DTE Line Clearing

Detroit Edison contracts all line clearance work to professional tree-trimming services. The crews follow generally accepted industry standards for line clearance, including directional pruning.

Directional pruning is recommended over topping, rounding or other pruning practices. Directionally pruned trees:
- Are less susceptible to insect and disease problems.
- Have a stronger overall structure of the tree that is more resistant to high winds and heavy ice.
- Have only those branches that pose a threat to power lines removed.
- Have future growth directed away from power lines.

Some trees, such as evergreens with one main trunk growing straight up into the power lines, must be topped to allow safe clearance for high-voltage power lines.
