Taken from Portland tree code
Roots over 4 inches in diameter should not be cut.
root encroachment zone is one foot for every inch of diameter.
See this handy pamphlet.
What is the diameter of the oak tree? Circumference is ~83“. Therefore, Radius is 13.2”, Diameter is 26.4“.
We cannot be closer than 13.2' from the tree. Aha! It's measured from the CENTER of the trunk, which saves us a bit. yay!
