On those streets which in the opinion of the public works director are too narrow to permit the safe passage of vehicles while other vehicles are parked on those streets, the public works director shall have the authority to recommend the adoption by the city council of a resolution prohibiting parking on one or both sides of those streets. Upon approval of a resolution prohibiting such parking by the city council, the public works director shall post appropriate signs and the police department shall begin enforcement of the parking restriction. (Ord. 428 § 1, 2010)
