This customer is having issues with growing grass in his backyard because of the drainage. As you can see, that back area is all dirt and he's saying the water is just laying there with nowhere to drain. Now, I've never done anything with drainage before so I'm not sure exactly how to go about this. Do I just need to raise the soil up towards the back? If so, how would I do that with his shed being there? Do I need to install some sort of drainage pipe? I would say from the back of the house all the way to the area where there is no grass, the elevation drops about a foot. Would I just grade the entire yard??
