A. Sound attenuation, or the use of special construction methods or materials which are designed or have the effect of insulating interior spaces from exterior noise related to aircraft activity, is required in the airport restriction zones A, B and C, as set forth in section 21.76.220, or its successor, of this code. Certain types of uses are prohibited as incompatible unless they demonstrate sound attenuation to reduce the noise by a minimum specified decibel level.
B. Where sound attenuation is required, the following plans and reports shall be submitted to the building official for review to demonstrate compliance. No plans shall be approved and no permits shall be issued for the new construction or alteration of structures located within such zones unless they comply and demonstrate the ability to perform the necessary sound attenuation. No certificate of occupancy shall be issued until actual performance demonstrates compliance, nor shall the building official approve plans or issue permits within such restrictive zones without receipt of the avigation easement in the form approved by the city attorney's office when required by section 21.76.230, or its successor, of this code. (Prior code § 5-18-1)
