Construction Update:
During the period of October 20 – October 26, construction activities as part of Southern California Edison’s (SCE’s) Tehachapi Renewable Transmission Project (TRTP) will include the following: 

  • surveying and staking
  • clearing of vegetation and grubbing
  • mobilization of equipment at the Western Transition Station, located south west of the western end of Eucalyptus Avenue 
  • trenching work (Avenida Cabrillo, Little Bend Drive, Calle Madrid, Maplewood Drive - there will be street lane closures at these locations)
  • installation of chain-link fencing along the edge of the utility right-of-way within the project area to ensure safety of the public and project personnel during construction (Eucalyptus Avenue to Calle Madrid and Paseo Tortuga, and Chino Hills Parkway to Maplewood)
  • implementation of Best Management Practices (BMP’s) and monitoring project site safety, project materials, and environmental compliance in accordance with the project’s Storm Water Pollution Prevention Plan
  • equipment mobilization, fence installation, wall blanket installation, wall saw cutting - Eastern Transition Station between Pipeline Avenue and State Route 71  (Note for next week - Grading and other ground breaking work will begin the week of 10/27 and will be underway from 7:00 pm to 5:00 am to reduce the impact on the Montessori School)

Project Area:
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).

Please Note: Schedule is tentative and may change depending on weather and other factors.

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. 

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

  • 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!
