SECTIONFIVERisk AssessmentDMA 2000 REQUIREMENTS – RISK ASSESSMENT – ASSESSING VULNERABILITYAssessing VulnerabilityRequirement § 201.4(c)(2)(ii): [The State risk assessment shall include an] overview and analysis of the State’svulnerability to the hazards described in this paragraph (c)(2), based on estimates provided in local riskassessments as well as the State risk assessment. The State shall describe vulnerability in terms of the jurisdictionsmost threatened by the identified hazards, and most vulnerable to damage and loss associated with hazard events.State owned critical or operated facilities located in the identified hazard areas shall also be addressed.DMA 2000 REQUIREMENTS – RISK ASSESSMENT – ASSESSING VULNERABILITY BYJURISDICTIONElementA. Does the new or updated plan describe the State’s vulnerability based on estimates provided in local riskassessments as well as the State risk assessment?B. Does the new or updated plan describe the State’s vulnerability in terms of the jurisdictions most threatenedand most vulnerable to damage and loss associated with hazard event(s)?C. Does the updated plan explain the process used to analyze the information from the local risk assessments,as necessary?D. Does the updated plan reflect changes in development for jurisdictions in hazard prone areas?DMA 2000 REQUIREMENTS – RISK ASSESSMENT – ASSESSING VULNERABILITY OF STATEFACILITIESElementA. Does the new or updated plan describe the types of State owned or operated critical facilities located in theidentified hazard areas?Source: FEMA 2008.Due to a combination of a lack of adequate information and the lack of a standard methodologyfor a quantitative vulnerability analysis, vulnerability and potential loss results have not beenprepared for the following hazards: coastal erosion; disease; drought; stormwater flooding; highsurf; lightning; non-seismic ground failure; salt spray; slope failure (mudslide and post firedebris flow); terrorism; and transportation accident (aviation and port). Although vulnerabilityand potential loss results have not been prepared for tropical cyclone, the following keysubhazards caused by tropical cyclone are included: coastal/riverine flooding and severe wind. Inaddition, a quantitative vulnerability analysis has not been prepared for HAZMAT sewagedischarge because the sewage is discharged directly into the ocean and therefore does not affectthe assets and population on land.Section 5.5.2 (Most Significant Hazards Vulnerability Results) describes the quantitativevulnerability analysis of the most significant hazards on Guam. The results of this analysis aresummarized in Tables 5-17, 5-18, and 5-19 based on percentage of population exposed.Section 5.5.3 describes the overall vulnerability analysis results for all hazards that could beanalyzed using a quantitative analysis for land use area, population, EFMUTS and the GBS aresummarized in Tables 5-20 and 5-21 and listed by village in Appendix F (Vulnerability andPotential Loss Results by Village).
