Definite Project Report with Environmental Assessment for Section 14 Emergency Streambank Protection, Des Moines River, County Road J-12, Wapello County, Iowa. Revision
Abstract
A summary is given of a study made on providing emergency streambank protection along the right descending bank of the Des Moines River, to curtail erosion which is endangering a portion of County Road J-12 in Wapello County, Iowa. The proposal for emergency streambank protection presented in this report recommends the placement of approximately 5,000 tons of Iowa Class D riprap on a filter fabric blanket, and approximately 1,500 cubic yards of earth fill, along 615 linear feet of the right descending bank of the Des Moines River. The total estimated cost for the project is $ 160,300, with a benefit-to-cost ratio of 2. 6. The project satisfies the criteria for Federal participation and is recommended for construction.
