Landscaping & Tree Trimming

Existing trees

It’s important for homeowners to ensure trees and other plants don’t grow too close to powerlines and other electrical equipment. Here’s why:

  • Tree limbs that come down during a storm or high winds can bring powerlines with them causing a power outage and leave live powerlines on the ground which is a severe safety hazard.
  • Tree branches that touch powerlines can also cause a fire and create an electric shock hazard if someone touches the tree.

If you have trees that are growing too close to powerlines, contact a trained arborist or your local electric utility to have the tree safely trimmed.

 

Planting new trees and shrubs

If you’re planting new trees on your property, make sure to plant them far enough away from the powerlines so even when your sapling is a mature tree, it doesn’t come too close. Follow ESA’s tree planting guide for suggestions on species that are appropriate to plant near powerlines.

Thinking about planting shrubs around that green box on your property? Remember, this box – called a padmount transformer – contains electrical equipment that runs underground. Never dig near one, and don’t plant shrubs or plants within 1 metre of the box. This will make it difficult for utility personnel to find and access the box if there’s a power outage.
