Wayne County Zoning Ordinance Section 50.8 of the Wayne County Zoning Ordinance outlines the Airport Height Overlay . The purpose of the Overlay is to promote the safe conduct of aircraft in the vicinity of an airport , to prevent creation of conditions hazardous to aircraft operation , to prevent loss of life and property , and to encourage development which is compatible with airport use characteristics .
Within the Overlay , no use is allowed within the regulated area that would interfere with navigation , radio communication , or otherwise create a hazard to aircraft operations . Additionally , no structure is allowed to be constructed or maintained that would exceed maximum imaginary surface heights less ten feet . The imaginary surfaces are taken from Federal Aviation Regulations , Part 77 promulgated by the FAA and DOD Unified Facility Criteria 3‐260‐01 Airfield and Heliport Planning and Design . The Airport Height Overlay is divided into sub‐areas consistent with the FAA Part 77 .
Table 5.23‐2 provides analysis of allowable building heights for each zoning district in Wayne County where they occur in each imaginary surface . Green indicates compatibility and yellow indicates potential incompatibility , depending on the structure height .
Determining whether a structure constitutes a vertical obstruction is based on the georeferenced location of the structure , the structure height above ground level relative to the airfield , and which imaginary surface the structure is within . Therefore , it is not possible to know whether a structure constitutes a vertical obstruction without knowing and assessing these factors . However , the following information is provided for guidance purposes .
• Incompatible development can include n structures , within imaginary surfaces , and Approach‐Departure Clearance Surfaces at Seymour Johnson AFB .
• There is only one vertical obstruction sur AFB which is a communications tower loc Surface .
Height Regulations Surroun AFB Need to enhance the City of County regulations for height surfaces . Regulations only ref FAA Part 77 , but lack clarity o applied .
Compatibility Assessment Jurisdictions surrounding a military installation various vertical obstructions and how they can operations and missions . General development energy conservation systems or any other struc causing incompatible development can ultimate day‐to‐day activity .
Incompatible maximum heights within a jurisdic obstruction for both military and civilian aviatio development is located within the military oper occur .
