Downtown Stormwater Improvements

Project Summary

St Joseph Creek is conveyed through downtown Downers Grove in a large diameter concrete pipe nearly a mile long. The storm sewer was installed in the 1960's. Maintenance is required to ensure the pipe will continue to convey the creek flow and stormwater runoff safely. In this multi-year project we will clean, repair, and line the pipe.

LATEST UPDATE

May 8, 2026

1. Work continues to line the first section of the pipe. The large amount of rainfall this spring has made progress slower than anticipated.
2. Work also continues to clean and televise the second section of pipe. This work is expected to be complete within the next week. Repairs and lining of that section of pipe will follow.
3. The Washington entrance to the parking deck is expected to remain closed until Grove Fest.
