Richland, WashingtonRichland is a city located in Benton County in southeastern Washington, at the confluence of the Yakima River and the Columbia River. As of the 2000 census, the city had a total population of 38,708. Founded in the early 1900s, Richland was a sleepy little farm town until the US Army decided to turn it into a bedroom community for the workers on its Manhattan Project at the nearby Hanford Nuclear Reservation. The population sprang from 300 to 25,000 almost overnight in July and August of 1943. (Richland contains many reminders of its past; the high school's sports teams are called the Bombers - complete with a B-52 logo, a number of the streets are named after generals in the US Army, and a local museum features exhibits of nuclear technology.) After the end of World War II Richland continued to be a center of production and research into nuclear energy.
Richland, Pasco and Kennewick are collectively referred to as the Tri-Cities, Washington.
