Schaumburg Springinsguth

Our project team was selected by the Village of Schaumburg to evaluate conveyance improvements of the Springinsguth River (West Branch DuPage River tributary) at the existing concrete box culvert under Springinsguth Road. This project was initially conceived in the Poplar Creek Watershed Study, which was authored by the Metropolitan Water Reclamation District (MWRD). As part of the study improvement, the Village was also interested in channel improvements both upstream and downstream of the Springinsguth Road to provide compensatory floodplain storage.

‍

The initial study was prepared in 2010 with an updated memorandum dated 2013. Our team studied the original five alternatives along with six new alternatives. Tasks included:

• Obtain and review prior studies, reports, and hydraulic models

• Coordination with Village staff

• Development of project alternatives along with a rank and scoring relative to project objectives

• Concept plans for floodplain storage facilities in Olde Salem and Jaycee Parks

• Update Hydraulic model and evaluate additional alternatives

• Engineer’s Opinion of Probable Cost

• Exhibits indicating proposed flood mitigation alternatives

• Summary Report

The summary recommendations included Springinsguth Road Culvert improvements consisting of twin 11’x7’ reinforced concrete box constructed in the same phase as the Olde Salem Park Storage facility to avoid offsite increases in 100-year flood stages. Additional floodplain storage of approximately 5.5 acre-ft. would compensate for the increased conveyance of the improved Springinsguth Road crossing. The Jay Cee Park storage facility was identified to further reduce 100-year flood stages. A proposed 11.5 acre-ft. facility would reduce 100-yr flood stage an additional 0.07’ at Cornell Lane. This stage also showed benefits to Hanover Park in the form of a 0.17’ decrease in 100-yr flood stage.

Subsequently in 2020, recognizing the potential flood mitigation benefit in both Schaumburg and Hanover Park, the Villages collaborated to design and permit one project to reduce flood stage and stabilize banks of the West Branch DuPage River downstream of the Springinsguth Road culvert. Representing Schaumburg, our team worked with the Hanover Park consultant team to develop a naturalized channel design, construction documents, and permit documents for 3,250 feet of stream that includes channel re-alignment, stabilization, and in-stream riffles. Permits for the project included approvals from USACE, IDNR-OWR, and MWRD.
