Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2015-0462-R1, pursuant to Section 1602 of the Fish and Game Code to California Department of Transportation. The project designed to acquire information on the physical properties of the rock and sediments of the Sacramento River bed channel along the north and south bound bridges of I-5. Approximately 18 bore holes will be drilled or hammered to a depth of approximately 150-200 feet using ad rill of 4 inches in diameter within a casing of 6 inches in diameter. Twelve of the 18 borings will be within the Ordinary High Water Mark (OHWM) and six will be on the banks outside the OHWM. Boring activities are planned to occur between Jan. 1, 2016 and March 31, 2016 (preferred work window) or June 1 to July 1 as a secondary backup work window. Each bore hole is expected to take two to three days to complete. Boring in the river will be performed by equipment mounted on a barge or other floating platform which will be anchored to the river bed. Boring outside the OHWM will be performed using truck mounted drilling equipment.
