During construction, classes were held at Fruitland Elementary School, under the direction of Principal Ron Williamson.

The school's main complex, divided into wings A through G, was designed by the architecture firm Hammel, Green and Abrahamson of Minnesota; Joe Lavernier Construction of Spokane was the general contractor.

Southridge also has one of the best engineering technology programs in the state, led formally by Jim Hendricks, who was invited to join Tri-Cities STEM School, Delta High, in 2009.

Its material science course offers the chance to create a sterling silver ring and a personal piece of stained glass, both designed by the students.

Former Southridge student Danica Lyn Stewart achieved acting success in her adult life and can be seen on NBC's daytime soap Passions.

Football and soccer games are played at Neil F. Lampson Stadium, which is located on the grounds of Kennewick High School.
