The application shall contain, in addition to such information as shall be required by the Chief of Police, information demonstrating that bringing the source of sound for which the variance is sought or the activity involved into compliance with this Chapter would cause an unreasonable hardship for the applicant, the community or for other persons. Upon receiving such an application, the Clerk shall submit it to the Mayor. Upon receipt of an application, the Mayor shall cause such investigation as he/she deems necessary to be made concerning the application. This investigation may include, but need not be limited to, consulting with such departments as he/she may deem necessary or desirable. The Mayor, subject to the provisions of Subsection (D) below may, in his/her discretion, cause a public hearing to be held on any application for a noise variance. If no public hearing is held, the Mayor, subject to the provisions of Subsection (D) below, shall allow interested parties to submit written comments concerning an application for a noise variance. The applicant shall, prior to the investigation of the application by the Mayor, cause a public notice of the application for a noise variance to be published at least twice in a daily newspaper of general circulation published in the City in a form prescribed by the City Clerk.
D. 
The Mayor, in addition to such other investigation as he/she may deem necessary:
1. 
Shall require applicant to show that the notice requirements herein provided for have been met;
2. 
Shall permit applicant to offer such evidence as it desires to establish applicant's position that a variance should be granted;
3. 
Shall permit those opposing applicant's request for a variance to offer evidence in opposition to the granting of a variance;
4. 
May, in his/her discretion, refuse to receive or hear evidence that is cumulative and may reasonably limit the time allowed to present evidence by those supporting and those opposing the application.
E. 
The Mayor shall consider all evidence received pursuant to this Section and based upon this evidence and the results of his/her investigation shall make a recommendation to the City Council as to whether a noise variance should be granted. The Mayor shall make his/her recommendation based upon the factors set out in Subsection (F) and shall state the reasons for his/her recommendation in writing. The application and the recommendation of the Mayor shall be placed on the agenda of the City Council and shall be considered in due course according to the rules of the City Council. In deciding whether to grant the noise variance, the City Council shall consider the factors set out in Subsection (F) below. The City Council shall, by resolution, grant or deny the variance. If a resolution approving a noise variance is passed, the City Clerk shall issue a noise variance subject to the terms of this Section.
F. 
The following factors shall be considered in determining whether to grant the variance:
1. 
The balance of the hardship to the applicant, the community and other persons in not granting the variance against the adverse impact on the health, safety and welfare of persons adversely affected and any other adverse effects of the granting of the variance.
2. 
The number, if any, of previous variances granted to the applicant or for the same location or activity.
3. 
The nearness of any residence or residences or any other use which would be adversely affected by noise in excess of the limits prescribed by the Chapter.
4. 
The sound level of the sound to be generated by the event or activity.
5. 
Whether the type of noise to be produced by the event is usual or unusual for the location or area for which the variance is requested.
6. 
The density of population of the area in which the event or activity is to take place.
7. 
The time of day or night which the activity or event will take place.
8. 
The nature of the sound to be produced including, but not limited to, whether the sound will be steady, intermittent or of a repetitive impulse nature.
G. 
Neither the Mayor nor the City Council shall consider the communicative content of the activity or event in determining whether to grant or deny a variance. The rights of all interested persons to due process of law and equal protection of law shall not be denied.
H. 
Variances shall only be granted subject to the following conditions:
1. 
The event or activity for which the permit is sought shall be held in a public place.
2. 
The event or activity for which the permit is sought shall be open to the public. There shall be no discrimination on the basis of race, color, creed, national origin or sex.
3. 
Variances issued shall be subject to such reasonable conditions as the City Council shall require including, but not limited to:
a. 
Limiting the days of the week for which the variance is valid.
b. 
Limiting the number of days for which the variance is valid.
c. 
Limiting the hours of the day or days for which the variance is valid. Such conditions shall be noted on the variance issued to the applicant and non-compliance with any condition of the variance shall terminate the variance and subject the applicant, event or activity to the provisions of this Chapter. The variance shall not be valid unless all conditions thereof are agreed to by the applicant or its duly authorized officer or agent, in writing.
I. 
Any variance issued pursuant to this Section shall be kept at the site of the event or activity for which the variance was obtained. The variance shall be displayed, on request, to any Law Enforcement Officer, environmental protection department employee or park patrol officer. The requirements of this Chapter are made express conditions of the granting of the variance and failure to comply with these conditions shall cause the variance to terminate as provided for in Subsection (H) of this Section.
J. 
The City Council, in granting or denying a variance pursuant to this Section, shall be an administrative body, acting in a quasi-judicial capacity, subject to review as provided in State Statutes pertinent to administrative proceedings.
