Specifications include, but are not limited to: 1. Utility lines will be indicated by markings using current APWA color codes. Markings should be 18”-24” in length and 2” in width. 2. The owner of a facility should be indicated by initials or by name in letters 6” high at the beginning and end of the locate. On long locates the facility owner should be indicated every 100’. 3. When known, the total number of lines within the ground will be indicated. The number of lines indicated should be based on the physical lines that you could place your hands on. Multiple cables twisted together to form a single facility, as in the case of electric lines, would be considered one cable for locate purposes. 4. If a facility is known to be present but the total number of lines for a facility cannot be determined a corridor marker may be used. The corridor marker should indicate the approximate width of the facility. A marking resembling the letter “H” lying on its side will indicate the corridor marker. 5. When known, the size of the line being located will be indicated. Line size will indicate the outside diameter of the pipe or structure. The oversized utility marking should indicate the approximate size of pipe or structure. A mark resembling the letter “H” lying on its side, bisected by line extending along its length will indicate the oversized utility marking. The committee discussions centered on indicating sizes of single physical structures such as gas lines, sewer lines, water lines, and storm drains.
