For this project, Jesse and I explored the Portland Urban Growth Boundary, the line Metro draws around the Portland Metro Area to demarcate the extent of near-term urban growth. The boundary is designed to contain sufficient land for 20 year growth projections, but has nevertheless come under attack for artificially limiting growth of housing and job supply, thereby driving up the cost of housing within the region. We investigated both the relation of housing prices to the UGB in the Portland metro area, and analyzed narratives to assess the opposing claims about housing prices and the UGB. We conducted the first portion of this analysis through GIS mapping of median home values by census tracts in the tri-county region (Multnomah, Clackamas, and Washington counties), overlaid with the UGB; we then classified each of the census tracts as inside or outside the boundary, and found the difference in means of the two groups. For the second portion of the analysis, we gathered several sources supporting or opposing the UGB, and parsed out the narratives told in relation to the UGB and urban planning in Portland in general. We analyzed the place and function of claims about housing prices within their arguments, and traced out how the explanatory frameworks diverged according to the perspectives we named “market narratives” and “planning narratives.” Click through the menu at the right to check out our investigation.
