The minimum for new installation of driveways is 15 inches in diameter and 30 feet in length, although some may require a larger diameter culvert. 

The Road District is not responsible for the installation or repair of culverts, although the Road Commissioner does have the authority to require the correct size culvert is being installed. We also require that 10 inches of course material be applied from the edge of the road to the culvert.

Check with the Road Commissioner if you have any questions on what your property requires.
