On June 29, 2022, the U.S. Army Corps of Engineers, Kansas City District, and the City of Merriam, Kansas, signed a design agreement to begin design on a series of floodwalls and levees to reduce flood risk in the Merriam community.
The project will involve constructing up to 6.5-foot-tall floodwalls and 6-foot-high levees for around 1.5 miles from Shawnee Mission Parkway to Merriam Drive. It will also require modifications to the Merriam Bridge and other utility modifications.
