According to well-placed source it's new Federal guidelines to blame. An open records request by DunwoodyTalk showed no evidence of emails to FERC by Dunwoody's mayor, council, or city manager suggesting new guidelines for tree height on transmission lines for the United States. FERC and NERC are to blame. Power companies face fines of up to $1 million a day if a tree causes an outage of transmission lines.
According to sources, any tree or shrub that has the potential to grow 15 feet or higher, and is now rooted under the electric transmission lines, is being cut and chipped. If you live along the power line take a good look now because in a month things will look very different. Playsets, gardens, sheds, and small shrubs are okay. Not sure how this will affect the formerly-promoted greenway paths for under these transmission lines.
No word on any deer/coyote relocation programs.
