Can I build multiple or terraced walls in order to stay at or under the maximum wall height?
Terracing is one method of retaining areas with a total wall height greater than 4′ (1.2m). The site of the second wall should be located behind the first wall at a distance of at least or greater than 2 times the height of the first wall under ideal soil conditions. By using this method, the weight of the second wall has very little to no bearing on the first wall. This method should be used only if each wall does not exceed 4′ (1.2m).
