History of Richland
Located at the confluence of the Columbia and Yakima rivers in southeastern Washington, Richland is a community shaped by thousands of years of history, innovation, and growth.
Long before the city was established, Indigenous peoples lived, traveled, and gathered throughout the region. For more than 11,000 years, the area now known as Richland supported Native communities who fished the Columbia and Yakima rivers, hunted local wildlife, and harvested native plants. The Village of Chemna, located near the mouth of the Yakima River, served as an important gathering place for Sahaptin-speaking peoples, including the Wanapum, Walla Walla, and Yakama.
European-American settlement began in the late 1800s as families established homesteads along the rivers and fertile farmland. In 1892, Nelson Rich and Howard Amon founded the community that would become Richland. The town grew steadily as an agricultural center and was officially incorporated on April 28, 1910.
Richland’s history changed dramatically during World War II. In 1943, the federal government selected the area as part of the Manhattan Project, a top-secret effort to develop the world’s first atomic weapons. The original town was acquired by the federal government and transformed into a planned community to support the Hanford Site workforce. Thousands of workers and their families arrived from across the nation, and Richland quickly evolved from a small farming town into a vital center of scientific and industrial activity.
Following the war, Richland continued to grow alongside the Hanford Site and the region’s expanding scientific and research community. In 1958, residents achieved self-governance when Richland incorporated as a chartered First Class City, marking the beginning of a new chapter of local leadership and community development.
Today, Richland is a thriving city known for its exceptional quality of life, scenic riverfronts, abundant parks and trails, nationally recognized research institutions, and diverse economy. While its history remains deeply connected to agriculture, science, and innovation, Richland continues to look toward the future through investments in education, technology, recreation, and economic development.
As one of the Tri-Cities, Richland has grown from a small riverside settlement into a vibrant community of more than 65,000 residents, while preserving the stories, places, and people that helped shape its unique identity.
