(A) Height. No manufactured slope may exceed a vertical height of 25 feet unless a higher slope is required for a public street, or unless approved by the Planning Commission or City Council through the review and approval of a tentative tract map. The height of a manufactured slope must include the height of any retaining wall constructed as an integral part of the slope.
(B) Slope. No manufactured slope angle may be steeper than 2:1 unless approved by the City Engineer or Building Official, based on studies provided by the applicant demonstrating that:
(1) Special circumstances applicable to the property, including size, shape, topography, location, or surroundings, deprive the property of development opportunities otherwise available to properties in the same zone; and
(2) Data provided by a soils engineer, engineering geologist, and landscape architect support the contention that the slope material and material underlying the slope are capable of permanent stability at an angle steeper than 2:1, and that the required slope planting can be adequately maintained.
(C) Location of lot line. Any manufactured slope occurring on a side or rear lot line must be made a part of the downhill lot.
(D) Cut slopes in rock. Manufactured cut slopes in rock material must be provided with soil pockets or cut terraces to facilitate the planting of landscaping.
