Thin soil over limestone
Canyon Lake and the Hill Country above the escarpment

The escarpment line
New Braunfels, San Marcos and the Schertz area along I-35
The Balcones faults run right through here. Springs, the Edwards Aquifer recharge zone and stricter septic rules sit along this line.

Blackland clay
Marion, Geronimo, New Berlin and Seguin below the escarpment
