood Protection. It struck the city's 2016 seawall standard, which had set a 3.9-foot NAVD88 minimum, and extended the elevation rule from seawalls to all tidal flood barriers, which the ordinance defines to include banks, berms, green-grey infrastructure, seawalls and seawall caps.

Key elevation terms in ULDR Section 47-19.13 (Ordinance C-23-05)
ItemRule
Minimum top elevation5 feet NAVD88 for new or substantially repaired or rehabilitated tidal flood barriers
Interim option4 feet NAVD88 for applications submitted before January 1, 2035, if the barrier is designed to reach 5 feet by January 1, 2050
Maximum top elevationThe FEMA base flood elevation or 6 feet NAVD88, whichever is lower; in an X zone, the natural ground elevation, unless that conflicts with the minimum
DocksA dock installed after March 23, 2023 generally may not sit higher than the maximum allowed barrier elevation. A dock on a new barrier that is not poured with the cap and does not block upland drainage may sit up to 12 inches above it, and a dock on an existing shoreline structure may not exceed 12 inches above that structure's top
WaiverThe City Engineer may grant a waiver of up to three years for properties whose principal structure has a habitable finished floor below 4.0 feet NAVD88; it ends when the term expires or the property changes hands

Know Your Numbers First

Elevations are in feet NAVD88, a survey datum, not height above the water. Before you collect bids, get a survey of your existing cap and ask your engineer for the FEMA base flood elevation on your lot, since it can set the maximum.

When the Rule Applies to an Existing Wall

Section 47-19.13 applies to new barriers, to substantial repair or rehabilitation of shorelines and shoreline structures, to fixed structures attached to a barrier such as docks, and to existing shorelines that let tidal water through. It does not apply to oceanfront beaches or shorelines seaward of the Coastal Construction Control Line. Substantial repair or rehabilitation means:

  • Any modification to the shoreline or a shoreline structure along more than 50 percent of the length of the property's shoreline, or
  • Any modification of an existing shoreline structure that exceeds 50 percent of its fair market replacement cost. For this test, docks, finger piers, piles and ancillary concrete footers are excluded, but concrete docks poured monolithically with the seawall cap are included.

Once a project crosses that line, the barrier must be built along the property's entire shoreline. Caps added to an existing wall must be at least as wide as the existing cap, and new barriers should adjoin neighboring barriers where practicable to close gaps. Vertical walls built in marine waters where no seawall existed before need natural limerock riprap or other approved habitat enhancement at the waterward face. The rule also covers the Melrose Park and Riverland Road annexed areas.

Repair Deadlines, Citations and Sale Disclosure

Owners must keep tidal flood barriers in good repair. A barrier is presumed in disrepair if tidal water flows unimpeded through it onto adjacent property or the public right-of-way, and failing to maintain it is a citable offense. After a citation, the owner must show progress within 60 days and complete repairs within 365 days. If the repair is substantial, the owner must design, permit, build and pass final inspection of a wall that meets the elevation standard within those 365 days.

A barrier built to the new standard that is still overtopped by tide is not treated as a public nuisance or citable offense. And contracts to sell real estate in tidally influenced areas of the city executed after March 23, 2023 must include a disclosure, in capitalized bold type, that the owner may be required to meet minimum tidal flood barrier elevation standards.

How the City Rule Fits Broward County's Standard

According to the city's 2023 staff memo, the Broward County Commission approved a countywide tidal flood barrier standard on March 31, 2020, and a county land use plan policy (2.21.7) required tidally influenced cities to adopt a consistent top elevation of 5 feet NAVD by February 13, 2022. Fort Lauderdale did not meet that deadline and kept the county informed until it adopted its ordinance. Staff wrote that much of the county ordinance was based on Fort Lauderdale's own 2016 seawall ordinance.

The road to adoption was not smooth. The memo records that the city's Planning and Zoning Board twice voted down motions finding the change consistent with the Comprehensive Plan, in September and November 2022, before the City Commission passed it. The Southeast Florida guide lists the other Broward cities staff named as having adopted the regional standard.

Living Seawall Permit Fee Assistance

On May 5, 2026, the City Commission adopted Resolution 26-78, creating a Living Seawall Permit Fee Assistance Program: a 100 percent discount on the city's base building permit fees for qualifying living seawalls, with an initial $50,000 fund and per-project caps of $3,500 for residential and $7,000 for commercial properties, first come, first served. At least 51 percent of the wall's length must carry permanent habitat-enhancing features on the waterward face, and the entire wall must be raised to the elevation required by Section 47-19.13. The discount does not cover Broward County or state fees, and the staff memo said the application would be posted on the city website on June 1, 2026.

