Consistency ensures that zoning and day-to-day land- use decisions are made in harmony with a community’s comprehensive (or general) plan. While consistency arose from aims of cities to manage mostly outward growth, the trend of development away from cities has changed in recent years. Given trends of growth back into cities, consistency is still as relevant as during the growth management era. But for this tool to be effective, planners must consider how consistency can be defined and positioned flexibly to meet the dynamic environment of the developed city. How should the comprehensive plan address consistency? Is this tool still relevant for planners today?
This issue of Zoning Practice considers how consistency is used in plan implementation to align zoning regulations and land use decisions with local plans. It makes recommendations based on case examples from across the United States for how planners and municipalities can build consistency by building stronger links between local codes, regulatory mechanisms, and existing local planning processes.
