Request #18-795

I’m doing some research on a site on Mercer Island and came across the PDF of your Mercer Island Landslide Hazard Assessment map on the city website. Would you be able to provide information on the sources of the “Identified Landslide Locations” data? It looks like those locations are “areas of historic failure or that have been documented on published maps”.


Or, if you could provide the referenced “Read Me" document or the digital version of that layer I would really appreciate it.
