This chapter shall be known and may be cited as the Hermiston Municipal Airport Hazard Zoning Ordinance.

(Ord. 1411, passed 4-27-82)

§151.02 Definitions

For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.

• Airport. The Hermiston Municipal Airport.
• Airport Elevation. The highest point of an airport's usable landing area measured in feet from mean sea level.
• Airport Hazard. Any man-made structure or object of natural growth located on or in the vicinity of the airport, or any use of land near an airport which obstructs the airspace required for the flight of aircraft in landing or takeoff at an airport or is otherwise hazardous to the landing or takeoff of aircraft.
• Approach, Transitional, Horizontal, and Conical Zones. These zones apply to the area under the approach, transitional, horizontal and conical surfaces defined in FAR Part 77 and reproduced in 151.15 through 151.21 of this chapter.
• Clear Zone. A fan-shaped area which can extend up to one-half mile from the ends of airport runways. Clear Zones retain the same height restrictions as the approach zone but because of the high incidence of air crashes in this area, land use controls are more stringent.
• Height. For the purpose of determining the height limits in all zones set forth in this chapter and shown on the zoning map, the datum shall be mean sea level elevation unless otherwise specified.
• Nonconforming Use. Any pre-existing structure, tree or use of land which is inconsistent with the provisions of this chapter or an amendment thereto.
• Non-Precision Instrument Runway. A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance or utilizing 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 a FAA planning document or military service's military airport planning document.
• Person. An individual, firm, partnership, corporation, company, association, joint stock association or governmental entity. Person includes a trustee, receiver, assignee or similar representative of any of them.
• Primary Surface:

(1) A surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the Primary Surface extends 200 feet beyond each end of that runway.

(2) The width of the Primary Surface of a runway will be 500 feet, which is that width prescribed in Part 77 of the Federal Aviation Regulations (FAR) for the most precise approach existing or planned for either end of that runway.

(3) The elevation of any point on the Primary Surface is the same as the elevation of the nearest point on the runway centerline.

• Runway. A defined area on an airport prepared for landing and takeoff of aircraft along its length.
• Structure. An object constructed or installed by man including but not limited to buildings, towers, smokestacks, earth formation and overhead transmission lines.
• Tree. Any object of natural growth.
• Utility Runway. A runway that is constructed for and intended to be used by propeller-driven aircraft of 12,500 pounds maximum gross weight and less.

§151.03 Use Restrictions

Not withstanding any other provisions of this chapter, no use may be made of land or water within any zone established by this chapter in such a manner as to:

(A) Create electrical interference with navigational signals or radio communication between the airport and aircraft;

(B) Make it difficult for pilots to distinguish between airport lights and others;

(C) Result in glare in the eyes of pilots using the airport;

(D) Impair visibility in the vicinity of the airport; or

(E) Otherwise in any way create a hazard or endanger the landing, takeoff or maneuvering of aircraft intending to use the airport.
