Redwood Dredging Starts Soon
The Redwood City navigation improvement project that will deepen the city harbor and San Bruno Shoal channels is about to begin.
The U.S. Army Corps of Engineers has signed a contract with RE Staite for channel operations and maintenance dredging. The $10.3 million scheme will start on November 15 and will operate 24 hours a day. The dredging is expected to be completed by late January but is authorized to go through March 1.
Also, the Port Commission recently approved a $1.5 million contract for ship berth operation and maintenance dredging at wharves 1-4 with the Dutra Group.
The scope of work for this project includes dredging the berths to a design depth of -34′ MLLW. It will begin on November 10 and finish around December 1.
The dredging program will restore the channel to its authorized depth of -30 feet for the first time since 2009.
Maintaining the channel at its fully authorized depth is critically important to increase the transpiration efficiency of the bigger Panamax vessels.
Also, deeper drafts for these ships mean they can make a few less port calls and still provide the same amount of construction materials. This lowers the air emissions in the Bay Area from these ships and the tugs that dock them in Redwood City.
