HOPKINTON - We’re getting a little closer picture of how much the state will pay for Hopkinton to build a new Elmwood School. At their meeting this week the Elementary School Building Committee got an update from the project director. Calling the Massachusetts School Building Authority’s reimbursement formula “complex” for what it will and won't reimburse, the Hopkinton Independent reports the project director said of the current estimated project cost at $174 million, the MSBA could pay around 26% of it.
