Jurisdiction Notes

Edinburg is the seat of Hidalgo County and the largest city in the McAllen metropolitan area by county seat status, though McAllen is larger by population. The city is home to UTRGV, a growing research university. The Rio Grande Valley is one of Texas's fastest-growing regions, with significant commercial and residential development. The flat alluvial plain topography and interconnected irrigation/drainage canal system of the RGV create a unique stormwater management environment. Hidalgo County has multiple drainage districts with independent jurisdiction over canal systems.

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