History of Flood Risk Management in the Corps (Value to the Nation)
n Since the Flood Control Act of 1917, one of the primary Missions of the USACE is to provide flood risk management: ● During Flood Episodes ● Studies and Implement Flood Risk Reduction Measures
n Flood Control to Flood Damage Reduction to Flood Risk Management
n Corps has reduced flood risk/damage by implementing many structural and nonstructural measures. (B/C = 7.92)
n Procedures and Programs ● meet changing needs of the country ● utilize new science & technology

HEC-FDA Flood Damage Reduction Analysis
n Corps primary planning tool for FRM n HEC-FDA helps the Corps answer the question, "Which
proposed flood risk management plan is the best from an economic standpoint?" ● Evaluate the existing condition ● Analyze alternative damage reduction plans
n Compare plans using Expected Annual Damage (EAD) and damage reduction benefits.
n Software originated in 1992; continuous improvements over the years with Risk Analysis added in 1997 and last certified in 2012.
