Looking to build a 10'x12' storage shed in the backyard. I've settled on using the TuffBlock system. I have the area marked out already and there's some grass in the area. Should I dig it all up or not worry about it? I'm planning on the shed sitting 4-6 inches above ground with something to cover up the gap afterwards.

My initial thoughts were to just dig up the areas for the blocks and put in some drainage rock, while leaving the grass. How far off am I? (first shed, all diy)
