Title
Storm Water Detention Basin Evaluation - Phase 1 of Master Plan- RFP Engineering Master Agreement
History
Various portions of the stormwater system are aging and developing maintenance and other related issues that will require attention and substantial investment from the Village. On June 21, 2021, the Public Works Department issued a Request for Proposals (RFP) to develop the first phase of the Storm Water Master Plan. This plan will evaluate 178 Village owned stormwater basins, 88 dry basins and 90 wet basins in our stormwater system to identify any deficiencies. The inspection of each detention basin will include structures, shoreline erosion, energy dissipation, settling, water quality, sedimentation, volume/capacity, encroachment, vegetation, wildlife management, and adjacent land uses.
The summary report will detail the condition of each basin, develop short-term and long-term restoration projects, as well as budget figures. It will include photo documentation of notable issues or major concerns that will need to be addressed in a timely manner. The results of the evaluation will be submitted to Public Works for staff to develop a phased plan for future restoration projects.
Future phases of the Master Plan will consist of evaluating the underground storm sewer network, natural wetlands or riparian areas that also store stormwater runoff, creeks and drainage ways.
The RFP was sent out to the seven (7) prequalified consultants from the earlier engineering consultant RFP, and three (3) proposals were received. Engineering Resource Associates of Warrenville, IL submitted a proposal with a not to exceed cost of $184,380.00, Baxter and Woodman of Mokena, IL; $78,258.00, and Christopher B. Burke Engineering, Ltd. of Rosemont. IL; $74,500.00. Public Works will utilize the existing Master Service Agreement for this project.
