Layer name: CITY_3CO_UNINC
Subject category: admin
Title: Incorporated areas of King; Snohomish; and Pierce Counties; plus Unincorporated Areas
Feature Count: 98
Feature Type: Polygon
Abstract: Expanded layer built on CITY_3CO_AREA., CITY_3CO_UNINC_AREA is a compilation of city jurisdictional information from three counties: King, Pierce and Snohomish, plus the unincorporated areas in each of the three counties. Uses the best available information from each of the 3 counties to produce the composite product for the jurisdictional areas and assumes the areas outside of the jurisdictions to be unincorporated. Updated whenever changes are made to any one of the source data sets. For King County this will be whenever CITY_AREA (parent is CITY_ANNEX) is updated to Spatial Data Warehouse. Pierce and Snohomish updates are shared with King County on quarterly to semi-annual basis. Updates are made so that the King County portion of this composite is synchronous with the information in the master King County jurisdiction layer.
Purpose: Representation of the jurisdictional areas (i.e., cities) in the three county area plus the unincorporated areas in each county. Useful for general cartographic, analysis and query of jurisdictional and unincorporated areas. Even though this layer is built from and kept current to the contributing sources, users may wish to use the separate source data layers when working in a more limited area to take advantage of any information or functionality not transferred to the composite. Further, minor spatial adjustments have been applied to Snohomish and Pierce county city layers to improve their fit with the King County data, thus modifying these slightly.
