Staff Report 
Zoning Ordinance Text Amendment 
Z-TA-5-18-2
March 9, 2022 
Application No. Z-TA-5-18-2: Amend Section 653 of the Zoning Ordinance to modify 
the boundaries of the Desert Character Overlay Districts. 
Staff Recommendation: Staff recommends approval of Z-TA-5-18-2 as shown in 
Exhibit A. 
Purpose 
The intent of this text amendment is to revise the applicability area and associated text 
for the Desert Maintenance Overlay of the Desert Character Overlay Districts to align 
with transportation corridor updates since the adoption of the overlay district. 
The Desert Maintenance 
Overlay District contains use 
standards and district 
regulations that are contained in 
two subdistricts, Sub-District A 
and Sub-District B.  Sub-District 
A applies to land approximately 
one mile in each direction from 
Cave Creek Wash, from 
Carefree Highway on the north 
to the Dynamite Road alignment 
on the south.  Sub-District B 
applies to land east of Sub-
District A and generally extends 
to Cave Creek Road.  The 
current boundaries of the 
subdistricts are shown to the left, 
in pink (Sub-District A) and blue 
(Sub-District B).

The applicant’s proposed 
modification would modify the 
boundaries of both Sub-District A 
and Sub-District B.  Sub-District A 
standards are proposed to be 
removed from the property south 
of Sonoran Desert Drive and west 
of Cave Creek Wash.  Land south 
of Sonoran Desert Drive and east 
of Cave Creek Wash, currently in 
Sub-District A, would become a 
part of Sub-District B.  The area 
impacted by this proposed 
modification is shown to the left. 
Staff is recommending a smaller 
modification that would only 
remove Sub-District A standards 
from an approximately 155.06-acre 
portion of the original request as 
depicted on the left. 
Minor text updates to the overlay 
are also proposed to provide 
consistency with the geographic 
modifications of the subdistrict 
areas. 
There are three additional 
concurrent requests.  Rezoning 
Case No. Z-75-18-2 is a 
companion rezoning case to Z-TA-
5-18-2 and would modify the 
boundary of the Desert Character 
Overlay District on the city’s 
Zoning Map for 155.06 acres.  
General Plan Amendment Case 
No. GPA-DSTV-1-18-2 and 
Rezoning Case No. Z-62-18-2 
encompass the Verdin site (488 
acres).   General Plan Amendment

Z-62-18-2 proposes to rezone the property to a Planned Unit Development district. 
 
Background: Desert Character Overlay Districts 
The Desert Character Overlay Districts, Section 653 of the Zoning Ordinance, was 
established in 2001 via Text Amendment Case No. Z-TA-3-99 with a general purpose to 
implement the North Land Use Plan.  The intent of the overlay was to establish three 
character districts; Desert Maintenance, Rural Desert and Suburban Desert, to define 
the nature of development while maintaining undisturbed areas and to provide guidance 
for new development.  Standards for the Desert Maintenance Overlay District were 
included in the original text amendment.  Standards for the Rural Desert and Suburban 
Desert Overlay Districts have not been established. 
The overlay district contains distinct permitted uses and district standards for Sub-
Districts A and B in addition to design guidelines applicable to both subdistricts.  Single-
family residential uses are permitted in both subdistricts, with attached dwelling units 
only permitted in Sub-District B.  Select commercial uses are permitted in Sub-District 
B, subject to obtaining a Special Permit. 
District standards for the subdistricts include provisions designed to address lot size, 
building envelope, height, setbacks, access, native landscaping and treatment of 
washes.  Design guidelines contain additional guidance on site disturbance, native plant 
preservation, building and wall design, and access to preserve areas, among others. 
 
Background: Peripheral Areas C and D and North Land Use Plans 
In 1987, Phoenix City Council adopted the Peripheral Areas C and D Plan as an 
amendment to the General Plan.  The intent of the Peripheral Areas C and D Plan was 
to serve as a guide for future land use and development in the planning area, which 
consisted of approximately 111 square miles of largely undeveloped land north of the 
Central Arizona Project canal in North Phoenix.  Within the Implementation Program 
section of the Plan, further refinement of the general character elements was suggested 
prior to any formal ordinance adoption.   
 
