In order to protect adjacent property owners from possible damage due to changes in existing grades, there shall be a five-foot grassy buffer surrounding the fill area including the front, rear and side yards. No change in the existing topography within 25 feet of the property line shall result in the slope to a ratio greater than five horizontal to one vertical. In no case shall any slope exceed the normal angle of slippage of the soil involved and no fill shall be placed in the five-foot grassy buffer area. The total elevation change shall not exceed the total elevation of the maximum slope ratio. The exception to this shall be where retaining walls are built with the written consent of the abutting property owner and with the approval of the Planning Commission and County Board.
