28 Appendix B: Calculated Priority Risk Index The Calculated Priority Risk Index in Figure B1 is informed by FEMA’s guidelines for comparing hazards, as described in the Local Mitigation Planning Handbook (2013). The focus here, based on available data, is on the types of assets exposed to a given hazard and the magnitude of the impact. The rankings for types of assets exposed to a given hazard are: low – only assets that will not compound hazard effects or that are replaceable are subject to the hazard, medium – important assets or those that could lead to secondary hazards if damaged are subject to the hazard, and high – critical assets that could lead to immediate secondary hazards if damaged are subject to the hazard. For magnitude, the rankings are: low – no critical assets are affected, medium – some critical assets and/or a large number of important assets are affected, and high – several critical assets are affected. FEMA defines critical facilities as “all public and private facilities deemed by a community to be essential for the delivery of vital services, protection of special populations, and the provision of other services of importance for that community.”52 This includes emergency response facilities, healthcare facilities, transportation infrastructure, schools, emergency shelters, utilities, communications facilities and other assets important to maintaining the health and safety of city residents.
