Hundreds of Project Opportunities Near the Rum & Mississippi Rivers

Stormwater runoff from human-modified landscapes is a source of excess water and pollutants that can significantly impact rivers, lakes, and wetlands on the receiving end. However, not all drainage areas are created equally; rural landscapes with abundant agriculture and artificial drainage features, or urban areas with infrastructure predating stormwater treatment regulations, are often the most impactful. Areas draining to a priority waterbody are targeted for Subwatershed and Stormwater Retrofit Analyses (SRAs and SWAs). In these analyses, we study how runoff is moving through the landscape, strategically place various Best Management Practices (BMP's), and estimate their anticipated water quality benefits and installation costs. These findings are then summarized into a report which can be referenced by ACD staff and local natural resource managers to pursue the most cost effective projects. 

Ongoing SRAs and SWAs. Altogether, ~800 (urban) acres draining to the Mississippi River and over 30,000 (primarily rural) acres draining to the Rum River have been analyzed for BMP opportunities.

ACD has completed several SRA/ SWA reports, but current efforts are focused on areas draining to the Rum and Mississippi rivers. Projects sited in these areas include rain gardens, subsurface treatment structures, enhanced street sweeping, wetland restorations, soil health practices (cover crops, no- till farming, etc.), and targeted agricultural practices (grassed waterways, riparian buffer enhancements, control basins, etc.). Altogether, approximately 150 urban BMPs and over 300 rural BMPs have been sited, and their associated SRA/ SWA reports will be released in the coming months.

Lower Rice Creek Stormwater Retrofit Analysis

The Rice Creek Watershed District (RCWD) contracted with ACD to complete a stormwater retrofit analysis for the purpose of identifying and ranking water quality improvement projects throughout select drainage areas to Lower Rice Creek in Anoka County. The report is in final review by the Technical Advisory Committee, and the final report will be completed by July 1st.

A total of 145 projects were identified throughout the 1,115-acre study area and generally consisted of rain gardens, underground sediment collection chambers, and stormwater pond installations or modifications. Potential projects were ranked in order of cost-effectiveness. The report provides a tool for natural resource managers when considering the implementation of projects to improve water quality in Lower Rice Creek.

The project is funded by RCWD and a Metropolitan Conservation Districts Clean Water Fund Accelerated Implementation grant.
