Port of Port Angeles outlines seawall/Cofferdam rehab and on-site biofiltration for stormwater

Port of Port Angeles grants staff gave a brief project update to the Clallam MRC on a rehabilitation plan for an existing Cofferdam facility along the western side of Port Angeles Harbor. The port representative said the work will replace the current Cofferdam with a fiberglass sheet wall at the port’s intermodal handling and transfer facility where barges load and unload cargo.

The port representative said the project is rehabilitation of the existing barge-handling facility rather than an expansion to accept larger vessels, and that dredging is not included in the current work scope. The port said the rehabilitation will include a three-stage biofiltration stormwater treatment system designed to treat stormwater from the intermodal facility operations.

Port staff said construction is anticipated to take place next summer and that the port will coordinate with technical staff and grant partners on finer engineering details. The grants representative invited committee members to reach out for more detailed engineering or funding information and said the port is considering additional stormwater and response investments following the Indian Creek spill discussion.

The committee did not take formal action on the port update; port staff described project scope, timeline and funding structure and offered to provide more detailed materials to committee members who requested them.
