On Monday night, Chilmark voters will be asked to join the other five Island towns in allowing the Martha’s Vineyard Regional High School District Committee to sell the office building of the superintendent of schools in Vineyard Haven.

Chilmark is currently the only town that has not yet agreed to join the petition for special legislation necessary to allow the sale.

The special town meeting begins at 7:30 p.m. in the Chilmark Community Center; moderator Everett H. Poole will preside. There are nine articles on the warrant.

If the school article is approved, it will allow the school committee to move forward in their plan to move the superintendent’s office to the former Edgartown School building.

Chilmark selectmen refused to put the article on previous town meeting warrants without more information about the total cost of the move, and the plan for the use of the old school building in Edgartown.

Selectman Warren M. Doty said this week that superintendent Dr. James H. Weiss has since promised that the only money that will be used in the move will be money made on the sale of the current office building in Vineyard Haven. The plan calls for the superintendent to occupy half of the old school building, with the other half used for community arts programs.

On Monday night voters will also be asked to spend $2 million to build three rental duplex buildings with six apartments in the Middle Line Road affordable housing complex. Middle Line Road is the first town-owned affordable housing project in Chilmark. The project has been in the works for more than four years.

Rental units represent half of the project; another six lots will be used as resident homesites, with a lottery for potential homeowners scheduled for January.

If voters agree, the town will use $600,000 in Community Preservation Act funds, and borrow another $1.4 million. Mr. Doty said project specifications have already been prepared, and the projects could go to bid soon after the special town meeting, if the article is approved.

In a related article, voters will be asked to appoint the Dukes County Regional Housing Authority to manage the rental units.

The warrant also includes several housekeeping spending requests.
