Different utilities use colored markings and flags indicating where their cables and pipes are buried. As required by law and prior to any digging that is to occur near these lines, the utilities must be called out to paint markings or flags showing these locations, sometimes even up to the home's connection point. Utility companies have legal easements automatically giving them the right to be on private property. There may be as many as 15 different crews out in numerous sections of the community on any given day. The City is, therefore, unable to provide each resident with notice before the crews start work.
