The design of the new Watertown High School got the endorsement of the Massachusetts School Building Authority on Wednesday. Superintendent Dede Galdston sent out a letter saying that the MSBA Board of Directors unanimously supported moving the WHS project to the schematic design phase. “At this time, the design team, the OPM, and the School Building Committee will prepare for the next big milestone, the Board approval of participation in our project,” Galdston said in a letter to school and town officials.
