Thus, there are no local officials’ salaries to pay and no infrastructure to maintain locally. And the cost of servicing each township is spread across the Unorganized Territory either in each county or statewide.

“It’s basically like a company: There’s so much less overhead,” said Paul G. Bernier, the public works director for Aroostook County, who is responsible for overseeing services to the unorganized territories at the very top of Maine. “Sometimes it’s half of what they were paying.”

In Aroostook County, Bancroft, population 60, completed the process last summer and now exists in name only. Besides Cary Plantation, Oxbow, about an hour northwest, is well on its way, although both have legislative approval and a final vote yet to go. State officials said that an effort to deorganize Atkinson, which began in 2013, may soon take a step forward, and that more municipalities had told the state that they were interested.

“Just the price tag to keep their local governments up and running is more or less untenable,” said Mark Brewer, a professor of political science at the University of Maine. “It’s the final step in this long, drawn-out process, which really starts with population decline.”

Marcia McInnis, the fiscal administrator for the Unorganized Territory, estimated there have been 41 deorganizations in Maine’s history, about half of them during the Great Depression. But “it has become recently more common than it has been in the last, really, two decades,” she said.
