East Auburn Stormwater Ponds


Project Status: 
Current Status: 

In 2019, we will finalize planting, signage, and complementary best management practices at the two retrofitted stormwater ponds.

About this project: 

Aerial of East Auburn Stormwater PondsThe City of Victoria prides itself on its healthy, vibrant downtown with a variety of small businesses and entertainment venues. The city began a downtown redevelopment planning process in 2015 to set the vision and direction for anticipated new development in its urban core. Early in the process, the city identified a regulatory challenge: the stormwater ponds for downtown would not supply adequate treatment for the anticipated development.

Working in partnership, Minnehaha Creek Watershed District (MCWD)  and the city planned the retrofit of the existing ponds in such a way as to increase the ponds’ stormwater capacity to capture stormwater from 22 acres of land. Doing so allowed additional development in Victoria’s downtown without having to build new stormwater management facilities. The retrofit of the ponds included installing a filtration bench and an iron-enhanced filtration bench to remove dissolved phosphorus (“bench” is a technical term for a type of filter). These benches enhance the treatment capacity of these ponds. The retrofit of the ponds actually allowed the capture and treatment of stormwater from land that would have been exempt from the regulatory stormwater rules, meaning even more stormwater is being filtered before entering East Auburn Lake.

Additionally, the outlet of Church Lake was directed to the stormwater ponds so that additional pollutants would be filtered out of the water before entering East Auburn Lake, which is an impaired lake. By doing this, the City of Victoria went above and beyond the requirements of our rules and provided even more important water quality improvements that will make a difference downstream in Halsted Bay.

The project was supported by funding from the Clean Water, Land, and Legacy Fund. The remaining cost of the retrofit was funded by the City of Victoria.

Six Mile Creek – Halsted Bay Subwatershed Partnership:

This project is a result of the ongoing coordination and communication with partners about plans, priorities, and opportunities for collaboration in the Six Mile Creek – Halsted Bay Subwatershed. This coordination is facilitated by the Six Mile Creek – Halsted Bay Subwatershed Partnership, which we convened in 2015 and includes Carver and Hennepin Counties; Cities of Minnetrista, St. Bonifacius, Victoria, and Waconia; Laketown Township; Carver County Soil and Water Conservation District; and Three Rivers Park District.

We are focusing in the Six Mile Creek – Halsted Bay Subwatershed over the next ten years in an effort to make long-lasting water quality improvements and to find ways to work collaboratively with partners to integrate land use and water planning as the region becomes more developed. In addition to addressing stormwater management as the cities in this area grow, we are implementing a multi-pronged approach to address water quality and habitat restoration subwatershed-wide, starting with a large-scale invasive common carp management effort.
