Boating from Seven Isles: Bridges, Clearances & the Route to Port Everglades

By Glen Primak, GLEN PRIMAK GROUP · Updated

Not for navigation. This is a plain-English summary of published federal sources as of October 23, 2026. Bridge rules change by Federal Register notice, and posted clearances are measured at specific tide datums. Always check the current eCFR text, Coast Guard Local Notices to Mariners, the bridge clearance boards, and an up-to-date NOAA electronic chart before you go.

The short answer

From a Seven Isles dock, the usual way to the ocean is south on the Atlantic Intracoastal Waterway (ICW) to Port Everglades. That run passes two bascule (opening) bridges: the East Las Olas Boulevard Bridge and the SE 17th Street (Brooks Memorial) Bridge. There are no fixed bridges on this route. If your boat clears a bridge in its closed position, you can pass at any time. If it doesn’t, you wait for that bridge’s scheduled opening.

Sources: 33 CFR 117.261(y) and (z) (eCFR, current); Federal Register 2026-00932; Coast Pilot 4, Ch. 12 (Oct 18, 2026 ed.); USCG Federal Register 2012-8873 (Las Olas 24 ft).

Step by step: Seven Isles to the Atlantic

  1. Leave the canal for the ICW. The Intracoastal borders Seven Isles to the east and north, so every canal in the neighborhood opens onto it within a short distance. Canal widths, depths, and turning room differ from lot to lot. Check depth at your dock and along your canal at low tide, with a survey if needed. Don’t rely on a general guide for this.
  2. Head south to the East Las Olas Bridge (ICW mile 1064.0). Coast Pilot 4 lists a reported 24-foot center clearance for this bascule span. The Coast Guard’s 2012 rulemaking gives the same 24-foot closed figure. Under 33 CFR 117.261(y), the draw opens on signal on the quarter-hour and three-quarter hour. One seasonal exception applies: on the first weekend in May, the draw need not open from 4 to 6 p.m. Saturday and Sunday, or from 9:45 to 10:45 p.m. on that Saturday.
  3. Continue past Bahia Mar. Coast Pilot places the Bahia Mar Yachting Center about 0.4 mile south of the Las Olas bridge on the east side. You also pass the mouth of the New River to the west.
  4. Pass the SE 17th Street (Brooks Memorial) Bridge (ICW mile 1065.9). It is a twin bascule with 55 feet of vertical clearance at mean high water when closed (Federal Register 2026-00932; Coast Pilot 4 lists an authorized 55 ft at center). Under 33 CFR 117.261(z), it opens on the hour and half-hour. The exception is weekdays (except federal holidays) from 6:50 to 9:10 a.m. and 3:50 to 6:10 p.m., when it opens only once an hour, at the top of the hour.
  5. Enter Port Everglades (ICW mile 1066.3) and run out the inlet. Commercial traffic, cruise ships, and security zones are common here. Monitor the harbormaster on VHF Ch. 14, keep clear of large vessels, and watch posted manatee and slow-speed zones.
Under 33 CFR 117.261, public vessels of the United States and tugs with tows are passed through at any time. Any vessel that fits under a bridge in its closed position may pass at any time; you don't need an opening.

What the clearances mean for your boat

  • Under 24 ft air draft (many center consoles and smaller express cruisers, depending on arch, T-top, and antennas): you can usually pass under both bridges without an opening, subject to the tide and the boards.
  • 24–55 ft: you pass under the 17th Street bridge but need a Las Olas opening, which happens at :15 and :45.
  • Over 55 ft (larger sportfish with towers, sailboats with tall masts): you need both bridges to open. Plan around the 17th Street weekday rush-hour limit (top of the hour only).

Bridge clearances are published at a stated datum, usually mean high water. Actual clearance falls on spring tides and king tides, so read the clearance boards on approach. To request an opening, hail the bridgetender on the listed channel or use the sound signal in 33 CFR 117.15.

Heading north instead

Northbound boaters on the ICW meet the East Sunrise Boulevard bascule bridge and others on the way to Hillsboro Inlet. Their schedules are also set in 33 CFR 117.261. Check the current text before relying on a time.

Charts and publications to keep aboard

  • NOAA Electronic Navigational Charts (ENC). NOAA canceled its traditional paper/raster charts for this area, including 11466, 11467 and 11470, on April 3, 2024. Use current ENC data in a chartplotter or NOAA’s chart-viewing tools.
  • U.S. Coast Pilot 4 (Chapter 12 covers the ICW through Fort Lauderdale, and Chapter 10 covers Port Everglades). It is free from NOAA and updated weekly.
  • Coast Guard Local Notices to Mariners for temporary bridge deviations, for example during events.

Dock and seawall rules

These are the City of Fort Lauderdale rules most relevant to a Seven Isles dock or seawall, from the Unified Land Development Regulations (ULDR) as amended by Ordinance C-23-05 (adopted March 23, 2023). They are a summary, not legal or engineering advice. Confirm the current code and permit requirements with the City before any project.

Seawall height (ULDR Sec. 47-19.13)

  • A new seawall, or one being substantially repaired or rehabilitated, must work as a tidal flood barrier with a top elevation of at least 5 feet NAVD88.
  • Applications submitted before January 1, 2035 may be permitted at 4 feet NAVD88, if the wall is designed to reach 5 feet NAVD88 by January 1, 2050.
  • “Substantial repair” means work on more than 50% of the length of the property’s shoreline, or work costing more than 50% of the structure’s replacement value. That work must run along the property’s entire shoreline.
  • The top of a new or modified barrier may not exceed the FEMA base flood elevation or 6 feet NAVD88, whichever is lower.
  • Owners must keep seawalls in good repair. If tidal water flows through or over a wall onto a neighbor’s property or the street, the City can cite the owner. The owner must then show progress within 60 days and finish within 365 days.
  • Contracts to sell property in tidally influenced areas of the city must include a specific tidal flood barrier disclosure.

Docks, lifts and how far you can extend (ULDR Sec. 47-19.3)

  • Docks attached to a new or rebuilt seawall may sit up to 12 inches above the maximum allowed barrier elevation, if they are not poured as one piece with the seawall cap and don’t block water draining over the cap.
  • Docks, lifts and similar mooring structures may not extend into the waterway more than 25% of its width or 25 feet, whichever is less, measured from the property line. Mooring or dolphin piles may extend up to 30% of the waterway width or 25 feet, whichever is less.
  • A dock or lift needs a principal building on the lot.
  • Lifts and davits: one per the first 100 feet of lot width, plus one more for each additional 100 feet. A second one on a lot between 100 and 200 feet wide needs Site Plan Level II approval. One personal-watercraft lift is allowed in addition. Lifts may be no more than 6½ feet above lot grade, and a hoisted boat’s lowest point may sit no more than 1 foot above the seawall cap.
  • Boat length and side setbacks: a boat docked behind a home may not extend past the side setback lines for the house, extended out into the water. This is often what actually limits boat length on a canal lot.
  • No boathouses or boat covers in the required setback area or over a public waterway.

Boating questions to ask about a specific Seven Isles lot

  • Is the frontage on the Intracoastal or on an interior canal? How wide is the canal at the dock, and how much room is there to turn?
  • What is the depth at mean low water at the dock and along the canal, by survey?
  • What dock, lift and seawall permits are on file with the City of Fort Lauderdale, and what condition is the seawall in, by inspection?
  • How long a vessel fits within the lot’s side setback lines extended into the water, and how far a dock or lift can extend under the 25%-or-25-feet rule? See dock and seawall rules above.
