1. BUILDING STRONG SM Portland District Flood Damage Reduction Making Stormwater Management Systems Reduce Flood Damages D. Leslie Miller, P.E. Flood Preparedness Program Manager

2. BUILDING STRONG SM Portland District Fighting Floods – “So what” Factor…. March 2008 Cape Girardeau, MO successful flood fight – raised levee height with sandbags May 2001 Davenport, IA successful sandbagging flood fight of John O-Donnell Stadium May 2002 Crystal City, MO successful sandbagging flood fight of Dairy Queen

3. BUILDING STRONG SM Portland District Perspective Keep rain as close to where it falls…even when it exceeds stormwater retention system designs…. Design system so they can safely retain a much larger volume of run off…by using emergency operations….

4. BUILDING STRONG SM Portland District Basics Design Plan Rehearse

5. BUILDING STRONG SM Portland District Basics – Why, where, what, when, how and who … Flood Fight Design & Plan…then Rehearse…. Right & legal priority Specific location & access (Real Estate agreements) Coordinated Emergency Operations Warning & triggering Collaborative design Identified Resources Assigned Responsibilities Remember to cover preparation, prevention, response and recovery Link it to permanent mitigation

6. BUILDING STRONG SM Portland District Some reasons for designing a stormwater system to accommodate emergency operations Provides an opportunity to convert new flood science, technology, historical and anecdotal accounts into a cost, time and resource effective way of reducing flood related damages Becomes part of community flood fight design and plan Allows neighbors to contribute (planning, training, exercising, stockpiling…placing…removing) Builds a collaborative vision (changes stagnant feature into dynamic possibilities) Increases chance of successfully reducing flood damages beyond the stormwater system

7. BUILDING STRONG SM Portland District Stormwater system design considerations to accommodate emergency operations Modifications to new and existing retention structures Assess how much increase storage capacity is available Embankment vs. walls Natural vegetated crowns vs. four season surface Width of crown for access and placement of temporary height and length extention Include worst case assumptions about material and processes used to place and remove the temporary structure Spillway or overtopping back slope protection
