IID’s power line clearance team ensures electric service reliability by reducing the frequency of tree-related power interruptions through practical vegetation-to-conductor clearance.
IID prunes to keep vegetation at least 10 feet clear from power lines. Higher voltage power lines require larger clearance distances. Normally, there is no charge for this service.
Manageable trees that are relatively close to power lines may be reshaped and trimmed to grow away from them. The illustrations show examples of “notch pruning,” where branches are pruned to form a notch in the upper tree crown to allow space for power lines.
Directional pruning (vertical side cut)
Horizontal internal cut
Service drop pruning
IID maintains a two (2) foot radial space around residential service drop conductors clear of vegetation.
Street light conductors and communication line
IID maintains a two foot radial space around IID owned street light conductors, communication lines and agency owed street light conductors that are under an IID maintenance contract.
Safety clearance maintenance around equipment and conductors owned by others is the responsibility of the owner.
Unmanageable vegetation, also referred to as a “cycle buster,” is defined as any fast-growing vegetation with a growth rate of 10 feet or more per year. Any unmanageable vegetation encroaching IID’s power lines will be removed. There is no charge for this service.
Hazardous trees, palm trees or other vegetation
Palm trees have only one growth tip or stalk and sometimes grow very rapidly—especially when watered frequently in hot climates such as ours. Trees, palms or other vegetation that could potentially grow 15 feet or taller located in the power line corridor will be pruned or removed as required.
Before you dig
Before you start any landscaping project, call the Underground Service Alert, toll free, at 8-1-1 two working days before you begin your project. Experts will locate electric, gas, telephone, water and sewer lines on your land.
