1. Riverine Erosion Hazards & Floodplain Management: An ASFPM White Paper ASFPM National Conference Louisville, Kentucky May 19, 2011

2. Presentation Overview ASFPM White Paper Process Background: The Status Quo Discussion Paper Overview Santa Clara River, St. George, UT 2005

3. What is a White Paper? It is: –A Policy Document –An Overview –A Summary –A First Step It is NOT: –A Research Project –A Technical Paper –A Detailed Methodology –A Fully Implemented Plan

4. ASFPM Discussion Paper Process ASFPM Arid Regions Committee –Initiate & Write Draft Paper ASFPM Committee Group State Chapters ASFPM Board –Approval? –Implementation as Policy –Recommended Actions Action by FEMA? Implementation by Communities? You are here

5. Problem Statement: Erosion of Homes Above the BFE Total Loss of Home AND Property Occurs Below Q100 Progressive Over Time Santa Clara River, St. George, UT 2005

6. Problem Statement: FEMA Recognizes Erosion as Problem –REHA (1999) NFIP Requires Erosion Zone Management –Part 60.5 (a) – Communities shall manage –Part 60.24 Erosion Not in Model Ordinance Erosion Not on FIRM Coverage of Erosion Losses Questionable Erosion Not in FEMA Guidelines

7. Problem Statement: Local Communities are Regulating Erosion –States: AZ, NH, VT –Communities: AZ, NM, TX, UT, WA –Erosion Setbacks –River Corridor –Varying Levels of Detail

8. Paper Overview Riverine Erosion is Important –Occurs Nationwide –$400M/yr in Damages (1999) –Especially Important in Arid West Goal: Improve Tools for Delineating & Managing Riverine Erosion

9. Paper Overview: Recommendations #1: Clarify NFIP Regulations for Erosion –Erosion Zones on FIRM Panels –Provide Insurance Coverage –Guidelines for Erosion Management –CRS Credits for Erosion Management

10. Paper Overview: Recommendations #2: Recognize Foundational Principles –One Size Does Not Fit All Each River is Unique –Delineation Techniques Account for Local Stream Characteristics –Methodologies Must be Repeatable & Defensible

11. Paper Overview: Recommendations #3: Add Direction to FEMA Guidelines & Specifications for Flood Hazard Mapping Partners –Assure a consistent standard #4: Develop New Methods to Quantify & Delineate Erosion Hazards –A variety of tools may be required

12. Paper Overview: Recommendations #5: Develop Management Guidelines & Recommendations for NFIP Communties –Best Management Practices –Mitigation Measures –Flood Warning –Delineation –Coordination with Multi-Objective Goals

13. Paper Overview: Recommendations #6: Develop Protocols to Assure Consistent Review –Engineering Design Guidelines –Review Checklists #7: Conduct Regular Training –Reviewer –Community Officials –Engineers & Planners

14. Paper Overview: Recommendations #8: Collect Better Documentation of Riverine Erosion –Damage Accounts –Photos, News –Central Repository #9: Explore Linkages Between Riverine Erosion & Insurance/Management –RiskMAP Multi-hazards –Understanding Risk

15. Where Do We Go From Here? ASFPM Committee Approval…Pending ASFPM Board Approval….Next Up Consideration by IPT? –FEMA, ASFPM, NAFSMA, USACE Action….Future –Study & Analysis? –Committee? –Recommendations?
