Port of Tacoma to spend $1.5M on dredging for Blair Waterway

JOHN GILLIE has the story in the Tacoma News Tribune:

The Port of Tacoma plans to spend some $1.5 million to deepen water adjacent to one of its main containership terminals because sediments have restricted the terminal’s use.

Puget Sound pilots guiding ships into Husky Terminal on the port’s Blair Waterway warned the port in the summer of 2010 that several high spots on the waterway’s bottom were making it difficult to berth ships at the terminal. Later tests confirmed the pilots’ reports.

Those tests showed that sediment flowing from the nearby Puyallup River and scoured from the Blair channel by tugboats’ propellers and the bow thrusters of the ships passing down the waterway had reduced the depth along Piers 3 and 4 significantly.

The port’s lease with containership operator “K” Line requires the port maintain a water depth of at least 51 feet at low tide to allow the ships to tie up.
