Water + Stormwater
Market District ISG Project Location: Des Moines, Iowa Project Start Date: 1 April 2020 Project Completion: 1 June 2024
Project Team: Jerremy Foss, PE, CNU-A, Nick Frederiksen, Will Kratt, PE, PTOE, Chris Frederiksen, Jessica Wendinger, Kent Hays, Micky Eberth, PE, Marisa Young , Joe Klinkel, Stephanie Merdan Project Background: The Market District Master Plan aimed to rejuvenate about 30 acres of the East Village of Des Moines by focusing on the importance of water and visualizing it through the use of green infrastructure. ISG has supported and led the plan’s implementation, providing design services at the conceptual, preliminary, final, construction administration, and traffic impact stages. Over 80 bioretention cells, bioswales, and a water quality basin were designed to treat about 20 million gallons of water each year prior to reaching the Des Moines River. The project required coordination amongst a dozen jurisdictional entities and three property owners to meet the expectations and vision of The District Developer, LLC, the City of Des Moines, and MidAmerican Energy. This allowed for an efficient layout of new infrastructure that cohesively connects to the existing systems in place which provided an organized utility design. Impact: The Market District sets a new standard for integrating urban and green infrastructure at scale, serving as a model for future redevelopment efforts. ISG’s district-wide approach replaces fragmented, property-specific stormwater solutions with a holistic system that promotes sustainability, long-term efficiency, and urban transformation. By combining infrastructure with intentional design, the project demonstrates how engineering can enhance urban livability, shifting public perception of its role in community development. The project’s stormwater management system delivers significant social, environmental, and economic benefits. The biocell system, paired with the City’s dual-purpose detention park, mitigates flood risks while creating a public space that promotes outdoor activities and social interaction, fostering a stronger sense of community. Additionally, the project supports environmental remediation efforts at the adjacent Two Rivers Park, contributing to sustainable redevelopment and public health improvements through cleaner water systems and restored natural areas. This project exemplifies how thoughtful engineering can drive urban revitalization and enhance public spaces.
