The 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, project report, and data layers for the project.
Also listed in the table below under the subheading of "Ecology data" are the results of using the data in the report to identify basins which exceeded 40% total impervious area as of 1991.
