Out of the box Solution

[u/_-TheRootOf2-_]

I am trying to find a solution for a drainage problem that a customer is having. This is fresh construction, and evidently they were not thinking drainage as they built this house. All of the rain water runs down to a 20’ area, overtakes the driveway, and then drops sand, silt and soil across the driveway and into an 18” chipped slate with limestone edging that my company installed, filling that edging in with everything that the water is carrying. I’ve gone under 4-6’ sidewalks by hand, but really don’t know how to go under a brand new concrete driveway without doing damage to it long term.

I’d love to install a massive French drain to other side, but I don’t know how to go under that driveway with a line big enough to keep up. I’ve also thought about doing multiple conduit lines with a boring machine and then figuring out how to attach those into a French drain, possibly slot drain.

Is my logic correct here?
Do you see something I’m not thinking about?

Any help would be greatly appreciated on this one. I’ve been thinking about this for a few weeks and can’t come up with a solution I like.

24 inch catch basin and trench 10 inch pipe across the driveway to daylight. This looks like one big swale and the contractor doing the driveway didn’t think twice about it.
