The City of Los Angeles Department of Water and Power (LADWP) proposes to upgrade an approximately 1.8-mile portion of the existing Toluca–Hollywood 230 kilovolt (kV) Transmission Line 1 (TOL–HWD L1) cable, which runs underground within a pipe from the Nichols Canyon Terminal Tower to the Hollywood Receiving Station. All work would be located within the road right-of-way (ROW), the confines of LADWP property, or within an easement. The proposed TOL-HWD L1 Upgrade Project (proposed project) would include trenching and installing a new underground cable adjacent to the existing underground TOL-HWD L1 alignment from Hollywood Boulevard southeast to the Hollywood Receiving Station. The project also would include trenching and removing the existing underground TOL-HWD L1 pipe and cable and installing a new underground pipe and cable inside the same trench alignment within Nichols Canyon Road, north of Hollywood Boulevard to the Nichols Canyon Terminal Tower. Additionally, an existing transmission tower along the existing TOL-HWD L1 would be raised, and a portion of an existing Burbank Water and Power (BWP) distribution line that crosses under the TOL-HWD L1 would be lowered. To accommodate the system upgrade, modifications to the Nichols Canyon Terminal Tower and the Hollywood Receiving Station are proposed.
