- Turbidity Standard
- No numeric NTU limit; discharges must comply with TCEQ TXR150000 and not degrade Onion Creek, Plum Creek, or Edwards Aquifer recharge features
Local SWPPP / Drainage Plan
- Local Plan Required
- Yes
- Plan Name
- SWPPP per TCEQ TXR150000; drainage report required for local permit
- PE Stamp Required

Drainage study prepared by a Texas PE required for grading permits. Kyle's location over the Edwards Aquifer Recharge Zone means many projects must comply with EAA water quality protection rules, which are among the most stringent in Texas. Impervious cover caps (15% over recharge zone, 35% over contributing zone with water quality controls) apply to EAA-regulated sites. Onion Creek has experienced repeated flooding and has FEMA flood maps that have been revised multiple times.
Local Inspection Requirements
- Requirements
- City of Kyle Development Services inspects grading permits at rough grading and final stabilization. Edwards Aquifer protection sites may require additional water quality inspections.
- Inspector Qualification
- No city-specific certification required beyond TCEQ SWPPP requirements

Jurisdiction Notes
Kyle is one of the fastest-growing cities in Texas and the nation, located on I-35 in Hays County between Austin and San Marcos. The city's explosive growth is driven by Austin metro expansion. Kyle's location over the Edwards Aquifer Recharge Zone creates significant regulatory complexity — EAA permit requirements are among the most stringent stormwater regulations in Texas. Onion Creek has been devastated by flash floods multiple times, prompting significant floodplain remapping and buyout programs. The combination of karst geology, flash flood risk, and rapid urbanization makes stormwater management especially challenging in Kyle.
Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
