All cut and fill surfaces created by grading except for firebreak purposes shall be planted with a groundcover that is compatible with the natural ground covers in the local jurisdiction. Topsoils are to be stockpiled during rough grading and used on cut and fill slopes. When slopes too steep to support continuous groundcover have been permitted and in lieu thereof niches and ledges provided for planting, such slopes need not be planted with a continuous groundcover, but may instead be screened with vines and planting. Cuts and fills along public roads may be required to be landscaped so as to blend into the natural surroundings. All plant materials must be approved by the planning commission and zoning administrator prior to issuance of a conditional use permit. (Ord. 111 §1, amended, 1985; Prior code §12-107-6(F)(10))
