Background/Discussion
The City sustained damage to the flood risk reduction system during high water events in 2018 and 2019 and submitted for rehabilitation assistance from the USACE.
The scope of this project repairs the following damage:
o Four outfall structures (Missouri River and Mosquito Creek tieback)
o Three areas of levee restoration totaling 0.75 miles (including thickening of section and flood height along Missouri River)
o Seventeen outfall cleanouts of various lengths and locations (Missouri River and Mosquito Creek tieback)
o Mosquito Creek Mouth cleanout
o Four wet side seeding areas with a total length of 8.5 miles (Missouri River and lower portion of Indian Creek tiebacks)
Without this rehabilitation, the integrity of the levee system could be threatened.
The cost of the rehabilitation project will be paid with federal funding through the USACE PL 84-99 program. The City is responsible for providing lands and suitable borrow material for the work. The estimated cost for the material is $71,750.
The project is scheduled to begin in late 2020.
