A $100 million budget is ready to go before Town Meeting voters next Tuesday, and town manager William R. Ross said in an interview that it is the earliest a budget has gained approved from town selectmen, the Finance Committee, and School Committee in recent years. The municipal portion of the proposed budget will be just under $36 million, up about 1 percent from last year. The school’s portion will be $44.2 million, with the remaining funds going toward revolving and enterprise funds for waste water, the airport, and the town’s municipal electric plant. No layoffs were necessary this year in either budget, Ross said. Some adjustments were made in staffing in the schools to match enrollments that are declining by 150 to 200 students a year, he said. A separate article for a debt exclusion to Proposition 2½ that would allow the town to borrow $13.6 million over 20 years to build a new public works garage will also be before voters. It will need approval from at least two-thirds of voters present, Ross said. Town Meeting will begin at 7 p.m. at Mansfield High School. The full warrant and budget are available at mansfieldma.com.
