Residents in Yorkville, Illinois, are intensifying their opposition to the city's extensive data center development plans, which encompass nearly a dozen projects across approximately 3,000 acres along the Eldamain Corridor. On Saturday, April 11, community members gathered at Town Square Park for a "Say No To Data Centers" event, protesting against what they describe as ignored concerns by elected officials regarding potential sound, light, and environmental pollution, as well as the long-term impact of 10-20 years of construction.
Key projects under consideration or already approved include the 1,034-acre Project Cardinal, the 540-acre Project Steel, and a 228-acre CyrusOne data center. City Administrator Bart Olson has previously highlighted the significant financial benefits, estimating each building could generate $500,000 to $1 million in annual tax revenues, alongside substantial upfront payments like $51 million from Project Cardinal and $40 million from Project Steel, subject to final approval. These funds are earmarked for the Yorkville School District 115, the fire district, city projects, and charitable organizations.
Despite the city's assurances, including a 500-foot setback requirement from residential or commercial structures, residents like Leesa Poss voice strong objections. Poss, a frequent critic at City Council meetings, emphasized that these projects threaten the community's environment, infrastructure, property values, and overall quality of life. She stated that residents demand transparency, accountability, and a genuine voice in decisions that will shape their future, rather than decisions perceived as being made behind closed doors.
Poss confirmed that an organized group of residents has retained an attorney to "ensure our voices and rights are properly represented." The group plans to continue their presence at city meetings and organize additional public protests, with Poss asserting, "We are not backing down."
