Lakeville, MN – Middle Creek Restoration

CHALLENGE

The Middle Creek channel and its banks had become unstable, leading to water quality issues and poor habitat in the surrounding riparian area. The rapid development in Lakeville, with over 1,000 new homes in the past 15 years, altered the watershed and increased runoff intensity, causing erosion, bank failure, and stream incision. The City of Lakeville needed to complete stream restoration before residential and school developments limited access to the stream. Additionally, stabilizing the channel and improving water quality were priorities for the City to protect the stream and wetlands within newly acquired City owned land.

SOLUTION

Moore Engineering, Inc. restored and stabilized 2,500 feet of the stream channel, reducing suspended solids and phosphorus inputs. Moore Engineering’s services included surveying, hydrologic modeling, feasibility studies, design, permitting, public bidding, and construction oversight. The project required close coordination with adjacent developments, including new residential areas, roads, and a school, as well as adhering to environmental permitting conditions. Construction was successfully completed between September and October 2023, meeting the City’s timelines and maintaining progress on all surrounding development projects.

OUTCOME

The completed project stabilized the stream channel, reduced erosion, and improved water quality, creating a more aesthetically pleasing and ecologically valuable amenity for the community. The enhanced stream is adjacent to public trails, a school, and private residences, providing long-term benefits by protecting infrastructure and preventing future erosion. The City was highly satisfied with the project’s success, particularly in how it improved the area’s water quality and habitat while coordinating with multiple ongoing developments.
