Richland, Washington started as a sleepy agricultural community, nestled alongside the Columbia River. In 1942, the Federal government saw Richland’s remote location, abundant water supply and mild weather as the right combination it needed. At that time, the government took over the land and used it to build the country’s first nuclear reactor on the Hanford Site in 1943. Almost overnight, the population of Richland boomed from about 300 to more than 25,000 when it became a housing development for workers at the Site. It was a closed city, and only government-approved workers were allowed in. Richland’s alphabet houses were designed to accommodate the growth in population at the Hanford Site during World War II and the cold war. Each housing design was assigned an alphabet letter designation and included apartments, dormitories, duplexes and single family homes. As you drive and look around the neighborhoods today, you will see that  these alphabet houses still exist.

In 1958, Richland incorporated and became a self-governed, open city. The last production reactor at Hanford shut down in 1987. Since then, the facility has been dedicated to environmental cleanup, science and technology, and continues to employ many current residents of the Tri-Cities, which include neighboring Kennewick and Pasco. Today, the area is rich in science and technology, as well as recreation, wine production, and education.

Originally, there were only three small churches in Richland, the largest being Community Methodist Church with 138 members. In the 1940’s, the various denominational leaders determined that their efforts would be better served if they consolidated into one. From that day forward all new churches established in Richland would be called United Protestant Churches as they represented the unified work of eleven cooperating denominations, working together for the good of all and for the cause of Christ.

As the area grew because of the nuclear project, the need for churches increased, and in 1947, the American Baptists were sponsors of a second church in Richland, which became known as Southside United Protestant Church. Southside United Protestant Church was the
first non-commercial organization to break ground in the new village of Richland. The first services of the new church were held on Easter Sunday, 1949. This current sanctuary was built in 1968, and the facility was remodeled in 1978 to expand the facilities and education wing.

Today, Southside is a thriving church under the leadership of Pastor Jim Amend, who came to Southside in 2000. The facility not only houses our combined traditional/contemporary Sunday morning service, but numerous activities for the church family and others who use our facility.
