3.2 Specifically Defined Geopolitical Service Area with No Overlap77/
The 811 centers serving a specifically defined geopolitical area are structured so that an excavator need only make one notification, and a facility owner/operator need only belong to a single 811 center per defined geopolitical area.
811 programs are designed to promote ease of use for members (facility owners/operators) and excavators. Although this ease of use is enhanced when an 811 center serves a specifically defined geopolitical area that does not overlap with the service area of another 811 center's service area, non-overlapping service areas are not essential. There are three requirements that an 811 program must meet to be considered as having implemented this best practice:
- The program permits an excavator to use a single point of contact to submit and follow up on a notice of intent to excavate and to notify affected facility owners/operators.
- The program permits a facility owner/operator to join a single 811 center and receive all appropriate notices.
- The program is designed to share all pertinent information among 811 centers in the event more than one exists.
