The location, width, number and composition of driveways and driveway aprons, for entrance and exit driveways to parking facilities, except for one and two-family dwellings, shall be as follows.
(a) Parking areas having a capacity of ten spaces or less shall have at least one single lane driveway having a minimum width of ten feet and a maximum width of 12 feet with the radius of the edge of the driveway apron of at least 30 feet, so that a vehicle may enter from or exit onto the curb lane without obstructing vehicles in other traffic lanes.
(b) Parking areas having a capacity of more than ten spaces shall have at least two single lane driveways, if possible, each having a minimum width of ten feet and a maximum width of 12 feet with the radius of the edge of the driveway apron of at least 30 feet, so that a vehicle may enter from or exit onto the curb lane without obstructing vehicles in other traffic lanes. If two single lane driveways are not possible, then there shall be at least one two-lane driveway having a minimum width of 18 feet and a maximum width of 24 feet with the radius of the edge of the driveway apron of at least 30 feet, so that a vehicle may enter from or exit onto the curb lane without obstructing vehicles in other traffic lanes.
(c) Upon approval by the Planning and Zoning Commission or the Director of Public Service, an entrance or exit driveway may be three lanes in width having a minimum of 27 feet and a maximum of 34 feet with the radius of the edge of the driveway apron of at least 30 feet, so that a vehicle may enter from or exit onto the curb lane without obstructing vehicles in other traffic lanes. No entrance or exit driveway shall exceed three lanes in width.
(d) For all parking areas having a capacity of more than ten vehicles, the centerline of the driveway apron shall be located not less than 75 feet from the nearest street intersection right-of-way line.
(e) Driveway aprons on the same property shall be spaced at not less than 100-foot intervals measured on the centerline of the driveways.
(f) All driveway aprons and driveways to parking facilities, except for one and two-family dwellings, shall be constructed so as to interfere as little as possible with the use of adjacent property and the flow of traffic on adjacent streets.
(g) The subgrade of all driveway aprons, except for one and two-family dwellings, shall consist of granulated slag, gravel or stone, the minimum thickness of which shall be three inches, and the surface of which shall be of rigid construction not less than six inches thick, which surface shall be level with the surface of the street pavement. The surface of all driveway aprons shall extend from the edge of the street pavement to the edge of the street right-of-way line unless the Director of Public Service determines that a shorter distance may be maintained without damage to the street pavement.
