# Planning and Zoning Commission - 09/17/26 5:00 pm

The City of Marshalltown Planning and Zoning Commission held a work session on September 17, 2026, focused primarily on reviewing and revising ordinances related to data center regulations and associated zoning code amendments. Key procurement-related discussions included the establishment of thresholds for master development plan reviews based on development scale, infrastructure intensity (such as electrical demand over 25 megawatts and water usage over 75,000 gallons per day), and vehicle trip generation. The commission debated overlay district zoning for data centers, special use permits, and the procedural requirements for annexation and zoning changes. They also discussed noise control regulations for generator testing and backup power generation, including restrictions on on-site power generation to ensure grid connection. The commission planned a public open house on October 1, 2026, to gather community input on draft revisions, followed by a special work session on October 8 and a potential public hearing on October 15. No specific contract awards or vendor selections were mentioned, but the ordinance changes could impact future development projects and infrastructure procurement in the city.
