Comparing apples with apples: How different are recent residential development patterns in Portland and Charlotte?

This paper compares Portland in Oregon and Charlotte in North Carolina to determine if recent residential development patterns in each area are as different as their existing policy framework and regulations might suggest. Using spatial data sets from local sources, we first perform a cluster analysis to develop a typology of census block groups based on built-environment characteristics. This derived typology is coupled with data on single-family residential construction for both study areas to assess the degree of similarity. We find that Portland and Charlotte present very different residential development outcomes in recent years. More specifically, single-family residential development has occurred most frequently in the inner- and middle-ring suburbs in Portland and most heavily in the urban fringe areas in Charlotte. Potential explanations of the observed difference are offered.
