Voters will be asked to approve a town operating budget that’s up 2.7 percent compared to last year and act on 49 agenda items.

On Tuesday night, Selectmen closed the agenda for the Annual Town Meeting scheduled for May 11 at 6:45 p.m. in Sippican School. With the agenda closed items can’t be added or removed.

Some specific items include a $237,000 request for a new ambulance, a $500,000 appropriation from community preservation funds to renovate the Town House and $455,000 to study upgrades for the wastewater treatment plant.

Finance Committee Chair Alan Minard had asked the board to delay closing the agenda. Minard received the final draft at 4 p.m. on Tuesday. He said his committee needed time to review the articles before making a recommendation.

“There are three or four articles that may or may not have a cost impact,” Minard said. “We’ve got no information one way or the other.”

Town Administrator Paul Dawson said closing the agenda doesn’t prevent the Finance Committee’s recommendations from being placed on the agenda.

“There will be time for the Finance Committee to meet even if you close the warrant tonight,” Dawson told Selectmen.

Minard also provided Selectmen with an overview of the budget.

The committee recommended spending $20,455,858 for the next fiscal year. The budget is up $543,327 compare to last year.

Contractual obligations and education are the main factors driving the increase, Minard said.

“The increases in the budget that are most difficult to deal with are the ones we don’t have control over,” he said.

Total school spending, roughly half of the town’s budget, would increase 2.3 percent. That includes Sippican School, the town’s share for the middle and high schools and an assessment for Upper Cape Regional High School.
