18 Iowa Watersheds Project IWA built of the Framework of Iowa Watersheds Project Kickoff ( ) meeting follow-up August 2010, HUD announces $312M for Disaster Recovery Enhancement Fund (DREF) to 13 states in response to flood mitigation efforts Iowa received the largest grant of $84.1M of CDBG funds $10M allocated to watershed demonstration projects directed toward flood damage reduction and educational programming $8.8M set aside for watershed demonstration projects overseen by the Iowa Flood Center $800K was used to establish the first WMAs in Iowa 18

19 Iowa Watersheds Project Kickoff meeting follow-up Beaver Creek: 6 wetlands Otter Creek: 5 on-road structures, 19 farm ponds, 5 WASCOBS Soap/Chequest Creek: 22 farm ponds, 106 WASCOBS 19

20 Iowa Watersheds Project Beaver Creek Wetlands Increase flood storage by 141% Reduce peak flows near project outlets by 20-90% for small (10- year) and large (50-year) floods Reduce downstream peak flows on Beaver Creek by 10-30% for small (10-year) and large (50- year) floods Captures 40-86% of incoming nitrate that would otherwise enter Beaver Creek 20

21 Iowa Watersheds Project IWA Project Description Built off the framework of the IWP Establish a WMA Develop a hydrologic assessment and watershed plan Deploy monitoring equipment Work with project coordinators and volunteer landowners to implement projects that reduce the magnitude of downstream flooding and improve water quality Assess project benefits based on monitoring and modeling data 21

27 Modeling Develop and run watershed-scale hydrologic models (PIHM) to estimate watershed responses to rainfall events Modeler breaks the watershed down into manageable and representative user defined areas Simulate hydrologic processes using a physically-based approach Compare simulated results to observed hydrologic time series (e.g. streamflow) to assess model performance Quantify the impact of existing and potential BMPs Documentation 27

38 What is Flood Resilience? Flood resilience is the ability of a community within a watershed to plan and act collectively, using local capacities to mitigate, prepare for, respond to, and recover from a flood. 38

39 Communities can increase resilience through flood mitigation projects Prairie Wetland Oxbow Restoration Pond 39

43 Social resilience can be improved in all IWA watersheds Social Resources are community characteristics that facilitate collective action. The ability to trust, build partnerships, form social networks, and pursue collective learning are examples. 43

47 We connect with local community organizations partners to support local interest and create a sustainable approach for building community resilience 47

48 Our first partnership to increase community resilience was with the City of Dubuque Dubuque and Iowa Flood Center Resilience teams partnership = Social Resilience Assessment 48

49 Protecting underresourced populations improves resilience in our communities Lower-income people are among the least able to recover, yet they are often central to the economy and culture of a community. - THE INSTITUTE FOR SOCIAL AND ENVIRONMENTAL TRANSITION INTERNATIONAL 49
