The Santa Rosa City Schools Board will address one huge topic Wednesday, unifying all of it’s 9 districts into one mega district. They will hear a presentation from an auditing firm hired to study such a move. Consolidating into one district could save millions of dollars, with little potential downside. But such a move is still risky and would require some time to fully implement. The meeting will start at 5:30 Wednesday night at the Santa Rosa High School multipurpose room.
