The U.S. Army Corps of Engineers Kansas City District has studied flood risk management and reliability improvements for the seven levee units in the Kansas City metropolitan area and is seeking review and public comment on the information presented within the Draft Final Feasibility Report (DFFR).
The study was conducted at the request and with cooperation of the sponsors of the seven levee units under the authority of Section 216 of the 1970 Flood Control Act. Any comments received will be considered by the Corps of Engineers to determine whether to modify the recommendations within the report.
The purpose of the overall study of the seven levee units was to determine whether one or more plans for improvements to the existing levee system to reduce flood risk and improve levee reliability is technically viable, economically feasible, and environmentally acceptable, or if no action is warranted. Failure of any part of the existing flood risk management system during a major flood would have significant adverse impacts on the human environment including property damage and potential loss of human life.
The recommendations for the reliability improvements in the Armourdale and Central Industrial District (CID) units are addressed and available for review in the DFFR, which presents the completed feasibility analysis of alternatives for the Armourdale and CID levee units.
Proposed alternatives identified to improve flood risk management system reliability include, but are not limited to earthen levee raise, pump station modifications, floodwall replacement, stoplog and sandbag closures, pressure relief wells, floodwall modification using buttresses, and the no action alternative. DFFR analysis concluded that the nominal 500-year+3ft projected water surface elevation levee raise and underseepage improvements is the preferred alternative for both the Armourdale and CID units.
