How much does residential canal dredging actually cost?

Mobilization starts at $3,000 and dredging starts at $150 per cubic yard. A typical single-slip job around 80 cubic yards lands near $15,000 all in. Larger basins or multi-lot projects scale from there.

What is the mobilization fee and why is it separate?

Mobilization covers getting the barge, excavator, support skiff, and crew to your dock and setting up the work zone. It's a fixed cost — the same whether we remove 40 yards or 400 — which is why splitting it across neighbors is the biggest single way to cut your bill.

Can I save money by coordinating with my neighbors?

Yes — this is the single biggest lever. Three or four neighbors splitting one mobilization and running back-to-back can cut per-homeowner cost by 20–30%. If a neighbor is even thinking about dredging, talk to them before you book.

What areas of South Florida do you serve?

We serve all of Palm Beach and Broward Counties, with specific expertise in Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, and Jupiter.

What pushes the per-yard price above $150?

Three things: restricted access (low bridges, tight finger canals), organic muck that needs landfill disposal instead of beach-nourishment reuse, and long trucking distances to an approved upland disposal site.

Canal Dredging Cost Palm Beach: 2026 Pricing Guide

Real 2026 numbers for canal dredging in Palm Beach County: mobilization starts at $3,000, dredging starts at $150 per cubic yard, and shared jobs cut your bill.

If you're a waterfront homeowner in Boca Raton or a marina manager in Jupiter, you've likely noticed the draft in your canal getting shallower every year. Silt, sand, and organic muck don't stop moving just because your boat is docked. Eventually, you're stuck waiting for high tide just to leave your lift.

At Palm Beach Dredging, the first question we get is always: "What is this going to cost me?"

Here's the honest 2026 answer, with the two numbers that actually drive your quote: mobilization and per-yard dredging.

The Two Numbers That Matter

Almost every residential dredging quote in Palm Beach County comes down to two line items:

Mobilization: starts at $3,000. This is the flat cost to get the barge, excavator, support skiff, and crew to your dock and set up the work zone. It's the same whether we pull out 40 yards or 400 — which is why small jobs feel expensive per yard and bigger jobs feel like a bargain.
Dredging: starts at $150 per cubic yard. This covers the actual cut, the spoil handling, dewatering, hauling, and disposal at an approved upland site. Pricing climbs from there based on access, sediment type, and disposal distance.

A typical single-slip residential job in Delray Beach or Boynton Beach — say 80 cubic yards around a dock and lift — pencils out around $3,000 mobilization + $12,000 dredging = $15,000 all in. Bigger basins or full canal frontages scale linearly from there.

What Drives the Per-Yard Price Up

The $150/cy floor assumes a clean, accessible job. These factors push it higher:

Access and Equipment

Open access: Wide canal in West Palm Beach with no low bridges? We bring in heavy equipment, work fast, and stay near the floor price.
Restricted access: Tight finger canals or anything behind a low fixed bridge means smaller, slower equipment — and more yards-per-day cost.

Sediment Type

Clean sand near inlets is the easiest material to move and sometimes qualifies for beach-nourishment reuse, keeping disposal cheap.
Organic muck ("black mayonnaise") in older inland canals has to be dewatered and trucked to a landfill. Disposal alone runs $25–$40 per yard before we touch the dredging line.

Distance to Disposal

Every extra mile to the approved disposal site adds trucking time. Properties farther from upland sites in western Palm Beach County will see the per-yard rate creep up.

Things to Plan Around (Not Priced Above)

A few items sit outside the mobilization + per-yard math but can affect your project:

Turbidity curtains. Required to keep sediment from drifting out of the work zone. Standard residential curtains are included; high-current locations (near inlets) sometimes need heavier-duty setups.
Seawall stability. If we dredge too close to an old seawall without a toe shelf or tie-backs, we risk a collapse. We'll flag this on the site visit if your seawall needs attention before dredging.
Post-dredge bathymetric survey. A signed survey after the job confirms restored depth — useful for resale and for your records.

Mobilization and Shared-Cost Opportunities

Mobilization is a fixed cost. The single best way to lower your per-property bill is to coordinate with neighbors on the same canal.

If four homeowners on the same block in Boca Raton all need dredging, the mobilization line gets split four ways — and the per-yard rate often drops 10–20% on top of that because we're working continuously instead of demobilizing between jobs.

Pro tip: If even one neighbor is talking about dredging, get on a call with them. We've seen per-homeowner costs come down 20–30% when three or more properties coordinate a single mobilization window.

When to Start Planning

The actual field work for a residential job is typically 2–5 days. The longer pieces are the site visit, bathymetric survey, and scope build-out — plan on 4–6 weeks from your first call to a barge in the water for a standard project, longer if neighbors are joining in.

Palm Beach Dredging specializes in the specific muck and sand profiles of South Florida. We don't just "dig holes" — we handle the engineering, the disposal logistics, and the heavy lift of restoration.
