We have a backyard that floods every spring (and after any significant rainfall), killing a large portion of the grass. Please see the photo attached, which is from April 23. Our soil is mostly clay, and we are the lowest spot on the block so we get a lot of everyone else's runoff (per the topographic map from the Mississippi Watershed Management representatives that visited us). We do not know of a feasible way to add drainage to our backyard (running it to the street, or otherwise). We are looking for ideas of plants that would survive clay soil with frequent flooding, in order to soak up some water and try to rehabilitate the soil. We are also receptive to other ideas! Thank you!
You should be able to create a rain garden area that would serve to help with runoff and make the area attractive. I will give you links to info that you can look at and hopefully utilize. http://cleanwater.uwex.edu/pubs/pdf/rgmanual.pdf . http://www.extension.umn.edu/garden/yard-garden/landscaping/best-plants-for-tough-sites/docs/08464-r... . http://www.extension.umn.edu/garden/yard-garden/landscaping/best-plants-for-tough-sites/docs/08464-c... .
