So I bought a 15'x42" Intex pool, put it together, and came to the realization that our yard is more sloped than previously thought! Hired a landscaper who recommended not digging down because natural water drainage would be interrupted. We're in Portland, OR, where summers have gotten hotter, but we still get occasional rain and the water table is a bit higher where we live. He used fill dirt and packed it down. Now we're afraid of the dirt flattening and causing problems. Also, the area is further from the tree than it appears in the picture. I'd appreciate any suggestions!
