The Last Big Dredge at the Tip of Lido Isle

The crane parked off the western tip of Lido Isle since last December is about as rare as anything Newport Harbor offers. The Christmas Boat Parade, which starts and ends on that same stretch of water this December, comes back every year. The dredge, by the city's own forecast, may not come back for decades.

The U.S. Army Corps of Engineers started dredging the federal channels of Lower Newport Bay in early December 2025. The plan was to remove about 900,000 cubic yards of sediment over roughly 10 months. The Orange County Register reported that the contractor began at the western tip of Lido Isle. The Newport Beach Independent put the contract's completion target around September 26 of this year. The city's public timeline still says "fall 2026." The agenda for the October 1 meeting of the city's Water Quality/Coastal Tidelands Committee listed "Lower Bay Dredging project completion" among its items. The committee's next scheduled meeting is Thursday, November 5. Taken together, the project is in its last stretch, and the formal wrap-up is still ahead.

Last December, the Parade and the Dredge Shared the Water

When the dredge arrived last year, it showed up right before the harbor's busiest week. During the 2025 Christmas Boat Parade, the contractor said it would stop dredging at 4 p.m. and move its barge and equipment to staging areas, according to the Register. The same report said boats in commercial slips along Coast Highway that stuck out into the work zone were asked to leave their slips for the day dredging took place next to them.

That was the deal for most of this year. A working harbor ran a dredge around a recreational one, and the tip of Lido sat where the two met. The parade's official route puts the 2026 start and finish at the Tip of Lido Isle. So this December, the start line sits on water that has just been dug down to its authorized depth.

Where Ten Months of Harbor Bottom Went

The sediment is old. Public Works Manager Chris Miller told the Newport Beach Independent that most of it is "legacy" material. Much of it was laid down back when the Santa Ana River emptied into the bay at what is now the turning basin. The dredge used a 24-cubic-yard bucket. Tugs towed scows holding 3,000 cubic yards each about six miles offshore.

The material went two ways:

1. Clean sediment went to LA-3, the federally permitted ocean disposal site. Testing found most of the material suitable for it.
2. Sediment unfit for ocean disposal was barged to the Port of Long Beach's Pier G Slip Fill project. There it is sealed inside an existing slip to create more container storage.

The earlier plan for that second batch was a Confined Aquatic Disposal pit, an underwater hole about 47 feet deep holding roughly 191,000 cubic yards. It would have sat between Lido Isle and Bay Island. That plan stalled, and in January 2025 the City Council approved disposal in Long Beach instead, as the Daily Pilot reported. The harbor's contaminated mud left the harbor. It is not buried in it next to the island.

The Long Beach option came with a schedule Newport did not control. The Independent reported that the city sped up dredging in the upper reaches of the bay, sometimes seven days a week, to meet the fill timelines set by Long Beach project managers. Getting there took real money. More than a year and $1.3 million went into sediment testing before the bucket ever touched the water. The dredge itself cost $21 million, split between Newport and the federal government.

Why Nobody Expects to See This Again Soon

The city calls this the last comprehensive dredge planned for the harbor. The previous major dredging projects wrapped up in 2012. Miller made the longer-range call to the Independent, and the paper summed it up in its lede:

"Look now, because it may be decades before Newport residents, boaters and visitors will ever again see a major dredging operation in Newport Harbor."

The goal is depth. Per the Independent, the main channel is held at 20 feet and the smaller channels at 10 and 15 feet. Those are authorized targets, not depths measured after the work. The dredge was also expected to leave native eelgrass in place, with crews monitoring throughout. Then-Mayor Joe Stapleton called it "a milestone project for Newport Beach" at the November 4, 2025 kickoff at Marina Park, as the Newport Signal recounted.

The Water in Front of a Lido Dock Is a Different Story

All of this covers the federal channels, from the Entrance Channel up the Main Channel to the Turning Basin at the Newport Boulevard bridge, plus their offshoots. The rest of the harbor falls to the City of Newport Beach, the County of Orange or private parties. The water between a private Lido dock and the channel edge is not part of the federal project.

Small maintenance dredging in designated harbor areas goes through the city's RGP-54 program. The city's dredging permit page lists a permit fee of $1,810 effective July 1, 2026. It estimates 60 to 90 days from agency submission to an approval notice. That same page still names a 2024 intake cycle, so the current filing window is a question for Public Works directly.

Caulerpa is the other factor. The California Department of Fish and Wildlife lists China Cove, Collins Isle and Linda Isle as the known Newport Bay locations of the invasive algae. It reports treatment at those sites and no new growth in recent surveys. NOAA's Caulerpa page, updated August 26, 2026, says eradication and survey work in Newport is ongoing. Lido is not on the detection list. Even so, Newport Bay is classed as an "Infected System" under the Caulerpa Control Protocol, Version 5, dated October 20, 2021. Under that version, bottom-disturbing work there requires two surveys of the project area at least 60 days apart, one of them within 45 days before work starts. The protocol counts bulkhead repair, pile driving and dredging as bottom-disturbing work. Its private-dock repair exemption applies only in Caulerpa-free systems. We share this as general information, not legal or permitting advice. Anyone planning dock or bulkhead work should confirm the current requirements with the city, NOAA or CDFW and their own marine contractor.

December Puts the Tip Back on Display

With the barge gone, the tip of Lido goes back to its best-known job. The 118th Christmas Boat Parade runs December 16 through 20, 2026. It leaves at 6:30 p.m. each night from the Tip of Lido Isle and returns there to finish. Boats head out from Lido's east end, and Marina Park is the first public viewing spot on the route.

The Ring of Lights is open to waterfront homes, businesses and yacht clubs. It also has its own "Best on Lido" category. The official winners archive lists the 2025 winner, and the category goes back at least to 2016. The Independent's 2024 recap placed that year's winner on Via Lido Nord, and the same homeowner took the title again in 2025.

Last year the parade fleet passed a dredge that had stopped at 4 p.m. and moved aside for the evening. This year it should start on finished channel. If you are mapping your own December around the island, our Lido Isle neighborhood guide and last summer's look at how the island's walking radius changed cover the shore side.

For a Lido Isle homeowner, the harbor floor is part of what you own: depth at the dock, permit timing and whether the bulkhead work can wait until spring. The Carter Kaufman Team follows these harbor projects because they come up in waterfront negotiations.
