Planning & Zoning - 10/08/26 5:00 pm

The City of Marshalltown Planning and Zoning Commission met on October 8, 2026, to review draft zoning and related ordinances, with substantial discussion focused on regulating data centers. Staff reported feedback from two listening sessions, including concerns about siting, scale, water and private wells, noise, enforcement, decommissioning, and extending the moratorium. Commissioners generally favored using a designated overlay area—discussed as east of 18th Street and north of Marian Street—with a special-use-permit process for data centers elsewhere in general industrial areas. Most members also expressed concern that a master development plan review could create public expectations of influence the commission may not have in a quasi-judicial proceeding; this was discussion rather than a recorded formal vote.

The commission reviewed draft provisions addressing noise, buffering, well protections, mandatory water connections, and annexation procedures. Members retained the proposed 300-foot separation for noise-generating equipment for now and requested further research on building setbacks, including whether setbacks should vary by height. Staff recommended holding the five scheduled public hearings at the next meeting, while noting the commission could continue hearings or defer action; a possible recommendation to extend the moratorium may also be placed on that agenda. No procurement activity, contract awards, vendor selections, or spending decisions were identified, and the transcript does not record formal votes or motions.
