Queensway Bay - Los Angeles River Estuary Dredging January to April 2008

 

Beginning Monday January 28, 2008, the United States Corps of Engineers will be conducting maintenance dredging to clear the navigation channel to the Catalina Express terminal in Queensway Bay.  The dredging will extend from a few hundred yards seaward of the Queensway Bay Bridge to the mouth of the Catalina Express Basin.  The channel was closed for several months after a severe storm in January 2005, and was reopened only at minimal operating width in the spring of 2005.  This maintenance dredging has been planned for some time, but is also timely, as the channel has been closed again due to storms earlier this month.

 

The dredge is a clamshell dredge, which is a large digging bucket at the end of a crane.  The material is then scooped from the bottom of the channel and placed on a barge that will transport the dredged material to one of three disposal locations, based on the nature of the material.  The beach quality sand will be taken to a near beach location off of Junipero Avenue and deposited offshore in about 20 feet of water.  Bay currents will then bring it to the beach helping to maintain beach width.  The non-beach quality material will be either deposited in the Port of Long Beach or offshore of the Palos Verdes Peninsula in a federally approved disposal location.  The bottom of the barge opens to deposit the material.

 

The dredging plan is to work 24 hours a day, seven days a week in order to shorten the length of the dredging period.  It is not anticipated that the dredging operations will create enough noise to be a disturbance.  However, if a disturbance occurs, please contact the chief inspector of the Corps of Engineers, Richard Ciranny, at (310) 521-1300 x 12 (office), (310) 521-1233 (fax), (562) 762-5427 (cell), or richard.ciranny@usace.army.mil to report the disturbance.
