Case File · Mesa, Maricopa County, AZ
Air-cooled. $1 billion. Approved —
but Mesa is tightening the rules.
Google navigated Arizona's water concerns by committing to air-cooling technology. Mesa approved a 25-year GPLET tax incentive for a $1B campus on 185+ acres. Phase I went operational in July 2025. Then the city moved to regulate data center growth.
RealClear scores this site 72/100 — approved and operational, but the regulatory environment has shifted for new entrants.

July 2019
Google signs 25-year GPLET with Mesa
Mesa City Council approves a Government Property Lease Excise Tax agreement with Google, providing an estimated $16M in property tax savings over 25 years. The deal anchors Google's commitment to build a $1B data center campus on 185+ acres of industrial-zoned land in the Elliot Road Technology Corridor.
2023
Groundbreaking on Phase I
Google breaks ground on the first 288,000-square-foot building. The project commits to air-cooling technology — no evaporative water use for server cooling — a critical concession in drought-prone Maricopa County where water consumption is the dominant opposition vector for industrial development.
2024
Design Review Board gives low marks; Council approves anyway
Mesa's Design Review Board flags aesthetic concerns about the facility's industrial appearance. Despite the low marks, the City Council approves the project, prioritizing the economic impact and job creation over design critiques. The GPLET and development agreement provide contractual protection.
July 2025
Phase I goes operational — 288K SF live
Google's first building goes operational at 288,000 SF. The air-cooled facility demonstrates that hyperscale data centers can operate in desert climates without consuming municipal water for cooling — a proof point that reshapes the water-usage debate for Arizona data center development.
2025
Mesa adopts DC-specific zoning regulations
With 15 data centers on 1,500 acres and growing, Mesa adopts new data-center-specific zoning regulations. City staff publicly acknowledge they want to 'slow that train down.' Google's campus is grandfathered under its existing development agreement, but new entrants face additional waiver requirements and regulatory scrutiny.
2027
$800M investment milestone
Google reaches $800M in cumulative investment at the Mesa campus, triggering additional phases of the development agreement. The campus is now one of Mesa's largest single-site employers in the technology sector.
2029–2030
Full $1B buildout — 750K SF at completion
Google's Mesa campus reaches full buildout at 750,000 SF across 185+ acres. The $1B investment is fully deployed. But the regulatory environment that made the original deal possible no longer exists for competitors seeking to enter Mesa's data center market.
The Water Strategy
Air-Cooling Commitment
In Arizona, water is the opposition weapon. Google committed to air-cooling technology — no evaporative water use for server cooling — before the first council meeting. This single concession eliminated the strongest argument opponents could have made in a state where municipal water allocations are under intense scrutiny.
The Incentive Structure
25-Year GPLET
Mesa's Government Property Lease Excise Tax agreement provides approximately $16M in property tax savings over 25 years. The GPLET structure — where the city technically owns the land and leases it back — is a standard Arizona incentive tool for large industrial projects. It locked in favorable economics before the regulatory environment shifted.
The Regulatory Shift
DC-Specific Zoning (2025)
Mesa's 2025 data-center-specific zoning regulations were a direct response to the concentration of 15 DCs on 1,500 acres. City staff publicly sought to 'slow that train down.' Google is grandfathered, but new entrants face waivers, design requirements, and additional scrutiny that did not exist when Google signed its GPLET in 2019.
The Precedent Pattern
First-Mover Advantage
Google entered Mesa before the regulatory backlash. The pattern repeats across data center markets: early entrants secure favorable terms, the concentration of facilities triggers community and political concern, and late entrants face a harder regulatory environment. The development agreement grandfathers Google, but the door behind them is closing.
Key Decision Makers & Stakeholders
The people who shaped this project's outcome.
Mesa City Council
Municipal Governing Body
Mesa, Arizona
Documented Record
Approved the 25-year GPLET agreement in July 2019, providing Google an estimated $16M in property tax savings. Council voted to approve the project despite the Design Review Board's low aesthetic marks in 2024, prioritizing economic impact and the air-cooling commitment.
