Cuesta College trustees Wednesday adopted a tentative budget for the coming fiscal year, acknowledging that future cuts must be made to ensure the college’s fiscal survival. The college is grappling with a $650,000 deficit, which is projected to grow to $1.1 million in the 2010-11 school year. That gap is anticipated to reach $6.9 million two years later in the 2012-13 school year if spending is not curbed or revenue increased.
