Staff Reports

CHINO HILLS– The Tehachapi Renewable Transmission Project will deliver electricity from new wind farms in the Tehachapi area to SCE customers and the California transmission grid. Consisting of new and upgraded electric transmission lines and substations between eastern Kern County and San Bernardino County, it plays a vital role in meeting California’s renewable energy goal of 33 percent by the year 2020.

 

Construction Activities from January 25th – 31st
During the period January 25 to 31, 2016 construction activities as part of Southern California Edison’s (SCE’s) Tehachapi Renewable Transmission Project (TRTP) will include the following:

  • Surveying, dust control, vegetation, net inspection, soil and material exportation throughout the project route
  • Tower construction east of the East Transition Station at Pipeline Avenue and SR71
  • Mainline trenching which includes trenching and increased truck traffic along adjacent streets at the following locations: west of Pipeline Avenue (south of Yellowstone Circle), and south of Garden Court (east of Lobelia Drive and west of Cork Drive)
  • Vault excavation/installation work south of Eucalyptus Avenue (east and west of Canon Lane, and east of Western Hills Country Club), and west of Pipeline Avenue (south of Yellowstone Circle)
  • Horizontal directional drilling south of Prairieview Circle (west of Lost Trail Drive) and south of Garden Court (west of Cork Drive).  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.
  • Grading work south of Eucalyptus Avenue (east and west of Canon Lane), and south of Eucalyptus Avenue and North of Turquoise Circle North (west of Coral Ridge Park)
  • Concrete restoration at Canon Lane
  • Transition station construction at the Eastern Transition Station (Pipeline Avenue north of Chino Hills Pkwy.) and Western Transition Station (southwest of the western end of Eucalyptus Avenue).
  • Wire stringing activities west of the Western Transition Station in Chino Hills to Tonner Canyon in unincorporated Los Angeles County, and east of Pipeline Avenue and continuing across SR71 in Chino to just west of Central Avenue. *A small helicopter will be used to position equipment and personnel.  There will be periods when the helicopter will hover in the project area to perform these activities.
  • Cable pulling activities west of Avenida Cabrillo and just east of Calle Madrid
