A new Public Works building, affordable housing developments, and medical marijuana dispensaries are among the topics slated to be put before Special Town Meeting voters this week. The Special Town Meeting kicks off Monday at 7:25 p.m. in the high school auditorium, and will be continued on Thursday if necessary. Selectmen chairman William Plasko said in an interview he hopes the proposed $16.8 million DPW building proposal gets the necessary two-thirds vote. He said the department needs the new facility, and a responsible financing plan has been put together to pay for it. Voters will also be asked to consider “smart growth” or 40R developments, including Plimpton Press, Regal Press/Guild Street, and a smaller one on Washington Street. Unlike “40B” developments, these proposals must receive voter approval and could result in the town receiving money from a state fund. They are generally located in downtowns, close to public transportation. An extension of the medical marijuana moratorium from June 30 to Sept. 30 is also on the warrant. Plasko said the committee needs more time to draft bylaws.
