Southern California Edison (SCE) has resumed work in the TRTP right-of-way. SCE has hired multiple contractors to start the underground construction in multiple locations in order to keep the project on time to meet deadlines to deliver renewable energy. It is anticipated that work will continue through late 2016 / early 2017.
SCE Undergrounding Update Presentation:
For a general overview of the undergrounding plans for the Southern California Edison (SCE) Tehachapi Renewable Transmission Project (TRTP), review the SCE update which was presented at the Tuesday, September 23, 2014 City Council meeting by clicking on the links below:

SCE contractors will deliver vaults on the following schedule: Monday March 9th south of Prairieview Circle (west of Lost Trail Drive) and south of Eucalyptus Avenue (east of Canon Lane); Wednesday, March 11th east of Calle Madrid (south of Paseo Tortuga). A vault consists of eight sections of concrete block which are each about 10 ft. tall and 10 ft. wide. Each individual section will be transported separately on a 40-foot flatbed truck. Parking will be restricted to ensure safety during the deliveries.
Additional Horizontal Directional Drilling Rig to be Installed in Early March
SCE's TRTP team has decided to add a second horizontal directional drilling rig to drill east to west under the flood control channel and the big hill on Peyton Drive. The location is south of Garden Court, north of Alder Place, and west of Cork Drive. Sound walls will be erected adjacent to homes to reduce the impact. SCE has delivered a letter to notify residents in the adjacent neighborhood. See additional information below about horizontal directional drilling.
March 9 - 15, 2015
Construction activities as part of Southern California Edison’s (SCE’s) Tehachapi Renewable Transmission Project (TRTP) will include the following:
*Please Note: Schedule is tentative and may change depending on weather and other factors.
A water truck will be on the utility right-of-way to help control fugitive dust. If at any time you have concerns, please call SCE at (877) 795-8787. While dust is a part of construction and cannot be completely eliminated, SCE implements measures to minimize impact and to ensure compliance with dust level requirements. A water truck will be used in the utility right-of-way to minimize such dust.
Horizontal Directional Drilling
Horizontal Directional Drilling (HDD) is a method of installing underground utilities when trenching work is impractical to perform. The 500 kV underground project in Chino Hills will require two HDD sites along the route. Southern California has developed an informational brochure that provides additional information. HDD construction activity is anticipated to begin in November of 2014 and continue through the end of 2015.
Construction hours are:
Chino Hills locations: 7:00 a.m. - 7:00 p.m., Monday – Friday; 8:00 a.m. – 6:00 p.m., Saturday
Chino locations: 7:00 a.m. – 8:00 p.m., Monday – Saturday
Tips for Minimizing Construction Impacts
SCE is committed to minimizing any inconvenience and ensuring the safety of both the public and project personnel during this work. In addition to SCE and contractor efforts to minimize the impacts to residents and businesses during construction, here are some simple tips that may help you reduce construction disturbance:
