Northern Bexar County sits over the Edwards Aquifer Recharge Zone. Development there faces TCEQ Edwards Rules, impervious cover caps, and Bexar County Public Works review beyond ordinary subdivision platting under Local Government Code 232.
Hill Country areas of northern Bexar County overlie the Edwards Aquifer, the region's drinking water source. Texas Commission on Environmental Quality Edwards Rules under 30 TAC 213 require water pollution abatement plans for new development on the Recharge or Contributing Zone, with stormwater best management practices, geologic assessments, and post-construction water quality controls. Bexar County Public Works coordinates plat review and infrastructure inspections, and the Edwards Aquifer Authority administers permitting for groundwater pumping. Although there is no formal hillside zoning overlay in the city sense, the cumulative effect creates a strict regulatory environment for hill-country slopes in unincorporated Bexar County.
Building in the Recharge Zone without an approved water pollution abatement plan triggers TCEQ enforcement, plat hold, and possible cease-and-desist orders.
