Pacific Dredge & Construction (PDC) got awarded this project again and returned to Moss Landing during fall 2020 and reached completion before Jan 15,2021. Pacific Tugboat Service (PTS) provided their tugboat “Contender” to tow PDC 2,000 cu yds capacity scow to the disposal site (SF-14) offshore located at the Monterrey Bay. In-Harbor PTS supplied truckable tug “Cadet” and tug “S. Bass”.
The project consisted of the dredging of two reaches that were located in the Southern Harbor of Moss Landing. Dredging depth was -15 MLLW with 2 foot of allowable over-depth.
Reach 1 was mechanically dredged with our PDC 180 barge, crawler crane Manitowoc 4600 and combination of a 17 cu yd environmental clamshell bucket and a extra heavy duty digging bucket. Approximately 16,000 cu yds was dredged from Reach 1 and disposed of offshore at the approved disposal site (SF-14) in Monterrey Bay.
Reach 2 was mechanically dredged with our PDC 180 barge, crawler crane Manitowoc 4600 and environmental clamshell bucket. Approximately 52,000 cu yds was dredged and disposed of offshore at the approved disposal site (SF-14) in Monterrey Bay.
PDC set up all standard and specific BMPs to comply with all required site conditions. One of the site conditions is to have a mammal monitoring qualified firm in charge of observing Southern Sea Otter and Tidewater Goby in a daily basis for the duration of the project.
