BATH — A new cost-sharing formula that would assess the five communities of Regional School Unit 1 on a per-pupil basis goes to a referendum vote Tuesday, March 19.

Polls will be open at Bath Middle School, the West Bath fire hall and Woolwich Central School from 8 a.m. to 8 p.m., and at Phippsburg Town Hall from 1:15-8 p.m. They will also be open at Arrowsic Town Hall.

The RSU 1 Board of Directors unanimously adopted the new plan last December for implementation in the 2014 fiscal year budget cycle.
