Tree Clearance: Branches Near Power Lines and Overgrowth—What to Check and What to Do Next

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Stop pruning, climbing, mowing under the canopy, and moving ladders or equipment toward the line. From a safe ground position, look for a conductor that is touching vegetation, a branch that can swing into it, a downed or sagging line, sparks, smoke, or a damaged pole; keep everyone and pets away from the area.

   Expected result: The line is down, arcing, smoking, visibly damaged, or in contact with a branch, or the line remains overhead with branches only approaching it.

   Next step: For a downed, arcing, smoking, or contacted line, clear the area without touching the tree, line, fence, vehicle, or other potentially energized object and contact the utility or emergency service according to local emergency guidance. Otherwise continue only with ground-level observations and arrange utility/tree-professional coordination.

   Stop if: Stop immediately for any line contact, arcing, smoke, crackling, a damaged pole, or a branch that has fallen onto the line.

   Why this matters

   Why: Contact, damage, or electrical activity is an immediate electrical and fire hazard. Approaching overgrowth without those signs is still line-clearance work when the branch or tool could enter the minimum approach distance.

2. Check 2

   From the ground and without a ladder, pole, tape, drone, thrown object, rope, or other tool, record whether the vegetation is on the homeowner's side, in a pole corridor, or under a high-voltage tower; note healthy growth, deadwood, broken limbs, lean, and movement in the current weather.

   Expected result: The line type or ownership is unclear, the branch distance cannot be judged without approaching, the tree is split or leaning, or growth moves toward the conductor in wind.

   Next step: Keep clear and give the utility and a line-clearance tree professional the location, photographs taken from a safe position, and the observed condition. Do not try to improve the view by climbing or handling the tree.

   Stop if: Stop the inspection if visibility would require entering the canopy, approaching the conductor, or standing beneath a suspended or broken limb.

   Why this matters

   Why: Uncertainty, tree instability, and movement can change the fall or contact path. A ground photograph and location are useful for triage, but a photograph cannot establish a safe clearance or authorize cutting.

3. Check 3

   Use the 10-foot threshold only as a safety boundary, not as a homeowner trimming allowance: if any branch, person, ladder, tool, rope, or equipment could come within 10 feet of an energized line, or if the voltage and distance are unknown, stop the work. Do not try to measure the gap with an extendable tool.

   Expected result: The vegetation is clearly well away from the line and no planned work could bring a person or tool closer, or the gap is near 10 feet, shrinking with growth, affected by wind, or impossible to confirm safely.

   Next step: If the boundary is uncertain or could be entered, do not trim or remove the vegetation; have the utility identify the line and coordinate trained line-clearance work. If it is clearly outside the hazard area, still ask the utility or qualified tree professional about mature clearance before planting or pruning toward it.

   Stop if: Stop for an uncertain voltage, uncertain distance, wind-driven movement, sag, or any need to put a body, tool, or equipment within the boundary.

   Why this matters

   Why: OSHA's 10-foot minimum applies to unqualified workers around systems at 50 kV and below, with greater distances for higher voltages; line-clearance workers use specialized training, voltage information, and approach controls. A visual gap that seems adequate today may not account for sag, sway, or future growth.

4. Check 4

   Identify the likely line owner from a safe location and contact the local utility or applicable authority about vegetation management, planned trimming, an easement or right-of-way, and whether the line is distribution or transmission. Give the location and explain that branches are overgrowing toward the line; do not assume a previous visit or property ownership transfers the work to you.

   Expected result: The utility confirms an upcoming vegetation inspection or work order, directs the concern to another line owner or local regulator, or cannot identify responsibility from the initial report.

   Next step: Record the utility's instructions and keep the area clear until the responsible party assesses it. If responsibility is disputed, provide the right-of-way or property information to the utility and the relevant local or state authority; do not cut while waiting for an answer.

   Stop if: Stop any proposed cutting when ownership, permission, line status, or the applicable right-of-way is unresolved.

   Why this matters

   Why: FERC says vegetation decisions are primarily made by the electric utility subject to state/local requirements and right-of-way terms. Transmission and distribution lines can follow different programs, so the first contact may need to route the report.

5. Check 5

   Prepare a handoff for a trained line-clearance tree professional: include the address or safe location description, ground-level photographs, line type if known, tree species or approximate size, dead or broken limbs, recent weather, and whether the utility has been contacted. Keep people out of the drop zone while waiting.

   Expected result: The professional or utility can confirm a safe work plan, de-energization or other utility coordination, approach controls, and a method that accounts for falling limbs, ropes, equipment, and future regrowth.

   Next step: Follow the utility and professional's written or verbal safety boundary and do not assist from within the work zone unless specifically trained and assigned. After work, monitor for new growth and report renewed encroachment rather than trimming it yourself.

   Stop if: Stop and postpone the work for high winds, lightning, icing, unstable trees, an uncoordinated utility, or a crew that cannot explain its line-clearance controls.

   Why this matters

   Why: A safe clearance plan requires more than a cut location. OSHA identifies hazard assessment, training, approach distances, weather limits, and specialized equipment as part of line-clearance work.
