The Loss Avoidance Assessment is one method to validate, streamline, and improve the allocaon of public resources to hazard migaon investments in Florida. Loss Avoidance Assessments (LAAs) are invaluable tools in execung the ‘evaluaon of effecveness’ phase of the hazard migaon process. LAAs can successfully demonstrate the effecveness of migaon processes by quanfying the damages in a community before and aer migaon measures have been made. By quanfying losses avoided through the implementaon of migaon projects, LAAs provide figures that substanate the significant returns on investment (ROIs) that these projects produce. Consequently, these evaluaons provide findings that shape and enhance future decision-making in hazard migaon planning. This, in turn, helps bolster public resource allocaon for migaon and promotes the broad implementaon of quanfiable best pracces for risk migaon and loss reducon across the state. FDEM conducts LAAs aer major presidenally declared disasters to quanfy the economic losses avoided in the area of impact as a result of pre-disaster migaon acvies. This ongoing assessment of both prevented damage and migaon benefits helps illustrate the overall return on public investment, inform programmac improvements, and jusfy the connued funding of migaon projects in areas affected by natural hazards. “This document provides a brief overview of the impacts of Hurricane Michael in Bay County, and the final results of FDEM’s Loss Avoidance Assessment for DR-4399 for migaon measures implemented at the me of the disaster (October 11, 2018).“ Hurricane Michael in Bay County Hurricane Michael made landfall in Bay County as a Category 5 hurricane. Essenally all coastal structures in Mexico Beach were destroyed by wind gusts as strong as 155 mph. Storm surge inundaon as high as 9-14 feet caused further structural damage. Significant damage occurred to buildings, mobile homes, infrastructure, railcars, and derelict vessels. Porons of Highway 98 were washed out by storm surge and waves. Thousands of acres of forest were also catastrophically and severely damaged. Although inland flooding was generally limited, SR-20 bridge was inundated by Econfina Creek when floodwaters reached 26.17 feet NAVD88. The highest mean rainfall in Bay County for October 11, 2018 was 7.91 inches within the City of Lynn Haven. Note that this assessment only considers migaon projects for which FDEM was a partner in funding; this includes projects funded through FEMA’s Hazard Migaon Grant Program (HMGP), Non-Disaster grant programs, and other state programs such as the Residenal Construcon Migaon Program (RCMP) and the Hurricane Loss Migaon Program (HLMP). The purpose of the Bay County report is to connuously collect local official’s feedback on the disaster impacts. It can also be ulized as an internal mechanism to promote connued migaon efforts. For more informaon on the loss avoidance assessment process, methodology, data sources, and study limitaons, please refer to the full DR-4399 Loss Avoidance Assessment. Approach Analysts used Hurricane Michael event data to evaluate the area of impact, and esmate losses avoided and ROI for each migaon project within the area of impact. Hurricane Michael impacted Bay County through significant wind speeds and storm surge. The Hurricane Michael event data database consisted of a number of resources, including data from the Naonal Oceanic and Atmospheric Associaon (NOAA), the Naonal Weather Service (NWS), United States Geological Survey (USGS), and FEMA resources. “Analysts overlay migaon project and disaster event data in GIS to determine which projects lie within the DR-4399 area of impact for inclusion in the LAA. Analysts esmate impacts to the projects using event data, then confirm them through phone calls, emails, and meengs with local representaves familiar with idenfied migaon measures. Florida’s Loss Avoidance Calculators quanfy the effecveness of the impacted migaon projects. Analysts adjust the results to reflect the impacts conveyed by local representaves, as appropriate.” Results Final results were analyzed for 11 projects within Hurricane Michael’s area of impact for wind, precipitaon, and storm surge in Bay County Of the 11 projects analyzed, seven of them were wind retrofit projects, three of them were acquision projects, and one of the projects was an elevaon project. However, only the seven wind retrofit projects returned results. These projects had a cumulave cost of roughly $2,766,685 to implement and assisted in avoiding $1,147,875 in losses in Hurricane Michael—a aggregate return on investment (ROI) of 41 percent. Overall, wind retrofit projects had the highest average ROI, with the average ROI for each individual wind project being 105%.

Hurricane Michael in Calhoun County Calhoun County was one of the Florida Panhandle Counes that was directly impacted by Hurricane Michael. Downed power lines occurred throughout the area, where approximately 100 percent of the County lost power. Only a few homes were impacted by moderate flooding, although the second highest rainfall amount was observed in Calhoun County at 6.66 inches. As well, hundreds of thousands of acres of forest were catastrophically (95% loss) or severely (75% loss) damaged. Note that this assessment only considers migaon projects for which FDEM was a partner in funding; this includes projects funded through FEMA’s Hazard Migaon Grant Program (HMGP), Non-Disaster grant programs, and other state programs such as the Residenal Construcon Migaon Program (RCMP) and the Hurricane Loss Migaon Program (HLMP).
