A thriving rain garden installed in Columbia Heights in 2018. With proper maintenance, native species planted in rain garden will fill the entire space within ~3 years.


Four rain gardens are being 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 will provide 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. 

The largest of the four Anoka rain gardens – a double inlet project which will treat stormwater from two adjacent roadways.

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