Today marks a major victory for South Holland as we celebrate the completion of Phase 1 of the Thorn Ditch Flood Mitigation Project at Maicach Park! 💧🌳 I was proud to join MWRD Vice President Theresa Flynn and Commissioner Yumeka Brown for the ribbon-cutting ceremony, alongside Mayor Don De Graff, the Holland Village Board, and project partners.
With heavier rains becoming more frequent, giving stormwater a safe place to go has never been more important for our communities.
After years of planning and collaboration, this $5.8 million first phase upsized aging culverts along Thorn Ditch and created 11.8 acre-feet of stormwater storage—more than 3.8 million gallons—across Maicach Park and Pioneer Park, along with 50 newly planted native trees.
The new system was put to the test during heavy rains this past June, July, and August, holding strong with zero ditch overflow and no street flooding. It’s a great example of how thoughtful, long-term engineering can make a real difference.
This success would not have been possible without the leadership and partnership of Mayor Don De Graff and the Village of South Holland Board, Metropolitan Water Reclamation District of Greater Chicago Board of Commissioners, the MWRD team through the Stormwater Partnership Program, American Rescue Plan Act (ARPA) funding, and Robinson Engineering.
As we look ahead to the $3.37 million Phase 2 culvert replacement planned for 2027, we can all do our part by keeping neighborhood storm drains clear, using rain barrels, and reducing outdoor water runoff.
Investing in stormwater infrastructure today means stronger, more resilient communities tomorrow. 💧
