Burien welcomed its new neighbors with billboards, including this one at South 152nd Street and 1st Avenue South, near Highline High School.
Burien passed the state capitol in population on Thursday, April 1, as Burien officially annexed the southern part of unincorporated North Highline.
Burien has jumped up ten spots from the 31s largest city in the state to 21st, passing Olympia. About 14,500 people joined Burien's 31,000 residents.
The city won't be growing anymore in the near future after the City Council decided to delay consideration of annexing White Center and the rest of the remaining unincorporated portion.
Voters in the newly annexed area approved the move to Burien in August by a 55 percent to 45 percent margin.
No official ceremony is planned for Thursday but Burien will hold a welcoming reception before the April 5 council meeting.
Burien staffers have maintained that the addition will be revenue neutral-new tax collections generated from the new neighbors will match the cost of new services to the area.
Burien will receive up to $700,000 per year for 10 years in state sales tax credit for annexing the area.
