One of the first thing we did was cut all this "stuff" out. The sidewalk was so overgrown it couldn't be seen and I'd decided enough is enough and we cleaned and leveled this area. Our Double lot rises maybe 15 feet in elevation from front to back. Ultimately we will have 4 distinct terraced levels on the lot with level changes in each terraced area.
Of course to clear the accumulated dirt that had washed down the hill and over our retaining wall we had to have a place to put it, and I did, the area north of our sunken garden area where the Pond and waterfall will be. So to make the "hill" there I took the dirt from the street level area and with a wheelbarrow moved it.
This meant taking the wheelbarrow up the hill on our side street entering the lot at the back driveway area ( because we have a hill by the side street too steep to get the wheelbarrow up), then back down to the middle of the lot to deposit the fill where I needed it. By my calculations each trip with the wheelbarrow full of dirt was 350 feet and most of it, up hill!
