Summary
Aurora, Illinois amended its zoning chapter so a "Data Center Facility" is a defined use that needs a conditional use approval in office, research, light industrial and industrial areas. Applicants must file baseline sound, noise-modeling and water-consumption studies, and facilities must meet noise, vibration, water-usage-effectiveness, screening and decommissioning standards. The City Council adopted the ordinance as amended on 24 March 2026. A companion ordinance adopted the same day (File 26-0092) adds city code chapters on data center performance standards, operational reporting and privacy.
What this does not establish
- The terms were read in Exhibit A "FINAL (with CC Modifications)" attached to the Legistar file; the signed ordinance number and publication date were not opened, so no effective date is stored.
- Specific noise thresholds and screening details are not restated here.
- The earlier 180-day moratorium (File 25-0731, adopted 25 September 2025) is a separate instrument and is not part of this record.
- This is an Aurora city ordinance; it does not apply elsewhere in Illinois.
Unresolved questions
- The ordinance number and effective date.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
- Related, not a replacement Aurora: data center performance, reporting and privacy code chapters (File 26-0092) (In effect)
