Record RCC Structure Is Set for Groundbreaking in California
Mobilization has begun in Southern California for excavation of the foundation of what authorities are calling the largest raise of a concrete dam in the U.S. and the largest using roller-compacted concrete in the world. A groundbreaking ceremony on July 9 will kick off the project to raise San Vicente Dam, Lakeside, Calif., in the final phase of the San Diego County Water Authority’s Emergency Storage Project.
“It will more than double the capacity of the reservoir,” says Kelly Rodgers, authority project manager. “San Diego relies primarily on imported water.” Water supplies from the Colorado River and from northern California could be disrupted by an earthquake, so increasing San Diego’s storage will help reduce that threat as well as threat from drought.
