All streets, roads and alleys shall be graded to their full width by the subdividers so that pavements and sidewalks can be constructed on the same level plane. Due to special topographical conditions, deviation from these standards will be allowed only with special approval of the Planning Commission.
(a) Preparation. Before grading is started the entire right-of-way area shall be first cleared of all stumps, roots, brush and other objectionable materials and all trees not intended for preservation.
(b) Cuts. All tree stumps, boulders and other obstructions shall be removed to a depth of two feet below the subgrade. Rock, when encountered, shall be scarified to a depth of twelve inches below the subgrade.
(c) Fill. All suitable material from roadway cuts may be used in the construction of fills, approaches, or at other places as needed. Excess materials including organic materials, soft clays, etc., shall be removed from the development site. The fill shall be spread in layers not to exceed twelve inches loose and compacted by a sheep's foot roller. The filling of utility trenches and other places not accessible to a roller shall be mechanically tamped, but where water is used to assist compaction, the water content shall not exceed the optimum of moisture.
