Summary General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
The Argentine Unit levee system reduces the occurrence of flooding in Kansas City, Kansas. The levee system includes five and one half miles of earthen levee and a quarter of a mile of concrete floodwall along the Kansas River. The levee was designed and constructed by the U.S. Army Corps of Engineers (USACE) in 1955. After construction the levee was turned over to the local sponsor, the Kaw Valley Drainage District, for operation and maintenance. The USACE raised the levee and floodwall in 1978 and is currently working on another raise.
Performance & Condition General text description of the historical and anticipated performance of the levee, the people and property benefitting from the levee and who may be at risk of flooding, and actions to address areas of concern.
The USACE evaluates risk as a combination of the flood hazard frequency, the anticipated levee performance, and the potential consequences. A screening level risk assessment was completed on this levee in 2017. The screening level risk assessment estimated the likelihood of a Kansas River flood overtopping this levee in any given year at approximately 0.2%, or a one chance in 500. Overtopping was identified as the primary flooding risk, however all levees have the potential to breach prior to water flowing over the top. The USACE anticipates there being sufficient warning time to evacuate the area prior to water reaching the top of this levee. However, levee breaches prior to water reaching the top often have very short warning times. The risk assessment identified some performance concerns prior to water overtopping the levee under large flooding events. With the 2019 Kansas City Levees Project, the USACE is further evaluating these issues and will be constructing improvements as needed, as well as raising the entire project. The levee was loaded to about half its height in 1993 and performed as designed. The area behind the levee includes residential, commercial, and industrial development. The 2017 screening estimated a leveed area daytime population of approximately 10,700 and the property value to be approximately $3.5 Billion. Flooding of the leveed area could lead to flood depths of 6 to 15 feet, which would result in large consequences due to the high population at risk and property values behind the levee.
