City and county governments offer a variety of services, incentives and tools for historic preservation.  Local governments that establish an historic preservation program meeting federal and state standards can become Certified Local Governments (CLGs).  Following is a list of the CLGs in Washington State.  For contact information on those without web links, consult a list of program participants at Washington's Department of Archaeology and Historic Preservation.
