Backyard Drainage We have a drainage issue with our backyard. No issue when the rain is mild to moderate. Only when the rain is quite heavy. At that point the water just pools and lays there. I've had two people bid on putting in a french drain. They both want to put in a box drain. Our yard is relatively small and I don't want to have a 12x12 drain in it. It's also not an every day problem. So I told them I'd prefer to have a buried french drain. They just told me that they weren't as confident with that and they really want to put in a box drain. Attached is a photo with sketches of what I have in mind. Once I get it to the gate then I can tie it into our downspouts which run all the way down to the street. I can put in plenty of slope in the drain. Is my idea wrong for any obvious reason? Do you have any suggestions for improvement or alternative?
