Appendix A. County Threats Assessment Sorted by Aggregate Risk

Assessment Criteria

This assessment is based on the four most significant (from the perspective of likelihood of occurrence, impact to the community and requirement for amateur radio resources) disaster threats in Georgia: floods, hurricanes, tornadoes and winter storms. Each threat was assigned a number corresponding to low risk (1), medium risk (2), or high risk (3). The numbers were assigned county-by-county, based on several risk factors for the county with regards to the specific threat:

All counties were first assigned a low risk (1) for each threat.
The GEMA report indicating number of tornado events by county from 1950 - 2000 was used to establish a risk for tornado for each county-the numbers were assigned as follows: counties with 13 to 23 events were assigned a high risk (3); counties with 5 to 12 events were assigned a medium risk (2) and counties with 0 to 4 events were left at a low risk (1).
The risk was increased by .5 for counties that had received a presidential disaster declaration (according to GEMA ) for a tornado from 1990 - 2000
The risk was increased to medium risk (2) for counties that had received a presidential disaster declaration for flood, hurricane or winter storm from 1990 - 2000 were The risk was increased from medium risk (2) to high risk (3) for the 6 coastal counties identified by GEMA as highest risk of storm surge in a hurricane for the two categories, Floods and Flash Floods, and Hurricane.
The risk for all four categories of threat were aggregated and averaged.
The list of counties was then sorted first by aggregated risk, then by the 2001 US Census estimate of county population.
