Cedar River, Cedar Rapids, Iowa
In June 2008, the City of Cedar Rapids (City), Iowa, was devastated by a flood of record proportions. More than 1,300 city blocks of the City were flooded. The floodwaters covered 10 square miles and caused an estimated $2.4 billion in damages.
On April 5, 2006, Congress authorized a feasibility study. The Feasibility Cost Share Agreement was signed on May 30, 2008. The damaged property inventory for this Feasibility Study counted 7,846 properties damaged by the flood. This included 6,865 residential properties, 754 commercial/industrial properties and 227 public properties. The damaged public properties included the City Water Pollution Control Facility, police station, potable water wells, wastewater collection system, City Hall, Linn County Correctional Center, and Linn County Courthouse, along with many other critical infrastructure elements.
The Feasibility Report presented several alternatives as Flood Risk Management strategies of which one was recommended as the National Economic Development (NED) Plan - Alternative 4-C. Alternative 4-C provides protection along the east bank of the Cedar River. It includes earthen levees, floodwalls, and closure structures for a total length of 3.15 miles. This alternative has a benefit to cost ratio (BCR) of 1.2. The City of Cedar Rapids endorsed the implementation of Alternative 4-C as part of a comprehensive FRM plan for protecting both riverbanks.
The Chief's Report was signed on January 27th, 2011 and transmitted to OMB and Congress.
A Design Agreement (DA) was executed on December 21, 2010 beginning pre-construction engineering and design (PED).
The project was authorized for construction in the Water Resources Reform and Development Act (WRRDA) of 2014.
The project was appropriated funding for construction in the Bi-Partisan Budget Act of 2018 (PL 115-123), also known as Long-term Disaster Recovery Supplemental Funding.
The Water Resources Development Act of 2022 included language authorizing a modified feasibility report to evaluate federal interest in all areas covered by City’s Master Plan.
The city of Cedar Rapids and the USACE Rock Island District executed a Design Agreement Amendment to allow the provision of accelerated non-federal funding to further the PED phase. The City sent the USACE their entire proportionate share of estimated PED costs ($3.1M cash). The City and USACE have executed a Memorandum of Understanding (MOU) outlining work that City may design and construct as Work-In-Kind which is permitted in the DA.
Project was authorized for construction in the Water Resources Reform and Development Act (WRRDA) of 2014. The project received construction funding on Aug. 1, 2018. This funding is to be used to complete design and construct the entirety of the east side flood protection system.
From 2018 to present, the team advanced design on all elements of the flood risk management system. The first federal construction contract was awarded October 2019 and completed November 2020. Several construction contracts are in active construction status.
