Establishing Power: Line Construction and Vegetation

When establishing electrical service, vegetation surrounding the power lines needs to be considered. Our goal is to provide safe and reliable power, free of vegetation conflicts. This is done by designing a safe route for the line that can be maintained for compliance with state and federal laws through out its lifetime.

PG&E representatives are willing to meet with you to discuss a route acceptable to both parties. However, it is the applicant’s responsibility to provide a route that is free of tree conflicts. A Vegetation Management representative will inspect and verify vegetation clearance requirements have been met before the power lines are constructed and energized.

Once a line is energized, PG&E continues to perform annual inspection and line clearance tree trimming in order to maintain safe and reliable power. This service is free of charge to the customer.

Clearance requirements to consider when selecting a service route:

  • All trees located directly underneath and 15 feet on either side of the pole center line should be removed. With the exception of low growing trees and shrubs that will not encroach within 10 feet of the energized conductors at maturity.
  • All hazardous trees, which are outside the 15 feet from centerline but could potentially damage our facilities, need to be removed.
  • Flammable vegetation and material located wholly or partially within 10 foot radial clearance of specified poles should be treated as follows
    • At ground level- remove all flammable material.
    • From 0-8 feet above ground- remove all limbs and foliage of living trees.
    • From 8 feet to the high voltage lines- remove any dead, diseased or dying limbs and foliage from living trees and any dead diseased or dying trees in their entirety.
