available for the landing, taking off and maneuvering of aircraft, thus
tending to destroy or impair the utility of Chicago-O'Hare International
Airport and the public investment therein. Accordingly, it is declared:
(1) that the creation or establishment of an airport hazard is a public
nuisance and an injury to the region served by Chicago-O'Hare Inter-
national Airport; (2) that it is necessary in the interest of the public
health, public safety and general welfare that the creation or establishment
of airport hazards be prevented, and; (3) that the prevention of these

In order to carry out the provisions of these zoning regulations,
there are hereby created and established certain zones which include
-5-
all of the land lying within the Instrument /pproach Zones, Non-Instrument
Approach Zones, Transition Zones, Horizontal Zones and Conical Zones.
Such areas and zones are shown on the Chicago-O'Hare International
Airport Approach Plan and Zoning Map consisting of one (1) sheet,
prepared by the Department of Aeronautics, and dated December 16th,
1964 (Revision 1 to O'Hare Field Airport Approach Plan) which is attached
to these zoning regulations and made a part thereof, and referred to
hereinafter as the zoning map. The various zones are hereby established
and defined as follows:
(1) INSTRUMENT APPROACH ZONE - an instrument approach
zone is hereby established at each end of each instrument
runway for instrument landings and take-offs. The instrument
approach zones shall have a width of 1000 feet at a point 200
feet from the end of the runway widening thereafter uniformly
to a width of 16, 000 feet at a distance of 50, 200 feet from the
end of the runway, its centerline being the continuation of the
centerline of the runway.
(2) NON-INSTRUMENT APPROACH ZONE - a non-instrument
approach zone is hereby established at each end of each
non-instrument runway for non-instrument landings and take-offs.
The non-instrument approach zone shall have a width of 1000
feet at a point 200 feet from the end of the runway widening
thereafter uniformly to a width of 4000 feet at a distance of
10, 200 feet from the end of the runway, its centerline being
-6-
the continuation of the centerline of the runway.
(3) TRANSITION ZONES - transition zones are hereby established
adjacent to each instrument and non-instrument runway and
approach zone as indicated on the zoning map. Transition zones
located normal to and at the elevation of the centerline of
instrument and non-instrument runways, have variable widths
as shown on the zoning map. Transition zones extend outward
from a line 500 feet normal to and at the elevation of the center-
line of the non-instrument runway, for the length of such runway
plus 200 feet on each end; and 500 feet normal to and at the
elevation of the centerline of the instrument runway, for the
length of such runway plus ZOO feet on each end, and are parallel
and level with such runway centerlines. The transition zones
along such runways slope upward and outward one (1) foot
vertically for each seven (7) feet horizontally to the point
where they intersect the surface of the inner horizontal
zone. Further, transition zones are established adjacent to
both instrument and non-instrument approach zones, having
variable widths, as shown on the zoning map. Such transition
zones flare symmetrically with either side of the runway approach
zones from the base of such zones and slope upward and outward
at the rate of one (1) foot vertically for each seven (7) foot
horizontally to the points where they intersect the surface of
the inner horizontal zone. . -Additionally, transition zones
-7-
are established adjacent to each instrument approach zone where
it projects through and beyond the limits of the outer horizontal
zone, extending a distance of 5000 feet measured horizontally
from the edge of the instrument approach zones at right angles
to the continuation of the centerline of the runway.
(4) INNER HORIZONTAL ZONE - an inner horizontal zone is
hereby established as the area within a circle with its center
at the Airport Reference Point and having a radius of 20, 200
feet.
(5) CONICAL ZONE - a conical zone is hereby established as
the area that commences at the periphery of the inner
horizontal zone and extends outward therefrom a distance of
8000 feet.
(6) OUTER HORIZONTAL ZONE - an outer horizontal zone is
hereby established as the area that commences at the periphery
of the conical zone and extends outward therefrom a distance
of 6000 feet.
SECTION 10. 4: HEIGHT LIMITATIONS
Except as otherwise provided in these zoning regulations, no
structure or tree shall be erected, altered, allowed to grow, or
maintained in any zone created by these zoning regulations to a height
in excess of the height limit herein established for such zone. Such
height limitations are computed from the established airport elevation
-8-

for each sixty (60) feet in horizontal distance beginning
at a point ZOO feet from the end of the instrument runway and
extending to the distance of 10, 200 feet from the end of the
runway; thence one (1) foot in height for each fifty (50) feet
in horizontal distance to a point 50, 200 feet from the end of
the runway.
(2) NON-INSTRUMENT APPROACH ZONE - One (1) foot in height
for each fifty (50) feet in horizontal distance beginning at a
point 200 feet from the end of the non-instrument runway and
extending to a point 10, 200 feet from the end of the runway.
(3) TRANSITION ZONES - One (1) foot in height for each seven (7)
feet in horizontal distance beginning at a point 500 feet normal
to and at the elevation of the centerline of non-instrument
runways, extending 200 feet beyond each end thereof and 500
feet normal to and at the elevation of the centerline of the
instrument runway, extending 200 feet beyond each end
thereof, extending upward to a maximum height of 150 feet
above the established airport elevation which is + 237. 1 feet
above city datum. In addition to the foregoing, there are
established height limits of one (1) foot vertical height for
each seven (7) feet horizontal distance measured from the edges
-9-
of all approach zones and extending upward and outward to
the points where they intersect the inner horizontal surface.
Further, where the instrument approach surface projects
through and beyond the outer horizontal zone, a height limit
at the rate of one (1) additional foot for each seven (7) feet
of horizontal distance shall be maintained beginning at the
edge of the instrument approach zone and extending a distance
of 5000 feet from the edge of the instrument approach zone
measured normal to the continuation of the centerline of the
runway extended.
(4) INNER HORIZONTAL ZONE - Thirty-five (35) feet above the
established airport elevation which is + 122. 1 feet above city
datum, measured at the periphery of Chicago-O'Hare Inter-
national Airport, thence extending upward and outward at
the rate of one (1) additional foot in height for each sixty (60)
feet in horizontal distance to a height of one -hundred-fifty
(150) feet above the established airport elevation which is
+ 237. 1 feet above city datum, which height is then constant
to the outer end of the inner horizontal zone.
(5) CONICAL ZONE - One (1) foot in height for each forty (40)
feet of horizontal distance beginning at the periphery of the
inner horizintal zone and at the elevation established therein,
extending to a height of 350 feet above the established airport

any other type of illuminated structure which would be hazardous
for flyers because of the difficulty in distinguishing between
airport lights and others, or which result in glare in the eyes
of flyers using the airport, thereby impairing visibility in the
vicinity of the airport or endangering the landing, taking -off,
or maneuvering of aircraft; or which would emit or distharge
