Title

Copper Basin Discharge Valve Replacement and Access Road Improvements Project

Description

The proposed Project would rehabilitate the slide gate valve and replace the discharge valve within the Copper Basin Dam valve house; install new conduit and electrical components within the valve house; install three new concrete pads and electrical components 250 feet southwest of the Copper Basin Dam; install and anchor-in-place approximately 250 feet of above-ground electrical conduit from the new concrete pads to Copper Basin Dam; replace the ladder on the dam face; install a new catwalk and stairs immediately downstream of and adjacent to the valve house; remove and reconstruct two existing concrete weirs approximately 125 feet downstream of Copper Basin Dam; and install electrical conduit and instrumentation from the two weirs along the catwalk to the valve house. The proposed Project would improve approximately 1.66 miles of the existing dirt access road around the perimeter of Copper Basin Reservoir to facilitate safe access to the base of Copper Basin Dam. Improvements to this existing dirt access road include re-grading the road; paving steep segments of road and installing metal beam guard railing for safety; constructing Arizona crossings at drainage crossing locations; installing v-ditches and riprap outlet structures along the access road to control runoff; and installing vehicle turn out areas and safety signs.
