Subarea Planning

Updated June 10, 2024

The King County Comprehensive Plan (KCCP) calls for local subarea planning. King County has divided its Unincorporated Areas (both Urban and Rural) into Community Service Areas (CSAs). The Area Council’s territorial area falls within the Greater Maple Valley-Cedar River (GMV/CR) Community Service Area (CSA).

The following CSA Subarea Plans have been completed in the last several years: Vashon-Maury Island; Skyway-West Hill; North Highline; and Snoqualmie Valley/NE King County. After the completion of the GMV/CR CSA Subarea Plan the following will be started (date shown): Fairwood  Potential Annexation Area (PSS) (2025); Bear Creek/Sammamish (2028); Southeast King County (2029); Four Creeks/Tiger Mountain (2033); East Renton PAA (2034); and Federal Way PAA (2035). Please see: King County Unincorporated Area Subarea Plans.


Starting in the fall of 2024 King County will be undertake a major update to the GMV/CR CSA Subarea Plan (supersedes the former Tahoma-Raven Heights Area Plan).
