(b) Top of Cut Slope. The top of cut slopes shall not be made nearer to a site boundary line
than one -fifth of the vertical height of cut with a minimum of two feet and a maximum
of ten feet. The setback may need to be increased for any required interceptor drains.
The top of the cut slope shall be finished as a rounded or bald head slope.
(c) Toe of Fill Slope. The toe of fill slope shall be made not nearer to the site boundary line
than one-half the height of the slope with a minimum of two feet and a maximum of
twenty 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 official deems necessary to protect the adjoining property from damage as a result
of such grading. These precautions may include, but are not limited to:

(a) Additional setbacks;
(2) Provision for retaining or slough walls;
(3) Mechanical or chemical treatment of the fill slope surface to minimize erosion;
