Groveland Levee Flood Risk Management Project

February 2024 Update

At the Village Board meeting on February 15, 2024, Village Engineer Tracy Wais of Christopher B. Burke Engineering, Ltd. provided the Village Board an update regarding the Groveland Avenue Levee/Floodwall Project.

At the March 2, 2023 Village Board meeting, the United States Army Corps of Engineers (USACE) presented a status report on the project. This update included the background details, the proposed alignment of the floodwall, project costs, funding update and a proposed schedule. The design had been updated to include two pump stations. The overall construction costs were stated to be $7.2 million with estimated project completion in 2028.

On October 2, 2023, the Village received a letter from the USACE regarding fees accumulated for the project thus far. The costs for the project are split 65% by the federal government and 35% by non-federal government sources. According to the letter, there is currently a non-federal balance of $79,868.37. The Village is working with local agencies, including the Metropolitan Water Reclamation District (MWRD), to ensure a proper payment allocation.

On October 18, 2023, the Village held a meeting with the USACE and MWRD to discuss updated construction costs. With the scope changes and material cost increases the USACE explained that the overall project cost has increased to $17.9 million. This amount is substantially higher than the original costs. MWRD and the Village requested alternative solutions from the USACE.

On February 9, 2024 a meeting was held with the USACE to discuss alternative design options which provide lower construction costs. Three alternatives were provided:

Construction Cost $8.3 Million

  • Eliminates two pump stations and underground retention
  • Includes new floodwall and increased elevation of floodwall
  • Adds five outlets to provide relief through floodwall

Construction Cost $11.4 Million

  • Removes North Pump Station but maintains South Pump Station
  • Removes underground retention
  • Includes new floodwall and increased elevation of floodwall

Construction Cost $10.3 million

  • Same as $11.4 million option but with a smaller capacity pump station, which reduces ability for future connections to storm sewers

The Village and MWRD will continue to discuss these alternatives with the USACE. Additionally, staff will be reaching out to MWRD leadership regarding funding the increased costs of the project.

November 18, 2022 Update

The Village Board has received a revised schedule of the Groveland Floodwall project. The Village Board and Commissions welcome feedback on the floodwall project.

  1. Finalize Alignment - Spring 2023
  2. Final Engineering and Design - Fall 2023/Spring 2024
  3. Real Estate Acquisition - 18-24 months
  4. Award Construction Contract - Fall 2025
  5. Construction Begins - Late Winter 2025/Early Spring 2026
  6. Construction Ends - Summer 2028

There is currently a berm along Groveland Avenue; however, flooding occurs around the berm due to elevations in the area. The scope of the proposed Groveland Avenue Levee Flood Risk Management Project includes extending the line of protection. This will significantly reduce flooding in the area but will not remove adjacent properties from the floodplain.

This project was presented to Village staff in 2015; however, at that time it was noted that the Village did not have the resources to fund the non-federal portion of the project. Discussions resumed in 2017 after the Metropolitan Water Reclamation District of Greater Chicago (MWRD) notified the Village that they would fund the non-federal portion of the costs of the project. The modeling that was completed by both the US Army Corps of Engineers (USACE) and Illinois Department of Natural Resources (IDNR) was reviewed by the Village Engineers at Burke Engineering. 

The US Army Corps of Engineers outlined the Groveland Avenue Levee Flood Risk Management Project and the benefits to residents in the impacted area at the Village Board Meeting on Thursday, April 5, 2018. Representatives from Burke Engineering were in attendance at the meeting to answer questions from residents and the Village Board.  Representatives from MWRD and IDNR were unable to attend the meeting, however, they reviewed various modeling, participated in discussions and are supportive of the project. Below is an outline of the project costs and a tentative timeline:
