Kitsap County GIS"Quaternary Geology and Stratigraphy of Kitsap County", - Jerald Deeter 1979 thesis (WWU). The original slope stability coverage was obtained by digitizing the "Slope Stability Map of Kitsap County" from the Deeter 1979 thesis. This work was performed by Kitsap County GIS. Accuracy and precision standards used for digitizing are unknown. Spatial accuracy is fairly good at small scales, however, accuracy diminishes as the scale increases. Horizontal displacement is quite noticeable along shorelines when comparison of physical features such as estuaries and peninsulas are observed along side imagery. Displacement ranges between 60 to 200 feet at different locations. Limitations of this data set are multiplied due to the spatial accuracy and constrains of the originating data and the digitizing process. This data set is useful for general area characteristics at medium to small scales (on large geographical areas), but not for characteristic determinations at large scales (on small and site specific geographical areas). **This data cannot and may not be used for or relied upon for site-specific evaluations, nor as a substitute for a field survey. - NOTE: The original Deeter work contained an "Io" stability value, which was a subcategory of Intermediate slopes. This subcategory was created and used by Deeter for those Intermediate slopes that were in excess of 30 percent grade which, at the time, had applicable on-site sewage disposal system restrictions per WAC 248-96 (Deeter). As these regulations no longer apply, the "Io" subcategory was removed, leaving all Intermediate slopes under the Intermediate (I) stability value. -ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/0580390aae2342a88feb0dfc2962cb76_0engOpen Data Kitsap County GISPublicSoil Stability from Deeter Survey [Washington (State)--Kitsap County]Web servicesWashington (State)--Kitsap CountyWashington (State)Last Modified: 2025-10-09
