Notes on the record

Lumon Solutions Marshfield, LLC (formed October 2025) is developing a 5-acre, Tier III, AI-ready facility described as eight modular units on land owned by ARY Investments LLC; building-size figures differ between the county (~14,000 sq ft) and the developer (~7,000 sq ft). Webster County has no planning-and-zoning ordinance, limiting county jurisdiction. Site preparation began without public notice, prompting community opposition and discussion of a possible county moratorium. Developer claims on water/power/noise impact are not independently verified.
