In 2001, the company moved its headquarters from Portland to a site in an unincorporated part of Washington County, in the Cedar Mill area and just outside the Beaverton city limits. The site on NW Science Park Drive has a Portland mailing address, but is not in Portland. In 2007, City of Portland officials attempted to convince Columbia Sportswear to move back to Portland, but the company ultimately rejected the idea due to the increased corporate tax burden such a move would entail and decided to expand its existing headquarters instead.
