How do you fix a sloped, rocky, clay backyard?

Well bermuda gr will grow anywhere, personally I hate it, but I'm certainly in the minority. With the slope, and depending on the grade, you do could some very creatively things will walls and terraces; which will also help move excess water away from your house.The terraces could hold a nice variety of trees, gres and shrubs and the base of the slope could make a nice green area, not too big, remember, gr is not our friend. The previous suggestion of a water fall with a pond also could have some great potential, the labs would love it. Good luck
