Regardless <br /> of the time of year, all soils shall be stabilized at the end of the shift before a holiday <br /> or weekend if needed based on weather forecasts. <br /> In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles <br /> will be temporarily covered with plastic sheeting. All stockpiled soils shall be <br /> stabilized from erosion, protected with sediment trapping measures, and where <br /> possible, be located away from storm drain inlets, waterways, and drainage channels. <br /> July 2014 2-2 LDC Job No. 13-144 <br />
