PURPOSE: 
The Development Services and Utilities Departments are requesting approval of a Cooperative Purchasing 
Agreement between the City of Tolleson and Kimley-Horn and Associates, Inc. for on-call civil engineering 
services related to the development of the City’s centralized water treatment plant. 
 
BACKGROUND: 
The Arizona Department of Administration entered into a competitively procured contract with Kimley-Horn 
and Associates, Inc. for on-call civil engineering and final engineering design services. This contract allows 
cooperative use by other public entities, including the City of Tolleson, pursuant to Section 3-5-7 of the Tolleson 
City Code. 
 
This Cooperative Purchasing Agreement provides Tolleson access to Kimley-Horn’s professional engineering 
services to support the City’s Well Site No. 9 and the broader development of a centralized water treatment 
plant, including well equipment, storage tank, booster pump station, onsite treatment, and ancillary 
infrastructure. 
 
DISCUSSION: 
The Agreement is effective through February 7, 2026, unless terminated earlier in accordance with its terms. It 
is structured as an indefinite delivery and indefinite quantity contract, meaning services will be provided on an 
as-needed basis, subject to City-issued purchase orders. 
 
The availability of Kimley-Horn’s on-call engineering expertise will assist the City in advancing critical water 
infrastructure improvements and ensuring regulatory compliance as Tolleson continues to expand and 
modernize its utility systems. 
 
BUDGET IMPACT: 
Compensation under this Agreement shall not exceed $900,000 per fiscal year.  
 
RECOMMENDATION: 
Staff recommends approval of the Cooperative Purchasing Agreement between the City of Tolleson and Kimley-
Horn and Associates, Inc. for on-call civil engineering services, and authorization for the City Manager to execute 
and deliver said Agreement.
