This area is low land that really has nowhere to drain to. Any ideas of how to help the area from staying flooded for so long after rain? I was wondering if topdressing a inch or so of sand would help it drain better. any thoughts? see pictures. The area slopes downward towards the truck way in the back of picture 1 ,and levels off and pools. I can do a rain garden for some areas but don't know how or if at all can help the large level areas.
