South Bay Union High School District

It was established circa 1905. Redondo Union High School was the district's first high school. Torrance High School was part of this district only for the 1947-1948 school year, as California law prevented the newly-formed Torrance school district from immediately controlling high schools. The following year it became the Torrance Unified School District and took control of Torrance High. In 1991 the elementary school districts within South Bay Union HSD had plans to unify into a single K-12 school district. In spring 1991 the enrollment was down to 2,900. For the 1991-1992 school year the district was facing a budget shortfall of $1.4 million dollars and was considering closing either Mira Costa High School or Redondo Union High School. == Schools ==

; Open at the time of the district's dissolution • Mira Costa High School (Manhattan Beach) • Redondo Union High School (Redondo Beach) • Pacific Shores Continuation School - Closed June 30, 1993 ; Left the district prior to dissolution • Aviation High School (Redondo Beach) - closed in 1982 • Torrance High School (Torrance) - Was in the Redondo Beach Union HSD for the 1947-1948 school year, after it left the Los Angeles City High School District and before it joined the Torrance Unified School District. At the time in California law a newly formed school district could not immediately take high school facilities, so Torrance High joined South Bay Union HSD for the one year wait. == References ==
