Call before digging
811 and Kentucky 811 direct homeowners to request utility marking before digging. In Kentucky, the homeowner guidance says to contact 811 two full working days or more before excavation depending on project size and scope.
QUICK ANSWER
What to know first
Homeowners should contact Kentucky 811 before tree or shrub planting that requires digging. Utility marks help shape the planting layout, but they do not automatically mean every private line or overhead issue is resolved.
Kentucky 811 should be contacted before digging for landscaping projects.
Private lines may need separate locating.
Overhead lines, transformers, easements, and equipment access matter too.
GUIDE
What affects the project
Marks affect layout
Underground electric, gas, water, sewer, fiber, internet, cable, irrigation, drainage, and private lines can all affect tree spacing and whether a straight row is practical.
Utilities are above ground too
Overhead power lines, pad-mounted transformers, utility easements, and equipment access can matter as much as shovel digging.

Utility issues to review
| Utility issue | Why it matters |
|---|---|
| Underground electric, gas, water, sewer, fiber, internet, and cable | Marked lines can change planting locations and row spacing. |
| Irrigation and drainage lines | Private systems may not be marked by 811 member utilities. |
| Overhead power lines | Tree mature height must stay compatible with utility clearance. |
| Pad-mounted transformers | Access clearance must remain open for service. |
| Utility easements | Future maintenance access can limit where trees belong. |
ESTIMATE PREP
Utility mistakes to avoid
- Planting directly above marked lines.
- Blocking transformer access.
- Planting trees that will grow into overhead lines.
- Assuming old properties have accurate utility knowledge.
- Scheduling planting before utility marks are complete.

FAQ
Common Questions
Does 811 mark every line on my property?
No. Kentucky 811 can involve member utilities, but private lines such as irrigation, drainage, lighting, or private utility runs may need separate locating.
How far from a pad-mounted transformer should plants be?
Use the local utility's current clearance guidance. LG&E/KU guidance is part of the source notes for this page and should be checked before final layout.
