Here's what I've got... my house is at the end of a cul-de-sac. The drainage ditch for the cul-de-sac flows down hill (naturually!) under my driveway to and underground pipe that takes it 150 feet or so downhill where it drains to a fairly steep slope.
Unfortunately, the underground pipe (some places it's PVC, others it's corrugated pipe) wasn't buried deep enough, so it has begun to break apart, creating nasty ankle turning holes in the yard. It's now to the point where enough soil has gotten into the underground pipe that it is clogged and the water comes out one of the holes instead of at the end of the line. So now it's dangerous and it's rough on the yard!
Here's what I'd like to do... at the culvert where the underground pipe begins, I'd like to replace the pipe, but only a short segment of it. The way my hill drops off, I could probably run about 30 feet of underground pipe at a reasonable grade and have the pipe drain in middle of my yard, onto a bed of rocks. I really don't want to get into the expense of running that pipe the entire 150', plus having to pay to dig deeper to lay the pipe at a proper depth for the entire length. Going the shorter route, I'd just have to dig up the shallow old pipe and fill that length in with dirt.
Any opinions on this? Is there something I'm not thinking of?
