Except in the case of an emergency or in the case of a person who has a valid right-of-way use permit or service parking permit, no person shall park or stand a vehicle in an alley within the city for purposes other than actively loading or unloading, or for the rendering of service to adjacent property. In the case of rendering service to adjacent property, no vehicle shall remain parked or standing beyond thirty minutes. Persons providing service requiring more than thirty minutes are required to obtain a city right-of-way use permit from the public works department (or designee) for each incident or an annual service parking permit from the city clerk (or designee). In no event shall vehicles parked in alleys obstruct or hinder vehicular or pedestrian travel. (Ord. 2180-96 § 17, 1996.)
