KNIFE RIVER RESIDENTIAL SHORELINE RESTORATION oN LAKE SUPERIOR
AMI performed topographic and drone surveys to a residential property that was seeing erosion on one end of their property due to wave induced erosion and inadequate sized stone. Wave and ice forces were calculated using the topographic and local bathymetric data. This data was applied in the design of the armor stone sizing and layout. AMI prepared two slope and shoreline stabilization options and completed all Army Corps of Engineers, DNR, Township, Sanitary District and County permitting upon final selection. All existing armor stone was salvaged and reused where applicable. The Owner requested 8-10-ton dark colored stones be used in the design to replicate the natural bedrock outcroppings seen on the property. Along with this design the Owner requested that the view of Lake Superior not be hindered while sitting on their deck or inside their house. Final stabilization drawings, construction drawings, and construction estimates for the Owner were provided along with special inspections during the construction of the armor stone revetment. The special inspections included photos to document the construction progress and note any errors to be fixed by the contractor. New 12 ft tall trees were planted along the property line for additional privacy. Native vegetation recommendations included tree and shrub species and were provided for additional privacy barriers as well as added erosion protection from wave spray.
