Newport Harbor Dredging Project 2026: What the Work Leaves Behind

October 22, 2026

Since December, the derrick barge DB Point Loma has been working Newport Harbor with a small fleet around it. The Tug Killeen and the Tug Sagittarian tow the disposal scows Rob P. and Mike J. out of the harbor. The Jeanie R push boat, the John Drake work boat and a survey boat run errands in between. A Coast Guard Local Notice to Mariners dated Oct. 16, 2026 lists that whole lineup and says equipment demobilization is anticipated to be completed by Oct. 28, which is next Wednesday.

Once that equipment leaves, there won't be much to look at. Almost everything this project paid for sits on the harbor floor. The point was depth, and depth doesn't show from the shoreline. The Newport Beach Independent put it plainly: "few, if any, will ever see the physical result." If you spent this year watching the crane from a dock or a paddleboard, you watched the only visible part of it.

Nine Hundred Thousand Cubic Yards of Old River

The City of Newport Beach and the U.S. Army Corps of Engineers marked the start of the Newport Harbor Dredging Project at Marina Park on Tuesday, Nov. 4, ahead of dredging that was expected to begin on or about Dec. 10, 2025. According to the city's announcement, the plan was to remove about 900,000 cubic yards of sediment over 10 to 12 months. That would bring the harbor back to its federally authorized depths for the first time in decades.

Most of that material is old. The Independent reported that much of it came from the era when the Santa Ana River emptied into the bay at what is now the Turning Basin. Deep-draft commercial vessels were still delivering supplies there as late as the 1930s. The required depths are 20 feet in the main channel and 10 to 15 feet in the smaller channels. The paper estimated the total sediment could weigh close to two billion pounds. For comparison, it put the Empire State Building at 730 million.

The area covered is the federal channel system. The city's project page describes it as the Entrance Channel, then the Main Channel up to the Turning Basin, then the smaller channels that branch off it. The harbor has been under federal authority since the 1930s, so federal channels need federal partners. The Independent reported the project cost at $21 million, split between Newport Beach and the federal government.

Getting that money took lobbying. Public Works Manager Chris Miller oversees the harbor's capital projects. In the same Independent piece, he said the city "had to pledge a partnership with the Feds to contribute to the federal coffers, plus we had to overcome the image that Newport was just a pleasure harbor." His team's pitch to Congress called Newport the largest small boat harbor in the western U.S. and a regionally important harbor for shipyards, fuel docks and safe refuge. He gave credit to former City Council members Marshall "Duffy" Duffield and Brad Avery and to former Harbor Commissioner Scott Cunningham.

Why Part of the Pace Was Set in Long Beach

All that mud had to go somewhere, and part of the schedule depended on where. The city says about 80% of the material was cleared for ocean disposal at an EPA-permitted federal site roughly six miles offshore. The remaining 20% has elevated contaminants such as mercury. It goes by barge to the Port of Long Beach, where it is sealed in place to build new land for a shipping terminal project. The Coast Guard notice names the two destinations as the LA-3 Ocean Dredged Material Disposal Site and the Port of Long Beach Pier G facility.

Finding that out came first. The Independent reported that Newport spent more than a year and $1.3 million testing sediment before dredging began. That testing is how the contaminated share was identified. The Long Beach option also came with a deadline. According to the same report, the city sped up dredging in the upper reaches of the bay, sometimes working seven days a week, to meet the fill timelines set by the Long Beach project managers. So for anyone who heard the crane running on a weekend, a container terminal 20 miles up the coast set part of that schedule.

Here is how the dates lined up:

Milestone Date Source
Pre-dredge surveying and diving begin Oct. 23, 2025 Coast Guard notice
Launch event at Marina Park Tuesday, Nov. 4 City of Newport Beach
Equipment mobilization scheduled Dec. 8, 2025 Coast Guard notice
Dredging expected to start On or about Dec. 10, 2025 Coast Guard notice
Contractual completion, as reported in April Around Sept. 26, 2026 Newport Beach Independent
Equipment demobilization anticipated By Oct. 28, 2026 Coast Guard notice dated Oct. 16, 2026

The last two rows mark different milestones. The April report put contractual completion around late September. The October notice gives Oct. 28 as the date the equipment should be packed up and gone.

Where the Bucket Has Been

The Log reported in December 2025 that work began near the western end of Lido Isle. In April, the Independent described a 24-cubic-yard bucket at work and reported that the scows' capacity totals 3,000 cubic yards. Miller told the paper that contractor R.E. Staite Engineering "may very well be ahead of schedule."

The best mid-project update came in the August 2026 Lido Isle News, which carried an update from Miller. Crews had finished the area next to Newport Harbor Yacht Club. That stretch took much longer than the others because there was so much material in it, and moorings were due back in their original positions the following week. By then, 262 disposal scows had carried 541,000 cubic yards out of Newport Harbor, about 60% of the project total.

The same update said crews were heading back to the channel between the eastern tip of Lido Isle and Marina Park. They had partly dredged it months earlier to reach material between Marina Park and the 19th Street public pier. For the second pass, they brought out a different bucket. It holds less but is much heavier, with steel teeth on the cutting edges so it can get through a harder bottom known to exist in that channel. Some things stayed put on purpose. The Independent reported that native eelgrass and other marine life had to be left in place, with constant monitoring to make sure of it.

Sharing the Water Until the Barge Leaves

Until demobilization is done, the Coast Guard notice and Miller's newsletter update give the same basic guidance for anyone on the water:

  1. Stay at least 300 feet away from the dredging equipment.
  2. Pass at your slowest safe speed to keep your wake down.
  3. Arrange passage before you go by. The equipment monitors VHF-FM Channel 16, and the Lido update says the dredger also monitors Channel 01.
  4. Give the tugs and scows extra room. The Lido update singled out junior sailing programs, yacht clubs, race committees and rowers, because a loaded scow carries enough weight and momentum that it can't change course quickly.

The notice also lists a temporary mooring buoy for the project that rotates among three locations in the harbor.

Why This Should Be the Last One This Size

The 2012 dredging is the reason people call this one "the last." The city describes the current project as the final phase of a harbor restoration program that goes back decades, including dredging projects completed in 2012. The city also expects no more comprehensive harbor dredges after this one. Sediment control in the Upper Bay and across the watershed has greatly reduced how much material reaches the Lower Bay, so future work should be small-scale maintenance.

So the depth this project restores has a good chance of lasting. The deposits came from a river mouth and a working port a century ago, and the Upper Bay controls are slowing new silt from coming in. The Independent passed along Miller's view that it may be decades before Newport sees another major dredging operation.

Dredging at private and commercial docks is a separate matter. Small maintenance projects at docks, floats and piers have been handled under their own Corps permit program, known as RGP-54, which went through a renewal process in 2025. That program is not part of the federal channel project. Questions about a specific dock belong with the city and the Corps.
