Wetlands

This dataset was composed in 2006 with the initiation of the Island County Critical Area Update. During the process wetland information was compiled from three main resources: The National Wetland Inventory Dataset, digital wetland delineations performed by Pentec in 1998, and county wetland files. Approximately 750, 600, and 400 shapes respectively were merged together to form this single dataset. Many of the same wetlands were found in each dataset thus when combined the total number to wetlands was approximately 1000. Since 2017 Planning staff have been modifying this layer with site review and submitted PCAD data. Accuracy of this layer is unknown. Some polygons appear to very consistent with aerial photography, while other polygons appear to be shifted from the actual wetland by as much a 200+ feet.
