§ 130.057  TEMPORARY EXEMPTIONS.
   (A)   The City Manager is authorized to grant a temporary exemption from the maximum permissible sound levels established by this subchapter if such temporary exemption would be in the public interest and there is no feasible and prudent alternative to the activity, or the method of conducting the activity, for which the temporary exemption is sought.
   (B)   The following factors shall be considered by the City Manager in determining whether to grant a temporary exemption:
      (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 nearness of any residence or residences, or any other use which would be adversely affected by sound in excess of the limits prescribed by this subchapter.
      (3)   The level of the sound to be generated by the event or activity.
      (4)   Whether the type of sound to be produced by the event or activity is usual or unusual for the location or area for which the variance is requested.
      (5)   The density of population of the area in which the event or activity is to take place.
      (6)   The time of day or night which the activity or event will take place.
      (7)   The nature of the sound to be produced, including but not limited to, whether the sound will be steady, intermittent, impulsive, or repetitive.
   (C)   A temporary exemption must be in writing and signed by the City Manager or his or her appointed representative and must set forth the name of the party granted the exemption, the location of the property for which it is authorized, the date(s) and time(s) for which it is effective and the dB(A) level(s) authorized.
   (D)   A temporary exemption may be granted only for the period of time that is reasonably necessary to conduct the activity, which in no case may exceed 30 days.
