Rocky Mountain Power to conduct annual vegetation maintenance on overhead powerlines

Rocky Mountain Power is conducting annual vegetation maintenance in the fire high consequence areas(FHCA) on all overhead powerlines. This work is stretched along the wildland urban interface(WUI) on the east bench of the Salt Lake Valley. Work has already started in the Avenues, City Creek Canyon, and moving into Olympus Cove.  Efforts will continue south-bound until South Mountain in Draper is reached. This work will be ongoing through the summer. All lower elevation areas (WUI) will be first priority. Then, as the weather allows for access crews will move into the higher elevation canyons.

The following canyons include; Emigration, Millcreek, Parleys, Big Cottonwood, and Little Cottonwood. All landowners with required maintenance will be notified by door card, mail, or personal contact. If questions arise, there is a minimum of 5 days for landowners to respond before you could expect tree crews to start performing the scheduled maintenance.

 This maintenance consists of 4 main objectives:

  1. Annually inspect all circuits that are located in the fire high consequence areas

  2. Mitigate trees that are of high risk for structural failure and have a high likelihood of contacting an overhead powerline if they fail

  3. Prune or remove encroaching trees to ensure vegetation does not violate minimum clearance distances prior to the next annual inspection

  4. Pole Clearing - Remove vegetation to bare ground within a 10 foot radius of subject poles. Use approved herbicide to prevent plants from growing back

*Herbicide is registered with the U.S. Environmental Protection Agency and will be applied in accordance with the label requirements and federal, state and local regulations.


Attached is two maps with an overlay of the FHCA boundaries.


This work is critical to aid in the prevention of potential fires and to protect our communities, Public lands, watershed and more.
