High resolution change detection using 1-m aerial imagery was used to assess shoreline changes involving tree canopy removal and new impervious surfaces along the 4,000 km of Puget Sound shoreline. The Shoreline Management Act of 1971 designates shorelands as the area within 200’ of the ordinary high water mark. This study reviewed 2,950 mapped change locations which were within or crossed the 200’ line with regard to the change within the 200’ line. These changes were compared to those within the 200’-400’ and 400’-600’ bands. This study assessed area, canopy loss, impervious surface gains and change due to natural processes, principally landslides along the shore. Results and data access will be provided.

This abstract is part of a land cover, wetland, and change mapping session which include the following 4 authors: Nate Herold, Meghan Halbisky, Ken Pierce, and Suzanne Shull.
