Clark Dietz is proud to be ranked No. 60 on Engineering News-Record’s (ENR’s) Top Midwest Design Firms list. This annual ranking recognizes the leading design firms based on revenue for work performed in throughout the Midwest. We’re honored to be included among the most impactful firms shaping the built environment across the region.

With offices across Wisconsin, Michigan, Indiana, Illinois, and Kentucky, Clark Dietz is rooted in the Midwest and committed to delivering high-impact infrastructure solutions in transportation, traffic, bridges and structures, water, wastewater, stormwater, civil and environmental engineering, and mechanical and electrical design.

Our 2024 regional revenue totaled $43.57 million, reflecting our steady growth and continued investment in infrastructure that serves our communities. One of our largest projects to break ground was the Garden Hills Drainage Improvements in Champaign, Illinois—a vital project addressing chronic flooding and safety concerns in a historically underserved neighborhood.

Our team’s work has also been recognized across the region:

  • In Wisconsin, the 60th Street Corridor Reconstruction was named a State Finalist in the 2025 ACEC Wisconsin Engineering Excellence Awards, recognizing its innovative design and positive community impact.

  • In Illinois, Clark Dietz, in collaboration with the Village of Savoy and the City of Champaign, received the 2024 Outstanding Civil Engineering Achievement Award from the ASCE Central Illinois Section for the Planning and Funding stage of the Curtis Road Grade Separation and Complete Streets Project—a transformative, decades-in-the-making regional effort.

  • In Indiana, the Kokomo Stellantis EV Battery Plant Stormwater and Roadway Improvement project was honored with an ACEC IN Honor Award and went on to win an ACEC National Recognition Award, recognizing its excellence in engineering innovation and collaboration on a nationally significant infrastructure effort.

These recognitions underscore our presence and purpose across the Midwest: designing smarter infrastructure that serves and strengthens communities.

We’re proud to be part of the Midwest’s future—and we’re just getting started.
