I purchased my home one year ago and when it rains for an extended period of time, a river flows through my backyard. My As you can see from the picture, the homes to the right of my house have yards that are elevated. The street is shaped like an inverted bow and my home is near the middle.
In picture 1, my neughbor's yard begins five feet to the left of the picnic table. He has the stream flowing through his yard. The stream opens up into a lake when it reaches my yard.
Would a french drain placed at the mouth of the stream be able to handle that much water? I could run it to the rear of my property. Or could I use a bobcat and make a shallow trench and direct the water to the street- located past the trees to the rear of the property?
I have a contartor willing to give me a very large quantity of dirt to address the low areas in the yard which can be seen in the other pics.
A few musts IMO.
First, make sure the grade around your house enables all water to run AWAY from your foundation. TRhen make your trench, swale, out to the street. These two things should be done together. Normally 1/4" per foot is OK for the grade around your house. In your situation I would try and make it even more pronounced.
Hire out a guy with a bobcat to do the work. You may or may not need the fill dirt.
Worst thing you could do would be to dump that dirt only to just redirect the Yangtze closer to your house.
Also, consider integration of gutters into your plan if possible.
