In 2001 the Northwest Environment Watch (now Sightline Institute) contracted the Community and Environment Spatial Analysis Center (CommenSpace) to conduct an analysis of change to population density and impervious surfaces in Portland, Seattle and Vancouver.  Chris Davis, Tim Schaub and I developed a series of metrics and analysis methods used to support the Northwest Environment Watch's assessment of smart growth and pavement presented in their book This place on Earth 2002.  Measuring what matters.

Smart growth, population density and impervious surfaces in three Northwest cities: Portand OR, Seattle WA and Vancouver BC.
