Which color marks a proposed excavation site?

• A. Blue
• B. White
• C. Pink
• D. Green

Answer: (B)

Color-coded markings guide crews on what’s underground and what work is planned. White specifically marks an area where excavation is proposed, signaling that digging will occur there and that coordination with utilities is needed before starting. This helps prevent striking existing lines and keeps the work sequence safe. Other colors point to existing utilities—for example, blue marks potable water and green marks sewer—so White stands out as the marker for future digging.
