Most large capital projects in Bridgewater are paid for over a period of time, from five to 30 years. Once voters approve, the Town takes out a loan in the form of a bond to pay for the construction and associated expenses, and then pays back the bond through annual payments of principal and interest, much like a regular mortgage.
In each of these anticipated projects, voters have the final approval through a ballot vote which, if positive, allows the Town to pay for the project through a debt-exclusion. This means taxes are raised just enough to cover the annual bond re-payment cost. Once the bond is paid off, then that additional tax payment goes away.
