One focus of CARNP was to provide a safe roadway system and protect traffic capacity in order to minimize future construction costs. This guidelines applies only to homes and businesses located in the unincorporated area of Johnson County.

The number of driveways affects traffic safety, traffic capacity, and maintenance costs. CARNP addressed this issue by providing reasonable driveway restrictions along arterial roads. The number of driveways will be limited by driveway spacing requirements related to road frontage.

The table below indicates the maximum number of driveways that your property may have based on the road frontage. Sight distance, drainage and other factors may reduce the available driveway locations. Also, there may be deed restrictions, or restrictions on the subdivision plat which may limit driveway numbers and locations.
 
Please keep in mind that you may want to split your property at a later date. If all available driveways are used on one portion of your property, the new owner may not be eligible for a driveway on the new tract unless you remove an existing driveway. Shared driveways are also an option in areas where there is not sufficient frontage.
