Document Description
The Project proposes to construct a regulating basin, a concrete flow control structure for Lateral Q, and a basin inlet pipe from Lateral Qc connected to a combined gravity and pumped concrete outlet structure and connection box. Project construction components are described in detail below:
• The proposed regulating basin would be approximately 18.8 acres with an operational volume of 52-acre feet. The basin would either be lined with high density polyethylene (HDPE) or clay. There would also be a three (3)-foot canal liner raise for Lateral Q upstream of the proposed basin for +/- 1,100 linear feet to the existing check structure.
• The Lateral Q concrete outlet flow control structure would be capable of passing 150 cubic feet per second (CFS) maximum. It would include three (3) Rubicon SMB 1050-3000-C Slip Meters.
• The Lateral Qc combined gravity and pumped concrete outlet structure and connection box would be capable of passing 25 CFS. It would consist of an approximately 42-inch Rubber-Gasketed Reinforced Concrete Pipe (RGRCP), one (1) Rubicon SMB 1050-2400-C Slip Meter, and would include pump, 24-inch PVC pipe, and miscellaneous fittings, meters, appurtenances, etc.
All excavation material would be balanced on-site. No spoils would be exported from the Project site. In order to power the pump, gate actuators and control systems for the SCADA, a new power connection would be required. The nearest power line follows the east side of Murphy Road, and a potential drop is near the existing control box just north of Ripon Fire Station 52.
