Thurston GeoData Center N/A HYDRIC Classified as a hydric soil. Features with an NRCS hydric rating greater than 33 considered hydric, per CPED decision on 1/6/2026. "Hydric" means that all components listed for a given map unit are rated as being hydric. "Predominantly hydric" means components that comprise 66 to 99 percent of the map unit are rated as hydric. "Partially hydric" means components that comprise 33 to 66 percent of the map unit are rated as hydric. "Predominantly nonhydric" means components that comprise up to 33 percent of the map unit are rated as hydric. "Nonhydric" means that none of the components are rated as hydric. The assumption here is that all components of the map unit are rated as hydric or nonhydric in the underlying database. A "Not rated or not available" map unit rating is displayed when none of the components within a map unit have been rated. Thurston GeoData Center 1 Yes Thurston GeoData Center 0 No Thurston GeoData Center EROSION Susceptible to erosion, based on K factor and slope (greater than 15%). Low (advisory) erosion soils have a K factor lower than 0.25. Moderate (advisory) soils have a K factor between 0.25 – 0.35. High soils have a K factor greater than 0.35. Thurston GeoData Center 1 Low (advisory) Thurston GeoData Center 0 Moderate (advisory) Thurston GeoData Center 3 High Thurston GeoData Center GlobalID A field of type UUID (Universal Unique Identifier) in which values are automatically assigned by the geodatabase when a table row is created. The GlobalID field is necessary for maintaining object uniqueness across replicas. All feature classes and tables participating in one-way or two-way replication must contain the GlobalID field. This field is not editable and is automatically populated when it is added for existing data. A GlobalID is often used as the primary key in the database table, but it is different than the typical OBJECTID or FID field. A GlobalID is often created in ArcGIS by right-clicking in the ArcCatalog tree and choosing "Add Global IDs". It can be applied to standalone feature classes or tables or applied to an entire feature dataset. Wade, T. and Sommer, S. eds.
