Abstract
A majority of Polk County, in central Florida, has been mined for phosphate in the past. Mining companies use the mined areas to deposit mining wastes such as the tailings sands and highly plastic clay materials that are associated with the beneficiation of phosphate ore. The clays are allowed to consolidate, but often, the resulting solids content or shear strength of the materials is very low even after several tens of years. One such area that was impacted by mining and subsequent clay disposal was to become a mobile home park. The developer did not investigate the subsurface conditions prior to purchase or understand the impacts of the clay disposal on the development of this property. Decisions made by the developer and some of the technical difficulties and construction techniques that were used to overcome some of the difficult soil conditions are discussed herein.

Development on Florida's Phosphate Mine Lands
St. Louis, Missouri
A majority of Polk County, in central Florida, has been mined for phosphate in the past. Mining companies use the mined areas to deposit mining wastes such as the tailings sands and highly plastic clay materials that are associated with the beneficiation of phosphate ore. The clays are allowed to consolidate, but often, the resulting solids content or shear strength of the materials is very low even after several tens of years. One such area that was impacted by mining and subsequent clay disposal was to become a mobile home park. The developer did not investigate the subsurface conditions prior to purchase or understand the impacts of the clay disposal on the development of this property. Decisions made by the developer and some of the technical difficulties and construction techniques that were used to overcome some of the difficult soil conditions are discussed herein.
