** if I need to move this post, just let me know**
Our backyard slopes to a creek. We would like to use gabions as a retaining wall (maybe 4ft tall) to level off our yard and base for a wire fence. This video is my inspiration: https://youtu.be/wN8r6uD1uiw
Is a gabion as simple as build it, sticking with the 2:1 ratio (2ft means 1ft across) and fill it with heavy rocks?
Do I need to consider the weight of the dirt I use to back fill it?
We really want to DIY this, but I am concerned that we need the assistance of a landscape architect or civil engineer… Thoughts??
