My home is in a new sub and the association has planted a maple tree in the peninsula between the side walk and street. The concern I have is that my septic field is about fifteen feet away from where the tree is. How deep do the roots grow? Should I take this tree out and plant a different type of tree that won't reach my field? :-/

I don't think maples are too bad. I would leave it unless it is a Silver Maple. The silver maples are cheap and fast growing. However their shallow roots cause problems with lawns and sidewalks. They are also prone to wind damage. Recognize them by their deeply cut leaves, silver underside, and silver bark.
