Jurisdiction Notes

Denton is a rapidly growing city in the DFW metroplex with a Phase II MS4 permit. The University of North Texas and Texas Woman's University campuses may have separate institutional stormwater plans. Projects in the ETJ should verify applicable jurisdiction — Denton County (unincorporated) standards may apply in the ETJ.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
Disclaimer: This information is provided for general reference only. Always verify requirements directly with City of Denton — Development Services Department, Engineering Division and the agency website before beginning construction.
