The Martha’s Vineyard Land Bank added 400 feet of white sand beachfront to its holdings in Vineyard Haven Friday with the purchase of a five-acre parcel near the mouth of Lake Tashmoo on Vineyard Sound.

The sale price is $1.9 million for 4.7 acres. The seller is Virginia Ursin.

The new property lies off Herring Creek Road and abuts the town/county beach. The purchase will effectively triple the public beachfront there, the land bank said in a post on its Facebook page. It also lies adjacent to Wilfred Pond Preserve, a small land bank beachfront property east of the Tashmoo opening.

Two summer cottages on the new beachfront will be taken down, and a dune will be restored to its natural state, the land bank said.

Preliminary management plans call for the property to be open for fishing, swimming, boating and other riparian uses, and nesting terns will be protected, the land bank said.

Plans call for the property to be open for public use by next summer.
