Jefferson County, WashingtonThis layer depicts areas designated as soil types having severe or very severe building limitations for dwellings without basements by the Soil Conservation Service. Polygons included in the layer were selected from the SCS Soils source coverage for specific soils types identified in the published SCS manual. In addition, properties with known slide problems and properties with areas in excess of a 15% slope have been added (categorically 15%-30%, 30%-60%, >60%). Finally, parcels that had active slides in the winter of 1998/1999 as identified by the building official have been added and are represented by a "5" in the keysoils field. Special conditions or standards may apply to development in areas subject to landslide hazards. Details should be obtained from the Department of Community Development.This is a composite layer produced from the SCS Soils source coverage for soils types in Eastern Jefferson County, the Department of Ecology Coastal Zone Atlas of Jefferson County, and a review of topographic contours indicating steep slopes. This composite layer does not give detail attributes, but it does give an attribute with a rating factor which is a weighted probable problem rating based on severity of slope.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/553e2a3518124f83acaa8fe46a7244f9_5engJefferson County Washington Open Data SitePublicLandslide Hazard [Washington (State)--Jefferson County]Web servicesWashington (State)--Jefferson CountyWashington (State)Last Modified: 2017-05-15
