Answer: Controlling drainage and surface runoff and directing water is a highly specialized expertise and requires professional training and on-site inspection prior to suggesting how to deal with such a problem. For help in designing a system you might contact a degreed landscape architect or other licensed and certified professional with training in grading and drainage work. Your county extension (397-6000) might also have some background information about such systems that you would find useful. I'm sorry I can't be more helpful.
