Cedar River, Cedar Rapids, Iowa, Flood Risk Manage ment Project Feasibility Study Report with Integrated Environmental Assessment [open pdf - 41MB]
"[This] Study is authorized by House Resolution adopted April 5, 2006, by the Committee on Transportation and Infrastructure, and Senate Resolution adopted May 23, 2006, by the Committee on Environment and Public Works. Both resolutions requested the review of past pertinent reports to determine whether any modifications to the recommendations are advisable in the interest of flood risk management, ecosystem restoration, recreation, and related purposes along the Cedar River in Cedar Rapids. The primary problem is the risk of inundation and associated flood damages in the City. By Federal standards, the existing levee system within the Study area has an unacceptable risk of failure during flood events due to insufficient design and construction such as steep side slopes, poor levee construction materials, lack of interior drainage system, and an insufficient crown width. […] The primary goal of this specific Study is to identify, formulate, and evaluate Federal alternatives that could reduce the existing and future flood risk and damages to public and private infrastructure and facilities in the City. The ancillary goals of the Study would evaluate feasible recreational and ecosystem restoration opportunities that are compatible with the primary goal."
