Somerville officially organized on March 19, 1913 with a commissioner form of government. Those who held office included Mayor Casper Landolt, Councilmen R.A. Brantley, Jr.; R. L. Meeks, and City Secretary W. H. Lynch. In April 1915, Mr. Lynch became Marshall and was paid $75.00 a month. Mr. E. R. Reynolds then became City Secretary being paid $60.00 a month.

As the town of Somerville grew, the need for expansion of the school system also became apparent. The public school started as a 3 room building at the corner of 9th street. In 1905, with the help of Mr. Landolt, the first brick building was constructed at the present site. The first graduating class consisted of 3 boys and 2 girls in 1909. In 1920 indoor plumbing was added to the school but woodburning stoves were used until gas boilers were added in 1950. The Stone Gym (now the Yegua Center) was erected in 1939, the present Jr. High was built in 1969 and the existing High School was built in 1979-80.