Questions to Settle Before You Hire

Before you sign for Fort Lauderdale seawall work

  • Check the contractor's state license on the DBPR license search (opens in a new tab), and ask about liability, workers' compensation and, for work over navigable water, federal Longshore coverage.
  • Ask the designer to state the existing and proposed top elevations in feet NAVD88, the lot's base flood elevation and whether the job counts as a substantial repair.
  • If your finished floor is below 4.0 feet NAVD88, ask whether a City Engineer waiver applies before you settle on a height.
  • Ask which approvals the job needs (city, Broward County, DEP, Corps) and who applies for each.
  • If you want the living seawall discount, confirm the design meets the 51 percent living requirement before you apply.

Oceanfront beaches and shorelines seaward of the Coastal Construction Control Line are outside Section 47-19.13.

Local construction considerations

Substantial Repair Threshold

Work along more than half the shoreline, or exceeding half the structure's fair market replacement cost, triggers the 5-foot standard along the whole property.

Minimum and Maximum Heights

The top must reach 5 feet NAVD88, or 4 feet under the pre-2035 option, but may not exceed the base flood elevation or 6 feet, whichever is lower.

Low Finished Floors

Homes with a habitable finished floor below 4.0 feet NAVD88 may qualify for a City Engineer waiver of up to three years; the City Engineer weighs whether a barrier at the minimum height could flood the living space.

Habitat Enhancement

New vertical walls in marine waters where no seawall existed need limerock riprap or other approved habitat enhancement, and living seawalls can earn a permit fee discount.

Docks and Caps

New caps must be at least as wide as the existing cap, and docks installed after March 23, 2023 are tied to the barrier's allowed or existing top, with no more than 12 inches above it in the cases the code allows.

Common seawall concerns

  • King tide water coming through joints or around low caps onto neighboring lots or the street, which the code treats as presumed disrepair. See joint separation.
  • Walls built to the old 3.9-foot standard that must be raised once a repair becomes substantial.
  • Cracked caps and spalling concrete on older walls. See cracked caps and concrete spalling.
  • Fill washing out behind the wall and holes in the yard. See soil washout.
  • Leaning walls and failed tiebacks. See tieback failure.

Regional cost factors

  • How far the existing cap sits below 5 feet NAVD88 and whether the pre-2035 4-foot option fits your design.
  • Whether the work crosses the substantial repair threshold and must cover the whole shoreline.
  • Habitat enhancement or living seawall panels, and whether the permit fee discount applies.
  • Engineering, surveys and tie-ins to neighboring walls.
  • Dock and cap changes needed to meet the height and width rules.

Fort Lauderdale seawall and bulkhead questions

Does Florida Bulk Head have a contractor in Fort Lauderdale?

Not yet. Florida Bulk Head is building a partner network and accepts project inquiries from Fort Lauderdale. When a qualified participating contractor is available for your location and scope, we ask before sharing your details, and if none is available we tell you. Barefoot Marine Construction does not perform work in this region.

Do I have to raise my Fort Lauderdale seawall now?

Not simply because the standard changed. Section 47-19.13 applies to new barriers, substantial repairs and attached structures, and to walls cited because tidal water flows through them onto neighbors or the street. A city sustainability official told CBS News Miami in 2023 that the ordinance would not affect existing walls in good shape and of appropriate height.

What counts as a substantial repair in Fort Lauderdale?

Any modification along more than 50 percent of the length of the property's shoreline, or any modification exceeding 50 percent of the existing structure's fair market replacement cost. Docks, finger piers, piles and ancillary concrete footers are excluded from that cost test, but concrete docks poured monolithically with the cap count. A substantial repair must meet the elevation standard along the entire shoreline.

Can my Fort Lauderdale seawall be taller than 6 feet?

Generally no. The top of a new or modified tidal flood barrier may not exceed the FEMA base flood elevation for the property or 6 feet NAVD88, whichever is lower, and in an X zone the limit is the natural ground elevation, though the minimum elevation section governs if the two conflict.

What was Fort Lauderdale's seawall height before 2023?

The city's 2016 amendments set a minimum of 3.9 feet NAVD88 for new seawalls. Ordinance C-23-05 struck that standard and set 5 feet NAVD88, with the 4-foot option for applications before 2035, to match Broward County's regional standard. The new height applies to new barriers and substantial repairs, so ask the city before planning work on a wall built to the old minimum.
