After many delays, the final stage of Southern California Edison’s Topanga Utility Underground Project is scheduled to begin on September 10 and set to be completed in approximately two months. Some of the work will happen during the daytime but most will be done at night. These dates and times are subject to change due to unforeseen operational factors or inclement weather. Work hours will vary based on permit conditions.

Improvements will only affect those in and around the downtown area.

Southern California Edison (SCE) will be replacing several old distribution poles, and removing a number of poles and sections of overhead electrical wires and equipment in the downtown area. The overhead poles and wires are being replaced with underground facilities. SCE will also be replacing two existing streetlights that are located at the intersection of Topanga Canyon Boulevard and Old Topanga Canyon Road, with new streetlights.

Project Area

This work will take place on Topanga Canyon Boulevard and on Old Topanga Canyon Road, including the intersections of Old Topanga Canyon Road and Cuesta Cala Road. Traffic will be impacted within the boundaries identified on the project map. Message boards will be posted in advance of the work zone. Intermittent lane closures will be in place during work hours. 

What to Expect

There will be trenching at the intersection of Cuesta Cala Road. SCE will be accessing underground vaults to install wiring. Services will be reconnected to the new, underground electrical system. To ensure your safety during construction, there will be intermittent traffic lane and sidewalk closures. Crew members will use appropriate traffic control signs and flags. For crews to work safely, SCE will schedule power outages during construction. In these cases, we will notify you by phone, text, email and mail at least 72 hours prior to the outages. Only a small area of Topanga will be affected by the outages and those residents/businesses will be notified accordingly.

You can sign up to receive outage alerts through your preferred method of communication via or :1-800-655-4555. ,
