RFP: Feasibility Study Consultant for Stormwater Wetland Treatment Project

Delta Institute Overview

Delta Institute is a 501(c)(3) organization. Delta Institute collaborates with communities to solve complex environmental challenges throughout the Midwest. We address Midwestern environmental, economic, and climate challenges today so that our home and region are more resilient, equitable, and innovative tomorrow. Delta is working with our long-term partner, the Illinois International Port District, to assess and evaluate the placement and creation of new stormwater treatment wetland locations that will capture stormwater and remediate existing contamination on IIPD land–keeping pollutants from entering the Calumet River and traveling through dozens of downstream communities.


Illinois International Port District (IIPD) Overview

The IIPD’s Iroquois Landing facility situated at the southwest corner of Lake Michigan and the entrance of the Calumet River, sits on 190 acres and receives international ship traffic through the St. Lawrence Seaway. The IIPD, in partnership with the Chicago Metropolitan Agency for Planning (CMAP), conducted a study to develop a port master plan. The plan’s purpose is to give the IIPD a clear vision of how the port should develop through 2050 with input from the communities and stakeholders. The plan vision will encompass IIPD’s property: Iroquois Landing and Lake Calumet by identifying strategies to better utilize existing facilities and position the port to realize its full economic potential, while also providing workforce, community, recreational, and environmental benefits. These strategies will consider the port’s position within local, regional, state, national, and international contexts. See the map of the IIPD below.


Project Overview

Delta Institute is undertaking a highly collaborative project with the IIPD, Chicago Metropolitan Agency for Planning (CMAP), and community stakeholders to improve water quality along the Calumet River by restoring portions of IIPD property at Lake Calumet. This is a major priority in the IIPD Master Plan released in 2022. Delta has completed a site prioritization process to identify potential locations for wetlands or other green infrastructure. Delta is also supporting and coordinating with the IIPD Community Advisory Team (CAT), a group of residents from communities neighboring IIPD property that provide input on future and ongoing IIPD projects. Additionally, Delta has finished preliminary modeling of treatment wetland impacts. The site prioritization results, expected stormwater impact metrics, and CAT input will inform a comprehensive feasibility study. The study will help determine project cost, viability, design, and impact for selected sites and provide recommendations for implementation. Delta’s efforts directly align with the IIPD’s planning, which seeks to modernize for beneficial economic, social, and environmental outcomes.
