Jurisdiction Notes

College Station is home to Texas A&M University, one of the largest universities in the United States, which generates significant ongoing construction activity with its own institutional TPDES permit. The Bryan-College Station metro is growing rapidly. The city is located in the Post Oak Savanna ecoregion where sandy soils can create rapid infiltration or significant erosion depending on saturation. Spring severe weather season requires active stormwater BMP maintenance.

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 College Station Public Works / Development Services and the agency website before beginning construction.
