Abstract: The Cedar River, Cedar Rapids, Iowa, Flood Risk Management Project Feasibility Study Report with Integrated Environmental Assessment (Study) documents the plan formulation studies conducted by the US Army Corps of Engineers, Rock Island District (District) in close cooperation with the City of Cedar Rapids, Iowa (City). The City is the non-Federal Sponsor for this Study. The purpose of the Study is to identify, formulate and evaluate cost effective, environmentally-sensitive, and technically feasible flood risk management Federal alternatives for the City. The 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. Problems with the aquatic ecosystem within the Study area include degradation due to urban development. In addition, study information indicates Cedar Lake sediments may contain environmental contaminants. During infrequent high flow events, the City’s Water Pollution Control Facilities are inundated and raw sewage must be discharged directly to the river. However, development of measures to address these problems is severely constrained by the lack of suitable and effective options in the urban corridor. 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.
