A. INTRODUCTION 
Costco Wholesale is the developer and operator of the proposed Costco Chandler Business Center which 
consists of approximately 170,500 sf of retail development on +/-18.65 gross acres located at the southwest 
corner of Pecos Road and Alma School Road in Chandler, Arizona. As shown in Exhibit 1, Site Context, 
the project site is made up of one existing parcel APN: 303-26-003P. The property is currently being utilized 
for agricultural uses. This request is to amend the zoning and preliminary development plan of the subject 
property from Planned Area Development (PAD) for an office park with ancillary retail and restaurant uses, 
including a Mid-Rise Overlay for building Height up to 75 feet to Planned Area Development (PAD) for the 
Costco Business Center and Fuel Center based upon the C-2 Community Commercial District. 
 
This use is appropriate for this area and site which is currently zoned for retail use and office space. With 
the proposed reduced building square footage, removal of the parking garage, and substantial landscaping, 
this use better suits the area and supports the needs of local small business as well as residents. Approval 
of this proposal will allow for a new commercial corner that will complement the existing commercial uses, 
parks, schools, residential, employment and religious uses that surround it.

B. SITE, SURROUNDING AREA, AND EXISTING ZONING 
The Site is designated on the City’s General Plan as Neighborhoods. The Neighborhood designation allows 
for a variety of non-residential uses. See Exhibit 2, Chandler General Plan.  The site is currently zoned 
PAD and designated for an Office Park with ancillary retail and restaurant uses, including a Mid-Rise 
Overlay for building Height up to 75 feet. This office park has not been developed and the Site is currently 
use for agricultural purposes. This request will allow for the development of the site in a manner that is less 
impactful from a peak hour traffic aspect while also serving local small business and residents through the 
Business Center and Fuel Center. The Site is bounded by multifamily use Camden Pecos Ranch 
Apartments to the west, multifamily use The Casitas at San Marcos to the north, the Banner Medical Office 
complex to the east, and Loop 202 to the south. This location also provides excellent access to the freeway. 
 
C. PROPOSED PRELIMINARY DEVELOPMENT PLAN 
1. Site Layout 
The proposed Preliminary Development Plan is designed to be mindful of the existing neighbors 
as well as provide an inviting and convenient destination for local business owners and residents. The 
proposed building is planned to be approximately 170,500 square feet and be located in the southwest 
corner of the Site. This is a significant reduction from the Office Park use previously approved that allowed 
for 400,000 square feet of office space with ancillary retail spaces as well as a four-story parking garage 
located only 20 feet from the existing multifamily use to the west. The proposed plan provides a 60-foot 
setback from the western property line to the building face. The proposed use also has a maximum height 
of 36 feet for buildings. The previously approved use had a maximum height of 75 feet. The location of the 
Fuel Center was carefully coordinated with city staff to manage queueing for the fuel dispensers. Proper 
circulation and adequate storage lengths along with the proposed signal improvements were analyzed in 
the decision of placing the Fuel Center at the southeast corner of the project. The location of the Fuel Center 
provides appropriate visibility while reducing the potential for traffic conflicts offsite. See Exhibit 3, Site 
Plan. 
2. Architecture 
The overall theme for the building is a contemporary design focused on clean, simple lines that is 
attractive and consistent with the design standards for the City of Chandler while also being recognizable 
as a Costco Business Center. See Exhibit 4, Building Elevations. The architecture features undulating 
roof heights, alternating materials and horizontal relief to break up the massing. Pedestrian elements such 
as trellis and shade structures at seating areas were incorporated to enhance the pedestrian experience. 
Variations in the neutral colors including Taupe, Sandstone, and Bronze have been utilized to match the 
desert background and are consistent and appropriate within the context of the area. See Exhibit X, Color 
& Materials Board.

3. Landscaping 
The landscaping for the project has been designed per the development requirements of the City 
to create an attractive appearance for the overall development and community. See Exhibit 5, Landscape 
Plan. The southwest corner of the intersection of South Pecos Road and West Alma School Road will have 
a 50’ landscape buffer consisting of earthen berms, a screening hedge, meandering trees and unique cacti 
and succulent species. The enhanced landscape corner treatment at South Alma School Road and West 
Pecos Road will be a palette of palms, accent shrubs and succulents, earthen berms, boulders, and rock 
creating an impactful landscape statement for the neighborhood.  The site landscape design will create 
appropriate shade and buffer areas within and along the perimeters of the site while providing an attractive 
appearance for the overall development. The site parking field and perimeter will be planted with a 
sustainable, colorful, and attractive plant palette to draw interest to and through the Site. The west property 
line adjacent to the multi-family development, Dissimilar Buffer, will be planted with screening trees at 
twenty feet (20’) on center and interspersed with dense shade trees planter at forty feet (40’) on center, 
creating a dense screen between the proposed development and the adjacent use.
