He has said the community wouldn't be based on religion and would be open to anyone.
Many residents in the rural, mountainous region with a total population of about 6,600 fear such a large-scale development would change the character of their small communities, tax resources and limit access to recreational areas and mountain views.
"The NewVistas development threatens what many Vermonters hold most dear, which is strong communities and local control over governance," Michael Sacca, president of the nonprofit Alliance for Vermont Communities, told fellow Tunbridge residents before the vote.
The nonbinding resolution against it, he said, "will tell our local, state officials and our neighbors and especially David Hall how we, the voters of our town, feel about this development."
Resident Bob Dunkle, who is also a member of The Church of Jesus Christ of Latter-day Saints, warned that he's seen sprawling developments out West and doesn't want that to happen in his town.
"It's more like a family community than anything else, but you will lose that identity if you don't do something quickly and take this guy seriously," he told the crowd. "He doesn't intend to stop. And he hasn't asked for anyone's permission, and he really doesn't care what your opinion is."
Hall didn't immediately return a phone call or email seeking comment. He has said he expected locals to be opposed but hope they will grow more accustomed to the idea as they see other such developments built.
Hall hopes to build a similar eco-friendly community in Provo's Pleasant View neighborhood, but has run into opposition from many residents and city leaders.
So far, his foundation has bought about 1,500 acres in central Vermont and plans to buy more.
"No actions by any group will dissuade us from continuing to purchasing land as it becomes available and as we have budget," he said in January.
