22.8.C Access Requirements for Off-Street Vehicle Parking Areas
1. Each off-street vehicle parking space shall open directly upon an aisle or driveway of adequate width to provide access to a vehicle parking space. All off-street vehicle parking facilities shall provide access in a manner that least interferes with traffic movement. For all uses except single-family and two-family dwellings, the parking area shall be designed so that the driver of the vehicle proceeds forward into traffic rather than backs out.
2. All required off-street parking facilities shall have vehicular access from a street, alley, driveway, or cross-access connection.
3. Within off-street parking lots and structures, one-way traffic aisles shall be a minimum of twelve (12) feet in width and two-way traffic aisles shall be a minimum of twenty-four (24) feet in width. Furthermore, all aisles shall be designed in accordance with Figure 22-2.
