To take care of the sloped backyard, we created a boulder retaining wall over 50 feet long that curved around one fence line. This created an upper area that was flat for the in-ground trampoline. In the lower area we created the gas fire pit with a sitting wall with several large 2’ to 4’ boulders to help retain the dirt on the slope. In the southernmost part of the yard we placed the shed pad and garden boxes (for maximum sun!).
