In our newest edition of the Cascadia Scorecard (released yesterday), we examine one of the most important trends in the region: sprawl. It’s an area where there’s been a surprising reversal of fortune. Oregon, long a regional and national leader in smart growth, is losing its lead.

According to a new Sightline analysis, in the Portland metro region alone more than 2,000 residential applications for Measure 37 waivers were approved. Together, these claims could add nearly 14,000 housing units and, based on prevailing rates of occupancy, up to 36,000 new residents outside of growth boundaries.

Such poorly planned sprawl has not been typical of Oregon. The state has a well-deserved reputation for successful growth management; and in every previous edition of Cascadia Scorecard — not to mention numerous other Sightline studies—we’ve highlighted Oregon’s success at curbing sprawl and preserving farms and forests.

In fact, in the very first edition of the Scorecard, in 2004, we specifically contrasted ex-urban residential sprawl in Clark County, Washington (home to Vancouver, WA) to the Oregon counties of metro Portland. The difference was profound.

    In just two years of Measure 37 enough claims were approved in the greater Portland area to potentially result in nearly as much low-density, exurban sprawl as Clark County, Washington, endured in the entire decade of the 1990s.
