Why communities are pushing back against data centers in Iowa
Iowa communities and political candidates are debating how to manage the rapid growth of data centers, focusing on electricity costs, water use, tax incentives and local control. Linn County adopted requirements for data centers and later approved an 18-month moratorium on new rezoning applications for large-scale facilities while it reviews related regulations and infrastructure impacts.
Data center growth has become a significant issue in Iowa’s 2026 campaigns and local community discussions. Candidates Christina Bohannan, Rob Sand and Zach Lahn have proposed different approaches to data center taxation, infrastructure costs, environmental disclosures and local approval authority. Sand and Lahn both support ending state tax breaks, while Lahn has additionally proposed a temporary statewide moratorium and higher property taxes for data centers.
Residents and consumer advocates are concerned that new transmission infrastructure, substations and power generation could increase electricity costs for other customers, while water use remains a concern in communities facing pressure on groundwater and municipal systems. Supporters argue that data centers can bring investment and jobs and should pay the costs of serving them.
Linn County adopted data center requirements covering noise, traffic, emergency planning and water availability, then approved an 18-month moratorium on accepting new rezoning applications for large-scale data centers. State lawmakers are also considering proposals on energy and water reporting, utility tariffs and water-efficient cooling systems, while communities across Iowa develop their own rules.
