Water Quality Standards

Impervious Cover Limit
Portions of New Braunfels are within the Edwards Aquifer Recharge Zone or Contributing Zone — EAA permit required for development on regulated land; portions near Comal Springs have extreme water quality sensitivity; impervious cover limits and water quality controls required by EAA
On-Site Treatment Required
No
Detention Required
Yes
Detention Standard
Detention required to limit post-development peak flows to pre-development levels for 2-, 5-, 10-, 25-, and 100-year storms per City of New Braunfels and Comal County Drainage Criteria; Comal and Guadalupe rivers are sensitive receiving waters
Turbidity Standard
No numeric NTU limit; discharges must comply with TCEQ TXR150000 and not degrade Comal River, Guadalupe River, or Comal Springs water quality

Local SWPPP / Drainage Plan

Local Plan Required
Yes
Plan Name
SWPPP per TCEQ TXR150000; drainage report required for local permit
PE Stamp Required
Yes
Drainage study prepared by a Texas PE required for grading permits. New Braunfels is home to Comal Springs, the largest springs in Texas, and the headwaters of the Comal River — one of the shortest rivers in the world and a federally protected habitat for the fountain darter (endangered). EAA permit and USFWS coordination may be required for projects near the springs. The Guadalupe River generates significant tourism (tubing) and is sensitive to turbidity and recreational-use impacts.

Local Inspection Requirements

Jurisdiction Notes

New Braunfels is in Comal County, one of the fastest-growing counties in the U.S., between San Antonio and Austin on I-35. The city is home to Comal Springs (largest springs in Texas), the source of the Comal River (which flows through the historic Landa Park), and world-famous tubing on the Guadalupe River. The ecological significance of Comal Springs — with its federally endangered fountain darter — creates strict environmental oversight for any development with aquifer recharge or discharge implications. New Braunfels has evolved from a small German heritage community to a major growth center with significant residential, resort, and retail development.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
