Bridge Clearances And Dock Basics In North Palm Beach

Owning a boat or shopping for a waterfront home in North Palm Beach brings one big question to the surface: will your vessel actually fit your lifestyle and local waterways? Between bridge clearances on the Intracoastal and the realities of docks, lifts, and seawalls, small details can shape daily convenience and long-term value. In this guide, you’ll learn how to verify bridge heights, plan safe passages, understand dock permitting, and review seawalls and insurance like a pro. Let’s dive in.

North Palm Beach waterways at a glance

North Palm Beach sits on the Lake Worth Lagoon and the Intracoastal Waterway, with many homes fronting canals or basins connected to the ICW. You can run north toward Jupiter, south toward West Palm Beach, or plan routes that connect to the Atlantic via the Lake Worth Inlet. Tides here are modest compared with other regions, but even a small tidal swing can affect whether a tall boat clears a bridge. Storm surge and long-term sea-level trends also matter, so it pays to watch tide predictions before you go.

Bridge clearances 101

Fixed vs movable bridges

You’ll encounter two bridge types locally: fixed bridges with a set vertical clearance, and movable bascule bridges that open on request. Your planning depends on which you face. Fixed bridges require your vessel to pass under at the available height, while movable bridges require you to follow posted procedures for radio or phone contact and timing.

Vertical clearance vs air draft

• Vertical clearance is the height from the water surface at a reference tide to the bottom of the bridge structure.
• Air draft is your boat’s height from the waterline to its tallest fixed point, including radar arches, antennas, solar panels, or dinghies on davits.
• The published clearance is tied to a tidal datum, so the real clearance changes with the actual tide stage. When margins are tight, a few inches of tide can be decisive.

How to verify bridge info

• Measure your air draft with the boat loaded as you normally run it.
• Check official nautical charts for charted bridge clearances and confirm the tide datum that applies.
• Review U.S. Coast Guard publications for bridge details, temporary restrictions, or construction advisories.
• Confirm the bridge owner or operator’s current opening hours, procedures, and VHF channel or phone number posted for each movable bridge.

Transit timing and safety

• Time your passage for a favorable tide if you run tall. Build in extra margin for wave action and wake.
• Never try to “sneak” under a bridge when you lack clear clearance.
• Watch for overhead utility lines in canals. They can be lower than bridges and are easy to overlook.
• Follow posted no-wake zones and channel markers. Local rules are actively enforced.

Dock and permitting basics

Who permits docks and lifts

Private dock work in North Palm Beach can involve multiple authorities. The Town’s building and engineering departments handle local permits. Palm Beach County Environmental Resources Management oversees shoreline and coastal structure permitting at the county level. Projects that affect tidally influenced waters can require state review by the Florida Department of Environmental Protection, and work in navigable waters can trigger U.S. Army Corps of Engineers permits. Requirements vary by scope, location, and whether you are replacing in kind or expanding.

Riparian rights and easements

Waterfront owners often hold riparian rights that allow reasonable access to navigable waters. Those rights are still subject to municipal, county, state, and federal rules, plus any recorded easements, HOA covenants, or shared community dock agreements. Confirm what is recorded before you assume you can build or expand a private dock.

Common dock components

Most local docks use a fixed pier layout with finger piers, piles, cleats, and utilities. Treated timber piles are common, while concrete or steel piles may be used for longevity or heavier loads. Boat lifts are popular to reduce fouling and provide storm protection, and they require structural and electrical compliance. Material choices affect maintenance cycles, cost, and what treatments are permitted in the water.

Seawalls and erosion control

A seawall’s condition directly influences safety, value, and insurability. Look for signs of movement, cracking, voids, or sinkholes. Review any available design standards, permits, or inspection records, including details such as pile depth and scour protection. A tired seawall can restrict financing or increase insurance hurdles, so plan ahead if a replacement may be needed.

Maintenance and safety

Expect periodic replacement of decking and hardware, treatment or replacement of piles, and regular service for boat lifts. Electrical systems should be installed and maintained by licensed professionals using code-compliant wiring and GFCI protection. A marine survey or certified dock inspection helps quantify remaining life and prioritize repairs before listing or purchase.

Insurance and liability

Tell your insurer about docks and lifts so coverage can be structured correctly. Flood and wind or hurricane coverage are separate considerations, and flood insurance is typically necessary in coastal flood zones. You may also want to review liability coverage and any safety requirements such as ladders or rescue equipment.

Hurricane preparation

Before a storm, secure loose items and lock down lifts according to manufacturer guidelines. Follow local evacuation guidance for vessels. If a property has weathered multiple storms, consider an engineering review to understand how the dock, piles, and seawall match current design expectations.

Due diligence checklists

Buyer checklist

• Request property disclosures for the dock, boat lift, and seawall, including any as-built drawings.
• Gather permits from the Town, County, State, and U.S. Army Corps for original work and later repairs.
• Obtain recent inspection or engineering reports for the seawall, pilings, and lift.
• Review maintenance records and date-stamped photos of major repairs or replacements.
• Confirm recorded easements, riparian rights, or community dock agreements, plus any HOA rules.
• Check flood zone, elevation certificates, and expected flood insurance costs.
• Measure your vessel’s air draft, map likely routes, and review local bridge clearances and opening procedures.
• Check recent U.S. Coast Guard notices for construction or temporary restrictions.
• Ask about dredging history, channel markers, and any known submerged hazards at the property.

Seller checklist

• Compile permits, as-built plans, inspection reports, and maintenance records for easy buyer review.
• Disclose any unpermitted structures or past notices of violation.
• Clarify any agreed-upon dock, lift, or seawall repairs that will be completed before closing.

FAQs

How do bridge clearances work on the ICW in North Palm Beach?

• Fixed bridges have a published vertical clearance tied to a tide datum, and movable bridges open on request under posted procedures. Always measure your boat’s air draft, check charts and current notices, and factor the actual tide stage before transiting.

How do I measure my boat’s air draft accurately?

• Measure from the waterline to the tallest fixed point with the boat in normal loaded condition. Include antennas, radar, solar panels, and dinghies if they sit higher than the arch or cabin top.

Do I need a permit to replace a boat lift or piles in North Palm Beach?

• In-kind minor repairs may be exempt, but boat lifts, structural replacements, piling work, and expansions usually require permits. Check with the Town, Palm Beach County Environmental Resources Management, the state, and the U.S. Army Corps before you begin work.

What should I review on a seawall before I buy?

• Look for movement, cracking, settlement behind the wall, and evidence of scour. Ask for permits, inspection records, and any engineering reports to understand remaining life and possible upgrades.

Will my homeowners policy cover dock damage from storms?

• Coverage varies. Flood and storm surge are often excluded from standard policies and may require separate flood insurance. Confirm details with your carrier and consider liability coverage for dock use.

Can I plan ocean access from North Palm Beach?

• Yes, many local routes use the Intracoastal Waterway with proximity to the Lake Worth Inlet. Your actual plan depends on your boat’s air draft, bridge clearances, and current operating procedures for any movable bridges along the route.
