What happened
On November 10, 2026 the Butler County Planning Commission unanimously recommended approval of a St. Clair Township zoning change banning data centers, where an 18-building, $5 billion AWS campus is proposed on 600 acres across Madison and St. Clair townships. The change returns to the township zoning commission and then trustees. Separately, lawyers for Trenton residents asked the city to revoke the zoning certificate for a Prologis-built AWS data center, citing the new 25 MW ban, and said taxpayers intend to sue. Prologis says the ban does not affect its project; AWS gave a general statement.
Why it matters
Shows township and county land-use powers can block AI data center capacity even after a state welcomes it, and that local ballot results quickly turn into zoning and legal action. Relevant to local governments weighing data center applications and to state economic development offices.
Evidence and measured results
Independent local reporting on a public hearing and a lawyers' letter. The ban is not final; the lawsuit is threatened, not filed.
Limitations and uncertainty
Recommendation, not final adoption. AWS's response was a general statement. Trenton vote was archived earlier; this item reports new county action and a legal demand.

Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
No technical content; affects where AWS capacity can be built.
Governance
Who approves, reviews and stays accountable for outcomes?
Illustrates multi-step local approval paths (township zoning commission, county planning, trustees) and use of moratoriums while rules are written.
Security and privacy
What data, permissions and controls need testing?
No security content.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Residents raised water, noise, light, groundwater and quality-of-life concerns.
Procurement
What should contracts, pricing and exit terms secure?
Not a procurement action; affects state and local economic development commitments.
Operating model
Which teams own the service once it runs?
Local governments need staff capacity for hearings, moratorium management and potential litigation.
