Electric service for you home and community is important. So are your trees. When we trim trees growing too near or into power lines, we prioritize both. FPUA uses qualified professional tree trimming contractors to manage the vegetation around our electrical facilities. To accomplish this, we use two types of pruning:

  • Lateral Pruning: removal of tree limbs at natural detachment points to help facilitate healing around the pruning site.
  • Directional Pruning: the deliberate attempt to remove those limbs growing towards the conductors and to train the tree to grow away from electrical facilities.

Cutting limbs to proper laterals helps minimize re-sprouting, which reduces the amount of re-growth into electrical facilities. Pruning to a proper lateral does not harm the tree's natural defense systems. Instead, this helps protect the tree from decay.

Note: is not our primary intent to trim the whole tree or to trim for aesthetic purposes.

Importance of Routine Pruning

A tree that is not maintained on a routine cycle will assume its normal form, which may put it in danger of coming into contact with electrical infrastructure, resulting in the need to extensively prune or remove the tree.

Minimize the Number of Cuts

FPUA's tree trimming crews work to minimize the number of pruning cuts to a tree in order to prevent serious injury to the tree. The intent with quality vegetation management is to remove whole branches that are growing toward utility facilities. When clearance distances are specified (for example, 10 feet) the cut should be made at the next suitable lateral of parent limb beyond the specified distance.

Directional Pruning

Directional pruning (also known as natural pruning) is most effective when tree characteristics such as size, shape and expected growth rate are taken into consideration. Proper directional pruning of trees growing directly beneath facilities or beside them helps direct future tree growth away from the facilities.

Removal of overhanging vegetation may or may not be necessary, depending on the type of utility facility, tree species and other factors. Overhang is never acceptable over high-priority facilities such as high-voltage electric transmission lines.

Palm Pruning

Many palm species grow large enough to affect utility facilities. Their large fronds sway in the wind and may break free, causing damage to equipment. Palms cannot be reduced in height or directionally pruned like other trees. The best solution for palms interfering with utility facilities is removal or relocation.
