Notable ⁠statements

We really need to make a decision tonight, I implore you to do so, so that we don't have to fall back on another extension on that moratorium. — Anonymous Aurora resident · Urging the council to finalize data center regulations to prevent new applicants from bypassing stricter rules during an interim period. ▶ 18:00
We're willing to make compromises to try to address some of the concerns. We're willing to go to quarterly instead of monthly [generator testing]. — Kevin Lennon (CME Group) · Representing a long-standing data center tenant offering to adjust testing schedules to mitigate community noise concerns. ▶ 38:54
The city suggests that there should be... clear day and nighttime noise limits... but what about all the other properties of sound that are being completely ignored? — Marcy Kirsch · Criticizing the city's proposed noise ordinances for failing to account for low-frequency sound/hertz levels. ▶ 59:54
I strongly support restricting data centers to M2 zoning only. — Speaker Z (Mr. Chaudhary) · Public comment regarding proposed data center regulations. ▶ 68:53
If we limited it as the plan commission suggested [M2 only], there are none [developable sites]. — Unidentified speaker · Discussing the impact of a 0.5-mile buffer on available development land. ▶ 105:46
Do we think that would be enough to push us over the line into being considered exclusionary zoning, legally? — Speaker S37 (Alderman Larson) · Questioning the legal risk of highly restrictive separation buffers. ▶ 107:19
