STEP 14
BRING IN THE TOPSOIL
• Add topsoil to the berm and surrounding area in order to
provide a good substrate for future landscape planting.
STEP 15
BUILD THE RETAINING WALL
• Finish off the berm where the Biofall is buried by building a
small retaining wall out of boulders. This step may or may
not be needed, depending on the size of the berm and the
transition into the existing landscape.
