The Chilmark select board Tuesday approved a $9 million dollar bond to help pay for the new public safety complex now under construction.

The $12.3 million complex will include a new fire station and a separate building to house the Tri-Town ambulance. Dellbrook of East Falmouth is the contractor.

David Eisenthal, the town’s financial advisor, met with board members Tuesday to review the detils of the bond, which will be paid out over 20 years with annual payments hovering around $465,000 plus interest. Payments will be made to Piper Sandler Companies, an investment bank which the town awarded a bid for the bond to last week, Mr. Eisenthal said.

Selectman Bill Rossi, who is on a committee overseeing the project, also gave a progress report. Foundations are nearly finished and the project is on schedule to be completed by next spring, Mr. Rossi said.

“I think we’re in good shape,” he said.

Selectman Warren Doty shared a bit of wisdom he recently received from Billy Dillon, an Island carpenter who is serving as clerk of the works for the project.

“He said the hardest part of a project is getting it out of the ground, so that’s right where we’re at,” Mr. Doty said.

In other business Tuesday, the board signed a letter of support for a new five-year plan for the Martha’s Vineyard Center for Living and Healthy Aging Martha’s Vineyard.

Representatives from the two nonprofits, which share a mission to provide support to the Island’s elderly population, said the plan and accompanying letter are part of an application for the Island to become recertified as an aging-friendly community. The groups are also applying to become a dementia-friendly community for the first time.

“The Island, I think, has been really unique in its care for its older adults and its willingness to make it a priority,” Healthy Aging executive director Cindy Trish said.

The board also agreed to add Juneteenth as a recognized holiday in the town.
