Free. No account, no email.
Key takeaways
- A secondary source says a 2014 ordinance requires a SWPPP on site for work on 1 acre or more, signed by a Texas engineer. We could not confirm either point.
- Bexar, Comal, Kinney, Medina and Uvalde counties are in the Edwards Aquifer program, where TCEQ must sign off before soil is disturbed.
- Only parts of those counties are in a zone. The map decides.
We could not read San Antonio's current stormwater text. The city-specific items below are marked "check with the city".
What should I check with the city?
- Whether the SWPPP must be signed by a Texas engineer. Check with the city.
- Erosion control permits, fees, fines and stop-work powers: not found. Check with the city.
- Edwards Aquifer sensitive-area rules from the San Antonio Water System: not read. Check with the city and SAWS.
- The city's stormwater review checklist: Development Services StormWaterReviewChecklist (we saw only its title).
FAQ
Do I need an engineer to sign my SWPPP in San Antonio?

Is my lot in the Edwards Aquifer?
