Bahia has very deep roots which makes it drought tolerant. It doesn't do great in clay but will grow there when other grasses won't. It is also very fast growing grass with its seed stalks jumping up a couple of inches a day when it really gets going(Might think about that if you want low growing). Like others have said it is a dominate grass and will crowd out other varieties. On the other hand if you want it to spread and fill in areas that might be a good thing as it produces prolific seeds on its seed heads. As Flame notes it is hard to cut. Sharp mower blades or multiple cuts will be necessary.

Toss up on what to plant. In this drought that could last all year you are going to have to water anything you plant to get it established.
