CONSTRUCTING JEFFERSON COUNTY ALA.'S new solid-waste transfer site to fit an existing county lot challenged the project’s contractor and engineers to develop a unique solution for a potentially severe erosion-control problem. The county-owned site offered good access for large vehicles and seclusion from residential areas, which made obtaining the proper zoning and permits less complicated. However, the site was not ideal for the intended construction.
Its topography includes a large, shale 1.5H: 1V slope, which ranges in height from 70 to 200 ft and covers nearly 2500 lineal ft. The site’s buildable area butts directly against the toe of the slope, leaving only a narrow, 250-ft strip on which to construct the necessary buildings.
