REQUESTER: In compliance with 33 USC 408 (Section 14 of the Rivers and Harbors Act of 1899; hereinafter Section 408), Calhoun-Burns and Associates on behalf of Des Moines County, Iowa, has requested permission to modify the Two Rivers LL&D Middle and Upper Levees, an existing federally-authorized flood risk management project in Des Moines County, Iowa.
LOCATION: The proposed project involves the Two Rivers L&DD Middle and Upper Levees and is located where the 40th Avenue bridge crosses the Hawkeye-Dolbee Diversion Channel in Des Moines County, Iowa.
LOCATION MAP(S)/DRAWING(S): See Figures 1 and 2.
REQUESTER’S PROPOSED ACTION: The proposed project would include building a new 324 feet by 30 feet pre-tensioned, pre-stressed, concrete beam bridge as a replacement to the current 40th Avenue bridge over the Hawkeye-Dolbee Diversion Channel. The current bridge has extensively deteriorated and reached its rehabilitation lifespan. Benefit of the alteration would provide wider lanes for the traveling public, increased load-carrying capability, and incorporation of modern safety features. The proposed replacement will modify the Two Rivers L&DD Middle and Upper Levees. To ensure protection of the public investment in the project, some revetments will be in place.
This is a federally-funded project through the Federal Highway Administration (FHWA).
