Document Description
American Dark Fiber, in coordination with the California Department of Technology, proposes installation of approximately 21 feet of underground 2-inch high-density polyethylene conduit with fiber optic cable within Caltrans right-of-way (ROW) along State Route (SR) 1 in Marin County, California. Methods of conduit installation include open trenching, to be done in accordance with the traffic control plan. Steel plates would be used to maintain traffic flow on all driveways. During non-working hours, contractors would fill or cover all open pits or trenches. Work also includes placement of temporary traffic control devices and signage as well as installation of one 36” wide by 60” long by 24” deep vault. Fiber optic markers will also be installed at the vault location as well as approximately every 500 feet along the conduit path, with metallic disk markers installed in the pavement. All work is to take place within the Caltrans ROW.
