Document Description
PCWA acquired an 8.2-acre site for the construction and operation of a second backup pump station for the Auburn Ravine Tunnel. The proposed project, as described in the original IS/MND (Jones & Stokes 2003), involved acquiring the property; constructing the pump station, access road, and associated facilities; implementing standard BMPs to minimize environmental impacts; and implementing mitigation measures prior to and during pump station construction and operation to protect environmental resources associated with the project site. The new project component that is being addressed in this Subsequent IS/MND is a new outfall system between the pump station (currently under construction) and Auburn Ravine. The new outfall system would provide a safe emergency overflow for the pump station transfer basin. The proposed outfall would consist of multiple components, including a 69-inch drain from the pump station wet well to a concrete flow control structure adjacent to the pump station; a length of open channel; two 48-inch corrugated metal pipe culverts under the wastewater treatment plant access road; and an 11-foot-wide by up to 4-foot-deep rock-lined ditch to Auburn Ravine. A portion of the outfall would be within the floodplain and would include approximately 50 feet of the dual 48-inch corrugated metal pipe culverts, a 6-foot-tall by 20-foot-wide concrete headwall, and approximately 80 feet of the rock-lined ditch.
