[1] The school serves primarily those students living north of the Snohomish River (nearby Glacier Peak High School, serving those students living south of the river).

These changes removed the last vestiges of 'old' Snohomish High School, making the building completely modern.

Among the changes made to the B building were the removal of its decades-old fixed wooden bleachers and over-painting of many student-painted murals from the 1960s and earlier.

In an attempt to curb overcrowding, the C building was constructed and opened in 1999, adding ten more classrooms.

As the school became more crowded, it received a grant to remodel the campus, tearing down the B building was a major change.
