Discussion and Review of Tiffin Municipal Code Revisions – Preparation for Setting the Public Hearing — Tiffin City Code - DRAFT

CHAPTER 166 ESTABLISHMENT OF ZONING DISTRICTS AND THE OFFICIAL ZONING MAP procedure outlined in Paragraph F. Administrative determinations made in conjunction with the analysis may be appealed according to Paragraph H. J. Revocation of Permits. If an alleged violation is determined to be valid by the independent engineering analysis, any permits previously issued in conjunction with the established use, building, or structure are void and the operator must cease operation until the violation is remedied. Failure to cease operation within two days of notice to do so by the City constitutes an violation of this Zoning Code and the penalty provision cited in Section 165.32 may be imposed. K. Technical Provisions. (1) Noise. To measure the intensity and frequency of sound, the sound level meter, the octave band analyzer, and the impact noise analyzer may be employed. The flat network and the fast meter response of the sound level meter may be used. Sounds of short duration that cannot be measured accurately with the sound level meter, may be measured with the impact noise analyzer. Octave band analyzers calibrated in the preferred frequencies (American Standards Association S1 6-1960, Preferred Frequencies for Acoustical Measurements) must be used with the following tables. The suspected perpetrator will be required to hire, at the approval of the City, a consultant to measure, record, and report to the Council results about compliance with this Code. All costs shall be the responsibility of the property owner. (2) Maximum Permitted Sound Level.
