ADAMS, Mass. — Four candidates will be vying for two vacant seats on the Board of Selectmen.

Nomination papers were due Monday and Richard Blanchard, Joseph Nowak, Donald Sommer and Michael Young have all returned papers to be on the ballot. They have until April 3 to withdraw their nominations.

That's one short of last year, in which five candidates tried for two seats. The race also ensures new faces on the board — albeit Sommer has served before.

The two three-year seats available are those that had been held by Paula Melville and Scott Nichols. Melville resigned from the board last year and Nichols has opted not to run for re-election.

Nichols instead will be running for moderator against Edward Driscoll, another former selectman. Both are looking to fill the seat left vacant by Joseph Dean Jr., who died in December.

The one-year seat left open by the resignation of former Chairman Richard Frost on the Board of Health will also see competition with two candidates. Glen DeMarsico and Allen Mendel are both vying for it.

A three-year Board of Health seat held by Roy Thompson is also up for election but Thompson will run unopposed.

Three people will by vying for one three-year assessor seat. Dennis Gajda, Lorraine Kalisz and Susan Rowe have all returned papers to run.

There are a number of unopposed elections as well; Holly Denault for treasurer; Karen Kettles for library trustee, Martha Stohlmann for Planning Board; Lawrence Clairmont for cemetery commissioner; Elizabeth Buskey for Redevelopment Authority; and Joseph Allard for McCann School Committee (Northern Berkshire Vocational School District). Paul Butler and Joshua Ryan DeMarsico-Birkland are running unopposed for two seats on the Adams-Cheshire Regional School District Committee.

A three-year library trustees, a five-year Housing Authority seat and a one-year Redevelopment Authority seat have no candidates.

The town election is Tuesday, May 6.
