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 
exercise  of  the  police  power  without  compensation.

-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,

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.

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
