<br /> Anoka County 2019 <br />Multi-Jurisdictional <br />All Hazards Mitigation Plan <br /> <br /> 100 <br />Ice storms bring the entire affected area to a standstill. Ice accumulation causes trees and utility <br />lines to fall, interrupting telephone service and creating significant power outages. Emergency <br />response time is greatly increased, especially to residents in remote, rural areas. <br /> <br />Freezing rain, probably the most serious of the ice storms, occurs during a precipitation event <br />when warm air aloft exceeds 32° while the surface remains below the freezing point. When <br />precipitation originating as rain or drizzle contacts physical structures on the surface ice forms <br />on all surfaces creating problems for traffic, utility lines and tree limbs. <br /> <br />Since 1966 there have been 79 reported incidences of severe winter weather that has impacted <br />Anoka County and its municipalities. <br /> <br />Recent Winter Storms impacted Anoka County in 1991, 1996 and 2001. The 1991 & 2001 <br />storms were heavy snowfall events, which impacted transportation, commerce and emergency <br />services. Due to climate and geographic location winter storms can be a frequent occurrence for <br />the entire county. With the continued growth rate and construction practices loss impact from <br />future Winter storms would be more significant than what has been seen historically. <br /> <br />On October 31, 1991, county experienced a severe Winter Storm. Streets were closed. Some <br />state highways were closed to vehicular traffic due to snow depth and quantity. There were <br />power outages to many residents and businesses. There was a complete shutdown of <br />businesses and schools. The likelihood of future occurrences is high and the impact may affect <br />travel for multiple days. <br /> <br />During periods of extreme cold, water towers and water lines, particularly in low-income <br />residences with sub-standard insulation, freeze and break, leaving residents without water and <br />creating a burden on the public and private infrastructure. <br /> <br /> <br />The probability of future winter storm events is moderate to high, and the entire county is at <br />equal risk. A detailed list of Winter Weather events is in Appendix A. <br /> <br /> <br />106B4.3.1.6 Wildfires <br />Wildfires are incidents of uncontrolled burning in <br />grasslands, brush, or woodlands. In Minnesota, <br />significant wild-land fires do not occur on an annual <br />basis. However, several hundred lesser events <br />occur annually across the entire state. Seasonal <br />wild fires have been destructive, especially during <br />periods of drought. <br /> <br />The Minnesota Department of Natural Resources <br />(DNR), Division of Forestry has primary <br />responsibility for wild-land fire protection on 22.8 <br />million acres of public and private land. Its total <br />responsibility encompasses 45.5 million acres or 89 percent of the total land base. Wildfires <br />occur throughout Minnesota and according to the Minnesota State Fire Marshal, there are more <br />than 2,000 annual wildfires with an estimated loss of more than $13 million dollars. <br />
