One of the reasons behind the run off stuff is to assert control. Example: a neighbor had landscaping done. The landscaper told me he would do some work in my yard if I let him go thru my side yard to carry some big bolders thru on a bobcat. I agreed. Part of the "Free" landscaping work he did was to divert the runoff from the yard he was working on the the other neighbors yard next door that also backs up to my property. It caused their patio to flood and run into their house. Luckily instead of going after me, they went after their next door neighbor that was officially having the work done. He had to redo my yard so stop the run off from being diverted and pay to have their carpet replaced.
