This job is a relatively simple job. We have an eyesore ditch in front of our house. This job would require building a very simple, short retaining wall right along the house side of the ditch in the front yard area. I'm thinking 2ft above ground and 1ft underground. A trench would be dug big enough for interlocking wall blocks to be placed into. Perhaps steel rods would be place inside the interlocking blocks to reinforce them, since this project is on a sloping front yard.
