Summary
Property near Gulfport-Biloxi Regional Airport falls inside the Airport Environs and Airspace Zoning District (AEAZD), an overlay that layers noise and height rules onto whatever conventional district already applies. The Land Use Compatibility Overlay is split into three noise tiers, 65 to 70 LDN, 70 to 75 LDN, and 75 LDN and above, each with its own permitted-use table, and the Height/Airspace Overlay separately restricts structures near runway approach and transitional surfaces.
(a)Land Use Overlay subdistricts. The Gulfport-Biloxi Regional Airport Environs and Airspace Zoning District (AEAZD) Land Use Compatibility Overlay area is subdivided into three (3) subdistricts that represent the differing levels of noise impact. The geographic location of these districts is indicated on the city's official zoning map, having been duly adopted by the city as per the requirements of this zoning ordinance provision. The noise districts are as follows:1.The area within the 65 LDN to 70 LDN noise-exposure area.2.The area within the 70 LDN to 75 LDN noise-exposure area.3.The area within the 75 LDN and greater noise-exposure area.

Full Breakdown
The AEAZD, created to protect the airport's operations and the surrounding population, applies two separate sets of standards on top of a property's base zoning: a Land Use Compatibility Overlay tied to aircraft noise exposure, and a Height/Airspace Overlay tied to Federal Aviation Regulation Part 77 surfaces. The noise overlay's three subdistricts, the 65-70 LDN band, the 70-75 LDN band, and the 75-plus LDN band, are mapped from the Gulfport-Biloxi Regional Airport Authority's FAA-approved noise exposure map, and Table A of the ordinance sets out which land uses are compatible, compatible with restrictions, or prohibited in each band.
A use marked "Yes, with restrictions" needs written sign-off from the planning division administrator before it can proceed. Where a nonpermissible use or a use compatible only with restrictions is approved by variance, special exception or Planning Commission action, the applicant must convey an avigation easement to the Airport Authority covering the right of flight over the property, recorded with the Chancery Clerk of Harrison County's First Judicial District. The height overlay separately bars any building permit for a structure that would come within ten feet of penetrating the primary, approach, transitional, horizontal or conical surfaces defined under Part 77, unless the planning division administrator certifies no airport hazard results, and any work inside a runway protection zone needs the Airport Authority's development review before a permit issues.
Land surveyors working inside the AEAZD must note that fact on every plat, and the department of urban development's planning division is required to notify local surveyors and real estate professionals of the district's existence and restrictions.
Violations & Fines
An applicant who skips the required avigation easement, or who obtains a building permit inside the runway protection zone without the required Airport Authority development review, is out of compliance with the AEAZD and can have the permit denied or revoked. Because the AEAZD is part of the zoning ordinance, a violation of its standards falls under Section VIII(A)(4)(b)'s general zoning penalty: a misdemeanor, with the property owner, contractor and any other responsible party each subject to separate prosecution under Mississippi Code Ann. § 17-1-27.
