Maximum Number Allowed: Single family residences shall be permitted to have only one driveway per lot, except if a lot has a minimum lot frontage of ninety feet (90'), then a circular driveway consisting of two (2) drives may be allowed. All other uses shall be allowed the number of driveways as approved by the Board of Trustees upon recommendation by the Community Development Department.
Widths: The maximum width for driveways for single family residences including circle drives shall be ten feet (10') at the sidewalk line and sixteen feet (16') at the curb; provided, that where a two car or three car garage is located within thirty feet (30') of the property line, the driveway shall not exceed twenty feet (20') at the sidewalk line or twenty-six feet (26') at the curb or thirty feet (30') at the sidewalk line and thirty-six feet (36') at the curb, respectively. No driveway shall encroach upon any portion of the parkway in front of the adjoining property. The maximum width for driveways for all other uses shall be as approved by the Board of Trustees upon recommendation by the Department of Engineering. 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.
Driveway Aprons: Single family residential driveway aprons shall have a maximum width of ten feet (10') for one (1)-car driveways, a maximum width of twenty feet (20') for two (2)-car driveways, and a maximum width of thirty feet (30') for three (3)-car driveways, measured at the sidewalk; and shall flare to a width three feet (3') greater at the curb line. All residential aprons shall have a minimum concrete thickness of six inches (6") and a granular bedding base of two inches (2"). 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.
