Council members said they will begin wrestling with how the map could be used as a crystal ball into the future.
Town highway supervisor Dave Forbes suggested the committee use a map of build-out over the last 20 years as a measure of how quickly growth could occur over the next 20.
Town council member Hollis Blodgett said the map was an eye-opener for the board.
"I'm very concerned about this and where the town will end up in the future," said Blodgett. "This is certainly a preliminary to studying the comprehensive plan. It's been six or seven years and we need to take a very serious look. I encourage this board to start reviewing the plan in the very near future, and the committee's work has given us a lot of guidance."
