Large Tree Over Power Lines
in Columbia, MO
Columbia has a lot of older neighborhoods where trees planted 40 or 50 years ago have grown straight up into the overhead power lines. Areas like the East Campus neighborhood and parts of north Columbia near Broadway see this constantly. Leaving branches in contact with live lines is a fire risk, and when ice storms hit in winter, those branches can snap and take the line down with them.
Quick Answer
When a tree grows into power lines in Columbia, branches can arc electricity, start fires, or knock out power to your block during a storm. The utility company handles the lines, but the tree on your property is your responsibility. In most cases the tree needs to be removed or heavily pruned back from the conductors. Call (573) 615-8401 before you touch anything near those lines yourself.
Telltale Signs
Warning Signs to Watch For
- Branches are visibly resting on or wrapped around the power line
- You can see burn marks or blackened bark where branches touch the wire
- The power line sags more than usual between poles near the tree
- You hear buzzing or crackling near the tree on humid days
- Flickering lights inside your house that get worse during wind
Root Causes
What Causes Large Tree Over Power Lines?
Decades of Unchecked Growth
Trees planted in Columbia neighborhoods in the 1970s and 1980s were often placed without much thought about mature height. After 30 or 40 years of growth, branches reach the height of standard residential power lines, which typically run at about 20 feet.
The Fix
Crown Reduction or Full Removal
If the tree can be cut back far enough to clear the lines and still survive, a crown reduction buys time. If the trunk is already between the lines, full removal is usually the only safe option.
Ice and Snow Loading
Central Missouri gets ice storms that coat branches in a quarter to half inch of ice. That weight bends branches down into lines or snaps them off entirely, and a falling branch can pull a service line off your house.
The Fix
Pre-Storm Tree Removal
Removing the tree before winter prevents the ice-loading problem entirely. Trying to deal with it after a storm while lines are energized is not safe.

| Lights flicker or power dips during ice storms or heavy snow | ||
| Burn marks on bark near the line contact point | ||
| A branch already broke and is hanging on the line |
