Permits
Any work done in the road right-of-way must be permitted. This includes private and public accesses, utilities (gas, water, electric, cable TV, phone, etc.), or any other construction work in the road right-of-way.

Any private or public access that connects to a county or dedicated road will need to be permitted. A permit for a residential access is $75.00 and a commercial access is $150.00. A residential access must be no wider than 30 feet and a commercial access must be no wider than 50 feet. A copy of the contractors Excavation Bond to do work in Yellowstone County may be required. The Yellowstone County Public Works Department will review the access for proper sight distance.

Culvert piping (if applicable) must be sized for the appropriate drainage area and must be a minimum of 15 inches in diameter.
