Bonneville Power Administration proposes to install about 500 feet of 2-inch diameter fiber optic conduit within Bonneville Power Administration’s Fidalgo-Lopez transmission line right-of-way on the east side of Decatur Island. Conduit would be placed in a trench that would extend from an existing vault located near Davis Beach to another existing vault east along Decatur Head Drive. The depth of the trench would be about 1 foot wide by 2 feet deep (dictated by the depth to the existing underground electrical cable located beneath the trench area). The trench would be dug with a backhoe. Grass and small shrubs would be removed in the trench area during excavation.
