(2) Provide an approved potable water supply for all employees. (3) Provide approved toilets for all employees (chemical toilets are acceptable). (4) Provide hand-washing facilities on or near the approved toilets. (Development Title Section 9-1415.3[i]) SETBACKS: No excavation shall take place within twenty-five (25) feet of any property line or right-of-way (nor within the allowed slopes adjacent to said twenty-five (25)foot setback), unless the elevation prior to excavation is more than that of the abutting property, in which case the elevation within said twenty-five (25) foot setback shall at no time be less than that of the abutting property, at the property line. (Development Title Section 9-1415.303) (1) Temporary Cut Slopes at Setback Lines. Temporary cut slopes (i.e., for limited periods of time, slopes that are in the process of extraction prior to being backfilled) at setback lines shall not exceed one (1) foot horizontal to one (1) foot vertical, except that temporary cut slopes at setback lines to a maximum of one half(1/2) of a foot horizontal to one (1) foot vertical may be maintained if site-specific geologic and engineering analysis demonstrate through a slope stability analysis that the proposed temporary cut slopes will have a minimum slope stability factor of safety as required in Section 9- 1415.3(k)(4). However, in the event that there are existing structures on the adjacent property (or the immediate potential for structures on the adjacent property), the excavation shall at no time be closer to the property line than a line projected on a slope of one(1)to one (1)from the property line to the toe of slope. (2) Final Slopes. Final cut and/or fill slopes shall not exceed two (2) feet horizontal to one (1)foot vertical. (3) Fill Slopes. Fill slopes shall be constructed consistent with recommendations from a qualified civil/geotechnical engineer based upon site-specific geologic conditions, j. FENCING: Fencing four (4) feet in height consisting of not less than three (3) strands of barbed wire, or an approved equivalent, shall be placed around the excavation area where slopes steeper than two(2) feet horizontal to one(1) foot vertical are maintained. Six (6)foot high security fencing or an approved equivalent shall be required where slopes steeper than two (2) feet horizontal to one (1) foot vertical are created, if the proximity of such slopes to residential uses or other uses involving a concentration of people so warrants. (Development Title Section 9-1415.3[11) k, SCREENING AND LANDSCAPING: Screening consistent with Chapter 9-1020 is required. (Development Title Section 9-1415.3[m]) (1) The landscaped area shall be ten (10) feet wide. Adequate setback for maintenance shall be required, and sight distance at road intersections shall not be impaired. A row of crop trees satisfies this requirement. I. EXCAVATION/RECLAMATION SCHEDULE: The reclamation plan shall show the phases of excavation. Reclamation on one phase of an excavation shall be initiated prior to the start of the next excavation phase. The final reclamation of any phase of excavation shall be completed within two years of the commencement of the reclamation process. Excavation shall be limited so that at any point of time a maximum of one phase is being reclaimed while one phase is being excavated. (Development Title Section 9-1415.3[0]) 3
