I need some help with a job. It's a drainage problem. I'll try to explain it the best that I can. The back yard is 32 feet long. There is a catch basin in the back corner of the yard. But nothing is going into it because it is above grade. The yard slopes towards the back fence but raises again before the fence, so all the water collects and there is about a 5 foot wide by 32 feet long spot that is always saturated with water. What can be done to correct this problem. Someone suggested putting down some stone with some pipe and running it into the catch basin and then re-sodding. Please help.
