We have a decently big back yard. We are currently in the process of building/pouring a covered stamped concrete patio. With that, we've gotta bring some dirt in to make sure the patio looks even all the way around (yard is very uneven). So we are wondering, should we tier the yard into two sections, or should we just bring dirt in and leave the slope? I've attached pictures for reference. Also if we tiered it, would it make the fence look super short in the high areas? Hope this makes sense! In the picture with the black line, that's where I imagine the yard would split for the tier.
