Evaluating Plan Implementation: A Conformance-Based Methodology

The planning profession lacks a robust methodology to evaluate the implementation of plans. This article proposes a conformance-based plan implementation evaluation (PIE) that relies on the analysis of plans and permits to provide a rigorous, quantitative, and systematic way of assessing the degree to which land use plans are implemented. We studied the implementation of stormwater and urban amenity management in six New Zealand plans by reviewing their land development permits. We found that the implementation of land use plans was generally low and varied greatly among plans and issues. Although it was tested in the context of local plans in New Zealand, the methodology can be used by city and county planning agencies in the U.S. and elsewhere.
