Selectmen have opened the warrant and are soliciting articles for the annual Town Meeting on May 7. Items may be submitted through March 15. Town Administrator Allan R. Chiocca said the warrant will include three articles related to building a new senior center as well as the annual budget items. The $4 million senior center project will use land off Albion Street to replace shared quarters in the Community Building. Chiocca also noted there will be two new officials making their debuts at Town Meeting, with Town Clerk Mary Pat Kaszanek and Treasurer Karen Sepeck both opting against seeking reelection this spring.
