Census 2010 Redistricting
The Washington State Redistricting Commission is charged with adjusting the lines of congressional and legislative district boundaries after each decennial census. Given Washington State's growth over the previous decade, Washington will have an additional congressional district for the 113th congress. The third district will need to lose 106,894 people in the redistricting process in order to meet the ideal population of 672,454. On September 13, 2011, the four voting commissioners on the Redistricting Commission submitted draft proposals for the congressional map. All four draft proposals left the entirety of Lewis, Wahkiakum, Cowlitz, and Clark Counties, and all or most of Skamania county in the 3rd district. In addition, each proposal added population from one or more of Pacific, Thurston, Pierce, or Klickitat counties.
The final approved map for the 3rd district includes the entirety of Klickitat, Skamania, Clark, Cowlitz, Wahkiakum, Pacific, and Lewis counties, with the extreme southern part of Thurston county south of highway 12, Washington State Route 507, and the Vail Cut Off Road.
