Using Northern Pass's own projected tower locations and tower heights, the Appalachian Mountain Club created a series of flyover videos showing the visual impact of the proposed overhead towers. For their part Northern Pass objected to the AMC's visual representation. Of course Northern Pass has also been telling those who live near the proposed transmission line that they will "pay to put up awnings" or "plant 100-foot trees" to block views of the towers, somehow missing the point that abutters want their view unspoiled, not blocked. As an aside, successfully re-planting a 100-foot mature Eastern White Pine successfully is a somewhat ludicrous idea.
It's also worth noting that former PSNH CEO Gary Long, in touting Northern Pass, has said that in his case he "likes to look at towers." So maybe the disagreement isn't so much about how many towers can be seen from where but whether or not they are appropriate structures in places like the White Mountain National Forest and other conserved lands.
"Northern Pass’s June 2013 preferred route for the northernmost 74 miles is of great concern to our organization and many others who value northern New Hampshire’s character and rugged beauty," the AMC said. "The AMC is conducting a new visual impact analysis of the half-mile range along the full Northern Pass corridor and we provide the video series depicting the visual impact of proposed transmission towers along the 186-mile route."
