The purchase of an 18.9-acre conservation restriction last week will expand the Martha’s Vineyard Land Bank’s holdings at Sepiessa Point Reservation on the Tisbury Great Pond.

The land bank commission announced that it paid $654,500 for the restriction. The seller is Elizabeth Brown Bayer.

The property includes 2,180 feet of frontage on Tiah’s Cove, and is surrounded by the land bank’s 164-acre Sepiessa Point Reservation. Development on the property will be limited to a single building envelope around an existing home.

The land bank always invites members of the public with questions or comments about any of its properties to attend one of the commission’s regular Monday evening meetings. The office telephone number is 508-627-7141.
