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><P><SPAN>Spatial Reference: NAD_1983_HARN_StatePlane_Washington_South_FIPS_4602_Feet</SPAN></P><P><SPAN>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.
