Where We Drill: the Five-County Metro

Austin–Round Rock–San Marcos, TX HDD service area — 5 component counties, principal and satellite cities — The Greater Austin service area — U.S. Census Bureau county boundaries; cities marked are where crews most often mobilize.

The service area is the OMB-defined Austin–Round Rock–San Marcos metro — Travis, Williamson, Hays, Bastrop, and Caldwell counties. The county pages below carry the ground truth: which side of the Balcones line the work falls on, where the growth is pushing, and whose permits govern the crossings.

Travis County

The core: split ground, the river through downtown, and the Barton Springs zone.

Williamson County

Round Rock to Taylor: the manufacturing corridor pulling the metro northeast.

Hays County

The I-35 south corridor: Kyle and San Marcos growth on spring-country karst.

Bastrop County

The eastern frontier: river-bend growth, pine and clay, and film-lot-to-fab-suburb change.

All component counties: Bastrop · Caldwell · Hays · Travis · Williamson.
