FOXBORO - Voters in May will be deciding a roughly $10 million school building question.

Selectmen this week voted to place on the May 4 town election ballot a debt exclusion override question for the repair and renovation of Foxboro High School.

The board previously voted to place the appropriation on the May 11 Annual Town Meeting warrant.

The capital improvement committee on Saturday unanimously supported the approximately $20 million FHS project. School officials hope to gain approval for 50 percent or more reimbursement through the Massachusetts School Building Authority.

The MSBA plans to meet March 25 and may decide the reimbursement question that day, according to school business administrator Paul Jackson. A debt exclusion override asks townspeople to voluntarily increase their taxation for a period of years - possibly 20 years. Selectman James Thrasher Tuesday quipped that as a person gets older, a 20-year tax hike begins to sound permanent.

School officials are planning a series of information sessions, including at the senior center, concerning the project.

A detailed presentation is scheduled to be made March 23 during the school board's regularly scheduled meeting. The architect, Kaestle Boos company, project manager, Construction Management Services, and a representatives from the town's Permanent Municipal Building Committee will be present.

The school committee on Monday voted to recommend that selectmen appoint board member Katie Adair to serve on the building committee, succeeding Larry Harrington.

The project will include a new roof, windows, heating and ventilation, fire alarms, boilers, gym floor, access improvements for disabled persons and a new gym floor and renovation of science labs.

All but the roof is original equipment in the nearly 40-year-old building. School Committee members and other town officials have said failure to make the repairs will only result in higher spending later.

"A lot of these systems have outlived their useful life," Jackson said.
