The right-of-way of every street and alley shall be graded to its full width. Prior to the commencement of grading, the entire right-of-way area shall be cleared of all stumps, roots, brush, and other objectionable materials and all trees not intended for preservation. Stumps, boulders, and other obstructions shall be removed to a depth of not less than two feet below the subgrade. Rock other than boulders, when encountered, shall be scarified to a depth of not less than 12 inches below the subgrade. Suitable material from street or alley cuts may be used in the construction of fills, approaches, or other places as needed. Excess materials (as, for example, soft clay and organic materials) shall be removed from the site. The fill shall be spread in layers not to exceed 12 inches in depth when loose, and shall be compacted by a sheep’s foot or rubber tired roller; provided, utility trenches and other locations not accessible to a roller shall be mechanically tamped. Where water is used to assist compaction, the water content shall not exceed optimum moisture.
