U.S. Army Corps approves Columbia River channel deepening
The U.S. Army Corps of Engineers has approved a $136 million channel deepening project for the Pacific Northwest’s Columbia River.
The Corps will begin work improving the federal navigation channel that stretches 103 miles between the Pacific Ocean and Portland, Ore., and Vancouver, Wash. It will also involve the restoration of several ecosystems.
The Corps estimates that the project investment will return a $1.66 benefit for every dollar spent on the dredging project.
