Public Safety
- To prevent injury to people climbing or working in trees adjacent to power lines.
Fire Safety

IT'S THE LAW
State law requires utility companies to maintain specific clearances (depending on voltage running through the line) between electric power lines and all vegetation.

Homeowner Liability
Failure to allow a utility company to comply with the law can result in liability to the homeowner for damages or injuries resulting from a vegetation hazard.
Many insurance companies do not cover these types of damages if the policy owner has refused to allow the hazard to be eliminated.
HOMEOWNER PREVENTION
You can help prevent electric outages, fire and public safety hazards.
- Clearing all flammable vegetation a minimum of 30 feet around your home and other structures provides the greatest chance for survival and is also required by law. (section 4291)
- Plant the right tree in the right place. If you must plant trees near power lines, make sure the maximum mature tree height is ten feet away from the closest power line.
- Plant fire resistant plants.
- Never allow children to climb trees growing near power lines.
- Never prune trees near electric lines. Call your local electric utility company first to inspect the trees. In many instances the utility may perform the tree work at no cost to the homeowner.
- Inspect the trees on your property annually for hazards. For expert advice on tree health or hazards consult an International Society of Arboriculture Certified Arborist.
