Location
Southeast Des Moines, Southwest Pleasant Hill, Iowa
Description
Red Rock Remedial Works protects Southeast Des Moines/Southwest Pleasant Hill (SEDM/SWPH) from the backup effect of the Red Rock reservoir during large magnitude floods. The remedial works also provides a flood protection benefit for the cities from the Des Moines River. During the Flood of 2008, several deficiencies were discovered with these structures.
The SEDM/SWPH levee is physically and hydraulically connected to the Des Moines I system. The levee system protects much of the city's critical infrastructure, including City Hall; Police Station; regional sewage treatment facility for cities within the Des Moines area; the Greater Des Moines Generating Station; a regional Verizon Communications hub; the Magellan Pipeline petroleum storage facility, which is the largest in Iowa and considered by the Department of Homeland Security as a strategic point of business.
The value of the protected area could exceed $1 billion. Flooding of these areas would result in extensive inundation of neighborhoods and commercial/industrial areas that could cause serious contamination of Red Rock Reservoir. Downstream from the Remedial Works, the Des Moines River is a primary source of drinking water for the city of Ottumwa. Approximately 600,000 people would be impacted by the flooding throughout the Des Moines levee system. The economic; disrupted energy production and distribution; and environmental disaster would be significant for this area.
Status
Project is in operation. WRDA 2022 authorized Federal easement conveyance actions to address legacy real estate issues associated with the SEDM Levee System near the existing Wastewater Reclamation Authority (WRA) treatment facility. The City of Des Moines and the District are coordinating on the next steps to advance the authorized conveyances. Current actions include developing the required agreement between the City and the Corps, advancing legal descriptions and new surveys, and negotiating administrative fee costs.
