Manson to Complete Oakland Harbor Dredging in November

The Oakland Harbor maintenance dredging project will be completed before the end of November, reports Manson Construction Co. of Seattle, Washington.

As reported, this project includes annual maintenance dredging of the Oakland Inner and Outer Harbor federal navigation channel.

The contracting agency – the Army Corps’ San Francisco District – estimates that this project will dredge approximately 756,000 cubic yards of material to a depth of -50-ft MLLW plus 1-foot of allowable paid over-depth.

Most of the material excavated from the Inner and Outer Harbor will be used for wetlands restoration, habitat enhancement, and upland construction projects in and around San Francisco Bay.

The works are being performed by Manson’s derrick barge NJORD assisted by tender JEFFREY M.

Dredging season is restricted to this time period to protect endangered fish and fowl.
