Hey all,
Looking for some help in my thought process with this tree and deciding mitigation.
65ft Bur Oak, codom split at about 7 ft, centralized column of decay 35%,

healthy growth on side closest to lane, declining on opposite side. 50% root coverage from when lane was built 20 yrs prior. Crack active on one side, sealed and no movement in high winds on other.

Im stuck on guiding the better of mitigation options.
I don’t want to brace rod the trunk and destroy the CODIT wall4 that is saving the tree. I like the idea of the Cobra Cable, but is it worth it? Better to subordinate the failing codom and be done with it? Hopefully the pics work to get a better idea.

Thanks all!

Why does it need to be saved?
Why have a failing and declining tree that close to the laneway?
Doesn't really look liked it would be missed with all the trees behind it IMO.
If it really needs to stay, just install a steel cable for a bit of insurance while you see if the tree is going to live or die.

Absolutely, there are lots of trees behind it, this is one of the larger ones on the property and is rather striking as you enter the lane way - hence why they are trying to keep it if possible.

I would be inclined to put a rod just above the junction and a steel cable. I would be willing to sacrifice Wall 4.
I'm not sure subordinating the back codom is going to mitigate the risk of the front stem failing.
This is what makes portions of arboriculture a black art rather than a science.
