AS FOLLOWS:
SECTION I TITLE. This section shall be known as the Kalispell City Airport (KCA) Affected
Area Ordinance.
SECTION 11 PURPOSE AND INTENT. The purpose of this ordinance is to provide both
airspace protection and land use compatibility with airport operations at the
Kalispell City Airport. This ordinance, through establishment of airport zones
and corresponding regulations, provides for independent review of development
proposals in order to promote the public interest in safety, health, and general
welfare in the Flathead County. Therefore, the City of Kalispell and Flathead
County deems it necessary to regulate uses of land located within or near the
traffic patterns of the airport through regulation of height of structures and objects
of natural growth, and through regulation of land uses within noise impacted areas
and runway protection zones. There is hereby adopted and established the official
airport affected area ordinance pursuant to the authority conferred on the City of
Kalispell and Flathead County, Montana, consistent with Title 67, Montana Code
Annotated.
SECTION 111. DEFINITIONS. For the purposes of this ordinance, the following definitions are
applicable:

The boundaries of these zones shall be established by this ordinance and included
in the official City/County zoning maps. All development applications for land
within these zones of influence shall comply with this ordinance, as well as
complying with applicable underlying zoning district requirements. Where a zone
overlays a portion of a property, only that portion within the zone shall be
affected by the zone regulations.
A. Airport Airspace Zones, Airport Land Use Zones, and Regulations
1. Establishment
a. Airport Airspace Zones — See Sheet B
(1) Intent. These zones are intended to prevent the creation or establishment of
airport hazards by regulating and restricting the height of structures and objects of
natural growth in the vicinity of KCA.
(2) Zones. Certain zones are established which include all of the land lying within
the primary zones, horizontal zone, conical zone, precision instrument approach
zones, nonprecision instrument (NPI) approach zones, visual approach zones,
transition zones and critical area. Where both an existing and future threshold are
planned for a runway, the approach zones will consists of the area enclosed by
trapezoids for each threshold plus the lines connecting corresponding outboard
corners of the two trapezoids. Such areas and zones are shown on attached Sheet
B, Airport Airspace Zones for the airport, consisting of one sheet prepared by the
City of Kalispell, a copy of which is made a part hereof by reference. The various
zones are defined and described as follows:
(a) Primary Zones. Primary zones are hereby established as the area extending
equidistantly on either side of each runway centerline with total width:
i) For utility NPI, visual and NPI (>3/4 mile approach visibility
minimums) runways, 500 feet.
For the length of such runway plus 200 feet on each end. (Except turf runways
where the length equals the length of the runway,)
(b) Horizontal Zone. A horizontal zone is hereby established as the area within
a perimeter established by swinging arcs from points 200 feet beyond the existing
or planned ends of the runways on the extended runway centerline, then
connecting the adjacent arcs by lines tangent to those arcs. When an arc is
encompassed by tangents connecting two adjacent arcs, the arc encompassed must
be disregarded in delineating the perimeter of the horizontal surface. The radius of
each arc is:
i) For nonprecision instrument runways, 10,000 feet.
The horizontal zone does not include the primary, approach, and transition zones.
ORDINANCE NO. 1573 Page 3 of I?]
200G125 D9U40
(c) Conical Zone. A conical zone is hereby established as the area that
commences at the periphery of the horizontal zone and extends outward there
from a distance of 4000 feet. The conical zone does not include the approach and
transition zones.
(d) Nonprecision Instrument Approach Zones (less than or equal to 3/4 mile
approach visibility minimums). A nonprecision instrument (NPI) approach zone
is established at each end of nonprecision instrument (NPI) runways. Each NPI
approach zone shall have a width of 1000 feet at a distance of 200 feet beyond
each end of the runway, widening thereafter uniformly to a width of 4000 feet at a
distance of 10,200 feet beyond each end of the runway with its centerline being
the continuation of the centerline of the runway. A NPI runway designation, with
less than 3/4mile approach visibility minimums, may ultimately be established for
KCA Runway 13/31.
