I think Elaine's suggestions are good. I probably should have said that if they choose to deflect the water, deflect it to a city drain, approved run-off course, etc. I know of someone who ran into legal issues when they deflected the runoff back onto the person's property that caused the runoff in the first place. Unbelievable but true! They eventually prevailed in court but it was an ugly situation for a while (and stressful for the individual involved).
