The Story So Far

$2.5 billion in tax breaks. About 75 jobs. The deal Ohio is signing in your county, with an NDA, before you hear about it.

In Mt. Orab, a 4,400-person village in Brown County, the mayor and every village council member signed nondisclosure agreements with a developer called DB Stu LLC before residents learned a 1,000-acre data center was coming to their town. In Piqua, a buried Nevada corporate filing eventually traced the developer J5 LLC to Meta’s Menlo Park headquarters — revealed only after the city had already approved $1 billion in tax abatements. In Trenton, a 141-acre, 250-megawatt Prologis campus — bigger than five Walmart Supercenters — was approved by the city planning commission in a 10-minute meeting that allowed no resident questions. In Lordstown, a $3.6 billion data center developer is suing the village in the Ohio Supreme Court for trying to ban them. The pattern is consistent: emergency ordinances, sealed agreements, and zoning votes that move faster than residents can organize.
