looks like a *acer rubrum* red maple, scarlet maple, swamp maple.. a tree that size with roots that deep should be fine thru a drought. They grow really fast. well if you take it down just think of all the sun light you'll let on the rest of your landscape. we just took my dads down the other week, it was over 35 feet tall, he lost sun in his pool at 4pm every day. so now he's happy, more sun in the pool..lol if you have a pic of a leave i cant tell you for possitive..
