I was wondering if anyone works in the field or could give me some good advice on the correct way to fix a old soggy back yard. We recently moved into a half acre lot with a 1940's block house on a slab and the back yard is in very bad shape. My neighbors on both sides told me that several years ago they both added drainage to their back yards but ours was not done, both of their yards "look" to be about the same level as mine or close to it but ours is very unlevel and has standing water all throughout and is slow draining which looks to me to be more evaporation than draining. The neighbor on one side says his buddy does concrete and is always looking for a yard to dump fill dirt and he said he thinks i need some fill before thinking of topsoil. From what little i know about doing drainage tile I would think the correct way to do it is till and level the yard first, then dig trenches in the backyard, lay gravel in the trenches and preferated tile on top the gravel sloping toward the house and then back fill the trenches and level the back yard with top soil. We do have tile around the house going into the storm drain system I was told (we have 8inch. PVC "stubs" sticking out of the ground by the house with caps on them but I have no idea where they are run) but I dont know where I would tap the back yard tile into it (or if the city would flip out if i did). I also wondered if just leveling out the back yard and adding some top soil may correct the issues and while I appreciate the offer of the free fill I dont want to make a bad problem worse by dumping a bunch of unknown possibly "dirty" fill on top of an already non draining yard. Thanks in advance any thoughts, suggetions or tips as they will be greatly appreciated and again sorry for the long boring story.
