Dublin Locks Data Centers Out of 370-Acre West Innovation District, Creates New Research Zone

Dublin City Council voted July 1 to ban data centers from the West Innovation District and replace the corridor's development blueprint with zones aimed at research, advanced manufacturing, and office uses — a sweeping rezoning of roughly 370 acres that rewrites what can and cannot be built along one of the city's last major growth frontiers.

The overhaul converted acreage previously zoned Rural District into a mix of three new classifications: the newly created ID-6 Research Transition District, along with ID-2 Research Flex and ID-3 Research Assembly. Under the updated code, data centers are no longer permitted or conditional uses anywhere in the West Innovation District. City officials said at the time of the rezoning that no active data center proposals were pending and no new facilities were under construction in the district.

What the new zones allow — and don't

The ID-6 district, the centerpiece of the overhaul, permits general and medical offices, research and development, small-scale advanced manufacturing in fields such as robotics and 3D printing, indoor contract and construction services, and parks and open space. Retail sales, wholesale distribution, and customer pickup are prohibited as principal uses; warehousing may operate only as an accessory to a permitted use.

ID-2 Research Flex casts a wider net, allowing conference centers, indoor entertainment and recreation, fitness facilities, offices, educational institutions, hospitals, research and development, manufacturing and assembly, and parks and open space. Notably, data centers remain listed as conditional uses in ID-2 — but the separate code amendment stripping data centers from ID-1 through ID-3 and ID-6 overrides that. ID-3 Research Assembly permits offices, educational and institutional facilities, hospitals, research and development, manufacturing and assembly, industrial uses, and warehousing and distribution.

Buffers for Cosgray Road neighbors

Residents along Cosgray Road won substantial protections. The rezoning requires a minimum 150-foot setback when development abuts residential zoning, widened to 200 feet along Cosgray Road itself. Service areas, loading docks, and overhead bay doors are banned along the Cosgray frontage. The ordinances also adopted the West Innovation District Screening and Setback Design Manual, codifying enhanced buffering requirements along the corridor.

Mayor Chris Amorose Groomes called the protections among the strongest the city has imposed. "The ID-6 setback and screening requirements would be as good or better than anywhere in the city," she said.

Those protections matter in part because of what already surrounds the district. Amazon Web Services operates a data center campus on Houchard Road in Dublin and another on Cosgray Road in neighboring Hilliard; residents have noted they sit between the two facilities. The AWS Dublin campus carries an electrical load comparable to about 144,000 homes and is driving rapid growth in regional electricity demand, raising concerns about grid capacity and future power prices across Central Ohio. Hyperscale data centers typically require more than 100 megawatts of power and can consume tens of thousands to millions of gallons of water per day for cooling. The city's rezoning page notes funding for a 2026 Cosgray Road alignment study and ongoing coordination with AWS on operational noise concerns affecting adjacent neighborhoods.

Contentious path to a vote

The decision followed months of heated public input. At the June 8 City Council meeting, fourteen residents spoke and seven submitted written comments — all opposing the rezoning plan. Concerns ranged from air pollution, traffic, and health impacts to falling property values and the loss of residential character near Ballantrae. The debate echoed a broader statewide backlash: residents from across Ohio, including Central Ohio communities, packed the Statehouse in June to demand a moratorium on new data centers, citing energy use, noise, and environmental harm.

The Planning and Zoning Commission recommended the code amendments on a 5–1 vote May 21. Council itself debated the ordinance for more than two hours at its June 12 meeting before scheduling the July 1 vote.

"Not everyone will leave happy but the city is committed to making residents feel heard and to responding to their concerns," Amorose Groomes said.

Split votes, two dissenters

The two measures passed on different margins. Ordinance 33-26, which amended the zoning code to strip data centers as permitted or conditional uses across ID-1 through ID-3 and the new ID-6, passed 6–1. Ordinance 06-25 (Amended), which rezoned the 370 acres from Rural District to the new classifications, passed 5–2.

Ward 2 Council Member Wendy Johnson and at-large Council Member Christina A. Alutto cast the two no votes on the rezoning measure. Voting yes were Ward 3 Council Member Greg Lam, Ward 1 Council Member Amy Kramb, Vice Mayor Cathy De Rosa, Mayor Amorose Groomes, and Council Member Andy Keeler.

Tax-base trade-offs

The financial calculus is anything but simple. Data center buildings in the New Albany and Columbus market can appraise at $225–$300 per square foot, compared with $60–$100 per square foot for typical industrial or manufacturing buildings. But Ohio data centers routinely receive property tax abatements lasting 15 to 30 years — and sometimes 65 to 100 percent off the tax bill. Even with steep abatements, some facilities have become top taxpayers: a Stark County project was projected to become the county's single largest taxpayer despite a 75 percent property tax exemption. Amazon, Meta, and Google currently benefit from statewide tax deals for Ohio data center facilities extending through at least the mid-2050s.

Dublin's own analysis found that office and research-and-development buildings in the local market generally produce higher property tax revenue per square foot than data centers, though data centers can carry very high assessed values because of specialized infrastructure. The actual taxable outcome varies widely depending on ownership structure, energy equipment treatment, and incentive agreements.

At full buildout, the West Innovation District is projected to generate approximately 3.9 million square feet of development, about 10,500 jobs, and roughly $711–$712 million in annual payroll — translating to about $14 million a year in municipal income tax revenue at Dublin's 2.0 percent rate. For context, Dublin's 2025 income tax collections totaled $118.1 million; the income tax is the city's largest funding source for services and capital improvements.

What comes next

Council unanimously directed staff on July 1 to begin reviewing the ID-2 and ID-3 portions of the zoning code, using the ID-6 process as a template — a signal that the rules governing research and assembly uses could tighten further.

The questions the rezoning leaves open mirror those still echoing at the Statehouse. At a lengthy Joint Data Center Committee hearing in June, Ohio lawmakers pressed lobbyists from Amazon, Google, Meta, and Microsoft about the rapid buildout of data centers statewide. Despite hours of testimony, legislators said key questions about local infrastructure burdens, transparency, and long-term corporate commitments remained unresolved.

Dublin has drawn a clear line on 370 acres. Whether the research-and-office future it is betting on delivers comparable jobs, tax revenue, and infrastructure relief — and whether the ID-2 and ID-3 review reshapes the district further — are the accountability questions residents, property owners, and prospective developers now need answered.
