Here is the pile of branches that fell into my drive way. I had to get out the car to remove them. I couldn't drive over them. I think this tree is diseased. It has these light green spots on it. It has been dropping little pieces in the driveway and on my car for about a year. But now it seems whole branches are dropping off. I park all the way up the driveway to avoid branches fall onto my car. Maybe a trim or treatment would help.
