Changes to drinking water quality regulations require open air reservoirs to be covered, bypassed, or removed from service. To comply with these regulations, the LADWP will be installing a floating cover on Upper Stone Canyon Reservoir, which is located in the Beverly Glen area and currently services the adjacent communities and the UCLA campus. LADWP will temporarily remove Upper Stone Canyon Reservoir from service in order to install the cover. Before this can be done, the LADWP must install a new water pipeline to provide continued water deliver to the surrounding communities while the reservoir is temporarily removed from service.

Project Description

LADWP will install approximately 385 feet of 36‐inch diameter water pipeline at Sunset Boulevard and Hilgard Avenue. The large diameter pipeline, known as the Charing Cross and Hilgard Bypass Line, will connect to existing infrastructure at the intersections of Sunset Boulevard and Hilgard Avenue and along Hilgard Avenue south of Charing Cross Road. The new pipeline will ensure continued water deliver to the surrounding communities while the reservoir is out of service, and will also provide improved redundancy in the system necessary for future maintenance and in case of emergency.

Construction will require traffic modifications along Sunset Boulevard and Hilgard Avenue from mid-June 2015 to January 2016. LADWP has coordinated this work with UCLA y Metro in order to complete the construction along Sunset Boulevard before fall classes at UCLA resume in an effort to reduce the traffic impacts to the area. Refer to the dates and maps under Construction Details below for additional traffic information.
