Out-of-Date Floodplain Information

• Interim Strategy– Expand partnership and dialogue with FEMA on Map Modernization

• Actions Initiated – Corps Map Modernization PDT – Collection of available information on Corps Federal

levees/floodwalls and shared information with FEMA– Levee Certification Technical team

• Long-Term – More closely align FEMA’s NFIP program with Corps FDR and

Inspection programs

Relevant, Ready, Responsive, Reliable 7

Aging Infrastructure

• Interim Strategy– In partnership with FEMA, state and local partners develop a

comprehensive inventory and database of flood damage reduction structures, assess the condition of those structures, and participate in performing NFIP certification of structures when appropriate.

• Actions Initiated – Developed a GIS spatial database that can be used for both FEMA and

USACE purposes– Develop a risk based assessment methodology for levees and perform

prototype assessments – Initiate “I” wall evaluations using IPET results

• Long-Term– FEMA/Corps Report on Levee/Floodwall Risks– Identification of National Infrastructure Needs for Decision-Makers

Federal Flood Damage Reduction Programs are Uncoordinated

• Interim Strategy– Continue and expand partnership and dialogue with FEMA, other Federal

Agencies and NGOs to integrate Flood Damage Reduction Programs

• Short Term Action Plan– Established the Flood Risk Management Initiative, and the Interagency

Flood Risk Management Committee– Maintain and expand Silver Jacket Initiative for coordination within States.– Corps levee certification guidance collaborated with FEMA– Participate in FEMA’s Interagency Levee Policy Committee

• Long Term– FEMA-Corps Team to develop proposals on modifying federal policy to

maximize return on federal funds used for FDR– Fully integrated Federal programs that contribute to flood risk

management

Relevant, Ready, Responsive, Reliable 12

Improving Corps Capabilities

• Interim Strategy– Increase emphasis on Corps technical competency in areas of risk

assessments, project reliability and inspections

• Short Term Action Plan– Establish ICW PDT to develop and implement improvement plan for

inspection programs, and linking ICW efforts to the Corps Inventory and Assessment Program and FEMA’s NFIP

– Development of a Risk Assessment Methodology for levees

• Long Term– PDT’s to

o Develop recommendations for improving risk capabilities and building awareness of risk management techniques

o Improve flood risk technical policy, criteria, evaluation processes

National Vision (Conceptual)

• The United States Flood Damage Reduction Systems Will Be:

— Safe and Reliable— Managed in a Partnership of

Shared Responsibilities— Assessed in a Comprehensive

and Continuing Program— Effectively Communicated to

All Stakeholders, Decision Makers, and Communities
