Members of the College of the Canyons Board of Trustees voted Wednesday to endorse Proposition 30’s proposed tax increases on the November ballot.

The motion passed by a 4-1 margin. Board member Scott Wilk, who is the Republican candidate in the 38th Assembly District, was the lone dissenting vote.

If passed, Proposition 30 would generate an estimated $6 billion in annual revenue until 2017. If Proposition 30 fails, it would reduce the 2012-2013 budget by that same amount.

If that occurs, COC would take a $4.6 million budget cut in the 2012-2013 academic year, according to the trustees.
