The top of cut slopes shall not be made nearer to a site boundary line than one fifth of the vertical height of cut with a minimum of 2 feet (610 mm) and a maximum of 10 feet (3048 mm). The setback may need to be increased for any required interceptor drains Top of Fill Slope. The toe of fill slope shall be made not nearer to the site boundary line than one half the height of the slope with a minimum of 2 feet (610 mm) and a maximum of 20 feet (6096 mm). Where a fill slope is to be located near the site boundary and the adjacent off-site property is developed, special precautions shall be incorporated in the work as the Building Official deems necessary to protect the adjoining property from damage as a result of such grading. These precautions may include but are not limited to: 1. Additional setbacks. 2. Provision for retaining or slough walls. 3. Mechanical or chemical treatment of the fill slope surface to minimize erosion. 4. Provisions for the control of surface waters Modification of Slope Location. The Building Official or designee may approve alternate setbacks. The Building Official or designee may require an investigation and recommendation by a qualified engineer or engineering geologist to demonstrate that the intent of this section has been satisfied. SEC DRAINAGE AND TERRACING General. Unless otherwise indicated on the approved grading plan, drainage facilities and terracing shall conform to the provisions of this section for cut or fill slopes steeper than 1 unit vertical in 3 units horizontal (33.3% slope) 23

24 Terrace. Terraces at least 6 feet (1829 mm) in width shall be established at not more than 30-foot(9144 mm) vertical intervals on all cut or fill slopes to control surface drainage and debris except that where only one terrace is required, it shall be at midheight. For cut or fill slopes greater than 60 feet ( mm) and up to 120 feet (36 576mm) in vertical height, on terrace at approximately midheight shall be 12 feet (3658 mm) in width. Terrace widths and spacing for cut and fill slopes greater than 120 feet ( mm) in height shall be designated by the civil engineer and approved by the Building Official or designee. Suitable access shall be provided to permit proper cleaning and maintenance. Swales or ditches on terraces shall have a minimum gradient of 5 percent and must be paved with reinforced concrete not less than 3 inches (76 mm) in thickness or an approved equal paving. They shall have a minimum depth at the deepest point of 1 foot (305 mm) and a minimum paved width of 5 feet (1524 mm). A single run of swale or ditch shall not collect runoff from a tributary area exceeding 13,500 square feet ( M2)(projected) without discharging into a down drain Subsurface Drainage. Cut and fill slopes shall be provided with subsurface drainage as necessary for stability Disposal. All drainage facilities shall be designed to carry waters to the nearest practicable drainage way approved by the Building Official or designee or other appropriate jurisdiction as a safe place to deposit such waters. Erosion of ground in the area of discharge shall be prevented by installation of non-erosive down-drains or other devices. Building pads shall have a drainage gradient of 2 percent toward approved drainage facilities, unless waived by the Building Official or designee. EXCEPTION: The gradient from the building pad may be 1 percent if all of the following conditions exist throughout the permit area: 1. No proposed fills are greater than 10 feet (3048 mm) in maximum depth. 2. No proposed finish cut or fill slope faces have a vertical height in excess of 10 feet (3048 mm). 3. No existing slope faces steeper than 1 unit vertical in 10 units horizontal (10% slope) have a vertical height in excess of 10 feet (3048 mm) Interceptor Drains. Paved interceptor drains shall be installed along the top of all cut slopes where the tributary drainage area above slopes toward the cut and has a drainage path greater than 40 feet ( mm) measured horizontally. 24

25 Interceptor drains shall be paved with a minimum of 3 inches (76 mm) of concrete or gunite and reinforced. They shall have a minimum depth of 12 inches (305 mm) and a minimum paved width of 30 inches (762 mm) measured horizontally across the drain. The slope of drain shall be approved by the Building Official or designee Slopes. The faces of cut and fill slopes shall be prepared and maintained to control against erosion. This control may consist of effective planting. The protection for the slopes shall be installed as soon as practicable and prior to calling for final approval. Where cut slopes are not subject to erosion due to the erosion-resistant character of the materials, such protection may be omitted Other Devices. Where necessary, check dams, cribbing, riprap or other devices or methods shall be employed to control erosion and provide safety. SEC GRADING INSPECTION General. Grading operations for which a permit is required shall be subject to inspection by the Building Official or designee. Professional inspection of grading operations shall be provided by the civil engineer, soils engineer and the engineering geologist retained to provide such services in accordance with Sec for engineered grading and as required by the Building Official or designee for regular grading Civil Engineer. The civil engineer shall provide professional inspection within such engineer s area of technical specialty, which shall consist of observation and review as to the establishment of line, grade and surface drainage of the development area. If revised plans are required during the course of the work they shall be prepared by the civil engineer Soils Engineer. The soils engineer shall provide professional inspection within such engineer s area of technical specialty, which shall include observation during grading and testing for required compaction. The soils engineer shall provide sufficient observation during the preparation of the natural ground and placement and compaction of the fill to verify that such work is being performed in accordance with the conditions of the approved plan and the appropriate requirements of this chapter. Revised recommendations relating to conditions differing from the approved soils engineering and engineering geology reports shall be submitted to the permittee, the Building Official or designee and the civil engineer. 25

26 Engineering Geologist. The engineering geologist shall provide professional inspection within such engineer s area of technical specialty, which shall include professional inspection of the bedrock excavation to determine if conditions encountered are in conformance with the approved report. Revised recommendations relating to conditions differing from the approved engineering geology report shall be submitted to the soils engineer Permittee. The permittee shall be responsible for the work to be performed in accordance with the approved plans and specifications and in conformance with the provisions of this code, and the permittee shall engage consultants, if required, to provide professional inspections on a timely basis. The permittee shall act as a coordinator between the consultants, the contractor and the building official or designee. In the event of changed conditions, the permittee shall be responsible for informing the building official or designee of such change and shall provide revised plans for approval Building Official or designee. The Building Official or designee shall inspect the project at the various stages of work requiring approval to determine that adequate control is being exercised by the professional consultants Notification of Noncompliance. If, in the course of fulfilling their respective duties under this chapter, the civil engineer, the soils engineer or the engineering geologist finds that the work is not being done in conformance with this chapter or the approved grading plans, the discrepancies shall be reported immediately in writing to the permittee and to the Building Official or designee Transfer of Responsibility. If the civil engineer, the soils engineer, or the engineering geologist of record is changed during grading, the work shall be stopped until the replacement has agreed in writing to accept their responsibility within the area of technical competence for approval upon completion of the work. It shall be the duty of the permittee to notify the Building Official or designee in writing of such change prior to the recommencement of such grading. 26
