A Special Town Meeting will convene in Town Hall at 7:30 p.m. Monday to consider a number of measures, including installing a solar array field on top of a local landfill. Town Meeting members will be asked to amend zoning bylaws, allow the town to extend a developer contract for 15 or 20 years, and approve $15,000 in town funds to build the field. Members will also consider a proposal to conduct a $650,000 feasibility study on whether the Hillside Elementary School should be renovated or rebuilt, and if rebuilt, where. Approximately half the study’s cost might be covered by the Massachusetts School Building Authority, officials said. The study is needed because officials are unsure whether it’s more cost-effective to rebuild or renovate the school at its current Glen Gary Road site, or build a new permanent school or temporary classrooms on a different site, selectmen said. Some residents support studying Cricket Field as a potential location, while others want the field left alone. However, town parks officials who manage the field have indicated they will not transfer the space to be used for a building, effectively taking Cricket Field off the table. Members will also be asked to vote on proposals to allow small restaurants to obtain full liquor licenses; create a $50 fine for medical marijuana users who smoke the drug, legally obtained or not, in public; use town funds to convert an abandoned rail trail into a passive recreation space; authorize modular classrooms to be built at Mitchell Elementary School at a cost of $2.7 million; and spend $1.4 million to buy the 66-70 Chestnut St.property next to the police station.
