He then showed me how to grade the existing surface to the new calculated slope. Because he was going to add 2" of road base and 2' of decomposed granite, he needed the existing land graded to 4" below the final proposed surface. My job was to fine tune the grade making sure of its evenness, which needed some work. We also witnessed the arrival of the delivery truck which brought in the road base. We distributed the road base on top of the existing grade, which will later be topped by two additional inches of decomposed fine granite (ADA compliant). Finally, after having finished grading, we tamped down the soil to compact it.
Overall it was hard work, but fun!!
