Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to grade a site by hand [title] Choose your grade. [step] There are three ways to go here. Either cut straight back into the hillside, and use retaining walls behind the structure to hold the earth back.

Ending1: Or put retaining walls around the lower side of the site, and build up with fill. You will be ordering at least a truckload of dirt here (not that costly, under a $100), and once it's in, it will need a month or so to properly settle. Ending2: Use a masonry saw and a scraper to cut straight down the hillside to either 6-12 inches (15-30 cm), below the ground at the bottom. When you have cut straight across, trace the bottom. Ending3: Again, cut back yourself into the riverbed, and have a friend navigate up and down the slope. Watch out for deer, and keep your attention on observing behavior. Ending4: You have several options here; done it before. Cut back into the hill at a 45 degree angle; this will remain straight and make walking even easier.
