I'm looking for some advice on what I can do to prevent runoff water from going into my neighbor's yard. I am an auto detailer so I am constantly washing cars in my driveway. The neighbor also parks his truck and RV camper in the dirt section of the yard. Here is a picture so you can see what I am talking about. :-) ![enter image description here](https://i.stack.imgur.com/IDwPb.jpg)
