Z--Two Foot Raise, Phase II, Flood Risk Management Project, Mad Creek, Mississippi River, Muscatine, IA

The Two Foot Raise, Phase II, Flood Risk Management Project is a construction effort located at Mad Creek along the Mississippi River in Muscatine, Iowa. This project focuses on enhancing flood protection through a wide range of civil engineering tasks, including the demolition of existing steel closure structures, concrete floodwalls, and storage buildings, as well as extensive site preparation involving tree removal, clearing, grubbing, and silt removal from the bridge bay. Key technical components of the work include the installation of steel sheet and H-piling, the construction of a compacted clay levee, and the creation of architecturally textured and colored concrete floodwalls with continuous buttress bases. The scope further encompasses the raising of existing gatewells and steel gate apparatuses, the installation of steel swing and roller gates across railroad and pavement areas, and the completion of infrastructure improvements such as concrete and asphalt paving, sidewalks, and necessary traffic control and railroad flagging services.
