Norton residents once again gathered at the Conservation Commission public hearing to learn more about the proposed teambuilding camp proposed for Pheeny’s Island.

In a continuation of the Feb. 13 meeting, Chris Yarworth of Yarworth Engineering gave more detailed information on property lines and impact on area wildlife.

The island is 7.36 acres of surface area. The original conveyance in 1894 listed it as 6 acres.

“The 6 acres plus or minus as it’s referred to in the deeds was an estimate because the original deeds dating back to the 1800s, there had never been a detailed survey of the island prior to the work that we had done,” said attorney Matt Watsky.

Eighty-three trees out of the estimated 1,750 on the island will be cut down. Yarworth said the larger trees will be left intact, except for four which will lose their canopy to make way for a zipline 30 feet in the air. While there are wetlands in this section of the island, professional wetland scientist Scott Goddard said it will not be affected. He will also demonstrate that there is no adverse impact on the environment from the lobbed trees.

Platforms would be secured to trees by pressure bolts, which would not actually go through the trunk.

“If the course should disband, they can be taken apart and the trees will not be harmed,” Yarworth said.

Goddard also noted that no important species, as outlined by habitat evaluation standards, were located on the island.

Out of 30 or so concerns the Commission had about the project, about a third of them were addressed before the meeting was cut short at about 10 p.m. A continuation of the public hearing will take place April 23, while the remainder of the concerns will be listed on the Commission’s page on the town website.
