Work consisted of the construction of a new dike system and 8 new ponds with leak detection systems. The new dike system was tied into the existing dam and was made of a 70/30 crushed native material/fly ash blend. The blending process required extensive quality control measures that lead to the solid construction of several new dikes averaging 25’ in height. In order to protect slopes, BCI batched soil cement that was installed 12” thick and then subcontracted the installation of HDPE Liners
