Anoka County MINNESOTA Respectful, Innovative, Fiscally Responsible Anoka County 2019 Multi -Jurisdictional All Hazards Mitigation Plan Geospacial Analysis software from ESRI that Anoka County Emergency Management would like to purchase in the future to provide for additional features in HAZUS-MR. Qualitative Methodology relies less on technology, and more on historical and anecdotal data, community input, and professional judgment regarding expected hazard impacts. The qualitative assessment is built around varying degrees and weights of risk values as assigned by the consensus of Anoka County's Hazard Mitigation Steering Committee. The vulnerability assessment for Anoka County uses a scoring system based on the adjacent table. Risk Analysis In 2011 Anoka County completed a risk and hazard assessment using Digital Sandbox. The results are being used to assess and review the natural and manmade risks to Anoka County. On an annual basis updates are conducted using the Department of Homeland Security THIRA (Threat Hazard Identification Risk Assessment) methodology. 4.4.1.1 Countywide Hazard Vulnerability After analyzing and evaluating all available data, the Emergency Management Group developed the hazard history vulnerability assessment. The table below lists the hazards identified by the group as hazards that have impacted Anoka County and its municipalities in the past and the potential hazards that could impact the county and its municipalities in the future. The committee then used the risk table developed previously to determine the county's degree of vulnerability to each hazard. When historical information for all selected hazards is evaluated and scored, flooding is the number one hazard that has impacted Anoka County. It was recognized that the availability and quantity of data varied significantly between hazards and thus impacted evaluations. The committee believed that had economic data been accurately recorded, urban fires and severe weather dollars could easily have been up to 5-10 times greater. HAZARD RATING No Fatalities/Injuries 0 Less than 3 injuries 1 Less than 5 fatalities/10 injuries 2 Less than 15 fatalities/50 injuries 3 Less than 25 fatalities/100 injuries 4 More than 26 fatalities/injuries 5 No Economic Damage or Cost 0 Less than 500,000 damage cost 1 Less than 2,000,000 damage cost 2 Less than 5,000,000 damage cost 3 Less than 10,000,000 damage cost 4 More than 10,000,000 damage cost 5 Extent area minimal/no evacuation 0 Extent area local/minimal evacuation 1 Extent area local/some evacuation 2 Extent area 1 mi./some evacuation 3 Extent area 3 mi./major evacuation 4 Extent area >3 mile/evacuation 5 Probability once in 100+ years 0 Probability once in 50 years 1 Probability once in 10 years 2 Probability once in every 5 years 3 Probability once in every 1 year 4 Probability more than once in 1 year 5 No repetitive loss 0 One repetitive loss 1 Three repetitive losses 2 Five repetitive losses 3 Ten repetitive losses 4 More than ten repetitive losses 5 Below are tables that summarize the hazards that the Emergency Management Group identified as the potential hazards that could affect the communities in the county. In 2011 Anoka County completed a risk and capability assessment though Digital sandbox and is participating in additional regional Threat and Risk Assessment though the Twin Cities Urban Area Security Initiative (UASI). The results of these studies will be used to increase the readiness of Anoka County and it's jurisdictions to respond to large-scale events and disasters 108
