A.
proposing to exceed the limits of the Performance Standards established in Sections 5.6.8.A, B. and C, are processed in accordance with Section 3.4.3, Zoning Examiner Special Exception
Procedure. These applications are analyzed for: 1)
with base operations, 2) proximity to the end of the runway, 3) location in relationship to major flight tracks, and 4) compliance with the intent of the DM Joint
Study.
B. In addition to the notice required for Special Exception

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.
These standards are intended to recognize the value of Tucson’s

These standards relate to areas associated with Tucson’s public lands and preserves, including Saguaro National Park, Coronado National Forest, and Tucson Mountain Park. It is the intent of these standards to protect valuable habitat resources to the greatest extent possible.

specifically serves to:
A. Recognize the social, economic, environmental, biologic, and cultural importance of Saguaro National Park and Tucson Mountain Park to the City of Tucson;
B. Buffer Saguaro National Park and Tucson Mountain Park from the impacts of new

, and groundwater recharge through the preservation of designated washes in natural and undisturbed states; and,
E. Assist in implementing the
policies that call for the preservation of Tucson’s significant natural areas along designated watercourses where identified in adopted area and neighborhood plans.
A. Areas Mapped
that may contain
are shown on a series of maps approved by the Mayor and Council called the Environmental Resource
Overlay Maps (ERZ Maps). The ERZ Maps include all

Approval Procedure.
D. Designation, Amendment and Change of Boundaries for ERZ Washes
Designations of new areas subject to this section and changes to existing designations are processed in accordance with Section 3.5, Rezoning (Change of Zoning) Procedure. For designation of new area within the , the proposed designation shall be reviewed by the Stormwater Advisory Committee (SAC) and Stormwater Technical Advisory Committee (STAC) prior to the public hearing before the Zoning Examiner. The recommendations of the SAC and STAC are forwarded to the Zoning Examiner prior to the public hearing.
E. Approved
