Rifle Range Road computing center (north of Marshfield)
Lumon Solutions is building a small 'AI-ready' computing center on 5 acres off Rifle Range Road north of Marshfield. The county says it will use a closed-loop cooling system and a private well, and the company asked for no tax breaks. Webster County has no zoning, so it had little say.
Where things stand: Site work started in spring 2026. The county said in June it cannot stop a project already under construction.
🕒 Latest update (June 16, 2026): County adopted a six-month pause on new data centers, but said it would not use it to stop this project.
