Lake County residents file lawsuit to block 472-acre data center campus in Grayslake
Lake County residents and a corporation have filed a lawsuit to block the 472-acre T5 @ Chicago IV data center campus in Grayslake, alleging that its approval was inconsistent with village plans and lacked adequate public disclosure. The plaintiffs challenge the Village of Grayslake's approvals, which were granted in 2024 and 2025 for a project of "unprecedented scale". T5 Data Centers has suspended its wetlands permit application due to community concerns, while the Lake County Board is considering a temporary moratorium on data centers in unincorporated areas.
