Where We Drill: Wake, Johnston & Franklin

Raleigh–Cary, NC HDD service area — 3 component counties, principal and satellite cities — The the Triangle's east service area — U.S. Census Bureau county boundaries; cities marked are where crews most often mobilize.

The service area is the OMB-defined Raleigh–Cary metro — Wake, Johnston, and Franklin counties, from the tech corridors of the west to the coastal-plain edge at Smithfield. County pages below carry the local picture: the corridors, the ground, and the authorities whose permits govern crossings.
