Football association with Pacific View League
In April 2019, during the biennial releaguing process in the Northern Area of the CIF Southern Section, administrators from member schools approved a proposal to create an association with the Pacific View League in the sport of football only. The association, composed of the 12 schools from the two leagues combined, assigns each school to one of the leagues, with promotion and relegation taking place every two years. The plan was originally scheduled to begin in the 2020–21 school year. However, the COVID-19 pandemic has delayed its implementation, as the 2020 football season was postponed and shortened; upon the return of sports in early 2021, health officials in Ventura County prohibited schools there from playing teams in adjacent counties (this restriction was later lifted). In May 2021, another round of realignment saw the merging of the Channel League with the Pacific View League, beginning with the 2022–23 academic year. For the 2024–25 academic year, the Northern Area reorganized its constituent leagues again, adding a new football league called the Conejo Coast League.
