Rake the sand back with a 2×4, maintaining an even slope (Photo 11). Take care not to step in the sand or compress it. Use sand to feather the slight slope in the gravel to meet the level steps evenly. Check the sand height against the top step by laying a paver on it. The paver should sit about 1/4 in. above the step. It’ll tamp down later.
