How the community has taken it

Reception is a sourced signal, not an editorial judgment: contested means active public debate is on record, with hearings, petitions, or organized opposition, without litigation.

Madison Township and St. Clair Township trustees rejected Trenton's Type 3 expedited annexation petition in late August 2026, citing environmental and road-maintenance concerns, amid a dispute over competing TIF terms (townships: 10-year/75%; Trenton: 30-year/100%).

Notes on the record

Roughly 600 acres in Madison and St. Clair townships straddling Wayne Madison and Hawkins roads, reported as a second AWS campus of about 18 buildings with an estimated project value near $690 million. The reporting also references a separate 141-acre site already inside Trenton city limits; a 141-acre Prologis campus (Project Mila) is tracked separately at Trenton and no source read here links the two, so no relationship is asserted.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Power capacity in megawatts
  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • Which utility serves it
Which document closes each gap
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Which utility serves it
The electric service agreement or the utility's filing with the state public utility commission.
