Manteca Unified schools will be split up for the 2018-2022 alignment cycle, if the Sac-Joaquin Section has its way. The section held its first of a possible five realignment meetings Wednesday at The Reserve at Spanos Park in Stockton, revealing a proposal that would have Lathrop and Weston Ranch leave East Union, Manteca, Sierra and the rest of the Valley Oak League behind for the Western Athletic Conference. Manteca Unified administrators have previously balked at a suggestion for its smallest high schools to move out of the competitive VOL and into one with schools closer to their enrollment size.
