SAN FRANCISCO (AP) — California community college leaders warned Wednesday of an unexpected budget shortfall that could lead to more cuts in courses, staff and services. The 112-campus system faces an additional $149 million deficit because of lower-than-expected property tax revenues and greater demand for student fee waivers, said California Community Colleges Chancellor Jack Scott. The shortfall comes on top of a $400 million reduction in state funding for the current fiscal year and a $102 million midyear cut triggered when state revenues fell below projections.
