Please excuse all the junk on the ground. My sideyard came with a swathe which leads to this outlet built into the wall. I ultimately want to flatten this and put a small shed or raised garden. I understand this will ruin the drainage setup…should I install a french drain which outlets to/through this existing outlet built into the wall? Something else?
