Keokuk To Improve Flood-Wall
Keokuk, IA – A 2,200' long earthen wall protects Keokuk's wastewater treatment plant and Roquette America's riverfront complex from the Mississippi River. The flood-wall was built after the Flood of 1993.
Keokuk Public Works Director Gerald Moughler says the flood wall is very stable. He says it did suffer some erosion, though, during the flood of 2008.
Moughler says the U.S. Army Corps of Engineers is willing to help the city reinforce the structure with 6,000-8,000 tons of large rock.
Rip-rap is currently in place about 20' above the low water mark for the Mississippi River. The new rock will provide another 30' of erosion protection.
Moughler says the project could cost $300,000-$600,000. He says Keokuk would have to come up with $60,000-$120,000, which is not included in the current budget.
Moughler says the U.S Army Corps of Engineers will handle the bid process for the city. He says it could be several months before the rock is installed, which could be in the middle of flood season.
Keokuk is also moving forward with plans to seek bids to "double-chip and seal" riverfront parking lots and a portion of Mississippi Drive. The areas were damaged during the flood of 2008.
