Ron,
As opposed to adding more soil that will just stay wet due to the drainage in that area we are going to add rock that is 3 to 4 inches in size. The rock will be placed from the basket down to the blue pipe. The rock will still allow for drainage and should provide a better surface to walk on. You not only have the water coming from the west but this area is at the bottom of the slope and gets a lot of drainage coming down the slope from Eldorado.
Thanks
