Boundaries of the seven King County Unincorporated Community Service Areas (CSA). The Community Service Areas were designed to encompass the unique features of King County unincorporated communities. They are intended to bring together communities of interest within a geographic setting for outreach and engagement by King County staff. The layers show what CSA community members live in as well as what CSA existing and potential projects occur in.

This layer contains critical areas & their buffers on specific parcels that have undergone Critical Area Review.Critical Areas are lands with natural hazards or lands that support certain unique, fragile or valuable resource areas. Lands designated by King County as critical include areas at high risk for with steep slopes, erosion, landslides, earthquakes, flooding; coal mines; or aquatic water features such as wetlands or lands adjoining Aquatic Areas such as streams, rivers and other water bodies.Critical Area Buffers are areas adjacent to a critical area and are also restricted from specific building and development activities.

County boundaries for Washington state, with Puget Sound removed, showing coastal shoreline. Also as KINGSH for King County only.

Location of painted targets, as point features, used during aerial imagery photo acquisition. Data comes from multiple sources, and various vintages. Older vintage locations may not be visible in newer imagery, especially imagery greater than 1-foot resolution. Locations contain x,y and z coordinates.

King County Real Property. Parcels owned by King County for the multiple category types, and the following use codes: County Used, Financial Investment, Interim Holdings, Social Investment, Surplus. Includes assessed value and acquisition dates.

Transportation features including rail, trails and pedestrian walkways with address ranges & names derived from digital orthophotography and GPS.

The King County Sensitive Areas Ordinance (SAO) defines coal mine hazard areas as those areas directly underlain by or adjacent to or affected by abandoned coal mine workings such as adits ( a nearly horizontal entrance to a mine), drifts (a secondary passageway between two main shafts) tunnels, or air shafts.

City data showing pending annexations and annexation history. This will be the parent of city_kc_area and city_area.

Authoritative Points-of-Interest layer for King County. Contains over 45 different domain classes showing locations and names for a range of different features. Some classes of features are extensively documented (such as school sites and hospitals) while other classes represent a selected set of all the features of that type (such as hotels and shopping centers). Each feature is represented by a single point describing the centroid of the feature. Multiple points for a single XY coordinate may exist if more than one domain is represented. In other words, a single feature may represent a hospital, but that same point may be represented by another feature (i.e., record) described as a Public Health Clinic.

A spatial tiling index designed for storage of file-based image and other raster (i.e., LiDAR elevation, landcover) data sets. An irregular grid of overlapping polygons, each enclosing its respective Public Land Survey System (PLSS) township in an orthogonal polygon minimally encompassing all portions of that township, i.e., minimum bounding rectangle. The amount of overlap between adjacent tiles varies depending on the geometry of the underlying township. Currently extended to include all townships within or partially within King County as well as those townships in the southwestern portion of Snohomish County included within King County's ESA/SAO project area. The name of the spatial index is derived from the acronym (I)n(D)e(X) (P)olygons for (T)ownship-(R)ange, (M)inimum (B)ounding (R)ectangle, or idxptrmbr. Tile label is the t(township number)r(range number)as in t24r02. The meridian zone identifiers, N for townships and E for range is inferred as this index is intended as a local index for ease of use by the majority of users of GIS data. Lowercase identifiers are used for consistency between Unix and Windows OS storage. This index or tile level is the primary user-access level for most LiDAR elevation, orthoimagery and high-resolution raster landcover data. However, not all image and raster data is stored at the tiling level if a given data's resolution does not justify storing the data as multiple tiles.
