Ohio's Wilmington City Council has postponed voting on a 471-acre data center campus proposed by Amazon Web Services (AWS).

During a November 25 meeting, councilors decided to delay voting on the project until December 4 to consider the application and pushback from local residents, reports the Wilmington News Journal.

The vote pertains to the approval of Ordinance O-25-73, which would see AWS, the city, and the Clinton County Port Authority agreeing to a 'compensation agreement' for the data center project, including tax exemptions for AWS for up to 30 years.

The site is located off the US 68, with its listed address as 1588 South US 68.

AWS has said it will invest around $4 billion in developing the site, and will create at least 100 permanent jobs with a total annual payroll of $8bn. It will also invest $25 million in public infrastructure, including sewers, a water main, a water tower, and road improvements.

Around 40 residents spoke during the meeting, with many asking the council to reject the deal. Concerns raised included the proximity to homes and schools, noise pollution, and impacts on the water supply. Additionally, with AWS having remained anonymous for much of the process thus far, residents were displeased with the "lack of transparency."

Councilors plan to review documents and speak further with the community before voting. Another meeting will be held on December 4, during which the Port Authority will be invited to address questions as well.

Wilmington is located to the northeast of Cincinnati.

AWS already has a significant presence in Ohio, operating its US East region in the state with three availability zones. Each availability zone has at least one data center, but can have multiple.

In late 2024, the company said it would invest $23bn in Ohio by 2030. The company operates data centers across Franklin and Licking counties in Ohio, is planning to build a five-building data center campus in New Albany, and has also expressed an interest in Pickaway County and shared plans to spend $2bn on a data center campus in Sunbury, Ohio.

Another campus in Fayette County, Southern Ohio, is also planned by AWS. News of the data centers first surfaced in November last year, with the company acquiring 590 acres in Jefferson Township in August 2025. Local filings suggest the campus could go live in 2026.

This year so far has seen AWS get approval for another campus in Ohio, located in Marysville, and in October 2025, AWS secured a tax break for a $3bn data center in Sidney, Ohio.

Recent reports citing leaked documents suggest that AWS could have more than 900 data centers globally, though AWS does not publicly share this data.
