This project assesses the extent of the relationship between mixed-use zone comprehensiveness (as gleaned from municipal land use ordinances) and measures of walkability. The primary hypothesis is, controlling for city population size and SES, the higher mixed-use zone comprehensiveness (i.e. adherence to the American Planning Association’s model mixed-use zone), the higher its walkability. The unit of analysis is approximately 180 Mixed Land Use Zones in 25 California cities (with populations of 50,000 or above).
Zoning laws that mix residential units with commercial and public/civic destinations have the potential to increase walkability. The study finds that significant relationships exist between the range and precision with which the zoning ordinances have been written and the mixture of walking destinations that result within the areas.
