Flood Plain Management & Hazard Mitigation Task Force Report, August 2008

The Flood Plain Management and Hazard Mitigation Task Force emphasizes the long-term benefits of mitigation and management to the entire state in preventing or reducing damages from floods and other hazards faced in Iowa. Investments in efforts to manage watershed areas and to mitigate any damages from floods or other disaster events benefit individuals, families, communities, agriculture, business and industry, and certainly public entities and infrastructure. The Task Force encourages the Rebuild Iowa Advisory Commission to balance the immediate needs for rebuilding to include the beginning of the investments required to effectively mitigate future damage and maintain effective policy in Iowa’s watersheds. The significance of the damage seen in Iowa from the tornadoes, storms, and floods of 2008 include the loss of eighteen Iowans in disaster-related events. This alone should inspire investment in mitigation efforts for all hazards. Much of the damage resulting from the disasters can be tied to floodplain management and hazard mitigation, pointing the way toward enhanced efforts and new initiatives to safeguard lives, property, and communities’ economic health. Even so, it must be recognized that the weather events throughout last winter and spring added impetus to the rains and storms that ultimately resulted in record flooding. Some perspective must be maintained as planning progresses and significant investments in mitigation are considered to meet a specific level of safety and protection from future threats. The Task Force identified a number of issues, and four were agreed-upon as those with the highest priority to be addressed by the Task Force through a set of recommendations.

Flood-Plain and Channel Aggradation at Selected Bridge Sites in the Iowa and Skunk River Basins, Iowa, HR-350, 1996

Flood-plain and channel-aggradation rates were estimated at selected bridge sites in central and eastern Iowa using four aggradation-measurement methods. Aggradation rates were quantified at 10 bridge sites on the Iowa River upstream of Coralville Lake and at two bridge sites in the central part of Skunk River Basin. Measurement periods used to estimate average aggradation rates ranged in length from 1 to 98 years and varied among methods and sites. A direct comparison cannot be made between aggradation rates calculated using each of the four measurement methods because of differences in time periods and aggradational processes that were measured by each method.
