I have 6 redwood trees in my backyard that PG&E want to trim down 40 feet, they are in the way of their wires, normal they cut them back 20 feet per year but in order to save money the want to do this every three years. They tell me if I object they have the right to remove them, I live in Martinez, CA. I have a beautiful landscaped yard which was the selling point of me buying the house. Please tell me what my rights are?
