WHITE BIRCH TRAIL SHORELINE RESTORATION ON ST. LOUIS RIVER
AMI performed a shoreline protection analysis for a residential property that was experiencing erosion to the steep bank due to high water levels and boat wakes along the St. Louis River Harbor. AMI utilized existing topo and bathymetric data provided by the Owner to determine the quantity of stone required along with a feasible layout for the stone. AMI designed a riprap and geotextile bank protection system that the Owner was able to construction himself over the span of 6-12 months. The Owner was able to manually carry the stones in a bucket, dump them down the side of the slope, or transport large loads during the winter along the ice. Geotextile fabric was used behind the riprap to prevent soil loss through potential wave transmission. A coir log was installed along the top of the stone to limit the amount of riprap required and prevent erosion due to wave runup. Native vegetation options were recommended for the shaded areas to promote slope stabilization. AMI prepared two shoreline protection options for the Owner to choose from. Final design drawings for the Owner were provided.
