Mixed-use developments are one of the means planners use to realize land-use changes required by SB375 to encounter climate change. The mix of land uses is intended to reduce distances between activities. However, for their economic viability, such projects require specialty retail as anchor tenants which draw a special customer base that may be willing to travel far. Consequently, specialty may contradict a mixed-use development's intention to reduce traffic. This research looks into the spatial behavior of the customers of a health-food store that is located at the mixed-use development "Park Place" in Irvine, CA. Using a POS-intercept survey and GIS, the author found that regular health-food shoppers indeed travel significantly farther distances than occasional health-food shoppers.
