5.6.11.    FOR TIA AND DMAFB ENVIRONS
   No , use of land, or tree may exceed the height limitations by the within the Environs (AEZ). Refer to official maps established. Certain uses are prohibited from these districts as noted below and as determined by the Federal Aviation Administration (FAA).
   A.   The are identified on the Environs (AEZ) Maps and are established as follows:
      1.   Tucson International
      The height limits around Tucson International are based on distances away from the established ends of runways. The mean sea level (MSL) elevations of the established ends of runways are as follows:
         a.   NE end of runway 21 is 2,567 feet MSL;
         b.   SW end of runway 3 is 2,561 feet MSL;
         c.   NW end of runway 11L is 2,575 feet MSL;
         d.   SE end of runway 29R is 2,641 feet MSL;
         e.   NW end of runway 11R is 2,583 feet MSL; and,
         f.   SE end of runway 29L is 2,660 feet MSL.
      2.   Davis-Monthan Air Force Base
      The height limits around Davis-Monthan Air Force Base are based on distances away from the established ends of runways and also on a conical or inclined surface extending outward and upward from the established runway elevation at a ratio of 60:1. The established ends of runway MSL elevations are as follows:
         a.   NW end of the NW/SE runway is 2,590 MSL; and,
         b.   SE end of the NW/SE runway is 2,705 MSL.
   B.   Height Measurement
   The height of a , , or tree is measured from the MSL elevation at the end of the runway to a point specified in Section 6.4.4, Height, or to the highest point of a tree. (See Figure 5.6-A.)

   C.   Conflicts in Heights
   Where two or more height restrictions are placed on a , the more restrictive height limit prevails. Section 6.4.4.C, Exceptions to Height, do not apply in the AEZ.
   D.   Prohibited Uses
    as defined in Section 11.4.2 are prohibited within the boundaries of the .
   E.   Variances
   Variances from the provisions of Section 5.6.11 are allowed as set forth in accordance with A.R.S. Title 28.
