Wetland Shelf, Stone Toe, and Sill: Lake Huron, MI

This project aimed to replace a 1,900-foot failing steel seawall and protect a shoreline walking path along the St. Clair River in Marysville, MI. The nature-based design, used to stabilize the roadway embankment and reduce erosion from wave action, included a large stone toe and an emergent wetland shelf/bench with over 10,000 native plants. Addition features of the design also included embankment revetment with toe protection, and vegetation near the pavement edge. The project enhances connectivity between the upland and waterway, provides wave attenuation, reduces stormwater runoff from the roadway, and offers additional recreational opportunities.
