AMENDMENT NO. 3
Pyramid Peak WTP Improvements and Expansion Project
(City Project Nos. 151619 and 151620, Contract No. C-11349-3)

This Amendment No. 3 (“Amendment”) to the Professional Services Agreement
(“Agreement”) is made this day of , 2021, (“Effective Date”), by and
between the City of Glendale, an Arizona municipal corporation (“City”) and Black &
Veatch Corporation, a Delaware corporation authorized to do business in Arizona
(“Contractor”).

RECITALS

A. City and Black & Veatch Corporation (“Contractor”) previously entered into a
Professional Services Agreement for Design & Construction Services - Pyramid Peak
Water Treatment Plant Improvements & Expansion (WTP), Contract No. C-11349,
dated November 22, 2016 (“Agreement”); and

B. Based on studies developed during Phase I (C-8912), improvements were identified
for the Pyramid Peak WTP to repair and replace equipment to ensure continued
compliance with existing regulations, decrease frequency of corrective maintenance,
and improve plant resiliency (Process Improvements). Additionally, the City of
Peoria sought to expand the Pyramid Peak WIP to acquire an additional 15 million
gallons per day (MGD) treatment capacity of its Central Arizona Project (CAP)
allocation (Expansion Improvements). The 15 MGD expansion will result in an
expanded total plant treatment capacity of 54 MGD. ‘The City of Peoria's resulting
ownership capacity will be 24 MGD or 44.4% and Glendale's ownership capacity will
be 30 MGD, approximately 55.6%. These efforts are represented in Contract C-
11349 dated 11/22/2016.

C. Construction Administration Services for initial early improvements to the Pyramid
Peak WIP treatment plant were completed (service and potable water pumps,
chlorine feeders, chlorine dioxide generator etc.) and also included an allowance
from the original contract (C-11349) for an assessment of the existing 67th Avenue
transmission main (from the Pyramid Peak WTP reservoirs to Jomax Rd. These
efforts ate represented in Amendment 1 (Contract C11349-1, dated 04/10/2018) to
the Professional Services Agreement.

D, Construction Administration Services for remaining improvements to the Pyramid
Peak WTP treatment plant for process improvements and expansion efforts are
underway and are represented in Amendment 2 (Contract C11349-2, dated
06/25/2019) to the Professional Services Agreement

E. Due to discovered previously existing water filter conditions (underdrains etc.) during
the execution of remaining improvements (C11349-2), it is imperative the existing
filters at the Pyrmaid Peak WIP be rehabilitated / repaired immediately to assure
continued plant resiliency and operation. Additionally, the City desires to expand the
initial assessment length of the transmission main to also include the length of main
