Subject:
Soil compaction for rear slope at the above address
th
The filled slope on the rear of the subject site was performed on Friday June 19, 2015.
Visual observations a
filled slopes. All of the soil is firm and stable, 20 locations were sampled for load bearing
capacity with the penetrometer. 19 of the 20 places indicated bearing capacity in excess of 2000
lbs per square ft, which corresponds to 95 percent or better compaction. The imported fill is an
excellent mixture of clean sand and gravel, good for the purpose of slope filling and good
compaction properties.
There was also imported top soil already on site, ready to be spread over the fill in preparation
for the cover planting as required for permanent erosion control.
