SAFELY PLANT AND TRIM TREES NEAR POWER LINES


Trees are good conductors of electricity. When they grow too close or fall into power lines, trees can cause public safety risks such as electrocution, fire and power outages. To deliver safe, reliable electricity service, it is necessary for Hydro to trim and control the growth of trees that have grown too close to power lines.

The best way for you to ensure your safety and your community’s is to carefully plan your landscaping. Remember, it is crucial to consider the height and shape of the mature tree so that you won’t have a problem once it has grown.

If you plant your tree too close to power lines, it may have to be trimmed or removed later.

Keep the following distances in mind when planting trees:



Low Zone: The low zone is the area directly under the power line and extends to 4.5 metres (15 feet) on either side. Trees and shrubs planted in this area should have a maximum mature height of 4.5 metres (15 feet) or less.

Medium Zone: The medium zone extends from the edge of the low zone to a distance of 7.6 metres (25 feet) on either side of the power line. The maximum mature height of trees planted in this zone should be 7.6 metres (25 feet).

Tall Zone: The tall zone is the area more than 7.6 metres (25 feet) from the power lines. Virtually any strong, healthy tree may be planted in this zone.
