Project Narrative  
(February 18, 2026) 
 
Project Description 
 
DMB Mesa Proving Grounds, LLC, a Delaware limited liability company 
(“Brookfield”) is the Master Developer of the Eastmark master planned community 
with is approximately 3,200 acres located south of Elliot Road, north of Williams 
Field Road, east of Ellsworth Road and west of Signal Butte Road (“Eastmark”). 
 
Request 
This application is a request to amend the approved Development Unit Plan 
(“DUP”) for Development Units (“DUs”) 5 and 6 south (“Amended DUP 5/6s”).  This 
area is roughly bounded on the north by Elliot Road, on the east by Signal Butte 
Road, on the south by Point Twenty-Two Boulevard and by Eastmark Parkway to 
the west as show on Exhibit A.  DUP 5/6s includes area within DU 5 and DU6. This 
Amended DUP5/6s will supersede the version approved on May 17, 2017.

Overview of Amendment to DU5/6 South DUP 
 
The purpose of the Amendment is to address the Transition Area as called out in 
the approved DUP 5/6s which is located in a small area west of Signal Butte and 
south of DU 6 North as shown on Exhibit B.  Additionally, with this amendment street 
alignments are being modified to reflect actual roadway alignments and to 
identify the location of the last phase of the Eastmark Great Park, also located 
within the former Transition Area.   
 
Exhibit B 
 
 
 
Since the DUP 5/6s was approved in 2017, the majority of the property has been 
developed with residential, commercial and employment uses.  Some of the last 
remaining parcels are in the “Transition Area” which constitutes less than 40 acres 
(including 25 acres of Great Park).  In 2017, when the DUP for 5/6s was approved, 
very little of this area was developed other than the Apple facility at Elliot and 
Signal Butte.  The Transition Area for a small area was called out because the 
development pattern to the north was not known and the City wanted to provide 
for an opportunity for further review as future development occurred in the area.. 
Since that time, the area has almost completely developed and/or has been 
planned for development; thus, appropriate consideration for compatible 
development/transition uses are now apparent.  This plan will eliminate the 
Transition Area designation and provide for appropriate Land Use Group (“LUG”) 
designations for this small area.  Additionally, this request will establish the actual 
road alignments existing or being designed/completed.   
 
Since 2017, the significant development that has occurred is consistent with the 
Eastmark CP, and the DUP 5/6s.  The employment and industrial uses in this area 
are generally set in a campus type setting, are consistent with the Vision for 
Eastmark, are consistent with the City’s Elliot Road Technology Corridor area and 
are compatible with the Mesa Gateway Airport.

To transition from the employment uses in the northern portion of Eastmark, a 
linear corridor system that extends east-west was put in place and has been 
developed.  This linear corridor was intended to and does provide a buffer and 
transition to the existing residential uses in the DUP 5/6s area and further south.  For 
example, the linear open space serves as a connecting element for the Eastmark 
Great Park and will culminate at the final phase of the Great Park located within 
the area that is a part of this amendment. This last phase of the Great Park consists 
of approximately 25 acres and provides an active open space full of amenities 
that will be a gathering point for residents.  This portion of the Great Park is 
currently under construction and will be completed in 2026.   
 
The Amended DUP 5/6s will now completely eliminate the Transition Area and 
define Land Use Groups (“LUGs”) for this area.  Specifically, proposed and 
appropriate LUGs include the District LUG, the Civic and Open Space LUGs.  With 
these LUGs are appropriate uses including active open space (coinciding with 
the last Phase of the Eastmark Great Park) and greater density/intensity of 
residential (i.e., garden apartments / multi-family) and commercial type uses.  
These types of uses are perfect transitions with the employment uses north of 
Rubidium, the commercial development along Signal Butte and the single family 
uses to the South.  The Eastmark Great Park will be completed in 2026 and 
provides a nice buffer and central community amenity.  With the addition of a 
multi-family residential development within the last parcel between the Great 
Park and the Commercial center provides a perfect and appropriate transition.

Infrastructure Plans 
 
Updates to infrastructure plans have been approved and all infrastructure in the 
DUP exists and has been completed, including completed construction of 
Eastmark Parkway and Everton Terrace north to Elliot Road, Mesquite Road, Binary 
and Rubidium Road.   
 
Summary 
 
The proposed Amendment to the DUP for DU5/6s will address a small area called 
out as Transition Area between DU 6s and DU 6N.  This Amendment will eliminate 
the Transition Area designation and provide the final LUGs for this area to guide 
the development and provide an appropriate transition between the various 
surrounding developed areas.  Additionally, the Amended plan will update 
graphics to reflect actual alignments for the roadways.
