Let’s Keep Trees Away from Power Lines
Trim Trees for Safety
Where to Plant
Taller trees should be planted far away from overhead power lines. Remember, trees grow outward as well as up. For trees that will grow taller than 25 feet in height, choose locations that offer plentiful space – at least 20 feet away from power poles or overhead lines when the tree is fully grown.

Pruning Trees is a Job for Experts
If your trees have grown into or near power lines, pruning requires the expertise of a qualified line-clearance arborist. To report trees growing into or near power lines, call us at 1-800-655-4555 or submit a Tree Trimming Request online.
Remove Dead, Dying, and Diseased Trees
Trees and shrubs can cause safety hazards and power outages if they fall on power lines. Trees that are dead, dying, or diseased pose a serious risk, and we are committed to removing those that threaten our electricity system. To arrange an inspection of trees on your property, call us at 1-800-640-3652 Monday - Friday 8 am - 5 pm.
Never Let Kids Play in Trees Touching Power Lines
Remind children to stay far away from trees that are growing into – or near – power lines. They could be energized and dangerous. More safety tips:
- Build tree houses, tree forts, and tree swings far away from power lines
- If a kite or balloon gets stuck in a tree near power lines, don’t attempt to retrieve it; instead, call us at 1-800-611-1911
- Never leave ladders against trees that are growing into or near power lines

Our Ongoing Efforts Related to Bark Beetle Crisis
We are working with federal, state, and local agencies to remove dead, dying and diseased trees that were weakened by an insect called the bark beetle -- and by years of drought.
This situation poses a potential hazard to people and property in affected communities, as well as to our electricity facilities.
The California Public Utilities Commission directed us and other affected utilities, in 2003, to take all reasonable and necessary actions to remove dead or dying trees threatening power lines in San Bernardino, Riverside, San Diego and L.A. County. In L.A. County, the emergency situation was later found to no longer exist and a proclamation was issued in 2011 rescinding the emergency there.
