Upon the declaration of an emergency, there shall be no parking upon streets or sections of streets where temporary emergency no-parking signs are displayed. The Director of Police, or in his absence the ranking police officer, is authorized to declare an emergency and to direct the posting of said emergency no-parking signs when weather conditions, accidents, fires or public celebrations dictate or require the avoidance of hazards or other conditions which interfere with the free flow of traffic.
Any unoccupied vehicle parked or standing in violation of this article shall be deemed a nuisance and a menace to the safe and proper regulation of traffic, and any peace officer may provide for the removal of such vehicle. The owner shall pay the reasonable costs of the removal and storage which may result from such removal before regaining possession of the vehicle.
The effectiveness of this article is contingent on signs being erected as required by law.
