Administrative Agency—The appropriate person or office of a political subdivision which is responsible for the administration and enforcement of the regulations prescribed herein. The administrative agency is set forth in Section 3 of these regulations.

B.

Airport—Houston Executive Airport, located in Waller County, Texas; including the ultimate development of that facility.

C.

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 Houston Executive Airport is 168 feet above mean sea level (MSL).

D.

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.

E.

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 5 of these regulations. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.

F.

Approach, Conical, Horizontal, and Transitional Zones—These zones are set forth in Section 4 of these regulations and are depicted in Figure 1, below.

G.

Board of Adjustment—A board so designated by these regulations as provided in Texas Local Government Code, § 241.032. Provisions for the board of adjustment are set forth in Section 9 of these regulations.

H.

Conical Surface—A surface extending outward and upward from the periphery of the horizontal surface at a slope of twenty (20) feet horizontally for each one (1) foot vertically for a horizontal distance of four-thousand (4,000) feet.

I.

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.

J.

Height—For the purpose of determining the height limits in all zones set forth in these regulations and shown on the hazard zoning map, the datum shall be height above mean sea level (MSL) elevation as measured in feet.

K.

Horizontal Surface—A horizontal plane one-hundred fifty (150) feet above the established airport elevation which in plan coincides with the perimeter of the horizontal zone.

L.

Nonconforming Use, Structure, or Tree—Any structure, tree, or use of land which is inconsistent with the provisions of these regulations and which is existing as of the effective date of these regulations.

M.

Nonprecision 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 nonprecision instrument approach procedure has been approved or planned. Planned Runway 18R/36L is considered a nonprecision instrument runway.

N.

Obstruction—Any structure, tree, or other object, including a mobile object, which exceeds a limiting height set forth in Section 5 of these regulations or is an airport hazard.

O.

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 18/36 at Houston Executive Airport is considered an other than utility runway.

P.

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.

Q.

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 18/36 at Houston Executive Airport is considered a precision instrument runway.

R.

Primary Surface—A 7,400-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.

S.

Runway—A defined area on the airport prepared for the landing and taking off of aircraft along its length. The current length of Runway 18/36 at Houston Executive Airport is 6,610 feet. The length of the ultimate runway configuration of Runway 18/36 at Houston Executive Airport is 7,780 feet. The length of the ultimate parallel 18R/36L is 7,000 feet.

T.

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.

U.

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 precision 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 five-thousand (5,000) feet measured horizontally from either edge of the approach surface and perpendicular to the extended runway centerline.

V.

Tree—Any type of flora and an object of natural growth.
