The Dutra Group has been busy lately working on a beach renourishment project at Ocean Beach, SF.
For this project the company is using their trailing suction hopper dredge Stuyvesant to pump sand from the ocean floor up onto the beach.
This beneficial use project is being managed by the U.S. Army Corps of Engineers at the request of the City and County of San Francisco, in partnership with the Golden Gate National Recreation Area.
Overall, the Ocean Beach project includes construction of a sand berm on property owned by the Golden Gate National Recreation Area in front of 3,000 feet of bluff south of Sloat Boulevard using sand dredged from the San Francisco Main Ship Channel.
The goal is to protect the Great Highway and nearby wastewater infrastructure maintained by the San Francisco Public Utilities Commission’s (SFPUC).
According to the Corps, the beach nourishment is continuing as weather allows. Material placement is proceeding northerly from the center of the beach nourishment area.
At this time over 100,000 cubic yards of an estimated 250,000 CY of sand is in place on the beach. Completion of the northern half of the beach nourishment area will be followed by the start of beach nourishment of the southern half.
Placement of beach nourishment material is anticipated to be complete in mid to late September. Dredging of the Main Ship Channel and placement of dredged material on Ocean Beach is anticipated to continue 24 hours per day, 7 days per week until completion (weather and equipment permitting), concluded the Corps.
