• <br />Anoka County Multi- Jurisdictional <br />All Hazards Mitigation Plan <br />4.3.2.2 Civil Disturbance /Strikes/Workplace Violence <br />It was determined by the Anoka County Hazard Mitigation Committee that the occurrence or <br />impact of this hazards was not of sufficient concern to be included in the plan at this time. <br />4.3.2.3 Dam /Levee Failure <br />Dam break floods are usually associated with <br />intense rainfall or flood conditions. The greatest <br />threat is to people and property in areas <br />immediately below the dam. Dam failure may be <br />caused by faulty design or construction, <br />operational inadequacies, or flooding larger than <br />the dam capacity. The degree and extent of <br />damage depends on the size of the dam. <br />Minnesota has more than 1,200 dams, most of <br />them small agricultural dams. There are some <br />large dams within the state. These dams serve to <br />produce electrical power for the state, control flooding, and provide recreational <br />opportunities. <br />Anoka County and its municipalities have not been affected by dam failure. Regulatory <br />measures reduce the probability of a significant future event. Dam failure is not considered as a <br />hazard in this plan. Three of the five dams listed in the National Inventory of Dams for Anoka <br />County are rated as low hazard. The Coon Rapids Dam and Locke Dam are rated as a <br />significant hazard and will be monitored and evaluated for inclusion in a future update of this <br />plan. The dams in Anoka County are identified below. <br />Dam Name <br />River <br />City <br />Impacted <br />NID <br />Height. <br />NID <br />Storage <br />Year <br />Built <br />Drain <br />Area <br />Hazard <br />Rating <br />Owner Name <br />Coon <br />Rapids <br />Mississippi <br />Coon <br />Rapids <br />35 <br />2000 <br />1913 <br />0 <br />S <br />Hennepin <br />County <br />Locke Lake <br />Rice Creek <br />Fridley <br />25 <br />320 <br />1956 <br />200 <br />S <br />City of Fridley <br />Rum River <br />Rum River <br />Anoka <br />28 <br />1000 <br />1853 <br />1590 <br />L <br />City of Anoka <br />Peltier Lake <br />TR -Rice Creek <br />Blaine <br />13 <br />4650 <br />1930 <br />110 <br />L <br />City of St. Paul <br />R.

However it was decided by the <br />Anoka County Mitigation Committee that the mitigation of this hazard was primarily the mission <br />of Federal and State Departments of Transportation. However should a proposed rail <br />transportation system become a reality for Anoka County as part of a Metropolitan rail system, <br />this hazard would be reconsidered for inclusion in a future plan update. <br />
