At this time, it seems more likely that I will have to use a trencher and
will thus only have a 30-inch cut. I'm not too sure if I can keep the water
away from my house with this shallow cut.

You should be able to rent a larger trencher. The one I used made an 8" cut to
48" depth. They are only about 4 feet wide, and place the dirt neatly along one
side as they go.
