Richland is a city in Benton County in the southeastern part of the State of Washington, at the confluence of the Yakima and the Columbia Rivers. Along with the nearby cities of Pasco and Kennewick, Richland is one of the Tri-Cities, and is home to the Hanford nuclear site and unlimited hydroplane racing on the Columbia River. Agriculture is important in the Richland area; the Tri-Cities area of the Columbia Basin grows excellent produce. Richland hosts an important food processor, ConAgra/Lamb-Weston, which processes potatoes and other foods.
The production of wine in the lower Columbia Basin has become one of the area's main industries. Richland lies at the center of a viticulture area which produces internationally recognized wines in four major Washington appellations and serves as a center for wine tours. The Columbia Valley appellation which surrounds Richland contains over 7,000 hectares planted with wine grapes. Richland is home to the largest cold-storage facility on Earth—which is also one of the largest buildings on Earth by volume.