(e) Visual Approach Zones. A visual approach zone is established at each end of
the visual runways. Each visual approach zone shall have a width of 500 feet at a
distance of 200 feet beyond each end of the runway, widening thereafter
uniformly to a width of 1500 feet at a distance of 5200 feet beyond each end of
the runway with its center line being the continuation of the center line of the
runway. At KCA, Runway 13/31 is designated as a visual runway.
(f) Transition Zones. Transition zones are hereby established adjacent to each
approach zone and symmetrically located on each side of primary zones having
variable widths as shown on Sheet B, Airport Airspace Zones.
(g) Airport Critical Area. An area encompassing the primary zone, approach
zones and transition zones along an elevation line that is fifty feet above the
airport elevation. Airport Critical Area is based on ultimate airport size and
approach zones.
(3) Height Restrictions
(a) Height Limitations. Except as otherwise provided in this ordinance, no
structure or tree shall be erected, altered, allowed to grow, or maintained in any
zone created by this ordinance to a height in excess of the height limitation
established for such zone. Such height limitations are established for each of the
zones as follows:
i) Primary Zones.
a) Objects greater than 3 inches above grade shall be allowed only when
constructed on low impact resistant supports with the frangible point no higher
than 3 inches above grade.
b) Objects that need to be located in this area because of their function shall be
constructed at the lowest practical height.
ii) Horizontal Zone. 150 feet above the airport elevation.
ORDINANCE NO. 1573 Page 4 of 12
2096125 Dq 040
iii) Conical Zone. 150 feet above the airport elevation plus I foot in height for
each 20 feet of horizontal distance measured from and normal to the periphery of
the horizontal zone.
iv) Nonprecision Instrument Approach Zones. For each runway end, the
elevation of the threshold centerline plus I foot in height for each 34 feet
measured perpendicularly from the end of the primary zone, extending 10,000
feet.
v) Visual Approach Zones. For each runway end, the elevation of the threshold
centerline plus I foot in height for each 20 feet measured perpendicularly from
the end of the primary zone, extending 5,000 feet.
v i) Transition Zones. Begin at an elevation equal to the elevation of the nearest
point on the runway centerline, and extend outward and upward at right angles to
the runway centerline or extended runway centerline, increasing I foot in height
for each 7 feet from the sides of the primary zone and from the sides of all
approach zones.
vii) Airport Critical Area. The area as called out on the attached Sheet B, Airport
Airspace Zones, consisting of a 50-foot elevation line, above the airport elevation,
on all approach and transition zones.
(b) Conflicting Regulations. When an area is covered by more than one height
limitation, the more restrictive shall prevail.
(c) Minimum Review Height. Nothing in this ordinance shall be construed as
prohibiting the growth, construction or maintenance of any tree or structure to a
height:
i) equal to or below the airport elevation.
ii) up to fifty (50) feet above the surface of the land except the area delineated
on Sheet B. Airport Airspace Zones as "Airport Critical Area."
b. Airport Land Use Zones — See Sheets C
(1) Intent. These Zones are intended to overlay any other zoning districts and regulations
comprising or pertaining to areas to which it is applicable, so as to prevent undue
negative interaction between aviation activities associated with the Airport and the
surrounding community. It is intended to protect the lives and property of users of the
airport and of occupants of land in its vicinity by restricting "places of public assembly"
within these zones. These zones are intended to preserve the utility of the airport and the
public investment therein.
(2) Zones. Development zones are hereby established within the Airport Land Use

200Si25 UCIU'+()
centerline. Where both an existing and future threshold are planned for a runway,
the runway protection zone will consist of the area enclosed by trapezoids for
each planned threshold plus the lines connecting corresponding outboard corners
of the two trapezoids. Runway Protection Zones are sized based on aircraft
expected to be served and approach visibility minimums for the ultimate
conditions.
i) Visual and Not Lower Than I mile approach visibility minimums (Approach
Aircraft A & B Only). A runway protection zone is established at each end of
the runways. Each runway shall have protection zones that have a width of
500 feet at a distance of 200 feet beyond the runway threshold, widening
thereafter uniformly to a width of 700 feet at a distance of 1,200 feet beyond
the runway threshold, with its center line being the continuation of the
centerline of the runway, for all other than utility runways. Runway 13/31 is
planned to have a visual approach with not less than one mile visibility.
