One of my clients has a small ditch in her back yard that is supposed to drain down through the neighbors' yards as well. Naturally, it doesn't work as it should and water ends up standing in her yard for quite a while. The back yard is lower than the front, so I don't think it could simply be drained to the street (approx. 50 yards). I'm not a landscaper or engineer, but the only thing I could think of was to get a small pump and pump it to the road and let it drain off there. I guess you could bury a small pipe from the pump if it needed to be more permanent. Any other ideas? Thanks.
