I have attached some pics of a job I am doing. This guy added on to his house on both sides and it messed up how the yard drains... so I basically went in and dug it out and graded so that the water flow around the house. We got probably 1-2 inches of rain last night so I feel like the grading is pretty close. My question is about a french drain. I was thinking of putting a french drain in the bottom of the swell I made so that the bottom of the swell would dry out quickly, but my dirt guy(who grades for a living) said if I put french drain in... it needs to go against house and not in the bottom of the swell. That just doesn't make sense to me. What do you guys think?
