White Center is an urbanized area of King County that is not incorporated as part of a city. Seattle has been working towards incorporating the area since the mid-2000s. An area south of White Center, known as North Highline, was annexed by neighboring Burien on April 1, 2010. The Seattle city council rejected annexation of White Center in 2009, and a measure to annex White Center to Burien was rejected by voters in 2012. Plans to annex White Center got a boost in March 2016 when the state legislature directed that $7 million go to the city of Seattle if it annexes the area. Completing annexation would require approval by the voters in the area as well as by the Seattle City Council, and would not be completed before 2017.
