The erosion is seriously affecting the streambank in the area of th effluent discharge outfall. The proposal for emergency streambank protection presented in this report recommends channel relocation along with placement of riprap along approximately 230 linear feet of the left descending bank and along 60 linear feet of the right descending bank of Sangamon Creek, including portions of the right descending bank of the Sangamon River. The total estimated cost for the project is $57,100, with a benefit-to-cost ratio of 2.5. The project satisfies the criteria for Federal participation and is recommended for construction.
