Spaces for parking of motor vehicles shall be marked off along public parking facilities by means of painted lines on the parking surface, by raised curbs, or by other suitable means so as to clearly delineate said space as a designated and authorized parking space for one vehicle. Directional arrows, stop signs, or stop bars and other traffic control devices shall be provided to assist and direct circulation within public parking facilities. Areas of public parking facilities not otherwise designated by painted lines or otherwise as parking spaces, shall be considered official "no parking" zones when indicated by posted signs or yellow paint applied to top and face of curb or by yellow painted lines on the parking surface unless otherwise posted.
