Voters approved an estimated $4 million municipal budget Saturday at the annual town meeting, representing a slight increase over last year.

In the secret ballot, residents approved several spending measures including $491,000 for roads, $378,000 for the recycling center and transfer station, and roughly $520,000 for law enforcement and marine patrol.

Residents also authorized the three selectmen to continue researching a boundary dispute with Brunswick. Outgoing board chair Amy Haible said historical research shows that more than 200 acres of shoreland and clam flats may have been improperly ceded to Brunswick in 1998. The town is exploring options for reclaiming that land on the northern boundary of Harpswell Neck.

About 500 residents attended the meeting between noon and 8:15 p.m.

"It was a great day," Haible said afterward. "I just love town meeting. It's a marathon, but it is tremendous to see the people in action."

Haible said the town did not exceed the property tax levy limit set by state law.

Voters elected Ellie Multer over Dave Chipman to replace Haible, the one outgoing selectman. They voted to keep Bob Venard as road commissioner and Joanne Rogers as an MSAD 75 director.

The residents turned down a $50,000 proposal to contribute to Hamilton Place, a workforce housing subdivision being developed by the Greater Brunswick Housing Corporation. They also voted down a proposal to spend up to $50,000 to help build a power-generating wind turbine for town hall.
