Blackburn Consulting performed a geotechnical investigation for this pipeline project intended to increase raw water delivery capacity and reliability for agricultural customers and local water treatment plants.  The project included over 5.5 miles of 48-, and 36-inch diameter raw water pipe, parallel 8- and 12-inch diameter treated water pipeline, a new outlet control facility on the Lower Cascade Canal, a new flow control facility and encasement of a portion of the Upper Grass Valley Canal.  Our services included drilling and sampling, trenching, seismic refraction, field resistivity, and an extensive laboratory testing program. We prepared technical memos for preliminary design, a Geotechnical Design Report, a Geotechnical Data Report, and a Geotechnical Baseline Report.
