Here is a frustrated home owner. Whenever it rains, the water flows down from his neighbors lawn and settles in his back yard? He wants to know how to prevent this from happening in his yard. The back lawn are all graded with a downard slope and the rain water flows to his back lawn. He thought about putting up a privacy fence. I said I didn't think that would work, the water would destroy the fence. In this developement the builders put sod in the front and did nothing to the back. So the home owners are left to do what ever they want in the back. In these photos of the back lawn shows water at the top of the photo coming from 4 houses away. What can be done to prevent rain water from flowing from his neighbors lawns, and settling in his back yard?
