12.1 Minimum grid lengths.
12.2 Details for fencing and other potential lateral loads from objects located above or within the reinforced soil mass.
12.3 Details for placement and compaction of a slope above the wall structure.
12.4 Stability of slopes above the wall.
12.5 Slopes above the wall must be compacted following the proper lift and compaction recommendation from the geotechnical recommendations. See chapter 6.0, Soils and Compaction.
12.6 Reinforcing the slope above the wall may be necessary to provide adequate stability to the wall system. Geogrid lengths typically matching the standard grid lengths in the wall along with their spacing are commonly used in walls with steep slopes above, greater than 3:1, and/or any slopes with poor soils or walls with seismic requirements.
12.7 Details for plantings located above the wall structure.
