LARGE-SCALE LANDSLIDE INVESTIGATION AND REPAIR
This project involved a large (500 feet in width by 800 feet in length) landslide that occurred in a residential neighborhood destroying some homes and threatening others.
HYDROELECTRIC PROJECTS
Following heavy rainfall, a rock topple failure occurred adjacent to a penstock in Northern California.
DAM DESIGN & WATER TANK RECOMMENDATIONS
CSA was contracted by California Water Service Company (CWSC) to investigate possibly increasing the drawdown rate at their Bear Gulch Reservoir in Woodside, California.
LANDSLIDE INVESTIGATION AND REPAIR
This was an emergency project involving the formation of a landslide on the downstream face of an earth dam at Artesa Winery in Napa Valley. Cotton, Shires and Associate’s initial response included engineering geologic mapping and assessment of the situation.
EMERGENCY ROCKSLIDE INVESTIGATION AND REPAIR
During heavy rainstorms in February of 2007, a steep hillside in a densely populated residential area of San Francisco failed as a large, catastrophic rockslide. CSA was retained to provide emergency geotechnical investigation and repair services to reduce the hazard from falling rock.
SAN ANDREAS FAULT TRENCHING
At a site in the Santa Cruz Mountains near the City of Saratoga, CSA performed a fault investigation for a proposed facility located within the Alquist-Priolo Earthquake Fault Study Zone surrounding the San Andreas fault.
