South Bay Aqueduct (SBA) Geotechnical Exploration
NOE - Notice of Exemption
Project involves the installation of four inclinometers. The geologic exploration will consist of four vertical borings with a truck-mounted CME 750 or similar drilling rig. Each boring will be approx. 8" in diameter and extend to a depth of 40 feet below existing grades. Cuttings will be spread on the ground adjacent to each drill hole. Where drill cuttings have the potential to erode, bio-degradable fiber rolls will be used. New access roads will be mowed prior to grading, and will be inspected by a biological monitor. Existing access roads and new access roads will be graded to allow the drill rig access.
