dc.descriptionTrends of increasing wildfire size and severity across the western U.S. and concurrent encroachment and development into the wildland-urban interface place more people and infrastructure at greater risks from wildfires and the aftermaths of fires. Wildfires dramatically alter watershed hydrologic conditions, substantially increasing the potential for post-fire floods and debris flows. To further complicate matters in the Southwestern U.S., the wildfire season often ends at the onset of monsoonal rainfall, which may ultimately extinguish wildfires while producing large floods and debris flows in the immediate aftermath of a fire. This allows for very little time to assess post-wildfire damages and hydrologic changes, and to implement mitigation measures. This phenomenon was highlighted in 2010 by the human-caused Schultz Fire on the Coconino National Forest northeast of Flagstaff, Arizona. Following the fire, heavy rains resulted in numerous debris flows, significant erosion, and substantial flooding which caused extensive damage to residential neighborhoods, homes, property and infrastructure up to four miles from the burn area. The aftermath of the Schultz Fire illustrates the challenges many developed areas have dealing with post-wildfire flooding and debris flows. This study consisted of a countywide reconnaissance-level evaluation to identify areas that are at risk for flooding and debris flows in the aftermath of a reasonable-scenario wildfire, and more detailed planning-level evaluations of post-fire flood and debris flow hazards for two pilot study areas in Fort Valley and the City of Williams.
