water runoff/foundation issues

We live in an old house on a hill. Our backyard has an even area about 20 ft. deep directly behind the house and then the yard begins an ever increasing incline uphill, quite significantly. The flat area of the yard is always muddy/marshy because of all of the runoff that comes downhill. There is also considerable shifting/settling of the house and we have been told it is due to this water issue. The only suggestion we've heard so far about how to remedy this is to dig trenches on either side of the house, run piping with drainage holes (kind of like a whiffle ball) in them and cover them with gravel with the idea being that the water would hit the trenches and run off into the street/gutter. Does anyone agree or disagree with this idea or have a better one?

Umm? Yes, that is quite common actually.

Susan,

These excavations are known as "curtain drains"---the idea is to build a trench 2' deep by 2' wide across the property facing the hill---the concept is to "intercept" the water as it comes down the hill and divert it using perforated drain pipe at the bottom of the trench to divert the water to the side of the property (if possible), or to continue the drain pipe to the front of the property if street sewers are available.

If DIY, a backhoe, either walk-behind or full size, is rented or contracted to dig the trench---the drain laying and backfill can be done by hand.

Google "curtain drain" or "soggy yard" for numerous sites that treat this topic.

Thanks so much for the response. Knowing the term "curtain drain" made searching for info. significantly more productive!
