<br />MITIGATION ISSUES <br /> <br />The main purpose of identifying both short-term and long-term mitigation measures for the Buffalo <br />Creek watershed and the community's infrastructure is to prevent future loss of life and reduce <br />losses and damages to property. Those at risk in the watershed include local residents, emergency <br />and post-flood workers, recreationists (fishing, biking, camping" etc.), and highway users. Some of <br />the mitigation issues are provided in the lists below. <br /> <br />Short- Term Issues <br />. Define the immediate hazards to life and property <br />. Address or partially address those hazards as soon as possible <br />. Establish how the community's water supply will be reconstructed and with what money <br /> <br />Lonl!- Term Issues <br />. Define the long-term hazards to life and property <br />. Define strategies that could be considered for life safety and property protection (i.e. waming <br />systems, erosion control, design/regulatory standards for rebuilding, etc.) <br />. Establish who should implement those strategies, and with what money <br />. Determine approach to provide more lead time for flash-flood warnings <br />. Determine likelihood of more flood-producing rainstorms <br />. Determine the potential for debris flow/mud flow <br />. Determine the rainfall amounts and conditions that produce flash floods in the burned areas <br />. Determine the need for new stage and precipitation gages in headwater areas to enhance flood <br />forecasting <br />. Determine the runoff potential for burned versus unburned areas <br />. Provide the National Weather Service and the Urban Drainage and Flood Control District with <br />locations of recent fire-burned areas; Link those areas with radar data for advanced flood <br />forecasting <br />. Assess the appropriate level of public day use in and downstream of fire-burned areas <br />. Determine the type and placement of flash flood warning signs <br />. Determine the most cost-effective sediment and water mitigation measures <br />. Determine maximum flood potential for burned and unburned areas using paleoflood <br />techniques <br />. Monitor the long-term sedimentation and/or degradation in various reaches of the affected <br />streams <br /> <br />Post-Flood Photol!raphs <br /> <br />Photographs are provided on the following pages to represent some of the important Issues <br />concerning mitigation activities. <br /> <br />a <br />
