Greetings Steve:
Occasionally, due to the litigious nature of society here in the United States, I have to refrain from answering certain forestry-related questions. When these uncommon situations occur, I must simply inform our readers to contact a local certified arborist, forester, or horticulturist in order to provide on-site guidance and answers.
Unfortunately, your tree safety question falls into this category. Therefore, please contact a local certified arborist, forester, or horticulturist to provide on-site guidance.
Best of luck!
