Scarborough voters will make a second attempt to approve a 2014-15 school budget Tuesday after rejecting an earlier version on May 13.

The Town Council has trimmed $324,000 from the $42.5 million proposed budget that voters rejected, according to budget documents. The most recently proposed $42.3 million budget is about $1.5 million less than initially requested by Superintendent George Entwistle.

The first referendum failed by a vote of 1,169 to 1,013, with 14.2 percent of the town’s 15,318 voters turning out at the polls.

In a nonbinding advisory ballot question, 1,257 voters said proposed spending was too high, 370 said it was too low and 516 said it was acceptable.

If the second referendum fails, another budget meeting must be held within 10 days to approve an alternative budget proposal and schedule a third validation referendum.

The process must be repeated until voters approve a budget.

This story was updated at 3 p.m. on June 11 to correct the amount trimmed by the Town Council.
