A practical guide to public one-call marking, privately owned utilities, and why a complete excavation plan may need both.
The ownership boundary
Virginia 811 is the notification center for damage prevention. A ticket alerts participating member utilities, and those operators mark the approximate location of the facilities they own in the requested area.
The ownership boundary matters. Infrastructure on private property may belong to the owner rather than an 811 member utility, so it may not be included in the public response.

| Project condition | Investigation | Usable record | Decision supported |
|---|---|---|---|
| Participating public utility | Submit the required 811 ticket and allow member utilities to respond. | Approximate surface markings or a clear response from participating operators. | Meet the public-notification step before excavation. |
| Privately owned line | Scope a private utility investigation around the planned work. | Field designation and project-specific documentation as defined in scope. | Understand private infrastructure that the public response may not cover. |
| Complex or congested site | Use both processes and reconcile the available records and field evidence. | A clearer combined picture with confidence and limitations stated. | Identify conflicts and verification needs before work proceeds. |
Common private infrastructure
Examples can include electric or water service beyond a meter, irrigation, communications between buildings, electric to sheds or detached structures, propane systems, pet fencing, and septic components. Ownership varies, so records and the project context still need review.
Plan both steps
Create the required 811 ticket before excavation and follow the instructions for the project jurisdiction. In Virginia, homeowners and excavators can use Virginia811.com; projects in Washington, DC use Miss Utility.
When private infrastructure may cross the work area, define the project footprint and engage a private locator. The result should add useful evidence without implying that uncertainty has disappeared.
FAQ
The right answer is usually complementary coverage, not a choice between public notification and private investigation.
Virginia 811 notifies participating member utilities, whose operators mark the approximate location of their underground facilities. Lines owned by the property owner—often including services beyond a meter, irrigation, electric to an outbuilding, pet fencing, propane, or septic components—may require a separate private utility investigation.
Yes. Private locating complements the public one-call process; it does not replace the required 811 notification before excavation. Follow the rules and timing that apply at the project location, then use private locating when the work area includes privately owned infrastructure or needs project-specific documentation.
No. Public marks identify approximate facility locations, and private investigation also has limits. SafeLine interprets available evidence and classifies confidence rather than promising exact location, guaranteed depth, or complete detection where site conditions do not support those claims.
Share the project address, planned disturbance, area of concern, access constraints, and any available plans or records. A defined scope helps determine appropriate field methods and the useful output, whether that is field designation, a utility map, spatial data, or verification recommendations.
