Mayor Freeman conducted a roll call. 
 
1-a. 
Hear a presentation, discuss, and provide direction on Mesa City Center, including the 
redevelopment of the Post Office into Arizona State University Creative Technologies building, 
construction of a new retail Post Office, and development of the Light Walk. 
 
This presentation will be rescheduled to a future date. 
 
1-b. 
Hear a presentation, discuss, and receive an update on the current conditions of the Colorado 
River and impacts to the City of Mesa water portfolio.  
 
Water Resources Director Christopher Hassert introduced Assistant Director Jessie Heywood and 
displayed a PowerPoint presentation. (See Attachment 1) 
 
Mr. Hassert advised that the 20-year Colorado River operating guidelines established in 2007 are 
set to expire at the end of 2026, amid an ongoing, prolonged drought and discussed the water 
level challenges and negotiations with other states. He reviewed the City’s service areas and the 
water resources for each zone. He defined the term “acre-foot” as it relates to water supply, noting 
that one acre-foot is equivalent to a volume of water covering nearly the size of a football field, 
160 feet. (See Pages 2 through 4 of Attachment 1) 
 
Mr. Hassert explained that surface water for the City Zone area is treated at the Val Vista Water 
Treatment Plant, which is operated by Phoenix and jointly owned with Mesa. He stated that the 
City of Mesa (COM) has a treatment capacity of 90 million gallons per day (MGD) and access to 
about 62,000 acre-feet of water annually through Salt River Project (SRP), while current demand

Study Session 
February 12, 2026 
Page 2 
 
 
is significantly lower at 33,000–35,000 acre-feet. He noted that demand is stable due to limited 
growth in the largely built-out area, resulting in excess capacity. He emphasized that this water 
supply is independent of the Colorado River, relying instead on in-state Salt and Verde River 
systems, which are currently at about 57% capacity. (See Page 5 of Attachment 1.) 
 
In response to multiple questions from Councilmember Goforth, Mr. Hassert shared that in the 
past when SRP declared a shortage and significantly reduced supplies, the City maintained 
supply capacity above its demand within the City Zone, and the City continues to have excess 
capacity available. He explained the forecasting process that staff performs to determine the 
amount of water the City will require, and confirmed that the City does not store any unused water.  
 
Responding to a question posed by Councilmember Taylor, Mr. Hassert affirmed that Mesa only 
uses approximately 50% of its SRP on-project water, its main provider, which is sufficient to serve 
households in that region. He mentioned that although there is excess capacity in on-project 
areas, that water cannot be transferred elsewhere.  
 
Mr. Hassert discussed the Central Arizona Project (CAP) off-project water supply which has been 
developed independently, primarily from Colorado River sources. He added that the biggest share 
of Colorado River water comes from municipal and industrial (M&I), and the current demand in 
the eastern and southern zones is about 58,000 acre-feet; however, Mesa has about 61,000 acre-
feet available, slightly exceeding current demand. He indicated that future Colorado River cuts 
are expected to create challenges, making additional and backup supplies necessary. (See Page 
6 of Attachment 1) 
 
Responding to a question posed by Councilmember Duff, Mr. Hassert explained that while 
infrastructure could physically allow water to move from SRP canals to the CAP canal, on-project 
water cannot legally be transferred and the benefits must stay with the land. He noted that Mesa 
is able to transfer its share of New Conservation Space (NCS) water, since Mesa pays for NCS 
water and related projects, allowing that water to be moved to the Southeast. 
 
Mr. Hassert identified Mesa’s additional water supplies and discussed the water exchange 
process for the Gila River Indian Community (GRIC). He emphasized that the water obtained 
through the GRIC exchange is significantly cheaper, $85 per acre-foot versus $365 for standard 
CAP M&I water. (See Pages 7 and 8 of Attachment 1) 
 
Responding to a question from Councilmember Goforth, Mr. Hassert answered that the exchange 
water costs fluctuate annually based on CAP energy costs. He indicated that the pumping rate 
recently dropped from $95 to $85 per acre-foot, while standard (M&I) CAP water continues to 
increase in price.  
 
