After you contact 811, participating utility companies review your request to determine whether they have underground facilities near your project area. Most requests are processed quickly and without issue. Here’s what you can expect.
Each participating utility company reviews your request individually. Only utilities that have facilities near your work area will respond.
• Some utilities will visit your property and mark underground lines with paint or small flags
• Some may respond with a “clear” message if no facilities are present
• You may not be contacted directly unless clarification is needed
Markings indicate the approximate location of underground lines. Depth is not shown.
• Some utilities may respond with a “clear” message if no facilities are present
• Only utilities with facilities near your project area will respond
• You must confirm that all required utilities have responded before digging
Utility markings are valid for a limited period and may fade over time due to weather, mowing, or normal yard activity.
• Do not dig if markings are missing or unclear
• Contact 811 if your project is delayed or markings fade
