GREENVILLE, Maine — Community members and officials packing a public hearing Tuesday debated whether a proposal to redevelop a partially defunct ski area in Piscataquis County is viable enough to bring long-term prosperity to the region. The $113.5 million year-round ski resort in Big Moose Township would include a detachable chairlift to the top of the mountain, base lodge that would function as a conference center, 63-room hotel, taphouse and restaurant, a zip-line tour ride and more, developer Perry Williams said during his presentation. More than a year after Williams of Big Lake Development LLC filed his application for a development permit with the state, the public hearing allowed the community to weigh in on the project.
