Indianapolis Proposes Moratorium on New AI Data Centers Amid Zoning Overhaul
City leaders consider 'SU-47' rules for noise, buffers, and mandatory resource reporting.
Indianapolis City-County Council President Maggie A. Lewis introduced a surprise amendment on July 13, 2026, to establish a moratorium on all new data center approvals. The proposed pause aims to give city leaders time to finalize the first zoning regulations specifically designed for hyperscale AI infrastructure, known as Proposal SU-47.
Key details
The proposed zoning overhaul, SU-47, introduces strict operational requirements for any future data center project in Marion County. Key provisions include:
- Mandatory Resource Reporting: Facility operators must provide regular public reporting on their consumption of water and electricity.
- Noise Limits: Sound levels are capped at 65 decibels at the property line, addressing community concerns over the constant hum of cooling fans.
- Buffer Zones: The rules require a 400-foot separation between a data center's primary building and protected areas like homes, schools, and churches.
- Operations Plans: Developers must submit detailed plans for generator testing and decommissioning.
While the city's proposal marks a significant increase in oversight, a coalition of local residents is pushing for even stricter measures, including buffer zones ranging from 750 to 2,500 feet depending on the facility's electricity demand.
Why this matters
The moratorium and the SU-47 proposal signal a shift toward greater transparency in how AI infrastructure impacts local resources. By mandating public reporting of water and electricity use, Indianapolis joins a growing number of municipalities seeking to quantify the "invisible" footprint of AI training and inference. The 65-decibel noise limit also directly addresses the physical environmental impact on urban and suburban neighborhoods.
Context
Indianapolis is currently experiencing a surge in data center interest, following the broader "Silicon Heartland" trend seen across Indiana and the Great Lakes region. This move follows similar moratoriums and regulatory pushes in states like Virginia and Oregon, where the rapid expansion of AI compute loads has begun to strain local power grids and water tables.
What happens next
The City-County Council's Metropolitan and Economic Development Committee is scheduled to hold a public hearing on the SU-47 zoning amendment. The moratorium proposal will likely undergo further debate to determine its duration and whether it will affect projects currently in the application pipeline.
