New Driveways Onto County Roads Need a Culvert Permit

A rural driveway in Collin County is more than gravel at the ditch. Any home or business driveway connecting to a county road needs a culvert or driveway permit under county roadway standards.

The culvert also has to meet drainage design rules. That permit sits under Public Works in the Civic Access portal, not the residential building-permit path that many people check first.

Get the permit before the contractor cuts the ditch. The county may inspect culvert size, spacing, drainage, and the road tie-in. Rebuilding a bad entrance later costs more than setting it right the first time.
