Michael Dutton has negotiated a three-year contract with Bridgewater and is set to start work as town manager on Monday. His annual salary was set at $127,500, with 2.5 percent raises in the contract’s second and third years. The position had been advertised as paying in the low- to mid-$100,000 range. Dutton’s predecessor, Troy Clarkson, was paid $92,500 a year. Richard Kerbel, who has been interim town manager since Clarkson’s departure in April, will wrap up a few days after Dutton begins work.
