County landmark designation and regulation is limited by law to the unincorporated area. In 1995 the county established a regional landmark protection program. Today more than half of the cities contract for landmark services from the county. The cities of Seattle, Mercer Island and Bothell have their own historic preservation programs, but Seattle contracts with the county for archaeological review services. To participate in the county’s regional program, cities must adopt certain sections of the county landmark ordinance by reference, appoint a city representative to the Landmarks Commission, and provide for design review of any changes proposed to landmark properties. Additional services include preparing nominations, conducting historic resource surveys, and assistance with preservation planning and environmental review. The King County Regional Preservation Program continues to be one of the largest and most unique in the Pacific Northwest.
