When the enforcing officer has reason to believe or observes that the accumulation and the storage of abandoned, wrecked, dismantled or inoperative vehicles or parts thereof on public or private property constitutes a public nuisance as described in Section 10.68.010, he or she shall immediately investigate the same. In the performance of such investigation the enforcing officer and his or her designees may enter upon private or public property to examine a vehicle or parts thereof and to obtain information as to the identity and the ownership thereof. The police department and health officer of the city shall assist in such investigation and enforcement as needed. (Prior code § 3218.5)
