Minnehaha Creek Watershed District

Request for Proposals: Six Mile Marsh Load Management Assessment

Deadline: October 27th at 4pm

The Minnehaha Creek Watershed District (MCWD) is excited to release a request for proposals (RFP) for engineering and conceptual design services to evaluate opportunities to address phosphorus export from the Six Mile Marsh in Minnetrista. 

This effort will build on previous technical work to evaluate whether the off-line treatment approach identified through prior studies remains the most viable strategy for reducing loading to downstream impaired Halsted Bay. It will further examine the overall treatment opportunity within the Six Mile Marsh and whether MCWD’s Farmhill Circle property can feasibly accommodate a facility capable of providing a meaningful portion of that phosphorus reduction. 

The evaluation is intended to remove uncertainty and refine estimates to provide MCWD and its partners with a clearer understanding of water quality benefits, costs, and key considerations with an off-line facility. This information will help define the potential role and impact of such a project within the broader water quality strategy for the Six Mile Creek-Halsted Bay Subwatershed.
