My garden backs onto a bridge which has a steep slope leading to a high ground just above my garden. That's to say, my garden is low down. I am thinking of levelling the high bank of soil/hardcore, to my garden level. Before I do that, I want to secure the steep slope just below the bridge. There are few small Sycamore trees. The roots of these should stop the soil from washing down in the rain. I hope to have a mini digger to push excess soil against the steep slope. Is there anything I need to do to secure this area before I level the area?
