Geology and Geotechnical Services
Fault Hazard Investigation
College of the Redwoods
Eureka, California

Over the past 10 years, LACO has conducted seismic hazard, fault rupture and geotechnical investigations for the College of the Redwoods, Eureka Campus. These investigations were performed as part of the College of the Redwoods building development program. The existing structures were built before it was recognized that the campus was constructed on the surface expression of the active Little Salmon fault. Fault rupture hazard investigations were performed to assess potential building sites on this campus within an Alquist-Priolo fault hazard zone.

• LACO geologists evaluated the potential for surface ground deformation associated with fault bend folding and surface rupture.
• Approximately one mile of fault evaluation trenches were excavated, mapped and backfilled.
• Successful completion of this project has allowed the College to proceed with the development plans, including the construction of a new Learning Resource Center and Child Development Center at a total construction cost of $18.4 million.
