A tree house that Alna officials said was too near the Sheepscot River will come down by Feb. 8, according to a new letter from the owner of the property where it went up.

But the parts that comprised the unfinished tree house might remain on the lot until spring.

The planning board has set a special meeting for 6:30 p.m. Monday, Jan. 19, Town Clerk Amy Warner announced in an email Friday. The board will review Lisa Packard’s letter and consider what fine, if any, to recommend that selectmen give her.

The tree house at 91 Dock Road goes against the town’s shoreland zoning, according to planning board members and Code Enforcement Officer Stan Waltz. Waltz wrote Lisa Packard a stop work order on Jan. 7. Packard’s letter in response gives the Feb. 8 date for the tree house’s removal, and for her to submit a site plan Waltz requested. The plan will show where new trees will be planted, to replace dead ones that were removed.

The materials and cables used for the tree house will be off the property by May 8, the letter states.

“An earlier removal of cables in winter conditions could be dangerous,” Packard writes in her letter to the planning board dated Jan. 9. Town Clerk Amy Warner received it the week of Jan. 12.

The letters follow a discussion that the board, Waltz and Packard had earlier this month about the tree house, the removed trees and another issue that involved a cabin on the same property. Packard told officials she didn’t know about the court order that bars the cabin from being lived in. The order pre-dates Packard’s 2014 purchase of the property; she said a Somerville man had asked to stay there part-time to be nearer his children.

The man had begun building the tree house for his daughters for Christmas, Packard said. He was no longer staying at the cabin, she said.

Waltz’ letter to Packard requests a formal acknowledgment that the cabin can only be used for sitting or reading. In response, Packard writes that it will only be used for sitting, reading, writing and resting.

Packard did not immediately return a message seeking comment on her letter.

Baston told Packard on Jan. 5 that the town may fine her in connection with the issues discussed that night.
