Opposition and litigation at this site

Nothing on record as of October 14, 2026. No lawsuit, organized opposition, or contested hearing over Google Columbus Data Center (South High St / Rathmell Rd, former Hartman Farm) in Columbus, Franklin County, Ohio appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

Notes on the record

Google's Ohio page names Columbus as one of its three Ohio data center communities. The 2021 application ($300M, 150k sq ft, 20 jobs) describes the first building only, and the campus has since grown. Epoch's MW figures are model estimates and are not recorded as capacity. The parcel-to-S. High St link rests on matching location (south of I-270 on US 23) and the Magellan shell entity, so the pin is approximate.

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
How the community has received it
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.
How the community has received it: Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Which utility serves it: The electric service agreement or the utility's filing with the state public utility commission.

Have one of these documents? Send it to us and we will add it to the record with attribution.

Other sites within 30 miles

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
