Drives, parking and circulation. The planned unit development makes adequate provision to provide necessary parking. Principal vehicular access is from dedicated public streets, and access points shall be designed to encourage smooth traffic flow with controlled turning movements and minimum hazards to vehicular or pedestrian traffic. With respect to vehicular and pedestrian circulation (including walkways, interior drives, and parking), special attention has been given to the location and number of access points to public streets, the width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic, adequate provision for service by emergency vehicles, and arrangement of parking areas that are safe, convenient, and do not detract from the design of proposed buildings and structures and the neighboring properties. Access points are limited through the use of cross access connections.
