The leader that failed was closest to the porch of the building (plus or minus 40 feet) , the prevailing winds blow toward the historic building and the (now) missing leader was all that stood between the tree blowing over in the next storm and the building. It scares me just thinking about it. The owner has been informed that it is now, officially, a hazard tree and needs to be removed ASAP. Also, that his insurance may not pay up if the tree fails between the time it was declared a hazard and the time it's to be removed if he delays the removal. Last I heard, he wants to try and get the power company to take it down since it's close to their ROW. Oh well, I've done what I could.
