Just bought this pool and had to dig up the yard a bit to get some flat space for it. The video said something about leaving six feet of space around it, I think. Can't do that, but since we're going to have to build some retaining walls I needed to know what the actual footprint of the pool is. Do the legs stick out more than a foot or would that be enough clearance all around? The wall would be along one of the shorts sides, on the left side it would be about half the length of the pool and on the right side, maybe a quarter of the length. So would 14 feet of space be enough, or do I need more than that?
