(A) Cut and fill slopes shall be designed, constructed and maintained in a manner that will maximize stability and minimize erosion. Consideration shall be given to length and steepness of slope, soil type, upslope drainage area and groundwater conditions when determining appropriate drainage management and slope stabilization measures.
(B) Rock or similar irreducible material with a maximum dimension greater than eight inches, organic materials and construction and demolition debris shall be prohibited from fills, unless such fills are intended and approved by the City Manager as mass rock fills or disposal fills.
(C) Fills shall be compacted in eight-inch lifts to a density that is appropriate for the intended use. That density shall be determined by laboratory analysis of the fill material prior to its placement. The sub-divider shall be responsible for this laboratory analysis.
(D) The horizontal distance from the top and from the toe of an existing or proposed unrestrained cut or fill slope to the nearest existing or proposed structure, property line or paved surface shall be at least one-half the vertical height of the cut or fill, unless local geology or character of materials indicates that a different distance is appropriate. No land shall be graded, divider’s engineer and the County Engineer.
(E) The sub-divider shall have fill material tested by a responsible testing company at his or her expense. No land shall be graded, cut or filled so as to create a slope exceeding a vertical rise of one foot for each two and one-half feet of horizontal distance between abutting lots, unless a retaining wall, designed by a professional engineer, registered in the state, is provided to retain the graded bank.
