In city-owned parking lots and ramps, the Council may limit the sizes and types of motor vehicles to be parked thereon, hours of parking and prescribed method of parking, provided that the limitations and restrictions are marked or sign-posted thereon. It is unlawful to park or leave standing any vehicle backed into a parking place, to drive in a direction opposite the flow of traffic marked by “one-way” signs or arrows, or to park any vehicle in any city-owned parking lot or ramp contrary to the restrictions or limitations marked or sign-posted therein.
