also try a moisture trapping system.

look up what geoff lawton at the permaculture institute has been doing

http://permaculturenews.org/author/geoff%20lawton/

you can put in some swales that match the existing terrain, put a 4″ collecting line with little mini drain tubes to wick water up to the surface, fill the swales
with cellulose.

then plant various plants that use the cellulose as moisture feeds.
