With significant investment being made in mitigation, demonstrating cost-effectiveness is crucial for continued support. Loss Avoidance Studies (LAS) quantify the losses avoided (also known as damage prevented or benefits) due to the implementation of the projects.
Three separate hurricanes affected the same area of Jefferson Parish between 2005- 2021. After Hurricane Katrina in 2005, FEMA mitigation funds for $2.3 million were used to elevate 23 individual homes. After Hurricane Isaac in 2012, FEMA published a loss avoidance study. This original loss avoidance study has been updated after Hurricane Ida in 2021.
This report, Electrical Transmission and Distribution Mitigation: Loss Avoidance Study, assesses the effectiveness of completed electric system mitigation projects in Nebraska and Kansas affected by the ice and wind storms of December 2006 through January 2007.
Southwestern Community College (SWCC) implemented tornado safe room mitigation measures in constructing two student dormitories. These rooms were completed independent of Hazard Mitigation Assistance (HMA) program funding.
On August 25, 2017, the President approved a Major Disaster Declaration for Texas as Hurricane Harvey dropped an unprecedented amount of rain on coastal areas of the State.
This study examines losses avoided in the State of North Carolina as a result of previous hazard mitigation projects. A large number of the projects were property acquisition and demolition in this analysis. The data clearly show that substantially more damage would have occurred if these properties had not been acquired.
