Properties with trees growing into power lines are likely to experience 'blinks' in electric service or power outages. Columbia Water & Light budgets $2 million annually to trim trees along overhead power lines. Trimming trees on a three year cycle helps the reliability of the electric system and it keeps the amount needing to be trimmed to a minimum.
Columbia Water & Light will notify property owners two to three weeks before trees are to be trimmed. You can agree to either having your tree(s) trimmed or removed. If a tree damages electric infrastructure, the tree(s) will be cut back so service can be restored.
Sign up for the Trade-A-Tree program. Columbia Water and Light will remove the hazardous tree and arrange for the planting of a more appropriate species, free of charge.
Trees near power lines in Columbia are trimmed on a three year cycle. Columbia Water & Light's policy is to trim trees for a three year growth cycle so the branches will not interfere with the lines before the next trimming cycle. The amount trimmed depends on how much a particular species grows in three years. Proper trimming practices prescribed by the National Arbor Day foundation are followed to maintain the health of the tree.
The right tree needs to be planted in the right spot. Keep in mind the dimensions of the tree when it is mature to determine the best placement.
Tree roots can also cause problems with your underground utility services, foundation, sidewalks and driveways. Most trees have root spans similar to the mature width of the tree. Plan distance away from structures accordingly.
The following trees are susceptible to broken limbs, disease and other problems in our area:
Columbia Water & Light has received the Tree Line USA award from the National Arbor Day Foundation every year since 1998. The program honors utilities for responsible tree trimming practices and programs to promote appropriate planting near utility lines. Proper planting techniques are encouraged throughout the year by Columbia Water & Light employees. The utility also provides free shade trees through its Tree Power program.
