The cumulative dredge volume including a 1- foot allowable over-dredge is approximately 244,678 cubic yards.
Dredging is expected to be done using barge-mounted mechanical equipment.
Dredged material will be placed in a hopper barge or dump scow for transport and disposal at yet to be constructed Portland Harbor confined aquatic discharge (CAD) cell.
The deadline for sending public comments on the proposed work is July 23, 2020.
