Building from previous datasets and analyses, this collection of shoreline parcels throughout Snohomish County have scores related to their vulnerability to sea level rise, along with intermediate calculations and classifications related to each parcel. These data are part of the Prioritizing Sea Level Rise Exposure and Habitat Sensitivity Across Puget Sound project and can be used in combination with other related marine and nearshore datasets to aid restoration prioritization.

Project parcel layer.
Rogers and Cooke, 2012
Coastal parcels in this study are derived from Beach Strategies (Coastal Geologic Services, 2017), which were initially obtained and updated from the Washington Statewide Parcel Database (Rogers and Cooke, 2012). The parcel layer was subsequently expanded from the Beach Strategies layer to include parcels that were either 200 FT from the ShoreZone shoreline (WDNR, 2001) or encompassed elevations of 30 FT or less (based on Tyler et al., 2020) and were hydro-connected to Puget Sound. We also treated the Ballard Locks as a complete topographic boundary to water inundation, which was not captured in the topobathymetric DEM, and therefore manually excluded all parcels past the locks along Lake Union and Lake Washington that were shown to be hydro-connected to Puget Sound within the study area (extent: North: 1,367,576.790880ft, East: 1,285,327.222625ft, South: 531,348.435124ft, and West: 964,628.154378ft).

The wave height data from PNNL (Yang et al., 2019) was interpolated from points to a raster using the ArcGIS geoprocessing Inverse Distance Weighted (IDW) technique with a cell size of 200 FT. The highest wave height cell value within each parcel was chosen as the input for this analysis and assigned to each parcel. This was accomplished by first using the Zonal Statistics tool with the parcel layer as the input feature, the interpolated wave height layer as the input value raster, and the statistics type set to maximum. This outputted a raster layer with only the maximum wave height cell within each parcel. Next, we used the Raster Calculator to determine which cells correspond to the highest elevation found within each parcel with the following conditional statement: Con(“HsFT_IDW”== “Max_Hs_Zonal_Stats”, “HsFT_IDW”)
Then the Raster to Point tool was utilized to turn the output raster from the previous step into a point feature class. Finally, the max wave height value was assigned by using the Spatial Join tool with the parcel layer as the target feature, the join feature as the point layer from the previous step, one to one join operation, and the match option being “closest geodesic.”
