Six Mile Creek - East Auburn Stormwater Enhacement Project

The project is part of the Six Mile-Halsted Bay Subwatershed Plan, a planning partnership currently underway which aims to protect and improve natural resources within this priority subwatershed by working closely with partnering agencies to integrate capital investments and maximize public return on investment. This project will enhance two existing stormwater ponds to enhance treatment of phosphorus as well as incorporate treatment of the Church Lake outlet, a lake which routinely fails to meet state water quality standards and contributes to the water quality impairment of East Auburn. The retrofits will include the addition of both a filtration bench and an iron enhanced filtration bench. These improvements will not only enhance phosphorus removal, but also will target dissolved phosphorus, which is rarely accounted for in stormwater BMP application and is a significant driver of the impairment in Lake Auburn.
