Proactive hazard mitigation planning (HMP) that utilizes vulnerability and resilience assessments, mitigation, and adaptation strategies can aid in the reduction of disaster impacts (Frazier, Thompson, and Dezzani 2014; Frazier, Wood, and Yarnal 2010a; Berke and Godschalk 2009; Burby 2006; Burby et al. 2000). It is not possible to mitigate everywhere within the community when large numbers of societal assets are exposed to a hazard; therefore, targeting mitigation allows agencies with limited resources to mitigate in areas where hazard impacts are highest (Frazier, Thompson, and Dezzani 2014; Frazier et al. 2013a). Understanding sub-county vulnerability is important for HMP, as societal assets and human populations are dispersed unequally across
