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 
hazards should be accomplished, to the extent legally possible, by the

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

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-

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

more restrictive limitation shall prevail. 

SECTION 10. 5 : USE RESTRICTIONS 

(1) GENERAL - Notwithstanding any other provisions in these 
zoning regulations, no use may be made of land within any 
zone in such a manner as to create electrical or electronic 
interference with radio or radar communication between the 
airport and aircraft; or to the installation and use of flashing 
or illuminated advertising or business signs, billboards, or 
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 
smoke that would interfere with the health and safety of flyers 
and the public in the use of the airport, or which would other-
