Manteca Unified in the next five years could use Measure G bond money to build a replacement campus for Calla High — an alternative secondary school — on 40 acres along Tinnin Road south of Woodward Avenue that the district owns for the next comprehensive high school. It presents an opportunity for the City of Manteca to possibly secure a municipal library branch south of the 120 Bypass. But before that can happen two key elected bodies that talk a good game of seeking joint ventures to stretch tax dollars and maximize their benefits — the Manteca City Council and Manteca Unified School Board — would have to step up to the plate.
