The annexations include: The Palos Verdes Peninsula region was formerly in the Los Angeles city district.
However that area seceded effective January 26, 1925, when the Palos Verdes School District was established.
[2] Torrance was originally in the district; Sam Gnerre of The Daily Breeze wrote that "As early as the 1920s, the city had expressed unhappiness over being allied with LAUSD."
Lancaster created a campaign to establish a school district in the mid-1920s, but the first two formal referendums on secession, on April 11, 1932 and March 16, 1937, respectively, failed on 1,346-572 and 932-378 bases.
However on August 20, 1946, Torrance voters did approve a new city charter, 1,371-761, which allowed for a new district to be created.
