Ever wondered what the little flags public works crews plant in your yard every spring mean? Confused by blue spray paint across the road? It means something important is lurking underground, and you can actually identify what it is if you know the ~secret code~ (it's not a secret, it's right here)

An APWA Guide to Uniform Temporary Marking of Underground Facilities. This text heavy document features lots of information for public works professionals, but it also explains what the different color of markings construction crews leave in your yard mean.
White—Route of proposed subsurface line or location of proposed excavation;
Red—Electric power lines, cables and conduit systems and lighting cables;
Yellow—Gas, oil, steam, petroleum, gaseous, or dangerous materials;
Orange—Communications, cable television, alarm or signal lines, cables or conduit systems;
Blue—Water, irrigation, and slurry lines;
Purple—reclaimed water;
Green—Sewer and drain lines.
