Linn County (IA) — 18-Month Moratorium on Large-Scale Data Center EU-3 Rezoning Applications
Linn County, Iowa · Linn County (IA) Board of Supervisors Resolution — 18-month EU-3 data-center rezoning moratorium (July 1, 2026)
Linn County, Iowa (home to Cedar Rapids) voted 2-1 on July 1, 2026 to impose an 18-month moratorium pausing all new EU-3 Large-Scale Data Center Zoning District rezoning applications in unincorporated areas of the county. The moratorium is effective immediately through January 1, 2028, and gives the county time to conduct a comprehensive planning process to address data center siting, water use, energy consumption, and community impact. Note: this is a separate and additional measure from the existing Linn County data-center zoning ordinance (February 2026), which established the EU-3 zone; this moratorium pauses NEW rezoning requests under that zone.
