Extended Construction Working Hours
August 31st - September 2, 2016

Crews will be working at the Western (southwest of western end of Eucalyptus Ave) and Eastern (Pipeline Avenue north of Chino Hills Pkwy) Transition Stations until 9:00 p.m.  
 
Reason for Extended Hours: Measurement for 500kV Underground Power Cable System (cable testing).  It is a critical activity which once initiated requires we continue to completion.

Lighting Plan:
Contractor plans to use portable work lights and flashlights at the identified construction location during commissioning test activity. The lighting source model will be a self–righting work light with reflector shields for directed illumination away from sensitive receptors.  In addition, a station light will be used.

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:

  • Close windows and doors facing the construction area in order to reduce noise and dust
  • Watch for project information updates to ensure you have the most up-to-date information about construction activities taking place in your area.

Stay Informed and Encourage your neighbors to sign up to receive updates, too!
