The person that will actually be digging must be the one to call UNCC and request locates. If you have hired a contractor, it is their responsibility to issue the request. Please read the section on utility line damages carefully. Avoid hitting lines at all cost but if you do, the proper procedures are on the damaging a utility line page. Many damages and injuries result from running stakes into service lines. If you are only using stakes you still need to call for locates so that you are aware of where the utility lines enter your home. You must place your locate request at least three business days prior to digging. Utility owners will respond and mark their lines within two business days not including the day of the actual notice. There is no charge to have utility location done. It is a free service.
