Middleboro voters will be asked to support a $12.1 million temporary override at a special election on Saturday.
If passed, taxes will be raised for the next 30-years, with the average tax bill increasing by about $120 the first year, and steadily decrease to $99 by year 10, and $60 in the last year.
The money will be used to build an addition and restore the historic police station that was built in 1825 as a general store.
Police Chief Bruce Gates says the renovations are necessary because the building is falling apart. He said the only municipal use for the building is as a police station, and other than the façade there is little left of historic value.
Former town moderator James Thomas opposes the project saying it costs too much and police are being held hostage to historic preservation. Thomas says the town should build a new stand-alone station and take up historic renovations as a separate project.
The polls will be open 7 a.m. to 8 p.m.
