I have used a "Thoroseal" product inside a CMU full height basement with regular flooding problems; in the last 3 years it seems to have helped a lot.
You can garden on slopes. It is doing earthworks on slopes that makes a bad, I.e. Unstable condition.
I could hugelkultur there, or simply plant. (It's already planted for erosion control.) I think the slope is probably about 40 degrees or so. I just don't know if I'm going to clear more trees or not. Time will tell. I have plenty of projects from just this thread to kill my vacation for this year!
Any slope 20 degrees or greater is supposed to be left alone (not brought into production). Still, it might be a good idea to remove the trees closest to the house so they don't fall on the house. You could use those trees to make a terrace Sepp Holzter style. The plant shade tolerant species in the terrace.
