Back yard drainage
Our back yard slightly slopes to the center and towards the house. Water collects at the foundation (about 3-4 inches). Obviously I need to do something about it, but I'm not completely sure which route to take.
1. Add top soil and sand over time to build it up.
2. Create a french drain.
3. Pull up the sod in that area and build it up, put new sod down.
4. Regrade entire back yard.
