  1. This plan uses the term “transit communities” to refer to the combination of Portland’s station areas (the half mile radius around its light rail and streetcar stops), and the quarter mile around its quality bus corridors (divided into segments based on shared characteristics). To the extent possible the authors have analyzed data and provided maps for both station areas and bus corridors; however in some cases data was only available for station areas.

  14. CTOD has found it challenging to collect meaningful data that measures market strength on a regional basis. Often the only source of information available at this scale is assessor’s data, which is of variable quality from city to city or county to county. Given that it is based on actual market transactions, sales data represents the most reliable source of information to determine relative variation in market strength across a region.

  18. The categories of investment strategies discussed here collapse categories that are indistinguishable from a funding or staffing perspective (i.e. “participate in community visioning/outreach” and “provide technical assistance with planning efforts”). Additionally, based on current national trends in MPO TOD activities, as well as the critical nature of the investment, “connect local government partners with infrastructure/community development partners,” has been made more direct, i.e. “infrastructure and public amenity improvements”. This assessment of need is based only on the number of station areas that require each type of assistance, not the actual magnitude of need within each station area (i.e. via engineering survey analysis).
