The Brookfield Board of Selectmen has sent the $78.1 million Huckleberry Hill Elementary School building plan to the Municipal Building Committee. That group will oversee the project, through the construction process. Brookfield will hold a referendum in March for residents to vote on the proposal. The school would house pre-k through 5th graders, leaving Center School vacant. First Selectman Steve Dunn and Selectman Sue Slater approved the motion, but Selectman Harry Shaker abstained because he said he wanted the task force that developed the proposal to be more involved.
