Bamboo would work, but it's gonna get tall. Realistically, you could build a berm over the poor soil and then use just about any plant you want.

Ive planted bamboo on the north and east sides of my property and I love it. I built berms to plant them on so they wouldn't drown in the rainy season. I don't want to build up the front of my property because the water wouldn't be able to drain..

seagal007, my heart really went out to you about what your property was filled with. I'd be tempted to try arundo donax because when established it sucks up excess water like straws, but I know it is on the top evil weed lists for our entire country.

So another thought I had was for native climbing vines. Maybe your frontage is too wide for the cost of this project, but could you install some four x four posts and span some kind of wire fencing, even cattle panel, across, and then plant some native climbing vines all along the bottom?

I say native especially because I have had such bad experiences myself with exotic vines, namely English ivy and Asiatic jasmine, not to mention all the others that swallow up a grove of trees in a matter of months.
