The Coeur d'Alene School District board of trustees voted unanimously on Monday to approve the $78,878,379 budget for the 2012-13 fiscal year.

Slipping $5 million from the previous fiscal year, the new budget includes two unpaid furlough days for teachers, and cuts to faculty and curriculum.

The budget drop largely reflects fewer available funds, said Wendell Wardell, the district's chief operating officer.

"In the next two years (the budget) will be $3 million less than that," Wardell said on Tuesday of the district's fiscal plans.

The approved budget includes a $60.2 million general fund, down $2.6 million from last fiscal year.

The district budget slid partly due to the loss of roughly $2 million in one-time state tax revenue, Wardell said, which last year's Legislature shared with the school districts.

"They've been pretty careful to not involve it in things that call for recurring expenditure, because it wasn't going to recur," Wardell said of how the one-time funds were used. "I can tell you they were real careful to keep it from impacting classrooms, because it would have had a negative impact as soon as it disappeared."

Lower enrollment also drove down the budget, Wardell added, though he said the district has only lost about 110 of its more than 10,000 students.

To address shortfalls, the school district had negotiated the reduction of $3.2 million from the budget during the recent teacher contract discussions.

That included general fund cuts like foregoing the purchase of two buses, lowering the curriculum budget by $300,000 and cutting nine teacher positions.

"We've tried to be very careful to try not to impact the quality of education," Wardell said.

The district fund balance is also decreasing by $1.3 million, and the district's contribution to family health insurance is lowering by 2 percent.

Teachers will take two non-instructional furlough days.

Wardell said the district is expecting additional funds for performance pay under the Students Come First legislation.

The amount might not be known until after September, he said.

"It's going to be helping education any time that we have a focused expenditure," Wardell said.

The district's contingency fund for the new budget is $2.7 million.

Due to shortfalls, the district has cut its budget $8.8 million between 2009 and 2011, according to the 2012-13 budget document on the district website.

The school district is asking voters to approve a $32.7 million bond this August to fund infrastructure improvements at several schools.
