(2) Variances. Any person who owns, controls, or operates any sound source which does not comply with section 6.750 of this code may apply to the city manager for a variance. As used herein, “city manager” includes a designee of the city manager.
(a) Application. An application for a variance shall be in writing on a form provided by the city, contain the information required by the city manager, and be accompanied by a fee in an amount set under section 2.020 of this code. No application shall be considered received until all required information and the fee have been submitted.
(b) Public notification. The city shall give written notice of the application to any officially recognized neighborhood association in whose boundaries the sound source is located. The city shall also post written notice at the sound source location and provide copies of the notice to owners and occupants of properties located within 300 feet of the sound source location. The notice shall state the date by which the application will be considered, the nature of the variance to be considered, and where persons may file written comments regarding the application.
1. The city manager shall grant or deny the variance within 14 days of receiving a complete variance application. The time for decision may be extended to 30 days if a public hearing on the application is held.
2. The city manager may, on the city’s manager’s own motion, hold a public hearing on the application before deciding to grant or deny the variance.
3. The city manager may grant a variance after considering the written application for variance, any written comments, and the applicant’s compliance with variance conditions previously imposed. The variance may be granted by the city manager when it appears that compliance with the standards from which the variance is sought will produce unnecessary hardship to the applicant without equal or greater benefit to the public or that the purposes of the noise disturbance provisions can be served without a strict application thereof.
4. The city manager may impose limitations and conditions granting the variance in order to protect affected persons from the noise disturbance. A violation of any such condition or limitation shall constitute a violation of section 6.075 of this code and grounds for revocation of the variance.
5. A decision to grant or deny a variance shall be in writing and shall state the reasons for such decision. The city manager shall notify the applicant of the decision and shall make it available to any person who has submitted written comments on the application.
6. The city manager may revoke a variance without a hearing upon finding that:
a. The applicant has provided false or misleading information, or omitted disclosure of a material fact, on the application or related material;
b. The applicant is operating the sound source in violation of this code or applicable local, state or federal law;
c. The applicant has violated a condition of variance approval; or,
d. New information shows that the permitted activity or device would endanger property or the public health or safety.
7. The action of the city manager in denying a variance application or in revoking an issued variance may be appealed in the manner provided by section 2.021 of this code. The decision of a hearings official on any such appeal is final. The action of the city manager in approving a variance may be appealed under the same procedures if such appeal can be decided in a timely way.
