Wixom introduces renewable‑energy zoning, accessory use clarifications and overlay to address state law

The Wixom City Council voted to introduce a package of zoning amendments that add a new section for renewable energy facilities (section 18.26), clarify placement and standards for accessory solar panels and small wind turbines, and apply a renewable‑energy overlay to a set of industrial parcels.

Assistant City Manager Drew Benson and planning consultant Mateo Posalacqua explained the change as a protective, local response to Michigan Public Act 233 of 2023. That state law preempts local control for certain utility‑scale projects unless a municipality adopts a compatible renewable energy ordinance; the draft before council aligns with state requirements while creating a local overlay and permitting process. Posalacqua summarized thresholds cited in staff materials: roughly 50 MW solar facilities (commonly several hundred acres), 100 MW wind farms, and 50 MW battery storage (which can require far less land). He said the proposed overlay currently covers about 350 acres of targeted, underutilized M‑1 parcels and is intentionally concentrated south of Pontiac Trail to avoid adjacency to residential zones.

The draft also includes a Schedule B with standards for smaller‑scale projects that do not meet the state’s utility thresholds, and staff said the draft allows review of battery storage, rooftop solar and other non‑utility systems at the local level. Posalacqua cautioned that the Michigan Public Service Commission has issued interpretations of the law that are being litigated and that exact thresholds and allowable zoning practices could evolve.

Councilmembers asked about practical exposure in Wixom — staff and council noted that, with current technology and available parcels, battery storage is the most likely local application of the rules — and discussed whether the overlay should be broader. Planning commission recommended a focused overlay and reserved the city’s right to consider additional parcels later.

All three amendments were introduced by the council and advanced for final consideration, giving staff and the planning commission time to fine‑tune the overlay map and conditions.
