The city council finds and declares that vehicles which are on public or private property and which are in such a condition so as to constitute an imminent danger to the public are a public nuisance and a nuisance per se and should be removed by summary abatement to avoid injury to the public. Conditions which warrant summary abatement include, but are not limited to, permitting a vehicle to remain unattended on blocks, jacks or other means of raising the vehicle; broken glass and other sharp objects on the vehicle; flammable or other hazardous substances in or around the vehicle; and other conditions where an unattended vehicle or parts thereof pose an imminent danger to health, safety, or welfare of the public. For purposes of this section, "unattended" is defined as a vehicle upon which work is not actively being performed at the time the condition constituting a danger is observed. (Ord. 98-004 § 1; prior code § 61.06.612)
