Springs, faults and the recharge zone
San Marcos Springs flow from the Edwards Aquifer where the Balcones faults bring it to the surface. Parts of Hays County to the west and northwest lie over the aquifer鈥檚 recharge zone, where the TCEQ鈥檚 stricter septic rules apply: planning by a professional engineer or professional sanitarian, generally at least an acre per home, and set-backs from caves and sinkholes. For Hays County lots, the older-plat exception date in that rule is June 21, 1984.