Mr. Hassert stated that CAP is the largest energy consumer in the state of Arizona.  
 
Mr. Hassert reviewed Mesa’s NCS additional water supply and the history and expansion of 
Roosevelt Dam, noting that the project was significant for Mesa, providing an additional 41,000 
acre-feet of flood storage. He emphasized that the NCS water is not limited to specific projects 
and may be used anywhere within Mesa’s service area. He indicated that Bartlett Dam, located 
on the Verde River, is undergoing construction of a new dam, creating new flood storage. He 
reported that Mesa is a stakeholder and anticipates receiving between 10,000- to 13,000-acre 
feet to help support off-project areas. (See Page 9 of Attachment 1)

In response to multiple questions from Councilmember Taylor, Mr. Hassert explicated the 
calculations of the water storage and commented that staff expect to increase the annual NCS 
supply from 12,500 to approximately 15,000 acre-feet of storage.  
 
Responding to a question posed by Mayor Freeman, Mr. Hassert replied that Mesa uses about 
88 million gallons of water per day, or approximately 98,000 acre-feet annually citywide, with 
about 58,000 acre-feet in CAP service areas. 
 
In response to a question from Councilmember Duff, Mr. Hassert reported that this year the 
reservoir levels across the West are expected to be below average. He noted, while conditions 
within the SRP system are currently holding steady, they remain below average, and Colorado 
River supplies are also projected to be below average. 
 
Councilmember Duff commented that Arizona’s water supply depends more on snowfall than 
rainfall.  
 
Councilmember Taylor shared that during a recent SRP watershed tour, hydrologists reported 
reservoirs at Bartlett Lake, Horseshoe Bend, and the Verde River were slightly above maximum 
allowance at that time due to recent rain, though conditions are expected to fluctuate. 
 
Mr. Hassert explained that Mesa’s backup groundwater source provides approximately 10,000 
acre-feet per year in the City’s 100-year Assured Water Supply. He described the two components 
of groundwater and the process for using the aquifer and how the amount for the water supply is 
determined. He stated that Mesa typically pumps about half that amount in a normal year to 
preserve groundwater as a backup supply, though pumping could increase during Colorado River 
shortages, particularly to support eastern and southern service areas. (See Page 10 of 
Attachment 1) 
 
In response to multiple questions from Councilmember Taylor, Mr. Hassert commented that 
leakage mainly comes from pipe joints and seeps back into the aquifer, and Mesa receives credit. 
He mentioned that Mesa’s leakage rate is about 5%, which is considered good since Arizona 
requires water providers to stay below 10% under the 1980 Groundwater Management Act.  
 
Responding to a question posed by Councilmember Goforth, Mr. Hassert explained how unused 
groundwater is allocated. 
 
Mr. Hassert provided an overview of Mesa’s long-term storage credits (LTSCs), noting that the 
City has over 500,000 acre-feet banked underground. He pointed out several ways to earn LTSC 
and emphasized that Mesa has approximately 10 years of LTSC to use. (See Page 11 of 
Attachment 1) 
 
In response to multiple questions from Councilmember Duff, Mr. Hassert discussed the process 
for large water users who must obtain their own LTSC rather than using the City’s supply. He 
explained that Mesa directs companies to third-party suppliers and estimates how many credits 
are required over a three-year forecast. He elaborated on the locations of water pumping and the 
credit source. He advised that many large companies are redesigning operations to use less 
water, partly because LTSCs are expensive. He described how a closed loop system operates 
more efficiently.  
 
Responding to a question from Councilmember Taylor, City Manager Scott Butler said that 
Google has begun transitioning from water cooled to air cooled facilities due to water use

Study Session

concerns from the community. He stressed that the City encourages companies to use the most 
sustainable water and energy technologies.  
 
