My neighbors yard is higher than my yard by about 3'. His property slopes away from his house and towards my house. The grading around my foundation on that side is not correct (i.e. its pretty much level) so the water from his property ends up against my foundation during a bad rain (like what we just got in the Northeast).
Aside from correcting the grading at my foundation, I wanted to add a french drain. It would be about 10' from my foundation, basically at the low spot between his yard and where the grading from my foundation would end. I also have 2 downspouts to drain out on that side of the house, and I figured while I have the Kubota I might as well bury the downspouts too.
A couple questions......can I use the same trench for the downspout drainage and the french drain? I would keep them as separate pipes, but I wasnt sure if the downspout pipe would interfere with the correct operation of the french drain.
Also, any recommendations on fill material? We have what seems to be normal soil for the area........definitely little to no clay content. I was thinking just normal 3/4" gravel from the local stone company.
2 or 3" in the bottom of the trench, followed by 4" drain pipe (was going to use the PVC stuff, not the black flexible stuff), followed by enough of the same 3/4" gravel to fill the trench to within 2" of the yard, followed by a layer of sod so I dont have to look at the gravel forever.Does the plan seem OK? I know a lot of people recommend different fill materials, figured Id ask what everyone thinks.
Thanks!
