Rockford, Illinois is the 5th largest city in the state. It has long sought effective strategies to protect and restore its waterways through stormwater management. A3 Environmental Consultants – known as Olson Ecological Solutions at the time – addressed these concerns head-on with the South Fork Kent Creek Watershed Plan. This EPA-approved plan focused on a small watershed, west of the Rock River, combining technical analysis with community-driven goals. From pollution sources at the watershed headwaters to the lakes within Levings Park, this Watershed Plan ensured that stormwater management improves water quality, habitat, and recreational opportunities for years to come.
Watershed Plan Overview
A3E’s Watershed Plan spanned 2017–2025 and focused on stormwater management and enhancing water quality in the 7,600-acre South Fork Kent Creek watershed. Municipal officials and stakeholders sought a solution to recurring stormwater pollution, sedimentation, and degraded habitats. A3E delivered a comprehensive, EPA-approved watershed-based plan following IEPA Section 319(h) guidelines, integrating community priorities with technical best practices.
The plan included detailed assessments of runoff patterns, pollutant sources, and hydrological impacts. By applying stormwater wetlands, bioswales, and floating treatment wetlands, the Watershed Plan provided functional solutions that reduce nutrient loading and sediment transport. Each feature followed EPA Green Infrastructure Grant Opportunities (GIGO) best practices for stormwater management. Monitoring through sediment sampling and water quality tests ensured data-driven outcomes, validating the project’s success over eight years.
Process and Methodology
The development of this Watershed Plan adhered to EPA guidance for watershed-based planning. Project management included quarterly progress reports to the U.S. EPA and financial reporting to ensure compliance with grant requirements. Techniques were applied strategically to balance hydrologic function, community needs, and ecological restoration.
A3E even got to see some of the watershed plan to execution with stormwater management activities surrounding Levings Lake. On-site interventions included:
- Stormwater wetlands: constructed to filter pollutants and improve lake water quality
- Bioswales: installed along pathways and runoff channels to capture sediments
- Floating treatment wetlands: innovative technology to enhance nutrient uptake in water bodies
Each method incorporated Best Management Practices (BMPs), leveraging cutting-edge stormwater management approaches to achieve tangible environmental benefits.
Business Impact and Value
This multi-year project generated measurable outcomes for Rockford’s municipal officials and the Rockford Park District. Improved water quality increased recreational opportunities, supported healthier fish populations, and created pollinator habitats. Strategic partnerships facilitated community engagement, grant compliance, and long-term stewardship.
By documenting results through sediment sampling, water quality testing, and EPA reporting, the Watershed Plan positioned Rockford for future implementation phases. From 2017–2025, this initiative exemplified a cost-effective, replicable approach to municipal stormwater management, demonstrating clear environmental, social, and regulatory benefits.
Local and Regional Focus
Rockford’s unique watershed conditions, including Levings Lake and South Fork Kent Creek, required site-specific interventions. The plan considered local rainfall patterns, soil types, and topography to design sustainable stormwater solutions. Engagement with municipal officials ensured the plan met regulatory requirements and reflected community priorities.
Regional grant programs like IEPA Section 319(h) and GIGO funding were integral, providing financial and technical support for planning, construction, and monitoring activities. The project became a benchmark for other Northern Illinois municipalities seeking to implement effective watershed-based stormwater management strategies.
Long Term Benefits and Next Steps
A3E’s Watershed Plan demonstrates how municipal officials can leverage science-driven, community-focused stormwater management to achieve long-term water quality improvements. From planning to implementation, every step of the project advanced Rockford’s environmental resilience.
