Jurisdiction Notes

Bryan is the county seat of Brazos County and the commercial twin to College Station, which is home to Texas A&M University. Bryan has industrial, manufacturing, distribution, and healthcare sectors that are distinct from the university-dominated economy of College Station. The Bryan-College Station metro is growing rapidly. The Post Oak Savanna ecoregion's sandy, acidic soils are highly erodible and require robust sediment control. The Brazos River Authority manages regional water resources including Lake Brazos.

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