According to the article by Ms. McGregor, the effort apparently <br />paid dividends as evidence of retained mud was visible on the hillsides. <br /> <br />The Coal Seam Fire was a unique factor that affected the storm event analyzed in this <br />report. In fact, it is reasonable to conclude that the damage from this fire caused, or at <br />least increased, the effects from the storm. The hydrologic conclusions suggest this storm <br />was a common storm experienced by Glenwood Springs occurring on a semiannual basis. <br />It is also reasonable to conclude that under pre-fire circumstances, minimal flooding or <br />mud damage would have occurred because of this event. <br /> <br />The fire destroyed most of the vegetation in the area and charred the remaining soil. With <br />the loss of vegetation, came the loss of anything to hold the soil in place. When the soil <br />was burnt, it lost most of its ability to absorb any water and this, combined with the loss <br />of vegetation, increased the runoff, which worsened the impacts ofa flood. <br /> <br />ICO~ Engireering, Inc <br /> <br />45 <br /> <br />January 2003 <br />
