IRVINE - A reduction of fourth- and fifth-grade science class time  was the sole item spared  from the proposed adjustments and cuts list  that Irvine Unified school board members voted on tonight in an effort  to save $12.6 million. The district is preparing for a expected budget  shortfall.

The board approved all other staff recommendations,  which included increasing athletic transportation fee from $125 to $245  starting next school year and increasing grades 4-12 class size by  cutting teachers. The latter would save the district about $2.5 million.

One  of the recommended cuts by district staff was to reduce fourth- and  fifth-grade class time taught by a science specialist from 120 minutes  per week to 90 minutes a week. Board members Sharon Wallin and Gavin  Huntley-Fenner recommended that the district use money from the Irvine  Ranch Water District to pay to keep the additional science instruction.  The district has more than $3 million left from money that the water  district has paid to use the school district's land on Barranca Parkway  and Harvard Avenue for water treatment, Huntley-Fenner said. The board  unanimously approved that proposal.

Other approved adjustments  included reductions of district office positions, special education  costs, and work hours for assistant principals and health clerks.

More  than 20 district students, parents and staff will fly to Sacramento on  Wednesday morning to talk with state legislators about their budget  concerns. The district is required to adopt a budget by June 30,  although the state budget is often not finalized until August or  September.
