SUMMARY
PROJECT DESCRIPTION:
Rob Gubser of Colliers Engineering & Design, on behalf of multiple property owners, is requesting
approval of a Major Amendment to approximately 1,948.2 acres within and adjacent to the Westpark
Community Master Plan (CMP). The request would expand the Westpark CMP boundary and modify the
CMP land use plan, development standards, design requirements, and related exhibits.
The proposed amendment area consists of approximately 274.8 acres currently located within the
Westpark CMP, approximately 741 acres currently located within the Silver Rock CMP, approximately
807 acres formerly located within the Westwind CMP, and approximately 125.4 acres not currently
governed by a CMP. The acreage not currently governed by a CMP includes approximately 76 acres
located north of the northeast corner of Lower Buckeye Road and Wilson Avenue and approximately
49.4 acres located south of the southwest corner of Lower Buckeye Road and 269th Avenue. Concurrent
actions associated with this request include a CMP Amendment to the Silver Rock CMP, annexation of
the 49.4-acre property south of Lower Buckeye Road, and a General Plan Amendment affecting the
125.4 acres not currently located within a CMP.
While the proposed amendment affects approximately 1,948.2 acres within and adjacent to the Westpark
CMP, it does not modify the remaining portions of Westpark not included within the amendment area.
Existing developed residential neighborhoods, schools, parks, and other community amenities located
east of SR-85 will continue to be governed by the land use plan, development standards, design
requirements, and other provisions currently in effect. As a result, the proposed amendment primarily
affects undeveloped land and does not directly impact existing residents or previously approved
development within Westpark.

A primary component of the request is modification of the CMP land use plan west of SR-85 to expand
opportunities for commercial, business park, and light industrial development. The proposed land use
framework is intended to create a large, cohesive employment area capable of accommodating a variety
of employment-generating uses while capitalizing on the site's proximity to Interstate 10, Buckeye
Airport, planned utility infrastructure, and other regional transportation facilities. Commercial and
Business Park land uses are generally concentrated nearest Interstate 10 and other prominent corridors,
creating opportunities for office, research, technology, data centers and other high-technology uses, and
campus-style development while providing an appropriate transition to larger-scale light industrial uses
located farther south within the planning area.
While the primary focus of the amendment is expansion of employment-oriented development
opportunities west of SR-85, the request also includes limited revisions to the land use plan east of SR-
85. These revisions include redesignation of certain areas from Commercial and Medium Density
Residential to High Density Residential (HDR). The proposed HDR areas are generally located adjacent
to SR-85 and are intended to provide an appropriate transition between existing and planned single-
family residential neighborhoods and the SR-85 corridor while expanding housing choice within the
Westpark community.
In addition to the proposed land use modifications, the amendment incorporates several enhancements
intended to improve the overall character and functionality of the planning area. These include enhanced
landscape setbacks and streetscape treatments along Lower Buckeye Road and Palo Verde Road that
exceed typical Development Code requirements, expansion of the trail network consistent with the City's
adopted Parks and Recreation Master Plan, minor modifications to roadway alignments, and limited
updates to development standards and design requirements.
The purpose of the request is to consolidate multiple planning areas under a single CMP framework,
allowing land uses, infrastructure, circulation systems, open space, trails, and development standards to
be planned comprehensively across a larger and more cohesive area. The proposed amendment
represents a continuation of the City's evolving vision for the portion of the SR-85 corridor within the
Westpark area as a major employment center while preserving established residential neighborhoods
and development expectations within existing developed portions of the community.
Please refer to the attached staff report and exhibits for additional information and analysis. 
BENEFITS:
The proposed amendment advances the City's vision for the SR-85 corridor as a major employment
center by creating a unified planning framework for nearly 2,000 acres of land. The request expands
opportunities for high-quality employment development, improves the City's ability to attract large-scale
employers requiring substantial contiguous acreage, and incorporates enhanced streetscape and trail
improvements that will contribute to the long-term character and functionality of the area.
Items related to a project or facility location must include an attached vicinity map for Council
Review.
