Boating from Harbor Beach: Lake Sylvia, the Intracoastal & Port Everglades

By Glen Primak, GLEN PRIMAK GROUP · Updated October 24, 2026

The short answer

Harbor Beach sits at the south end of Fort Lauderdale’s barrier island, on the Intracoastal Waterway (ICW) just north of the SE 17th Street (Brooks Memorial) bridge and Port Everglades. Its canal lots sit on finger canals and on Lake Sylvia (named “Sylvan Lake” in the City’s GIS), which opens west to the ICW, and some lots, including on Isla Bahia, face the ICW directly. The usual way out is to the ICW, south through the 17th Street bascule bridge (55 ft vertical clearance at mean high water when closed), and out the Port Everglades inlet. That is one of the shortest runs to the ocean of any Fort Lauderdale canal neighborhood. Controlling depths and any road bridges over interior canals are not published here; check your canal’s route and its depth at low tide on a current NOAA chart and a survey.

Step by step: Harbor Beach to the Atlantic

1. Leave your dock and head for the ICW. From a canal lot, that means running your canal to Lake Sylvia or straight to the waterway. Check depth at your dock and along the route at low tide, with a survey if needed.
2. Turn south on the ICW. The 17th Street Causeway bridge is the south edge of the neighborhood.
3. Pass the SE 17th Street (Brooks Memorial) Bridge (ICW mile 1065.9). Under 33 CFR 117.261(z) it opens on the hour and half-hour, except weekdays (other than federal holidays) from 6:50 to 9:10 a.m. and 3:50 to 6:10 p.m., when it opens only at the top of the hour. Boats that fit under it in the closed position can pass at any time.
4. Enter Port Everglades (ICW mile 1066.3) and run out the inlet. Commercial traffic, cruise ships and security zones are common. Monitor the harbormaster on VHF Ch. 14 and watch posted manatee and slow-speed zones.

What the clearances mean for your boat

• Under 55 ft air draft: you can usually pass under the 17th Street bridge without an opening, subject to the tide and the clearance boards.
• Over 55 ft: you need a 17th Street opening. Plan around its weekday rush-hour limit.
• Heading north on the ICW: the East Las Olas bascule bridge (ICW mile 1064.0) has 24 ft closed at center and opens at :15 and :45, under 33 CFR 117.261.

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.

Anchoring in Lake Sylvia

Lake Sylvia is a well-known anchorage. Florida’s statute on anchoring limitation areas (s. 327.4108) does not list it among the designated areas as of October 24, 2026; a 2021 bill that would have added it (SB 1652) was not enacted. State rules on anchoring near docks and marinas still apply, and local rules can change, so check with Broward County and the City before you anchor.

Charts and publications to keep aboard

• NOAA Electronic Navigational Charts (ENC). NOAA canceled its traditional paper and raster charts for this area in 2024; use current ENC data.
• U.S. Coast Pilot 4: Chapter 12 covers the ICW and New River through Fort Lauderdale; Chapter 10 covers Port Everglades.
• Coast Guard Local Notices to Mariners for temporary bridge deviations, for example during the Fort Lauderdale International Boat Show.

Dock and seawall rules

These are the City of Fort Lauderdale rules most relevant to a Harbor Beach 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 Harbor Beach lot

• Does the dock face a canal, Lake Sylvia or the ICW? How wide is the water 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 route to the ICW, by survey? Are there fixed road bridges between the dock and the waterway?
• 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.
