Definitions. As used in this Section, unless the context otherwise requires:
AIRPORTAny airport now existing or hereafter created within the City of Marshall.
AIRPORT ELEVATIONThe highest point of an airport's usable landing area measured in feet from mean sea level.
AIRPORT HAZARDAny structure or object of natural growth located on or in the vicinity of a public airport, or any use of land near such airport, which obstructs the airspace required for the flight of aircraft in landing or takeoff at such airport or is otherwise hazardous to such landing or takeoff of aircraft.
HEIGHTFor the purpose of determining the height limits in all zones set forth in the Section and shown on the Zoning Map, the datum shall be mean sea level elevation unless otherwise specified.
HELIPORT PRIMARY SURFACEThe area of the primary surface coincides in size and shape with the designated landing and takeoff area of a heliport (runway). This surface is a horizontal plane at the elevation of the established heliport elevation.
NON-PRECISION-INSTRUMENT RUNWAYA runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in non-precision-instrument approach procedure has been approved or planned, and for which no precision approach facilities are planned or indicated on an FAA planning document or military service's military airport planning document.
NONCONFORMING USEAny preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this Section or an amendment thereto.
PERSONAn individual, firm, partnership, corporation, company, association, joint stock association, or governmental entity. It includes a trustee, receiver, assignee, or similar representative of any of them.
PRECISION INSTRUMENT RUNWAYA runway having an existing instrument approach procedure utilizing an Instrument Landing System (ILS) or a Precision Approach Radar (PAR). It also means a runway for which a precision approach system is planned and is so indicated on an FAA-approved airport layout plan; a military service's approved military airport layout plan; any other FAA planning document, or military service's military airport planning document.
PRIMARY SURFACEA surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends two hundred (200) feet beyond each end of that runway; but when the runway has no specially prepared hard surface, or planned hard surface, the primary surface ends at each end of that runway. The width of the primary surface of a runway will be that width prescribed in Part 77 of the Federal Aviation Regulation (FAR) for the most precise approach existing or planned for either end of that runway. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line.
RUNWAYA defined area on an airport prepared for landing and takeoff of aircraft along its length.
STOL PRIMARY SURFACEAn imaginary plane, three hundred (300) feet wide, centered on the runway, its length extends one hundred (100) feet beyond each runway end. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line.
STRUCTUREAn object constructed or installed by man, including, but without limitation, buildings, towers, smokestacks, earth formation, and overhead transmission lines.
TREEAny object of natural growth.
UTILITY RUNWAYA runway that is constructed for and intended to be used by propeller driven aircraft of twelve thousand five hundred (12,500) pounds maximum gross weight and less.
VISUAL RUNWAYA runway intended solely for the operation of aircraft using visual approach procedures and no instrument designation indicated on an FAA approved airport layout plan, a military service's approved military airport layout plant, or by any planning document submitted to the FAA by competent authority.
