(1) The procedure provided by sections 6.080 to 6.105 is not exclusive but is in addition to procedures provided by other laws. The city manager or the manager’s designee may proceed to summarily abate a nuisance which unmistakably exists and which imminently endangers the environment, human life, health or property. The cost of such abatement may be assessed as provided in section 6.100.

(2) The abatement of a nuisance under this section and the assessing of the costs therefor are not a penalty for violating this code but are additional remedies.
