Because of the cost of providing city services, low-density residential neighborhoods represent a net revenue loss for municipalities. Because vehicle-license revenue is no longer used to subsidize unincorporated areas, these neighborhoods have become increasingly orphaned.

In April 2004, the City Council voted to defer a decision on Mayor Nickels' proposal to designate the West Hill and North Highline neighborhoods, part of unincorporated King County, as potential annexation areas (PAAs) for at least a year. Because of the tax revolt that took place in Washington in the late 1990s and early 21st century, the county's budget has been reduced and the county has said it is unlikely to be able to maintain adequate levels of funding for urban services in unincorporated areas.  The nearby city of Burien, however, has issued a 2004 draft report for its own annexation of all or part of North Highline.

North Highline, which adjoins SeaTac, Burien, and Tukwila in addition to Seattle, consists of the Boulevard Park neighborhood and part of White Center. West Hill, which abuts Tukwila and Renton as well as Seattle, consists of Skyway, Bryn Mawr, Lakeridge, and Earlington. Its population is 32,000.

On December 11, 2006, the Seattle City Council agreed to designate North Highline a "potential annexation area".
