<br /> Anoka County 2019 <br />Multi-Jurisdictional <br />All Hazards Mitigation Plan <br /> <br /> 108 <br />Geospacial Analysis software from ESRI that Anoka County Emergency Management would <br />like to purchase in the future to provide for additional features in HAZUS-MR. <br /> <br />Qualitative Methodology relies less on technology, and more on historical and anecdotal data, <br />community input, and professional judgment <br />regarding expected hazard impacts. The qualitative <br />assessment is built around varying degrees and <br />weights of risk values as assigned by the consensus <br />of Anoka County’s Hazard Mitigation Steering <br />Committee. <br /> <br />The vulnerability assessment for Anoka County uses <br />a scoring system based on the adjacent table. <br /> <br />Risk Analysis In 2011 Anoka County completed a <br />risk and hazard assessment using Digital Sandbox. <br />The results are being used to assess and review the <br />natural and manmade risks to Anoka County. On an <br />annual basis updates are conducted using the <br />Department of Homeland Security THIRA (Threat <br />Hazard Identification Risk Assessment) <br />methodology. <br /> <br /> <br />111B4.4.1.1 Countywide Hazard Vulnerability <br />After analyzing and evaluating all available data, the <br />Emergency Management Group developed the <br />hazard history vulnerability assessment. The table <br />below lists the hazards identified by the group as <br />hazards that have impacted Anoka County and its <br />municipalities in the past and the potential hazards <br />that could impact the county and its municipalities in <br />the future. The committee then used the risk table <br />developed previously to determine the county’s <br />degree of vulnerability to each hazard. <br /> <br />When historical information for all selected hazards <br />is evaluated and scored, flooding is the number one <br />hazard that has impacted Anoka County. It was <br />recognized that the availability and quantity of data varied significantly between hazards and <br />thus impacted evaluations. The committee believed that had economic data been accurately <br />recorded, urban fires and severe weather dollars could easily have been up to 5-10 times <br />greater. <br /> <br />Below are tables that summarize the hazards that the Emergency Management Group identified <br />as the potential hazards that could affect the communities in the county. <br /> <br />In 2011 Anoka County completed a risk and capability assessment though Digital sandbox and <br />is participating in additional regional Threat and Risk Assessment though the Twin Cities Urban <br />Area Security Initiative (UASI). The results of these studies will be used to increase the <br />readiness of Anoka County and it’s jurisdictions to respond to large-scale events and disasters <br />HAZARD RATING <br />No Fatalities/Injuries 0 <br />Less than 3 injuries 1 <br />Less than 5 fatalities/10 injuries 2 <br />Less than 15 fatalities/50 injuries 3 <br />Less than 25 fatalities/100 injuries 4 <br />More than 26 fatalities/injuries 5 <br />No Economic Damage or Cost 0 <br />Less than 500,000 damage cost 1 <br />Less than 2,000,000 damage cost 2 <br />Less than 5,000,000 damage cost 3 <br />Less than 10,000,000 damage cost 4 <br />More than 10,000,000 damage cost 5 <br />Extent area minimal/no evacuation 0 <br />Extent area local/minimal evacuation 1 <br />Extent area local/some evacuation 2 <br />Extent area 1 mi./some evacuation 3 <br />Extent area 3 mi./major evacuation 4 <br />Extent area >3 mile/evacuation 5 <br />Probability once in 100+ years 0 <br />Probability once in 50 years 1 <br />Probability once in 10 years 2 <br />Probability once in every 5 years 3 <br />Probability once in every 1 year 4 <br />Probability more than once in 1 year 5 <br />No repetitive loss 0 <br />One repetitive loss 1 <br />Three repetitive losses 2 <br />Five repetitive losses 3 <br />Ten repetitive losses 4 <br />More than ten repetitive losses 5
