The developers who recently lost their bid to build a private golf club on some 200 acres of land along the Edgartown Great Pond intend to file a new plan and try again.

“We are neither dead nor finished,” declared a letter sent to the founding members of the Meeting House Golf Club one day after the plan was voted down by the Martha’s Vineyard Commission.

The letter was sent by mail and by fax to 30 seasonal residents of the Vineyard who advanced some $2 million in start-up money for the failed golf course project.

The developers who want to build a golf course along the Edgartown Great Pond jacked up the pressure this week in an attempt to gain favorable votes from members of the Martha’s Vineyard Commission.

Opponents of the golf course project also are waging a lobbying campaign, including a series of paid advertisements, but the campaign by the developers is now clearly accompanied by high-pressure tactics more commonly seen in Boston than on the Cape and Islands.
