PROJECT DESCRIPTION
The Cleveland Corridor project involved the installation of a new storm sewer with a 72” main line along Cleveland Street and Monroe Street, branching out to the adjacent side streets of Keeney Street, Monroe Street, Oconto Avenue, Octavia Avenue, Odell Avenue and Oketo Avenue. The project consisted of the installation of a relief sewer to capture stormwater runoff and conveying it to a new outfall to the North Branch Chicago River. Construction of the project is partially funded with Clean Water State Revolving Loan Fund (SRF) funding. The State Revolving Fund program is administered by the Illinois Environmental Protection Agency and receives a portion of its money to fund these types of projects from the U. S. Environmental Protection Agency. Completed in 2016, the project reduces surface water flooding in this neighborhood where more than 140 homes have suffered flood damages due to overland flows.
Approximately 11,200 feet of new storm sewer iwas installed. The main line storm sewer will outlet at the North Branch of the Chicago River to the east of Caldwell Avenue. Major construction was completed in November 2016. The completed project cost is approximately $9 million. The project has received $2 million in assistance from the Metropolitan Water Reclamation District of Greater Chicago (MWRD) in addition to utilizing low interest IEPA loans to reduce the project costs.
This project reduces surface water flooding that has led to repeated overland flooding in this area. This project will not solve all flooding problems, but will greatly improve the drainage condition in the area. The new relief sewer provides capacity to convey surface water away from the impacted area to minimize surface water flood damages. The volume of water entering into the combined sewer system will also be reduced, in turn reducing peak flows through these sewers and the risk of basement backups for residences in the project area. This project provides protection to approximately 140 homes. Benefits from the project were modeled using the detailed overland flooding mapping component of the XPSWMM 2D model.
