An elegant solution to mitigate chronic flooding

The City of Chicago was experiencing overbank flooding during periods of high water flow. This meant extensive property damage to areas in and around Albany Park. The City's department of transportation selected us to provide design, project management, sub-consultant management, and construction cost estimates.

Our design services included tunnel and shaft design, GBR development, and preparation of contract documents. Other key elements of the project included participation in meetings with the local stakeholders, permitting, data collection and management, visits to the project site, and review, modification, and application of existing detailed GIS-based H&H models. We also completed studies of the existing storage and drainage conveyance systems.

The result? We developed the detailed design of a 5,807-foot (1,770-metre) stormwater diversion tunnel that would connect the north branch of the Chicago River (NBCR) to the North Shore Channel (NSC). The proposed diversion system will divert stormwater in excess of 24 inches (61 centimetres) from the NBCR to the NSC in order to help mitigate the City of Chicago’s chronic flooding problems in the Albany Park area during extreme rainfall events.
