Construction Complete for Anoka Rain Gardens

Four rain gardens were installed in a northern Anoka neighborhood as part of the City's 2022 Street Surface Improvement Project. Collectively, these gardens will capture nearly 10 acres' worth of stormwater runoff (over 700,000 gallons annually) which would otherwise drain untreated to the Rum River. Through this, sediment loading to the river will be reduced by 969 pounds/year, and total phosphorus loading will be reduced by 3 pounds/year.

Each garden provides additional ecological benefits through the planting of a diverse range of native species, creating several hundred square feet of rich pollinator habitat within the Rum River corridor. Species planted included butterfly weed, cardinal flower, swamp milkweed, red-osier dogwood, dwarf bush honeysuckle, and several others. 

Funding for project design was provided by the Metropolitan Conservation Districts Engineering and Technical Assistance Program, and funding for construction was provided by the City of Anoka and State Watershed-based Implementation Funding.
