Case Study

Bluff and Ravine Stabilization Project – Natural Area

Concept Plan through Final Engineering Services included a multi-year stream monitoring effort for field-measured sediment transport and rates of erosion. That was followed by the Completion of a Stream Restoration Concept Plan, prepared in part for community education purposes. Final Engineering Services included Engineering Design Plans, Fluvial Geomorphic Evaluations, Site Survey, Wetland Assessment, Natural Stream Channel Design, Details, Specifications, and Cost Estimates. The Project length was for 6,750 linear feet of stream channel on Dead Dog Creek, in the Lake Michigan Watershed. Services were performed for Lake County Stormwater Management Commission and the Village of Winthrop Harbor.

Special aspects of the project included design engineering services for the envronmentally sound stabilization of several severely eroding bluffs, ravines, and streambank areas. Sensitive wetland communities and ADID wetland habitat were avoided and protected. Stream design engineering techniques included rock riffle grade control structures rock toe, stepped pools, tree rootball revetments, geogrid slope reconstruction, re-graded slopes, coir logs, and replacement of invasive riparian vegetation with native species in the riparian corridor. With the design assistance of LWC, Lake County SMC received over $1.5M in grant funding for two phases of stream restoration construction and implementation.