In response to a question posed by Councilmember Heredia, Mr. Hassert stated that every city 
or town has guidelines in place through the 1980 Groundwater Management Act on how water is 
pumped and the constraints, as well as each city must maintain its own Assured Water Supply. 
He mentioned the partnerships with the Arizona Municipal Water Users Association (AMWUA), 
and the future of water use. He mentioned that all cities have groundwater challenges. 
 
Mr. Butler added that the City stays vigilant in ensuring that water supplies are protected.  
 
Responding to a question posed by Mayor Freeman, Mr. Hassert replied that the City has 557,084 
acre-feet of annually stored water credits, and when water is pumped from the ground those 
credits are extinguished. He discussed the options for recharge programs to increase their LTSC 
and exchange water. He noted that Mesa continues to build storage credits, but in years with 
severe water cuts, the City may use some of those stored credits, which are permanently reduced 
once pumped. 
 
Mr. Heywood presented historical data showing that Mesa’s water demand rose sharply in the 
1990s due to population growth and higher per-customer use, peaked around 2004, and has 
since leveled off despite continued customer growth, largely due to efficiency improvements. He 
noted that surface water sources are expected to increase in supply beginning in 2027–2028 with 
the Central Mesa Reuse Pipeline delivering a full year of reclaimed water to the GRIC. (See Page 
12 of Attachment 1) 
 
Mr. Hassert added that the water supply is ordered by cost priority, with the least expensive water 
used first (CAP exchange water with GRIC at about $85 per acre-foot), while more expensive 
sources are added afterward.  
 
In response to a question from Mayor Freeman, Mr. Hassert replied that the City pays 
approximately $70 per acre-foot for SRP water.  
 
Mr. Heywood provided an overview of a scenario involving significant Colorado River cuts and 
leased water projected to occur in 2027 that assumes a gap between projected demand and 
available surface water. He described another scenario that includes additional water sources 
where the City would be able to meet demand. (See Pages 13 and 14 of Attachment 1) 
 
Mr. Hassert clarified that within the next five years, even with an estimated 20% water cut, Mesa 
would rely very little on backup supplies. He added that since the actual cuts are still being 
negotiated, any additional reductions would further decrease available surface water, requiring 
greater use of alternative supplies. He noted that beyond 2030, current efforts, such as projects 
involving Bartlett Dam and exploring new water sources, will become critical to maintaining 
supply, emphasizing the need for long-term planning to stay ahead of potential shortages. 
 
Responding to multiple questions posed by Councilmember Taylor, Mr. Hassert cautioned that 
SRP project water must remain on designated project lands and cannot be used citywide, but 
Mesa can utilize their additional water sources funded at Roosevelt and Bartlett Dams to transfer 
its own water through the CAP canal. He added that these supplies can be used citywide, though 
they are typically directed where needed.

In response to multiple questions from Councilmember Duff, Mr. Hassert explained that future 
cuts to the CAP will create a firm limit on available Colorado River water, effectively capping how 
much cities can grow their water use. He advised that cities, including Mesa, must plan within 
these limits unless they develop alternative supplies. He added that rural areas are largely 
independent since those areas rely on separate aquifers that are not hydrologically connected to 
the City’s. 
 
Mr. Hassert reported that to prepare for potentially more severe and long-term water cuts, Mesa 
has been proactively expanding its water supply portfolio for several years. He discussed key 
efforts, including adding supply from the Bartlett Dam project, about 3,000 acre-feet annually, and 
combining it with existing NCS water stored behind Roosevelt Dam. He also highlighted the GRIC 
exchange, which currently provides about 8,000 acre-feet, but could increase to 16,000–17,000 
with the reuse pipeline. He commented that the City is exploring infrastructure improvements to 
increase reclaimed water production and maximize available Colorado River supplies. (See Page 
15 of Attachment 1) 
 
In response to multiple questions posed by Councilmember Duff, Mr. Hassert confirmed that Mesa 
is not close to reaching its capacity of the exchange, and that the exchange cannot decrease their 
limit per the contract which is secured until 2100. He answered that the COM is working with the 
City of Phoenix on the 91st Avenue Water Treatment Plant that would treat excess reclaimed 
water to drinking standards, with Phoenix using the water locally while Mesa would receive an 
equivalent supply through exchange. He noted the project is costly but may receive federal 
funding. 
 
