Question of the Week: LowerManhattan.info

Q: What does the neon writing on streets and sidewalks signify?

A: The writing on the pavement is part of the Uniform Color Code. Before any digging commences on a project, workers mark the street with color-coded cues to ensure that buried utility lines are not accidentally cut. Here's a guide to what's buried beneath those scribbles:

White - Proposed Excavation
Pink - Temporary Survey Markings
Red - Electric; power lines, cables, conduit & lighting cables
Yellow - Gas; oil, steam, petroleum & gaseous material
Orange - Communications; alarm, signal lines, cables or conduit
Blue - Potable Water
Purple - Slurry Lines; reclaimed water, irrigation
Green - Sewers & drain lines
