As used in this chapter, unless the context otherwise requires:
"Airport"
means public-use airports including Easton State, Cle Elum
Municipal, DeVere Field and Kittitas County Airport (Bowers Field).
"Airport elevation"
means the airfield elevation in feet above mean sea level
depicted on an FAA or WSDOT-approved Airport Layout Plan (ALP), or
as published in the FAA Chart Supplement for airports without an approved
ALP. The established airport elevations for airports in Kittitas County
are as follows:
|
Kittitas County Airport (Bowers Field) at 1,763 feet above mean
sea level
|
|
Easton State Airport at 2,226 feet above mean sea level
|
|
DeVere Field at 1,800 feet above mean sea level
|
|
Cle Elum Municipal Airport at 1,945 feet above mean sea level
|
"Airport overlay zoning district"
shall include the runway protection zone, inner safety zone,
inner turning zone, outer safety zone, sideline zone, and the airport
operation zone as depicted on Map "B" - "Airport Safety Zones" and
numbered zones 1 through 6, respectively, and shall also encompass
the area identified within 14 CFR Federal Aviation Regulations (FAR)
Part 77, as amended and depicted on Map "A" - "Part 77".
"Airport surface"
means a surface longitudinally centered on the extended runway centerline, extending outward and upward from the end of the primary surface and along the same slope as the approach zone height limitation slope set forth in KCC §
17.58.050. The perimeter of the approach surface coincides with the perimeter of the approach zone.
"Conical surface"
means a surface extending outward and upward from the periphery
of the horizontal surface at a slope of 20 feet upward to one foot
outward for a horizontal distance of 4,000 feet.
"Flammable and combustible liquids"
shall be defined as the type and design of underground and
aboveground liquid storage tanks; the location and design of the fuel
dispensers and dispenser nozzles; the design and specifications for
related piping, valves and fittings; the location and classification
of electrical equipment, including emergency fuel shutdown devices;
and specifications for fuel storage and pressure-relief components,
and shall be in accordance with Article 52 (5201.3.2(#1) Motor Vehicle
Fuel - Dispensing Stations), Article 79 (Flammable and Combustible
Liquids, specifically Special Options 7904), Standard of the International
Fire Code and all applicable codes.
"Hazard to air navigation"
means 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 chapter and shown on the airport overlay zoning
district map "A", the datum shall be mean sea level elevation unless
otherwise specified.
"Larger than utility runway"
means a runway that is constructed for and intended to be
used by propeller driven aircraft of greater than 12,500 pounds maximum
gross weight and jet-powered aircraft.
"Nonconforming use"
means any preexisting structure, object of natural growth,
or use of land, which is inconsistent with the provisions of this
chapter.
Nonprecision Instrument Approach.
A nonprecision instrument approach is designed to provide
inbound electronic course alignment to aircraft approaching the airport
or a specific runway end for landing. Nonprecision instrument approaches
may be classified as “straight-in” to a specific runway
end, or “circling” to allow an aircraft to land on any
runway end on the airfield while maintaining visual contact with the
airport environment once past the missed approach point.
"Nonprecision instrument runway"
means a runway having an existing or planned non-precision
straight-in instrument approach procedure to at least one runway end.
"Obstruction"
means any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in KCC §
17.58.050.
"Person"
means an individual, firm, partnership, corporation, company,
association, joint stock association or government entity. "Person"
includes a trustee, a receiver, an assignee, or a similar representative.
Precision Instrument Approach.
A precision instrument approach is designed to provide a
defined electronic approach path with horizontal and vertical guidance,
utilizing ground based or satellite air navigation facilities. Precision
instrument approaches provides defined inbound course alignment and
vertical descent for aircraft on final approach and landing to a specific
runway end.
"Primary surface"
means 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. For military runways or 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 is defined by FAR Part 77, and is described in KCC §
17.58.040A and KCC §
17.58.040B for each runway addressed in this chapter. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.
"Runway"
means a defined area on an airport prepared for landing and
takeoff of aircraft along its length.
"Structure"
means an object, including a mobile object, constructed or
installed by man, including but without limitation, buildings, towers,
cranes, smokestacks, earth formation, and overhead transmission lines.
“Transitional surface”
means the surfaces that extend outward at a 90-degree angle
to the runway centerline and the extended runway centerline from the
sides of the primary surface and approach surface, at a slope of seven
feet horizontally for each one foot vertically, until reaching the
horizontal surface, 150 feet above airport elevation. For precision
instrument approaches, transitional surfaces also extend from the
sides of the outer portion of the approach surface that extend beyond
the limits of the conical surface. The precision approach transitional
surface extends 5,000 feet horizontally from the edge of the approach
surface at 90-degree angles to the extended runway centerline, at
a slope of seven feet horizontally for each one foot vertically.
"Tree"
means any object of natural growth.
"Utility runway"
means a runway that is constructed for and intended to be
used by propeller-driven aircraft of 12,500 pounds maximum gross weight
or less.
"Visual runway"
means a runway intended solely for the operation of aircraft
using visual approach procedures, including visual segments of circling
non-precision instrument approaches.
