The Port of Tacoma says it expects to seek bids in December for a plan to deepen the water around one of its main containership terminals. The action is being taken, according to the port, to counter an increase in sediment from the nearby Puyallup River, which has been collecting along piers 3 and 4.
According to the port’s lease with containership operator “K” Line, there’s a mandated water depth of at least 51 feet at the terminal during low tide so that ships can tie up. But with that stipulation not currently being met, “K” Line has adjusted its containership schedules so that its ships usually call on Husky Terminal during higher tides.
The dredging activities, which are expected to eliminate silt from a half-mile long, 150 foot wide area at a cost of about $1.5 million, are due for completion by mid-February, according to the port.
The dredged sediment and other materials are expected to be placed in either on land or a deep-water disposal area.
