SBFCA - Feather River - Yuba City, CA
Drilled and sampled 50ea borings to 130ft. All borings were drilled from the levee crest using rotary wash methods through gravels, cobbles and dense sands. Continuous 5ft long punch cores were taken from 100ft -130ft. All borings were grout back-filled at the completion of exploration.
