  1. PRESENTATION SUMMARY • Introduction • Overview (M. Ryan) • Geography • Living with the Red (M. Clamen) • Conclusions and Recommendations • Accomplishment's • Improvements in Flood Forecasting (D. Luna) • Mitigation (Structural/non-structural/Policy/Legislation changes) • North of the Border • Manitoba (D. McNeil) • South of the Border • US Federal (J. DeHarnais) • US State—Minnesota (Dale Frink) • Summary • What’s next? (M. Ryan) • Questions Mitigation – US State

  2. MinnesotaFlood Response and RecoveryRed River Valley Prepared by: Kent Lokkesmoe Director Division of Waters Minnesota Department of Natural Resources Presented by: Dale Frink Mitigation – US State

  3. The 1997 flood changed attitudes. Minnesota Flood Hazard Mitigation Program began in 1989. It provides 50% state cost share for projects that will reduce flood damages. (For large projects in small communities, the state has picked up most of the local share.) Mitigation – US State

  4. Funding History for Minnesota’s Flood Hazard Mitigation Program Mitigation – US State

  5. Mitigation – US State

  6. April 24, 1997Flood Control Projects WorkOslo, MN Cost $2 million in 1983. Avoided $30 million in damages thru 2001. Mitigation – US State

  7. Farmstead Ring Dikes Constructed over 225 Farm Ring Dikes Ring Dike in Red River Valley Mitigation – US State

  8. > 15 ft > 15 ft Regulatory Flood Protection Elevation (RFPE) 1-foot freeboard (minimum) 100-Year Flood level (including stage increase) Fill Top of Bank of Channel or OHWL Typical water level Original Ground Flood Fringe Floodway Figure 2. Key Standards for Structures in the Flood Fringe NOTE: NOT TO SCALE! Floodplain Management Minnesota requires 1 foot of freeboard above the regulatory flood.. Mitigation – US State

  9. Level of Protection U.S. – 100 year flood elevation MN – 100 year +1 foot Netherlands Rivers with gradient – 250 yr Rivers – 1250 yr North Sea – 10,000 yr Mitigation – US State

  10. Observations • Money flows to disasters. • Recovery will take longer and cost more than you estimate. • Requiring a higher level of protection should be considered. • Flood Hazard Mitigation is cost effective. Mitigation – US State
