Benton County was created on December 23, 1847 by an act of the Provisional Government of Oregon.[3] The county was named after Democratic Senator Thomas Hart Benton of Missouri, an advocate of the doctrine of Manifest Destiny and the belief that the American government should control the whole of the Oregon Country. At the time of its formation the county included all the country west of the Willamette River, south of Polk County and running all the way to the California border in the south and the Pacific Ocean in the west.[4]

The county was created out of lands originally inhabited by the Klickitat, who rented it from the Kalapuyas for use as hunting grounds. All aboriginal claims to land within Benton County were ceded in the Treaty of Dayton in 1855. Portions of Benton County were taken to form Coos, Curry, Douglas, Jackson, Josephine, Lane and Lincoln Counties, leaving Benton County in its present form.

The city of Marysville, later renamed Corvallis, was made the county seat in 1851. The city briefly was the capital of Oregon.[5] In 1862 Corvallis became the site of the Oregon State Agricultural College, known today as Oregon State University.


According to the U.S. Census Bureau, the county has a total area of 679 square miles (1,760 km2), of which 676 square miles (1,750 km2) is land and 2.7 square miles (7.0 km2) (0.4%) is water.[6] It is the fourth-smallest county in Oregon by land area and third-smallest by total area.

Since 1972, Benton County has been an Oregon "Home Rule" County, meaning that the citizens have full control over the county charter, rather than using a standard constitution issued by the state.[14] The voters have chosen to eliminate the traditional elected county offices of Assessor, Treasurer, Surveyor, Justice of the Peace, and Clerk. Currently, they only elect three County Commissioners and a Sheriff.[15][16]

The three current Benton County Commissioners are Chair Annabelle Jaramillo, Vice Chair Linda Modrell, and Jay Dixon. They are all members of the Democratic Party and have served since 2001, 1999, and 2001; respectively. Jaramillo and Dixon's current terms expire in January 2017, while Modrell's is up in January 2015.[16][17][18][19] Linda Modrell has not yet announced if she will seek reelection in the November 2014 General Election. Local Democrat Quintin Kreth is the only candidate to have filed for the seat thus far.[20][21]

The current Benton County Sheriff is Scott Jackson. He was appointed to the office as of July 1, 2013 to fill the remainder of the term of retiring sheriff Diana Simpson, the first elected female sheriff in Oregon. He faces reelection in the November 2014 General Election.[22]


Along with Oregon State University, agriculture, lumber, wood products, and some printing technology research and development form the economic base of the county. A substantial portion of the nation's research in forestry, agriculture, engineering, education and the sciences takes place at OSU.
