(a) Major Slopes. The average slope of each cut surface resulting in a major slope shall not be steeper than two horizontal to one vertical exclusive of benches and exclusive of roundings unless:
(1) a report is received from a soil engineer certifying that he or she has investigated the property and that in his or her opinion the proposed steeper slope will be stable and will not endanger any public or private property or result in the deposition of debris on any public way or interfere with any existing drainage course; and
(2) a report is received from a landscape architect certifying that such steeper slope, considering the nature of the soils on the slope surface, will support the proposed planting by maturity without significant or excessive erosion.
All major cut slopes shall be rounded into the existing terrain to produce a contoured transition from cut face to natural ground and abutting cut or fill surfaces where conditions permit. The County Official may require at any time that the excavation be made with a cut face flatter in average slope than two horizontal to one vertical or require such other measures as he or she deems necessary for stability and safety.
(b) Minor Slopes. Cuts resulting in minor slopes shall not be steeper in slope than one and one half horizontal to one vertical unless the County Official approves such steeper slope after receipt of a report by a soil engineer certifying that he or she has investigated the property and that in his or her opinion the proposed steeper slope will be stable and will not endanger any public or private property or result in the deposition of debris on any public way or interfere with any existing drainage course.
(c) Borrow Pits. The application of this section to borrow pits shall be limited to the final slopes thereof.
