Which color line marks a temporary survey marking?

• A. Red
• B. White
• C. Pink
• D. Purple

Answer: (C)

Color coding for field markings shows what’s underground and why it’s marked. Pink marks are used for temporary survey markings, placed by survey crews to outline control points or reference lines during a project. They’re meant to be short-lived and removed after the surveying work is finished, which is why they’re distinct from permanent utility markings. In contrast, other colors map to specific utilities or planning actions—red for electric power lines, white for proposed excavation limits or construction boundaries, and so on—so using pink helps clearly signal that this marking is only for temporary survey work.
