The following table lists minimum and maximum widths (in feet) and turning radii for various types of driveways:
Nominal Width | Agricultural | Residential | Commercial | Industrial/Retail | ||||
Min. | Max. | Min. | Max. | Min. | Max. | Min. | Max. | |
One Way | - | - | 12 | 14 | 14 | 20 | 14 | 26 |
Two Way | 14 | 20 | 12 | 24 | 26 | 30 | 26 | 30 |
Right Turn Radius | 25 | 35 | 15 | 25 | 25 | 35 | 35 | 75 |
This table assumes one lane for ingress and one lane for egress.
Driveway widths shall be measured perpendicular to the centerline of the driveway at the street right-of-way line. Driveways that enter a public roadway at traffic signals shall have the number of lanes as determined by a capacity analysis.
