Widths: The maximum width shall be in accordance with Section 6-406.B.
Grades and Curbs: Driveways shall conform to the existing sidewalk grade. Where it is necessary to break the existing curb for the driveway opening, the curb and gutter shall be completely removed and a new section constructed. Each such driveway shall be constructed and maintained so as to permit free and unobstructed passage or), over or across the same and in such a manner as not to interfere with the proper drainage and safe grading of streets. Gradual approaches to the regular sidewalk grade shall be one inch (1") above the gutter slab. The slope of any driveway and the approaches thereto shall not exceed two inches (2") to the foot in any direction. Each such driveway shall be so constructed and maintained that its surface at the point of crossing any sidewalk pavement shall be flush with the adjoining sections of such sidewalk.
Connection to Collector or Arterial Street: Driveways connecting to collector or arterial streets must provide an on site turn around. Where lots front both a local street and an arterial or collector street, no driveways shall be installed along the property line of the lot which fronts the arterial or collector street.

Multi-family development business, office research, and industrial district driveway aprons shall be constructed with ten foot (10') radius returns unless otherwise required by the Department of Engineering.
Concrete Thickness: All residential driveways shall have a minimum concrete thickness of five (5) inches and a granular base of two (2) inches minimum compacted thickness or an equivalent pavement section with a minimum structural number of 2.5.
New Driveway Aprons Abutting Existing Biketrails, Sidewalks or Curbs: New driveway aprons abutting existing biketrails, sidewalks or curbs shall be constructed to meet the grade of such sidewalks or curbs. If necessary, the sidewalk shall be relocated to accommodate the maximum driveway apron slope. The location and grade for driveway aprons, when no adjacent sidewalks or curb and gutter exists, shall match the adjacent parkway. The maximum slope of the driveway apron shall be eight (8) percent, and the minimum slope shall be two (2) percent.
