Fixing a Persistent Wet Spot Near a Pool with Area Drains

A wet spot 10 feet from the pool that stays soggy a week after rain is a low spot. The 12-inch fence-line berm likely backs up water. Fix: install an NDS area drain (12- or 18-inch box) in the low spot, pipe to a lower outlet. Or regrade to eliminate the depression with uniform slope. French drain alternative: 12-inch deep, 6–8 inch wide gravel trench wrapped in fabric from low spot to outlet.
