Flagg Creek Storm Sewer Outfalls


During the fall of 2020 Village staff completed a storm sewer investigation with V3 Companies for the Village’s storm outfalls located within Flagg Creek. The study photographed and reviewed each of the Village’s outfalls that discharge to Flagg Creek from 47th Street down through the Ridgewood subdivision. The Flagg Creek outfall investigation builds upon other storm water studies that the Village has completed in portions of Ridgewood and Springdale. Rehabilitation of various storm outfalls was an improvement identified in the 2016 Ridgewood Infrastructure Study.

2021 Improvement Project

The Village identified three outfalls for rehabilitation in 2021 near Ridge Lane, Oak Lane, and Crest Lane. Construction will occur from the creek, with access for construction equipment coming from Ridgewood Drive. The removal of undesirable trees, invasive brush (i.e. buckthorn) or other landscaping within the public utility easement, Illinois Tollway property and bank of Flagg Creek may be required to complete the repair work. Any removals or damage that occurs on private property will be restored by the Village. The Village will be separately contacting those residents who are adjacent to the storm-sewer outfalls to coordinate construction access through existing public utility easements.
