A settlement in a lawsuit against the Project Cardinal data center in Yorkville, Illinois, has been delayed due to a second resident-led lawsuit. This new legal action targets the city and developer, Pioneer Development LLC, alleging failures in resident notification regarding annexation and rezoning for data center construction. Separately, the Yorkville Mayor announced the City Council no longer has an appetite for new data center proposals, leading to one developer withdrawing a project.

A legal settlement concerning the 1,034-acre Project Cardinal data center in Yorkville, Illinois, faces an indefinite delay following the filing of a second lawsuit by area residents against the United City of Yorkville and developer Pioneer Development LLC. During a May 8 status hearing before Kendall County Judge Robert Pilmer, attorneys requested an extension until May 22 to assess the new lawsuit's impact on ongoing settlement negotiations with resident John Bryan, who initially sued over concerns about property values and quality of life.
The latest lawsuit, filed by "Preserve Our Yorkville & Community LLC" and other plaintiffs on April 29, alleges that the city failed to properly notify residents about plans to annex unincorporated Kendall County land and rezone it for data center manufacturing. This community group explicitly aims to halt data center construction through legal challenges. Attorney Matt Klepper, representing Pioneer Development LLC, confirmed the need for time to evaluate the new legal action's implications.
This development comes as Yorkville Mayor John Purcell announced during an April 14 City Council meeting that the city has lost its "appetite" for new data center proposals, leading to the withdrawal of the 80-acre Meyer data center project. The city had previously entertained numerous proposals for a "data center alley" and has already approved the 228-acre CyrusOne data center, Project Cardinal, and the 540-acre Project Steel data center.
