Document Description
DGS is proposing to upgrade the Soda Ridge California Highway Patrol (CHP) telecommunications facility to meet the CHP's Enhanced Radio System requirements. The project site is located on private land approximately 1.5 miles east of the City of Dunsmuir in southern Siskiyou County. As shown in Figure 1, the study area is located in Township 39 North, Range 3 West, Section 18, at an elevation of approximately 4,600 feet (U.S Geological Survey's Girard Ridge 7.5-minutes quadrangle). An aerial photograph of the project site and vicinity is provided in Figure 2. The proposed project site is within an existing telecommunication facility site, and is accessible via an existing unpaved road. Existing state vacilities at the site include a 20-foot-tall microwave tower, a 60-foot-tall VHF tower, a generator vault, and an equipment vault. The facilities are located on a 2,500-square-foot ground lease from Roseburg Resources. Adjoining facilities include a vacant equipment vault and tower owned by Northland Cable, and an occupied vault and 110-foot-tall tower owned by Verizon Wireless. The project would include the construction of a new 120-foot tower and a generator/equipment vault, as well as relocation of a propane tank and pad. The foundation for the new tower would consist of a 45' x 45' x 2' concrete slab, constructed 1 to 3 feet below grade and over-covered with soil. Four piers would protrude above-ground and provide support for the tower. The tower would be assembled in 20-foot sections. Ice shields would be provided to protect the dishes and structures below. The generator/equipment vault would have the same uses/capacity as the current facilities. The existing structures would be removed after the new facility is put into operation. Some trenching to house conduit would occur between existing buildings (Figure 3). The conduits would contain direct-current power, fuel, and telphone lines. All conduits would be buried a minimum of two feet deep.
