What are the colored flags, paint markings and wood stakes for?
The colored flags and paint markings represent locations of underground utilities. Each color corresponds to a different type of utility. The most common are blue (water lines), green (sewer lines), yellow (gas lines), orange (telephone or fiber-optic lines) and red (electrical lines). The City of Des Plaines uses pink to mark out project specific information, such as removal limits. Wood staking is placed for reference points on the project. These indicate project stations, elevations or locations of various proposed features. Please do not remove any flags or staking, as these are critical markers used for constructing the project. For more information about locating underground utilities, see this web page.
