Computations of Economic Impacts of Flood Risk

One of the most prominent USACE's Civil Works programs is the Flood Risk Management (FRM) program. The types of infrastructure that fall under this category of investment include levees, storage reservoirs, and other types of floodplain management structural measures. Some of these projects may have multiple purposes. For example, reservoirs that help prevent flooding may also provide storage for water supply and produce hydropower. USACE annually tracks FRM programmatic benefits in its Annual Flood Damage Report to Congress. Each Annual Flood Damage Report includes assessments of flood damages, acres inundated, property damages, loss of life, and damages prevented by previously completed flood risk management projects (not including reductions in damages from coastal storm surge impacts). The estimates of FRM benefits shown are taken from the data supporting the Annual Flood Damage Report Fiscal Year 2014 (available at [Corps Only]). The FRM benefits are an estimate of the monetary value of damages that floods would have caused in the absence of USACE investments that were put in place to prevent those damages. The FY 2014 FRM benefits are estimated to be approximately $14.83 billion. It should be noted that each FRM benefit estimate is based on the weather conditions for the given year (years with many storms likely show greater benefits than non-stormy years since damages prevented are measured as benefits). The 10-year average damage reduction (FY 2005-2014) is approximately $47.74 billion; so, FY 2014 damages prevented are roughly 31% of the 10-year average.
