190. Zoning, Wineries and Rural Change: What Old Mission Teaches Us_PX

In this episode of PlanningxChange, Jess and Peter speak with Mary Reilly, a planner and educator with deep experience in rural land-use issues. Mary helps us unpack the widely discussed Old Mission case from Michigan - a dispute between wineries and a township over land-use controls that resulted in a major federal damages award (approx $50m US). The discussion does not explore the legal merits or the ongoing appeal; instead, it uses the case to illuminate broader lessons for planners everywhere. Mary reflects on how agricultural areas are changing, how councils manage risk, and how planning systems can better balance rural preservation with economic adaptation. She also draws on her teaching experience to explain how real cases help future planners understand complexity, conflict, and the value of clear decision-making. Five Key Themes We Explore 1. What the Old Mission case reveals about zoning and regulation Mary outlines how restrictive controls can create tension when agricultural enterprises diversify into tastings, events, weddings and food service — activities that increasingly blur the line between “farm” and “commercial.” 2. Balancing preservation with economic survival Many farms depend on supplementary income. Mary discusses how planners can support this economic reality while still protecting landscape character, amenity and long-standing rural values. 3. Managing risk for councils and planners A large damages award raises questions about insurance coverage and liability. Mary talks about how planners can help councils navigate uncertainty through clearer drafting, transparent process and sound policy grounding. 4. The unique pressures on small rural municipalities Old Mission, like many small townships, has limited planning resources. Mary explores how smaller councils can respond to complex disputes and why early community engagement can prevent escalation. 5. Lessons for planning education and practice Drawing on her academic work, Mary explains how real planning conflicts — like Old Mission — help students and practitioners think critically about regulation, equity, and the evolving expectations placed on rural land.
