(A) General. Cut and fill slopes shall be set back from site boundaries in accordance with this section. Setback dimensions shall be horizontal distances measured perpendicular to the site boundary. Setback dimensions shall be shown on the grading plan.
(B) Top of cut slope. The top of cut slopes shall be made not nearer to a site boundary line than 1/5 of the vertical height of cut with a minimum of 2 feet and a maximum required setback of 10 feet. The setback may need to be increased for any required interceptor drains.
(C) Toe of fill slope. The toe of fill slopes shall be made not nearer to the site boundary line than ½ the height of the slope with a minimum of 2 feet and a maximum required setback of 20 feet. Where a fill slope is to be located near the site boundary and the adjacent off-site property is developed, special precautions shall be incorporated in the work as the city deems necessary to protect adjoining property from damage as a result of grading. These precautions may include but are not limited to:
(1) Additional setbacks;
(2) Provision for retaining or slough walls;
(3) Mechanical or chemical treatment of the fill slope surface to minimize erosion;
(4) Provisions for the control of surface waters.
(D) Modification of slope location. The city may approve alternate setbacks based upon an investigation and recommendation by a qualified engineer or engineering geologist stating that the intent of this section has been satisfied.
