The University of Michigan Center for EmPowering Communities designed this guide, with input from a variety of experts, to provide Michigan local government officials and planners, particularly those with zoning authority, with the information they need to effectively participate in data center siting conversations. Focused on local-level considerations, the guide aims to inform on both positive and negative impacts. Since policies, technologies, and best practices for data center siting are rapidly evolving, readers should treat this guide as a working document. The authors plan to revise it or add supplementary guides on this webpage as more is learned.
