The City Council, by motion or resolution, may establish parking time limits or prohibit parking on designated streets or parts of streets and have appropriate signs placed on the streets. When the signs are in place, it is unlawful for any person to park a vehicle in violation of the sign. No such time limits shall be effective unless a sign is erected and in place at the time of the alleged violation.
