Tree Pruning and Planting Safety
Call or Click Before You Dig
- In many areas, power lines are buried underground.
- Before digging, planting trees, setting fence posts or excavation, call 811 (1-800-344-7233) or visit KansasOneCall.com.
- Underground power line locations will be marked at no charge, please give a two day notice.
Overhead Tree Trimming Safety
- Never get closer than 10 feet to an overhead power line.
- Only allow Westar Energy personnel to de-energize an overhead line.
- Always use personal protective equipment when tree trimming.
- Before trimming, inspect the surrounding areas to identify possible hazards.
- Mark off areas around the tree trimming to prevent bystander access.
Right Tree in the Right Place -- Responsible Planting Practices
- To keep new trees from growing into utility lines, plant small, medium and large mature-growth trees a proper distance from power lines.
- Planting around or close to underground utilities is not desirable, since the root systems may disrupt service.
- Planting shrubs or ornamentals that reach 1 foot tall at maturity should be avoided around padmount transformers.
- All plant materials with a mature height greater than 1 foot should be planted at least 10 feet from an underground line or transformer.
- These distances are necessary to provide access to the transformer for maintenance or to restore service in the event of a power outage.