The Council's support was driven by the economic calculus: a $1B investment, hundreds of construction and permanent jobs, and a marquee tenant for Mesa's Elliot Road Technology Corridor. The air-cooling commitment removed the water argument that could have fractured council support in drought-conscious Arizona.
Vice Mayor Jenn Duff
Mesa Vice Mayor
Mesa, Arizona
Documented Record
Cast the sole dissenting vote on the Google GPLET agreement. Duff's opposition was documented in council records as the only 'no' vote on the development agreement that provided 25 years of property tax incentives.
Duff's lone dissent signals that even in a pro-development council, the scale of incentives for data center operators generates internal friction. Her vote did not block the project but represents the political undercurrent that eventually produced Mesa's 2025 DC-specific zoning regulations.
Mesa City Staff
Planning and Development Department
Mesa, Arizona
Documented Record
City planning staff publicly acknowledged the need to 'slow that train down' regarding data center growth in Mesa, citing the concentration of 15 DCs on 1,500 acres. Staff drove the development of the 2025 DC-specific zoning ordinance that added new waiver requirements for future facilities.
The staff's public comments reveal the tension between economic development and land-use management. They supported Google's project under the existing framework but recognized that unchecked DC growth was consuming industrial land faster than the city's planning framework anticipated. The 2025 regulations are staff-driven, not council-driven — an important distinction for future applicants.
“What if you knew — before signing — that the city would change the rules two years after your groundbreaking?”

Regulatory Warning
Mesa has 15 data centers on 1,500 acres. In 2025, the city adopted DC-specific zoning regulations. Google is grandfathered under existing development agreement, but new entrants face additional waiver requirements.
Applicant Strategy
Commit to air-cooling technology early in the process. In drought-prone Arizona markets, water consumption is the dominant opposition vector. Developers who eliminate evaporative cooling from their designs defuse the strongest community argument before it forms.
Recommendation
FAVORABLE WITH CAVEATS. Existing development agreements are strong. New entrants should confirm whether site has pre-existing GPLET or will require new regulatory approval under Mesa's 2025 DC-specific zoning ordinance.
The Decision Framework
Three signals. All publicly available.
What RealClear would have surfaced before the first dollar of entitlement spend — and what it surfaces now for anyone screening Mesa.
Water Is the Opposition Vector — Air-Cooling Is the Answer
Zoning ReaderGoogle's air-cooling commitment was the deal-maker in drought-prone Arizona. RealClear's Zoning Reader would have flagged water as the dominant opposition vector and recommended cooling-technology commitments before the first council meeting. In arid-climate DC fights, the developer who commits to zero evaporative cooling defuses the strongest argument against them.
Check for Existing Development Agreements — or Plan for New Regulations
Pathway MapperMesa's 2025 regulatory shift means new DC proposals face a different environment. Screen for whether the site has an existing GPLET or development agreement, or will need new regulatory approval. Google's grandfathered status protects its expansion, but a new entrant in Mesa today starts from a fundamentally different position than Google did in 2019.
Water Is the New Opposition Weapon in Arid-Climate DC Fights
Community SentinelPattern: Water consumption has replaced traffic, noise, and aesthetics as the primary community objection to data centers in the Southwest. Air-cooling technology is the mitigation that works. Developers who commit to zero evaporative cooling defuse the strongest argument against them — and municipalities are beginning to require it. RealClear's Community Sentinel tracks this pattern across 25+ states.
The lesson from Mesa:
First movers in data center markets lock in favorable incentives and by-right entitlements. But the concentration of facilities triggers regulatory backlash. Google's air-cooling commitment and early GPLET secured $1B in development. Late entrants face a different Mesa — with new regulations written specifically for them.
Lock in your entitlements before the regulatory window closes.
