Prior to the commencement or continuation of any excavation or extraction operations or the construction or use of any settling basin, a fence shall be constructed enclosing the area of the proposed or existing excavation or settling basin or the entire site, unless data submitted to the Planning Director for approval indicates that no substantial safety hazards exist. The fence shall be of a steel, chain link type and a minimum of six feet in height above the existing grade of property outside the fenced area. The bottom of the fence shall conform to the ground surface so as to prevent any opening between it and the ground surface exceeding four inches. Gates of the same material and height as the fence shall be installed at all points of vehicular or pedestrian ingress and egress. The gates shall be equipped with keyed locks and shall be kept locked at all times when not in regular use. The fence, gates and locks shall be maintained in good working condition and repair.
