Huge deep drainage ditch (what to do?)
Our back yard is 36x27 but is completely useless to us. The grading in our backyard is just awful thanks to a deep drainage ditch at the back of our lot. The ditch is about 4-5feet deep at the most severe end and is a good 6-8 feet wide and it runs right though our yard.
We have always dreamed about filling in the yard somehow to level it and finally this year we had 5 landscaping contractors come by to take a look. All of them want to build an armor stone retaining wall around the entire back lot and fill the ditch in with gravel and weeping tiles. Then soil and sod on top.
Will this work? Is this even legal and will it handle the drainage during a storm? A good 20 homes drain through our lot.
One guy wanted to put the back retaining wall 3 feet from the fence and route the ditch in between the wall and fence. The problem with this is that there is a 5 foot drop my kids could fall into.
