Section 6 Prerequisites to Issuance of Building Any application for a City of permit pertaining to land located in an Aircraft compliance with the provisions of this ordinance permit. Section 7 Establishment of Zones or Occupancy Permit building or occupancy Noise Zone must demonstrate prior to the issuance of such The following Aircraft Noise Zones are hereby established ordinance of Aircraft Noise Zone I Aircraft Noise Zone II Aircraft Noise Zone III Aircraft Noise Zone IV Aircraft Noise Zone A Aircraft Noise Zone B Aircraft Noise Zone C Aircraft Noise Zone D as part of the zoning Applies to Minneapolis -St. Paul International and St. Paul Downtown airports Applies to Airlake, Anoka County/Blaine, Crystal, Flying Cloud, Lake Elmo and South St. Paul Municipal airports The boundaries of the Aircraft Noise Zones are as delineated on the diagram attached hereto for the following airport(s) Section 8 Noise Compatibility Tables The Noise Compatibility Tables are adapted from the Metropolitan Council's Guidelines for Land Use Compatibility with Aircraft Noise. The Noise Reduction Level numbers, expressed in dBA, specify for each type of land use the amount of interior sound level reduction necessary for the use to be compatible in the applicable Aircraft Noise Zone. All construction or reconstruction requiring a building permit and located within an Aircraft Noise Zone (except remodeling or rehabilitation of an existing residential building) shall be constructed in such a way that the applicable noise level reduction requirements contained in the Noise Compatibility Tables are met or exceeded. Where a particular structure contains different land uses, the more stringent requirements of the applicable table shall apply, except where it is architecturally possible to achieve the appropriate noise reduction level for each different use, and the uses are acoustically separated by a wall or partition with a minimum STC of 25. Section 9 Enforcement The City of building inspector is authorized and directed to enforce the provisions of this ordinance pursuant to Sections 10 and 11. Section 10 Plans and Specifications A.
