Columbia County is a county located in the U.S. state of Oregon. As of the 2010 census, the population was 49,351.[1] The county seat is St. Helens.[2] It was named for the Columbia River, which forms its eastern and northern borders.

Columbia County is included in the Portland metropolitan area.

History[edit]

The Chinook and Clatskanie Native Americans inhabited this region for centuries prior to the arrival of Robert Gray, captain of the ship Columbia Rediviva, in 1792. The Lewis and Clark Expedition traveled and camped along the Columbia River shore in the area later known as Columbia County in late 1805 and on their return journey in early 1806.

Columbia County was created in 1854 from the northern half of Washington County. Milton served as the county seat until 1857 when it was moved to St. Helens.

Columbia County has been afflicted by numerous flooding disasters, the most recent in December 2007. Heavy rains caused the Nehalem River to escape its banks and flood the city of Vernonia and rural areas nearby. Columbia County received a presidential disaster declaration for this event.

Economy[edit]

The primary industries are wood products and paper manufacturing, trade, construction and horticulture.[3][4] The extensive stands of old growth timber, which had attracted many of the early settlers to the area, were completely logged over by the 1950s.[5] Second-growth timber provides the raw material for local lumber and paper mills. About half the county's workforce commutes out of the county to work, most to the nearby Portland, Oregon metro area.[6] Columbia County's average nonfarm employment was 10,740 in 2007.[7] The five largest private employers in Columbia County are Fred Meyer, Armstrong World Industries, Wal-Mart, Boise Paper, USIA,[8] and USG.[9]

Government[edit]

The county is governed by an elected board of three commissioners. Each commissioner is elected to a term of four years. Other elected officials include the Sheriff, County Clerk, District Attorney, Treasurer, Surveyor, Assessor and Justice of the Peace.

Geography[edit]

According to the U.S. Census Bureau, the county has a total area of 688 square miles (1,781.9 km2), of which 657 square miles (1,701.6 km2) is land and 32 square miles (82.9 km2) (4.59%) is water.[10]
