  • (1) 
    Statement of Purpose. The City of West Allis recognizes that excessive noise and vibration are serious threats to the public health and welfare, public safety, quality of life and property values. Current science and technology permit abatement of noise and vibration sources which were not available in the past. Therefore, it is the policy of the City to prevent and abate excessive noise and vibration which may jeopardize the public health, safety or welfare or which would cause harm to property values or which would impair the quality of life within the City.

    1. 
    After the close of the hearing, the Committee shall deliberate and reach a decision. Based on the evidence presented at the hearing, the Committee shall recommend to the Common Council whether a variance permit should be issued and under what conditions the Committee finds necessary to protect the public health, safety and welfare, including a schedule for achieving compliance with noise and vibration limitations. In deciding whether to recommend granting the permit, the Committee shall balance the hardship to the applicant, the community, and other persons; the impact on the health, safety, and welfare of the community; the effect on the property in the area; and any other impact that the granting of the variance may have. The Committee shall prepare findings on factual matters, conclusions of law, and a recommendation on what action, if any, should be taken with regard to the license(s) at issue. The report shall be filed with the City Clerk/Treasurer within twenty (20) days, and the Clerk shall mail a copy of the report to the last-known address of the variance applicant, Health Commissioner, and any person(s) who claim to be adversely affected by the allowance of the variance permit. The findings and recommendations shall be distributed to each member of the Common Council.

    The variance applicant, Health Commissioner, and any person(s) who claim to be adversely affected by the allowance of the variance permit may file a written statement or response to the findings and recommendation, including objections, exceptions, and arguments of fact and law. A written statement must be filed with the City Clerk/Treasurer before the close of business on a day that is at least three working days prior to the date set for determination by the Common Council. Copies of written statements shall be provided to each member of the Common Council at least twenty-four (24) hours before any vote on the matter is scheduled before the Common Council.
    (f) 
    Common Council Determination.
    1. 
    Not less than five (5) working days prior to the matter being scheduled before the Common Council, the Clerk/Treasurer shall notify the variance applicant and any person(s) who claim to be adversely affected by the allowance of the variance permit by United States first-class mail, postage prepaid, sent to the last known address, that the Common Council will convene to determine the matter.
    2. 
    Unless an Alderperson states that he/she has not read the findings and recommendations, and written statements, if any, the matter shall proceed to debate amongst members of the Common Council. Neither the variance applicant nor any person(s) who claim to be adversely affected by the allowance of the variance permit shall be permitted to make oral arguments.
    3. 
    The Common Council shall determine by a majority vote of those in attendance and voting whether to adopt the recommendation of the Committee or make such modification as is deemed appropriate. Such vote shall be a roll call vote, and such hearing shall constitute the final determination of the matter. The Clerk/Treasurer shall notify the variance applicant and any person(s) who claim to be adversely affected by the allowance of the variance permit by United States first-class mail, postage prepaid, sent to the last known address, of the Common Council's decision.
    (g) 
    The permit, if granted, shall contain a time limit for such activity. Variances exceeding two (2) years may be granted only in exceptional cases, including those for which, in the opinion of the Committee, control technology is unavailable or available only at a prohibitive cost. Noncompliance with any conditions imposed on the variance shall terminate the variance and subject the person or corporation holding it to those provisions of this section for which the variance permit was granted.
    (h) 
    Extension and Modification. Application for extension of time limits or modification of other conditions specified in the variance permit shall be treated like applications for an initial variance, except that the Common Council must find that the need for such extension or modification clearly outweighs any adverse impacts of granting the extension or modification.
    (i) 
    Judicial Review. Any party to a proceeding resulting in a final determination may seek review thereof by certiorari within thirty (30) days of receipt of the final determination.
    1.

In default of payment thereof, the person shall be imprisoned in the Milwaukee County House of Correction until such forfeiture and costs are paid, but not more than the number of days set forth in Section 800.095(1)(b)1 of the Wisconsin Statutes. Each day that any violation continues shall be considered a separate offense.
    (13) 
    Severability. If any provision, clause, sentence, paragraph, or phrase of this section or the application thereof to any person or circumstances is held, for any reason, by a court of competent jurisdiction, to be invalid or unconstitutional, such decision shall not affect the validity of other provisions or applications of the provisions of this section which can be given effect without the invalid provision or application, and to this end, the provisions of this section are declared to be severable.
