Drainage study prepared by a Texas PE required for grading permits. Bryan is the county seat of Brazos County and the twin city to College Station (home to Texas A&M). Bryan has significant industrial, manufacturing, and logistics development separate from the university activity in College Station. The two cities share much infrastructure and coordinate on regional drainage. Sandy Post Oak Savanna soils require careful erosion control.

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.
