For the purpose of this article, the following words, terms, and phrases shall have the meaning ascribed to them below, except where the context clearly indicates a different meaning:
Administrative agency.The appropriate person or office of a political subdivision, which is responsible for the administration and enforcement of this article. The administrative agency is set forth in section
19-68 of this article.
Airport.The Eastland Municipal Airport, Eastland, Texas, including the ultimate development of that facility.
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 Eastland Municipal Airport is 1468.0 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 centerline, extending outward and upward from each end of the primary surface and at the same slope as the approach zone height limitation slope set forth in section
19-70 of this article. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.
Board of adjustment.A board so designated by this article as provided in Texas Local Government Code, section
241.032. Provisions for the board of adjustment are set forth in section
19-74 of this article.
Conical surface.An imaginary surface which extends upward and outward from the outer limits of the horizontal surface for an additional, horizontal distance of 4,000 feet at a slope of 20H:1V measured in a vertical plane.
Hazard to air navigation.An obstruction or use of land determined to have a substantial adverse effect on the safe and efficient utilization of navigable airspace.
Height.For the purpose of determining the height limits in all zones set forth in this article and shown on the hazard zoning map, the datum shall be height above mean sea level (MSL) elevation, as measured in feet.
Horizontal surface.A horizontal plane 150 feet above the established Eastland Municipal Airport elevation of 1468. The horizontal surface is constructed by swinging arcs around the end of the primary surface, which is aligned (longitudinally) with each runway and extends 200 feet from each runway end. The radius of the horizontal surface’s arcs for all runways designated as non-precision or precision instrument runways is 10,000 feet.
Nonconforming use, structure, or tree.Any structure, tree, or use of land which is inconsistent with the provisions of this article and which is existing as of the effective date of this article.
Non-precision instrument runway.A runway having an existing instrument approach procedure utilizing air navigation facilities or other equipment that provides only horizontal guidance or area type navigation equipment. This also includes a runway for which a non-precision instrument approach procedure has been approved or planned. Runway 17-35 is considered a non-precision instrument runway.
Obstruction.Any structure, tree, or other object, including a mobile object, which exceeds a limiting height set forth in section
19-70 of this article or is an airport hazard.
“Other than utility” runway.A runway designed for and intended to be used by propeller driven aircraft of more than twelve thousand five hundred (12,500) pounds maximum gross weight and jet powered aircraft. Runway 17-35 at the Eastland Municipal Airport is considered an “other than utility” runway.
Person.An individual, firm, partnership, corporation, company, association, joint stock association, or body politic and includes a trustee, receiver, assignee, administrator, executor, guardian, or other representative.
Precision instrument runway.A runway having an existing instrument approach procedure utilizing air navigation facilities or other equipment which provide both horizontal and vertical guidance. This also includes a runway for which a precision instrument approach procedure has been approved or planned. Runway 17-35 at the Eastland Municipal Airport would be considered a precision instrument runway if in the future, LPV instrument approach(es) are provided for this runway.
Primary surface.A 500-foot wide surface longitudinally centered on the runway extending the full length of the ultimate runway configuration plus two hundred (200) feet beyond each ultimate end of the runway. The elevation of any point on the primary surface is the same as the nearest point on the existing or ultimate runway centerline.
Runway.A defined area on the airport prepared for the landing and taking off of aircraft along its length. The zoned length of Runway 17-35 at the Eastland Municipal Airport is 5,000 feet.
Structure.An object, including a mobile object, constructed or installed by man including, but not limited to, buildings, towers, cranes, smokestacks, poles, earth formations, overhead power lines, and traverse ways. Traverse ways are considered to be the heights set forth in 14 C.F.R. part
77.23.
Transitional surfaces.Surfaces extending perpendicular to the runway centerline and the extended runway centerline outward from the edges of the primary surface and the approach surfaces at a slope of seven (7) feet horizontally for each one (1) foot vertically to where they intersect the horizontal surface. Transitional surfaces for those portions of the approach surface which extend through and beyond the limits of the conical surface extend at a slope of seven (7) feet horizontally for each one (1) foot vertically for a distance of 5,000 feet measured horizontally from either edge of the approach surface and perpendicular to the extended runway centerline.
Tree.Any type of flora and an object of natural growth.
