Update (January 30, 2026) Our neighbors in Lisle are facing a similar situation. But this is even closer to their homes. Please consider signing their petition. https://c.org/KHzLWhgLqV UPDATE (January 21, 2026) WE DID IT! Thanks to all of your support, City Council voted to deny the request for the data center late last night with a 6-1 vote. Councilmembers Gibson, Holzhauer, Jain, Kelly, Syed, and White voted to deny the request, Councilman McBroom voted to approve, and Mayor Wherli and Councilman Wilson abstained. This goes to show that even a small act like signing a petition can make a difference. Thank You!!! UPDATE (January 14, 2026) The data center will be on the City Council agenda on Tuesday January 20 at 7:00 p.m. at 400 Eagle Street in the Council Chambers. We need everyone to come and fill the room to show our opposition to this project. Please sign and share this petition as we start on the home stretch! Thank you for your support!   UPDATE (November 27, 2025) Thank you for everyone who came out on November 19th! Your presence was amazing. Although the outcome wasn't what we worked for, we've heard feedback that our message was powerful. It did make a difference, and it will carry us to the next step. We've heard that the the project is trending toward being presented to City Council on December 16, 2025 at 7:00 p.m. at 400 Eagle in the Council Chambers. Please consider signing (and sharing!) this petition to keep our momentum going!! UPDATE (November 11, 2025) The hearing has again been continued.  The next hearing is scheduled for November 19, 2025, at 7:00 p.m.  This will be held at 400 Eagle in the Council Chambers.  This will be the 4th Planning and Zoning meeting on this proposal.  Thank you to everyone who turned out on November 5.  We need you to come back and fill the chambers.  Public comment has been closed, and we will likely witness the Planning & Zoning committee ask their questions of the petitioner.  We must be present and stand united against this data center in the heart of our neighborhoods.   UPDATE (October 27, 2025) The hearing has been continued to the November 5, 2025, 7:00 pm Planning and Zoning Committee meeting, to be held at 400 Eagle in the Council Chambers.  This will be the 3rd Planning and Zoning Meeting on this proposal.  At the October 15th Planning and Zoning Meeting, the developer reduced the development to one 211,000-square-foot data center.  Numerous promises were made regarding power, water, noise, and emissions.    The neighbors still stand by their view that this heavy industrial use is not appropriate next to residential neighborhoods.   Continued Critical Missing or Incomplete Information after the updates made to the proposal: Power Source and Demand - The City of Naperville commissioned an independent study. This has not been released to the public. Naperville's power is 80% coal-generated, so it is not green or clean energy. Cooling and Water Usage - The proposed site sits atop an aquifer that supplies water to 45 nearby homes that use well water and to 150,000 Naperville residents who depend on municipal water. In addition to the use of 5,000+ gallons per month, there are environmental concerns about on-site diesel storage and lithium-ion batteries. Economic Benefit Data – No projections for permanent jobs or tax revenue. There is also no plan for the loss in home value due to a data center as a neighbor, nor for the adverse effects it may have on tax revenue. Continued Key Reasons for Denial  Permanent Environmental Damage – Destruction of greenspace and habitat near forest preserves; heat discharge from servers and cooling systems altering the local microclimate; and millions of gallons of water used annually for cooling, risking future shortages.
Health & Safety Risks – Diesel generator emissions (particulate matter, nitrogen oxides, sulfur dioxide) linked to respiratory illness and cancer; noise from cooling systems and generators disrupting sleep and well-being; and light pollution altering neighborhood character and night-sky visibility.
Infrastructure Strain – Potential overloading of the local power grid; increased stormwater runoff and flooding risk from massive impermeable surfaces; and significant traffic increases during construction and operation.
Economic & Community Harm – Decline in nearby property values from industrial-scale development; limited permanent job creation relative to the scale of the project; and loss of land that could be used for community-benefiting projects.
Lack of Transparency – No disclosure of the ultimate customer(s) or long-term commitments; unclear ownership or lease/purchase agreements; and no guarantee that the site won’t be abandoned if the operator leaves. With the updated promises or stewardship agreement, no oversight to make sure the developer keeps their promises. 
We strongly believe that no amount of “conditions” can fully mitigate these risks. Once built, the impacts of a single 211,000-square-foot data center will be permanent and irreversible. We urge the City of Naperville Planning and Zoning Commission to deny Case DEV-0057-2025 in its entirety to protect the health, safety, and quality of life of its residents.     (ORIGINAL PETITION FOLLOWS) Why the Proposed Data Centers Should Be Denied 
Prepared by the Neighborhoods of Danada Woods, FairMeadow, and Naperville Commons Case #: DEV-0057-2025 – Public Notice of Application  Applicant: Karis Critical, LLC  Location: Nokia property, identified by the parcel numbers listed in the public notice.  Hearing: Public Hearing before the Naperville Planning and Zoning Commission on Wednesday, September 3, 2025, at 7:00 p.m. in the Council Chambers at the Naperville Municipal Center, 400 S. Eagle Street, Naperville, Illinois. The applicant is seeking approval for:  Conditional Use – To allow the operation of a data center campus. Variance from Section 6-9-3 – Reduction of the required parking. Variance from Section 6-2-12.3 – Increase in height of the proposed equipment yard screen wall. Variance from Section 6-2-12.4 – Increase in height of the security fence to a maximum of 8 feet.  The proposal calls for the construction of two 211,000-square-foot data centers on the Nokia property in Naperville. While presented as economic development, this project poses serious, permanent risks to our community, environment, and quality of life. These impacts cannot be fully mitigated and will be irreversible once built. Critical Missing or Incomplete Information  Power Source & Demand – No disclosure of primary or backup power sources, total energy draw, or grid impact. Power study not shared with the public. Cooling & Water Usage – Not enough information about stated cooling method, water source, or estimated consumption, or potential changes in the future. Stormwater & Environmental Management – No stormwater management plan or environmental impact statement. Wildlife & Greenspace Impact – No assessment of habitat loss or effects on the neighboring forest preserves. Economic Benefit Data – No projections for permanent jobs or tax revenue. Without these details, the public and the city cannot fully assess the risks or benefits of this proposal.  Key Reasons for Denial  Permanent Environmental Damage – Destruction of greenspace and habitat near forest preserves; heat discharge from servers and cooling systems altering the local microclimate; and millions of gallons of water used annually for cooling, risking future shortages. Health & Safety Risks – Diesel generator emissions (particulate matter, nitrogen oxides, sulfur dioxide) linked to respiratory illness and cancer; noise from cooling systems and generators disrupting sleep and wellbeing; and light pollution altering neighborhood character and night sky visibility. Infrastructure Strain – Potential overloading of the local power grid; increased stormwater runoff and flooding risk from massive impermeable surfaces; and significant traffic increases during construction and operation. Economic & Community Harm – Decline in nearby property values from industrial-scale development; limited permanent job creation relative to the scale of the project; and loss of land that could be used for community-benefiting projects. Lack of Transparency – No disclosure of the ultimate customer(s) or long-term commitments; unclear ownership or lease/purchase agreements; and no guarantee that the site won’t be abandoned if the operator leaves.  We strongly believe that no amount of “conditions” can fully mitigate these risks.
