For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
AIRPORT. Cleburne Regional Airport.
AIRPORT ELEVATION. The established elevation of the highest point on the runway, either existing or planned, at the airport measured in feet above mean sea level (MSL). The airport elevation of the Cleburne Regional Airport is 854.2 feet above mean sea level (MSL).
AIRPORT HAZARD. Any structure, tree, or use of land which obstructs the airspace required for the flight of aircraft or obstructs or interferes with the control, tracking, and/or data acquisition in the landing, takeoff, or flight at an airport or any installation or facility relating to flight, tracking, and/or data acquisition of the flight craft; is hazardous to, interferes with, or obstructs such landing, takeoff, or flight of aircraft; or is hazardous to or interferes with tracking and/or data acquisition pertaining to flight and flight vehicles.
APPROACH SURFACE. A surface longitudinally centered on the extended runway center line, extending outward and upward from the end of the primary surface and at the same slope as the approach zone height limitation slope set forth in § 90.083 of this subchapter. In plan the perimeter of the approach surface coincides with the perimeter of the approach zone.
APPROACH, TRANSITIONAL, HORIZONTAL, AND CONICAL ZONES. These zones are set forth in § 90.082 of this subchapter.
BOARD OF ADJUSTMENT. A board appointed under § 90.088 of this chapter and as provided in Tex. Loc. Gov't Code § 241.032.
CITY MANAGER. The officer or person, or his or her designee, designated in § 90.087 to administer and enforce the regulations prescribed herein.
CONICAL SURFACE. A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 feet horizontally for each one foot vertically for a horizontal distance of 4,000 feet.
EXTRATERRITORIAL JURISDICTION (ETJ). The unincorporated area, not a part of any other municipality, that is contiguous to the corporate limits of the city, the outer limits of which are measured from the extremities of the corporate limits of the city outward up to the distance stipulated in Chapter 42 of the TEX. LOC. GOV’T CODE, as may be amended, according to the population of the city, and in which area the city may apply ordinances and regulations specifically provided by Chapters 42 and 241 of the TEX. LOC. GOV’T CODE, or other provisions of state law to be applied by the City of Cleburne, Johnson County, or the Cleburne-Johnson County Joint Airport Zoning Board within the extraterritorial jurisdiction.
HAZARD TO AIR NAVIGATION. An obstruction determined to have a substantial adverse effect on the safe and efficient utilization of the navigable airspace.
HEIGHT. For the purpose of determining the height limits in all zones set forth in this subchapter and shown on the zoning map described in § 90.082, the datum shall be height above mean sea level elevation as measured in feet, unless otherwise specified.
HORIZONTAL SURFACE. A horizontal plane 150 feet above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.
NONCONFORMING USE, STRUCTURE, OR TREE. Any preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this subchapter or an amendment thereto, which is existing as of the effective date of this subchapter, as amended.
NONPRECISION INSTRUMENT RUNWAY. A 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 nonprecision instrument approach procedure has been approved or planned. Within this subchapter, this term refers to Runway 15-33 as indicated on the adopted airport hazard zoning map described in § 90.082.
OBSTRUCTION. Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in § 90.083 of this subchapter.
PERSON. An individual, firm, partnership, corporation, company, association, joint stock association or government entity; includes a trustee, a receiver, an assignee, an administrator, an executor, a guardian, or a similar representative.
PRIMARY SURFACE. A 500-foot-wide surface longitudinally centered on the runway extending the full length of the ultimate runway configuration plus 200 feet beyond each ultimate end of the runway. The width of the primary surface is set forth in § 90.082 below. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.
RUNWAY. Runway 15-33, or other runway as indicated on the adopted airport hazard zoning map described in § 90.082 below. Runway 15-33 is a defined area of the Cleburne Regional Airport prepared for landing and takeoff of aircraft along its length. The zoned length of Runway 15-33 at the Cleburne Regional Airport is 5,697 feet. The planned ultimate length of Runway 15-33 at the Cleburne Regional Airport is 6,280 feet.
STRUCTURE. An object, including a mobile object, constructed or installed by man, including, but not limited to, buildings, towers, cranes, smokestacks, poles, earth formation, overhead transmission lines, and transverse ways. Transverse ways are considered to be the heights set forth in 14 C.F.R. Part 77.23.
TRANSITIONAL SURFACES. These surfaces extend outward at 90° angles to the runway centerline and the runway centerline extended at a slope of seven feet horizontally for each one foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces. Transitional surfaces for those portions of the precision approach surfaces, which project through and beyond the limits of the conical surface, extend a distance of 5,000 feet measured horizontally from either edge of the approach surface and at 90° angles to the extended runway centerline.
TREE. Any type of flora that is an object of natural growth.
