If, in the opinion of the department head, there exists a condition on any premises which is of such a nature as to be imminently dangerous to the public health, safety or welfare, which, if not abated according to the procedures of this code, would, during the pendency of the proceedings, subject the public to potential harm of a serious nature, the same may be abated forthwith without compliance with the provisions of this code. Abatement may include, but is not limited to boarding of windows, doors and other openings to city specifications, removal of junk and debris, and securing the perimeter of the property with fencing, gates or barricades (to prevent further occurrences of the nuisance activity). (Prior code § 61.09.901)
