Project Detail

Project: Chollas Creek Dredging
Owner: U.S. Navy
Start date: 5/23/1997
Finish date: 11/14/1997
Value: $3,006,475

Maintenance dredging of 100,000 CY of sandy muck, excavating with a derrickbarge/clamshell dredge and loading a pocket scow barge and offloading with an onshore, longreach hydraulic excavator, and loading trucks for off base upland disposal. The project also required the building of a confined disposal facility (CDF), for dewatering and temporary storage of the dredge spoils, adjacent to the scow offloading area. By employing the use of watertight, sidedump tractor/ trailer hauling units, we were able to skip the intermediary step of using the CDF, resulting in a quicker completion, and less impact on Naval Operations.
