C. If the changes requested by the applicant are acceptable, the city will issue an amendment to the grading permit. Cuts. (a) Generally. Unless otherwise recommended in the approved soils engineering and/or engineering geology report, cuts shall conform to the provisions of this section. In the absence of an approved soils engineering report, these provisions may be waived by the city for minor cuts not intended to support structures. (b) Slope. The slope of cut surface shall be no steeper than is safe for the intended use and shall be no steeper than three horizontal to one vertical (3:1), for a short term interim period, unless the owner furnishes a soils engineering or an engineering geology report, or both, stating that the site has been investigated and giving an opinion that a cut at a steeper slope will be stable and not create a hazard to public or private property. Unless specifically approved, permanent slopes shall be no steeper than three horizontal to one vertical (3:1). (c) Drainage and terracing. Drainage and terracing shall be provided as required by the Engineering Design Guidelines. Fills. (a) Generally. Unless otherwise recommended in the approved soils engineering report, fills shall conform to the provisions of this section. In absence of an approved soils engineering report, these provisions may be waived for minor fills not intended to support structures. (b) Clearing area to be filled. All timbers, logs, trees, brush and rubbish shall be removed from the site. No burning of the debris will be allowed unless a burning permit is issued by the city. (c) Preparation of ground. The ground surface shall be prepared to receive fill by removing vegetation, noncomplying fill, topsoil and other unsuitable materials. The ground shall be scarified to provide a bond with the new fill and, where slopes are steeper than five to one (5:1) and the height is greater than five (5) feet, by benching into sound bedrock or other competent material as determined by the soils engineer. The bench under the toe of a fill on a slope steeper than five to one (5:1) shall be at least ten (10) feet wide. The area beyond the toe of fill shall be sloped for sheet overflow or a paved drain shall be provided. When fill is to be placed over a cut, the bench under the toe of fill shall be at least ten (10) feet wide but the cut shall be made before placing the fill and accepted by the soils engineer or engineering geologist or both as a suitable foundation for fill. (d) Fill material. Organic material shall not be permitted in building pad or roadway areas. Except as permitted by the city, no rock or similar irreducible material with a maximum dimension greater than twelve (12) inches shall be buried or placed in fills. Exception: The city may permit placement of larger rock when the soils engineer properly devises a method of placement, continuously inspects its placement and approves the fill stability. The following conditions shall also apply: (1) Prior to issuance of the grading permit, potential rock disposal areas shall be delineated on the grading plan. 8
