Dredging News

Port of Port Angeles plans to pursue an estimated $700,000 berth maintenance dredging project for its cargo terminal, Terminal 3.

The work is planned to dredge about 6,300 cubic yards of material from the berth area, bringing the seafloor to about 45 feet below sea level.

The pier is used by two companies to transport debarked logs from the Olympic Peninsula to markets in China.

Last year, 15 cargo vessels were loaded at the pier and transported 84 million board feet of logs overseas, providing $2.35 million in revenue for dockage, wharfage, and service.

There are two options for what to do with the dredged material, ranging from disposing of the sediment in the water to disposing of it upland.

One option would have dredged material placed on port property. The other upland option, estimated to cost $2.5 million, would have had the sediment disposed of at a landfill in Eastern Washington or Oregon.

It was estimated the project would take about two weeks and that permitting for the project will take about eight months.

Solicitation Number: W912WJ-17-B-0005

Notice Type: Solicitation

Work Description:
The work involves urgently needed dredging of two portions of the authorized, 27-foot deep, 500-foot wide FNP in the lower Kennebec River. Dredging would restore the channel to its authorized dimensions and involves removal of a total of about 70,000 cubic yards (cy) of clean sand. Approximately 50,000 cy of material will be removed from the Doubling Point area (i.e. just below Bath) and approximately 20,000 cy of material will be removed from the Popham Beach area (at the river mouth). The 50,000 cy to be removed from the channel at Doubling Point includes approximately 35,000 cy of advance maintenance dredging. Material dredged from the Doubling Point area will be placed in the previously used in-river disposal area north of Bluff Head in about 95-100 feet of water. Material dredged from the Popham Beach area will be placed in the previously used 500-yard diameter nearshore disposal area located about 0.4 nautical miles south of Jackknife Ledge and in about 40-50 feet of water.

The U.S. Army Corps of Engineers has decided to rehire Manson Construction Co. of Seattle to handle the dredging of the Oceanside harbor.

Manson had done the work for several years until 2016 when the Army Corps chose another contractor — CJW Construction of Santa Ana — to conduct the dredging. The work dragged on for months, city officials said, obstructing parts of the harbor entrance and nearby beaches during the busy tourist season.

CJW had problems in part because an extended vetting process prevented it from starting the work on time. The dredging work is typically finished by Memorial Day — the last Monday in May — but last year the job began in June and ended in October.

The dredging contract with CJW cost $5 million last year, and the 2017 contract with Manson is expected to cost about the same.

Manson will stage its bulldozers, pipes, and other equipment, and work could begin in another week or two. The dredging project is to have all the work done before Memorial Day.

The man-made municipal harbor requires annual dredging to remove the sand that ocean currents constantly deposit at the entrance. As the mouth of the harbor fills with sand, the shallower water increases the size of incoming waves, making the navigation more hazardous for boaters.

Dredging lowers the depth to more than 20 feet at the entrance to keep boats safe during low tides and high swells.

Sand dredged from the harbor is piped in a seawater slurry onto beaches south of the harbor beginning at about the North Coast Village condominium complex. Sometimes, depending on the amount of sand dredged and the conditions of the beach, it could be spread past the city pier.

Manson’s larger dredge has two main advantages over smaller equipment, Federer said. One is that it is more efficient and can move more sand in less time, and the other is that its size is less subject to sea swells and other ocean conditions.

The Oceanside harbor, built at a cost of $7 million, opened in 1964 with 520 boat slips.
