Vashon-Maury Island CSA Background

The 2017 Comprehensive Plan update will be focused on the proposed Vashon-Maury Island CSA Subarea Plan. A CSA Subarea Plan is a 20-year, multi-discipline, integrated policy document that applies the countywide goals of the King County Comprehensive Plan to a smaller geographic area.  You can learn more about King County’s CSA Subarea Planning Program, including the schedule for future CSA planning activities in other unincorporated areas, here.

Development of the Executive’s proposed Vashon-Maury Island CSA Subarea Plan was informed by an intensive community outreach process that began in March, 2016.  More information on the Executive’s outreach can be found here.

About the King County Comprehensive Plan

The King County Comprehensive Plan is the guiding policy document for land use and development regulations in unincorporated King County, and for regional services throughout the County including transit, sewers, parks, trails, and open space.

The King County Code (K.C.C. 20.18.030) allows for updates to the Comprehensive Plan on either an annual or a once-every-four-years basis, depending on the scope of the change. The annual cycle allows for minor changes, technical corrections, and land use changes that do not amend the Urban Growth Area. The “four-year cycle” update is considered a major update to the plan and, unlike annual updates, allows for consideration of substantive policy changes and potential revisions to the Urban Growth Area.

The current plan is the 2016 Comprehensive Plan, which was adopted by the King County Council on December 5, 2016.  The 2016 Comprehensive Plan was the fifth major update to the King County Comprehensive Plan.
