The town is preparing to construct a new multipurpose synthetic turf field at the high school after a Special Town Meeting recently appropriated $600,000 from the town’s Community Preservation Fund for the purpose. The overall project is estimated to cost $950,000. The other funding sources are a $250,000 state grant, $50,000 in private donations, and a portion of the $100,000 the town is saving by not proceeding with its previously budgeted plan to build a grass field, according to town manager Richard Montuori. The new field could be used for football, lacrosse, soccer, field hockey, physical education classes, and other events. It replaces a grass field that was lost when the town built the new high school, which opened last September. In keeping with requirements of the Community Preservation Act, Montuori said the $600,000 from the preservation fund would not be used to purchase the synthetic turf, but for other features of the project.
