Panattoni Development took over Project Cornmaze, a data center proposal on active quarry land along Prairie Avenue in the towns of Beloit and Turtle. Meta signed a pre-development agreement for the site in 2026. The concept called for about 2 million square feet of buildings on both sides of the industrial land, built over about five years.
The project stalled in mid-2026. The Town of Turtle rejected Panattoni's cost agreement, and both towns adopted 12-month moratoria on data centers in August 2026.
