Testing the Results of Municipal Mixed-Use Zoning Ordinances: A Novel Methodological Approach

Municipal mixed-use zoning (MUZ) is one public health strategy to create more walkable neighborhoods by reducing the separation of daily activities. This study uses a novel data-gathering methodology to evaluate municipal zoning ordinances in twenty-two California cities in conjunction with the walkability potential of resulting mixed-use zones, to explore the extent to which variations in uses mandated by MUZ ordinances are correlated with variations in walking opportunities. We find that, after controlling for population, socioeconomic status, and zone size, significant relationships exist between the range and precision of uses mandated by MUZ ordinances and the mixture and breadth ofwalking destinations in these zones. The study also demonstrates that analysis of municipal zoning codes and a novel data-gathering methodology yield valid data. The analysis of MUZ ordinances is a significant complement to other approaches to measuring walkability and can be used across cities.
