In 2014, the Mader Family Trust was considering selling their 77-acre parcel for development. They were interested in maximizing their financial return while also preserving the site’s natural heritage, including a large wetland complex, as a family legacy. The Mader family reached out to MCWD early in their planning process to learn more about the district’s permitting rules.

This sparked some creative problem solving and a collaboration between MCWD, the landowner, and the City of Minnetrista. The partners worked together on a plan to restore 42 acres of wetland and upland buffer, which provided significant natural resource benefits including improved wildlife habitat and flood storage. MCWD provided technical assistance to the landowner, which allowed them to pursue the banking opportunity that might have otherwise been a challenge. The restoration plan also provided the opportunity for the Mader family to take advantage of city density increases allowed through conservation development, which allowed four additional lots within the subdivision and increased the value for the landowner, the city, and the developer.