The North Land Use Plan was adopted in 1996 to further the existing policies of the 
Peripheral Areas C and D Plan.  The Plan divided the planning area into three character 
areas, Desert Preserve, Rural Desert and Suburban Residential, and suggested that 
overlay districts be developed to provide clear development standards in line with 
community desires.  The Desert Preserve character area aligns with the area included 
in the Desert Maintenance Overlay of the Desert Character Overlay Districts.

Background: Verdin Planned Unit Development (PUD) Proposal 
The Verdin PUD (Companion Rezoning Case No. Z-62-18-2) intregrates a number of 
design considerations based on Desert Maintenane Character District standards.  
These include a sensitive transition from open space to developed areas, conservation 
of washes and wildlife habitats, and use of native plants. 
 
In addition to the considerations based on overlay standards, the Planned Unit 
Development includes enhanced standards for increased open space, connectivity to 
adjacent preserve areas, a public trail and heightened landscape standards developed 
in concert with the National Wildlife Federation.   
 
Because these standards do not apply to property outside of the Verdin PUD request 
area, staff is recommending a smaller modification to the applicability area proposed by 
the applicant. 
 
Background: Northeast Outer Loop and Sonoran Desert Drive 
The Peripheral Areas C and D Plan included discussion of a proposed Northeast Outer 
Loop.  The Northeast Outer Loop was a planned limited access extension of the 
Northwest Loop from Interstate 17, north of the Union Hills and Cave Buttes recreation 
areas, connecting to Dynamite Boulevard and traversing east toward the city of  
North Land Use Plan Character Areas, Source: City of Phoenix

Scottsdale.  Proposed land uses for Area D (north of Jomax Road) were contemplated 
based on proposed transportation infrastructure, with a Village Core planned for the 
northwest corner of Cave Creek Road and the Northeast Outer Loop / Dynamite Road 
alignment.   
 
By the North Land Use Plan’s adoption, plans for the Northeast Outer Loop had ceased.  
As a result, the planned Core at Cave Creek and Dynamite Roads was reduced in size 
and geared to function as a community service area instead of an employment hub.  
Reduction in the planned commercial area at this location contributed to the inclusion of 
the area west of Cave Creek Road into the Desert Preserve character area identified in 
the plan.  While no longer planned as a limited access roadway, Dynamite Road was 
utilized as a dividing line between a planned preservation buffer for the Cave Creek 
Wash to the north and a more dense residental area adjcent to the Cave Buttes 
Recreational area to the south.        
 
While an east-west connection between Interstate 17 and northeast Phoenix has been 
planned since 1987, public involvment efforts to refine the alignment and type of 
roadway commenced in 2002.  The final aligment for Sonoran Parkway, adopted by 
Phoenix City Council in 2006 as a result of the recommendation by the East Sonoran 
Parkway Alignment Committee, was carefully designed to minimize the impact of the 
roadway on the future mountain preserve area and intended to serve as a buffer 
between the preserve and adjacent development.  Construction of Sonoran Boulevard, 
now known as the northern leg of Sonoran Desert Drive, began in 2010 and was 
completed in 2013. 
 
Staff Analysis 
The boundary of the Desert Maintenance Overlay of the Desert Character Overlay 
Districts was derived from the Desert Preserve character area outlined in the North 
Land Use Plan.  This preservation area distinguished between the planned preserve 
area north of the then Dynamite Road alignment and the area adjacent to the Cave 
Peripheral Areas C and D Plan Land Use and Circulation, Source: City of Phoenix

Buttes Recreational area, which was slated for additional residential development.  
Subsequent to the approval of the Desert Character Overlay Districts, the roadway 
connecting Interstate 17 to Cave Creek Road was further evaluated and realigned as 
the currently constructed Sonoran Desert Drive.   
 
In addition, the companion Verdin PUD request contains development standards and 
design guidelines that are intended to provide consistency with Desert Maintenance 
Overlay standards and the general intent of the Desert Character Overlay Districts.  
These standards collectively ensure appropriate development within the undisturbed 
desert context. 
 
