Jonathan Fink, a geographer affiliated with Portland State University and the University of British Columbia has posted an article entitled "Cascadia Showcases How a Coordinated Corridor Strategy Can Reinforce Urban Innovation", at the Meeting of the Minds blog. The article describes efforts to share innovation in managing urban growth, transportation and climate change amongst across three metropolitan areas of Cascadia--two n the northwest of the USA (Portland, OR and Seattle, WA) and one in the southwest corner of Canada (Vancouver, BC). It will be interesting to see if anything significant results from this effort to share innovation.
