I looked at a residence recently that is having drainage problems. Here's what I saw: The carport slab had been enclosed to make a garage so 'raw' cinderblocks were sitting on the slab which was about even with the grade of the side yard. A landscape bed with lots of mulch had been installed against the block. When it rains, water goes into the garage (big surprise) and the homeowner put a sealer coat on the inside so now the water can't escape back outside. He has had various 'experts' out to view this situation and was advised to have the landscape bed lowered. That's easy enough except that the grade beyond the bed is equal or slightly higher than the slab so getting positive flow away from the slab will be minimal.
Also, a major portion of the house roof drains into the gutter on this problem side of the garage. I recommended going to a six-inch gutter there. The back yard has some fall so water can be routed that way.
I can certainly install ADS lines but I'm wondering if there is more that should be done?
