Pacific Dredge Moss Landing Dredging Project a Success
Pacific Dredge & Construction (PDC) is returning to Moss Landing to dredge approximately 74,000 cubic yards of sediment after being awarded the project that is contracted to be completed before the end of 2020. In conjunction with the United States Corps of Engineers, PDC will break the new Moss Landing dredging project up into two reaches with a dredging depth of 15 MLLW with one foot of over-depth.
This is the second Moss Landing dredging job for PDC in the last year after completing a large dredge in the North and South Harbors of Moss Landing that yielded upwards of 65,000 cubic yards of sediment. When another mechanical dredging project was needed, PDC stepped up again and will begin work this fall.
Where is Moss Landing?
Sitting on Monterey Bay, Moss Landing combines an industrial and academic community with a thriving tourism industry 15 miles north-northeast of Monterey, California. Moss Landing features one of most unusual and vibrant ecosystems on Earth, making it ideal for whale watching, sports fishing, and other nature adventures, and is home to prestigious research facilities at California State University and the Monterey Bay Aquarium.
Moss Landing Mechanical Dredging, Pacific Tugboat Service
Pacific Dredge & Construction will use state-of-the-art dredging hydraulics, pumps, and excavators to clear the water of built-up mud and silt to keep the waterway clear for commercial and recreational vehicles. Pacific Tugboat Service will employ the “Contender” and the “Cadet” to tow materials to a disposal site at Monterey Bay.
PDC will set up all standard and specific BMPs to comply with required site conditions. Among the site conditions is to have a mammal monitoring qualified firm in charge of observing Southern Sea Otter and Tidewater Goby on a daily basis for the duration of the project.
Reach 1 will undergo mechanical dredging with the PDC 180 barge, crawler crane Maintowoc 4600, and an environmental clamshell bucket. This portion of the project has an estimated quantity of 22,000 cupid yards that will be disposed of offshore at the Monterey Bay.
Reach 2 is estimated to dredge 52,000 cubic yards that will also be disposed of offshore at the Monterey Bay.
Prior Moss Landing Dredging Project Yields 65K Cubic Yards of Sediment
From October 2019 to January 2020, PDC removed about 65,000 cubic yards of mud and silt from the North and South Harbor in Moss Landing. The sediment in the harbor was removed to minimum elevations of -10’ and -12’ MLLW. Two 200 cubic yard dump scows and 8,000 feet of 12” pipeline was for the project.
A hydraulic cutter suction head dredge and booster pump removed 17,000 cubic yards of sediment from the North Harbor, while 48,000 cubic yards was dredged in the South Harbor using a 10” Eddy Pump excavator attachment to a hydraulic cutter suction head dredge, and a barge-mounted Liebherr material handler using a 3-cubic yard environmental clamshell bucket.
