Document Description
The Sonoma County Water Agency seeks to assess relocating a section of the Santa Rosa Aqueduct that crosses under the Santa Rosa Creek, which could be at risk of failure during an earthquake due to liquefaction and lateral spread. To assess the aqueduct’s vulnerability to seismic events, a geotechnical investigation is needed. This will help determine how the aqueduct may be affected by seismic activity and inform the design and relocation of the pipeline to ensure its safety, reliability, and resilience. The beneficiaries of the geotechnical investigation include the Sonoma County Water Agency, which gains crucial data to inform safe and reliable pipeline relocation and design; local communities, who benefit from improved water system safety and reliability; and engineers and designers, who receive detailed geotechnical data to guide accurate and safe designs.
