Painter Creek is part of the Minnehaha Creek Watershed District (MCWD), which includes part of the city of Minneapolis, Minnesota and its western and northwestern suburbs. The Painter Creek subwatershed is 8,667 acres (13.5 square miles) located along the northwestern boundary of the MCWD and includes Painter Creek, Katrina Lake, Thies Lake, large areas of undisturbed or low-density development (including Baker Park Reserve) and numerous wetlands. The project area consists of wetlands connected by Painter Creek flowing through South Katrina Marsh and Painters Marsh, then into Jennings Bay on Lake Minnetonka.
The Painter Creek Watershed has been extensively drained and ditched as a result of increasing demand for agriculture. This caused a loss of wetland and riparian habitat and increased sediment and nutrient loads downstream into Jennings Bay on Lake Minnetonka. The benefits to habitat and water quality have decreased due to the presence of the ditch system, which changed the frequency of which the wetlands are inundated from streamflows.
In September 2010 the U.S. Army Corps of Engineers, St. Paul District completed a draft feasibility study on the restoration of vital habitat units lost to intensive farming and ditching of the subwatershed.
The Minnehaha Creek Watershed District was not ready to proceed in 2010. However, MCWD expressed a renewed interest in pursuing the project based on a modification to the land acquisition requirements. In July 2015, the MCWD submitted a Letter of Intent affirming board support and citing the legacy of cooperation between the Corps and the MCWD.
A Feasibility Cost Share Agreement was needed to update the 2010 feasibility study in order to move forward to the design and implementation phase of the project. A Feasibility Cost Share Agreement was signed in April 2017. A completed feasibility report is expected in fiscal year 2020. Following an approved feasibility study the next step is executing a project partnership agreement for design and implementation.
Section 206 of the Water Resources Development Act of 1996, as amended.
Project design and construction costs are to be shared with the non-federal sponsor. The non-federal sponsor is responsible for operation and maintenance costs. The federal cost limit is $10 million. The preconstruction engineering and design/construction cost share is 65 percent federal and 35 percent non-federal. Costs over $100,000 for the initial feasibility study are cost shared 50/50. Estimates are based on 2008 price levels.
Federal preliminary restoration plan $92,000
Federal feasibility cost $332,000
Total federal funding to date $424,000
Estimated federal cost $2,400,000
Estimated non-federal cost $2,800,000
Estimated total project cost $5,200,000
