Seattle Harbor Deepening Project Receives Corps Leadership Approval

The Seattle Harbor Navigation Improvement Project is eligible for congressional authorization following U.S. Army Corps of Engineers Commanding General Lt. Gen. Todd T. Semonite signing the Chief of Engineers Report on June 7.

The project proposal includes deepening the East and West Waterways to 57 feet below mean lower low water and if it receives authorization and funding for construction will improve navigation in Seattle Harbor’s East and West Waterways.

“This project will make the Port of Seattle the deepest container port in the nation at 57 feet deep,” said Port of Seattle Commission President and NWSA Managing Member Courtney Gregoire. “This is another step forward to making T-5 big ship ready, and able to handle the largest cargo vessels in the world. The Port of Seattle and The Northwest Seaport Alliance thank the Army Corps of Engineers for their timely completion of this study and recognition of the value the project will contribute to our nation.”
