The Winnebago County Board of Supervisors in Iowa has commenced the process of drafting a new zoning ordinance to regulate a variety of facilities, including data centers, solar fields, industrial crypto facilities, and battery storage systems for electricity. Supervisor Susan Smith noted that the board is using Greene County's zoning ordinance as a foundational template for their updates.

Key issues to be addressed in the ordinance include water usage, with Supervisor Terry Durby highlighting that most new data centers utilize closed-loop water recirculation systems for cooling. Durby plans to propose specific noise level restrictions, suggesting a limit of 65 decibels for these facilities, as current state law lacks comprehensive noise regulations for cities and counties. This proactive measure by Winnebago County comes amidst concerns raised in neighboring Hancock County, where a data center moratorium has been voted down twice.
