The town is grappling with the loss of $800,000 in promised state money midway through the fiscal year. Governor Deval Patrick cut $750,000 in prison mitigation funding and another $50,000 for hosting a state prison as part of $540 million trimmed from local aid payments statewide to make up for lower than anticipated state revenues. “I’m frustrated and disappointed,” said Town Administrator Michael Boynton. He said the town had planned to use the mitigation money for capital projects, such as school roof repairs and a new pumper truck for the Fire Department, and will have to either find a new funding source or drop the projects for this fiscal year. “When you have a capital plan in the $2.5 million range and take $750,000 out of it, that’s a lot of money,” he said.
