No lighting is require and the pump and generator are very quiet.)

This work will take place within the existing utility right-of-way corridor in the cities of Chino and Chino Hills between the west end of Eucalyptus Avenue and the Chino Valley Freeway (71).

Eastern Transition Station

Demolition work at the eastern transition station, located between Pipeline Avenue and the Chino Valley Fwy (71) is underway. There will be periods of night work at this location in order to reduce construction noise impacts to the Montessori School of Chino Hills.

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 give us a call.

Tips for Minimizing Construction Impacts

SCE is committed to minimizing any inconvenience and ensuring public safety during this work. In addition to SCE efforts to minimize the impacts to residents and businesses during construction, here are some simple tips that may help you reduce construction disturbance:

  • Close all windows and doors facing the construction area in order to reduce noise and dust
  • Watch for information updates in the form of mailers, door hangers, etc. to ensure you have the most up-to-date information about construction activities taking place in your area.
  • Cover items such as vehicles and swimming pools

Construction hours are:

Chino Hills locations: 7 a.m. - 7 p.m., Monday – Friday; 8 a.m. – 6 p.m., Saturday

Tips for Minimizing Construction Impacts

SCE understands that construction may be disruptive to daily activities of residents and area businesses. While dust during construction cannot be completely eliminated, SCE and its contractors are taking steps to minimize potential impacts to residents and businesses. To help minimize dust or noise from these project activities, residents may choose to close windows or doors facing the construction area and cover items such as vehicles and swimming pools.

Thank you for your understanding and cooperation as our project personnel work as safely and quickly as possible to complete these important electric system upgrades.
