Geological Hazard Areas

Data format: Shapefile

File or table name: geohazard

Coordinate system: Lambert Conformal Conic

Theme keywords: stability, soils

Abstract: The GEOHAZARDS feature class is a union of the DNR & Natural Resource Conservation Service's (SCS) 1980 Soil Survey for Kitsap County and the soil STABILITY classification from the 1979 "Quaternary Geology and Stratigraphy of Kitsap County" thesis work by Jerald Deeter. The original Stability coverage was obtained by digitizing the "Slope Stability Map of Kitsap County" from the Deeter 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. The DNR/NRCS soil survey mapping project was originally published on paper maps in 1980. The mapped soil delineations were digitized by DNR and transferred into the DNR GIS system in 1998. Spatial accuracy of the original soils coverage is quite good and can be used at medium scales. However, displacement is noticeable in some areas along shorelines and varies in degree. Limitations of this data set are multiplied due to the spatial accuracy and constrains of the originating data layers. 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 Layer is a subselection of the orginal data set, the selection criteria used on the attributes varied. For Geologic Hazardous Areas the selection was- "STABILITY = 'U' OR STABILITY = 'Uos' OR STABILITY = 'Urs' AND SLOPE_MIN >= 30". For Geological Areas of Concern with slopes >15% w/springs & groundwater the selection was- "IDENTIFIER = 3 OR 16 OR 25 OR 41 OR 53 OR 57 OR 61" For Geological Areas of Concern with Highly erodible/potential of high erodibility the selection was- "STABILITY = 'S' AND IDENTIFIER = 3 OR 10 OR 17 OR 21 OR 25 OR 26 OR 27 OR 31 OR 46 OR 48 OR 53 OR 54 OR 9 OR 13 OR 16 OR 20 OR 30 OR 36 OR 41 OR 47 OR 57 OR 61" For Geological Areas of Concern with Intermediate Slope Stability the selection was- "STABILITY = 'I'" For Geological Areas of Concern with Unstabel slopes < 30% the selection was- "STABILITY= 'U' OR 'Uos' OR 'Urs' AND SLOPE_MIN < 30" **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. -

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Purpose:
This data set allows analysis of large areas based on stability and soil type attributes and criteria. These can be used to determine area suitability and potential for specific uses, or to plan the management needs for those uses or other uses. Detailed soil attributes are incorporated in the SCS_SOILS_POLY attribute table that may be joined to the STABSOIL attribute table using the "IDENTIFIER" field. The SCS_SOILS_POLY is available for download through the Kitsap County FTP site or on the Kitsap County GIS Data CD. The Department of Agriculture Natural Resources Conservation Service "Soils Survey of Kitsap County" publication is recommended for reference, and is available on-line at www.or.nrcs.usda.gov/pnw_soil/washington/wa635.html. **This data cannot and may not be used for or relied upon for site-specific evaluations, nor as a substitute for a field survey.
