The procedure provided by this chapter is not exclusive, but is in addition to the procedures provided by other ordinances. A fire official, a law enforcement officer, or any other county official, may proceed summarily to abate a health or other nuisance which unmistakably exists and which imminently endangers human life or property. Any summary closure proceeding shall be based on evidence showing that nuisance activities exist or have occurred on the property and that emergency action is necessary to avoid an immediate threat to public welfare and safety. Proceedings to obtain an order of summary closure shall be governed by the provisions of the state for obtaining temporary restraining orders. In the event of summary closure, the county is not required to comply with the notification procedures set forth in section 3-1-6 of this chapter. (1998 Code § 8.16.170)
