Document Description
The project would include installation of an alternate underground power line and modifications and/or removal of the existing overhead electrical power transmission lines from the Agency's Wohler substation to the Agency's pumphouses and generators at the Mirabel facility. The underground electrical power lines would consist of concrete encased nonmetallic 12 kV conduits approximately 8,000 feet long. The underground power lines will run southward from the substation at the Wohler Facility within an existing service road located along the east bank of the Russian River. The 12 kV line will then cross the river as an overhead segment, approximately 120 feet upstream north of the inflatable dam at the Agency's River Diversion Structure (RDS). At the western bank of the Russian River, the power line would extend southward from the RDS facility along an existing levee road to the Agency's pumphouses at the Mirabel facility. The underground electrical power lines would be located within an existing service road located along the western bank of the Russian River.
