The Public Works Department is nearly $235,000 in the red for the snow and ice budget this winter, Superintendent Michael Trotta told selectmen Tuesday. He added that the department has enough salt for an upcoming storm but that salt supplies were dwindling. Trotta came before selectmen to request a $50,000 increase to the snow and ice budget of $364,735 for next year, part of a set of rolling increases over the next several years so that similar deficits do not take place in the future. “I can’t argue with that this year,” Selectman Avril Elkort said, citing the multiple storms this season. The change will be considered along with other department requests.
