was annexed 1921; some land near the river in this area remains part of unincorporated King County. In 1910 Georgetown was the last of this sequence of small incorporated cities and towns to be annexed to Seattle before the 1954 annexation of Lake City. The following previously incorporated cities and towns were annexed by Seattle. This list is in order of annexation. Other areas annexed to Seattle, were unincorporated before annexation. Examples of the latter include the northern part of Queen Anne Hill, the University District, and the northern area of the city that were once part of then-unincorporated Shoreline. Town of South Seattle, incorporated 1905, annexed 20 October 1905. City of Columbia (Columbia City), incorporated 1892, annexed 3 May 1907 Town of Ravenna, incorporated 1906, annexed 15 January 1907 Southeast Seattle—Hillman City, York, and other Rainier Valley neighborhoods except Columbia City—incorporated July 1906, annexed 7 January 1907 Town of South Park, incorporated 1902, annexed 3 May 1907. City of Ballard, incorporated January 1890, annexed 29 May 1907 City of West Seattle, incorporated April 1902, annexed 24 July 1907 City of Georgetown, incorporated 1904, annexed 4 April 1910 Lake City, incorporated township 1949, annexed January 1954 Future 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 Bryn Mawr-Skyway, Lakeridge, and Earlington. Its 2010 population is 15,645. On December 11, 2006, the Seattle City Council agreed to designate North Highline
