What Are Those Flags?

Have you ever wondered about small plastic flags or colored letters and symbols located on the side of a street? Utility workers use these to show the location of underground lines so people can dig a safe distance away from them.

If you tamper with these flags and symbols, you put others at risk of contacting an underground line. Help protect your community by leaving them alone.
