Seasonal hillside instability has been a recurring problem along Columbia Parkway for decades in the form of abrupt landslides and gradual downslope movement of the colluvial overburden soils. Heavy rains saturate the overburden soils resulting in landslides and mudslides that overtop the existing wall and cascade onto the roadway, blocking lanes and disrupting traffic. The City of Cincinnati in 2019 sought a long-term stabilization plan, and selected the design-build team of Beaver Excavating Co. as the primary contractor and Geotechnology, Inc. as its geotechnical design consultant. This presentation will discuss the complexities of the landslides and the subsurface exploration program, as well as the design and construction of the stabilization measures.
