Newport’s Big Harbor Dredge Isn’t the Whole Story. The Mud Under Your Dock Is Still Yours.

The giant Lower Newport Bay dredging job has been the harbor’s main event. But anyone with a slip off Balboa Island, Lido or the Peninsula knows the channel isn’t the only spot that gets shallow.

On Nov. 5, the city’s Water Quality/Coastal Tidelands Committee parked two harbor items for future meetings. One is the Lower Bay dredging project’s completion. The other is in-harbor nearshore dredging, sediment testing and RGP-54. There was no discussion and no vote. The committee also proposed skipping December, which would make the next meeting Jan. 7, 2027.

RGP-54 is the city-run permit that lets dock and pier owners do small maintenance dredging without starting from scratch with every agency. According to a 2025 Water Board notice, the limits are:

  • work between the bulkhead and pierhead lines
  • down to 10 feet below mean lower low water, plus a 2-foot allowance
  • up to 8,000 cubic yards per project
  • 75,000 cubic yards a year harbor-wide

The city fee is $1,810 this fiscal year, plus a $200 state certification check. Approval takes roughly 60 to 90 days once the application reaches the agencies.

The catch is the mud itself. Keeping RGP-54 valid has required re-studying the harbor’s nearshore sediment every five years. In July 2025, the city applied to renew the permit with no changes. The city’s website still lists the Army Corps permit dated 2020, and we haven’t confirmed whether the renewal is final.

Translation for dock owners: the big dredge is its own city project. The shallow water under your boat runs on a separate permit, a separate process and your fees.

When this comes back in January, the questions are simple. Is the permit current? Is new testing coming? And who pays for it?
