Complex Drainage Solution for L-Shaped Pool House Yard

New Orleans L-shaped yard trapped by house, pool deck, and driveway floods from steep roof runoff. Yard sunk 5" relative to hardscape. Bilge pump in catch basin fails intermittently.

Need: photos for accurate design. Solution likely combines: regrade yard to drain toward street (2' lower), install perimeter French drain at house foundation, connect to gravity outlet if slope permits, or reliable sump pump with battery backup and alarm.

Cool deck and driveway act as dams—may need drainage cuts or permeable replacement sections. Roof runoff volume requires calculated pipe sizing.

Email photos to designer for integrated civil/landscape solution. This exceeds DIY scope.
