By the early 1970s, overcrowding at Sylvania High School (now Sylvania Northview High School) had become severe enough that the district was using the old Burnham building as an overflow campus, requiring students to walk between buildings for different classes. In 1973, the school board authorized the purchase of 50 acres on Sylvania Avenue for $180,000 to build a second high school. Southview opened in September 1976. Upon its opening, the original Sylvania High School was renamed Sylvania Northview High School to distinguish the two campuses.
