Summary


Representation of the jurisdictional areas (i.e., cities) and the unincorporated areas in the three county area as well as the bordering Chelan, Kitsap, and Kittitas counties.

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.

Minor spatial adjustments may have been applied to the surrounding county city layers to improve their fit with the King County data, thus modifying them slightly.

Description


Expanded layer built on CITY_3CO_AREA., CITY_3CO_UNINC_AREA is a compilation of city jurisdictional information and unincorporated areas from six counties: King, Pierce, Snohomish, Chelan, Kitsap, and Kittitas.

Uses the best available information from each of the six 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 of the source data sets.

For King County this will be whenever CITY_AREA (parent is CITY_ANNEX) is updated to Spatial Data Warehouse.

Updates are made so that the King County portion of this composite is synchronous with the information in the master King County jurisdiction layer.
