Remeandering creek rediscovers natural amenity
Winter crews working with the Minnehaha Creek Watershed District and their project partners will carry out HR Green’s restoration concept designs for the Twin City suburban areas of St. Louis Park and Hopkins, MN. The project design includes a new pedestrian bridge as well as over a mile of new trail and boardwalk with associated viewing areas, overlooks and trailheads.
The rechanneled water, or remeandering, will mimic its historic route of lazy curves to slow down the flow and increase the creek’s length by 1,600 feet. HR Green and Inter-fluve plans will reduce erosion and sediment, creating pools and riffles that will benefit fish and other wildlife. The creek’s path is a segment along Reach 20 of Minnehaha Creek between Louisiana Avenue and Meadowbrook Road. With much commercial and industrial construction over the last 70 years, the creek became hidden away or was straightened, changing the creek to a ditch.
In 2011, HR Green and Inter-fluve examined hydrology, hydraulics, geomorphology and existing infrastructure of the reach. They developed concept designs for restoring a sinuous stream channel, improving wetland and floodplain function, improving site recreation, trail connectivity and integrating stormwater management Best Management Practices (BMPS).
