New or Changed Driveways Need a County Culvert Permit
A driveway off a county road is also a drainage choice. If you cut a new driveway and culvert in Brazoria County, or change an existing one, get a driveway and culvert permit first.
The application goes to Brazoria County Engineering by fax, mail, hand delivery, or email. The county sizes and sets the culvert; the applicant supplies the approved materials. Do not have a contractor set a residential driveway culvert in county right-of-way on their own.
That detail matters. A culvert that is too small or set wrong can dam roadside drainage and push water toward a neighbor. Talk to Engineering before a contractor moves dirt.
