Noise zones, for the purpose of this amendment, are defined by contours of the day-night sound level, according to the official zoning map of the city. The ANAP zones are intended to identify those areas in the vicinity of the MCAS and Yuma International Airport which require sound isolation to be included in the design and construction of proposed buildings.
(A) Performance standards. Standards of construction considered acceptable and in compliance with the intent and provisions of this amendment are provided in § 150-128. A building will generally be considered acceptable by the building official if it incorporates the applicable features described in § 150-128. Alternate materials and methods of construction may be permitted, provided such alternates are demonstrated to the satisfaction of the building official to be equivalent to those described.
(B) Acoustical analysis and design report. The applicant may elect to have a qualified architect or engineer examine the noise levels and needed building sound isolation requirements for a specific site. The analysis and design report signed by and prepared under the supervision of a qualified architect or engineer shall be submitted with the application for building permit. The report shall show the topographical relationship of the aircraft noise sources and the building site, identification of noise sources and their characteristics, predicated noise spectra at the exterior of the proposed building structure, basis for the predication (measured or obtained from published data), and effectiveness of the proposed construction showing that the prescribed interior day-night sound level is met.
