streets or sections of streets where temporary EMERGENCY NO PARKING
signs are displayed. The Chief of Police or, in his/her absence, the
ranking police officer is authorized to declare an emergency and to
direct the posting of EMERGENCY NO PARKING signs when weather conditions,
accidents, road construction, fire or public celebrations dictate
or require avoidance of hazards or other conditions which interfere
with the free flow of traffic. Notification that EMERGENCY NO PARKING
signs are being or will be posted shall be given to the operator or
owner of any vehicle which has been parked prior to the posting of
the signs.
