Expert Response
Thank you for your question, John. I suspect that your tree is the victim of a soil-based fungus described here: https://pnwhandbooks.org/plantdisease/host-disease/maple-acer-spp-verticillium-wilt This is an incurable disease that impacts many maple trees.
However, before removing the tree, I suggest that you submit plant and soil samples to the OSU Plant Clinic for diagnosis: https://bpp.oregonstate.edu/how-submit-plant-materials
Good luck!
