The Aquinnah town library will receive a $50,000 grant from the Massachusetts Preservation Projects Fund for emergency building repairs, the town learned this week.

Total repairs could cost $100,000. In March, selectmen pledged to raise money immediately for repairs to the library foundation and its floor, that has reportedly sunk 10 inches in recent years.

The annual town meeting includes a warrant article asking the town to approve $100,000 in borrowing which would be repaid using Community Preservation Act funds.

As a result of the grant, annual town meeting could amend the article to lower the amount requested. “But we’ll see how that shakes out at town meeting,” town coordinator Jeffrey Burgoyne said.

Town accountant Marjorie Spitz wrote the grant which was approved May 1 by William F. Galvin, chairman of the Massachusetts Historical Commission. The library is listed in the national register of historic places.
