Pacific Dredge & Construction performed maintenance dredging for the City of Pittsburg Public Works Department in October and November of 2019. Approximately 23,700 cubic yards of sediment was removed from the Pittsburg Marina Basin II (Lowy Basin). The sediment was removed to minimum elevation of -7.00 MLLW with a barge mounted Liebherr material handler using a 3 cubic yard CableArm environmental clamshell bucket and placed into 300 cubic yard split hull dump scows. Three dump scows were utilized for this job. A total 145 scow loads were delivered using the tugboat Tommy pushing three loaded scows per trip from Pittsburg Marina to the designated SF-9 Carquinez Straight Disposal Site.
