In 1908, the United States Reclamation Service (USRS) constructed the Sunnyside Headquarters Building to serve the Sunnyside Division of the Yakima Irrigation Project. Presently, the building stands as the most intact remaining structure associated with early twentieth century efforts to irrigate the Yakima Valley. The Sunnyside Canal irrigation system was purchased by the USRS in 1906, and the Sunnyside Division became the first division of the nearly 500,000 acre Yakima Project. Currently owned by the Sunnyside Community Hospital, the building faced demolition in order to clear the way for construction of a new student health center. Responding to community concerns over the proposed demolition, the hospital, working with the school district, identified a new site for the health center. The reprieve may only be temporary, as other proposals for the site may soon be considered. The Sunnyside Historical Museum is currently working with the hospital on plans to relocate the Reclamation Building to a nearby site in the downtown area.