Due to the shift in the transportation corridor from the inception of the Desert Character 
Overlay Districts in addition to the enhanced standards contained in the Verdin PUD, 
the staff recommended modification to the Sub-District boundaries and associated 
ordinance language is warranted.   
 
Conclusion 
Staff recommends approval of Z-TA-5-18-2 to amend the applicability area and 
associated text for the Desert Maintenance Overlay of the Desert Character Overlay 
Districts as shown in Exhibit A of the staff report.

EXHIBIT A 
Text Amendment Z-TA-5-18-2:  
Modification of Boundaries of the Desert Character Overlay Districts 
 
Proposed Language: 
 
Amend Chapter 6, Section 653.A. (General Purpose of Desert Character Overlay 
Districts) to replace Figure A and read as follows: 
A. 
General Purpose of Desert Character Overlay Districts. The purpose of the 
Desert Character Overlay Districts is to implement the north land use plan, to 
define the nature of development while maintaining undisturbed areas, and to 
provide guidance for new development to occur within the context of the fragile 
undisturbed desert. The Desert Maintenance, Rural Desert and Suburban Desert 
Overlay Districts are designed in response to existing undisturbed conditions and 
pressures placed on them by increased development. The key to successful 
development within the three districts, which maintain interconnected undisturbed 
desert and washes, lies in analysis of individual subdivision sites before laying out 
the design of streets and lots. 
The Desert Maintenance Overlay District is divided into Subdistricts A and B,. as 
illustrated on Figure A. in order to address specific requirements of this area. 
Subdistrict A includes approximately one mile on both sides of the Cave Creek 
Wash and includes the area along the wash, that is not part of any Parks, 
Recreation and Library Department managed open space, such as the a Sonoran 
Preserve. With the many washes to be maintained in an undisturbed condition 
crossing this area, Subdistrict A is intended to provide a transition from the 
preserve to areas with greater density. A very low density, scale and intensity of 
residential development characterize this area. The Desert Maintenance Overlay 
Subdistrict A is the least intensive with regards to density allowed and the most 
restrictive in order to maintain the fragile undisturbed areas and the wildlife corridor 
along the Cave Creek Wash. Subdistrict B is characterized by low 
density development which may be sited in clusters along with provision for an 
area to allow access to the Cave Buttes Recreational Area. Through clustering of 
development in this area the ability to maintain large connected undisturbed areas 
and washes becomes possible.

Figure A: Desert Maintenance Character DistrictS

Amend Chapter 6, Section 653.B.2. (Desert Maintenance Overlay (Sub-Districts A 
and B), Applicability) to read as follows: 
 
2. 
Applicability. The Desert Maintenance Overlay District applies to all land 
within the area as depicted on the Desert Character District Map (Figure A). 
More specifically, the Desert Maintenance Overlay Sub-District A applies to 
all land within the area bounded by Carefree Highway on the north, the 
Dynamite Boulevard alignment on the south, a line running parallel to the 
Cave Creek Wash connecting the 24th Street alignment at Carefree 
Highway to the 16th Street alignment at the Dynamite Boulevard alignment 
along the west, and the west boundary of Dove Valley Ranch extending 
south along the Black Mountain Parkway to Ashler Hills Drive and then

running parallel to the Cave Creek Wash to the 32nd Street alignment at the 
Dynamite Boulevard alignment along the east. 
The Desert Maintenance Overlay Sub-District B applies to all land within the 
area bounded by Sub-District A on the north, the Cave Buttes Recreation 
Area along the south and west, and Cave Creek Road (excluding the 
commercially designated parcel at the northwest corner of Cave Creek Road 
and Dynamite Boulevard) together with the south and west boundary of the 
Tatum Ranch Planned Community District (west of Cave Creek Road) and 
Black Mountain Parkway along the east. 
A site plan approved in accordance with Section 507 of the Zoning 
Ordinance is required for all development, plus adherence to the design 
guidelines and standards detailed below and in Section 507 Tab A of the 
Zoning Ordinance.
