Lake Michigan Bluff Drainage Evaluation: Fox Point and Oak Creek, Wisconsin

Stability of soil slopes generally depends on gravitational forces of the slope geometry, soil characteristics, and subsurface water. Improving the stability of soil slopes requires reducing the gravitational forces, increasing the strength of the soil, or lowering the water level; individually or in combination. Gravitational forces can be reduced by lowering the slope height and reducing the slope angle. The strength of the soil can be increased by such methods as, among others, densification and modification in-place, internal reinforcement, and replacement. The water internally within a soil slope can be lowered by reducing water infiltration, or drainage, or both. Implementation of any of these improvement methods may be either difficult or not feasible due to space restrictions or regulations. A water drainage method installed internally within the natural soil slopes along the Lake Michigan shoreline in Milwaukee County, Wisconsin is being evaluated in an effort to improve the bluff slope stability with less disruption in comparison to other improvement methods. The drainage method being evaluated used commercially available wicks, installed with directional drilling methods. To date, the study results show lowered water levels and a calculated improvement in the stability of the soil slope stability.
