In addition to the definitions provided above, a permanent nuisance is also a nuisance of such a character that its continuance is necessarily an injury which will continue without change, unless Council takes such action to cease any like nuisance from becoming established and reoccurring at the particular location. It is not enough to show a slight interference to the public welfare and such will not be restrained unless the type of business or manner of operation is injurious to the public health, safety and welfare of the community or has a tendency to promote unlawful behavior or behavior which is considered by the City Administration, including its health and/or safety officials, to be a menace to public order and safety.
