1/21/2026, 11:22:18 PM
Overview of the Decision
The Naperville City Council voted 6 to 1 to deny a proposal for a Karis Critical data center during a late-night meeting on Tuesday. The decision followed months of public debate and concerns raised by residents regarding the project's potential impact on the community. The proposed facility, which was to be located on the former Lucent campus along the Interstate 88 corridor, would have encompassed approximately 145,000 square feet and included diesel generators.
Community Concerns
Residents expressed significant opposition to the data center, citing worries about noise, air pollution, and its proximity to homes, parks, and schools. Over 5,400 residents signed a petition against the project, emphasizing that the industrial nature of the facility was incompatible with the surrounding residential area. Council member Ian Holzhauer noted that the decision was made after extensive public comment and review, highlighting the community's strong sentiment against the development.
Developer's Response
Karis Critical, the developer, expressed disappointment with the council's decision, which contradicted the earlier recommendation from the city's Planning and Zoning Commission, which had voted 8 to 1 in favor of the project. The company had proposed reducing the number of diesel generators from 24 to 12 in an effort to address community concerns. Karis Critical's Executive Vice President, Greg Strom, defended the project, asserting that the facility would not negatively impact public health and that the generators would only be used during power outages and monthly tests.
Official Statements & Responses
City officials indicated that the denial of the data center could lead to legal action from Karis Critical. They also mentioned that alternative developments could still be pursued for the site. Council member Patrick Kelly stated that the proposal did not meet the necessary criteria for a conditional use permit, particularly regarding public health and property values. He expressed support for residential or mixed-use developments instead.
Criticism & Opposition
Opposition to the data center was vocal and widespread. Residents raised concerns about the potential for increased emissions and noise from the diesel generators, with some citing health risks associated with diesel emissions. Dr. Sujay Shah, an oncologist and resident, emphasized that the proposal failed to meet the standards required for conditional use, arguing that the health and welfare of the community should take precedence.
What's Next
Following the council's decision, it remains unclear what type of development may be proposed for the site in the future. City leaders have not provided specific details on alternative plans, but the rejection of the data center has set a precedent that may influence similar projects in the region.
