Some topsoiling has been done in conjunction <br />with the layback. <br />Storm Damages <br />(added in 1999): The large and devastating storm that caused <br />extensive damage throughout the Arkansas River Basin did <br />significant damage to the Pikeview Quarry. In fact, for a period <br />the quarry was closed due to blockage of the access road above <br />the office. Employees were trapped in the quarry for a time <br />until they could work through the mudslide. <br />Three areas were affected. There were a number of small slumps <br />along the access road leading into the quarry. There was also a <br />slump of a reclaimed area on the south end of the quarry. But <br />the major damage was a huge mudslide and slope failure of a fill <br />slope above the roadway leading from the office to the quarry. <br />Many hundreds of cubic yards of fill became saturated due to <br />accumulation of water in the plant area. This basically <br />liquefied the fill material causing it to flow across the road. <br />No damages outside the permit area occurred as all of the mud <br />flow was contained within existing sediment control structures. <br />However, it took many days to remove the material. The material <br />was deposited on the salt dome structure to be used by the City <br />of Colorado Springs. That structure is essentially completed now <br />rather than seeing a slow expansion over the next few years. <br />Interestingly, slopes highly similar to the one that failed <br />showed no effects from the storm. The failure was due to a <br />localized topographic configuration behind the slope which <br />caused extensive seepage into the slope. Other slopes that <br />showed no effects had much better drainage. <br />This entire area will need to be repaired in the future, but due <br />to continued seepage and high levels of moisture in the non- <br />failed slope areas no repair can be done until the entire slope <br />dries out more. When repair is effected a different drainage <br />pattern will be established behind the slope so a repeat event <br />will not occur. <br />UPDATE 2000: The storm damaged area from last year <br />has not been repaired yet. However, considerable <br />effort was expended on cleaning basins at the base of <br />the large slump. More difficult has been the cleaning <br />of the culverts.