Mr. Hassert described several strategies to expand Mesa’s water supply and efficiency. He 
summarized the key points to managing Mesa’s water resources. He indicated that the City has 
a strong and diversified water portfolio and is continuously evaluating and adjusting strategies to 
stay ahead of shortages while considering long-term feasibility and cost. He discussed the 
different levels of the water shortage plan, tools, and customer outreach. (See Pages 15 and 16 
of Attachment 1) 
 
Responding to multiple questions from Councilmember Taylor, Mr. Hassert replied that while the 
GRIC can face initial cuts to the CAP amounts, the federal government contract requires the 
government to replace those supplies, by securing storage, ultimately benefiting Mesa by 
stabilizing its exchange supply.  
 
Councilmember Taylor emphasized that Mesa has responsibly and proactively managed its water 
planning, including long-term projections for growth and its 100-year Assured Water Plan. She 
stressed that each city is accountable for its water use and infrastructure decisions, and 
suggested the importance of communicating to residents that Mesa has effectively secured the 
current water capacity and the intentions for future water, and has the right to protect its resources. 
 
Discussion ensued regarding the GRIC water exchange, investing in water infrastructure 
expansions, and the Drought Management Plan.  
 
In response to a question from Mayor Freeman, Mr. Hassert confirmed that the City is still waiting 
for its Assured Water Supply designation to be approved by the Arizona Department of Water 
Resources (ADWR).

Government Relations Manager Kathy Macdonald advised that the application has been under 
review since October 2023, but the City’s designation has been extended in the meantime. She 
noted that there are currently 118 water bills in legislature.  
 
Mayor Freeman commented on the challenges to capture excess water in past years and stressed 
the importance of having local control and not outsourcing through legislature. He indicated that 
projects, such as the Bartlett Dam and system improvements, help to better store and utilize 
water. 
 
Responding to a question from Mayor Freeman, Mr. Hassert explained that building a well costs 
approximately $6 to $7 million total; to manage costs and market fluctuations, the City is phasing 
projects and bidding wells in stages rather than all at once. He highlighted current Desert Wells 
25 and 26 projects, noting additional well fields are planned farther south with projects extending 
over the next 20 years. 
 
Councilmember Duff expressed appreciation for Mr. Hassert’s leadership and expertise, crediting 
him and his team for strengthening Mesa’s water system and leaving the City in a strong position. 
 
Mr. Butler praised Mr. Hassert and his team for building a resilient and diverse water portfolio that 
supports residents and attracts businesses. He emphasized the importance of exploring multiple 
future water sources despite challenges and costs, and thanked Mr. Hassert for his leadership.  
 
Mr. Butler announced that the new Water Resources Director will be Joseph Giudice upon Mr. 
Hassert retiring. He stated that Mr. Giudice has provided strong leadership in the Solid Waste 
Department and brings significant water-related experience from his time with the City of Phoenix 
prior to joining the COM.  
 
Councilmember Adams thanked Mr. Hassert and suggested having a presentation prior to the 
utility rate increase for residents to better understand the need for rate adjustments. He 
emphasized the importance of maintaining infrastructure and acknowledged past efforts that built 
Mesa’s reliable water system. 
 
Mayor Freeman raised concerns about a proposed state bill that would impose a four-year 
moratorium on municipal fee and rate increases, warning of limitations on the City’s ability to 
respond to funding for the City’s needs. 
 
Mayor Freeman thanked staff for the presentation.
