FOXBORO - The Boyden Library has been awarded a provisional $3.4 million grant toward the expected $10.3 million cost to expand the library.

Plans call for the library to grow by about one-third, to 35,000 square feet.

Grants for 31 library building or renovation projects statewide, announced by the Massachusetts Board of Library Commissioners, are conditioned on the communities funding their share of the project by Dec. 31, 2009.

"It's good they got the money appropriated," Library Director Jerry Cirillo said. "It's good to give the town the opportunity to expand the library by about 33 percent. If we don't do it now, it could be another five years before they have another grant round."

Library trustees will take up the issue at their meeting Monday. Foxboro taxpayers are already facing two potential requests for overrides.

School officials have made it a priority this year to seek a state grant and local funding for a what could be a $13 million renovation of Foxboro High School.

And, the board of water and sewer commissioners have floated the idea of a $3 million override request this fall as part of its effort to regionalize the town's sewer system.

The Boyden Library opened in 1968 and is about 20,833 square feet on three levels.

In addition to needing space for its collection, the library needs heating and ventilation, plumbing, electrical and other work.

The elevator is too small to meet the needs of people who uses certain kinds of wheelchairs and the windows are single panes of glass and are energy inefficient.
