§ 15.12.080. Setbacks.

(a)

General. Cut and fill slopes shall be set back from the property lines in accordance with this section. Setback dimensions shall be horizontal distances measured perpendicular to the property line and shall be as shown in figure 15.12.080 unless substantiating data is submitted justifying reduced setbacks is recommended by soils engineering and engineering geology reports approved by the building official.

(b)

Top of slope. The setback at the top of a cut slope shall not be less than that shown in figure 15.12.080, or than is required to accommodate any required interceptor drains, whichever is greater. For manufactured slopes the grading design must be such that the property line between adjacent lots will be at the apex of the berm at the top of the slope. Property lines between adjacent lots cannot be located on a graded slope equal to five units horizontal to one unit vertical (20 percent slope).

(c)

Toe of fill slope. The setback from the toe of a fill slope shall not be less than that shown by figure 15.12.080. Where required to protect adjacent properties at the toe of a slope from adverse effects of the grading, additional protection, approved by the building official, shall be included. Such protection may include but shall not be limited to:

(1)

Setbacks greater than those required by figure 15.12.080;

(2)

Provisions for retaining walls or similar construction;

(3)

Erosion protection of the fill slopes;

(4)

Provision for the control of surface waters.

(d)

Alternate setbacks. The building official may approve alternate setbacks. The building official may require an investigation and recommendation by a qualified engineer or engineering geologist to demonstrate that the intent of this section has been satisfied.
