The Tisbury select board has set Dec. 17 for a special town meeting, where voters will be asked to approve more than $8 million for library improvements.

Meeting Tuesday online, the board unanimously approved three building-related articles for the town meeting warrant, which will close in early November.

Two articles ask voters to borrow $8.8 million for improvements at the Vineyard Haven Public Library and override state borrowing limits under Proposition 2 1/2 in order to do so.

The $8.8 million request is based on estimates, project manager Michael Owen of CHA told the select board Tuesday.

Hard bids from contractors reflecting the actual cost of the library work will be available by the special town meeting, Mr. Owen said.

If both articles pass, a special election will be held Jan. 7 where voters will be asked to approve the borrowing plan.

A third article on the special meeting warrant seeks $600,000 from the town’s capital fund for professional services to begin developing a consolidated town hall at 66 High Point Lane, where currently a pair of aging modular buildings house municipal services including the planning and health departments.

The board is scheduled to finalize the warrant at a public meeting Nov. 4. The special town meeting will be held at the Martha’s Vineyard Performing Arts Center in Oak Bluffs, as the new school gymnasium remains under construction.

Also Tuesday, the board officially appointed police officer candidates Christopher Manning and Daniel Durawa, introduced by Tisbury police chief Christopher Habekost as lifelong Islanders and fully certified officers with police experience in other Vineyard towns.

Mr. Durawa has been employed full-time with the West Tisbury police department and Mr. Manning has been working part-time in the Aquinnah police and full-time for the Dukes County sheriff’s department, Chief Habekost told the board.
