Anoka County2025 Hazard Mitigation Planz.umn.edu/AnokaHMP buildings, infrastructure, and the environment to the natural hazards listed inTable 4and to assist local governments in development of related local mitigation actions to reduce risk. The following is a compilation of common responses taken directly from jurisdictional representatives as preserved in Appendix C: Question 2 – Local Vulnerabilities. Responses here are edited only for clarity. Anoka County Flooding: Overland flooding is a concern in Anoka County for events with high rainfall amounts over a short time. The prominent soil type in Anoka County is sand which will allow normal amounts of rainwater to percolate through the soil and move through the stormwater drainage systems moving water through the six Watershed Districts in Anoka County. Tornadoes: Although tornadoes have affected Anoka County infrequently in the past, the probability of damage from this hazard in the future is likely. The entire county is at equal risk of future occurrences. While higher population and housing densities in the municipalities set the stage for increased impact, the potential for property damage and loss of life is equally high for the county's unincorporated areas due to the large number of mobile homes throughout the rural areas. City of Andover Flooding: The City of Andover has low-lying properties along the Rum River and near various wetlands which are prone to flooding. All Hazards (Severe Storms): The city has the usual CI/KR protection concerns as most other communities (i.e., vulnerability of overhead power lines). Our City Hall/Community Center/water treatment facilities can be considered the hub of activities/services within our community. The loss of these assets would be unfortunate. City of Anoka Flooding: The City of Anoka has both the Rum River and Mississippi River that have independent flood risks. Along both waterways there are a handful of private properties and public utilities that are affected by localized flooding. The Coon Rapids Dam may cause ice jams during winter and early spring. Flooding: Our city-owned sanitary sewer infrastructure (lift station, manhole, etc.) are located in the floodplain. Severe Storms (Power Outages): The City of Anoka has municipal electric utilities providing services to the cities of Anoka, Champlin, Dayton, and Coon Rapids and Ramsey. The power grid is a combination of overhead and buried transmission lines, including 5 substations. Severe storms have the potential to affect overhead power lines. Section 3 21 Hazards 30
