What does a white mark out line mean?

• A. Proposed Excavation
• B. Water
• C. Electric
• D. Temporary Survey Markings

Answer: (A)

White mark-out lines indicate proposed excavation. This color is used to show where digging is planned in the future, so crews can plan, coordinate, and protect existing utilities during the project. It’s not marking a live utility location today. Other colors mark existing services: red for electric, yellow for gas, blue for water, green for sewer, and pink for temporary survey markings. So the white line specifically points to planned digging rather than current underground lines. Always verify with the latest locate ticket and follow 811 procedures before any digging.
