Residents press council on data center noise, lights and buffers as West Innovation rezoning and code amendments move to second reading

City planning staff introduced two linked items affecting the West Innovation District: (1) a proposed rezoning of nine parcels — about 370 acres total — into ID‑2 (Research Flex) and ID‑3 (Research Assembly) districts; and (2) a package of zoning code amendments to clarify the concept plan process, refine West Innovation District uses, amend temporary sign rules for special events, and update the property nuisance section.

Zach Hounshell, planning staff, told council the rezoning aligns with the recently adopted Envision Dublin community plan and the West Innovation District Special Area Plan. The rezoning covers nine parcels of roughly 370 acres (including two city‑owned parcels) and is intended to enable “flex innovation” uses along Cosbury Road and heavier industrial/assembly uses closer to the rail corridor. Planning & Zoning recommended approval; staff asked council to schedule the second reading public hearing for April 7.

Public commenters asked council to slow the process, investigate noise and lighting impacts from data centers, and improve resident notice. Lynn Roose (5830 Hootrip Road) urged an environmental impact review, described ongoing audible/physical hums near the existing Amazon data center and cited World Health Organization materials about low‑frequency exposures. Linda M. Porter (Valatay) said she and neighbors hear a humming noise and worry about increased lighting. Both asked for more resident outreach and study before approvals.

Staff responses: Planning staff and city administration said zoning applications themselves do not evaluate low‑frequency noise but that nuisance and property‑maintenance codes are the appropriate enforcement channels for ongoing noise or light issues; individual developments will go through Administrative Review Team (ART) or Planning & Zoning and may require noise mitigation and environmental review as part of site‑specific approvals. Jenny Rauch, planning staff, described code changes intended to make concept plans “discussion only” (nonbinding) across districts to increase predictability for applicants and reduce duplicated approvals. The proposed amendments would also make assembly and manufacturing permitted in ID‑2 while making data centers conditional uses in ID‑2; data centers remain permitted in ID‑3.

Council and staff asked for additional resident outreach and for code details (setbacks, buffering, lighting and utilities capacity) to be resolved in the next work sessions. A number of council members emphasized that a conditional‑use requirement for data centers in ID‑2 would permit more scrutiny of noise, lighting and buffering at the project level. Several council members asked staff to bring the code (Ordinance 07‑25) back for additional detail before the rezoning vote; staff agreed to return with responses and to coordinate inspections for any alleged lighting code violations.

Why it matters: The West Innovation District rezonings and accompanying code changes set the rules for future industrial, research and data center development on hundreds of acres. Residents near the sites reported ongoing noise and lighting they attribute to an existing data center; staff explained that many development‑level impacts are addressed at site plan/conditional‑use review and via nuisance laws.

Next steps: Council scheduled second‑reading public hearings for the rezoning ordinance and the code amendment package on April 7 and asked staff to meet with residents and to return with refined setback, buffering, lighting and utilities information.
