If no entrance permit is on file, you will need to apply for one. The entrance permit costs $50. We will need to know the top surface width of the driveway where it crosses the right of way. Residential driveways can be 16’ – 24’ wide and Commercial driveways can be 16’ – 30’ wide. A technician will go to the property to verify that the driveway conforms to our standards. The permit will be returned to you with any information needed to make the driveway conform. You can apply for the 911 address at the same time and on the same permit. We will need to know the approximate location of the entrance off the county road and where the building will be located.

Roads may be closed during construction to keep everyone safe or to allow materials to cure before traffic is allowed back on. Drivers not following the road closure signs are putting themselves and the workers in danger. Drivers that do not follow the signing may be ticketed and invoiced for any damage caused.

All (concrete, asphalt, sealcoat, rock, etc.) drives adjacent to the paving will receive a granular taper to allow for the difference in road elevation (approximately 8”) after paving. Additional rock is available for $15/ton (10 ton minimum) if the property owner would like more rock. Property owners can pay to have their paved drives adjusted at a cost of $6/square foot. The cost to adjust a typical driveway is approximately $2,200. The rock placement and paved drive replacement is limited to within the County right-of-way. Please contact the Engineer’s Office if you are interested in having your paved drive replaced.
