(A) Not more than 5% of a lot, parcel or planned development site shall be left with a cross slope steeper than the natural grade of the ground or steeper that 25% whichever is greater.
(B) The total area of all cuts and fills, not including the enclosed floor area of the dwelling, shall not exceed 15% of the lot, parcel or planned development site area.
(C) Maximum height of structure must conform to the zoning for its district and is determined by measuring vertically from the natural grade at the lowest point adjacent to the structure to the highest point of the structure. (See § 154.089(B) of this chapter.)
(D) The highest point of the structure must not extend above a 20-degree angle of declination from the nearest ridgeline, rock outcropping or other prominent visible feature. (See § 154.089(B).)
(E) Cut or fill slopes shall be entirely contained within the lot disturbance envelope during construction and when final grading is complete.
(F) All excavated materials which are to be retained on site in accordance with an approved grading plan shall be suitably landscaped, contained behind retaining walls or placed so that the slopes of any exposed fill material will not exceed 25% and will not exceed four feet in height.
(G) (1) Engineered grading plans are required where cut or fill exceeds four feet in height and walls are required for slope stabilization/containment.
(2) No retaining wall shall exceed eight feet in height and 100 linear feet in length.
(H) Retaining walls including their footings must be engineered.
(I) Cut and fill slopes shall be provided with subsurface drainage as necessary for stability.
