County-wide vulnerability index for Thurston County Stormwater division. Indicators include: impervious surface area (Impervious); percent of parcels with structures in flood zone (PctFldPlai); percent of land area in flood zone (PctFldHz); percent residential parcels (PctResPrcl); percent commercial parcels (PctComPrcl); and percent industrial parcels (PctIndPrcl). <\/SPAN><\/P>

Percent imperviousness within each Thurston census block group (Impervious) determined using Zonal Statistics as table where NLCD 2019 developed impervious data (mask extracted by Thurston census blocks) was the input value raster and 2018 Census block groups from US Census Bureau was the zone data. The 'mean' statistic represents percent imperviousness within each census block.

Percent of parcels with structures in flood zone (PctFldPlai) was determined using FEMA flood zone data and Thurston parcels from Thurston Geodata. Land-only parcels were excluded from this analysis.

Percent of land area in flood zone (PctFldHz) was determined using FEMA flood zone data. Retrieved 12/23/21 from https://msc.fema.gov/portal/downloadProduct?productTypeID=NFHL&productSubTypeID=NFHL_COUNTY_DATA&productID=NFHL_53067C <\/SPAN><\/P>

Percent industrial parcels (PctIndPrcl) was determined using Thurston parcel data from Thurston Geodata. Retrieved 12/22/21 from https://gisdata-thurston.opendata.arcgis.com/datasets/thurston-parcels/explore?location=46.971500%2C-122.701000%2C10.92<\/SPAN><\/P>

Each category was normalized and a z-score was calculated. Each indicator was then assigned a z-class (ZclasImpv, ZClasFldPl, and ZClasFldHz) according to its z-score. Z-scores between 1-2 received a z-class of \"1\" and z-scores greater than 2 received a z-class of \"2\". <\/SPAN><\/P>

Z-class scores were aggregated to obtain a composite vulnerability index score (CompVuln) with a potential range of 0-6. <\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "copyrightText": "Multi-Resolution Land
