What is the required distance for marking the location of the underground line?

Explanation:
The distance to mark is within two feet of either side of the line. This tight tolerance gives a precise indication of where the underground facility runs, helping excavators stay clear of the line. Markings much farther away (ten, twenty, or a hundred feet) would be too imprecise and could lead to digging near or over the utility. Placing markers on both sides within two feet creates a clear, accurate corridor that guides safe excavation.
