Congratulations to the community and students of Watertown on the opening of their brand new high school! You can tour the building in-person today beginning at 3:00pm or take a look at the video below to see what a modern high school facility looks like.
The new Watertown High School was built for 720 students and cost $210.8 million, or $1,054 per square foot (not including the 136 car parking garage).
The school was accepted into the MSBA process in December of 2017, after being rejected in 2014, 2015 and 2016. Construction began in the fall of 2023.
Per Watertown News, "Watertown qualified for a 45.52 percent reimbursement rate, and added 2 percent in incentives for energy efficiency and 1.81 percent for the maintenance program, for a total reimbursement of 49.33 percent. The reimbursement only covers 'eligible' items. The MSBA only covers certain sizes for facilities such as the gym and auditorium, but Watertown chose to go with larger ones. The MSBA also does not reimburse for swing space. The cost of the additional space was covered entirely by the City." Ultimately, Watertown's MSBA grant of $51.2 million covered 24.2% of the total cost.
By comparison, the most recent;y proposed Andover High project aimed to begin construction in June 2025, had a target design enrollment of 1,900 students, and through feasibility design was anticipated to have cost $450 million.
