The 2005 Western Washington Land Cover Change Analysis project was to provide land cover data for Western Washington for a 1991 time frame and a comprehensive analysis of change in land cover, impervious surface, and forest canopy for all of Western Washington between 1991 and 2001.
Listed below is the final shapefile (“Western Washington Counties”), Sanborn project report, and 1991, 1996, and 2001 data layers for the project. In 2009, Ecology contracted with NOAA to provide analysis of land cover for 1986 and 2006. Those data layers have been added to the table below.
Also listed in the table below under the subheading of "Ecology data" are the results of using the data provided by NOAA to identify basins which exceeded 40% total impervious area as of 1986.

The data files are all available via anonymous FTP: ftp://www.ecy.wa.gov/gis_a/landcover.
