I'm definitely interested in your progress. I'm brainstorming a similar idea in Alabama. I have sandy topsoil with clay underneath. I have acquired galvanized greenhouse arches that I'm going to use to build it. It's an older model and they don't make all the pieces anymore so hardware will be an issue. I have a spot on a hillside picked out. I was thinking the same issues of runoff and protecting from the ground. I was thinking it might be better for me to dig down, create terraces around it, with maybe a French drain around it. I will be on a hillside so I really just need to divert the runoff water. My main goal was to preserve the sides from wind damage with the berms. Optimally I'll utilize a ram jet aquaponics set up from a steam located at the bottom of the hill. I want to do solar to run fans and lights. I'll be reading other ideas on here but any advice is appreciated.
