Anoka County 2019 Multi-Jurisdictional All Hazards Mitigation Plan 97 Since 1961, 444 severe thunderstorms, hail, lightning, and wind have impacted Anoka County and its jurisdictions resulting in 3 fatalities and 195 injuries. The storms have also caused structure damage and content loss. The city of Anoka experienced an unusually severe storm in September of 2005. There was damage to homes, trees, streets were closed due to flooding and septic, and drain field failures occurred. Extensive debris removal was required. Blaine experienced severe thunderstorms in 1987, 1991 and 2002. In 1987 the Police Department fleet of squad cars sustained $74,000 in damage from large hail. Downed trees and roof damage were the major impact of these storms. Damage amounts are unknown but estimated in the $500,000 range per major storm event. The likelihood of occurrence of these storms is high due to Blaine’s climate and geographic location. Thunderstorms are a frequent occurrence for the City of Blaine. With Blaine’s rate of growth and construction practices what they are, loss from future severe thunder storms would be more significant than what has been seen historically. City of Nowthen, Centerville, Circle Pines, Columbia Heights, Ham Lake, Oak Grove, Spring Lake Park, St. Francis and Hilltop experienced severe Thunderstorms, hail, winds, lightening in 2001, 2004 and twice in 2005. In all cases power outages occurred resulting from downed power lines. Hundreds of trees have been destroyed by these storms. It is expected that the frequency of these storms will continue to be moderate and the impact moderate. In the 2005 severe weather event, Coon Rapids experienced hundreds of trees uprooted, power outages due to downed lines; property damage including but not limited to debris damage to private property; some roofs taken off, streets blocked by debris and downed trees; urban flooding due to heavy rainfall and catch basins clogged with debris; hail damage. In 1996, Fridley encountered over 2 Million dollars in damage from a severe storm. In 1998 another 2.2 million in damage and over 1.5 million in damage from the September 2005 storm. Ham Lake, on July 1, 1997, was impacted by a severe storm. The Fire Department responded to many calls, municipal employees worked overtime, pumping was required to stabilize a pond in one neighborhood and prevent loss of property/lives, the fire station required roof repair, and a city owned billboard required repair. Overall the frequency of future occurrences will continue and are considered moderate. The impact of these severe storms is moderate to high and as construction and population continue to increase the impact is expected to increase to high. A detailed list of severe storms is provided in Appendix A. (2011 heavy rainfall event) In June 2017, a severe storm passed over the City of Coon Rapids, Circle Pines, and Blaine causing severe damage to buildings and structures. Streets in many communities were flooded with rainwater. In several places, mounds of hail could be seen floating on the floodwaters like small icebergs. In Coon Rapids, so much hail fell that streets had to be plowed. The estimated loss is in the range of 1 Billion dollars across Anoka County.
