We retained a contractor to drill borings along the existing wall to evaluate the subsurface conditions for design of the new wall. Based on this subsurface data, we developed design plans for remediating the old wall and constructing a new mechanically stabilized earth wall.
The design was complicated by the fact that the development site overlies a former saw mill. Deep fill deposits including soft organic soils, wood debris and miscellaneous fill existed at the site. The design plans and specifications included removal and disposal of these unsuitable soils to create a suitable foundation for the new wall construction.
