Questions left unanswered on extension request for Yorkville’s Project Cardinal data center

Developers for the 1,034-acre Project Cardinal data center in Yorkville, Illinois, have requested an 18-month extension to close on the property, citing "unforeseen consequences." The current deadline is July 1, and failure to close by December 31, 2027, would nullify already approved agreements, including the annexation agreement and a $51 million development agreement. The Yorkville City Council held a public hearing on June 9, where residents voiced substantial concerns and frustrations, particularly regarding a lack of explanation from city staff or officials about the extension request.

Residents, some of whom have formed the community-based organization Preserve Our Yorkville & Community LLC, have already sued the city and the developers of both Project Cardinal and the 540-acre Project Steel data center, alleging inadequate public notification and insufficient studies on environmental impacts, noise, traffic, and property values. During the hearing, residents called for a moratorium on data center construction until comprehensive environmental and health studies are completed and requested that future data center approvals be put to a public vote. The city has also introduced new water usage penalties for Project Cardinal, setting limits of 71,400 gallons per day or an average of 42,000 gallons per day over a billing cycle, despite residents' criticism of the city inviting "water hogs" while advocating for water conservation.
